Jonny，a 15﹣year﹣old student，is checking his dad's old jacket.He says， "You're 45.Dad，you're never going to wear this again.Can I have it？"
Keith has had a bad day at work，and he is feeling old.And Jonny has hit his pain.Keith raises his voice and says，"What？You mean I'm too old to wear the jacket again？"
Jonny feels like this has come out of nowhere，and now he feels hurt. "But I only asked.Why are you shouting at me？
"But I don't like being treated as though I'm too old. " Both of them feel a bit upset.
Have you ever had a similar argument with the people around you？Here are some tips for you to remember when you' re getting mad.
● Accept your feelings and consider the other person's feelings.That means not always making yourself "right" or "clever" and the other person "wrong" or "stupid".
● Explain yourself and not the other person，so you can speak out your ideas by starting with "I" but not "You. ".
● Don't always have to reflect before reacting（回应）.If you feel angry，I think it's a good idea to stop a moment and understand why.
●Don't decide the purpose of the other person by your guessing.Try to work out what he or she is feeling，and admit（承认）it if you were wrong.
Don't forget that it's never too late to start the ways of communicating.

A mind map is basically a tool that connects information around a central subject.It can help you make a knowledge bank to solve problems.A student recently said， "I thought mind mapping would take a lot of time to do but in fact it saves me time.（1）
How to make a mind map？Now follow these steps for making wonderful mind maps.
（2 ） Why？Because starting in the center lets your brain spread out in all directions and express itself more freely and naturally.
Use a picture for your central idea.Why？Because a picture is worth a thousand words and helps you use your imagination.（3） It helps get your attention and makes you work excitedly!
Connect your main branches （分支） to the central picture and connect your second﹣and﹣third﹣level branches to the first and second levels，etc.Why？Because your brain works by connection（4） If you connect the branches，you will understand and remember a lot more easily.
Use one key word every line.Why？Because every single key word can make you learn more clearly and easily.
（5） Why？Because each picture，just like the central picture，is also worth a thousand words.So，if you have 10 pictures in your mind map，they are already worth 10，000 words of notes.
Try to use more colors.Why？Because colors are as exciting to your brain as pictures.Color adds great energy to your creative thinking，and is fun!

School Gardens Could Help Children Try More Vegetables
It's not always enjoyable for children to eat vegetables.But what if a garden is built in the school？New research suggests that a gardening program in schools can increase children's vegetable intake（摄入量） .
How the Study Was Carried Out
The study was carried out in eight schools，Each school was in the gardening program for one school year.Every child in grades 3﹣5 received a total of eighteen 60﹣minute lessons across the school year.In the program，each school built a garden，where children learned to grow their own fresh produce，like fruit and vegetables.
The Benefits Children Could Get
The study found that vegetable intake if the children who grew their own produce increased greatly across the year.Related studies show that increased vegetable intake can improve health and cut the risk of chronic diseases（慢性疾病）.Not only are there benefits to health，increasing the variety of vegetables children are exposed（接触）to may also make mealtimes much easier." Children who are often exposed to a variety of vegetables are more likely to try new foods，" explains Dr.Kerry Jones.For children，growing their own food is a powerful tool to increase their intake of the food.（2）
Any opportunity to expose children to more vegetables is meaningful. "If children are learning about vegetables at school，it's important to encourage this interest，" says Jones.Parents can listen to their children about what they have learned and read the handouts they bring home from school.Parents and children can also read books together.Younger children can enjoy reading stories about vegetables with parents who offer useful message.Older children may enjoy searching through cookbooks with parents to find new dinner ideas to cook vegetables in a tasty way.Besides，a small planter box in a sunny part at home can encourage children to understand more about where their food comes from.
Teaching children to grow their own produce is a great way to increase their preference for the produce.If children are taught to enjoy vegetables early in life，they will probably continue eating vegetables in the long term.
（1）What did children do in the gardening program？
A.They did research on new plants.
B.They grew fresh produce at school.
C.They took home green vegetables.
D.They built gardens for their classes.
（2）Which of the following would be the best heading for Paragraph 4？
A.Ideas to Encourage Children to Cook at Home.
B.Ways to Expose Children to Vegetables at Home.
C.Reasons Why Parents Should Understand Children.
D.Suggestions Which Children Could Get from Parents.
（3）What can we learn from the program？
A.Parent' support might improve children's reading.
B.School programs could develop students' creativity.
C.Doing studies can prepare students for future learning.
D.Hands﹣on experience may influence children's preference.
Do you ever give up easily in difficult situations？If so，imagine yourself as someone with great abilities，like Batman （蝙蝠侠）.It will help you feel strong.You will not give up easily and will probably do better.This is called the Batman Effect （效应）
In a study，researchers gave three groups six﹣year﹣old children a difficult task to complete on a computer.In Group One，the children were told to repeat asking themselves， "Am I working hard？" In Group Two，the children were told to ask themselves the same question in the third person一as in"Is Sam working hard？" And in Group Three，the children were told to imagine themselves as Batman and ask themselves "Is Batman working hard？" Researchers found that the children in Group Three did the best.
How can you make use of the Batman Effect ？Imagine yourself as someone who is the best for the task you are doing If you're facing a personal difficulty，imagine yourself as a wise family member.If you're running a race at school，imagine yourself as a top runner.In this way，you can become a little more like the person you wish to be.

Mostly， inventions happen because someone works to solve a problem． Kids are natural inventors．They often create amazing thing from simple ideas．Here are a few examples that might make you wonder，"Why didn't think of that？"
Popsicles
Popsicles were invented by 11﹣year ﹣old Frank Epperson in 1905． He forgot a drink of juice and left it with a stir（搅拌） stick in it outside on a cold night． The next day it was ice． Because of this he couldn't drink it any more， but he could eat it． It tasted good! These ice sticks became popular among kids at school in summer because they were delicious and helped them stay cool．
More than a hundred years later， popsicles are sill one of the best summer treats!
Crayon Holdans
When 11﹣ year﹣ old Cssidss Coldstein needed crayons for a school project，she had a hard time because，there were so many small or broken ones．She found some small clear plastic tubes（管子）at home．Although the tiny tube were usually filled with water to keep flowers fresh， she found that they fit tightly （紧紧地） around the crayons． She was now able to hold them easily．This is how she invented Caryon Holders．
Wristies
When snow gets in kids' gloves and their hands get wet， they feel uncomfortable.10﹣year﹣old Kathryn Gregoary decided to do something about it．She created the wristies as she wanted to keep her wrists（手腕）warm and dry． Wristies are long gloves with no fingers and they are worn under your coat． They help you when you work in the cold because your hands stay warm while you use your fingers． With her parents' help， Kathryn also opened a small shop where she sold her wristie． And she still runsit today．

When I was in the middle school， I seldom raised my hands to answer questions in class． And I found lots of my classmates were just like me． When the teacher asked a question， I always lowered my head because I was afraid that the teacher saw me．
One day， in a foreign language class， Mr． Black gave us a lesson． He wanted us to be active in class， so he asked us some questions，but no one answered．"At the beginning of the class， let me tell you a story．" He said．
"When I came to the United States to study， the university often invited famous people to make speeches． Before the beginning of every speech， I found an interesting thing． The students around me always took a cardboard folded （折叠） in half，wrote their names in bold （粗体） with the most eye﹣catching color，and then placed the cardboard on the seat．So when the speaker needed the answers from the students，he could see and call a listener' s name directly．"
"I couldn't understand that． My classmates told me the speakers were all top people who meant chances． When your answer was to their surprise， it meant they might give you more chances．In fact，I really saw a few students got great chances because of that．"

Critical thinking（批判性思维） is trying to improve the way you think． People use critical thinking in every area of life to solve problems and evaluate claims（评估主张）．
Like every other skill， critical thinking takes practice． When a problem comes our way， we need to think critically to decide how to solve it． When we see an advertisement， for example， we should stop and think． Advertisements are made to make people feel certain that they are true， and then people can buy the products． But is what the advertisement says true？ Is it making a claim？ Or does it only interest us？ Critical thinking is important and stops us from making poor choices． In fact， we are using it if we ask questions naturally about what we see．
Practice makes perfect． While you are growing in critical thinking， you'll become a wiser and more thoughtful person． There are many ways of doing practice． Here are a few．
★ Read about a topic people disagree on． Look at articles or books on all sides of the subject． For each side of the subject， think carefully and evaluate it．
★ When you see or hear a claim， ask questions about it． Who is making the claim and why？
★Evaluate your own thinking． Where and why do you think uncritically？ How can you improve？
Critical thinking should be part of everything we do． It may help you to succeed at work or school ．Make yourself into a habit of critical thinking． Change your thoughts and change your world．

Students at a primary school in Fuzhou，Hast China's Fujian Province were required to clean the school toilets to help them develop good habits．But some parents are strongly against the idea．They can't see the advantages of students doing such chores （杂亊）．They think that the school should provide students with a proper education，not the chance to be school cleaners．
In fact，parents，schools and society play an equally （同等地）important role in developing the character of students．It is good for schools to give students such tasks，because few of the students will do them at home．Their parents want them to do homework only．
In recent years，some parents will make mountains out of molehills when students are asked to do some chores in schools．Some complain about the teachers if their kids get hurt in schools； some even challenge the schools'teaching methods and management．As a result，many primary schools，especially those in big cities，do not let students join in outdoor activities during breaks，fearing that they might get hurt．This is bad for the development of students'best qualities．
What the primary school in Fuzhou is doing is worth praising．Doing chores can put a sense of responsibility into students'minds and teach them the spirit of rules as well as teamwork．Also，it can make students'in﹣school experiences more meaningful．
34．A primary school in Fuzhou required the students to ．
A．do homework only
B．finish homework at school
C．clean the playground
D．clean the school toilets
35．Some parents think that the school should provide students with ．
A．a proper education
B．a chance to be cleaners
C．a chance to be teachers
D．more housework
36．The underlined phrase "make mountains out of molehills" means
A．愚公移山
B．山穷水尽
C．小题大做
D．眉飞色舞
37．What is the main idea of the passage？
A．Students shouldn't do any chores in school．
B．Parents require students to do some chores in school．
C．Some parents think doing some chores is harmful to students．
D．Doing some chores can develop students'good qualities．
When it comes to the letter grade on your test or homework， you might notice that there is no letter E． Have you ever thought about why that is so？
In the A， B， C， D and F grading system， the first four letters are typically considered passing grades． An F in this system simply stands for"fail"．The word"fail"happens to start with the letter F， which seems to leave out the letter E． The fact of the matter is that any letter can mean "not﹣passing" or "fail"．Some schools have U grade for"unsatisfactory"，or I grade for "incomplete"．
Even with all this said， we should also point out that E grade actually has been used pretty commonly throughout the history of letter grades in the US．
The first college in the US to use a letter grading system like the ones we use today is Mount Holyoke College． In 1897，they began to use the following grading scale：
A： 95﹣100%（excellent）
B： 85﹣94%（good）
C： 76﹣84%（fair）
D： 75%（barely passed）
E： below 75%（failed）
We can see the inclusion of E instead of F．
Gradually，the letter grading system became more popular throughout the US． However， many schools decided to drop the E grade and go straight to F．There is no evidence（证据） to really support this，but one possible explanation is that teachers were worried that some students and parents might mistake E for "excellent"．
Why do we have letter grades？ Well，part of the reason is that they made grading simpler during a time of great change for schools． As the 20th century began，growing cities and an increase in immigration led to larger school classrooms． Most teachers at that time thought this new letter grading system was an easy，fair and clear way to grade students．
Today，more and more people argue that letter grades don't fully reflect（反映） student learning．However，as teachers try to improve grading methods，many parents continue to favor the letter grades they got as kids．They are familiar（熟悉） and easy for parents to understand． So while they might not be perfect， the letter grades probably aren't going away any time soon．
（1）what does an F stand for in the A、B、C、D and F grading system？
（2）when was the letter grading system first used in the US college？
（3）what is one possible explanation for dropping the E grade？
（4）what did most teachers think of the letter grading system in the 20th century？
（5）why do many parents still prefer the letter grades today？
Say you're sitting around with some friends playing video games and someone mentions a game that happens to be one of your favorites．"Oh，that game's easy．So not worth the time，"one of your friends says．The others agree．Although you enjoy the game quite a lot，not wanting to argue with them，you go along with the crowd．
You have just experienced what is commonly referred to as peer pressure（同伴压力），also called peer
influence．You will adopt a certain type of behavior，dress，or attitude in order to be accepted as part of a group of your"peers"．As a teen，you are likely to have experienced the effect of peer pressure in a number of different areas．
We are all influenced by our peers at any age．For teens，as school and other activities take you away
from home，you may spend more time with your friends than with your family．As you become more
independent，your peers naturally play a greater role in your life．
According to Dr．Casey from Cornell University，teens are very quick and accurate in making decisions
on their own and in situations where they have time to think．However，when they make decisions in the
heat of the momentor in social situations，their decisions are often influenced by factors like peers．In a
recent study，teen volunteers played a video driving game，either alone or with friends watching．The
researchers discovered that the number of risks teens took more than doubled when their friends were
watching，compared with when they played alone．This shows that teens may find it more difficult to control risky behavior when their friends are around，or in situations where they are extremely angry．
Just as people can influence us to make unwise choices，they can also influence us to make good ones．A teen might join in a volunteer project because his or her friends are doing it，or get good grades because his or her friends think getting good grades is important．In fact，friends often encourage each other to study，or try out for sports．
While we are always influenced by those around us，the decision to act or not is up to us．So when it
comes to decision making，the choice is up to you．
52．According to the passage，Dr．Casey probably agrees that teens ．
A．like to play driving games with their friends
B．prefer situations where they have time to think
C．may take more risks when their friends are around
D．are slow in making decisions when they are on their own
53．The words" in the heat of the moment"in Paragraph 4 probably mean" "．
A．when teens avoid possible risks
B．when teens trust their judgment
C．when teens lose control over their anger
D．when teens give consideration to situations
54．What can we learn from the passage？
A．Teens are eager to be different from their peers．
B．Peer pressure has effects on both teens and adults．
C．Peer pressure does more harm than good to teens．
D．Tees think it challenging to get good grades at school．
55．Which of the following would be the best title for the passage？
A．Peer Pressure：Is It Necessary to Deal with It？
B．Peer Pressure：Is It Possible to Get Away from It？
C．Peer Pressure：Its Benefits to Teens and Friend Making
D．Peer Pressure：Its Influence on Teens and Decision Making．
In the past， I thought I was terrible at many things， such as math， French and science． Although I was good at drawing， I wasn't the best in my art class．I wanted to find out who I was，what I liked and how I could do it better．So， that winter，I took a notebook and kept my diary． When I filled that notebook，I started another one， and then another．
Keeping a diary helps a lot． Studies have shown that people who keep a diary sleep and feel better． It helps people remember what once happened such as dreams， friendships and happiness． Writing about bad feelings can also help brains get over themand move on． Personally， I learn better about myself and my relationships with others by keeping a diary．For example，when I am fighting with my dad， I'll try writing from his point and it works! If I want to compare myself with my classmates．I'll write something like，"I might not have clear skin， but I like my eyes．"
Right about now， you might be thinking： it sounds great， but I'm not a good writer； or I'd love to keep a diary， but my handwriting is terrible． Don't worry! Keeping a diary is not like doing your homework ﹣there are no rules， so do whatever feels best．
（1）What was the writer good at in the past？
A． Math．
B． French．
C． Science．
D． Drawing．
（2）What does the underlined word "them" refer to（指的是）？
A． Studies．
B． Bad feelings．
C． Friendships．
D． Brains．
（3）What is the second paragraph（段落） mainly about？

Mr. Guo is a teacher from Xi'an． He asked his students to hand in their homework through a QR code（二维码）．"We spent an hour or two in class learning how to generate（使产生）the codes， and in the end everything gets easier，" said Guo．"When students finish the homework， they keep it on WeChat． Then， each student makes his own QR code and gives it to me． So I can check their homework everywhere using my computer or telephone．"
The QR codes can be sent to Mr. Guo by email， QQ and WeChat． When Guo scans （扫描） his students' QR codes， their homework appears on his phone． He finds that their homework becomes more creative， with many pictures， music and even videos．
Guo's students like the new way and think it is interesting． "We are living in the information age． Many students like to work with computers， which makes learning more fun．" said Tingting， a student of Guo's．
"The paper is not easy to keep， but the code is easy to keep and share．" Guo said，"It is worth trying to use new technology in education． Education itself is a kind of creation． I don't want my students to fall behind the times．"
However， some parents are worried． They are afraid that their children will spend too much time on computers and less time communicating with teachers． But in fact， it's unnecessary． Students still need to look up information in books and write it down when they do their homework． They only use the code when they hand in their homework， which doesn't take them too much time． Also for teachers， it allows them to check the students' homework at any time． And it's also an easy way to share homework with other students．
