What time does your school start？Do you wish you could get up later every morning？You are not alone if your answer is "Yes." In the US，many middle school students have the same wish.
In America，many schools start before 7：30 am.But that may change soon.A new law has been passed in California.According to the law，middle schools should not start before 8：00 am.The government hopes school children will have longer time in bed.
Many scientific studies show that teenagers are more active in the afternoon and in the evening.Simply telling them to go to bed earlier doesn't work well.Most of them don't get enough sleep because of bad sleeping habits and early school starting time.They need more sleep in the morning.Scientists suggest middle schools should start at 8：00 am.or later.Students can get well ready to learn and they won't fall asleep in class.______The change can help improve students' grades.
While scientists are happy with the new law，many parents disagree with it.They won't be able to send their children to school before they go to work.They also fear that later school starting time will lead to later ending time.As a result，their children will have less time to take part in after﹣school activities.

Medical researches have shown that Chinese vaccines are suitable for most people.And people aged 18 to 59 would be the first ones to get injection.Our government expects people over 60 who are in good health to get injected as well.You'd better ask doctors for advice at first.
Should we still wear a face mask？
Yes.It takes a few weeks or the body to build the ability to fight the COVID﹣19 after injection.Sometimes the vaccines might not work well in the body.So it's best to keep wearing face masks in public and wash your hands often.

Most viruses can be found and killed by our immune system as soon as they enter our bodies.However，some viruses，for example，the coronavirus，are sneaky.They are difficult to recognize and find.These viruses can cause deadly diseases，like COVID﹣19.Human﹣to﹣human transmission can easily occur，and pandemic will therefore break out.Vaccination is by now a simple，safe and effective way to protect us from the diseases.
▲Vaccines are something that "looks" exactly the same as the viruses，mainly made from the viruses that are weakened or killed.They will not make us really ill.They only stimulate and activate our immune system to work，telling it something harmful is coming in.The immune system will know what the "viruses" look like，and send B cells（lymphocytes）or antibodies to find and kill them.Meanwhile，B cells will remember them for the next kill.A vaccine may also give us passive immunity by providing B cells taken from an animal or a human to play the same role.
Scientists have developed more than 180 vaccines to fight against COVID49.The technical approaches of these vaccines can be a little different，but their aims are the same.
Take the inactivated vaccine as an example.In an inactivated vaccine，the coronaviruses are already killed or made into the ones unable to produce more new viruses.When the immune system "sees" them，it will try to kill them.The question is：without enough these viruses• how can B cells remember them？That's why we need to take the vaccine more than one time.Though this vaccine is safe，it might not be as effective as it is expected to be.
The live﹣attenuated vaccine is different.In this vaccine，the viruses are weakened，but they are alive.They can produce enough new viruses to train the immune system to kill and remember them，so people only need to take the vaccine once.The live﹣attenuated vaccine is considered the most effective，but there is a worry：what might happen once these viruses wake up？
Therefore，although vaccination is by now one of the best ways to protect us from COVID﹣19，it can be better.
（1）The coronavirus can .
| A． |
not be killed |
| B． |
not be found |
| C． |
cause deaths |
| D． |
stop pandemic |
（2）Which of the following can be the best topic sentence of Paragraph 2？

| D． |
Vaccines won't make us ill as the viruses do. |
（3）Compared to the inactivated vaccine，the live﹣attenuated vaccine .
| A． |
needs taking more than once |
| B． |
is equally safe |
| C． |
contains viruses that are killed |
| D． |
is more effective |
（4）What can we learn from the passage？
| A． |
Vaccination is good enough to treat COVID﹣19. |
| B． |
The immune system can be more effective with vaccines. |

It seems that food deliverymen （送货员） are always rushing in haste.We can always see them running every minute，and they seem to have lots of things to do the next minute.They wear blue，red or yellow helmets （头盔） and many of them don't follow traffic rules.They drive on the wrong side of the road and run red lights.They use mobile phones when they are driving.
However，not everything goes well with food deliverymen.In the first half of 2017，food deliverymen had 76 traffic accidents in Shanghai.That means every two and a half days，a food deliveryman will die or get hurt on the road.
What makes deliverymen take such risks？The strict rules of the food delivery companies and the worried customers may be the answer.Many companies will fine （罚款） a deliveryman up to 2，000 yuan if he can't deliver the food on time，reported China Daily.Fines also go to those who get bad reviews from customers.
To solve the problem，food delivery service companies need to do some changes.Some cities are also taking action.Shanghai has asked companies to train their deliverymen on traffic rules and safety.Now in Shenzhen，if a deliveryman breaks traffic rules more than twice，then he can't do the job for a whole year.

Have you ever imagined the life in space？The following will show you the astronauts' daily life.
• Eating in space
If you go camping for more than a week with some friends，you will make sure you have plenty of foods and keep them properly.At the end of your camping trip，you would deal with your rubbish properly before the ride home.
Astronauts almost do the same thing when they go to space.Preparation changes with the food type.Some foods can be eaten in their natural forms，such as chocolate cakes and fruits.Other foods require adding water，such as cheese.Of course，an oven is provided at the space station to heat the food.But there are no fridges，so space food must be kept properly.
• Sleeping in space
After a long day at work，nothing is better than a good night's sleep!Just like on the earth，in space astronauts go to bed at a certain time，then get up and prepare for work again.When going to sleep，they have to attachthemselves，so they don't float （漂浮） around or hit their bodies against something.They usually use sleeping bags located in small crew cabins （乘员舱）.Each crew cabin is just big enough for one person.Generally，astronauts have an eight﹣hour sleep each day when they finish their task.
• Doing sports in space
Exercise is an important part of every astronaut's daily life to prevent muscle loss （肌肉萎缩）.Usually，astronauts exercise two hours every day.Lifting 200 pounds on the earth may be a lot of work.But lifting that same object in space would be much easier.That means the things for exercise need to be specially designed，so astronauts can receive the exercise needed.
Living in space is not just all work and no play.Astronauts have fun，too.They like to look out the window and play with their food.Fun plays an important role in the quality of their life.

"Zhu Rong is regarded as the earliest god of fire in traditional Chinese culture，" a space official said. "The first Mars rover was named Zhu Rong.The name symbolizes（象征）light and hope for space exploration（探索）in our country，and means to guide humans to continue exploration."
After leaving the earth last summer，Zhu Rong circled Mars for several months and landed on it in May.In recent years，our country has sent up the world's first quantum satellite（量子卫星），and Chang'e﹣4 has made a soft landing on the moon.We have made great progress in space technology and will soon start building our own space station.

With her eyes feeling increasingly tired and her vision blurry（视力模糊的），l6﹣year﹣old Tian Ting went to the hospital with her parents in January.She was shocked when she found out that her eyesight dropped from 5.0 to 4.6 in only a term. "A few of my friends have had the same experience lately，" Tian said.
In fact，poor eyesight among Chinese primary and high school students rose from 59.2 percent to 70.6 percent in the first six months of 2020，according to the Ministry of Education.
To protect students' eyesight，the Chinese government has worked out new requirements （要求） for school supplies （供应品） and equipments that will take effect （生效） on March 1，2022.For example，according to the requirements，the size of text in students' textbooks should be no smaller than nine﹣point.Teachers should also try not to use projectors （投影仪） or other multimedia equipments （多媒体设备） that are too bright，Beijing Daily reported.There are also requirements for desks and classroom lights.For example，these lights should give off （散发） as little blue light as possible.
Blue light is bad for our eyes，as it can kill the photoreceptor cells （光感器细胞） we need for vision，according to Harvard Medical School.Many of the electronic devices we use every day，like our phones and computer screens，give off blue light.

CHANGSHA﹣Eight pandas moved to their new home in the ancient town of Fenghuang in Central China's Hunan Province on Friday．
This is the first time the ancient town， also a popular place of interest，has welcomed giant pandas． The animals will make Fenghuang their new home．
With the average temperature ranging from 12.6℃to 16.7℃， Fenghuang County takes pride in its over 3，333 hectares of bamboo forest， providing a good living place for giant pandas．
To provide a good living environment for the new arrivals， Fenghuang has built a panda theme park．
Two of the eight pandas， named Long Sheng and Qing Feng， were born in 2000 and 2007 respectively（分别）． The other six pandas were born in 2017． They were transported from southwest China's Sichuan Province to Fenghuang by special trucks．
Before the transportation， the eight pandas were placed under observation in the giant panda protection center， and they are now in good health．
Teng Qiong， director of Fenghuang County Forestry Bureau， said that the pandas were transported in refrigerator trucks for their safety and comfort． Several trucks were rented（租用），with four trucks carrying two giant pandas each， while one truck carried enough bamboo and bamboo shoots for five days， and another empty truck was kept on standby．
"During the transportation， we rested at the high﹣speed service areas for 30 minutes every three hours． The keepers provided food and water for the pandas and carefully observed their health condition，"Teng said．
Construction of the panda theme park in Fenghuang started at the end of 2018． It includes a panda house， a panda hospital， a feed processing room， a tourist service center， a science museum and other supporting projects． There will be 16 professional keepers to take care of the pandas in the park．

Rice is one of the most commonly eaten basic foods around the world.Buying it and cooking it is a daily matter.Yet for many，its presence has been a matter of life and death.It is a main food because it is easy to grow，besides low cost and convenience.A poor community in the developing world may find it difficult to bring in foreign fruits or raise cattle for meat，but it can almost certainly use the land it has in order to grow plenty of rice.
This was the great achievement of Yuan Longping，who passed away on May 22 this year.A great Chinese scientist，Yuan successfully developed what is known as "hybrid rice" which can produce up a 30% higher output.Yuan Longping was born in the year 1930，a time when China was very different.It was a nation，without modern industry，depending on the rice which they grew.The first few decades （十年） of his life were met with major social events，and a rapidly growing population that made food supply not last all the time.This experience left its mark on Yuan Longping，which made him focus on （关注） farming science and work on his research of hybrid rice.
His achievement would see the rice supply in China increasing from 56.9 million tons in 1950 to 194.7 million tons by 2017.By 1991，20% of the world's rice output came from hybrid rice，even if only being planted in 10% of fields.
Always remember，human development begins first with the most basic and sample things，such as developing rice.We should be thankful for scientific thinkers like Yuan.
（1）Why is rice a main food around the world？
（2）What did Yuan develop successfully？
（3）When was Yuan Longping born？
（4）What made Yuan focus on farming science？
（5）How many tons was the rice supply in China by 2017？
The population of the world continues to increase， but in some areas the population is falling．This is true in Europe and especially in Eastern Europe． In Russia， the population is going down by about 100 people EVERY HOUR! Russia's population could fall by ONE THIRD by the year 2050! And in Poland （波兰）the population is also going down because people are leaving to work in other countries．
One of the main reasons is a change of lifestyle． All over Europe people， especially educated women， have a different attitude （态度）to children than their parents．"I have one child and she is enough for me， "said Galina Tereschkova， a doctor from Moscow． "My husband and I both work full﹣time． We can't imagine having more than one child． "Many women decide to have children later in life or not to have children at all． "I don't want to have any children until I have worked for at least 10 years， "said 19﹣year﹣old student Hana Markova from Prague． Her opinion is typical of 18﹣24 year old women everywhere in Europe．
In Poland， the population is going down for a different reason． A lot of people，usually aged between 20 and 30， are leaving the country to work abroad． Poland joined the European Union in 2005 and since then more than half a million people have moved to Britain， Germany， Spain and Italy． Even so， the population of those four countries and many other countries in West Europe is also going down．
Many governments are now encouraging people to have larger families． In France，women now receive nearly 1，000 a month for a year if they have a third child．Austrian women receive 700 a month for three years when they have their first child．
（1）Where in the world is the population getting smaller？
（2）How many children does Galina Tereschkova want to have？
（3）What does Hana Markova want to do before she has children？
（4）Why is the population in Poland going down？
（5）How does the French government encourage people to have larger families now？
At some point in life，many people develop a mental（精神） problem．While most people get over it，for others it doesn't go away easily．
The WHO says that about 20 percent of teenagers worldwide suffer from mental illness．It's thought that the number of teenagers with mental illness around the world will increase by half by 2020．It will become one of the main causes of illness，and even death．
In China，the picture isn't bright，either．About one tenth of teenagers under the age of 17 have a mental health challenge．
The world is changing fast．Study and relationships have always caused stress，but today the stress is much higher than before，the WHO said．
A research centre in Oxford University says that young people today have big stresses at school．For example，they experience bullying（欺凌）．In a 2017 report，the centre noted that the Internet was a special source（渠道）of stress．Online，young people often see "messages about perfection" and this causes the young "great uncertainty about their futures"，says the centre．
Also，according to China Daily，Chinese people don't ask for help with their mental problems．They fear that others will think less of them if they say that they are in mental trouble．Elaine Peng，a US mental health educator，makes a similar point．And in the UK，over three quarters of young people believe their mental problems have a social stigma．It is reported in 2017 that a quarter of young UK people wouldn't ask for help if they developed a mental problem．
Young people who don't ask for help for their condition may be creating problems for themselves in the future．Elaine Peng warned that，"If we hide our mental health，it may remain a problem forever．"
"My message for young people is，if you feel something is wrong with you﹣ask for help，"he told China Daily．
