You think it's " cool " to carry your backpacks and head out to school．But if you don' t know exactly how to choose，load，lift and wear them﹣these all﹣important accessories（配件）can be a pain in the back．Not to mention the neck，head and shoulders．
Backpacks can influence your health．Carrying a heavy load improperly can lead to
poor body position；and even hurt the spinal column（脊柱）．This can cause muscle strain，headaches，back，neck and arm pain．
For example，if it is carried on one shoulder，a heavy backpack forces the muscles and spine to balance the unequal weight．This may increase the possible back problems later in life．
More than 50 percent of young people suffer back pain by their teenage years．Research shows that this could be mainly caused by improper use of backpacks．
Here's some advice to help you carry backpacks comfortably and safely．
Choose the right backpack．Forget leather（皮革）! It looks great，but it's far too heavy．Go for canvas（帆布）．Pick a pack that has two wide，adjustable，comfortable shoulder straps（带子），along with a hip or waist strap，and plenty of pockets．Make sure the pack fits properly and its size is suitable for the wearers body．
Packing it properly．Only put in the pack what is needed for that day．It's a good idea to know what each object weighs．The total weight of the filled pack should be no more than 10 to 15 percent of the wearer's own body weight．Pack heaviest objects close to the body，and place little ones outside， away from the back．
Putting the backpack on．Put the pack on a smooth surface，at waist height．Put on the pack，one shoulder at a time，then adjust（调整）the straps to fit comfortably．Remember when lifting a backpack， or anything，to lift using the arms and legs and to bend at the knee．
The right way to wear a backpack，Both shoulder straps should be used，and adjusted so that the pack fits the body，without hanging to one side．Backpacks should never be worn over just one shoulder．You should be able to move your hands between the backpack and your back．The waist strap should also be worn．

Drones（无人机）are like planes， but come in many shapes and sizes． They have no pilots and controlled from outside the drones． During these years， they have been used to attack（进攻）enemies or move goods in dangerous areas．

Have you ever counted the number of digits （数字）in your mobile phone number？ Your number has 11 digits． You may sometimes find it hard to remember your number． That's because China has the longest mobile phone numbers in the world． Why is that？
The 11 digits can be divided into three parts． Each part has a different meaning． The first three numbers tell you which mobile phone service provider（提供者） you are using． For example， 135 is for China Mobile Communications Corporation and 188 is for China Unicom． The fourth to the seventh digits tell you where the number is registered （注册）． And the last four digits are random（随机的）．
The main reason for using 11 digits is that we have the largest population in the world． We once had 10numbers． But as our population grew， there were not enough numbers for us to use． So we began to use 11 digits starting from 1999． Eleven digits can be used to make tens of billions of mobile phone numbers． That's enough for each person to have seven or eight phone numbers to use in China．
And mobile phone numbers can be recycled． Usually， the service provider will reuse a canceled number after three to six months． If you call a number that you haven't contacted （联系）for a long time， you may find that its owner has changed．
Besides China， Britain and Japan also use 11﹣digit mobile phone numbers． But their numbers always start with 0． So they cannot create as many numbers as we can． Countries like the United States， Australia and India use phone numbers with 10digits． Canada's mobile phone numbers are perhaps the shortest in the world： they use seven digits．
（1）Is China the only country that uses 11﹣digit mobile phone numbers in the world？
（2）What can we know from the fourth to the seventh digits of a mobile phone number in China？
（3）Why does China use 1l digits for mobile phone numbers？
（4）When can a mobile phone number be recycled in China？
（5）Which country perhaps has the shortest mobile phone numbers in the world？
Shanghai is one of the first cities in China to see bike sharing fever． Shared bikes can now be found all over the city． （1） On streets， we can often see riders of your age． Some might even be younger than you． Unluckily， there have been some accidents involving （涉及）shared bikes． （2）
One of the most serious accidents took place in March． One Sunday afternoon， a boy was riding an ofo bike（共享单车）． He was hit by a bus and later died． The boy' s parents were not by his side． （3） He was only about 10 years old．
The good news is that Shanghai has been trying to manage bike sharing by making rules． The rules are still being discussed， but some of the rules have been decided on． （4） Users must be between 1.45 and 1.95 meters tall．
However， it could be hard to make these rules work． Ou Jing is ofo's manager in Shanghai． He said the company had banned （禁止）children under 12 from using its service． Yet， young children can still be seen riding ofo bikes． That's because many ofo bikes use manual （手动的）locks． （5） Ofo has developed electronic locks． However， it will take some time for the company to fix the new locks on all of its bikes．
Most of you are old enough to ride a shared bike． Still， please ride slowly for your own safety． When you finish using the bike， don' t forget to park and lock it properly﹣﹣for everybody's safety．
根据短文内容，从方框中选出五个句子填入文中空缺处，使短文内容通顺完整．

Last month some parents visited a pizza restaurant in Florida with their children． On the door， they saw a sign "NO CHLDREN．" "Why can't we bring our children？" "What on earth does the owner want to do？" The parents were surprised and complained angrily．
So why did the restaurant put up the sign on its door？
Troy Taylor， the owner of the pizza restaurant， found that many parents couldn't control their children and many children couldn't have meals quietly， so they disturbed other customers． Some people said that this was unfair． Mr． Taylor explained his decision． He said that the restaurant was near a busy road， so there might be some danger if the parents didn't take good care of their children． So he made up his mind to ban（禁止） children from his restaurant．
Others supported his decision， they said they were bored of noisy children in restaurants and now they could finally have a place for adults only．
（3）In fact，many other restaurants have also met the same problem． Some have done nothing and others have tried to ban children during certain times of the day． There's one restaurant in Italy． It has been creative in dealing with the problem． They rewarded（奖励）well﹣behaved children to encourage parents to control their children．
（4）These methods may be useful for a while，but it is difficult to solve this problem completely．

Most of us have made an exercise plan， but only a few can follow it． WebMD（an American website） has listed the following tips for making exercise a habit in your life．
1． Do activities you enjoy．
Remember， there's no rule that says you have to go to a sports centre or buy equipment like swimming suits． Many types of activities， such as push﹣up（俯卧撑）， can be done whenever it is rainy or snowy．
2． Exercise after work．
Don't go home first． Few people are so motivated（有动力的） that they will go out again and exercise after they go home and change clothes．
3． Exercise even when you are tired．
Tiredness is not an excuse． While exercising， you breathe deeply and your body makes better use of the oxygen exchange． Then， you will feel energetic．
4． Notice that you are better than before．
It's great when your clothes fit better， you can lift heavier things or take exercise longer． There's something good too， like getting a good night's sleep or thinking more clearly．
5． Walk with a pedometer（计步器）
Not everyone can start out with 10，000steps a day． Use a pedometer， and find out your daily steps． And then， try your best to walk 300extra steps each day． Finally， you can reach 10，000steps a day．
阅读以上信息，用恰当的单词完成下面的短文，每空一词．

Beyond its influence on health， not getting enough sleep can lead to car accidents or other mistakes． Here are what sleep researchers have found about how to sleep．
How much sleep do we actually need？
It is known that all of us naturally need no less than eight hours of sleep per night． When we sleep below six hours per 24， we're at an increased risk of health problems． Some of us think we can make up any of those hours lost during the week on the weekends． Sadly，there is no storage system for sleep in the brain．
Can we train ourselves to need less sleep？
As a study in 1964， a 17﹣year﹣old boy named Randy Gardner stayed awake for 264 hours． How many people could do anything close to that without dying？
When you are reading this， you might say you usually get six hours of sleep and feel just fine． Sleep experts often compare people without enough sleep to drunk drivers： They don't get behind the wheel thinking they're probably going to kill someone．
Can we drink coffee instead of sleeping？
Coffee can keep us awake． Remember， too much coffee may throw off our sleep and energy cycles． So limit coffee and avoid caffeine for four to six hours before bedtime．
Does a sense of purpose connect to sleep quality？
A new research suggests a kind of strong connection between purpose in life and sleep． People who have a greater sense of purpose usually have better physical and mental health， which in turn explains their higher﹣quality sleep． Perhaps developing a sense of purpose in life could be as useful at improving sleep as the healthy habits above．

Nature's warnings
When the sky suddenly turns dark and the wind is strong， watch out! A dangerous storm might be coming． Storms are scary． Watch for flashes of lightning． Listen for thunder． If nature sends these warnings， don't wait for rain． Act right away to keep safe．
Safety Steps
At the first flash of lightning， quickly get inside a building or a car． Do not go into a shed （棚）for protection． It is not closed like a building， so it is not safe．
Even after you are indoors， be careful． It is not smart to go near doors and windows．They can blow in or break． A room with no windows is the safest place to be．
Do not wash your hands during a storm． Do not use anything that runs on electricity either． Water and electrical lines are like roads for lightning． Even if you really want to play computer games， don't! It is better to be bored than to risk getting hurt． Try reading a book instead． Reading is more fun than playing computer games．
If you can't get to somewhere safe， stay out in the open．You may feel safe under a tree，but that is not a good place to be． Lightning is pulling toward tall poles and trees． Stay down in an open space and cover your ears to protect them． Loud thunder can damage your hearing．
