20．Cellphones help us easily find people anywhere at any time．However，using cellphones too often may cause cancer．（61）It's reported that people who used a cellphone for 10 years or more were more likely to get brain cancer．
The suggestions below may help you reduce the risk（风险） of cancer：
◆When using your cellphone，try to keep it away from your body as much as possible．Don't put it under your pillow（枕头） or on a bedside table when you sleep．
◆When you're on the cellphone，use the speaker．In this way，you have just 1/100^th of the contact with radiation you have when you hold （63）it to your ear．An earphone is also a good idea．
◆Try to keep your conversations short．If you need to talk longer，use an ordinary phone instead．
◆Change ears when you're using your cellphone．Before putting it to your ear，wait until the person you are calling picks up the phone．
◆Your phone gives out radiation when you talk or text，but not when you're listening or getting messages．（64）多听和少说能降低癌症风险．
◆Do not use your cellphone when the signal is weak or when moving at a high speed，for example in a car or train．At high speeds your phone is trying to pick up signals，and this increases the radiation it gives out．

19．Once upon a time，a boy was walking through a wood and he thought he could hear a sad cry．Following the sound he came to a big，round，mysterious，grey fountain．The sad sound seemed to be coming from the fountain pool．The boy swept aside the pool's dirty surface water and saw a group of grey fish swimming in a slow circle through the pond．
Amused by this，the boy tried to catch one of these incredible talking fish．But when he stuck his arm into the water it turned grey right up to the elbow．As this happened，a huge sadness entered into him，and he suddenly understood how sad the fish were feeling．

From then on，he set about looking after countryside．He cared for the plants，and he did what he could to keep the water from being polluted．He encouraged others to do the same．He was so successful that his arm started to recover its normal color．When the grey had disappeared completely，he started feeling happy again，and he decided to go and visit the fountain．When he was still some way from the fountain he could hear the fish singing happily．

18．In real life，most people seem confident．But when they can't have things they want，they are upset and lose themselves．Do you want to learn how to be yourself？Here are some suggestions．
Be kind to yourself
Appreciate what you have done．Everyone has different talents which can help to make the world become a better one．Remember you don't need to satisfy everyone．No matter what others think of you，just be yourself．
Make good friends
Always make friends with people who are willing to make you feel better about yourself．Good friends neither talk about how great they are nor praise you a lot．They enjoy being with you，not because you are like them，but because you are yourself
Think about your family．
The values of your family are to give you what really need．Maybe you can't get help when you have small problems．But you can learn how to depend on yourself．When you meet big problems，your family will always be with you．
Hold on to your dream
Holding on to your dream can make you braver and stronger．On the way of achieving your dream，you'll know who you are and what you want．Even though you can't achieve it，you'll find you are better and you can still live a normal life．

A new study finds that plants communicate with one another to warn of danger．
We often consider plants as the furniture of the natural world．They don't move； they don't make sounds，they don't seem to act on anything．But as is often the case，plants talk to each other all the time．And the language is chemical．
Over the years，scientists have reported that different types of plants，from trees to tomatoes，give out chemicals into the air to help neighboring plants．These chemical warnings can spread information about one plant's disease or infestation（虫害），so other plants can protect themselves．But how plants receive and act on many of the information exactly is still mysterious．
In this week's Science Magazine，researchers in Japan offered some explanations．They have found out one chemical message and traced it all the way from beginning to end．
The scientists looked at tomato plants infested by a common pest（害虫）．To start out，they grew plants in two separate plastic spaces connected by a tube（管子）．One plant was infested and placed upwind and the other was uninfested and placed downwind．The downwind plants were later exposed（暴露） to the pest．The results showed that plants near sick neighbors before were able to protect themselves better against the pest．
They found one chemical appeared more often in the exposed plants．The chemical is called HexVic．The scientists discovered where HexVic come from，and put it over healthy plants．Those plants were then able to produce HexVic．Researchers made sure that uninfested plants could fight off bugs and diseases．How do they know when to protect themselves？They are warned first by their friendly plant neighbors．
It is not a simple story，and it may be happening in more plant species than tomatoes．It may also be happening with more chemical signals that are still unknown to us．In a word，we know that plants not only communicate，but also look out for one another．

42．The underlined"traced"in the fourth paragraph probably meansB here．
A．reported B．followed C．doubted D．developed
43．For scientists，which are the right steps to watch tomato plants infested by a pest？C

②Place the uninfested plant downwind．
③Expose the downwind plants to the pest．
④Grow plants in two separate plastic spaces connected by a tube．
A．③①②④B．①④③②C．④①②③D．④②①③
44．You can put the sentence"The researches also studied leaves from exposed plants and unexposed plants．"At the beginning ofD
A．Paragraph 3 B．Paragraph 4 C．Paragraph 5 D．Paragraph 6
45．Which of the following can be the best title of this passage？B
A．Communicating Plants and Terrible Diseases
B．Talking Plants and Friendly Warnings
C．Protecting Plants and Clear Information
D．Growing Plants and Mysterious Chemicals．

Finally，Michael's little sister was born．But she was in a very serious condition．The doctor told the parents there was very little hope．They kept the baby girl in the ICU（重症室）．Karen was so sad．She decided to say goodbye to the baby．Michael，however，kept asking his parents to let him see his sister．"I want to sing to her，"he would say．Finally Karen decided to take Michael to his sister．This might be the last time he saw her alive．
Michael looked at his baby sister．After a moment，he began to sing．In the lovely voice of a 3-year-old，Michael sang："You are my sunshine，my only sunshine．You make me happy when skies are gray．"Suddenly the baby girl seemed to be better．Her heart beat well little by little．
"Keep on singing，Michael，"encouraged Karen with tears in her eyes．"You never know，dear，how much I love you，please don't take my sunshine away．"As Michael sang to his sister，the baby's breath（呼吸） became smooth．
