1．Spending two or three hours playing outdoors each day can reduce the chance of becoming short-sighted（近视的），a research shows．It challenges the belief（信念） that short-sightedness is caused by computer use，watching TV or reading in weak light．
The Australian government researchers believe that the sunlight is good for people's eyes．They compared the vision（视力） and habits of 100 seven-year-old children in Singapore and Australia．In all，30% of the Singaporean children were short-sighted-this rate（比率） was ten times higher than Australian children．
Both groups spend a similar amount（数量） of time reading，watching television and playing computer games．However the Singaporean children spent an average （平均） of only half an hour a day outdoors-90 minutes less than the Australian children．
Professor Ian Morgan，from the Australian Research Council's vision Centre，said，"Humans are naturally long-sighted，but when people begin to go to school and spend little or no time outdoors，the number of short-sighted people gets larger．We're also seeing more and more short-sighted children in cities all around the world and the main reason may be that city children spend less time outdoors
Daylight can be hundreds of times brighter than indoor light．But why does playing outside prevent us from becoming short-sighted？Scientists believe that natural light has a special chemical（化学物质） which stops the eyeball from growing out of shape and prevents people from becoming short-sighted．So be outdoors．It doesn't matter if that time is spent having a picnic or having sports．

16．People usually check whether their keys，wallets and phones are with them before going out．But many people in China now have one more important  thing to take，a face mask（口罩）．They hope that it can protect them from the polluted air．
2Since January，many cities in China have seen a lot of foggy days．During these days，people can only see things that are very near them．In Beijing，only five days in January were free of smog．what's the difference between fog and smog？
3According to scientist，fog is made up of tiny（微小的）drops of water and also ice particles（颗粒）during very cold conditions．Smog is dirty air that looks like a mixture of smoke and fog，caused mainly by smoke from cars and factories in cities．
4An offical for the minnistry of environmental protection told Beijing News that PM2.5pollution is the main problem with air pollution．Pm2.5refers to pollution with small particles 2.5mircrometers or less in diameter（直径）．
5According to the Chinese Academy of Sciences，motor vehicles and burning coal are two major factors for PM2.5．
6Poor air is bad for people's health，especially for Children's．Hospital shows that from January 5th to January 11th，half of the patients in the internal medicine department（内科门诊） are there for breathing problems．
7the problem and environmental protection have become a care for the whole nation．Li Keqiang made his last Government Work Report on March 6，2014．The report said that the government should work hard to prevent pollution and give people a healthy living environment．
It calls on people to make full use of energy and resources and cut down on energy use．"we should give people hope through our actions'Li said．

4．根据短文内容判断66-70题的正误．正确的用A，错误的用B
Healthy Eating
Healthy eating is important to us．What and how should we eat to be healthy？
First，we must have enough food，never too much or too little．The food must be clean and we should cook it properly．
Second，it's very important for us to keep a balanced diet．Different kinds of foods are necessary，such as rice，bread，meat，fish，eggs，milk and vegetables．Rice and bread give us energy．Meat，fish，eggs and milk help our bones grow．Fruit and vegetables make us healthy．
Third，we should eat regularly．It's said that half of the students don't have a regular breakfast or don't eat anything at all in the morning．It is bad for their health．In fact，a good breakfast keeps us strong．
In short，we should not only eat enough food，healthy food but also eat regularly．

66．We eat food freely．B
67．We should eat different kinds of healthy foods．A
68．Vegetables are the most important food for our health．B
69．The more regularly，the healthier we are．A
70．All the students don't have a regular breakfast．B．
1．When you watch TV programs about wild animals，it is surprising to see how an antelope （羚羊） can run away from a strong lion．In the wilderness，everyone has his own way to protect himself．Even plants have their own ways to fight off enemies．
Over millions of years，plants have developed their own defense system （防卫系统）．Chemicals are fantastically used by plants to survive （幸存）．By making their leaves，flowers，roots and fruits poisonous （有毒的） to enemies，plants can fight back．
One such plant is the Golden Wattle tree．The British scientist David Cameron has found when an animal eats the tree's leaves，the amount （数量） of poison increases in the other leaves．"It's like the injured leaves telephoning the others to fight together against the enemy，"he said．
The tree also sends defense messages to neighboring plants by giving out a special smell．Golden Wattle trees in the nearby 45meters will get the message and produce more poison within 10minutes．Now，if an enemy eats too many of the trees'leaves，he will die．
Every kind of plant or tree is good at producing a special set of chemicals．Herbivores，like rabbits，can safely eat the leaves of one tree，but they may be poisoned by its neighbor．
In this way，plants have not only developed their own defense system，but also shared it with others．This makes it impossible for a single animal to destroy even a small area of forest．

51．From the first 2paragraphs，we can learn thatB．
A．plants can do nothing against their enemies
B．chemicals are quite useful for plants to survive
C．an antelope can always run away from a strong lion
D．leaves，roots，flowers and fruits of plants are poisonous
52．If animals eat one Golden Wattle tree's leaves，the tree canD．
A．kill the animals with a special smell
B．tell other trees to come to protect it
C．warn other trees against the animals on the phone
D．send defense messages to the neighboring plants
53．The underlined word"herbivores"in the 5th paragraph probably means animals whichD．
A．produce poison                                     B．live on small animals
C．like to eat rabbits                                       D．feed on plants or grass
54．The last paragraph of the passage suggests that this kind of defense system isB．
A．bad for animals                                        B．good for forests
C．helpful to some animals                        D．harmful to forests
55．The passage is mainly aboutC．
A．the examples of protecting forests
B．the balance between animals and plants
C．the ways of plants fighting against enemies
D．the relationship between lions and antelopes．
2．At last（最后），we all passed the exam．
