1．American children aren't the only couch potatoes．According to a study of over 70，000teens in 34nations，nearly 1/3of children globally spend three hours a day or more watching TV or on computers．From Argentina to Zambia，Regina Guthold of the World Health Organization in Geneva and her colleagues found most children aren't getting enough exercise and it made no difference if they lived in a rich or a poor country．"With regard to physical activity levels，we did not find much of a difference between poor and rich countries，"Guthold said．"Growing up in a poor country does not necessarily mean that kids get more physical activity．"The study，published in The Journal of Pediatrics，looked at 72，845schoolchildren aged 13to 15from North an South America，Asia，Europe，and the Middle East．The children were surveyed between 2003and 2007．
The researchers defined adequate physical activity as at least an hour of exercise outside of gym class at least five days a week．Children who spent three or more hours a day watching TV，playing computer games，or chatting with friends----except from time in school or time spent doing homework---were classified as sedentary （久坐的）．The researchers found only 1/4of the boys and 15% of girls were getting enough exercise by these definitions.1/4of boys and approximately 30% of girls were sedentary and didn't get enough exercise with girls less active than boys in every country except from Zambia．While the study didn't look at the reasons behind the lack of physical activity in various nations，it is believed that urbanization（城市化） could be a factor as well as to cars and TVs．

9．Children pushed in buggies which face away from their parents may suffer longterm emotional（情感的）and language problems，according to a study published on Friday．
The research，believed to be the first of its kind，found that children who were not facing the person pushing them were less likely to talk，laugh and communicate with their parents．
The findings were based on a study of 2，722parents and babies and an experiment where 20babies were wheeled in buggies for a mile，facing their parents for half the journey and facing away for the other half．Parents using facetoface buggies were twice as likely to talk to their children while the babies'heart rates fell and they were twice as likely to fall asleep，showing that they were feeling relaxed and safe．
In addition，only one baby out of the 20studied laughed while sitting in an awayfacing buggy．
"Our data（數(shù)據(jù)） suggests that for many babies today，life in a buggy is emotionally impoverished and possibly stressful．Stressed babies grow into anxious adults，"said Dr Suzanne Zeedyk，Developmental Psychologist at Scotland's Dundee University who carried out the research．
The study，which was published by National Literacy Trust as part of its"Talk To Your Baby"campaign，found that 62percent of all children observed travelled in awayfacing buggies．
Zeedyk said it would have a negative effect on babies'development if they spent a long time in awayfacing buggies，which would be bad to their ability to communicate with their parent at a time when their brain was developing rapidly．
Laura Barbour of the Sutton Trust，a social mobility charity which funded the research，said buggy manufacturers（制造商） should look closely at the findings．

63．Using awayfacing buggies mayB．
A．benefit both the babies and their parents
B．a(chǎn)ffect babies'language ability permanently
C．help babies communicate with their parents
D．have positive effect on babies'development
64．Which of the following is TRUE according to the passage？C
A．Parents may talk twice with the babies in awayfacing buggies．
B．The study suggests children feel relaxed and safe in buggies．
C．The samples （案例）of the study were 20babies wheeled in buggies．
D．One of the 20babies was twice as likely to fall asleep in buggies．
65．Which of the following would be the best title for the text？A
A．Best for Kids to Face Parents in Buggy
B．Best for Kids to Communicate with Parents
C．Stressed Babies Grow into Anxious Adults
D．Buggy Manufacturers Care about the Finding．

16．In the United States，30percent of the grown-up population has a"weight"problem．To many people，the cause is clear：they eat too much．But scientific experiments do little to support this idea．Going back to the American of 1910，we find that people were thinner than today，yet they are more food．In those days people worked harder physically，walked more，used machines much less，and didn't watch television．
Several modern studies，besides，have shown that fatter people do not eat more on average than thinner people．In fact，some research work，such as 1970study of 3，545London office workers，reports that fat people eat less than thinner people on the average．
Studies show that thin people are more active than fat people．A study by the research group of School of Medicine at Stanford University found the following interesting facts．The more a man ran，the greater body fat he lost．The more he ran，the greater he needed for food．Thus，those who ran the most ate the most，yet lost the greater amount of body fat．

61．What kind of physical problem do many grown-up American have？C
A．They are too thin．                B．They work too hard．
C．They are too fat                   D．They lose too much body fat．

C．Fat people eat more food but lose greater amount of body fat．
D．Thin people run less，but eat more food．

6．Plastic bags are everywhere!Every day，we are handed countless plastic bags：when we go to grocery stores，clothing stores，book stores and restaurants．Yes，sometimes，they are  convenient，but most of the time，they are avoidable．A plastic bag is just not necessary for that apple you are about to eat or that soda you are going to drink right away．Consider these questions：
    Do I need to take as many plastic bags in supermarkets？
    Do I need a plastic bag for an item purchased that is already well packaged？
    Could I bring my own shopping bag when making purchases？
    Plastic bags are the cause of major environmental concerns．It is thought that an average person uses around 130 plastic bags per year．Using fewer plastic bags is a must in solving environmental problems．
Reasons why you should limit your use of plastic bags：
  1．Plastic bags account for a major part of our waste in landfills（垃圾填埋場(chǎng)）．Plastic
    bags are light and hard to contain．Because of this，plastic bags fly easily in wind，float along in the currents of rivers and oceans，and get caught in trees and fences．
  2．Plastic bags are made from a non-renewable natural resource（資源）：oil．Therefore，this contributes to the disappearance of our natural resources．
  3．Countless plastic bags end up in our oceans and cause harm to our sea life．Many sea animals and birds mistakenly eat and choke on plastic or become tied up in plastic bags that are floating around．
  4．There are many better alternatives to plastic bags．Paper bags hold more than plastic bags．But the best alternative to using plastic bags is using cloth bags．

46．What's the main idea of the first paragraph？A
A．Plastic bags are uncontrollable
B．Plastic bags are unnecessary．
C．Plastic bags are inconvenient
D．Plastic bags are dangerous．
47．Which of the following is NOT the reason for limiting the use of plastic bags？D
A．They speed up the disappearance of oil
B．They threaten the lives of sea animals．
C．They do harm to trees and fences
D．They pollute the environment．
48．The best thing people can do to help solve the plastic bag problem is toC
A．stop making plastic bags from oil
B．use paper bags instead of plastic bags
C．bring their own cloth bags when shopping
D．pick up plastic bags found in rivers and oceans．

10．What problems do you have in you study？Do you want to improve the way your study？Do you feel nervous before a test？Many students say that a lack of concentration is their biggest problem．It seriously affects their ability to study，so do their test results．
    If so，use these tips to help you．
    Study Techniques
    You should always study in the same place．You shouldn't sit in a position that you use for another purpose．For example，when you sit on a sofa to study，your brain will think it is time to relax．Do not watch TV while you are studying．Experts warn that your concentration may be reduced by 50 percent if you attempt to study in this way．Always try to have a white wall in front of you，so there is nothing to distract you．Before sitting down to study，gather together all the equipment you need．Apart from your textbooks，pens，pencils and knives，make sure you have a dictionary．If your study desk or table is needed when you are not studying，store all your equipment in a box beside it．
Your eyes will become tired if you try to read a text which is on a flat surface．Position your book at an angle of 30 degrees．
Be realistic and don't try to complete too much in one study period．Finish one thing before beginning another．If you need a break，get up and walk around for a few minutes，but try not to telephone a friend or have something to eat．
Test-taking Skills
    All your hard work will be for nothing if you are too nervous to take your test．Getting plenty of rest is very important．This means：do not study all night before your test!It is a better idea to have a long-term study plan．Try to make a timetable for your study which lasts for a few months．
    Exercise is a great way to reduce pressure．Doing some form of exercise every day will also improve your concentration．Eat healthy food too．
    When you arrive in the examination room，find your seat and sit down．Breathe slowly and deeply．Check the time on the clock during the test，but not too often．Above all，take no notice of everyone else and give the test papers your undivided attention．
64．Which of the following statements is true according to the passage？A
A．Check the time during the exam at a certain time．
B．Your concentration will improve if you study and watch TV at the same time．
C．You should study in a different place every day，so you don't get bored．
D．Staying up all night and studying is tiring，but you will learn a lot using this method．
65．What does the underlined word"it"refer to？C
A．Your dictionary．
B．Your textbook．
C．Your study desk or table             
D．The equipment you need．
66．What can be inferred from the passage？B

11．Can people change their skin colour without suffering like pop king Michael Jackson？Perhaps yes．Scientists have found the gene that determines skin colour．
The gene comes in two versions，one of which is found in 99per cent of Europeans．The other is found in 93to 100per cent of Africans，researchers at Pennsylvania State University report in the latest issue of Science．
Scientists have changed the colour of a dark-striped zebrafish to uniform gold by inserting a version of the pigment （色素） gene into a young fish．As with humans，zebrafish skin colour is determined by pigment cells，which contain melanosomes （黑色素）．The number，size and darkness of melanosomes per pigment cell determines skin colour．
It appears that，like the golden zebrafish，light-skinned Europeans also have a mutation（變異） in the gene for melanosome production．This results in less pigmented skin．
However，Keith Cheng，leader of the research team，points out that the mutation is different in human and zebrafish genes．
Humans acquired dark skin in Africa about 1.5million years ago to protect bodies from ultra-violet rays of the sun （太陽光紫外線），which can cause skin cancer．
But when modern humans leave Africa to live in northern latitudes，they need more sunlight on their skin to produce vitamin D．So the related gene changes，according to Cheng．
Asians have the same version of the gene as Africans，so they probably acquired their light skin through the action of some other gene that affects skin colour，said Cheng．
The new discovery could lead to medical treatments for skin cancer．It also could lead to research into ways to change skin colour without damaging it like chemical treatment did on Michael Jackson．

71．The passage mainly tells us thatD．
A．people can not change their skin colour without any pain
B．the new discovery could lead to search into ways to change skin colour safely
C．pop king Michael Jackson often changed his skin colour as he liked
D．scientists have found out that people's skin colour is determined by the gene
72．It can be inferred from the passage thatA．
A．nowadays people who want to change their skin colour have to suffer a lot from the damage caused by the chemical treatment
B．Europeans and Africans have the same gene
C．the new discovery could help to find medical treatments for skin cancer
D．there are two kinds of genes
73．Scientists have done an experiment on a dark-striped zebrafish in order toB．
A．find the different genes of humans'
B．prove the humans'skin colour is determined by the pigment gene
C．find out the reason why the Africans'skin colour is dark
D．find out the ways of changing people's skin colour
74．The reason why Europeans are light-skinned is probably thatB．
A．they are born light-skinned people
B．light-skinned Europeans have mutation in the gene for melanosome production
C．they have fewer activities outside
D．they pay much attention to protecting their skin
75．The writer's attitude towards the discovery isC．
A．neutral          B．negative
C．positive         D．indifferent．
