7．Cooking programs and classes for children seem to positively influence children's food preferences and behaviors，according to a recent review．And，although the review didn't look at long-term effects of such programs，the findings suggest that such programs might help children develop long-lasting healthy habits．
This research comes at a time when childhood obesity（肥胖） rates have been rising rapidly．More than one-third of adolescents in the United States were obese in 2012，according to the U．S．Centers for Disease Control and Prevention （CDC）．This trend has been caused，at least in part，by a significant decrease in the amount of meals that people consume at home since the 1980s，according to background information in the study．
Cooking education programs，such as Food Explorers，teach children about new healthy foods and how to prepare them．They also stress the importance of eating five fruits and vegetables every day．A volunteer parent explains a new food to the group，and the kids make something based on the lesson，such as fruit or vegetable salad．Depending on the program，kids may be sent home with information about healthy foods to bring to their parents，the review explained．
The study team reviewed eight other studies that tested different types of cooking education programs．Children in these classes were between 5and 12years old，according to the review．The goal of the study team was to learn more about developing an efficient program to encourage healthy food choices that last a lifetime．The study found that it is particularly important to expose kids to healthy foods on a number of occasions．This makes them feel comfortable with the new foods，which helps them build healthy habits．
The study stressed the importance of getting parents involved in（参与） their children's eating habits．Parents who are unable to enroll their kids in a cooking class can achieve similar benefits by having their kids help them while they prepare meals at home．Children are more comfortable at home，which makes them more receptive to new foods because they will make the connection to a positive experience．

36．What can we infer from the second paragraph？A
A．Eating out frequently causes obesity．
B．Childhood obesity is totally caused by eating habit．
C．Childhood obesity rates have been rising rapidly since 2012
D．Food consumption has decreased significantly since the 1980s．
37．On cooking education programs，C．
A．children learn how to prepare foods from their parents
B．children will learn how to cook in the company of their parents
C．children may learn information unknown to their parents
D．children focus more on cooking skills than on information about healthy foods
38．Which of the following is true according to the study？B
A．Parents should let their kids cook independently at home．
B．A greater willingness to try new foods helps building healthy habits．
C．Children who participate in cooking programs are less likely to become obese．
D．Children who take cooking courses are more likely to choose fruits and vegetables as adults．
39．Which of the following categories does this passage belong to？D
A．Education Systems
B．Science and Technology
C．Parent-child Relationship
D．Public Health Research
40．The purpose of the passage isA．
A．to inform the reader
B．to entertain the reader

D．to warn the reader．
8．Plastic bags that can help bread and cheese remain fresh for a long time have been developed by scientists．The technology，which uses chemicals that prevent bacteria and fungi （真霉） from growing，allows food to last longer．It could put an end to throwing away supermarket bread after just a couple of days in the bread bin and cheese that goes mouldy after just a few weeks．
The company，Janssen，has spent two years developing the technology with the plastics manufacturer，Symphony Environmental．They are now in discussion with several food factories and supermarkets about using the bags for their products．The technology could also be used to make credit cards and the new plastic bank notes more hygienic （卫生的）．Tests have shown that the plastic can increase the shelf life of bread and cheese without letting the food go bad．Michael Stephen，director of Symphony Environmental，said the plastic also has the potential to do the same for fruit，vegetables and even meat．He said，"we have come up with a way of making the plastic that is antibacterial and that can be used in food wrapping．We have done a lot of tests on food packaging which have shown such plastic can reduce the mould that grows on both bread and cheese．"
In Britain，around 15 million tons of food is thrown away each year，mostly because it has spoiled or gone bad．Bread is the most wasted food，with families throwing away 4.4 million tons a year-about a third of all the bread purchased by UK families．Tesco，Britain's biggest supermarket，revealed last month that almost half of the bread sold in its stores ended up in the bin．
The technology developed by Janssen and Symphony，which they have called D2P，fixes antibacterial and antifungal chemicals to the plastic．They have found it can control bacteria which can cause food poisoning．It can also control the growth of fungi on bread and others．
Mr．Stephen added，"Initially we expect that it is only used in pipes and door handles，for example，to help reduce the spread of bacteria．It can also be put into man-made fibers so we are doing some experiments to put it into clothes to stop the bacteria that can cause them to smell．"
59．What would happen when people use the plastic bags produced by Janssen？C
A．The sales of bread and cheese would increase soon．
B．Bread and cheese could be stored in a fridge for years．
C．Bread and cheese could be kept for a longer time．
D．Supermarket bread and cheese would be on sale earlier．
60．Why does the writer mention the problem in Britain in Paragraph 3？D
A．To criticize the behaviour of the British．
B．To show the popularity of bread．
C．To criticize the increasing waste of bread．
D．To show the short shelf life of bread．
61．It can be concluded from Mr．Stephen's words thatA．
A．more daily uses for this technology are expected
B．this technology is only used used in pipes and door handles
C．man-made fibers should be improved by this technology
D．people's preference for this technology cannot be expected
62．The passage can be classified asB．
A．an annual review                B．a news report
C．an advertisement                D．a travel guide．
5．The faster your heart       ，the more nervous you'll be．（　　）

1．The hit movie Finding Nemo follows a clownfish from the Great Barrier Reef． In real life，clownfish are among the thousands of colorful sea creatures that call the Great Barrier Reef home．Stretching l，250 miles along Australia's northeastern． coast，the Great Barrier Reef is the longest coral reef in the world．
    A coral reef is a living underwater structure． But these days，the Great Barrier Reef has found itself in trouble．Overfishing，pollution，and high temperatures are harming its health． That's why the government in Australia is trying to help rescue the reef．
Underwater Garden
   While coral may look like a plant，it is actually made up of tiny sea animal．Those sea animals are called coral polyps． 
   As polyps die，they leave hard．shells behind． Other polyps grow on top of the shells．Over thousands of years，they form a coral reef in warm water that is not very deep．
   In many ways，the Great Barrier Reef resembles an underwater garden．  Coral can be hard or soft．It forms in different colors and in strange shapes．Some coral looks like hardened brains． Other coral looks like fans and lettuces．
  The reef bursts with schools of tropical fish，dashing among gaps in the coral．The reef supplies food． and． shelter to creatures living in and around the coral．  Turtles，sharks，sea horses，and crabs are among its many inhabitants．
Helping Humans
     While the reef is important to ocean life，it helps humans，too．  People rely on the reef for both food and jobs． It also provides medicine used to treat disease．  Each year，the Great Barrier Reef contributes about  $ 975 million to the economy through tourism and fishing．
Stressed Out   
    Is it surprising，then，that the Great Barrier Reef is under too much stress？Fishing nets and ships break off sections and damage the reef．  Air and water pollution are also doing harm． At the same time，warmer sea temperatures have caused coral bleaching（漂白） on half of the reef． The high temperatures cause the coral to turn white，often killing it．
Reef Rescue
    In an effort to help save the reef，the government has limited fishing to two thirds of it． That plan increases the number of"green zones．"Those are areas that are off-limits to fishermen and boats． However，tourists and researchers can still visit them． Many fishermen are upset about the plan because they rely on the reef for jobs．
     The Australian government says that its plan will help keep the reef safe from some threats．"It is very important that we give   B reef proper protection for the future，"said one government official．  The reef is Australia's greatest natural treasure．

18．Losing weight comes with a lot of health benefits-including making your brain sharper．
Yes，it turns out that overweight may damage cognitive functions such as memory and attention．There have been few studies of overweight and cognitive functioning，possibly because it is generally believed that it is not a primary risk cause for poor cognitive performance．Losing weight，therefore，may help improve these mental functions，according to a new research led by John Gunstad，assistant professor of psychology at Kent State University．
Growing evidence suggests that being fat is linked to cognitive deficits（缺陷）．So Gunstad and his team guessed that losing weight might improve mental function．For their study，they measured memory and attention in a group of l 50overweight participants，some of whom had some kind of operation for weight loss and some did not．All of the volunteers completed mental skills tests to assess their abilities of memory and attention at the beginning of the study，and again 12weeks later．To begin with．about 24%of the patients showed damaged learning and 23%showed signs of poor memory when tested．At the end of the study，those who had lost weight after operation improved their scores into the average or above average range for cognitive functions．Scores for the volunteers who didn't lose weight dropped even further．
The study helped Gunstad to find out whether losing weight had any effect on mental function．Now that he's seen the positive effect that weight loss can have on memory and attention，he says he will next study those who choose to lose weight by the traditional way-eating healthier and getting more active．He expects that losing weight in this way will have a similarly positive effect on the brain．"If we can improve the condition with operations，then we can probably produce the same change with behavioral weight loss as well，''he says．

63．There is less research on overweight and cognitive functions because researchersC
A．believe overweight only affects our body
B．have focused on ways to sharpen people's mind
C．do not consider overweight a main cause for low cognitive ability
D．are clear about the relation between weight and mental functions
64．The result of Gunstad's study shows thatB
A．losing weight has little effect on people's memory
B．losing weight can improve people's mental functions
C．overweight people are likely to have psychology problems
D．overweight people's abilities of concentration differ greatly
65．What is Gunstad planning to prove next in his research？D
A．Slim people are smarter than overweight people．
B．Healthy diet is better than exercise in losing weight．
C．Traditional ways of losing weight are better than operation

1．The survey about childhood in the Third World shows that the struggle for survival is long and hard．But in the rich world，children can suffer from a different kind of poverty-of the spirit．（51）B，one Western country alone now sees 14，000attempted suicides （ 自杀 ） every year by children under 15，and one child  （52）B five needs psychiatric （心理） advice．
There are many good things about （53）A in the Third World．Take the close and constant relation between children and their parents，relatives and neighbours for example．In the West，the very nature of work puts distance between  （54）A and children．But in most Third World villages mother and father do not go miles away each day to work in offices．（55）C，the child sees mother and father，relations and neighbours working （56）D and often shares in that work．
A child （57）A in this way learns his or her role through joining in the community's work：helping to dig or build，look after animals or babies---rather than through playing with water and sand in kindergarten，keeping pets （58）C playing with dolls．
These children may grow up with a less oppressive sense of space and time than the western
children．Their sense of days and time has a lot to do with the change of seasons and positions of
the sun or the moon in the sky．Children in the rich world，（59）C，are provided with a watch as one of the （60）Bsigns of growing up，so that they can（61）A along with their parents about being late for school times，meal times，bed times，the times of TV shows．
