Since the gene，calle ( http: / / www.21cnjy.com )d DAF 16 in worms，was found in many animals and in humans，the finding could open up new ways to affect aging，immunity(免疫)and resistance in humans，the scientists said.21教育网
“We wanted to find ( http: / / www.21cnjy.com )out how normal aging is being governed by genes and what effect these genes have on other traits，such as immunity，”said Robin May of the University of Birmingham，who led the study.2·1·c·n·j·y
Populations across th ( http: / / www.21cnjy.com )e world are aging at a surprising pace，bringing potentially big challenges for health and social care systems.A study by Danish scientists last year found that half of babies born in the rich world today will live to celebrate their 100th birthdays.Scientists are eager to find out how people age to try to develop drugs to help them stay healthier as their lives extend.【来源：21·世纪·教育·网】
“What we have f ( http: / / www.21cnjy.com )ound is that things like resistance and aging tend to go hand in hand，”May said in an interview.www-2-1-cnjy-com
May's team compa ( http: / / www.21cnjy.com )red longevity，stress resistance and immunity in four related species of worm.They also looked for differences in the activity of DAF 16 in each of the four species，and found that they were all quite distinct.2-1-c-n-j-y
May said DAF 16 was ac ( http: / / www.21cnjy.com )tive in most cells in the body and was very similar to a group of human genes called FOXO genes，which scientists believe play a role in the aging process.
“The fact that su ( http: / / www.21cnjy.com )btle(微妙的)differences in DAF 16 between species seem to have such an impact on aging and health is very interesting and may explain how differences in lifespan and related traits have arisen during evolution，”May said. 21*cnjy*com
1．In which section may the text appear in a newspaper 【来源：21cnj*y.co*m】
A．Education. B．Science.
C．Entertainment. D．Culture.
2．According to May，________.
A．resistance has a lot to do with aging
B．FOXO genes can be found in worms
C．genes play the same role in different species
D．new drugs will change the genes in older people
3．What can we know from the third paragraph
A．New ways have been found to affect aging.
B．Babies in the rich world will all live longer.
C．Present social care systems are poorly managed.
D．Aging populations are causing more challenges.
4．From the text we know that DAF 16 ________.
A．is a gene that is only found in worms
B．can make people live longer
C．has an effect on aging and immunity
D．has been quite familiar to scientists
5．What can be the BEST title of the passage

Ⅲ.阅读理解
Genetically ( http: / / www.21cnjy.com )modified(GM)(转基因的)crops have made an enormous positive influence on the world. In recent years，GM technology has brought much benefit directly to farms, reducing the use of poisonous chemicals that kill pests of plants，and reducing greenhouse gas emissions(排放)．【版权所有：21教育】
A particular ( http: / / www.21cnjy.com ) concern among farmers in developing countries is the loss of crops to insect pests.One way to fight this problem is to use chemicals，but this behavior will do harm to the health of farmers，the environment，and the people who eat the food.Instead，biotechnology can be used to increase production of pest resistant crops.For example，in Africa，the sweet potato serves as an important crop，but viruses(病毒)can dramatically destroy its output by up to 80%.The Kenya Agricultural Research Institute，however，has developed a genetically modified sweet potato that can increase crop production by 18－25%.What's more，this new kind of potato has genes that resist damage due to bad climate or unexpected natural disasters.
The use of genetically ( http: / / www.21cnjy.com ) modified foods can have a positive effect on the economy，especially in less developed countries.GM crops have already led to economic growth in South Africa，according to some studies.Because GM crops require fewer chemicals，farmers can save money on both the costs of pesticides and labor necessary to manage the treatments.This，combined with higher output，allow the farmer to gain more from the product.21*cnjy*com
With an increasing ( http: / / www.21cnjy.com )adoption of GM crops, the use of pest control chemicals has been greatly reduced.In fact，while not necessarily related to food related biotechnology，some GM plants have been developed to take care of heavy metal pollution in some polluted soil. Finally，biotechnology can allow people to receive vaccines (疫苗)that are difficult to distribute.By putting vaccines into food products，organizations can more easily transport them to people in need.
1．We can learn from the text that ________.
A．GM crops benefit the environment
B．farmers fail to grow a lot of plants
C．insect pests do less harm to the soil
D．more greenhouse gas is sent into the air
2．What can we infer from the example of the sweet potato 21世纪教育网版权所有
A．Kenya will have the most advanced technology in the future.
B．Crops can be modified to grow in worse natural environment.
C．Potatoes grown in wet areas can resist different kinds of insects.
D．The adoption of GM potatoes may do harm to the farmers' health.
3．Which of the following can be concluded from the text
A．New challenges in world farming have been caused.21教育名师原创作品
B．Certain kinds of GM plants can be used as medicine.
C．Biotechnology will be used in more and more fields.
D．It is difficult to transport GM products in some areas.
4．According to the text，GM crops in poor countries ________.
A．need further research on chemical resistance
B．cost more time and money on farm management
C．suffer fewer natural disasters during the growth
D．offer good economic benefits to farmers
5．The text mainly talks about ________.
A．benefits of genetically modified food crops
B．distribution of some GM crops in the world
C．progress made in potato growth in Africa
D．the use of biotechnology in medical science

认真阅读下面短文，并根据所读内容在文章后表格中的空格里填入一个最恰当的单词。注意：每个空格只填一个单词。请将答案写在答卷纸上的相应位置。
When you are in a plac ( http: / / www.21cnjy.com )e where you are hunting for a new job or career，you will find that there are several things that you should pay attention to.Jobs and careers are fewer than you expect，especially when satisfying employment is something you need to seriously think about.How are you going to find the job that you want and what should you avoid on your way？When you want to make use of your job search，take a moment and think about the things that you must avoid at all costs.
One of the mo ( http: / / www.21cnjy.com )st important rules is never to compromise on the things you ask for or desire or it will badly affect your life and peace of mind.Keep in mind your basic expectations of a dream job.They might be something about money or you might find they have something to do with time off.Whatever they are，make sure that you do not accept a job without them.Your requirements might not be easy to meet，but you have the right to try and achieve them.
What's more，d ( http: / / www.21cnjy.com )on't shy away from odd(临时的)jobs that might actually take you to the place that you want to be in.Sometimes，finding the right job is a matter of luck and chance after you have been searching and putting in a lot of effort.And if something unexpected happens，remember that taking the chance is of great importance and is something you might want to seriously consider.As long as you keep your goals in mind，you are going to be doing much better than other people during the job search.
If you are looking for ( http: / / www.21cnjy.com ) the right job，another thing that you can do to make sure that you get the right kind of employment is to market yourself.When you do nothing to push yourself forward，you will be the one suffering for it.If required，give enough encouragement to yourself and try to confidently look at all that you have.Make sure that you can show your skills and abilities.If the jobs that you have set your sights on are challenging，set goals for yourself and work hard at them.The more efforts you put in marketing yourself，the more your chances of obtaining the job you like will be.
Remember that when yo ( http: / / www.21cnjy.com )u are working on a job search，you should not short change yourself.This is because you will only harm yourself by setting low goals.

Cloning is the pr ( http: / / www.21cnjy.com )oduction of one or more individual plants or animals that are genetically similar to another plant or animal.2·1·c·n·j·y
Cloning creates sev ( http: / / www.21cnjy.com )eral controversial (有争议的) issues in society.A major issue connected with cloning is the increase in population each year.By 2024，the population will reach eleven billion.Scientists already estimate that in 2024 production output by humans must be three times in order to provide for eleven billion people and this figure does not include the faction of cloned individuals.21教育名师原创作品
The general publ ( http: / / www.21cnjy.com )ic's opinion on cloning began to split when Kyeonghee University in Korea successfully cloned a human.Many people believe that the benefits of cloning outweigh the negatives.These benefits come in the form of medical advances like，the use of cloned human embryos in research into genetics and genetically related diseases，and their treatments or preventions.However，continuing research into cloning will only divide society and begin an argument involving ethics (道德规范)．The citizens of the world may eventually end up resembling each other.Cloning also affects emotional relationships greatly.
Cloning may ( http: / / www.21cnjy.com )be a major technological advance，but it has potential to slow the growth of mankind.Too many ethical issues arise due to this technology such as individuality and diversity.The population growth rising at an uncontrollable rate and a split nation represent the other half.All of these issues support the fact that cloning will only stand in the way of a world that keeps improving.【来源：21·世纪·教育·网】

When I was a chil ( http: / / www.21cnjy.com )d，I stayed with my grandmother a lot of the time while my mother was at work.One day some money problems started to arise for my grandmother and the family.They needed a little more income so she decided to sing at the nearby retirement home(养老院)．
So I had to go with ( http: / / www.21cnjy.com )her.I wasn't sure about it at first，but as soon as my grandmother actually convinced(说服)me to get on stage and start singing，I loved it.I just loved seeing that sparkle(光亮)in those people's eyes.They would stand up and dance and clap to the beat of the music.Eventually，we were singing at many of the homes in the surrounding area 5 out of 7 days a week.【版权所有：21教育】

Ⅲ.阅读理解(共15小题；每小题2分，满分30分)
A
Be careful what you s ( http: / / www.21cnjy.com )ay around your dog.It might understand more than you think.A border collie (边境牧羊犬) named Rico recognizes the names of about 200 objects，say researchers in Germany.The dog also appears to learn words for new objects as easily as a 3 year old child would.His word learning skill is as good as that of a parrot or chimpanzee (黑猩猩)．
In one experim ( http: / / www.21cnjy.com )ent，the researchers took all 200 items that Rico was supposed to know and divided them randomly (随意地) into 20 sets of 10 objects each.The dog waited with one of his owners in one room，while an experimenter put a set of 10 objects into another room.Then，the owner told the dog to fetch one of the items.The dog had to go to the other room and bring the object back.In four trials，Rico got 37 out of 40 commands right.Because the dog couldn't see anyone to get visual clues about what to bring back，the scientists concluded that he must understand the meanings of certain words.2-1-c-n-j-y
In another experime ( http: / / www.21cnjy.com )nt，the scientists took one toy that Rico had never seen before and put it in a room with seven toys whose names he already knew.The dog's owner then told him to fetch the object，using a word Rico had never heard.In 7 out of 10 trials，Rico picked the right object，suggesting that he figured out the answer by process of elimination.A month later，he remembered half of the new names，which further impressed the researchers.21教育名师原创作品
Rico is probably sm ( http: / / www.21cnjy.com )arter than the average dog，the scientists say.For one thing，he's a border collie，a breed known for its mental abilities.In addition，the 9 year old dog has been trained to bring toys back by their names since he was 9 months old.21*cnjy*com
It's hard to know if ( http: / / www.21cnjy.com ) all dogs understand at least some of the words we say.Even if they do，they can't talk back.Still，it wouldn't hurt to sweet talk your pup every now and then.You might just get a big，wet kiss in return!
36．What does this passage mainly talk about
A．A dog's amazing memory.
B．A dog's absolute faith to his owner.
C．A dog's nature of understanding man's order.
D．A dog's word understanding and learning ability.21世纪教育网版权所有
37．The purpose of the ( http: / / www.21cnjy.com )experiment mentioned in the second paragraph is to ________.
A．test a dog's ability of recognizing objects
B．make sure a dog can understand certain words
C．test whether a dog has a good memory
D．make sure a dog is as clever as a chimpanzee
38．The underlined ( http: / / www.21cnjy.com )word in the third paragraph can be replaced by ________.
A．exclusion B．similarity
C．deduction D．comparison
39．From the last paragraph，we can infer that ________.
A．dogs can't understand all the words we say
B．dogs can't talk back to their owners
C．be careful about your words to your dog，or you'll be bitten by it
D．be kind to your dog，and you'll get a kind return
B
With only about 1,0 ( http: / / www.21cnjy.com )00 pandas left in the world，China is trying to clone (克隆) the animal and save the endangered species.That's more similar to what a Texas A & M University researchers have been undertaking for the past five years in a project called “Noah's Ark”．
Noah's Ark is aimed ( http: / / www.21cnjy.com )at collecting eggs，embryos (胚胎)，semen and DNA of endangered animals and storing them in liquid nitrogen.If certain species should become extinct，Dr Duane Kraemer，a professor in Texas A & M'S College of Veterinary Medicine，says there would be enough of the basic building blocks to reintroduce the species in the future.
It is estimated t ( http: / / www.21cnjy.com )hat as many as 2,000 species of mammals，birds and reptiles will become extinct in over 100 years.The panda，native only to China，is in danger of becoming extinct in the next 25 years.
This week，Chinese ( http: / / www.21cnjy.com )scientists said they grew an embryo by introducing cells from a dead female panda into the egg cells of a Japanese white rabbit.They are now trying to implant(植入) the embryo into a host animal.
The entire procedure could take from three to five years to complete.
“The nuclear transf ( http: / / www.21cnjy.com )er (核子移植) of one species to another is not easy，and the lack of available (capable of being used) panda eggs could be a major problem，” Kraemer believes.“They will probably have to do several hundred transfers to result in one pregnancy (having a baby)．It takes a long time and it's difficult，but this could be groundbreaking science if it works.They are certainly not putting any live pandas at risk，so it is worth the effort.” adds Kraemer，who is one of the leaders of the Project at Texas A & M，the first ever attempt at cloning a dog.21cnjy.com
“They are tryi ( http: / / www.21cnjy.com )ng to do something that's never been done，and this is very similar to our work in Noah's Ark.We're both trying to save animals that face extinction.I certainly appreciate their effort and there's a lot we can learn from what they are attempting to do.It's a research that is very much needed.”
40．According ( http: / / www.21cnjy.com )to Professor Kraemer，the major problem in cloning pandas would be the lack of ________.
A．available panda eggs
B．host animals
C．qualified researchers
D．enough money
41．The BEST title for the passage may be ________.
A．China's Success in Pandas Cloning
B．The First Cloned Panda in the World
C．Exploring the Possibility to Clone Pandas
D．China—the Native Place of Pandas Forever
42．From the passage we know that ________.
A．Kraemer and his team have succeeded in cloning a dog
B．scientists try to implant a panda's egg into a rabbit
C．Kraemer will work with Chinese scientists in clone researches
D．about two thousand of species will probably die out in a century

You've heard of fast food, but what about slow food
Slow food is an inter ( http: / / www.21cnjy.com )national movement.It promotes home cooking，and the use of fresh, unprocessed produce. It was founded as reaction to the popularity of unhealthy fast food.It also encourages people to buy food from local businesses, rather than large supermarkets.
The movement began in ( http: / / www.21cnjy.com )1986. At that time, McDonald's wanted to open a restaurant in the centre of Rome (Italy). Food writer Carlo Perini，along with others, was against this. So, the Slow Food Organization was born. Today, it has over 100,000 members in 132 countries. And its symbol is one of the world's slowest moving creatures, the snail. The organization's website explains，“The snail was chosen because it moves slowly, and calmly eats its way through life.”
But Slow Food isn't ju ( http: / / www.21cnjy.com )st about the food we eat. It's also about how we eat it. Slow foodies say that in our fast food world with very little time, we've forgotten that eating should be a social activity. They believe families should eat together and talk, rather than watch TV with their dinner while sitting in front of it. In fact, research has shown that if children grow up in a family that eats together at the table, they are more likely to do well in school, and less likely to have behavioral problems or develop eating disorders.
And there's mo ( http: / / www.21cnjy.com )re! Slow Food has sparked an entire Slow Food Movement. This encourages people to slow down the pace of their busy lives. And now, within the movement, there's Slow Money, Slow Travel, Slow Parenting, Slow Art and Slow Media, among many others. In 1999 the World Institute of Slowness was formed.One of the Institute's slogans is a quotation by the famous American actress Mae West. She said，“Everything worth doing in life is worth doing slowly.”Do you agree No need to answer straight away. Have a long hard thought about it. Take your time. And get back to us when you can. 21*cnjy*com
43．If you are a ( http: / / www.21cnjy.com )member of the Slow Food Organization, you may ________.
A．react to fast food slowly
B．buy food from large supermarkets
C．like the animal of snails
D．like to cook at home
44．Why did people start the Slow Food Movement
A．Because food writers are against fast food restaurant everywhere.
B．Because they have plenty of time to enjoy their dinner.
C．Because they think eating should be an enjoyable family occasion.
D．Because they want to slow down the development of society.
45．What can we infer from the text
A．Slow Food Movement has little effect on the whole society.
B．Children growing in slow food families usually behave well.
C．Mae West thought that everything should be done slowly.
D．Slow foodies don't like to watch TV and other entertainment.
46．What is the author's purpose in writing this article
A．To call on people to join Slow Food Movement.
B．To tell people what Slow Food Movement is about.
C．To tell people to think about their life and their food.
D．To call on people to object to fast food.

It was a village in I ( http: / / www.21cnjy.com )ndia.The people were poor. However，they were not unhappy. After all, their forefathers had lived in the same way for centuries.
Then one day, some ( http: / / www.21cnjy.com )visitors from the city arrived.They told the villagers there were some people elsewhere who liked to eat frog's legs. However, they did not have enough frogs of their own，and so they wanted to buy frogs from other places.
This seemed like ( http: / / www.21cnjy.com )money for nothing. There were millions of frogs in the fields around, and they were no use to the villagers. All they had to do was catch them. Agreement was reached，and the children were sent into the fields to catch frogs.Every week a truck arrived to collect the catch and hand over the money. For the first time, the people were able to dream of a better future. But the dream didn't last long.
The change was h ( http: / / www.21cnjy.com )ardly noticed at first，but it seemed as if the crops were not doing so well. More worrying was that the children fell ill more often，and，there seemed to be more insects around lately.www-2-1-cnjy-com
The villagers decid ( http: / / www.21cnjy.com )ed that they couldn't just wait to see the crops failing and the children getting weak. They would have to use the money earned to buy pesticides (杀虫剂) and medicines. Soon there was no money left.
Then the people r ( http: / / www.21cnjy.com )ealized what was happening. It was the frog.They hadn't been useless. They had been doing an important job—eating insects. Now with so many frogs killed, the insects were increasing more rapidly. They were damaging the crops and spreading diseases.
Now，the people are ( http: / / www.21cnjy.com ) still poor. But in the evenings they sit in the village square and listen to sounds of insects and frogs.These sounds of the night now have a much deeper meaning.
47．From Paragraph 1 we learn that the villagers ________.2·1·c·n·j·y
A．worked very hard for centuries
B．dreamed of having a better life
C．were poor but somewhat content
D．lived a different life from their forefathers
48．Why did the villagers agree to sell frogs
A．The frogs were easy money.
B．They needed money to buy medicine.
C．They wanted to please the visitors.
D．The frogs made too much noise.
49．What might be the cause of the children's sickness 21·世纪*教育网
A．The crops didn't do well.
B．There were too many insects.
C．The visitors brought in diseases.
D．The pesticides were overused.
50．What can we infer from the last sentence of the text
A．Happiness comes from peaceful life in the country.
B．Health is more important than money.
C．The harmony between man and nature is important.
D．Good old days will never be forgotten.
Ⅳ.任务型阅读(共10小题；每小题1分，满分10分)

注意：每空格只能填1个单词。
When it comes to st ( http: / / www.21cnjy.com )udying, some students may have different study habits，and some ways of studying may work for one and may not for another student. However, there are certain basic rules that can prove to be effective in studying for an exam.Make a plan for how to develop good study habits that last long. A plan should include a schedule on when to study. It doesn't have to be fixed and can be changed in case something more important and unexpected comes up. Start with a weekly schedule and determine which period of the day is filled with classes. Use some of the remaining time to study. When creating the schedule, one should include laboratory activities and extracurricular (课外的)work and take care of personal things and the job if there is one.
Study when o ( http: / / www.21cnjy.com )ne is fully awake and energetic；it is recommended.Study for no less than 30 to 90 minutes after a meal or two hours every day. If one is tired from work and decides to study，it may not be effective，especially if one find the subject too difficult.It will only give stress and what he learned that night might only be forgotten in the next morning when he wakes up. For some students，they can study anywhere if they want，it could be in the library, study rooms or private rooms. A place where one can pay attention to one's study is recommended.
Make friends with ( http: / / www.21cnjy.com ) those that are also eager to learn and pass the exam or achieve good grades. However, one has to balance the time to spend with friends. Have and keep a healthy relationship with them.
Take down no ( http: / / www.21cnjy.com )tes during the class.The hint (暗示) of some questions teachers give will come out in the exam. Sometimes they repeat the topic more than twice，so pay more attention in class. If one does not understand the topic, don't hesitate(犹豫)to ask questions.A failure in communicating is one of the most common mistakes among students.
Take a five minut ( http: / / www.21cnjy.com )e break or go out and get some fresh air once in a while when studying. It will relax the mind and help one think better. Do come back to study after taking a short break.
