Part Ⅱ Reading Comprehension(30 marks)
A
American job seekers ( http: / / www.21cnjy.com ) who use the Internet are more likely to continue active job searches and less likely to drop out of the labor pool when compared to those who do not have access to the Internet, said the Phoenix Center.【来源：21cnj*y.co*m】
Using census (人口普查)dat ( http: / / www.21cnjy.com )a from 2007, the study found that unemployed workers who use broadband, whether at home or a public facility, are at least 50 percent less likely to give up on their job than those who lack such access.Discouragement was cited by the Bureau of Labor Statistics as a major reason for an increase in the rate of unemployment in 2010.As of December 2009, a large number of American workers have given up looking for a job because of the thought that no jobs are available.
According to the P ( http: / / www.21cnjy.com )hoenix Center, the new study provides important insights for policymakers at a time of economic crisis, when unemployment rates are extremely high, which now is more than 17 percent.The US Labor Department's Bureau of Labor Statistics, which carries the responsibility for the government's monthly data on employed and unemployed individuals, estimates that adding “discouraged workers”， who had given up looking for work, would increase the current US unemployment rate above the frequently reported 10 percent level.
By connecting Ameri ( http: / / www.21cnjy.com )can people to jobs and information about how to better find work, use of the Internet gives them hope and encourages the frustrated unemployed to keep on looking even when job prospects are dim, said Lawrence J．Spiwak, president of the Phoenix Center.
“These new findings ( http: / / www.21cnjy.com )suggest that broadband connectivity can contribute to economic recovery，” Mr.Spiwak added.
The study has dem ( http: / / www.21cnjy.com )onstrated that there are several reasons why the Internet helps keep the jobless from quitting on their job searches such as the inexpensiveness of using the Internet to search for information about job opportunities and salaries, as well as the emotional and other types of support unemployed individuals receive by means of the Internet.The study found evidence that the unemployed are more likely to be discouraged when they do not surf the Web, and this evidence suggests that support and information obtained from the Internet significantly reduce the chances that they might feel there are no jobs, or no jobs for which they could qualify.
The study also hig ( http: / / www.21cnjy.com )hlights the benefits and importance of community broadband centers to assist those who do not have Internet access at home.
36．What do we know from the passage
A．Researchers for t ( http: / / www.21cnjy.com )he study analyzed census data of the last ten years.
B．People who l ( http: / / www.21cnjy.com )ack Internet access are less likely to quit on their job searches.
C．People can ( http: / / www.21cnjy.com )learn how to better find a job during economic crisis by using the Internet.
D．Many workers give u ( http: / / www.21cnjy.com )p looking for jobs because they don't qualify for any jobs.
37．What important insi ( http: / / www.21cnjy.com )ghts does this new study provide for policymakers
A．The Internet is an e ( http: / / www.21cnjy.com )ffective means of looking for a job for the unemployed.
B．Making the I ( http: / / www.21cnjy.com )nternet access available is beneficial to economic recovery.
C．It is necessar ( http: / / www.21cnjy.com )y to help jobless people keep on searching when job prospects are bad.

If you know the fol ( http: / / www.21cnjy.com )lowing fact, you'll understand why many people suffer from foot problems: The average person walks the equivalent of three times around the earth in a lifetime.That is enormous wear_and_tear on the 26 bones, 33 joints and more than 100 muscles that make up the foot.21*cnjy*com
In a recent surv ( http: / / www.21cnjy.com )ey for the American Podiatric Medical Association, 53 percent of respondents reported foot pain so severe that it affected their daily function.On average, people develop pain in their 60s, but it can start as early as the 20s and 30s.And usually women give care to their feet while men don't.
“A lot of people t ( http: / / www.21cnjy.com )hink foot pain is part of the aging process and accept it, and walk with pain，” said Dr.Andrew Shapiro.Though some foot problems are inevitable, their progress can be slowed.
The following quest ( http: / / www.21cnjy.com )ions will help you assess whether you should take more preventive action as you age.Do you have flat feet or high arches (足弓) Either puts feet at risk.Shoes that support the arch and heel can help flat feet.People with high arches should look for roomy shoes and softer padding (衬垫) to absorb the shock.Proper exercises also strengthen muscles supporting the foot.
Do your shoe ( http: / / www.21cnjy.com )s fit In the survey, more than 34 percent of men said they could not remember the last time their feet were measured.20 percent of women said that once a week they wore shoes that hurt, and 8 percent wore painful shoes daily.Feet flatten and lengthen with age, so if you still stick to the shoe size you wore at the age of 21，get your feet measured.
Do you walk Putt ( http: / / www.21cnjy.com )ing more mileage(里程) on your feet is the best way to exercise the muscles and keep them healthy.

Being a fashion ( http: / / www.21cnjy.com )model is a more challenging career than many people think, because you have lots of things to be aware of like maintaining your perfect figure and competing with many beautiful and attractive models.
A famous company ( http: / / www.21cnjy.com )would probably choose the perfect model for its products and if you get chosen then maybe you can consider yourself a super model.Some super models are as popular as famous actors and actresses.
Let's talk ab ( http: / / www.21cnjy.com )out qualifications to become a fashion model.You should be between 15 and 22 years old, though probably closer to 15.Models don't have careers that last as long as doctors, so agencies tend to want to invest their time in someone young.You also have to consider your height.Being tall, long legged, and thin is the most acceptable.At least 5′8″ in height and of average weight, which for a model is 108—125 pounds.These characteristics are partly aesthetic (美的) and partly practical.There are always exceptions to the rule, of course —Kate Moss is 5′7″and Gabrielle Reece is a giant 6′3″—but, in general, the closer you are to the industry criteria，the better your chances.
Aside from heig ( http: / / www.21cnjy.com )ht requirements, models are required to have good skin, great teeth, nice smile, healthy hair, and must be well dressed.Models must also be highly photogenic, able to do a variety of poses and expressions and take direction well.It is possible to have a bad skin condition but as long as you are able to keep it under control, such issues can be fixed using Photoshop.However, the clearer your complexion (肤色) is, the better.
There are many types o ( http: / / www.21cnjy.com )f models, such as editorial fashion models, commercial models, fitness models, and catalog models.Every type has its own criteria.That is why I believe that every person, who is inspired to become a model, has the chance as long as they meet the criteria.This could be your career, if that is what you want out of life.
46．What's the BEST title for the passage
A．Modeling is a challenging career
B．Height requirements for a fashion model
C．Different types of models in society
D．Things to be aware of as a model
47．If you get chos ( http: / / www.21cnjy.com )en by a famous company as a model for a certain product，________.
A. you will become a model for other companies soon
B．you are sure to be more famous than actors and actresses
C．your career as a model will be prolonged
D．it means you are competitive among all the models
48．What are ( http: / / www.21cnjy.com )the qualifications for becoming an outstanding fashion model
a．Being able to do a variety of poses and expressions
b．Having a good figure
c．Being less than 25 years old
d．Having good skin, great teeth and healthy hair
e．Having beautiful eyes and long legs
A．a，b，e B．a，b，d
C．b，d，e D．a，c，d
49．We can infer from the passage that________.
A．a person w ( http: / / www.21cnjy.com )ho is taller than others finds it easier to become a model
B．famous models are all at least 5′8″ in height
C．not all famous models are 108—125 pounds
D．people with bad skin conditions can't become a model21教育网
50．A person who wants to be a model has many chances because________.
A．there're many types of models
B．models don't need knowledge
C．few people want to do the job
D．models'skills are very simple

(2013·郴州一中高二上期中)Once a ( http: / / www.21cnjy.com ) man came to Allah (安拉) and said，“Oh Allah，I have many bad habits.Which one should I give up first？” Allah said，“Give up telling lies first and always tell the truth.”The man promised to do __13___ and went home.21教育网
At night the man w ( http: / / www.21cnjy.com )as about to go out to steal.Before setting out，he thought for a moment about the promise he made __14__ Allah.“If tomorrow Allah asks me where I have been，what should I say？Should I say that I went out to steal？No，I cannot say that.If I tell the truth，everyone will start hating me and call __15__ a thief.I would be punished for stealing.But __16___ can I lie.”21·cn·jy·com
So the man decided not ( http: / / www.21cnjy.com ) to steal that night，and gave up this bad habit.
Next day，when he was a ( http: / / www.21cnjy.com )bout to drink wine，he also remembered __17__ he had promised to Allah，so he gave up __18__ idea of drinking wine.In this way，__19__ the man thought of doing something bad，he remembered his promise to tell the truth ___20__ all times.One by one，he gave up all his bad habits.2-1-c-n-j-y

Since the gene，called ( http: / / www.21cnjy.com ) 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*cnjy*com
“We wanted to fi ( http: / / www.21cnjy.com )nd 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.【来源：21cnj*y.co*m】
Populations acro ( http: / / www.21cnjy.com )ss the 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.【出处：21教育名师】
“What we have fou ( http: / / www.21cnjy.com )nd is that things like resistance and aging tend to go hand in hand，”May said in an interview.21教育名师原创作品
May's team compared ( http: / / www.21cnjy.com )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.21*cnjy*com
May said DAF 1 ( http: / / www.21cnjy.com )6 was active 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 subtl ( http: / / www.21cnjy.com )e(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.
1．In which section may the text appear in a newspaper
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
A．Scientists Find Gene Linked to Aging
B．Population Aging Faster than Expected

Genetically modifie ( http: / / www.21cnjy.com )d(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)．21教育网
A particular conc ( http: / / www.21cnjy.com )ern 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 genetical ( http: / / www.21cnjy.com )ly 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世纪教育网版权所有
With an incre ( http: / / www.21cnjy.com )asing 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.www.21-cn-jy.com
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 【来源：21·世纪·教育·网】
A．Kenya will have the most advanced technology in the future.21·世纪*教育网
B．Crops can be modified to grow in worse natural environment.www-2-1-cnjy-com
C．Potatoes grown in wet areas can resist different kinds of insects.21教育名师原创作品
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.【来源：21cnj*y.co*m】
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.【出处：21教育名师】
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

Sharks have ( http: / / www.21cnjy.com )lived in the oceans for over 450 million years, long before dinosaurs appears .There are now about 360 species of sharks, whose size ，behavior ，and other characteristics differ widely.【版权所有：21教育】
Sharks range in size f ( http: / / www.21cnjy.com )rom the 6 inch long dwarf dog shark to 60 foot long whale shark—the world's biggest fish.The whale sharks, like two other large shark species—the basking shark and the mega mouth shark－are harmless to people because they feed on plants and small aquatic(水生的)animal.
Every year，we ca ( http: / / www.21cnjy.com )tch and kill over 100 million sharks, mostly for food and for their fins.Dried shark fins are used to make shark fin soup, which sells for as much as $50 a bowl in fine Hong Kong restaurants.Others sharks are killed for sport and out of fear.Sharks are volunterable (脆弱)to overfishing because it takes most species 10 to 15 years to begin reproducing and they produce only a few offspring.
While sharks are se ( http: / / www.21cnjy.com )en as people–eating monsters, they save human lives.In addition to providing people with food, they are helping us in cancer.They are among the few animals in the world that almost never get cancer.A research shows that chemicals extracted (提取)from shark cartiage(肋骨)have killed cancerous tumors in laboratory animals.Their highly effective immune system also allows wounds to heal quickly without becoming infected.
Sharks are neede ( http: / / www.21cnjy.com )d in the world's ocean ecosystems.Although they don't need us，we need them.We are much dangerous to sharks than they are to us.For every shark that bites a person, we kill one million sharks.

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.www.21-cn-jy.com
Cloning create ( http: / / www.21cnjy.com )s several 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.2·1·c·n·j·y
The general public' ( http: / / www.21cnjy.com )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 be a majo ( http: / / www.21cnjy.com )r 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.21*cnjy*com

A．Kyeonghee University in Korea is the first to clone animals
B．the populatio ( http: / / www.21cnjy.com )n of the world in the year 2024 will be three times more than that of today

When I was a child ( http: / / www.21cnjy.com )，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 ( http: / / www.21cnjy.com ) with 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.
