14．Why is it so difficult to fall asleep when you are overtired？There is no one answer that applies to every individual．But many people fail to note the difference between fatigue，physical tiredness and sleepiness，the inability to stay awake．It's possible to feel"tired"physically and still be unable to fall asleep，because while your body may be exhausted，you don't feel sleepy．To fall asleep，you need enough time to relax，even if you feel fatigued．It's not so easy to simply"turn off"．According to Carl E．Hunt，director of the National Center on Sleep Disorders Research in Bethesda，Maryland，most people do not allow themselves relaxed．
Lack of sleep complicates matters even more．Experts say adults need at least 7 to 8 hours of sleep a night to function properly．When you get less sleep than that on consecutive （连续） nights，you begin to be burdened by"sleep debt"．As sleep debt increases （and functionality decreases），your body experiences a stress response and begins to release adrenaline （肾上腺素）．Now a bad cycle has been created：You experience the feeling of being more and more tired，but your body is increasingly stimulated．"Power sleeping"for more hours on weekends is only a temporary solution．"There is no substitute for getting a good night's sleep on a regular basis，"says Hunt．
Most of us，however，don't get the sleep we need．According to the 2002 National Sleep Foundation，Americans sleep an average of 6.9 hours per night during the week，and 58 percent of adults experience sleeplessness a few nights a week or more．

12．Every evening，15-year-old Rashida returns home from school，changes out of her uniform，and rushes to a neighboring farm to help her mother harvest vegetables．Her father is disabled，so the modest profit the two of them earn must cover food，clothing and other necessities for all seven children and their parents．Despite having precious little time to study，Rashida is one of the top students at her junior secondary school．But with so much responsibility on her small shoulders，she admits that it is sometimes hard for her to imagine a more promising future．
Last year，Rashida was invited to join 155 other girls at Camfed Ghana's first Girls'Career Camp，a program designed to inspire girls growing up in the country's Northern Region to dream big，and to support them to pursue those dreams．"We organized this camp because we wanted to let girls know that even if they are struggling with poverty，their lives will not be defined by limitations，"says Dolores Dickson，Camfed Ghana's Executive Director．
Over the course of five days，the camp led the junior and secondary school students through a range of experiences and career opportunities that were entirely new to them．Dr．Agnes Apusiga，a lecturer from the University of Development Studies，ran the workshop on goal-setting and career choices，describing the universities and training colleges in Ghana that could help them achieve their dreams．Participants then visited the University for Development Studies，where they toured the medical school and science labs．Another highlight was a workshop at the computer lab at Tamale Secondary School．Many of the girls had studied information technology from a book but had never before seen a computer．
"When the girls arrived at camp，they were not ambitious，because they didn't have any idea what the world held for them，"says Eugenia Ayagiba，Project Officer with Camfed Ghana．"Many had scarcely traveled beyond their own villages．"
"I t hink the most important thing that happened at the camp is th at we opened a window of hope for a group of girls coming from backgrounds of poverty，"says Eugenia．For Rashida，who has been laughed at in the past by her schoolmates because of her father's disability，the experience was important．"She told one of the camp mentors（辅导员） that when she is at school，she often feels like a misfit，and she prefers to keep to herself，"says Eugenia．"But at the camp，it was different．She made friends with girls who have similar struggles．She took part in every single activity，every single game．On the last day，she said to her mentor，‘The camp has challenged me to study hard．Now I see that there is light at the end of the tunnel．'
24．How many are there in Rashida's family？C
A．Seven        B．Eight          C．Nine              D．Ten
25．Why did the camp lead the students to visit universities and training colleges？B

B．Rashida's mentors has encouraged her a lot．
C．Rashida was sad because of her father's disability．
D．Rashida has had her new dream since the camp

19．Handshaking，the most popular way of showing friendliness，is often seen in cities and towns all over the world．It is，in fact，（25）aEuropean custom，but nobody knows exactly when this practice started．It is said that long，long ago in Europe when people met，they showed their （26）unarmed（unarm） hands to each other as a sign of goodwill．As time went on and trade in cities grew rapidly，people in cities began to clap each other's hands （27）to make（make） a deal or to reach an agreement．This practice was later changed into shaking hands among friends on meeting or leaving each other．Now"Let's shake hands on it"sometimes （28）means（mean） agreement reached．
Do the Europeans shake hands wherever they go and with whomever they meet？No，sometimes the Chinese abroad reach out their hands too often to be polite．It is really very impolite to give your hand when the meeting does not mean （29）anythingto him or her in some cases，and when the other person，especially when it is a woman，shows little interest in shaking hands with you．（30）Even if，for politeness，he holds out his unwilling hand in answer to your uninvited hand，just touch it slightly．There is generally a misunderstanding among the Chinese，which sometimes brings about unnecessary troubles，（31）thatwesterners are usually open and straightforward，while the Chinese are rather reserved in manner．But，as a matter of fact，some people in western countries are more reserved than some Chinese today．So it is a good idea to shake hands with a westerner only （32）whenhe shows interest in further relations with you．

6．You Are What You Eat
Genetic（基因的）engineering is the scientific change of the genetic material in a living organism． It allows scientists to identify specific genes，to remove them from an organism's chromosomes （染色体），improve them，analyze them，and possibly clone them，and to then reinsert the changed gene into the original organism，or a completely different organism．Unlike traditional breeding （繁殖），where a desired quality would be bred within the same species，genetic engineering can insert desired ones into organisms of different species．Wow…Did you catch that？
Genetic engineering creates many positive contributions to agriculture． For example，by genetically engineered（GE） foods，anti-cancer agents，minerals and vitamins can be increased．Improved taste，shelf life，and better transport are all possible．Also，GE plants can increase pest and bacterial resistance，therefore，making the food safe for consumers．
But some argue that the possible negative effects outweigh the positives，and critics are starting to voice their concerns．  Unlike Europe，in the United States labeling is not required on genetically engineered foods or on foods that contain genetically engineered products． Most Americans do not realize that they are，in fact，eating GE foods．
The public is also concerned about the unknown health risks．With limited understanding of genes，scientists cannot predict possible effects．Because most genes introduced into GE plants come from sources not introduced into the human body，it is impossible to know if they will cause reactions． Moreover，due to the lack of labeling if allergies develop，it will be extremely difficult to find the origin of them．
There is also a major moral question in many minds．For many，the conflict is not if it is safe or not，but it disturbs them because it is unnatural and unnecessary．We are currently producing one and a half times the amount of food needed to feed the world，yet one in seven people are starving．GE food is unnecessary，and fails to address the root of hunger． Many believe that the only people who will benefit are the corporations that produce it．
Scientists cannot foresee t．he possible effects of GE foods，yet we eat them every day without even knowing it．We already have enough food，so why create more that could be potentially harmful to us，to the Earth and to all wildlife？I think that the benefits are amazing，but until we know for sure how these foods will affect us，they are not worth the risk．

4．Robots that can chat，find misplaced glasses，draw aeroplanes and play with your children are attracting thousands of visitors during an expo in Tokyo as Japan adapts to changes in society．
Robots，such as the sound，sensitive Chapit，answer simple questions and even joke with people to help them fight loneliness and stay alert in old age．
Japan has one of the world's fastest-ageing societies and the government predicts that by 2050the proportion of people over 65will reach40percent．"Many older people in Japan live alone and have no one to talk to，"said Kazuya Kitamura representative of the expo organizer．"Communication robots accompany people and don't mind listening to the same stories over and over again．"
Matsumoto's"Personal Mobility Robot，"equipped with four cameras and a sensor to  recognize the user's centre of gravity，is designed to help elderly move around without pressing buttons，using joysticks（操纵杆）or rotating wheels as in traditional wheelchairs．
The robot can also help find misplaced glasses by identifying them with a sensor．
Other robots，such as the award-winning"DiGRO"，can support busy parents who have little time to play with their children．The robot can use the Internet to find a simple image and then draw pictures，keeping children company while parents work．
While Chapit，a relatively simple robot，managed to attract a corporate partner many researchers，such as Kiyoshi Matsumoto，a professor at the University of Tokyo，struggle to attract sponsors for more expensive projects．
"We have developed a robot that can assist many people，but we still haven't found a sponsor，"said Matsumoto，who added that the cost of the machine，if mass-produced，would be comparableto that of a car．"In the current economic environment there are few companies willing to invest in such a costly project，"he said．
