7.When asked to explain         made her remain so young,she began to teil us her secret.(  )
A.what it was thatB.that what was it
C.it was what thatD.what was it that

分析 当被要求解释到底是什么让她保持这样年轻时,她开始告诉我们她的秘诀.

解答 答案:A
题干中made her remain so young是作explain的宾语,是一个宾语从句;从句中made缺少主语,要用连接代词;宾语从句中,从句要放的连词后且要用陈述句语序;it was that构成强调句型,对what进行强调,不影响句子结构.故选A.

点评 在句子中起名词作用的各种从句统称为名词性从句.根据它们在句中的语法作用,这类从句又可分为主语从句、同位语从句、表语从句和宾语从句. 本题中what在宾语从句中起连接作用,同时又充当了从句的主语.

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.'

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.
