The Tough Grass that Sweetens Our Lives
Sugar cane was once a wild grass that grew in New Guinea and was used by local people for roofing their
houses and fencing their gardens. Gradually a different variety evolved which contained sucrose(蔗糖)and
was chewed on for its sweet taste.Over time,sugar cane became a highly valuable commercial plant,grown
throughout the world.___________(46)
Sugar became a vital ingredient in all kinds of things, from confectionery(糖果点心)to medicine,
and,as the demand for sugar grew,the industry became larger and more profitable._________(47)Many
crops withered(枯萎)and died,despite growers'attempts to save them,and there were fears that the health
of the plant would continue to deteriorate.
In the 1960s,scientists working in Barbados looked for ways to make the commercial species stronger
and more able to resist disease.They experimented with breeding programmes,mixing genes from the wild
species of sugar cane,which tends to be tougher,with genes from the more delicate,commercial type.
_________(48)This sugar cane is not yet ready to be sold commercially,but when this happens,it is
expected to be incredibly profitable for the industry.
___________(49)Brazil,which produces one quarter of the world's sugar,has coordinated an interna-
tional project under Professor Paulo Arrudo of the Universidade Estaudual de Campinas in Sao Paulo.Teams
of experts have worked with him to discover more about which parts of the genetic structure of the plant are
important for the production of sugar and its overall health.
Despite all the research,however,we still do not fully understand how the genes function in sugar
cane.__________(50)This gene is particularly exciting because it makes the plant resistant to rust,a dis-
ease which probably originated in India,but is now capable of infecting sugar cane across the world.Scien-
tists believe they will eventually be able to grow a plant which cannot be destroyed by rust.
A:The majority of the world's sugar now comes from this particular commercial species.
B:Unfortunately,however,the plant started to become weaker and more prone to disease.
C:Eventually,a commercial plant was developed which was 5 percent sweeter than before,but also much stronger and less likely to die from disease.
D:Since the 1960s,scientists have been analysing the mysteries of the sugar cane's genetic code.
E:One major gene has been identified by Dr Angelique D'Hont and her team in Montpelier,France.
F: Sugar cane is now much more vigorous and the supply of sugar is therefore more guaranteed.

A解析:前一句话提到,甘蔗成了一种非常有价值的商业作物,在世界范围种植起来。因此这 句话应该是讲种植甘蔗成了获得糖的主要来源。故选A。
前面一句说由于对糖需求的增加,种植甘蔗这一行业也得以壮大并且获利更多。后面 一句提到,很多甘蔗作物枯萎并且死掉,尽管种植者试图去救治它们,大家还是担心甘蔗的健 康状况会持续恶化。所以中间的句子应该是承接的转折句。故选B。
前面讲到,科学家们正在寻找一种能使商业型甘蔗更强壮、抗病性更高的方法。他 们实验把野生甘蔗的基因和商业用甘蔗的基因相结合。后面一句讲这种类型的甘蔗还没有 开始商业化地出售。由此可知,中间的句子应该是讲将研发的这种商业型甘蔗的特点。故 选C。
该句位于段首应该是主题句。根据后面的内容该段主要讲,巴西这个甘蔗生产大国和 一位教授合作来研究在甘蔗的基因结构中,哪一部分对生产糖最重要以及甘蔗整体的健康状 况。故选D,意思是“从二十世纪六十年代起,科学家们就开始分析甘蔗基因的神秘性。”
前一句讲,尽管做了这么多的研究,但是我们仍不清楚甘蔗的基因情况。后一句开头说“这一基因之所以独特地存在是因为······”,这里提到的这一基因(this gene)应该是新发现 的。故选E。第6部分:完形填空

US Blacks Hard-hit by Cancer
Death rates for cancer are falling for all Americans,but black Americans are still more likely to die of
cancer than whites,the American Cancer Society said Monday.
In a special report on cancer and blacks, the organization said blacks are usually diagnosed with cancer
later than whites,and they are more likely to die of the disease.
This could be because of unequal access to medical care,because blacks are more likely to have other
diseases like diabetes as well,and perhaps because of differences in the biology of the cancer itself,the report added.
"In general,African Americans have]ess likelihood of surviving five years after diagnosis than whites for
all cancer sites and all stages of diagnosis,"the report said.
"In describing cancer statistics for African Americans,this report recognizes that socioeconomic dispari-
ties and unequal access to medical care may underlie many of the differences associated with race."
The Cancer Society said blacks should be encouraged to get check-ups earlier,when cancer is more
treatable,and it said more research was needed to see if biological differences play a role.
Since 1992,cancer death rates among black Americans_______.
A:have been going up and down
B:have remained stable
C:have increased
D:have fallen
Something Men Do Not Like to Do
Eric Brown hates shopping."It's just not enjoyable to me,"said the 28-year-old

Goal of American Education
Education is an enormous and expensive part of American life.Its size is matched by its variety.
Differences in American schools compared with those found in the majority of other countries lie in the
fact that education here has long been intended for everyone一not just for a privileged elite.Schools are ex-
pected to meet the needs of every child,regardless of ability,and also the needs of society itself. This means
that public schools offer more than academic subjects.It surprises many people when they come here to find
high schools offering such courses as typing,sewing,radio repair,computer programming or driver training,
along with traditional academic subjects such as mathematics,history,and languages.Students choose their
curricula depending on their interests,future goals,and level of ability. The underlying goal of American edu-
cation is to develop every child to the utmost of his or her own possibilities,and to give each one a sense of
civic and community consciousness.
Schools have traditionally played an important role in creating national unity and"Americanizing"the
millions of immigrants who have poured into this country from many different backgrounds and origins.
Schools still play a large role in the community,especially in the small towns.
The approach to teaching may seem unfamiliar to many,not only because it is informal,but also
because there is not much emphasis on learning facts.Instead,Americans try to teach their children to think
for themselves and to develop their own intellectual and creative abilities.Students spend much time,learning
how to use resource materials,libraries,statistics and computers.Americans believe that if children are
taught to reason well and to research well,they will be able to find whatever facts they need throughout the
rest of their lives.Knowing how to solve problems is considered more important than the accumulation of
This is America's answer to the searching question that thoughtful parents all over the world are asking
themselves in the fast-moving time:"How can one prepare today's child for a tomorrow that one can neither
predict nor understand?"
Which of the following best states the feature of American education that makes it different from education in other countries?
A:The large number of its schools.
B:The variety of the courses offered in its schools.
C:Its special consideration given to immigrants.
D:Its underlying goal to develop every child's abilities to the fullest extent.
Battle Hymn of Tiger Mother
In general,I think Western parenting gives children too much freedom at too young an age.The average American child spends almost 70 percent more time watching television than attending school.In the recent PISA international tests,the US came out an embarrassing 23rd in science and 34th in math一with Shanghai children ranked No 1.Western children have alarming rates of alcohol and drug abuse and teenage pregnancy,too.On the other hand,American universities continue to be the envy of the world,and the US excels at teaching creativity,innovation and leadership.
What are the lessons for China then?Here are a few things China may be able to learn from the West.
First,while children in the West have too much choice,their counterparts in China may have too little.In between school,tutoring and lessons,many Chinese children work nonstop,getting little opportunity to have fun with friends,explore on their own and discover what they truly enjoy.What I learned is that as children grow up,parents should listen to their choices more carefully and gradually
give them more freedom to pursue their own passions.
Second,Chinese parents should pay more attention to their children's individual personalities. Every child is different. So depending on children's natural predispositions(秉性),different career paths will make them happy. Some people may find it more fulfilling to become a photographer or fashion designer instead of a doctor. If Chinese parents become more open-minded in what they consider"success",it may help lessen the intense competition and pressure that many Chinese children feel.
Finally,Chinese parents are good at getting their children to memorize,practice and drill一skills I believe the West needs more of一but they should also find ways to encourage creativity and initiative.My daughters were lucky because my husband taught them the value of independent thinking. He always asked"why".Just because someone told you so,how do you know it's right?
Parenting is the hardest job I've ever had.When Lulu rebelled and I began questioning everything I'd done.I feel very lucky that I adjusted in time一today my daughters and I are close friends一and I wanted to share my story with other mothers,because we are all struggling with the same problem:how can we raise happy,strong,self-reliant children?
The author has more than one children.
C:Not mentioned
