Present at the meeting were Professor White, Professor Smith and many other guests.出席会议的有怀特教授，史密斯教授和许多其他客人。

10．We must do as much as we can to make our community better and more beautiful.

我们必须尽力使我们的社区更好、更美丽。

as…as we can是一个比较状语从句，意思为“尽可能，尽力”，相当于as…as possible, to make our community better and more beautiful是不定式短语，在句中作目的状语。

注意：情态动词can, could和不定式不属于同一个意群。由例句可以看出，不定式为主句的一部分，作目的状语；而can, could为状语从句谓语动词的一部分，其后已承前省略了动词原形，所以不要再把can, could与不定式混同为“情态动词后接动词原形”。如：

I’ll do as much as I can to help him.我将尽我所能来帮助他。

（can之后已省略动词原形do，to help him作目的状语）

11．We should believe in our family, our people, our teachers and our leaders.

13．Each time we celebrate a festival it changes a little……

每次庆祝节日都会有一点儿变化，……

each time在这里是名词短语作连词，引导一个时间状语从句。再如：

Each time I saw him, he was busy with his work.

14．Many festivals around the world are celebrated around the same time.

世界上许多节日大约都在同一时间庆祝。

注意：第一个around相当于in，第二个around相当于at about

15．Our ancestor celebrated the birth of a son or a daughter by giving away red eggs.

3. When I got my master’s degree, I wanted to return home but couldn’t find a company where I could use what I had learnt. 当我获得硕士学位时，我想回到家乡，可是我没能找到学有所用的公司。

类文阅读针对性练习(16分，20分钟)

Farmers could grow more rice and shaky Internet communications could work better some day, thanks to prize-winning discoveries by teenage scientists showed at a national science fair on Monday.

High-school scientists from across the United States showed off word in genetics (遗传学), molecular biology, mathematics and other fields that judges said rose to the professional level.

“It just blows me away. They’re all just unimaginable, ”said Joel Spencer, a New York University professor who served as a judge at the Siemens Westinghouse Competition in Math, Science and Technology.

Research done by finalists in the nationwide competition could lead to faster Internet speeds, more effective antibacterial drugs and better energy conservation. One team researched black holes in outer space, while another examined more than 700 fossils to better understand why dinosaurs died out.

Juliet Girard and Roshan Prabhu won a $ 100, 000 scholarship for their work proving genes(基因) that help some strains of wild rice flower earlier than others.

Drawing on a database(数据库) that described the genetic makeup of rice, the two students, from Jersey City, New Jersey, identified two genetic segments (sections) that directed wild rice to blossom an average of 10 days earlier than the ordinary short-grain rice that feeds much of the world.

Their discovery could allow genetic engineers to develop a new strain that would take less time to reach maturity, allowing farmers to produce more and extending the growing region into colder climates.

Steven Bymes of Lexington, Massachusetts, took the top individual prize for his theory describing outcomes in a two-player game called Chomp.

Several said they planned to publish their findings in famous professional magazines.

1.What made the university professors surprised was that .

A.high-school students did very well in all scientific fields

B.they had never thought of these things when they were young

C.the work of the high-school students was of high quality and reached the professional level

D.high-school students have found out why dinosaurs died out

2.Which of the following is true?

A.Two students discovered the way of growing more rice and growing rice in colder climates.

B.What the two students discovered about the genetic makeup of rice may lead to an important development in agriculture.

C.Steven Bymes took the top prize at the national science fair on Monday.

D.Several students planned to write more articles in some professional journals.

3.What is this report mainly about?

A.Farmers can grow more rice and shaky Internet communications can work better after the competitions are held.

B.Some high-school students have become professional scientists.

C.High-school students can make great contributions to the world in many fields just like adult scientists.

D. A national science fair made scientists greatly surprised.

Scientists have uncovered the exact difference between man and mouse.

Teams of scientists from around the world will publish today the draft(草图)genome(基因组)of the mouse, which enables them for the first time to compare another mammal’s entire DNA directly with that of humans.

The similarities are far greater than the differences- man and mouse share a common ancestor that lived more than 70 million years ago-which has allowed scientists to find treatments for a good many human diseases.

British members of the project say the draft mouse genome, published in the journal Nature, has provided the “phrase book” for scientists to translate the language of the human genome.

“The entire biomedical research community can for the first time fully use this resource to deal with human diseases. They will now have powerful tools that will serve them for many years to come, ” said Dr Jane Rogers, head of sequencing at the Wellcome Trust Sanger Institute in Cambridge, which did 20 percent of the work.

Comparisons show almost every gene in the mouse has a corresponding (对应的)gene in humans 99 percent similarity that should help to find how each human gene works. Already the work has been able to show that man and mouse each have about 30, 000 genes yet only 300 or so are unique to either species, increasing the value of the lab mouse as a “model” for human genetics.

This is an extraordinary milestone. For the first time we have an opportunity to see ourselves in an evolutionary(进化的)mirror. The mouse genome stands for a very important chapter in the lab notebook of evolution By taking away genes to create sick mice, scientists have been able to reproduce a number of human disorders. Knowing the entire genomes of humans and mice will enable them to employ the technique more widely, leading to a rapid development in the understanding of illnesses.

4.Scientists have found that .

A.men and mice are actually the same kind of animal

B.mice are actually the ancestors of human beings

C.the genome of the mouse is the same as that of humans

D.humans and mice most probably have developed from the same ancestor

5.The importance of the discovery lies in the fact that .

A.man has finally found his true ancestor

B.it will be easier for people to find the causes of human diseases and cure them

C.it has enabled the scientists to compare human DNA with that of another mammal

D.it makes it possible for man to understand the complicated language of his genome

6.The word “unique” in the sixth paragraph probably mean .

A.having no like of equal
