1．likely, possible 与probable

上海龙凤1314（1）三者均表可能性，但意思有别。possible指客观上有可能性，但往往含有希望很小的意味；probable比possible可能性稍大，有“较为可能、大概”，指有实际依据；likely是从外表迹象判断有可能发生的事。 eg：

It’s possible, though not probable, that he will come tomorrow.

他明天可能来，但也不一定准来。

She is likely to ring me tonight. 今晚她很可能给我来电话。

上海龙凤1314（2）possible 不能用人作主语。possible 常用于下列句型：

上海龙凤1314It is possible to do sth. It is possible for sb. to do sth.

It is possible that … eg:

上海龙凤1314Is it possible to say so?可能这样说吗？

It is possible for me to do it. 我可能做那件事。

（3）probable 也不能用人作主语。一般只用于下面句型中：

It is probable that … eg:

It is probable that he will come. 他很可能要来。

（4）likely 既可用人作主语，也可用物作主语。通可用于“It is likely that …”句型中。 eg:

上海龙凤1314He is likely to come. = It is likely that he will come.

上海龙凤1314他可能要来。但不能说：It is likely for him to come.

（5）impossible, improbable, unlikely 用法与上述类似。

2．catch, grasp, seize 与snatch

catch是普通用语，用“设法抓住，捉住”的意思； grasp表示牢牢地“抓住”；seize指“突然用力抓住使不逃脱”；snatch 表示迅速的拉扯动作、出其不意地“抓取”。 eg:

上海龙凤1314The police caught the thief as he ran. 小偷逃跑时被警察抓住了。

上海龙凤1314He grasped his gun and rushed out. 他抓起枪就冲了出去。

He seized the gun from the enemy soldier. 他从敌人士兵手中夺过了枪。

政府成立工作组调查此问题。

上海龙凤1314（2）in the late 1990s 又可写成in the late 1990’s 二十世纪九十年代末

in the early 1980s 二十世纪八十年代初

上海龙凤1314（3）hi-tech= high technology 高科技，高技术

上海龙凤13143． 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。

（1）本句是一个复合句。When I got my master’s degree 为时间状语从句，修饰主句谓语动词wanted。wanted和couldn’t find为并列谓语动词，由并列连词but连接。where I could use what I had learnt为定语从句，修饰先行词company。what I had learnt 为宾语从句。

上海龙凤1314（2）a master’s degree 硕士学位 a doctor’s degree 博士学位

上海龙凤1314a bachelor’s degree 学士学位

又如：Master of Arts 文学硕士 Doctor of Law 法学博士

上海龙凤1314类文阅读针对性练习（16分，20分钟）

A

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.

上海龙凤1314Research 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.

上海龙凤1314Their 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.

上海龙凤1314Several 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

上海龙凤1314B．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

上海龙凤1314D．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.

上海龙凤1314C．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.

上海龙凤13143．What is this report mainly about?

上海龙凤1314A．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.

上海龙凤1314D． A national science fair made scientists greatly surprised.

B

上海龙凤1314Scientists have uncovered the exact difference between man and mouse.

上海龙凤1314Teams 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.

上海龙凤1314The 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
