二、如何聽的建議

如本單元聽力部分題干中涉及到三位從事科學(xué)探索的著名人物，聽力內(nèi)容則應(yīng)重點(diǎn)注意他們的 achievements。

二、同、近義詞辨析
1．likely, possible 與probable
（1）三者均表可能性，但意思有別。possible指客觀上有可能性，但往往含有希望很小的意味；probable比possible可能性稍大，有“較為可能、大概”，指有實(shí)際依據(jù)；likely是從外表跡象判斷有可能發(fā)生的事。 eg：
It’s possible, though not probable, that he will come tomorrow.
他明天可能來，但也不一定準(zhǔn)來。
She is likely to ring me tonight. 今晚她很可能給我來電話。
（2）possible 不能用人作主語。possible 常用于下列句型：
It is possible to do sth. It is possible for sb. to do sth.
It is possible that … eg:
Is it possible to say so?可能這樣說嗎？
It is possible for me to do it. 我可能做那件事。
（3）probable 也不能用人作主語。一般只用于下面句型中：
It is probable that … eg:
It is probable that he will come. 他很可能要來。
（4）likely 既可用人作主語，也可用物作主語。通可用于“It is likely that …”句型中。 eg:
He is likely to come. = It is likely that he will come.
他可能要來。但不能說：It is likely for him to come.
（5）impossible, improbable, unlikely 用法與上述類似。

catch是普通用語，用“設(shè)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脫”；snatch 表示迅速的拉扯動(dòng)作、出其不意地“抓取”。 eg:
The police caught the thief as he ran. 小偷逃跑時(shí)被警察抓住了。

（1）本句是一個(gè)復(fù)合句。When I got my master’s degree 為時(shí)間狀語從句，修飾主句謂語動(dòng)詞wanted。wanted和couldn’t find為并列謂語動(dòng)詞，由并列連詞but連接。where I could use what I had learnt為定語從句，修飾先行詞company。what I had learnt 為賓語從句。
（2）a master’s degree 碩士學(xué)位 a doctor’s degree 博士學(xué)位
a bachelor’s degree 學(xué)士學(xué)位
又如：Master of Arts 文學(xué)碩士 Doctor of Law 法學(xué)博士

（1）此句為復(fù)合句。it為形式賓語，代表that引導(dǎo)的賓語從句。
（2）rely on/upon信賴，依賴 eg: He can always be relied upon or help. 他的幫助是永遠(yuǎn)可依賴的。
You may rely on my early arrival. 你放心好了，我會(huì)早到的。

類文閱讀針對(duì)性練習(xí)（16分，20分鐘）

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 （遺傳學(xué)）, 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（數(shù)據(jù)庫） 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（草圖）genome（基因組）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 （對(duì)應(yīng)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（進(jìn)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.
