Huge 【2】 (quantity) of carbon dioxide produced by burning fuels like coal, natural gas and oil 【3】 (result) in the "greenhouse effect".

【3】have resulted

【4】increasing

【5】trapped

【6】But

【7】trend

【8】opposed

【9】consequences

【10】which

【解析】

【1】to 考查固定結(jié)構(gòu)。句意：所有科學(xué)家都同意是人類活動導(dǎo)致全球變暖這一觀點。subscribe to意為“同意；訂閱”。故此空填to。

【2】quantities huge quantities of大量的。

【3】have resulted 考查時態(tài)。句意：燃燒煤、天燃?xì)夂褪彤a(chǎn)生的大量二氧化碳已經(jīng)導(dǎo)致了溫室效應(yīng)。由句意可知這里用現(xiàn)在完成時，故填have resulted。

【4】increasing 考查動名詞。句意：所有科學(xué)家也認(rèn)同二氧化碳的水平持續(xù)增加。Keep on doing持續(xù)做某事，故這里用increasing。

【5】trapped 考查過去分詞。句意：因此更多的熱能有可能被困在大氣層中。根據(jù)句意可知這里用trapped。

【6】But 考查連詞。句意：但是科學(xué)家對這種現(xiàn)象有不同的態(tài)度。這里用連詞but表示轉(zhuǎn)折。

【7】trend 考查名詞。句意：一方面，一些科學(xué)家認(rèn)為，氣溫增加5度的趨勢會是一個大災(zāi)難。這里作賓語，而且前面有the修飾，故用名詞形式。

【8】opposed 考查固定結(jié)構(gòu)。句意：另一方面，一些人反對這個觀點。be opposed to反對。

【9】consequences 句意：幾乎沒有壞的環(huán)境影響。consequences意為“結(jié)果，后果”。

【10】which 考查定語從句。句意：相反，他們認(rèn)為更多的二氧化碳對植物，莊稼以及很多的動物是有利的，這會讓人們的生活更好。這里構(gòu)造了非限制性定語從句，用which指代上句并在定語從句中做主語。

Make a Better Impression

【題目】Once when I was facing a decision that involved high risk, I went to a friend. He looked at me for a moment, and then wrote a sentence containing the best advice I’ve ever had: Be bold and brave―and mighty(強大的)forces will come to your aid.

Those words made me see clearly that when I had fallen short in the past, it was seldom because I had tried and failed. It was usually because I had let fear of failure stop me from trying at all. On the other hand, whenever I had plunged into deep water, forced by courage or circumstance, I had always been able to swim until I got my feet on the ground again.

Boldness means a decision to bite off more than you are sure you can eat. And there is nothing mysterious about the mighty forces. They are potential powers we possess: energy, skill, sound judgment, creative ideas―even physical strength greater than most of us realize.

Admittedly, those mighty forces are spiritual ones. But they are more important than physical ones. A college classmate of mine, Tim, was an excellent football player, even though he weighed much less than the average player.“In one game I suddenly found myself confronting a huge player, who had nothing but me between him and our goal line,” said Tim.“I was so frightened that I closed my eyes and desperately threw myself at that guy like a bullet(子彈)―and stopped him cold.”

Boldness―a willingness to extend yourself to the extreme―is not one that can be acquired overnight. But it can be taught to children and developed in adults. Confidence builds up. Surely, there will be setbacks(挫折)and disappointments in life; boldness in itself is no guarantee of success. But the person who tries to do something and fails is a lot better off than the person who tries to do nothing and succeeds.

So,always try to live a little bit beyond your abilities―and you’ll find your abilities are greater than you ever dreamed.

【1】 Why was the author sometimes unable to reach his goal in the past?

A.He faced huge risks.

B.He lacked mighty forces.

C.Fear prevented him from trying.

D.Failure blocked his way to success.

【2】 What is the implied meaning of the underlined part?

A.Swallow more than you can digest.

B. Develop more mysterious powers.

C.Act slightly above your abilities.

D. Learn to make creative decisions.

【3】 What can be learned from Paragraph 5?

A.Confidence grows more rapidly in adults.

B.Boldness can be gained little by little.

C.Repeated failure creates a better life.

D. Trying without success is meaningless.

【4】What is the author’s purpose in writing this passage?

A.To encourage people to be courageous.

B.To advise people to build up physical power.

C.To tell people the ways to guarantee success.

D.To recommend people to develop more abilities.

【題目】 閱讀理解

閱讀下列短文，從每題所給的四個選項（A、B、C和D）中，選出最佳選項。

Net Library is a library that lends out digital books. It treats a digital book like a paperback copy. It charges libraries per book per copy and gives publishers a cut of the total income.

From the consumer’s point of view, this means that if more than five people want the latest Danielle Steel romance novel, other people who request that book will get a message saying the title is unable to get.

Many publishers seem to have embraced its model. More than 350 publishers gave the company rights to hand out their digital works, and McGraw-Hill Corporation and Houghton Mifflin Corporation have put money into the company. The California public libraries and about 1,800 others across the US are trying out the Net Library service.

Some librarians criticize the Net Library model. Stanford University librarian Michael Keller argues that the company is creating an unnatural fear of digital works, which is contrary to the ideas of the Internet.

Keller and some other librarians argue for the e-book vision set forth by Brary. Brary is starting a service that lets us users read books for free.

But it will charge about 25 cents a page when a person tries to point out material or copy and taste it into a different file or tries to download a copy onto a computer.

Christopher Warnock, chief executive of Brary, believes most consumers won’t want to buy entire books, only the parts that interest them.

“There is not really a lot of good owning an electronic file and having to store it and manage it. It doesn’t make sense,” he said.

【1】How do publishers get money from the Net Library?

A．They get money from selling their books to the Net Library

B．They get money from the readers．

C．They get money by cutting the cost of the books．

D．They share the money with Net Library．

【2】The underlined word “embraced” in the third paragraph means

A. tried out something hard

B. held something tightly

C. disliked something badly

D. taken something willingly

【3】What does the last paragraph mean?

A. Net Library is not a good way for the consumers．

B. There is no need for consumers to have a whole book．

C. Brary is not a good library for the consumers．

D. It’s reasonable to charge the consumers money for copying some pages．
