【解析】【1】從本句后面的“...has caused mixed reactions.”可知，克隆人類胚胎已經(jīng)成功了。

【2】根據(jù)題意此處應(yīng)為“研究”，carry out research是固定搭配。

【3】make known the news是由make the news known倒裝而來，意思是“發(fā)布消息”。

【4】根據(jù)上下文可知所要表達(dá)的意思是“這不是克隆人”。

【5】根據(jù)常識(shí)可知，從事研究的應(yīng)是專家。

【6】save one's life意為“挽救某人的生命”，rescue意為“援救；營(yíng)救；挽救”，其賓語一般為人或物。

【7】從下文列舉的各種疾病可知正確答案是disease。

【8】本處意為“根據(jù)科學(xué)家的觀點(diǎn)”。

【9】在美國(guó)，省一級(jí)機(jī)構(gòu)為“州”，因此選擇states。

【10】由句中also一詞可知Bush不支持human cloning，因此選擇against。

【11】developing意為“發(fā)展；開發(fā)”；其他選項(xiàng)不符合句意。

【12】據(jù)文章的意思可知此處應(yīng)為“嬰兒”之意。

【13】克隆羊多利于1997年“誕生”了。appear在此處可引申為“誕生”之意。

【14】此題考查詞義辨析。problem通常指等待解決或決定的問題，尤其指比較困難的問題；question通常指由于對(duì)某事疑惑不解而提出問題等待回答。

【15】根據(jù)下文內(nèi)容可知要用egg一詞。

【16】此處意為“egg加入一個(gè)人的DNA后就開始生長(zhǎng)”，因此答案為after。

【17】由上文可知答案。

【18】按一般人的發(fā)育形成規(guī)律，egg開始生長(zhǎng)后應(yīng)長(zhǎng)成一個(gè)baby，而下文說it被阻止長(zhǎng)成baby，故答案為But。

【19】據(jù)題意，此處應(yīng)為“仍然；依然”。

【20】本句意為：同樣的技術(shù)已被應(yīng)用于克隆羊、牛與猴子。

【題目】People in the western state of California who are in the United States illegally can now request a driver's license. The law went into effect on January l. California is not the first American state with such a law, but it has the largest number of illegal immigrants. More than a million people began to request licenses shortly after the new state law went into effect. Among them was Christian Alvarado. Mr. Alvarado entered the United States from El Salvador eight years ago without permission from the U.S. government. Some call such people "illegal immigrants." Others call them "undocumented immigrants "

Mr. Alvarado thinks is so exciting, for be has been waiting for the license for a long time. But some are worried that their personal information will be used to find them and deport them. Armando Botello is a spokesman for the California Department of Motor Vehicles, or DMV. He says people should not be afraid, for such information will not be shared.

The new licenses are the same as licenses given to citizens except that they have the words "Federal Limits Apply". That means the license cannot be used to travel on an airplane or enter a federal building. Ana Garcia, working at the Central American Resource Center, says some illegal immigrants fear those words will be used to abuse them. Civil rights groups say the police and others

Dan Schnur , a political scientist at the University of Southern California, said that the main argument against the new law is that it rewards illegal behavior. But Professor Schnur argued that young, white Americans generally support immigration reform, including giving driver's licenses to illegal immigrants

"It's simply because they grew up a much more multicultural society than their parents or their grandparents did:" Professor Schnur says he believes the changes in beliefs about illegal immigrants that have taken place in California will spread throughout the United States.

【1】Why did the new law make Mr. Alvarado excited?

A. Because he can request a driver's license.

B. Because he became a legal immigrant of California.

C. Because he got his driving license as an illegal immigrant.

D. Because a law went into effect for the new immigrants.

【2】What is the difference of the new licenses compared to those given to citizens'?

A. The words “Federal Limits Apply” will abuse illegal immigrants

B. They can't be used to travel on an airplane or enter a federal building.

C. They can be used to act against the police and other people.

D. With the words "Federal Limits Apply", immigrants can enjoy special rights.

【3】What's the public's attitude towards the new law released on January l in California?

A. supportive B. negative

C. neutral D. Controversial
