1.Intel chairman Andy Grove has decided to cut the Gordian knot of the dispute on stem cell (干細(xì)胞) research by simply writing a check.The check,which he guaranteed last week,could be for as much as 55million,depending on how many donors make gifts of between 550,000and 5,500,000,which he has promised to match.It will be made out to the University'of California-San Francisco (UCSF).
Thanks in part to such private donations,university research into uses for human stem cells,the cells at the earliest stages of development that can form any body part,will continue in California.With private financial support,the state will be less likely to lose talented scientists who would be tempted to leave the field or even leave the country as research dependent on federal (聯(lián)邦政府的)money slows to glacial (極慢的) pace.
Held back by limits President Bush placed on stem cell research a year ago,scientists are turning to labs that can carry out work without using federal money.This is awkward for universities,which must spend extra money building separate labs and keeping strict records proving no federal funds were involved.Grove's donation,a first step toward a﹩20million target at UCSF,will relieve the burden.
The president's decision a year ago to allow research on already existing stem cell lines was portrayed as a reasonable compromise (折中辦法) between scientists'needs for cells to work with,and concerns that this kind of research could lead to wholesale creation and destruction of human embryos (胚胎),cloned infants and a general disrespect for human life.
But Bush's effort to please both sides ended up pleasing neither.And it certainly didn't provide the basis for cutting edge research.Of the 78existing stem cell lines which Bush said are all that science would ever need,only one is in this country (at the University of Wisconsin) and only five are ready for distribution to researchers.All were grown in conjunction with mouse cells,making future therapeutic ( 治療的 ) uses unlikely.
The Bush administration seems bent on satisfying the small but vocal (直言不諱的) group of Americans who oppose stem cell research under any conditions.Fortunately,Groye and others are more interested in advancing scientific research that could benefit the large number of Americans who suffer from Parkinson's disease,nerve injuries,heart diseases and many other problems.

A.put an end to stem cell research
B.end Intel's relations with Gordian

73.According to Bush's decision,American universities had toD.
A.conduct the research in labs overseas
B.a(chǎn)bandon the research altogether
C.carry out the research secretly
D.raise money to build separate labs
74.We may infer from the passage that future therapeutic uses of stem cells will be unlikely unlessA.
A.human stem cells are used in the research
B.a(chǎn) lot more private donations can be secured
C.more federal money is used for the research
D.talented scientists are involved in the research
75.The reason why Bush placed limits on stem cell research was thatB.
A.his administration was financially limited
B.he did not want to offend its opponents
C.it might lead to a disrespect for human life
D.it did not promise any therapeutic value.
分析 本文主要講述美國大學(xué)對干細(xì)胞進(jìn)行研究過程中遇到的一些困難和支持.
解答 72-75 CDAB
72 C 細(xì)節(jié)題. 根據(jù)文章第三 段 Grove's donation,a first step toward a﹩20million target at UCSF,will relieve the burden.可知Grove的捐贈幫助解決了干細(xì)胞研究的爭議,故選C.
73 D 細(xì)節(jié)題. 根據(jù)文章第三 段 Held back by limits President Bush placed on stem cell research a year ago,scientists are turning to labs that can carry out work without using federal money.可知美國總統(tǒng)布什要求美國大學(xué)必修籌集資金建立單獨的實驗室,故選D.
74 A 推理判斷題. 根據(jù)文章第五 段All were grown in conjunction with mouse cells,making future therapeutic ( 治療的 ) uses unlikely.可知所有的干細(xì)胞都被種植在老鼠細(xì)胞里使得未來治療的使用不可能實現(xiàn),故選A.
75 B 細(xì)節(jié)題. 根據(jù)文章最后一段The Bush administration seems bent on satisfying the small but vocal (直言不諱的) group of Americans who oppose stem cell research under any conditions 可知布什政府好像滿足于反對干細(xì)胞研究的小的直言不諱的美國群組,故選B.
點評 做閱讀理解時要快速的瀏覽全文,把握文章主旨大意,帶著問題回到原文,尋找細(xì)節(jié)或概括相應(yīng)的答案,最后要理清作者寫作思路.
