1、Module 5 Cloning.阅读理解A recent announcement by scientists that they have successfully cloned the first human embryo has caused much debate and has shocked many people around the world.On the one hand，some scientists point out that if you clone an embryo，you can produce valuable tissues and organs tha

2、t could be used to save human lives.On the other hand，many people，including some scientists，disagree and fear that if mankind interferes with (干涉) nature in this way，they may be on their way to producing a reallife Frankensteins monster.Cloning is producing an exact copy of a plant or an animal usin

3、g its cells.The first mammal to be cloned successfully from an adult cell was Dolly the sheep.She was born in 1996 and died in early 2003，at a much younger age than normal.When she was born，many people were angry because they thought cloning would create more diseases in the animal world.However，in

4、general the scientists were praised for their wonderful scientific breakthrough.The Scottish scientist who created Dolly，Ian Wilmut，is shocked that some scientists are now considering cloning human beings.Although he researches cloning，he has never thought of creating copies of humans.Instead，he thi

5、nks the scientists should concentrate on creating new tissues and organs that could eventually be used to cure diseases like cancer.However，some people consider that cloning human embryos with the intention of destroying them shows no respect for human lives.While cloning human embryos is illegal in

6、 many countries，some scientists are already pushing ahead with the research so as to deliver a cloned human baby.Severino Antinori，an Italian doctor，is one of the leaders in this field of research.He has declared that he wants to be the first to clone a human being.In China，scientists have focused t

7、heir efforts on cloning animals，as well as stem cells to be used in medical research.China has succeeded in producing clones of cows and goats，and continues to research ways in which cloning can benefit mankind.1Which of the following statements about cloning is TRUE according to the passage?AClonin

8、g technology can only be applied to animals.BA cloned animal can live longer than a normal one.CPeople all over the world are happy about the birth of Dolly.DCloning can produce valuable tissues and organs to cure human diseases.答案：D解析：细节理解题。根据第一段第二句话可知D项正确。根据第二段首句可知A项错误。从多莉(Dolly)的例子可知克隆的动物不如正常的动物寿

9、命长，故B项错误。C项与原文第二段第四句话相悖。2The reasons why some people disagree with cloning include the following EXCEPT that .Acloning may produce a reallife Frankensteins monsterBcloning might create more diseases in the animal worldCcloning cant help those who want to clone their dead childrenDcloning human embry

10、os shows no respect for human lives答案：C解析：细节理解题。文中提到人们反对克隆技术的原因包括A、B和D三项。而根据第四段第一句“尽管克隆人类胚胎目前在很多国家是非法的，但是有些科学家已经开始加紧研究，以便降生一个克隆的人类婴儿”，并不能判断是否能够克隆出人们死去的孩子，而且这也不是人们反对克隆的原因，故答案为C项。3Who is in favor of cloning human beings?AIan Wilmut.BSeverino Antinori.CThe author. DThe Chinese scientists.答案：B解析：细节判断题。根

11、据文章倒数第二段第二句可知答案为B项。4What can be inferred from the last two paragraphs?AIf we interfere with nature，we will change the world to be what we want.BIt is impossible to clone babies for women who cannot have ones.CCloning human beings is illegal in many countries，so no scientists want to do so.DWhether c

12、loning human embryos is legal or not remains a matter of debate.答案：D解析：推理判断题。通过最后两段，我们可以推断出虽然克隆人在很多国家还不被认可，但是有些科学家已经开始了这方面的研究。对于克隆人是否合法现在还是一个有争议的问题。故选D项。.七选五For people with thousands of pages to read, speed reading seems like manna (甘露) from heaven.In addition, speed reading helps lighten the load o

13、f information you have to absorb since it provides a filter that you can use in screening all bits of information before you approach it. 1 Examining how much information you need will help you identify how you should read a certain document to maximize your learning and comprehension.Thorough readi

14、ng may no longer be necessary in some cases, such as when you only need an outline of a certain document.Another skill that can ease the burden of a reader is the ability to read words in blocks.Make sure you do not spend too long on a certain block. 2 This will also make reading less tiresome and b

15、oring.To master this important skill, you have to practice reading more and more words in a certain block at a time.A suggestion shared by some experts regarding this step is to increase the distance between you and the document you are reading.If you can read more and more words in one block, you c

16、an cut down on the time it usually takes you to read a certain text and you will be able to read more in a shorter period.Readers should also practice reducing the number of times they go back to previous sections or blocks.Using a pointer such as the tip of a pencil or pen can also help to make the

17、 flow of your reading smoother and faster. 3 Thus, your speed in reading will largely depend on the speed of the movement of your pointer.If you still find yourself confused about the topic even after you have finished reading the document, do not reread right away.Rereading immediately will just le
