It confirms that Africa was the birthplace of humanity and thus the starting point of the original human movements.6. Their genes show the Khoisan may be a ve

6、ntelligence had been identified, but to date the results have yet to be confirmed.2. They seem to think that building a new road will improve the traffic problem, but in effect, it will make it worse.Exercise IV (1)3. The scientists created nothing less than the first genetic map of the world.4. As

The best way to lose weight is proper diet in combination with regular exercise.Exercise IV (2)6. Many women in the city have taken low-paid, so-called part-time work in addition to their child-re

This story is more than interesting; it is educational, as well. Exercise VIII (1)4. Hepworth is much more than a filmmaker; he had learnt to find stories tha

Exercise VIII (2)What was needed was nothing less than a new industrial revolution.This is nothing less than a call to arms to restor

12、e the vitality of the American dream. 3. Their dream was nothing less than a revolutionary project to bring computers and ordinary people together. Exercise IX (1)The experience of sightseeing in the wonderful island is nothing less than exciting and I am moved to tears.5. He was much concerned that

13、 she should not be tired, or bored and he wanted to make sure that the holiday would be nothing less than perfect for her. Exercise IX (2)1. We have received three anonymous letters from Palestine to date, in addition to one suspicious package. Their dream was nothing less than a more equal society

His fate in the last election, she said, would serve as a reminder to all politicians that popularity does not last. 5. In effect, only hard work in combination with pro

15、per methods will always give you an advantage over others in study. 6. Technology itself, and its effective use, is not to be confined to the traditional science subjects. Exercise X (3)Exercise X (4)Since the truth of this report was discounted, I was not in a position to publish it for you. 8. Man

16、y software companies have adapted general programs to the new operating system. 它對人類在基因層面上的差異作了迄今為止最為它對人類在基因層面上的差異作了迄今為止最為廣泛的調查。廣泛的調查。實際上，那種認為某一種群比另一種群的基因更實際上，那種認為某一種群比另一種群的基因更優越的理論是毫無科學根據的。優越的理論是毫無科學根據的。 Exercise XI (1)3. 為了確保種群的為了確保種群的“純正純正”，這項研究將對象限定，這項研究將對象限定于其目前的生活區域仍與于其目前的生活區域仍與1492年以來相同的那些年以來

17、相同的那些群體，即在來自歐洲最初的大規模遷移之前。這群體，即在來自歐洲最初的大規模遷移之前。這實際上就是一幅真實的哥倫布駛向美洲時期的世實際上就是一幅真實的哥倫布駛向美洲時期的世界人口基因分布圖。界人口基因分布圖。4. 我們眼中看到的人種差異，例如歐洲人與非洲人我們眼中看到的人種差異，例如歐洲人與非洲人的差異，主要是人類從一個大陸向另一個大陸遷的差異，主要是人類從一個大陸向另一個大陸遷移時為適應氣候所產生的。移時為適應氣候所產生的。Exercise XI (2)Exercise XI (3)5. 結結合對遠古人骨的研究，這一圖譜證實了非洲是合對遠古人骨的研究，這一圖譜證實了非洲是人類的誕生地，

18、因而也是人類遷移的始發地。人類的誕生地，因而也是人類遷移的始發地。6. 這些發現，再加上現代非洲人與非非洲人之間的這些發現，再加上現代非洲人與非非洲人之間的巨大基因差距，說明了從非洲人種群開始的分支巨大基因差距，說明了從非洲人種群開始的分支是人類家譜上最早的分支。是人類家譜上最早的分支。 Exercise XI (4)7.7. 除了揭示人種的起源以外，基因信息也是醫學界除了揭示人種的起源以外，基因信息也是醫學界可用的最新原料。醫學界希望能用人類脫氧核糖可用的最新原料。醫學界希望能用人類脫氧核糖核酸（核酸（DNADNA）制成特別的蛋白質，這些蛋白質具有制成特別的蛋白質，這些蛋白質具有某種抗病藥物

19、的價值。某種抗病藥物的價值。8. 8. 保護土著人權益活動家們擔心科學家可能會利用保護土著人權益活動家們擔心科學家可能會利用土著人謀利：從當地人血樣中提取的基因物質可土著人謀利：從當地人血樣中提取的基因物質可被用于商業目的，卻不給被用于商業目的，卻不給DNADNA提供者以足夠的報酬。提供者以足夠的報酬。 1. C 2. B 3. A 4. D 5. A 6. C 7. D 8. C 9.
