Question

【題目】 On Nov.20, a police dog training center in Beijing welcomes six new members. They are all cloned（克�。�dogs, China Daily reported.

The dogs were born in August. They were cloned from two police dogs who have helped police solve murder cases（謀殺案）.

Early this year, scientists took some cells from the dog's skin and created cloned embryos（胚胎）. Then they put the embryos into three mother dogs. One mother gave birth to four dogs, while the other two gave birth to one each. The cloned dog's DNA is a 99% match with their "fathers".

It is hoped that the cloned dogs will be as talented as their "fathers" because they are cloned. The cloned dogs are just four months old, but have already shown that they're brave and aggressive（有攻擊力的）, as well as have great memories, according to Ma Jinlei, a police officer at the center. It will take less time and money to train them.

Kunxun, China's first cloned dog, joined the police in Kunming in March. The world's first cloned dog was born in South Korea in 2005.

However, animal cloning has long been a hot topic. The world's first cloned animal, Dolly the sheep, died at the age of 6 in 2003, about six years earlier than most sheep. Some people have questioned whether cloning technology is safe.

In addition, some people worry that cloning technology may be used on humans someday and therefore may raise some problems. Can we call cloned human a real human?

文章介紹了北京一家警犬培訓中心迎來6名新成員——克隆犬，并且還介紹了這些狗的克隆過程，以及在克隆方面的世界上一些案例，以及人們擔心克隆被應用在其他不好的方面從而引發(fā)一些問題。

【1】細節(jié)理解題。根據文中It is hoped that the cloned dogs will be as talented as their "fathers" because they are cloned. 人們希望這些克隆犬可以和它們的“父親”一樣有天賦，而且文章里提到了這些克隆犬的父親是破獲過大案的警犬�？芍�訓練他們是為了協(xié)助警方破案，故選B。

【2】細節(jié)理解題。根據文中It is hoped that the cloned dogs will be as talented as their “fathers” because they are cloned. The cloned dogs are just four months old, but have already shown that they’re brave and aggressive（有攻擊力的）,as well as have great memories, according to Ma Jinlei, a police officer at the center. It will take less time and money to train them. 人們希望克隆狗能像它們的“父親”一樣有天賦，因為它們是克隆的。據該中心警官馬金磊介紹，這些克隆狗雖然只有4個月大，但已經顯示出它們的勇敢和進取精神，也有著很棒的記憶力。訓練他們將花費更少的時間和金錢�？芍�這一段是講克隆狗的優(yōu)點，故選C。

【3】細節(jié)理解題。根據文中The world’s first cloned animal, Dolly the sheep, died at the age of 6 in 2003,about six years earlier than most sheep. Some people have questioned whether cloning technology is safe. 2003年，世界上第一只克隆動物綿羊多莉（Dolly The sheep）6歲時死亡，比大多數綿羊早6年左右。一些人質疑克隆技術是否安全�？芍�多莉羊的案例是為了說明克隆是否安全很難說，故選C。

【4】細節(jié)理解題。根據文中The world’s first cloned dog was born in South Korea in 2005. 2005年，世界上第一只克隆狗在韓國誕生�？芍�世界第一只狗在韓國誕生，故選A。

【5】推理判斷題。根據整個文章的描述可知，這里只要是講述六只克隆警犬的誕生以及世界上其他的克隆動物的介紹，說明克隆動物可以在某些方面幫助人類，故選A。
