Question

【題目】The police find most criminals (罪犯) because somebody tells them who the criminals are. They find other criminals by using science and their computers. When there is a bank robbery (搶劫), the police first look through their computers for the names of the bank robbers that they know about. Then they go and talk to any of these robbers who are not in prison (監(jiān)獄). They ask them where they were when the robbery happened. If any of these people cannot give a good answer, the police will often use science to find out if one of them is the robber.

Many criminals leave something of themselves at the places of the crimes like a fingerprint or a hair. Or they take something away on their shoes or clothes, like dirt or animal hair. If they leave behind some of their blood or their hair or a piece of skin, it will have their DNA inside it.

Everyone’s DNA is different and their fingerprints are also different. So, if a criminal cuts himself during a robbery or leaves his hair, or even a small piece of skin, scientists can find out what his DNA is. The police can then ask the person they think is the robber to give them his hair or some blood and see if it has the same DNA. Many criminals are in prison today because of this kind of evidences .

【解析】試題分析：短文大意：這篇短文主要介紹了現(xiàn)代社會警察破案的一些方法，他們可以通過訊問在押的囚犯，以及罪犯留下的指紋，頭發(fā)及DNA等信息來確定罪犯的身份。

【1】【1】細節(jié)理解題。本句是說因為使用電腦，警方通常能找到罪犯。根據(jù)The police find most criminals (罪犯) because somebody tells them who the criminals are.可知本句描述錯誤。

【2】【2】細節(jié)理解題。本句意思是，關(guān)于犯罪問題，警方通常不訊問在監(jiān)獄里面的罪犯，因為他們不可能做這些事。根據(jù)When there is a bank robbery (搶劫), the police first look through their computers for the names of the bank robbers that they know about.描述，可知只有當發(fā)生了搶劫后，警方才會訊問監(jiān)獄里面的囚犯，故本句描述正確。

【3】【3】細節(jié)理解題。本句是說罪犯留在罪行發(fā)生的地方的最重要的證據(jù)是他們的DNA，根據(jù)短文后兩段描述，可知本句描述正確。

【4】【4】細節(jié)理解題。本句是說在罪行發(fā)生后，罪犯通常只把鞋上面的一些東西帶走。根據(jù)短文倒數(shù)第二段描述，可知可以作為證據(jù)的不只是罪犯鞋上面的東西，因此罪犯要帶走的不止這些東西，故本句描述錯誤。

【5】【5】主旨大意題。本句是說這個故事是有關(guān)銀行搶劫的。閱讀短文可知，這是一篇關(guān)于警察如何破案的短文，故本句描述錯誤。
