Question

    Many people don't consider their breakfast without a glass of milk． Right now， cows， buffalos， goats and sheep provide most of the world's milk． But soon， people could get milk from roaches（蟑螂）．

That isn't as crazy as it might sound． New research shows this "milk" is super﹣nutritious． What's more， some scientists have already begun referring to a lot of insects as source of milk．

In 2004， Subramanian Ramaswamy started studying milk crystals found inside the roach． At the time， he was teaching biochemistry at the University of Iowa City．

To learn more about the milk crystal from roaches， the scientists used X﹣rays to look at the atoms in it． The data basically revealed the chemical recipe of the roach crystal． They showed that roach milk is a "complete food"． It contains sugar with a fatty acid stuck to it． Fatty acids are the building blocks of fats． The protein in the milk is also full of essential amino（氨基的） acids， which are the building blocks of proteins． Since our bodies can't produce the "essential" ones， we need to get them from our food． And so do baby roaches．

Barbara Stay， a biologist at Iowa University， also worked on the new study． She says the new data show that the roach milk is "three times more nutritious than cow's milk and four times more nutritious than buffalo's milk"．

Ramaswamy would like to see roach milk turned into a protein supplement to feed hungry people． But not everyone is confident that it can be done．

Marcel Dicke studies insects as a potential source of human food at Wageningen University in the Netherlands． Dicke says this is a "sound study"． However， in his opinion， "Extracting（提取） milk from roaches can only likely be done in a destructive way with only small quantities"． That means you'd have to raise and kill many bugs to get even tiny quantities of the milk．

1.What is the opinion of the scientists about milk in Paragraph 2？

A. Many insects are sources of milk．

B. Milk is an important part of breakfast．

C. Milk from insects is the most nutritious．

D. Milk from insects is well accepted now．

2.What can we know about the use of roach milk in life？

A. It will replace the milk from animals like cows．

B. Scientists think it the key to solving world hunger．

C. All people don't think it can be used in life soon．

D. Most people depend on roach milk from protein．

3.According to Marcel Dicke， extracting insect milk on a large scale is　   　．

A. simple

B. challenging

C. safe

D. necessary

4.What should be the best title for the text？

A. Roach milk has been found scientifically

【解析】

本文为科普说明文。一些科学家已将许多昆虫作为牛奶的来源并对此正进行研究，新的研究表明可从蟑螂中获取牛奶，还说这种牛奶的价值很高。不是所有的人认为它能很快运用于生活中，但有些科学家对此很有信心。

1.细节理解题。根据第二段中的最后一句“What’s more, some scientists have already begun referring to a lot of insects as source of milk.” 一些科学家已经开始将许多昆虫称为牛奶的来源。由此可知A项符合题意。

2.细节理解题。根据文章的第六段Ramaswamy希望看到Roach milk变成蛋白质补充剂来养活饥饿的人。但并不是每个人对这一点都有信心。分析选项C项（并非所有人都认为它能很快用于生活）与之符合，故选C项。

3.推理判断题。根据最后一段中的后半部分Dicke says this is a “sound study”. However, in his opinion, “Extracting(提取) milk from roaches can only likely be done in a destructive way with only small quantities”. That means you’d have to raise and kill many bugs to get even tiny quantities of the milk.迪克说这是一个“合理的研究”。然而，在他看来，“从Roach 中提取牛奶只可能以一种破坏性方式得到很少量的牛奶。”这意味着你必须饲养和杀死许多虫子才能获得少量的牛奶，不容易。分析选项A. simple简单的；B. challenging有挑战性的；C. safe安全的；D. necessary必要的。可知B项符合题意。

4.主旨大意题。通读全文可知， Roach milk很快就会出现，而且一些科学家已将许多昆虫作为牛奶的来源并对此正进行研究。新的研究还说这种牛奶的营养价值很高，有些科学家对此很有信心。由此可推断出这种Roach milk将会被广泛运用。故选C项。
