Question

【题目】阅读下面材料，然后从各题所给的四个选项中选出一个最佳答案。
B
Most people may not think that there are any problems with watermelons, but some Japanese sellers do. There is often wasted space when they store watermelons, because round watermelons do not sit nicely on shelves. So some clever farmers have solved the watermelon problem. They make their watermelons grow in square glass boxes so the watermelons become square. The only problem now is the price. The square watermelons cost about 80 dollars each.
Many people know the saying "Roses are red, violets are blue, sugar is sweet and so are you." Well, today the poem needs to change to "Roses are red, roses are blue"! Australian scientists have just recently discovered that when they put a chemical from a blue flower into a rose, they can create a nearly 100% blue rose. Some of science's inventions are beautiful, not just useful!
Since the mid-1990s, many Chinese farmers have had amazing rice harvests. For many years Chinese scientists have been working on developing new kinds of stronger rice and now they have produced a new kind, called super rice. Super rice not only can protect itself against insects and diseases, but it also produces more than any other kind of rice, today farmers can grow almost one and a half times more rice than they could grow in the past.
Doctors might be able to use vegetables to fight cancer now. US scientists have discovered a way to put a chemical into tomato plants while they are growing. When cancer patients eat the tomatoes, the tomatoes will fight the cancer in their bodies. These cancer-fighting vegetables are not yet for sale, because scientists have not finished testing them. If study finds no problems with the tomatoes, then patients can begin to use this easy and delicious new treatment.

【解析】这是一篇说明文。主要讲了科学家通过科学改变了人们的生活：方形西瓜。蓝玫瑰，超级大米等等。
（1）细节理解题。根据第一段“They make their watermelons grow in square glass boxes so the watermelons become square. ”可知，他们让西瓜生长在方形的玻璃盒子里，所以西瓜就变成了方形。故选C。
（2）细节理解题。根据第二段“Australian scientists have just recently discovered that when they put a chemical from a blue flower into a rose , they can create a nearly 100% blue rose. ”可知，澳大利亚科学家最近发现当他们把一种来自蓝色花朵的化学物质放在玫瑰里，他们可以创造出接近100%的蓝玫瑰。故选C。
（3）理解判断题。根据倒数第二段“Super rice not only can protect itself against insects and diseases, but it also produces more than any other kind of rice,”可知，超级大米不仅可以保护自己免受虫害和疾病，而且它比其他任何一种大米都生产的多。故选A。
（4）主旨大意题。通读全文可知，本文主要讲了几例科学家的创造，例如方形西瓜和超级大米等。故选C。
