Question

【題目】閱讀下面材料，然后從各題所給的四個(gè)選項(xiàng)中選出一個(gè)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.

Answer 1

【答案】
（1）C
（2）C
（3）A
（4）C
【解析】這是一篇說(shuō)明文。主要講了科學(xué)家通過(guò)科學(xué)改變了人們的生活：方形西瓜。藍(lán)玫瑰，超級(jí)大米等等。
（1）細(xì)節(jié)理解題。根據(jù)第一段“They make their watermelons grow in square glass boxes so the watermelons become square. ”可知，他們讓西瓜生長(zhǎng)在方形的玻璃盒子里，所以西瓜就變成了方形。故選C。
（2）細(xì)節(jié)理解題。根據(jù)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，澳大利亞科學(xué)家最近發(fā)現(xiàn)當(dāng)他們把一種來(lái)自藍(lán)色花朵的化學(xué)物質(zhì)放在玫瑰里，他們可以創(chuàng)造出接近100%的藍(lán)玫瑰。故選C。
（3）理解判斷題。根據(jù)倒數(shù)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，超級(jí)大米不僅可以保護(hù)自己免受蟲(chóng)害和疾病，而且它比其他任何一種大米都生產(chǎn)的多。故選A。
（4）主旨大意題。通讀全文可知，本文主要講了幾例科學(xué)家的創(chuàng)造，例如方形西瓜和超級(jí)大米等。故選C。
