Question

【題目】 Most people may not think that them am any problems with watermelons, but some Japanese sellers do. Them 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 squaw 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 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 the study finds no problems with the tomatoes, then patients can begin to use this easy and delicious new treatment.

文章大意：本文是一篇科普知識類閱讀，介紹了人們利用科學(xué)取得的幾項(xiàng)成果。日本的瓜農(nóng)把西瓜變成了方形的；澳大利亞的科學(xué)家培育出了藍(lán)玫瑰；中國的科學(xué)家研制出了新的超級水稻；美國的科學(xué)家利用西紅柿抗癌。

【1】細(xì)節(jié)理解題，根據(jù)Australian scientists have just recently discovered that when they put a chemical from a blue flower into a rose, they can create nearly 100% blue rose. 澳大利亞科學(xué)家最近發(fā)現(xiàn)，當(dāng)他們把一朵藍(lán)色的花中的一種化學(xué)物質(zhì)放入玫瑰中，他們可以創(chuàng)造出幾乎100%的藍(lán)色玫瑰。由此可知澳大利亞科學(xué)家找到了制作藍(lán)色玫瑰的方法，故答案選B。

【2】細(xì)節(jié)理解題。根據(jù)Super rice not only can protect itself against insects and diseases,可知，超級稻可以保護(hù)自己免受病蟲害，故答案選A。

【3】主旨大意題。根據(jù)原文主要介紹了隨著科技的發(fā)展，西瓜因?yàn)樾枰�可以做成方形，大米也可以開發(fā)出可以防蟲和疾病的超級大米，醫(yī)生用蔬菜（西紅柿）來對抗癌癥等等。可知文章在講科技是如何改變植物進(jìn)而改變了人們的生活，故答案選C。
