III.【合作探究，问学质疑】

1.The plant allowed farmers to rest in its shade.译:_____________________________. allow 的用法

1)allow作“允许”或“许可”讲，常搭用动词不定式短语作宾语补足语

即，allow sb. to do sth.允许某人做某事

例：①Please allow me to carry your bag. 请让我替你拿包。

②My boss doesn't allow me to use the telephone. 我的老板不允许我用电话。

2)allow 作“许可”，“允许”讲，只可搭配动名词短语作宾语，不可直接搭用动词不定

式作宾语，即只可说 allow doing sth., 不可说allow to do sth.

例：①They allowed smoking in this room only. 他们只允许在这间屋子里抽烟。

②Smoking is not allowed here. 此处禁止吸烟。 第

People all over the world eat rice. Millions of people in Asia, Africa, and South America live on it. Some people eat almost nothing but rice. Rice is a kind of grass. There are more than 7,000 kinds of rice. Most kinds are water plants. Farmers grow rice in many countries, even in the south of the United States and in eastern Australia. China is the world’s largest rice-growing country. In 2003, China grew 166 million tons of rice. But it is not easy to feed the world’s largest population. In the 1960s, thousands of Chinese died because they didn’t have enough food to eat. In the 1970s, Yuan Longping, a Chinese scientist, grew a kind of rice called hybrid（杂交） rice. It makes 20% more rice than any other kind. Hybrid rice is a stronger plant, unlike ordinary rice. It can grow in lots of water or in not much water. It doesn’t easily get diseases or worms.

Today, half of China’s rice plants are Yuan’s special hybrid rice. China uses Yuan’s hybrid rice to grow much more rice than before. Yuan is known as the Father of Hybrid Rice. He won the World Food Prize for his work to help feed so many people. Choose the best choice from ABC or D according to the passage above. 第

水稻，以及他在自己平凡的工作岗位上为国家做出的杰出贡献，向学生渗透热爱科学的理念，培养学生脚踏实地，认真做事、做学问的求实精神。

第一道小题的设题属于语义理解性题目，在世界的什么地方可以种植水稻，从文章中的第一段中“Farmers grow rice in many countries”，只有答案A中用的“lots of”这个词，many与lots of是同义词，因此从这句话可以选出答案A是正确的。

第二道小题也属于语义理解性题目，从第二段的第一句话“China is the world’s largest rice-growing country.”可以推断出答案B是正确的。

第三道小题属于直接理解性题目，从第二段中的“It makes 20% more rice than any other kind.”可以选出答案D是正确的。

第四道小题属于归纳概括性题目，需认真阅读全文，仔细推敲每个答案：答案A具有片面性，文章中说他是the Father of Hybrid Rice而不是the Father of Rice；答案B 的题干是his rice to feed all Chinese，而在文章中说half of China’s rice plants are Yuan’s special hybrid rice，此答案明显是不正确的；答案C是正确的；答案D的题干是growing different kinds of rice，而从文章中可以得知Yuan Longping只是种植杂交水稻。答题时考生要在正确理解短文内容的基础上，认真看清短文后的题目内容和要求，然后根据短文内容，运用分析、排除等方法选择正确答案。对短文中没有直接说明又无法从短文所提供的材料上明确做出判断的，就要在理解字面意第
