[句型归纳]

[考点l]It is on this arable land that the farmers produce

food for the whole population of China. 就在这些耕地

上，农民们生产了供给全中国人口的粮食。

It was from the early 1990s that scientists started to de-

velop new techniques to increase agricultural production

without harming the environment. 90年代初，科学家开

始了新的技术，在不损害环境的基础上增加农业产量。

该两句中的it用于强调句型。

it可以用来改变句子的结构，使句子的某些成分受到强

调。强调的基本句型结构为：It is / was + 被强调部分

+ that + 句子的剩余成分。

强调句型可分别强调主语、宾语、地点状语、时间状语

等。例如：

rose. 就是在圣诞节。杰克送给简一朵漂亮的红玫瑰。
