  3.Yuan Longping searched for a way to increase rice harvests without expanding the area of the fields.

  袁隆平要在不增加土地面积的基础上寻求增收稻谷的途径。

  剖析:句子中的动词不定式短语to increase rice harvests在句子中作定语,修饰a way。如:

  Can you think of a way to solve the problem?

  你能想出一个办法来解决这个问题吗?

  考点 expand vt.& vi.使变大;伸展

  She expanded her store by adding a second room.

  她通过再增加一间房子来扩大自己的商店。

  The flowers expanded in the sunshine.

  花儿在阳光下开放了。

  Our foreign trade has expanded greatly in recent years.

  我国的对外贸易近几年来已有很大发展。

  考点延伸 1)expand还有"细说;阐述"的含义。如:

  You mentioned the need for extra funding.Would you please expand on that?

  你提到了增加资金的必要性,请你充分叙述一下好吗?

  归纳:expand作"细说;阐述"讲时,常与介词on连用。

  2)expand的名词为expansion。expansion作"扩大;膨胀"等讲时,是不可数名词;作"扩大物;增加部分"讲时,则是可数名词。

  3)辨析expand与extend:

  expand是"范围"扩张;extend意为"延伸",也有"扩张"的意思。
