agriculture.
[考点] therefore adv. 因此；所以；
因而，表示因果关系。[考例] Progress so far has been very good. ______, we are sure that the project will be completed on time.
A. However B. Otherwise
C. Therefore D. Besides [点拨] 题意是“至今情况进展良好，因此我们确信能按时完成这项工程。” 前后两句为因果关系，故选therefore；however然而，可是；otherwise否则，要不然，二者均表示转折关系；besides而且，也不符合题意。Important sentences 1. What do you think would happen if tomorrow there was suddenly no rice to eat?
[点拨] 本句中使用了插入语do you think。插入语经常插到一个语法结构完整的句子里去，对句子的内容作一些附加说明，有时表示说话者的态度和看法等，它不和句子的成分发生结构上的关联，常置于句首、句中或句末。把插入语去掉之后，句子的结构和语义还是完整的。 [拓展]

C. If anything D. If possibleDB2. Although he is one of China’s most famous scientists, Yuan Longping considers himself a farmer, for he works the land to do his research.
[分析]
①这是一个含让步状语从句的主从复合句。其结构为: 让步状语从句(Although he is one of China’s most famous scientists)+主句(Yuan Longping considers himself a farmer)。
②主句中包含“consider + 宾语 + n.”结构。③ for引导的从句并不表示原因, 而只是为主句中所说的话提供推断的理由, 加以解释, 此时for前要加逗号。
e.g. The shop was quite new, for it had
opened only the week before.
work vi./ vt. 经营, 管理
work the land = grow crops on it 耕耘土地　
e.g. He works a big farm. 他经营着一个大的农场。3. In 1974, he became the first agricultural pioneer in the world to grow rice that has a high output.
the first ... to do sth. 意为“第一个做……”。本句中动词不定式(to grow rice) 作定语, 修饰the first agricultural pioneer。the first, the last, the second, the only等短语后面多用动词不定式作后置定语。[仿写] __________________________ __________________________ ___________________________

it做形式宾语, 通常和下列动词连用:
consider, think, make, find, believe, count, declare, deem, fancy, feel, guess, imagine, judge, prove, see, show, suppose, understand, take等。We consider it our duty to support good leaders.
