Planting TreesPPT,第三部分内容:Language  Points

1.It must be large enough to hold the roots of the seeding. 它必须足够大以容纳的种子根。

must是情态动词,意为“必须;肯定”。用在肯定句中表示较有把握的推测。对现在的状态或现在正发生的事情的推测时,must后面通常接系动词be 的原形或行为动词的进行式。如:

You have worked hard all day. You must be tired. 你辛苦干一整天,一定累了。

2. Now, put the seedling inside, cover the roots and fill the hole with dirt. 现在,把幼苗放进来,盖上根,用泥土填上坑。

fill作动词,常用动词词组fill… with…意为“用……把……装满”,被动形式: be filled with意为“装/填满”,相当于be full of,full是形容词,意为“装满;充满”。如:

He filled his backpack with books. 他把书装进书包。

3. I suppose tree planting is very important work. 我想,植树造林是非常重要的工作 。

suppose是及物动词,常用来表示说话人的看法、猜测或假设。其基本用法如下:

(1)“suppose+名词/代词+介词短语”表示“猜测某人/某物在……”。如:

He supposed his friend in the library. 他猜想他的朋友在图书馆里。

(2) be supposed to中的to是动词不定式符号,后接动词原形,主语为人时,表示“应该;被期望”,它可以用来表示劝告、建议、义务、责任等。主语为物时,它表示“本应;本该”,用于表示某事本应该发生而没有发生。它还可以用来表示“被认为是;被相信是”。如:

I am supposed to start work at 7:30 every morning. 我理应每天早晨7:30开始工作。
