即时体验　巩固提升
Ⅰ.单句语法填空(不多于3个单词)
1．Charles Babbage is generally considered ________ (invent) the first computer.
答案与解析　to have invented　consider sb. to do sth.“认为某人做某事”，且题干中the first computer示意invent的动作发生在consider之前，因此用不定式的完成式，表示不定式动作发生在谓语动作之前。
2．Either you or one of your students ________ (be) to attend the meeting that is due tomorrow.
答案与解析　is　依据时间状语tomorrow可知应当用be to do结构表将来时态。either ... or“或者……，或者”，连接两个主语时，句子的谓语与最近的一个主语保持全都。最近的主语是one of your students，谓语动词用单数。
3．Our bodies are strengthened by taking exercise. ________(similar), our minds are developed by learning.
答案与解析　Similarly　句意：身体是靠熬炼变强壮的，同样，我们的大脑通过学习得以开发。similarly在这里意思是“同样；也”。
4．I can not go shopping with you because I have ________ couple of things to do.
答案与解析　a　句意：我不能和你一起去购物，由于我有一些事情要做。a couple of“几个；三两个”，为固定搭配。
5．She was lying in the sun, looking very ________ (relax) and happy.
答案与解析　relaxed　look作“看起来”讲时为系动词，后接形容词作表语，relaxed“松懈的；放松的”，常用于修饰人。
