3. You must be aware that it’s here that we’ve found evidence of some of the earliest people who lived in this part of the world. 想必你们知道, 正是在这儿我们找到了居住在世界这一地区最早人类的证据。

a. You must be aware that…主句后接由强调句和定语从句组成的宾语从句。

(1)must是作为情态动词表示肯定推测, 译作“一定,肯定”。只用于肯定推测。 对现在或将来事实推测,用 “must do”。

You must be hungry after a long walk.

(2)对正发生或进行的事进行推测, 用“must be doing”。

The light is on. He must be doing his homework now. 

(3)对过去的事进行推测, 用“must have done”。

The ground is wet. It must have rained last night.

此时, 应注意反意疑问句的构成。如果句中有表示过去的时间状语, 反意疑问句用“didn’t+主语”; 如果句中无表示过去的时间状语, 反意疑问句用 “haven’t/hasn’t+主语”。

He must have arrived here last night, didn’t he?

He must have arrived here, hasn’t he?

b. aware adj. 意识到的, 知道的。通常用作表语。  

We should be aware that a lot of animals are becoming endangered.

be aware of sth. 知道;意识到

Though most smokers are aware of the dangers of smoking, they won’t given up.    

c. it’s here that we’ve… 是强调句,其基本句式是It is (was)+被强调部分+that (who)+句子其他部分。此结构强调的成分仅限于主语,宾语和状语。
