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”。

homework now.
(3)对过去的事进行推测, 用“must
have done”。

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。

becoming endangered.

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
