Unit3
Inventors and inventions
1.Do you know the stages every inventor must go through before they can have their invention approved?你了解每个发明家在他们的发明得到认可之前必须经历的阶段吗？
have+宾语+宾语补足语
have sth. done
The patient is going to have his temperature taken.
让/叫别人为自己做某事
自己遭遇某事
使某事完成（主语参与）
(2)have sb. do sth. 让某人做某事
此时宾语与宾补之间是主谓关系，相当于 let/make sb. do sth.或get sb. to do sth.
The director had her assistant pick up some hot dogs for the meeting.
(3)have sb. doing sth.
肯定句：让某人一直做某事；否定句：不允许/容忍某人做某事
There be 句型的常见结构
There be+某物/某人+某地/某时
There +情态动词+be+其他
There used to be +其他
There stands/lives/exists/remains/lies/comes…+其他
There being…+其他
There seems/happens/appears to be+其他
3.But once picked up, they tried to bite me.
但是一把它们提起来，它们就试图咬我。
此句为省略句，状语从句的省略。
当状语从句的主语和主句的主语一致或从句主语是it，且从句中含be动词时，可以省略状语从句中的主语和be动词，这时从句中可以出现的结构：
(1)连词+名词/形容词/介词短语
Work hard when young, or you’ll regret.
(2)连词+现在分词
While talking on the phone, keep conversation volume to a normal level.
(3)连词+过去分词
If accepted for the job, you’ll be informed soon.
(4)连词+不定式
The patient woke up and opened his mouth as if to say something.
(1)否定词(短语)位于句首时引起部分倒装
表示否定意义的词有：neither, not, never, seldom, hardly, rarely(很少), little, by no means(决不), nowhere(没有地方), at no time(决不), not until等位于句首时，句子要用部分倒装，即把助动词/be动词/情态动词移至主语之前。
(2)so位于句首时，表示甲的情况也适用于乙，句子用部分倒装。
(3)so/such…that…结构中,so/such位于句首，主句部分倒装。
(4)no sooner…than…,hardly/scarcely….when…中，no sooner，hardly/scarcely位于句首，主句部分倒装。
(5)not only…but also…连接并列分句，且not only位于句首，not only后的分句部分倒装
(6)as引导的让步状语从句必须采用部分倒装, though引导的让步状语从句可倒可不倒。结构为：表语/状语/动词原形+as/though+主语+be动词/情态动词/助动词
9.Each idea tested by you will need to be improved until it leads you closer to a new invention.
本句为复合句，until it leads you closer to a new invention为时间状语从句。句中need为实义动词，意为‘需要’。句中need to be improved可以用 need improving替换，此时，v-ing主动表被动含义。
need doing / to be done
归纳：
need/require/want(需要)/deserve(应受,应得)后接不定式的被动形式时，可用动名词的主动形式替换：want loving=want to be loved。
needn’t have done 本没必要做而实际上做了
need做情态动词时，没有人称和数的变化，后面+动词原形；做实义动词时，有人称和数的变化。
10. You’d better have your bedroom tidied before I get home from work.你最好在我下班回家之前整理好你的卧室。
before引导的时间状语从句
before做连词表示时间，在句中根据实际情况有不同的含义。
(1)在…之前
Mary had finished her homework before her mother returned.
(2)….(之后)才….
He was told that it would be at least three more months before he could recover and return to work.
(3)还没来得及…就…
---Why didn’t you tell him about the meeting?
---He rushed out of the room before I could say a word.

I’m sorry you’ve been waiting so long, but it’ll still be some time before Brian gets back.
