高中英語定語從句的介紹
(一)基本概念
1.由一個(gè)句子作定語，修飾句中一個(gè)名詞或代詞，有時(shí)也可以修飾整個(gè)句子或句中的部分內(nèi)容，這樣的從句就是定語從句，被其修飾的名詞或代詞叫先行詞。
2.關(guān)系詞分為兩大類，即關(guān)系代詞和關(guān)系副詞，其作用一是引出一個(gè)定語從句，二是代替其所修飾的先行詞，三是在句中充當(dāng)某個(gè)句子成分。

高中英語的時(shí)態(tài)用法的介紹
1. 將來完成時(shí)的基本用法
表示到將來某個(gè)時(shí)間為止勢必會(huì)完成或預(yù)計(jì)要完成的動(dòng)作，由will [shall]+have+過去分詞構(gòu)成：
He will have arrived by now. 他現(xiàn)在應(yīng)當(dāng)已經(jīng)到了。
He will have gone back to England.他想必回英國去了。
When we get there，shell have gone to work. 我們到那里時(shí)她會(huì)已上班去了。
On Monday hell have been in Britain for three years. 到星期一，他在英國就滿三年了。
2. 現(xiàn)在完成時(shí)、過去完成時(shí)與將來完成的區(qū)別
現(xiàn)在完成時(shí)以現(xiàn)在時(shí)間為參照點(diǎn)，表示在現(xiàn)在以前完成的動(dòng)作或持續(xù)到現(xiàn)在的狀態(tài)，過去完成時(shí)則以過去時(shí)間為參照點(diǎn)，表示在過去某一時(shí)間以前發(fā)生的動(dòng)作或持續(xù)到過去某一時(shí)間的狀態(tài)，將來完成時(shí)則以將來時(shí)間為參照點(diǎn)，表示在將來某一時(shí)間為止已經(jīng)完成的動(dòng)作或持續(xù)到將來某一時(shí)間的狀態(tài)：
He has finished writing his novel. 他已寫完了他的小說。
He had finished writing his novel by the end of last year. 去年年底他就寫完他的小說。
He will have finished writing his novel by the end of next year. 到明年年底他就會(huì)寫完他的小說了。
與一般現(xiàn)在時(shí)代替一般將來時(shí)一樣，在表示時(shí)間或者條件的狀語從句，通常要用現(xiàn)在完成時(shí)來表示將來完成時(shí)，而不能直接使用將來完成時(shí)：
I will go with you when I have finished my work. 等我完成工作之后我就同你去。
若不強(qiáng)調(diào)動(dòng)作的完成(且不致于引起歧義)，有時(shí)也可用一般現(xiàn)在時(shí)：
I will go with you when I finish my work. 我完成工作后就同你去。
