英語時態(tài)的語法總結(jié)
【基本用法】
“過發(fā)現(xiàn)影”--- 表示過去發(fā)生，對現(xiàn)在造成了影響。
e.g. Their parents have known the good news.They look excited.
“過發(fā)持續(xù)”--- 表示從過去開始，持續(xù)到現(xiàn)在的`動作或狀態(tài)。
e.g. I have learned English for 10 years.
“經(jīng)歷” --- 表示曾經(jīng)做過某事，或曾做過n次
e.g. I have seen the film Titannic twice.
【時間狀語】
already, just, yet, since, since then, for, recently / lately,
so far = till / until now = up to now, in the last / past few years,
How long…ever, never, before, once, …times
【重難點(diǎn)】
延續(xù)性與非延續(xù)性動詞的用法
什么時候才必須用延續(xù)性動詞？ 出現(xiàn)how long, for+時間段, since+時間點(diǎn)
非延續(xù)性動詞轉(zhuǎn)化
▲ 高頻考點(diǎn)
borrow → keep buy → have
finish / end → be over begin / start → be on
open → be open die → be dead
join → be in / be a…member leave →be away（from）
▲ 需了解記憶
get up → be up fall asleep → be asleep
fall ill → be ill, lose → be lost
become → be return / come back / get back → be back
close → be closed catch / get a cold → have a cold
arrive /come / go / move / reach /get to → be in /at / be here /be there
【易錯點(diǎn)】
in the past few years (不是 a few)
have been to, have gone to和have been in的區(qū)別
already與yet區(qū)別
since+時間點(diǎn)，for+時間段（since 3 years ago; for 3 years）
since 引導(dǎo)的從句要用一般過去時
It is /has been + 時間段 + since + 從句（一般過去時）
He came to our school in 2000, since then he has taught English here.
