語法是英語學習過程中最難掌握的知識，要想提高自己的英語學習效率，積累和掌握很重要。下面是關(guān)于英語時態(tài)知識，大家可以作為學習的參考。

【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】 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

非延續(xù)性動詞轉(zhuǎn)化

▲ 高頻考點

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】 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，for+時間段(since 3 years ago; for 3 years)

since 引導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.

學好英語并非三兩天的事，在學習的過程中掌握方法可以有效提高學習效率。
