◆動詞時態(tài)應注意的幾點
1.瞬間性動詞的一般現(xiàn)在時和現(xiàn)在進行時常用來表示將來的動作。例句：
①The film begins in a minute.
②My uncle is leaving tomorrow morning.
2.在時間、條件、讓步狀語從句中,常用一般現(xiàn)在時代替一般將來時。例句：
①Every time I listen to that song, I’ll think of my old friend.
②If you do that, I shall be very pleased.
③They’ll stand by you even if you don’t succeed.
3.一般過去時和現(xiàn)在完成時的區(qū)別：一般過去時和現(xiàn)在完成時都表示過去所發(fā)生的動作，但現(xiàn)在完成時強調這一動作與現(xiàn)在的關系，如對現(xiàn)在產(chǎn)生的影響、結果等，所以它不能和表示過去的時間狀語連用;一般過去時只表示過去的事實，不表示和現(xiàn)在的關系,因而它可以和表示過去的時間狀語連用。如：
—Have you finished your work?
—Yes, I have.
—When did you finish it?
—I finished it last summer.
◆直接引語與間接引語轉換時應注意的幾個問題：
1.人稱的變化
2.時態(tài)的變化
3.時間狀語的變化
4.地點狀語的變化
例句：
①Xiao Yi said, “I want to go to the park this afternoon.”
→Xiao Yi said (that) he wanted to go to the park that afternoon.
②Bob said, “We’ll have a meeting here tomorrow morning.”
→Bob said (that) they would have a meeting there the next morning.
◆定語從句中關系代詞只能用that和不能用that的幾種情況：
只能用that的情況
1. 先行詞是不定代詞。
例句：Please tell me everything that happened to you.
2.先行詞被形容詞最高級、序數(shù)詞或only, last, same, very等修飾。
例句： ①This is the most interesting movie that I have ever seen.
②This is the only book that I read during the summer holiday.
3.先行詞既包括人又包括物。例句：She talked about the writer and his works that interested her.
不能用that的情況
1.非限制性定語從句中。
例句：He said he could speak three foreign languages, which is not true.
2. 先行詞本身是that。
例句：I have that which you gave me.
3. “介詞+關系代詞”結構。
例句：The person to whom I talked just now is Tom.
◆現(xiàn)在完成進行時與現(xiàn)在完成時進行的比較：
1.強調動作還未結束時,多用現(xiàn)在完成進行時;強調動作的結果時,多用現(xiàn)在完成時。例句：
①I have been painting the paining. (強調“一直在畫”這個動作)
②I have painted the painting. (強調“畫完了”這個結果)
2.有些動詞不能用在現(xiàn)在完成進行時中，但可用在現(xiàn)在完成時中。如：have, love, see等。例句：
①She has had a cold for a week.
②They have loved each other for three years.
③I have seen this movie.
-ing形式：
1. having done
having done是非謂語動詞中-ing形式的完成式,而doing則是其一般式,它們都與句中主語構成邏輯上的主謂關系,只是doing與句中謂語動詞同時發(fā)生或基本上同時發(fā)生;having done則表示動作或狀態(tài)發(fā)生在句中謂語動詞之前。
[例句]
①Hearing the news, they got excited. (hear和get excited這兩個動作幾乎同時發(fā)生)
②Having arrived at the top of mountain, they took a rest. (arrive發(fā)生在take a rest之前)
