friends.vWhen heated, the ice will change into water.v要注意不定式和分詞作賓語補足語的不同:v在感官動詞(see, watch, hear, feel, notice等)后既可用不帶to 的不定式做賓語補語,也可用現(xiàn)在分詞做賓補。兩者中間有時是有差別的。用現(xiàn)在分詞時,表示動作正在發(fā)生,用不定式時,表示動作發(fā)生了,即動作全部結(jié)束了。例如:v A: Do you hear someone knocking at the door?v B: Yes, I did. I heard him knock three times.v不定式和分詞作定語時的區(qū)別,不定式作定語時,不定式和所修飾的名詞在意義上有動賓關(guān)系,因此,如果不定式是不及物動詞,后面就應有必要的介詞。如果是分詞作定語, 則被修飾的名詞和分詞之間有主謂關(guān)系。例如:vGive me a piece of paper to write on.vAll of us look forward to the ing holiday.非謂語動詞v. 動名詞和不定式做主語和表語時的區(qū)別。一般來說,在表示比較抽象的一般的行為時,多用動名詞, 表示具體某次動作,特別是將來的動作時,多用不定式。例如:vReading without thorough prehension is no good.vIt is quite necessary to read it many times.1。We let the raft sail down the river.2.
