语法 Grammar in use
现在进行时(1)
(1)在英文中若想表达此刻正在进行的动作或事件,要用动词的现在进行时形式。现在进行时由be的现在时形式(am, is, are)+现在分词组成。如课文中的Shes sitting under the tree 和Hes climbing the tree等句子均为现在进行时。对大多数动词来说,在动词后面直接加-ing即可构成现在分词,如doing, climbing。以-e结尾的动词,要去掉-e,再加-ing,如making。假如动词只有一个元音字母而其后跟了一个辅音字母时,则需将与辅音字母双写,再加-ing,如running, sitting。
(2)疑问式:将用了现在进行时的句子变成一般疑问句时只需将助动词提前。如:
Hes reading a magazine.
Is he reading a magazine?
他正在看一本杂志吗?
(3)否定式:现在进行时的否定式是将否定词not放在助动词之后。如:
The dog is drinking its milk.
The dog is not drinking its milk.
狗没在喝它的那份牛奶。
