    現(xiàn)在進(jìn)行時(shí)（1）
    （1）在英文中若想表達(dá)此刻正在進(jìn)行的動(dòng)作或事件，要用動(dòng)詞的現(xiàn)在進(jìn)行時(shí)形式。現(xiàn)在進(jìn)行時(shí)由be的現(xiàn)在時(shí)形式（am, is, are）+現(xiàn)在分詞組成。如課文中的Shes sitting under the tree 和Hes climbing the tree等句子均為現(xiàn)在進(jìn)行時(shí)。對(duì)大多數(shù)動(dòng)詞來說，在動(dòng)詞后面直接加-ing即可構(gòu)成現(xiàn)在分詞，如doing, climbing。以-e結(jié)尾的動(dòng)詞，要去掉-e，再加-ing，如making。如果動(dòng)詞只有一個(gè)元音字母而其后跟了一個(gè)輔音字母時(shí)，則需將與輔音字母雙寫，再加-ing，如running, sitting。
    （2）疑問式：將用了現(xiàn)在進(jìn)行時(shí)的句子變成一般疑問句時(shí)只需將助動(dòng)詞提前。如：
    Hes reading a magazine.
    Is he reading a magazine?
    他正在看一本雜志嗎？
    （3）否定式：現(xiàn)在進(jìn)行時(shí)的否定式是將否定詞not放在助動(dòng)詞之后。如：
    The dog is drinking its milk.
    The dog is not drinking its milk.
    狗沒在喝它的那份牛奶。
