    when i was boy,the most exciting thing was when to celebrate the Spring Festival.
    WAS后為什么要加A?為什么不去掉TO,而是WHEN?
    and every year more and more people start a stamp collection of their own and discover an interest which can even last lifetime.last前加A,有什么用?
    介詞后什么情況下加冠詞?
    as we were all left home at early age.early前加AN可不可以理解為介詞后加不定冠詞呢?這句話還有毛病吧?

    優(yōu)質(zhì)解答
    規(guī)則是名詞作表語時一般要用冠詞
    因此是I was a boy.(系表結(jié)構(gòu))
    下一個,它的先行詞是 thing ,因此要用關(guān)系代詞(即that,which)而不能用關(guān)系副詞when,因此把when去掉或改為that.
    是last a lifetime吧?last是動詞,為什么會在前面加a?
    last同樣是系動詞
    prep+n介詞短語構(gòu)成狀語,名詞后加不加冠詞不是語法的,固定用法是怎樣就是怎樣了
    at an early age是固定用法
    on a bus=by bus,兩種都是固定用法,而前一種用冠詞,后者不用
