1)
逗號的使用方法比較復(fù)雜,一兩句不是能說清楚,最好比對 句號和分號的用法來看.
簡單來說,一,逗號后面可以是一句話,he came here and had a look----he came here ,and he had a look.逗號成分要齊全.當(dāng)然與此類似的還有but or yet 等等
,
二后面接非限定定語從句 I learnt English well in the past,which helped me a lot when I worked
三逗號后接分詞從句.The two boys were on their way to school,singing a funny song.
四表并列,相當(dāng)于我們的頓號
五插入語,He ,a student from high shool,finally won the contest.
4 及物動詞不加賓語 為省略,多用于口語
