II have (v.s.)get

有時用 get 代替 have ，在意義上不同。

get＋受詞＋過去分詞/不定詞

I ____________(have/get) a tooth out this afternoon.

get比have 語氣強，含有強調主詞所做的動作之意。

”好不容易才做成”

   I finally ___________(get) my roof ______________(repair).

III在祁使句，get比have更自然：

______________(get/have)　your hair cut.

_______________(get/have) your eyes tested.

Why don’t you….?表示建議的句子中，用get比have　語氣要強得多。

Why don’t you __________ your hair cut?（一般建議）

Why don’t you __________ your hair cut?（近乎命令）

IV get ＋受詞＋to＋不定詞 表 示「說服、設法」的意思：

1I finally _________ the car __________________(start) by asking everyone to push it.

2I _________ the job ___________(do).
