英語四級語法備戰(zhàn)-as的用法大全

二、 as作關(guān)系代詞,引導(dǎo)定語從句,作"正如"、"這一點(diǎn)"解。如:

He is very careful, as his work shows.

As is well-known, Taiwan belongs to China.

as的這種用法,請看2001年的高考題:

is known to everybody, the moon travels round the earth once every month.

A. It B. As C. That D. What

(字母下劃橫線的為正確答案)

另外,當(dāng)先行詞被the same, such等詞修飾時(shí),常用as來引導(dǎo)定語從句。如:

Such a clever boy as he can learn anything quickly.

I was reading the same book as he bought yesterday.
