Question

When we do exercises, we must be ______.

A. as we can as careful

B.as we can as carefully

C.as careful as we can

D.as carefully as we can

 

Answer 1

答案：C
解析：

該題題意為“當(dāng)我們做練習(xí)時，我們必須盡可能地仔細(xì)一些”。由此可知應(yīng)用as…as we can結(jié)構(gòu)，排除A、B兩項(xiàng)；又因?yàn)榍懊嬗?/span>be動詞，所以應(yīng)用careful。故答案為C。
