【问】 He knows little of mathematics，_________of chemistry.

A. as well as B. still less

C.on less than D. still more(日本高考试题，81)

请就上面的试题谈谈still less的用法。

【答】 still less属并列连词之列，亦作much less，even less，它的同义词语是let alone。但后者为非正式用法。still less( much less)，同let alone一样，大都用于否定句之后。例如：

1. I don't suspect him of robbery，still less of robbery with violence. (OSD)

我没有怀疑他抢劫，更不用说暴力抢劫了。

2. I've not even read the first chapter，still less finished the book. (CGEL)

我连第一章都没有读完，更不用说读完全书了。

3. The baby can't even walk，much less run.(LDCE)

这个婴儿连走都不会，更不用说跑了。

4. He can't run a hundred yards，even less a mile.

他连100码都跑不了，更不用说1英里了。

请做下面的英语试题：

1. I've never been back since we moved out，not even to the town，________ to the housewhere I was born.

A. even not B. still not C. still less D. even ever

2. The amount of knowledge in all the sciences has grown at such a rapid rate that no onecan keep fully abreast of one major field，_______ mor e than one.
