答案详解
1.[B]【解析】固定用法。still less一般用于否定句中,继前面的否定对相关的另一件事予以更强有力的否定,意为“更不用说,何况”。而as well as常用于连接两项类似的事情,意为“既……又……”;no less than意为“不少于”;still more意为“何况,更不用说”,一般用于肯定句中。因此,B项为正确答案。句意:宝宝连走路都不会,更别说跑了。
2.[A]【解析】非谓语动词。状语从句的省略必须同时省略与主句相同的主语及动词be, 因为省略前的句子是:Even if (I am) invited,因此A项是正确答案。句意:即使接到邀请,我也不会去。
3.[B]【解析】介词的用法。句中agree with表示“适合于”,多用于“气候”、“食物”等,其他选项都不符合题意。agree on意为“在……方面一致”,agree to为“同意……”,无agree for此词组。因此B项是正确答案。句意:你能适应山上稀薄的空气吗?
4.[D]【解析】定语从句。by means of意为“通过(某种方式)”,符合题意。而for which也可用于引导定语从句,表示目的;of which一般用于修饰定语从句;as a result of which相当于because of/ due to which,表示由其引导的定语从句与其所修饰的主句构成因果关系,因此D项是正确答案。句意:超声波能产生脉冲信号,通过这些信号就能检测出金属中的各种缺陷。
5.[C]【解析】倒装句。由although引导的让步状语从句,可以换成由as引导的倒装句形式,句型一般为adj.(adv.或v.)+as+主语+谓语。而其他三个选项A,B,D都不能表达让步意义。因此C项是正确答案。句意:虽然钻石坚硬,但用激光很容易就能在上面钻孔。
