D．what

Answer 1

D

試題分析：句意：群眾是不容易看到的新的發(fā)明對(duì)人類(lèi)有多大的用途。這里see后面接的是一個(gè)賓語(yǔ)從句，該從句缺少定語(yǔ)，變?yōu)殛愂稣Z(yǔ)序?yàn)椋篈 new invention can be of what use to human life. 本題易誤選為C項(xiàng)，which表示“在某個(gè)范圍內(nèi)的選擇”，意為：哪個(gè)，哪些。本句并未涉及范圍，故答案為D項(xiàng)。
點(diǎn)評(píng)：本題難度適中。
即學(xué)即練: I do every single bit of housework__________my husband Bob just does the dishes now and then.
A. since      B. while     C. when        D. as
解析：B。句意：考查并列轉(zhuǎn)折連詞while的用法。這里表示“我”和丈夫做家務(wù)的對(duì)比。根據(jù)句意，選B。
