Question

Although you have learned much knowledge and a lot of theories, the problem is _______ can be put into practice.

A．what you have learned	B．how what you have learned
C．that what you have learned	D．how that you have learned

Answer 1

B

試題分析：考查表語從句。本題中how引導(dǎo)起該表語從句，what you have learned在表語從句中做主語，what在該主語從句中做動(dòng)詞learn的賓語。句意：盡管你已經(jīng)學(xué)會(huì)了很多知識(shí)和理論，問題是你如何把你所學(xué)的知識(shí)付諸實(shí)施。故B正確。
點(diǎn)評：在該表語從句中how是引導(dǎo)詞，what引導(dǎo)起表語從句中的主語從句。在名詞性從句中要注意死于陳述語序，同時(shí)也要注意引導(dǎo)詞的選擇。
