Question

_______ the Internet is of great help, I don't think it's a good idea to spend too much time on it.
A If                   B While               C Because        D As

Answer 1

B

考查連詞用法。A如果；B當(dāng)…時(shí)；盡管；C因?yàn)椋籇因?yàn)椋��?dāng)…時(shí)；句意：盡管因特網(wǎng)對(duì)我們很有益處，但是我認(rèn)為把太多的時(shí)間花在上面并不是一個(gè)好主意。本題的while意為：盡管。故B正確。
