_______ the Internet is of great help, I don’t think it’s a good idea to spend too much time on it.
A.IfB.WhileC.BecauseD.As
B
B 本題考查連詞的用法。句意:雖然因特網(wǎng)很有用處,但我認(rèn)為在網(wǎng)上花太多的時間不是個好主意。if引導(dǎo)條件狀語從句;because引導(dǎo)原因狀語從句;while和as都可作“雖然,盡管”將,都可以引導(dǎo)讓步狀語從句,但as引導(dǎo)讓步狀語從句時要部分倒裝,while引導(dǎo)的讓步狀語從句用正常語序,且常放在主句的前面。
