Question

That’s all for the introduction to your arrangements these days. So now ______ there are any questions, I’d like to go ahead and start the first video.

A．if

B．unless

C．until

D．though

Answer 1

B

試題分析：A.假如B.除非…否則C.直到D.盡管 句意：這些就是這幾天對(duì)你安排的介紹。現(xiàn)在除非有問(wèn)題，否則我就去開(kāi)始播放第一個(gè)視頻。故選B
點(diǎn)評(píng)：本題較易，重在理解文中的上下關(guān)系，可以用排除法，將每個(gè)選項(xiàng)帶入，選出意思通順的一項(xiàng)即可。
