Question

【題目】It has been 3 months________ we had winter vacation.

A.whenB.whileC.sinceD.though

Answer 1

【答案】C

【解析】

句意：自從我們度過寒假以來，已經(jīng)有3個(gè)月了。

考查連詞。when什么時(shí)候，何時(shí)，引導(dǎo)時(shí)間狀語從句；while在…期間，當(dāng)…的時(shí)候，引導(dǎo)時(shí)間狀語從句；since自從，引導(dǎo)時(shí)間狀語從句；though雖然，盡管，即使，引導(dǎo)讓步狀語從句。根據(jù)“It is (has been)+時(shí)間段+since+從句”是固定句型。結(jié)合句意和句型結(jié)構(gòu)可知，此空應(yīng)填since，故選C。
