答案以及解析
一、单选题
1.答案：B
解析：考查介词辨析。句意: —妈妈, 快看, 有一只可爱的小鸟。—Alex, 它是刚才通过窗户飞进我们厨房的。across指从物体的表面穿过; through是从物体的内部穿过; above在物体的上方; under在物体的下面。结合语境可知选B。
2.答案：B
解析：----你的微信账户安全吗 ----是的，连我父亲也不能用除非我告诉他密码。when"当……的时候"；unless"除非"；while"当……的时候"；if"如果"。
3.答案：A
解析：考查宾语从句。句意: —我想知道明天是否会下雨。—我不确定, 但我希望如此。已经干旱了两个月了。根据下文"It has been dry for two months."可知, 此处宾语从句应询问"明天是否会下雨", if在此意为"是否", 故选A。
4.答案：D
解析：—你在你们学校是个篮球运动员吗 —是的三年前我加入了这个队。由答语中的"3 years ago"可知,应用一般过去时。 主语I和动词join之间是主谓关系,应用主动语态,故选D。
5.答案：D
解析：句意:她太忙了,即使她想和儿子在一起,也抽不出足够的时间。before“在……之前” ;as if“好像”;because“因为”;even if“即使”。
