1.这句话的意思是在旅游高峰期你没跟旅游团的话,你需要在出发之前提前订票与房间.缺少的词的必须与tickets连起来表示预订票的意思.选项中表示预定的只有D.
2.前面的that是引导定语从句,he visited 用来修饰house,后面的that与it was连起来组成强调句.
3.none at all:一点也没有,表示数量上.not at all：一点也不,表示程度上 ,根据题目问的是有没有.回答没有.
4.倒装句.句型只有A对.Bwhatever用的不对.C.D应该是no matter how late he is.
5,省略句,省略了主语与谓语.
6.the 有强调的意思、
7.根据回答的内容知道是同意观点,B的意思是,我非常同意.
8.WHAT引导的强调疑问句.
9.should 比have to 语气更委婉些.
10.since引导的句子的固定用法.I HAVE DONE STH SINCE ...
11.根据句意,要选择方法,A是手段,B是措施,C,D均能表示方法.其实C,D没有太大区别.只是习惯用法而已.当way意思为“做某事的方法”时,如果后面用不定式,即to do作定语,此时习惯用单数.如果用way的复数时,一般用the ways of doing sth.而approach就不存在这一问题.用作复数时一般也用to do作定语!这不是什么语法规则,就是native speaker的说话习惯.
12.第一个the表示强调.第二个at first sight.是固定短语.
13.Which引导的非限制定语从句、、
