1.Tom left Shanghai for London on May 5 ,since___I have never called him up.A when B then为何选A、2.The book ___of four chapters.You can begin with the second one directly .为什么要填 consists 而不是 consist.额....第一题就是选when
when可能是指代前边的May 5,应该是一个时间状语从句,用then的话,不应该放在后边吧,since 他很似乎都是放在开头的
book 是单数啊

第一题应该选B then吧，since then自那以后
consist of表示由。。。组成，book是单数所以选用consists

book是单数，所以后面用consists

第一题，选then
第二题， consists 是 consist的第三人称单数形式。book，在这里是单数嘛，修饰它的时候当然用 consists 了！

since when 是“从什么时候开始”，用以表示惊奇或生气，常用于现在完成时态。
since then “从那时以来“，通常与现在完成时连用，指从过去某一时刻起到现在为止的一段时间。因此，第一题用 since then

1. then since then 其后,从此一直
2. consists 主语是单数第三人称，谓语动词用现单三形式
