1. all that 这里all 为先行词，that引导的定语从句，that we can do修饰前面的all, 表示所有我们能做的是，这是比较常见的句式 all that we can do is to do sth.
2. 这个要看句子是否完整 he grew up as a child是完整句子，所以缺的是状语，需要用where, 用which的时候会跟着介词，the town in which he grew up = the town which he grew up in
3.定语从句当中，当先行词是最高级，用that来引导，这里the most....是最高级
4.定语从句当中，当先行词是everything, anything等，用that来引导
5.turn to sb. for help是固定词组， 这里是用whom引导定语从句，修饰person,而且把介词放在了whom的前面，本来是 a person whom she could turn to for help, 现在是把to 提前，a person to whom she could turn for help

6.unless it is next Sunday ? 填is 吗？
这里是由unless, if 等引导的条件状语从句，或者until，when, as soon as等引导的时间状语从句，主句用一般将来时，从句用一般现在时表示将来
7.however=no matter how 无论他回来得多晚，他妈妈总是等他回来一起吃晚饭。 这翻译貌似没什么问题吧。。
8.这里是跟one man 对应，虽然more than one man意义上是复数概念，但是形式上是有个one man, 所以后面用has, 自从1979年以来，不止一个人被送到了那里去工作。
9.这种including, except, without, together with sb. 的插入语，直接把它们忽略，要看前面的主语，这里主语是everyone,是单数，所以用goes
10. 这是倒装句，本来是--- The teaching building stands between the two rows of trees
这里stands是谓语动词了， 把 between the two rows of trees提到前面，稍微有点强调作用。

题目稍微有点多。。。其实可以分几次提问的。。。太多了解释部分会缩水
