Answer 1

1. 这里考的是let sb do这个结构，our grandparents who are too old and weak这个作为sb。
2. 这里是个定语从句，environment是先行词，定语句的意思是“在这个环境中”，孩子……，所以用where=in which，在从句中作状语。
3. 这里的than既做better … than的比较句用法，同时也作定语从句的关系代词，与关系代词that所起的语法作用是差不多的，只是在翻译或解释时，要比that多一层比较的意味。另外，由than含有比较意味。
4. 这句话可以翻译为你必须意识到无论你想要谁来完成这个报告，这个人都会承担很多压力来做。无论谁可以是whoever也可以是no matter who，但从句子来看这里填的词不仅要表达这个意思，还做这个句子的主语。而D的话只是兼顾了want sb这个意思，但没有任何人的意思，也不能做主语。
5. 这里考的是make sth + adj.what is impossible就是这个sth，what在这个主语从句中充当从句的主语，而通常that在从句中只作关系代词或连词，没有实际意义。而在此句中明显需要一个主语成分。
6. 这里区分remain to do和remain doing，to do表示有待去做的事情，doing表示保持什么样的状态。从句意看这些问题有待去回答，不过我觉得A似乎更好，因为是问题，所以是被动语态的。
7. Accustomed to是习惯于的意思，后面跟sth，所以是A选项，动名词结构。
8. 这是it seems that的结构，固定搭配，it是虚拟主语。There有那里的意思，与句意、结构都不符。
9. when + doing/done作状语是个结构，即动名词搭配，省略与主句相同的主语，这里的主语是sugar，所以用过去分词mixed，表示被动语态，如果要用D的话，则应该为when it is mixed。
10. 这里用send sth doing sth，B和D从结构上看都是对的，但这里看到时walls of water主动语态摧毁越过了南亚的海岸。

Answer 2

We shouldn't let our grandparents who are too old and weak____along.
你选C大概是受了too...to固定搭配的影响，在这里who are too old and weak是做定语修饰our grandparents的，所以去掉修饰部分，就是We shouldn't let our grandparents live alone.
第二题是状语从句，先行词where还原到从句中就是children are taught how to solve problemsof learning by themselves （in the environment）.
第三题比较句前后成分要一致
第四题题目貌似有问题，应该没有中间的那个you
第五题是宾语从句，make （____is impossible） possible， 括号中应该是个名词，所以用what
第六题你选B应该是受了remain doing的影响，这里hard to answer 是宾补
7.accustomed to doing 意思是习惯了爬陡峭的高山
8.A选项说法本身就不对，It seems that 。。是固定说法
9.这里是状语从句的省略形式，可以说when it is mixed with water,但是若没有it，就只能选A
10. walls of water 与 crash之间是主动关系，所以用crashing
