答案是thickness 怎么改

1 make possible sth =make sth possible
2改为: visible ,我得理解是前面部分省略了 which is
3thick
4when,

25 visibly - visible
    省略pluto which is ，不能是只省略which is 因为which引导从句时是不可能放句首的

最后一道题楼主少写了个s吧
要不就是至少两个错了

11），当make sth. possible和make possible sth.都正确，后者避免头重脚轻。
最后一题,how无法连接两个句子。Strikes前省略了that。
