<6> The mother has bought her daughter a new __ .
A clothes ,B trousers ,C clothing D dress
Ans :D
A,B都是复数，C不可数，题目里面有a new，所以只能接dress，结案。
Of those workers who are able to put some money (28) in
savings , the amount the can save (29 averages) just
6,345 NT a month.
<28> ,A off , B away , C down , D aside
ANS :D
put sth aside是常见的词组，意思是留出（时间）；存（钱）
put sth away则是把…收拾起来
文法可能没错，只是有“存钱”和“把钱收拾起来”的选项时你自己会选哪一个？结案。
The straws reportedly take up to 500 years to rot , and they (33) in the
sea and landfill and contribute to the pollution problem which kills
marine wildlife and leaves tones of litter on beaches .
<33> A caught , B end up ,C finding ,D have left
ANS :B
不能选D的原因是因为吸管是被遗弃的，就算硬要放这边也要用被动have been left，结
案。
<20> ___ we've devoted a lot of resources to locating the cause of
this engineering problem, we're still not sure we understand it very
well.
A In spite of ,B However ,C Nevertheless ,D Although
ANS :D
您的解释是however 定义是无论如何，不管怎样
但是你在翻译时候却把however拆开
正确的翻译应该是
(B)然而，我们想尽办法解决这个问题，我们仍无法完全掌握
(C)尽管我们想尽办法解决这个问题，我们仍无法完全掌握
如果真的想选B
we've devoted a lot of resources to locating the cause of this engineering
problem这句话是一句完整的句子，后面会接句号而非逗号
所以整句会变成
However, we've devoted a lot of resources to locating the cause of this
engineering problem. We're still not sure we understand it very well.
所以B没有办法选，结案。
… respondents say the spend their entire (26) every month.
<26> A bill ,B credit ,C paycheck ,D statement
ANS : C
entire的意思不是全部，而是整体，如果你选A意思会变成花掉“整张”钞票而不是全部
钞票，结案。
