Dear Sir,
I would like to make a comment on the plastic bags which we use in our daily life.
I thought that the 101 effect（影响）from all these bags on our environment was well –known and that most people know they should not keep 102 them but collect them in the dustbin（垃圾箱）. However, one of the 103 near my home seems to use 104 of these bags than ever before. Red ones, white ones and blue ones -- it 105 no difference. They don't 106 about the problems of environment. They still use plastic bags to wrap（包装）most of the things every day. When I went shopping the other day, I bought two things, and I 107 three bags to wrap 108 . Is it necessary 109 so many bags? Everyone should realize 110 important it is to clean our environment.
Yours sincerely,
Tony Wang
其中的101和104 。
101的答案为bad，但前面有the ，不是要最高级吗？
104的答案为more,但能告诉我有more of these 这中说法吗？还是我理解错了，帮忙纠正下吧。
最后问一下，怎样才可以避免阅读题错误啊？ 不要说空话，套话，要有点实质的！！
