Answer 1

分析 本文叙述的是骑自行车的优点．
随着人们生活水平的提高，汽车成为人们的主要交通方式，可是这也造成了一些问题，例如空气污染和交通阻塞．我认为骑自行车是一个好的解决办法，这种方式既不需要汽油而且能够锻炼我们的身体．所以加入我们骑车的队伍吧．

解答 As is known by all，with the improvement of people's living standards，cars have become a popular means of transport，bring great convenience to our life．However，they have also caused some problems such as air pollution and traffic jam．
How can we solve these problems then？As far as I am concerning，riding bicycles is a good solution．For one thing，bicycles don't need any petrol but they are energy-saving．For another，bicycles are environmentally friendly because of they won't give off waste gas．Beside，riding bicycles is a good way for us to exercise and it is beneficial to our healthy．
As result，let's take the responsibility to build up a low-carbon city by riding bicycles．Come on and join them．
解析：
1．by-to．考查介词．固定句式As is known to all 表示"正如人们所知"．
2．bring-bringing．考查非谓语动词．bring great convenience to our life是结果状语，是一个必然的结果，所以用现在分词bringing．
3．jam-jams．考查名词．jam是可数名词，根据 some problems 可知用名词复数，表示"交通阻塞"，所以用jams．                                                                
4．concerning-concerned．考查固定句式．固定句式As far as I am concerned表示"就我而言"
 5．去掉of．考查介词．because of 和because都表示原因，但是前者连接单词，短语和what从句，because和句子连用，本题里用的是句子 they won't give off waste gas．，所以用because
6．but-and．考查连词． bicycles don't need any petrol 表示"自行车不需要汽油"； they are energy-saving．表示"它们是节能的"，两句之间是并列关系，所以用and连接．
7．Beside-Besides．考查单词辨析．Beside表示"在旁边"；Besides表示"此外"．riding bicycles is a good way for us to exercise 是对上句的进一步的说明，所以应该用Besides．
8..healthy-health．考查派生词．做is beneficial to的宾语，用名词 health，表示"我们的健康"
9．As和result之间加a．考查冠词．固定短语As a resultlet表示"结果"．
10..them-us．考查代词．和上文let's take the responsibility to build up a low-carbon city by riding bicycles．呼应用us．

点评 考查短文改错．
一致关系是短文改错的主要考点，例如人称一致，主谓一致，并列连词的前后词形词性一致等等．例如本题里的第十题就是人称的一致．
