I like riding my bike.Though it is not very new,but it is my best friend.I find ∧very convenient to go anywhere with a bike.Riding gives me not only exercises but also pleasure.I use my bike most in summer when the weather is warm and dry.It can be very unpleasant in winter which it is cold and wind is blowingheavy.It can also be very dangerous.Of course I will be very careful in my bike.In fact,accidents are not the only problem.One day I went to school and come back to find the front wheel was missing.It wasthe long walk to the repairer shop.Now I have two strong locks.
解析
1.去掉 but.考查连词.汉语可说"虽然……但是……",但英语习惯上不能相应地说 though…but….(注:不能去掉 though,因为这样还会涉及大小写的改动,而高考短文改错每行只允许改动一处.)
2.find 后加 it.考查代词.此 it 为形式宾语,真正的宾语是其后的不定式.
3.exercises﹣﹣﹣exercise.考查名词.表示"锻炼"时,exercise是不可数名词,所以不用复数.
4.most ﹣﹣﹣mostly.考查单词辨析.most表示"大多数",是代词;mostly 表示"大部分",是副词,所以修饰动词use my bike ,用mostly.
5.which ﹣﹣﹣when.考查定语从句.在句子里修饰先行词winter ,用when做定语从句 it is cold and wind is blowing heavily的时间状语.
6.heavy ﹣﹣﹣heavily.考查副词.修饰动词blowing,用副词heavily.
7.in ﹣﹣﹣on.考查介词.修饰名词my bike,表示"在自行车上",用介词on.
8.come ﹣﹣﹣ came.考查谓语动词的时态.came 与其前的 went 为并列谓语,所以用过去式.
9.the ﹣﹣﹣a.考查冠词.修饰名词 long walk ,表示"一段步行很长的路",用不定冠词a.
10.repairer﹣﹣﹣﹣repairer's.考查名词所有格.修饰名词shop,表示"修理店",用名词所有格repairer's.
