"We all tend toerriblyview ourselves like kind and considerate people,says my teacher. "A apology has positive effects.Now we both are exciting to have our friendshipexcited第一处:we前加and/so【解题思路】考查连词。根据逻辑关系可知,“我害怕承认我错了”和“我们很长时间不讲话”之间应该是顺承或因果关系,故用and/so连接两个分句。第二处: run-ran【解题思路】考查时态。根据前后句的时态来看,文章讲的都是过去发生的事情,应该用一般过去时。故将rn改为第三处:删掉much【解题思路】考查固定结构。80,that.是固定搭配,表示“如此……以至于……”。所以此处的much是多余的。第四处:mea→ meals【解题思路】考查名词的数。mea是可数名词,且前面有 several对其进行修饰,故此处应用名词的复数形式。故将mea改为 meals第五处:our→my【解题思路】考查代词。根据上文可知,因为“我”不想承认自己的错误,所以和朋友有很长一段时间不讲话。所以此处是指为“我”的粗鲁行为道歉。故将our改为my。第六处: apologize→ apologizing【解题思路】考查非谓语动词。这里考查 avoid的固定搭配 avoid doing sth(意为“避免做某事”)。故此处将动词 apologize改为其动名词形式第七处: terrible→ terribly【解题思路】考査副词。uncomfortable是形容词,应该由副词来修饰。故将 terrible改为 terribly第八处:lke→as【解题思路】考查介词。view为固定结构,意为“把……看作……,把……视为……”。故应把like改为as。第九处:A→An【解题思路】考查冠词。 apology是可数名词,而且是以元音音素开头的单词,故其前用冠词an。第十处: exciting-excited【解题思路】考查形容词。主语是we,所以应用ed形式的形容词作表语,故将 exciting改为 excited
