题目内容
12．学生应该每天花至少一个小时进行体育锻炼．Students shouldspendat least an hour takingexerciseevery day．
分析 spend； exercise
解答 spend； exercise
根据给出的汉语句子，结合英语的翻译，经过对照后发现英语句子中缺少"花费…"以及"锻炼"的表达，根据spend，take，cost，pay这四个单词都有"花费"的意思，根据该句的主语是students，以及句中"at least an hour""至少一个小时"可知花费的是时间，结合句型结构为sb+…+some time+（in） doing sth可知spend的主语必须是人，可用来指花费时间，且用该结构，故spend符合该句型，该空在情态动词后故用动词原形，又知锻炼的英文表达为"take exercise"其中exercise为不可数名词，故答案为spend； exercise
点评 做类似题首先读汉语句子了解要表达的意思，然后跳过空格再读一下所给的英语部分从而分析出要求翻译的英语，最后填入正确答案并检查，在本题中注意spend，take，cost，pay这四个单词都有"花费"的意思他们的用法区别是答题的关键，以及锻炼的英文表达是"take exercise"
