二、练习
1.答案：B
解析：A项might(可能);B项must(一定);C项need(需要);D项should(应该)。根据前文“just took your temperature and it was very high (我刚刚量了你的体温,它很高)”可知,这里表达的是“一定”的意思,表示肯定的推测,因此B选项符合题意,故本题答案为B。
2.答案：B
解析：recorded记录,录音;canceled取消;followed跟随;accepted接受,都是动词的过去式。根据从句句意"因为我妈妈说我的衬衫太多了"可知,主句为"我取消了订单",要填"取消",其它选项语意不通。故选:B。
3.答案：A
解析：本题考查定语从句中的关系词。分析句子结构可知，行此处"______ were born after 1995"是定语从句,修饰先词Chinese young people，先行词指人，关系词在从句中作主语，应用 that 或 who,且关系词不可省略。故选A。
4.答案：D
解析：cause引起,引发;allow允许;warn警告;encourage鼓励。根据语境,可知4月24日被定为中国航空日,目的是鼓励更多的年轻人相信科学和探索未知世界。故选:D。
5.答案：D
解析：句意:一你知道我们在哪里能找到幸福吗 —我想没有人能给出确切的答案。但是我们选择的生活方式决定了它考查动词辨析。hide隐藏;warn警告;care关心;decide决定。根据“Do you know where we can find happiness ”和“But the way of life we choose...it.”可知,幸福是由我们选择的生活方式决定的,decide符合题意。故选D。
