[解析]
41. 推理判断题。根据开头Lisa:Hi,Mike!How's your sports day practice going?Mike:Not so good.I think we may drop the ball.(丽莎:嗨,迈克!你的运动会练习怎么样了?迈克:不太好。我想我们可能会掉链子。)结合全文可知,这是一则对话。故选C。
42. 词义猜测题。根据Drop the ball?What do you mean by that?(﹣﹣?你这话是什么意思?)和Mike:Oh,I mean that we may make a mistake or we can't do something well.(哦,我的意思是我们可能会犯错,或者我们不能把事情做好。)可知,"drop the ball"应该是"犯错误"的意思。故选A。
43. 细节理解题。根据Mike:We are practicing for the relay race(接力赛),but we always hand off the baton(接力棒) too slowly.(迈克:我们正在为接力赛练习,但我们总是把接力棒交接得太慢。)可知,迈克的团队传递接力棒的速度太慢。故选D。
