【答案解析】[解析] 本题考查的是动词forget的用法。forget后面可以跟动名词也可以跟不定式。forget to do something表示忘记做某件还没有做的事情。如：I'll never forget to lock the door. 意思是“我以后不会忘记锁门。”forget doing something表示忘记曾经发生过的事情。如：I'll never forget getting lost in New York.(我将永远不会忘记在纽约迷路的事。)那件事情给你的印象极为深刻，令你不能忘记。请记住：forget doing something常用否定形式，其含义等于remember something。故选项[B]正确。
【答案解析】[解析] 本题考查的是比较级的用法。句中虽然没有出现比较级的标志，但是从对句子意思的理解来看，应该是比较级。“If a car is going very fast, it will travel much longer before it stops.”“如果一辆汽车开得很快，在它完全停下来之前，它还会行驶出更长的一段距离。”这句话潜在的含义是一个行驶得非常快的汽车，与一辆行驶较慢的汽车在完全停住之前所行驶的距离的长短。因此应该用比较级。故选项[C]正确。
【答案解析】[解析] 本题考查的是动词take的用法。某件事情花费多少时间用take。故选项[C]正确。 [知识拓展] spend的意思是“花费时间，金钱”。用法是：①spend money/time，如：We spent $1000 when we were in New York.在纽约时我们花了一千美元。I spent an hour at the station. 我在车站花了一个小时的时间。②spend time/money doing something，如：I spent a lot of time cleaning that room.“我花了很长时间打扫那个房间。”③spend money/time on (doing)something，如：We've just spent ￡1.9 million on improving our computer network. 我们刚刚花了一百九十万英磅加强我们的计算机网络。How long do you spend on your homework?你做功课花多少时间?take也有“花费时间”的意思：It took us all day to drive home. 我们花了一整天的时间才开车回到家。
