1. 进行时态与always, all the time等连用，表示习惯性行为，且带有浓厚的感情色彩。此处可理解为“你总是丢三落四的”。

2. recently常与现在完成时或一般过去时连用。第二空应用一般现在时。

3. next time引导时间状语从句，而且其谓语动词常用一般现在时表示将来。

4. 由题意“他本来打算在会上发言，但……”可知应选D项。

5. Oh, I was talking to myself.意为“噢， 我（刚才）只是在自言自语”。

6. “乒乓球打得好”是一般情况，故用一般现在时。

9. 现在完成进行时可用于表示动作或状态从过去某一时间开始，一直持续到现在，有可能继续延续下去，也可能刚刚结束。本题使用现在完成进行时强调了动作的持续性和未完成性。

10. 此处用现在进行时来解释前面所说的话，意为“我猜你刚才一定很匆忙，毛衫都穿反了”。

11. 由宾语从句中的would fix可断定第一空用had expected（表示“过去本来期望”）；第二空用had intended（to do...），表示“过去本来打算（去做……）”。

14. 现在进行时可用于表示动作的渐进过程。又如：Her hair is getting grayer and grayer.她的头发正变得越来越花白。

15. 此空用将来进行时表示将来某一时间正在进行的动作。

16. 此处表示“前天之前艾利斯曾经去哪儿了？”故用过去完成时态。

18. Where do you think _____ he...?为双重疑问句，故第一空不填；第二空为过去发生的动作，故用一般过去时态。

22. 按时间表或日程表安排将要发生的事，常用一般现在时表示将来。

23. 题意为“火车将一直以目前的速度行驶直到今晚9点到达山脚下。”

24. 此处prefer意为“宁愿”，是表示人心理状态的动词，不宜用现在进行时态。
