Answer 1

1. Did, do  2. How long  3. is swept  4. enough to  5. that, was

1.     過去式的一般疑問句，謂語動詞為一般動詞，用助動詞did構成一般疑問句，后跟動詞原形do，故本題空格處填Did，do。
2.     對時間長度提問用多長的疑問短語how long，故本題空格處填How long。
3.     被動句的結構為be+動詞的過去分詞，主語為單數第三人稱be動詞用is，sweep的過去分詞為swept，故本題空格處填is swept。
4.     本題的含義為杰克如此的小以至于他不懂這個問題，也就是說杰克明白這個問題還不夠大，enough表示足夠的含義，enough to do表示足以做某事，故本題空格處填enough to。
5.     本題的主語為過去時，從句也用過去時，be的過去式為was，賓語從句為陳述句通常可以加一個關系詞that。故本題空格處填that was。
