5 lasted
我全是瞎写的。。英语不好见谅见谅
我初二

1.a(u开头如果发啊的音用an)
2.imagine
3.how……一般是it cost sb some time orsome money to do sth）
4.has gone(虽然parents是复数，但要注意主语)
5.lasted（持续 后面include是包括）

an university [,ju:ni'və:siti]他的第一个字母u发元音imagine想象意思好似她现在滑冰如此快,很难想象她曾将腿曾受过伤重要想象,而不是知道或者是了解how much these book cost指这些书花了多少钱has gone就近...

1.an university,university是元音开头，所以用an
2.—Look！She’s skiing so fast！
— It is hard to imagine her leg were once broken.
imagine:想象, 设想, 幻想
看她滑雪多快!
很难想像她的腿受过伤。
根据句意是imagine
3.I wonder how much these book cost。
我想知道这些书花了多少钱？
4.Kate，with her parents has gone。
with做连接词谓语动词形式看with前的主语，即临近原则
5The operation on his leg lasted one hour。
他的腿部手术持续了一个小时。
