Question

1.Each of the 400 people received from their boss___gift-----"who moved my cheese?"------_____best-seller in the US-----to understand how to deal with changes in their lives and work.为什么两空都填a，最好能翻译一下
2.Passenger:Look out!There is a kangaroo wandering on the road!
Driver:_____it !That was lucky.It can damage my car really badly.此空为何填Missed,而不填Missing
3.All the task______ahead of time,they decided to go on holiday for a week.
为什么填having been finished而不填had been finished

Answer 1

1.第一个空用a ,是因为话说到这里，我们尚且不知道礼物是什么，属于不定指。第二个空，《谁动了我的奶酪》这是美国的畅销书中的一种。没有采用定冠词the，是因为各时期有自己的畅销书。加了定冠词就意味着《谁动了我的奶酪》是有史以来最畅销的书，可能吗？
翻译：这400人每人都收到了老板给的一个礼物------《谁动了我的奶酪》-----这是美国一本关于如何应对生活和工作中变化的畅销书。
2.这是一个省略句，全句应该是：I missed it !(指刚才没看到)
翻译：乘客：当心！路上有一只袋鼠在徘徊。
司机：刚才没注意！很幸运啊，这东西会把我的车撞坏很严重的
3.这个说起来麻烦，简言之，如果句子中出现2个动词，在没有连词的情况下，有一个是谓语（decided ），那么另一个动词就用非谓语（having been finished）。你如果用了had been finished的话，这显然是谓语动词，但是这个句子里没有连词。
或者这样解释：
All the task having been finished ahead of time,they decided to go on holiday for a week.或
After all the task had been finished ahead of time,they decided to go on holiday for a week.或
When （Because） the task had been finished ahead of time,they decided to go on holiday for a week.或
The task had been finished ahead of time,so they decided to go on holiday for a week.
翻译：所有任务都提前完成后，他们决定度假一周。

Answer 2

1. Each of the 400 people received from their boss___gift.400个人中，每个人都收到了老板送的一份礼物。 具体指“每一个人”。
"who moved my cheese?"------_____best-seller in the US-----to understand how to deal with changes in their lives and work.
《谁动了我的奶酪》是美国一本最畅销书，可以让读者更好地理解她们生活和工作中的变化。泛指“一本”最畅销的书，用a。
2. That was lucky.可以看出，是躲过了。
3. 动词的ing形式表示原因，相当于Because they had finished the task...

Answer 3

1、gift是泛指，前边要用a best-seller（ 畅销书）也是泛指前边用a
2、Missed表过去 动名词Missing要与be动词连用，且放在这里句意不对，下句的That was lucky就表示这是过去时
3、考试是指从过去的某一时间持续到现在，所以用having been finished（现在完成进行时）强调过程；had been finished（过去完成时）强调结果
