参考答案及解析：

1.B Tailor(人名)看起来有些困，他一定是昨天晚上睡觉太晚了。用must have done 这个结构，表示对过去发生动作的一种肯定性的猜测。

2.C 过去将来时态。be to do 在这里表示计划中的行动。Suspend 耽搁，暂停。

3.C 将来进行时态。我不知道明天这个时候Jeanie 在干什么。at this time tomorrow，信号词，说明是明天的这个时候发生的动作，所以是用将来进行时态。

4.B　hardly……when……(一……就……)， hardly后应当用过去完成时，when 后面用一般过去时。hardly 的特殊用法，在其后面跟倒装语序，所以选B。

5.A 过去将来时态。Forgive 原谅，She’d相当于：she　would. 妈妈不知道我看电视花费了多长时间，如果她知道的话，我相信她将永远不会原谅我。

6.A　客观存在，真理性的，规律性的，没有时态变化，都用一般现在时。

7.D　过去进行时态。while是一个信号词，表示一个时间点。

8.D 过去完成时态。发现错误这个动作发生在纠正数据那个动作之前，而改正数据的动作用的是过去时态，所以，发生在过去的过去的动作就用过去完成时态。error 错误。correction 改正，是名词。data 数据。

9.A employer　雇主，老板;or so　大约;promote　提升，升职。通过believed我们看出来，这句话的语境是过去时，提升这个动作发生在过去的过去，用过去完成时。答案就看A，D两个选哪个呢?他的朋友是被提升，所以用被动语态，显然用A被动语态。

10.C　mail　邮件，信件。这是用现在时表示将来时的一种用法。信号词是until.
