C 考查情态动词。根据句子，指的是过去的情况，所以要用情态动词加完成时态表过去本应该做而实际没做的事。might have done,本可以做某事；ought to have done本应该做而实际没做。句意：玩电脑游戏花费了这个男孩大量的时间，他本应该把时间用在功课上。所以选C。
在记忆英语单词时，还是要尊重英语单词的内在规律，探索自己的记忆方法。任何偷懒投机行为都会是竹篮子打水一场空。莱曼英语推荐给大家的单词记忆方法是现实可行的，但必须持之以恒，不懈努力，才能达到一个良好的效果。
1.模仿默念：
这是学好英语的第一要素。无论听英语课，还是和别人用英语交谈，还是看美国大片，一定要养成良好的模仿，跟读，默念的习惯。这样，无形中就在帮助你复习旧单词和学习新单词。可惜的是，大部分中国学生没有这方面的养成教育。孤立地背诵一个单词，绝不会在综合运用的句子中能够理解它。
2.字母组合：
英语单词中的字母组合犹如汉语中的偏旁部首。学生在学习英语单词，记忆英语单词时，一定要学好英语的字母组合。所谓的字母组合，即元音字母与辅佐其发音的辅音字母的固定组合。如；ea,ow,ou,ci,ight,tion等。根据莱曼英语的教学实践，英语常用的固定字母组合近70组，可覆盖百分之八十以上的英语单词。
3.节奏韵律：
生活的实践经验告诉我们，那些有节奏有韵律的东西，诸如顺口溜，歇后语以及唐诗宋词，都比较利于人们记忆。所以，当我们记忆背诵单词时，应根据自己的情况并兼顾到英语的字母组合，将其进行分段，使其具备节奏或韵律，如；sta,tion/gir,l/dic,tion,ary/vo,ca,bu,lary/。以上的单词是通过逗号进行了分段，便于这些单词的记忆。（station/girl/dictionary/vocabulary)
4.联想记忆
当我们在审视一个英语单词时，就会发现它会与其他单词产生一些联想，利用这些联想帮助记忆不失其为一种智慧。
（1）词中之词:
meat中含有eat transport中含有sport
cat 中含有 at chair中含有air和hair
（2）含义相关：
boy/toy;男孩玩玩具
cook/book;烹饪之书
slow/low;慢而低沉的声音
paste/taste；糨糊的味道
5.广泛阅读
英语学习中强调广泛地涉猎不同类型的知识，这对于将英语的语言能力发挥到及至起着非常重要的作用。针对英语单词的学习而言，广泛地阅读课外英语书籍可使大量单词无数遍地得以重复，这对于永久记忆单词起着不可替代的作用。可惜的是，大部分中国学生很少主动地阅读课外英语书籍。这种课外阅读的匮乏，是对英语单词的扩充极为不利的。
6.交流运用
要想扩充或牢记英语单词，除了作业之外，必须充分利用各种机会和各种媒介大量练习英语，包括听，说，读，写，译，全面地为自己建立一个英语语言环境。在不断地运用中使得高频率单词得以大计量的重复，从而达到记忆的一劳永逸。网络聊天，每天日记，电影欣赏，英语歌曲，与老师沟通等均不失为很好的方法。
7.字典查阅
查字典，看字典，读字典，甚至背诵字典，抄写字典是每一个英语学习成功者曾经或多或少地实践过的单词学习方法。试问，英语不理想的学生，你何曾认真地阅读过字典呢？哪怕是其中的一个词汇条目，你是否认真地从头到尾地阅读过？
一.时态概论：
所谓的英语时态就是动作发生的时间不同，要用不同的动词形式来表达。因而，英语时态的驾驭和掌握必须以动作发生的时间为根本，进行判断，从而来进行时态的选择。英语中，常用的时态共计十种。根据现行的学校教材安排，英语时态被分成下列三个阶段：
小学：四种
初中：四种（兼顾复习小学所学的四种）
高中：二种
重难点在于各种时态之间的区别，综合运用以及动词形式的记忆。
二.时态分类：
英语时态按下列名称分类为：
现在时态 过去时态
一般现在时 一般过去时
现在将来时 过去将来时
现在进行时 过去进行时
现在完成时 过去完成时
现在将来进行时
现在完成进行时
以上各时态平起平坐，无任何顺序排列而言。也即，它们是同等的重要和常用，不应厚此薄彼。
三.学习方法：
莱曼英语在多年的教学实践中，一直奉行方法领先的教学原则。在教授英语时态时也不例外。只有这样，才能使学生概念清晰，才能使学生在学完时态以后，娴熟地将其转化为能力。莱曼英语根据英语时态的内在规律，推出英语时态的“五点论”学习方法：
1.含义：每一种时态独有反映其内在规律的含义。
2.中文线索：每一种英语时态都会有相应的中文时间定位。
3.构成：每一种时态都有其独特的构成，或被称为时态句型。
4.助动词：时态不同，助动词也就不同。帮助构成问句和否定句。
5.时态例句：通过例句，掌控不同的时态，使其娴熟起来，区别于其他时态。
四.各时态例句展示：
1.一般现在时：
I always swim in the afternoon.It is usually sunny.
He always swims in the afternoon.He feels very relaxed.
2.现在将来时：
I will swim tomorrow afternoon.I am not going to have any classes.
He will swim tomorrow afternoon.He is going to have a swimming test.
3.现在进行时：

4.现在完成时：

5.一般过去时：

6.过去将来时：

7.过去进行时：

He told us on the phone that he was swimming in the lake.And he wanted to continue.
8.过去完成时：
I had already swum for half an hour when he came to the swimming pool.Then he joined us.
He told me that he had already swum for more than an hour.And he had never relaxed like that.
9.现在将来进行时：

He will be swimming in the sea of Hawaii this time next year.I hope he will have a good time there.
10.现在完成进行时：

以上是莱曼英语为大家粗略总结和对比了一下英语中常见的时态例句。至于各种时态的详尽解说，将安排在下一讲中，希望大家予以关注。
It was the third time that he had told us about his story.
这是固定句型。it is the first/ second/ third time that sb. did sth. 这是某人第几次做这件事情了。
如果be动词是一般现在时，从句中的谓语动词用过去时。
如果be动词是过去时的话就用过去完成时。
所以选B
是个固定句型，好长不看了，不知道对否，前面过去式的话从句就要用过去完成时；前面是一般现在时态从句用现在完成时态仅供参考，这是个固定句型阁下可以记住
选B
类似例句有：
It was the third time that he had been out of work that year.
这是他那一年第三次失业了。
