3.Teacher Delores Clemens is a mother of five and a grandmother.

a mother of five 是名词的所有格形式

's 所有格与of 所有格的用法比较：

(1) of 所有格既可用于有生命的人或物，也可用于无生命的东西。of 所有格有时可以与-’s 所有格互换。如：Mr Smith’s son = the son

of Mr Smith 史密斯先生的儿子Jim’s patience = the patience of Jim 吉姆的耐心 the Queen’s arrival = the arrival of the Queen 女王的到达

(2) 必须用 ‘s 所有格的情形：①表类别时：men’s shoes 男鞋，children’s stories 儿童故事 ②表来源时：John’s telegram 约翰的电报 ③当被修饰的名词后有同位语修饰时：Mary’s husband, a policeman, has just been here. 玛丽的丈夫是个警察，刚刚来过这儿。

(3) 必须用of 所有格的情形：①用于无生命的事物时：the subject of the sentence 句子主语 'Times New Roman'; mso-ascii-font-family: 'Times New Roman'">②表同位关系时：the City of Beijing 北京市③当中心词是名词化的名词时：the life of the poor 穷人的

生活④当of 所有格中的名词后跟有后置修饰语或同位语时：of Mr Smith is a foreign teacher of a university in China. 史密斯先生是中国一所大学的外籍教师。

4.That is higher than other developed countries, as well as some developing ones.

as well as用法

(1)as well as 可连接并列的单词或短语。例如：

It is unpleasant in summer as well as in winter.

夏天不好过，冬天也不好过。

The child is lively as well as healthy.

这孩子既健康又活泼。

(2) as well as 连接两个谓语动词时，它们的时态应保持一致。例如：

He publishes as well as prints his own books.

他的书是他自己印刷出版的。

We are repairing the roof as well as painting the walls.

我们在粉刷墙壁同时也在修理屋顶。

as well as 与动词连用时，其后可用V-ing形式，尤其as well as 位于句首时，此时相当于in addition to。例如：

As well as breaking his leg, he hurt his arm.

他不但摔断了腿，而且还伤了胳膊。

She sings as well as playing the piano.

她不但会弹钢琴，而且会唱歌。

(3) 如果as well as 前面是动词不定式，那么其后的动词也是不定式，但to要省略。例如：

You cannot expect her to do the housework as well as look after the children.

你不可能叫她既照顾孩子又做家务。

(4)由as well as 连接的复合主语并不影响谓语动词的数。例如：

Helen as well as I is eager to see the performance.

海伦和我一样急于要看演出。

I as well as they am ready to help you. 不仅他们愿意帮助你，我也愿意帮助你。
