2.名詞性物主代詞相當于一個名詞, 作主語, 表語, 賓語

　　　 　　a. His brother is a driver; mine is a worker.

　　　 　　b. These books are mine.

　　　 　　c. You can use my bike and I may use hers.

1.形容詞性物主代詞相當于一個形容詞, 作定語, 如: our work, her students, their house

3.關于人稱代詞用法需注意的問題:

　　 ①.在than / as引導的比較狀語從句中常有省略, 注意其中的人稱代詞作主語用主格, 作賓語用賓格. 在這類從句中, 在不引起誤解的情況下, 有時用賓格代詞代替主格代詞

　　　 　　a. He likes Mary better than I ( like Mary ).他比我更喜歡瑪麗

　　　 　　b. He likes Mary better than ( he likes ) me他喜歡我,更喜歡瑪麗

　　　 　　c. He is taller than I / me.

　　 ②.在強調句中, 若被強調的部分是代詞, 則其格不變, 如:

　　　 　　a. It was I who first opened the door this morning.

b. It was me whom they talked about.

　 　③.人稱代詞單獨使用或是在not之后, 常用賓格

　　　 　　a. “ I like English. ” “ Me too.”

　　　 　　b. “ Would you like more wine ?”　 “ Not me.”

　 　④.在同位語中, 人稱代詞的格視與之同位的詞在句中的成分而定, 如:

　　　 　　a. We, Tom and I, showed her many wonderful pictures.

　　　 　　b. She showed us, Tom and me, many wonderful pictures.

　 　⑤.人稱代詞在代替一些不定代詞, 如: anybody, everybody, anyone, someone, no one, whoever及person等這些無明確對象的代詞或名詞時, 在正式場合用he / his / him代替, 在非正式場合用they / them / their代替, 如:

　　　 　　a. Nobody came, did he/they ?

　　　 　　b. Whoever comes, tell him / them the news.

⑥.在be或to be之后的人稱代詞的格應根據它所指代的名詞或代詞在句中的成分而定

　　　 　　a. I thought it was she. / I thought it to be her.

　 　　b. I was taken to be she.我被當成了她. / They took me to be her.他們把我當成了她

⑦.在口語中常用賓格代詞作表語

a. “ Who is that ? ”　 “ It is me. ”

⑧.they可指“有關的人” “人們”, 相當于people, 如:

　　　 　　a. They say the fire broke out at midnight. = People say the fire broke out at midnight. / It is said that the fire broke out at midnight.

　 　⑨.三個人稱代詞同時出現時, 其順序一般是: 你, 他/她, 我; 我們, 你們, 他們

　　　　 a. You, he and I all enjoy music.

物主代詞

表示所有關系的代詞稱為物主代詞

2.賓格的用法: 作及物動詞的賓語或介詞的賓語.

　　　 　　a. Mr. Li teaches us English.

　　　 　　b. We often go and see her on Sundays.

　　　 　　c. You are really above me in maths.

2． 初步了解廣義相對論時空結構及重要實驗觀測證據

[教學重點]

了解廣義相對論“等效原理”

[教學難點]

物質的引力使光線彎曲

[疑點]

是引力使時空發生彎曲還是時空彎曲使物體受到引力

[易錯點]

光在真空中一定沿直線傳播

[思想方法]
