閒人蓁妙

    重點1：介係詞by+Ving 的用

    例句：We can make a toy by using things around us.

    = By using things around us, we can make a toy  (藉由利用我們身邊的東西，可以製造玩具。)

    例句：She learns more by asking questions. (藉由問問題，她學到更多。)

    重點2：介係詞used to 的用法

    【句型1】人 + used to + VR → 某人過去經常做某事(而現在不用了) .. used 是動詞

    例句：We used to go to the Internet cafe a lot. (我們以前經常去網咖。)

    【句型2】人 + be,get + used to + Ving→ 某人習慣於做某事(used 是形容詞，to 是介系詞)

    例句：My mom is used to taking a walkafter dinner.  (我媽習慣在晚餐後去散步。)

    重點3：附和句的用法

    1. 原句動詞為be 動詞；附和句也必須用be動詞

    例句： Sam is a student. So am I. (Sam是個學生。我也是。)

    = Sam is a student. I am, too.

    2. 原句動詞為一般動詞；附和句根據時態使用助動詞do, does,或did

    例句： Amy likes fast food. So do we.(Amy 喜歡速食。我們也是。)

    = Amy likes fast food. we do, too.

    3. 原句有情狀助動詞will, can, should,must 或完成式助動詞have；附和句必須用同樣的助動詞

    例句： Jane will play the piano. So will I. (Jane 將要彈鋼琴。我也是。)

    = Jane will play the piano. I will, too.

    重點4： 關係代名詞受格的用法

    1. 當先行詞為「人」時，關係代名詞的受格 : who = whom = that = 省略

    例句：I know the boy ( whom my brothermet yesterday. )

    → whom = who = that = 省略 (我知道昨天我哥哥遇到的那個男孩。)

    2. 當先行詞為「事物或動物」時，關係代名詞的受格 : which = that = 省略

    例句：Do you like the birthday present( which your friend gave you? )

    → which = that = 省略 (你喜歡你朋友送給你的生日禮物嗎？)

    重點5： both？and 的用法

    【句型1】both ？ and

    例句：People want to see both tigers and elephants.

    (人們都想看老虎和大象。) → both + 名詞+ and + 名詞

    【句型2】Both Aand B +複數動詞 (A 與B都………….)

    例句：Both his body and legs were verycold. (他的身體和雙腿都很冰冷。)

    → both…and… 連接兩個主詞，後面一定接複數動詞
