Period Three　Grammar Writing Part One　Grammar 用所给动词的适当形式填空 1．Since then，finding (find)ways to grow more rice has been his life goal. 2．As a young man，he saw the great need for increasing (increase)the rice output. 3．Dr Yuan searched for a way to increase rice harvests without expanding (expand)the area of the fields. 4．However，he doesn’t care about being (be)famous. 5．He enjoys listening (listen)to violin music，playing (play)mahjong，swimming and reading. 6．Spending (spend)money on himself or leading (lead)a comfortable life also means very little to him. 7．Just dreaming (dream)for things，however，costs nothing. 8．Over the past half century，using (use)chemical fertilizers has become very common in farming. 动名词 一、动名词作主语的用法 1．动名词作主语往往表示经常性、习惯性的动作。如： Reading is an art.读书是一门艺术。 Writing English novels for him is really great fun. 对他来说写英语小说真有趣。 2．动名词作主语有时也可以用it作形式主语。 用it作形式主语代替动词ing形式，常出现在It is no use/good...doing sth.，It is useful/useless doing sth.等几种句式中。 注意　动名词与不定式做主语时的比较：动名词表示的动作通常是一个泛指的动作；不定式则通常表示具体的动作。 Playing with fire is dangerous.玩火危险。(泛指) Be careful！To play with fire will be dangerous. 小心点！玩火会带来危险。(指一具体动作) 二、动名词作宾语的用法 1．牢记下列用v.ing形式作宾语的动词：admit，appreciate，avoid，consider，delay，dislike，enjoy，escape，imagine，mind，practise，risk，suggest，mention，miss，finish，keep，stand等。 2．动词短语后只能接v.ing形式作宾语的有：can’t help，prefer doing...to doing...，end up，feel like，be busy (in)，prevent/stop/keep ...from...，devote...to，look forward to，pay attention to，be accustomed to，be used to，get down to，stick to，lead to，object to等。 3．在allow，advise，forbid，permit后直接跟动名词作宾语，如果有名词或代词作宾语，则构成“allow/advise/forbid/permit ＋名词/代词＋不定式(宾语补足语)”形式。 4．动词need，require，want意为“需要”时，后跟动名词的主动式或不定式的被动式作宾语，意义没有区别。 5．有些动词和动词短语后跟动词不定式和动名词作宾语皆可，但含义不同。常见的有： 动词 宾语的形式 意义 forget to do 忘记做…… doing 忘记做过…… remember to do 记着要去做…… doing 记得做过…… regret to do 遗憾/抱歉要做…… doing 后悔做了…… try to do 尽力做…… doing 尝试做…… mean to do 打算做…… doing 意味着…… stop to do 停下来去做某事 doing 停止做某事 go on to do 接着做(另外一件事) doing 接着做(同一件事) 三、动名词的复
