  • 名词所有格

    名词如要表示与后面名词的所有关系,通常用名词所有格的形式,意为"……的".一般有以下几种形式:

    (1).一般情况下在词尾加"'s".例如:

    Kate's father Kate的爸爸

    my mother's friend 我妈妈的朋友

    (2).如果复数名词以s结尾,只加"'".例如:

    Teachers' Day 教师节

    The boys' game 男孩们的游戏

    (3).如果复数名词不以s结尾,仍加"'s".例如:

    Children's Day 儿童节

    Women's Day 妇女节

    (4).表示两个或几个共有时,所有格应加在后一个名词上.例如:

    Lucy and Lily's room Lucy 和Lily的房间

    Kate and Jim's father Kate 和Jim的爸爸

    动物和无生命事物的名词的所有格一般不在词尾加"'s",而常常用介词of的短语来表示.

    a map of China 一幅中国地图

    the name of her cat 她的猫的名字

    a picture of my family 我的家庭的一张照片

    the door of the bedroom 卧室的门

    2.祈使句

    祈使句主要用来表示说话人的请求、命令、建议、叮嘱等意图.祈使句一般不用主语,读时用降调.为使语气委婉、礼貌,常在句首或句尾加please .在句尾时,please前多用逗号.

    (1).祈使句肯定形式的谓语动词一律用动词原形.

    Go and see.去看看.

    Come in,please.请进.

    (2).祈使句的否定形式常用don't于句首.

    Don't look at your books.不要看书.

    Don't play on the road.不要在马路上玩.

    3.There be 的句子结构

    There be是一个"存在"句型,表示"有"的意思,

    肯定句的形式为:There be + 名词(单数或复数)+地点状语或时间状语.

    be动词单复数的确定,看be后边第一个名词,当所接主语为单数或不可数名词时,be动词形式为is;当所接主语为复数名词时,be动词为are;当be动词后接两个以上主语时,be动词与最临近主语保持数上的一致.意思为"某地有某人或某物".如:

    There is an eraser and two pens on the desk.桌子上有一块橡皮和两支钢笔.

    There are two pens and an eraser on the desk.桌上有两支钢笔和一块橡皮.

    (1)there be的否定句,即在be的后面加上not.

    否定形式为:There be + not + (any) + 名词+地点状语.

    There is not any cat in the room.房间里没猫.

    There aren't any books on the desk.桌子上没书.

    (2)there be句型的疑问句就是将be提到句首:Be there + (any) +名词+地点状语?肯定回答:Yes,there is / are.否定回答:No,there isn't / aren't.

    ---Is there a dog in the picture?画上有一只狗吗?

    ---Yes,there is.有.

    ---Are there any boats in the river?河里有船吗?

    ---No,there aren't.没有.

    (3)特殊疑问句:How many ...are there (+地点状语)?"某地有多少人或物?"回答用There be ...

    There's one./ There are two / three / some ...

    有时直接就用数字来回答.One./ Two ...

    ---How many students are there in the classroom?教室里有多少学生?

    ---There's only one./ There are nine.只有一个./有九个.

    (4)如果名词是不可数名词,用:How much + 不可数名词 + is there + 地点状语?

    How much water is there in the cup?杯中有多少水?

    How much food is there in the bowl?碗里有多少食物?
