身份询问类

1. 对人提问用who,后接be动词的单复数由主语决定(如Who is she? Who are they?);2. “who's”是who is的缩写,注意其答语需用完整的人称代词+be动词(如Who's he? He's my uncle.)

第二部分 词性转换精讲精练
一、知识点梳理(按规律分类,突破变形难点)
(一)核心变形规律总结
变形类型
例词(Unit 2 重点)
规律总结
人称代词变化
I→my→me; you→your→you; he→his→him; she→her→her; it→its→it; we→our→us; they→their→them
1. 人称代词分主格(作主语)、形容词性物主代词(修饰名词,后接名词)、宾格(作宾语,接在动词/介词后);2. 形容词性物主代词不能单独使用,必须后接名词(如my book,不能说my is book)
名词→复数
parent→parents; brother→brothers; photo→photos; family→families; watch→watches
1. 一般名词变复数直接加s(parent→parents);2. 以o结尾的名词,有生命的加es(watch→watches),无生命的加s(photo→photos);3. 以“辅音字母+y”结尾的名词,变y为i加es(family→families)
动词→名词(人)
teach→teacher; help→helper; work→worker
动词变“执行者”(做某事的人),一般加-er(help→helper, work→worker);特殊变化:teach→teacher(加-er,注意拼写变化)
名词→形容词
friend→friendly; help→helpful; beauty→beautiful
1. 部分名词加-ly变形容词(friend→friendly,注意:friendly不是副词,意为“友好的”);2. 名词加-ful变形容词(help→helpful“有帮助的”,beauty→beautiful“美丽的”)
指示代词变化
this→these; that→those; it→they
1. 指示代词单复数对应:this(这个)→these(这些),that(那个)→those(那些);2. 回答以this/that提问的句子时,用it替代;回答these/those提问时,用they替代
(二)高频易错点提醒
1. 人称代词宾格与形容词性物主代词混淆:“Help me.”(me是宾格,作宾语)vs “This is my book.”(my是形容词性物主代词,修饰book);
2. friendly的词性:friendly是形容词,不是副词,“友好地”需用in a friendly way(如He speaks to me in a friendly way.);
3. family的单复数:表示“家庭”时为单数(The family is big.),表示“家人”时为复数(The family are eating dinner.);
4. 以o结尾的名词复数:photo(照片)、piano(钢琴)等无生命的名词,复数加s;tomato(西红柿)、potato(土豆)、watch(手表)等有生命或特殊的名词,复数加es。
