study,consider,ponder,weigh区别:
1、study普通用词,指对各方面考虑,在制订出计划或采取具体动作之前作认真检查。
2、consider既指一时的对某事的考虑,也指长时间的深入的思考。
3、ponder侧重仔细、深入、连续地考虑问题,以作出认真的估计和正确的抉择。
4、weigh指作出决策前把问题的各个方面进行比较,权衡利害得失,取有利的方面。
改为否定句是:We are not in the study.
一、英语改否定句方法:
1.有系动词be(am,is,are,was,were)的,在后面加not;
2.有情态动词can,may,must等的,在后面加not;
3.已经有了助动词的,在后面加not;
4.没有前面三种情况的,要用到助动词do,does,did加not,放在动词原形前面;
5.特别情况,有些句子本身有不定代词做主语或者宾语了的,可以把不定代词改为否定就可以。
二、修改否定句实例
①如果句子中有be动词、情态动词和助动词时可以再be动词、情态动词和助动词后加not
例如:I am a teacher.→I am not a teacher.
She can help me.→She can't help me.
Yes,I do.→No,I don't.
②如果句中谓语动词为行为动词时,要根据时态选用do的相应形式,把肯定句变为否定句。
例如:The little girl wants to go there.
→The little girl doesn't want to go there.
He did his work yesterday.→He didn't do his work yesterday.
三、知识点拓展
①如果是祈使句变否定句时,一般在句首加Don't,但Let us或Let's开头的祈使句在 Let us或 Let's后加not即可。
例如:Put them over there.→Don't put them over there.
Let us go home.→Let us not go home.
②如果主从复合句中,主句是I think,I believe等结构,变否定句时,形式上否定主句,实际上否定从句。
例如:I think chickens can swim .我认为鸡会游泳。
→I don't think chickens can swim .我认为鸡不会游泳。
③如果句中有“had better +动词原形”,变否定句时为“had better not +动词原形”。
例如:You'd better go to school.→ You'd better not go to school.
动词不定式变否定式时,常在不定式to前加not。
例如:The teacher tells me to do it.→The teacher tells me not to do it.
④如果句中有使役动词和感官动词(make,let,hear,see,watch等)后接省略to的不定式,此种不定式变否定句时只需在省略to的动词原形前加not。
例如:I saw her work.→I saw her not work.
