回答(1):

and的用法
and意为“和,又”,表示顺延或增补:
(1)Our Maths teacher is kind and heipful.我们数学老师和蔼可亲而且乐于帮助我们。(连接连个形容词)
(2)I went to the supermarket and bought some vegetables this morning.今天早上我去超市买了一些蔬菜。(连接两个动词短语,表示意思的顺延,动作的先后发生)
and用作并列连词有多重含义,除了表示并列关系外,还可以表示目的(and之后)和条件(and之前)等关系。
(3)Come and see my family.来见见我家人。(see表示目的)
(4)Be careful,and you will make fewer mistakes.如果仔细,你犯的错误就少)(Be careful表示条件)
but的用法
意为“但是”,表示转折关系,连接意思相反或相对。(1)Our school is small but beatiful.我们学校虽然小但很漂亮。(连接两个形容词,意思相对)
(2)The car is very old but it runs very fast.虽然小汽车旧了,但跑得很快。
.or的用法
意为“或者”,表示选择关系。(1)Which do you like better ,juice or Coke?果汁和可乐,你更喜欢哪个?(连接两个名词)
(2)Do you often go to school on foot or by bike?你经常步行去上学还是骑自行车去上学?(连接连个介词短语)
(3)You can stay here, or you can leave.你可以待在这里,也可以离开。(连接两个简单句)
另外,在否定句中否定并列成分时,用or,而不用and。例如:
(4)I can't speak English or French.我不会将英语和法语。(不能使用and)
英语中,“祈使句+or+简单句”结构,也是一种常用句型。句型中,or意为“否则”,祈使句相当于一个条件,可以和以“if”引导的条件状语从句进行转换。例如:
(5)Put on your coat,or you will catch a cold.穿上你的上衣,否则你会感冒的。
=If you don’t put on your coat,you will catch a cold.(转换成以“if ”引导的条件状语从句时,要去掉并列连词or)
.so的用法
并列连词so表示“因此、所以”之意,常用来连接两个简单句,这两个简单句有意思上的因果关系。(1)The rain began to fall,so we went home.天开始下雨了,所以我们就回家了。
(2)Everyone in the town knew him ,so we had no trouble finding his house.镇上谁都认识他,因此他们毫不费力就找到了他的家。
so和从属连词because(因为)不能一起连用。也就是说,使用了并列连词)。就不用because(从属连词);使用了because,就不用so。
他病了,没去上学。
(3)He was ill,so he didn't go to school
(4)He didn't go to school because he was ill.(
