劍橋KET語法全概括(1)一般現(xiàn)在時(shí)+頻率副詞
1. 一般現(xiàn)在時(shí)
一般現(xiàn)在時(shí)是英語語法中的一種時(shí)態(tài),用來表示當(dāng)前的狀態(tài),或者真理性的、規(guī)律性的、經(jīng)常發(fā)生的事實(shí)。比如:
I am a student. (狀態(tài))
I get up at 7:30 in the morning. (規(guī)律性的事實(shí))
提示:
一般現(xiàn)在時(shí)最容易出錯(cuò)的地方有兩個(gè)
1)第三人稱單數(shù)時(shí)動(dòng)詞忘記加s。比較:
John goes to swim in the afternoon.(對(duì))
John go to swim in the afternoon.(錯(cuò))
Does John go to swim in the afternoon? (對(duì))
Do John go to swim in the afternoon?(錯(cuò))
2)提問時(shí)是用be還是用do。比較:
They are students.
提問:Are they students?(對(duì))
Do they students?(錯(cuò))
They like music.
提問:Do they like music? (對(duì))
Are they like music?(錯(cuò))
規(guī)律:
陳述句有be動(dòng)詞的,提問用be動(dòng)詞;
陳述句沒有be動(dòng)詞的,提問用助動(dòng)詞do/does。
頻率副詞
often, usually, always, never, sometimes, normally等都是頻率副詞,也就是表示一個(gè)人做某件事的頻繁程度。在句子中的使用規(guī)律是:
1)有be動(dòng)詞的句子,頻率動(dòng)詞放在be動(dòng)詞后面。比如:
I am often late for school.
2) 沒有be動(dòng)詞的句子,頻率動(dòng)詞放在動(dòng)詞前面。比如:
I always go to school on time.
很多考生搞不清頻率副詞和動(dòng)詞的順序是怎樣的,那就請(qǐng)你記住這個(gè)簡(jiǎn)單的規(guī)則吧。
下一次講現(xiàn)在進(jìn)行時(shí)。很快就回來
