小学英语语法通用版 专项冠军的答案

一般现在时、现在进行时、一般将来时、一般过去时专项练习
\x091）现在进行时——表示说话时正在进行的动作.
\x09动词形式：be +doing 标志性词语：now,look!Look at… Listen!
Example:I am riding a bike now.Look!He is reading a book.
Listen!The children are singing.
What are you doing?I am planting a tree./What is Mary doing?She is skipping.
\x09What are they doing?They are visiting the Art Museum.
Are you painting a picture?Yes,I am./No,I’m not.
Is she /he taking a photo?Yes,she/he is.No,she/he isn’t.
2)一般现在时(Simple Present Tense)常用来表示现在时间里某种动作的经常性和习惯性.动词形式：do/does(第三人称单数) 标志性词语：never,sometimes,often,usually,always,everyday…
例A：I study very hard and Tom studies very hard,too.（我很用功,汤姆也很用功.）
例BThe teacher is not in the classroom and the students are very noisy.老师不在教室,学生都很吵闹.
如例所示:主语为第三人称单数时,一般现在时的动词必须使用第三人称单数形式,其他则除“be”以外都使用原形动词.
\x09
\x09一般现在时的用法如下：文法上一般现在时所指的“现在”,其实其观念并非是绝对的.这里所指的现在是在表明说话时存在着的事物,其时间领域含盖着过去,也将延伸及将来.例如：It is very hot today.（今天天气很热.──如说话时间是在中午,本句话是在表明说话时“天气很热”,实际上“天气热”的现象在中午之前就已开始存在,同时也将延伸到下午.）Dogs bark at strangers.（狗看到陌生人就会吠.──这句话是在谈狗的习性,说话时不一定有狗正在吠,而狗的这种习性可以追溯及远古,当然也将延伸到将来.）
因此,一般现在时常可作用如“today,this + time (this week,this year,…)now,right now,at present,etc.”时间副词来修饰.
3)一般将来时——表示打算在将来做某事.动词形式：be going to do/ will do
标志性词语：tomorrow,next week,this weekend等表示将来时间的词语.
Example:I’m/You’re/He’s/She’s/They’re going to Hong Kong tomorrow.
Are you going to stay there?Yes,I am./No,I’m not.
What are you going to do on Sunday?I am going to play football.
What is Jim going to do on holiday?He is going to stay at home.
Where are you going on holiday?I’m going to the USA.
When will you get there?At about a quarter to ten.
