Unit 4 Hands-on fun 语法+写作解析
一、语法解析
一、祈使句
(一) 定义:当我们向他人发出命令、提出要求或建议时，常使用祈使句。祈使句主语通常不明确表示出来。朗读时用降调。
Eg: Go and ask the teacher.
去问问老师。
Come and meet my family.
来见见我的家人。
(二)肯定祈使句结构:
(1)动词原形(+宾语)+其它
(2) be动词 + 表语(名词/形容词)+其它
(3) let +宾语+动词原形+其它
Eg: Hurry up, please.
请快点!
Be careful, please.
请当心!
Let's play together.
让我们一起玩吧!
(三)否定祈使句:
Don't+动词原形 +其它.
No +名词/动词ing.
Let sb. not do sth.让某人不做某事
Eg: Don't be late.别迟到。
No photos. 禁止拍照。
No smoking.禁止吸烟。
Let's no go there by bus.
让我们不做公交车去那吧。
Should和had better
当我们给他人建议时，可以用should和had better，表示“应该..”或“最好”。Had better语气比should强一些。should和had better都是情态动词，后接动词原型，而且均没有人称和数的变化。
1.should为情态动词，意为“应该、应当”。 Should 否定形式为shouldn't/ should not; should还可表示推测。
Eg: He should work harder.
他应该更加努力工作。
We shouldn't climb mountains alone.
我们不应该独自爬山。
His backpack should be in the classroom.
他的背包应该在教室里。
2.had better 译为“最好”，可缩写成“'d better”，其后接动词原形(不带to的不定式)。含有“应该做”之意，不十分客气，所以一般只用于对晚辈或平辈，不用于对长辈。
肯定式为:had better do sth.译为“最好做某事”
否定式为:had better not do sth.译为“最好不做某事”
Eg:You'd better go to hospital at once.
你最好立即去医院。
You had better not miss the last bus.
你最好不要错过末班公交车。

My favourite DIY activity i s making paper stars. It's easy and fun.
To make them,I need some strips of coloured paper. First, I fold one end of a paper strip into a small triangle, and then keep folding the strip around it to form a five - pointed shape. Next, I push the paper end inside. Finally, I blow gently on the star to make it look 3D.
This activity helps me relax. When I finish making a lot of stars and use them to decorate my room, I feel very proud and happy. Making paper stars is really a great DIY activity!
