(五) 情態動詞can的用法
can表示說話人的主觀看法或語氣｡

1. 表示能力,常被譯成“能”､“會”｡例如:
her sister can speak english. 她姐姐會講英語｡
i can sing english songs. 我會唱英語歌曲｡
2. 表示請求或許可,即常被用來請求對方的許可,或表示說話人自己的許可｡例如:
can i help you? 我能幫你忙嗎?
can you go to the picnic with us tomorrow? 明天你能和我們一起去野餐嗎?
you can sit here. 你可以坐在這兒｡
3. can 的否定式和疑問式
① can 的否定形式是 cannot 或 can not,其縮略形式是 can’t｡例如:
lucy can’t find her story-book. 露茜找不到她的故事書了｡
han mei can’t come to play with us because she is going to the movies.
韓梅不能來和我們玩了,因為她要去看電影｡
② 將含 can 的陳述句變為疑問句時,應直接將 can 移到主語前面｡肯定答語為“yes, 主語 + can.”,否定答語為“no, 主語+ can’t.”｡例如:
—can you see the words on the blackboard? 你能看見黑板上的詞嗎?
—yes, i can. 是的,我能看見｡/no, i can’t. 不,我看不見｡
注意:有時說話人為緩和語氣可以用其他一些詞語作否定回答｡例如:
—can you go swimming with me tomorrow? 明天你能和我一起去游泳嗎?
—i’m sorry, i can’t. i have to visit my grandmother. she is in hospital. 對不起,我不能去｡我得去看我奶奶｡她住院了｡
Module 3 The natural world 篇2
module 3 the natural world
unit 10 forests and land
一、學習目標：
1、認識到森林在生態環境中的重要性，意識到保護森林的緊迫性。
2、知道來自土地的物產和礦產，以及這些物產與礦產的用處。
3、學習用不同的形容詞來描述不同物品的感性特征。
二、重要語言點：
1、provide sth. for sb.“為某人提供某物”，例如，they can provide food for us. 他們可以為我們提供膳食。而 provide sb. with sth. 意為“提供給某人某物”，跟前一個短語意思差不多，所以前一例句可以改為：they can provide us with food.
2、區別：in the tree 和on the tree. in the tree 指本身不屬于樹的東西卻藏在樹里面了，比如人或動物爬到了樹上等。而on the tree是指樹上本來就有的東西，比如果實、化等。例如：the apples are on the tree. 蘋果長在樹上。the cat is in the tree.貓在樹上。
3、介詞with 的用法：1）“用；使用” 。如：they cook food with wood. 他們用木柴燒飯。2）“和…一起”。如：you can go with us. 你可以和我們一起去。3）“帶著”。如：the teacher came into the classroom, with a book in her hand.老師手拿一本書走進了教室。
4、cut down 意為“砍伐；砍倒”。如：do not cut down the tree that gives you shade.[諺語]遮蔭之樹不可伐。
5、lose one’s home “失去家園”。 如：many people lost their homes because of the flood.很多人由于洪災失去了家園。
6、復習：use sth. to do sth.= use sth for doing sth.
7、區別：look for; find與find out. look for “尋找”，強調動作。find“找到”，強調結果。find out “查明真相，弄清緣由”，強調經過費時、周折的調查到最后才得到認證的一種結果。
8、get…from…“從…中得到”，如：we get wool from sheep.我們從羊身上獲取羊毛。
9、區別：be made of 與be made from. 前者表示產品的原材料可以從產品本身看出來（物理的形狀變化），而后者表示產品的原材料無法從產品本身看出來（化學的性質變化）。
10、how does it feel ?感覺它怎么樣？此時how 與what …like意思相近。所以前面一句可改為：what does it feel like? 又如：how does it look? = what does it look like?
11、woolen scarf “羊毛圍巾”。 有時候我們用形容詞來表示物體的材料，如：wooden chair 木椅。我們還可以用名詞來修飾另一個名詞，用來表示材料，如：metal spoon金屬調羹；plastic toy塑料玩具；leather shoes 皮鞋
12、a report on the uses of different materials 一份關于不同材料用處的報告。此處on 意為“關于”，比較正式。
