6、， “給”。 give sth. to sb. “把某物給某人”相當(dāng)于 give sb. sth. 。如： Please give this knife to Zhang Hua. Please give Zhang Hua this knife.(2) Class Four, Grade Seven “七年級(jí)四班”， 英語(yǔ)中一般先說(shuō)小的地方，后說(shuō)大的地方。這就是英語(yǔ)和漢語(yǔ)語(yǔ)序的區(qū)別。7.

9、用于第三人稱單數(shù) he、she、it和單數(shù)主語(yǔ)。 肯定句：主語(yǔ)have / has 賓語(yǔ)。例如：1. I have an English book.2. Lily has a dog. 3.

The pen is red.六、重點(diǎn)講解both have black hair and black eyes.我倆者B長(zhǎng)著黑頭發(fā)、黑眼睛。both pron (與復(fù)數(shù)名詞連用)意為“兩個(gè)，兩個(gè)都”。Both放在be動(dòng)詞，助動(dòng)詞或情態(tài)動(dòng)詞后面，實(shí)義動(dòng)詞的前面。如：

15、Weare both from Sichuan. 我倆都來(lái)自四川。They both work in Toronto.他倆都在多倫多市工作。2 But you look the same.但是你們看起來(lái)一樣。我們沒(méi)有相同的外貌，但我們是We don' t have the same looks, but we are good friends!好朋友！以上兩句中出現(xiàn)了 look the same 與the same looks兩個(gè)短語(yǔ)。雖然是由三個(gè)同樣的單詞組成的兩個(gè)短語(yǔ)，但是由于它們的位置不同，意思就不一樣。look the same 中的look 是動(dòng)詞，意思是“看起來(lái)."

16、;，而 the same looks 中的look 為名 詞，常用復(fù)數(shù)，意思是外表，外貌，樣子”。因此 look the same意為“看起來(lái)很像"，而 the same looks意為“相似的外貌”【鏈接】look at 看.；look like看起來(lái)像。如： Please look at the blackboard. 請(qǐng)看黑板。He looks like his father.他看起來(lái)像他的爸爸。【拓展】look the same的反義詞組是：look different.give this letter to Maria.請(qǐng)把這封信給瑪麗亞。give 給give sth to

17、 sb或give sb sth把某物給某人。因此，此句也可改為：Please give Mariathis letter. 但是當(dāng)用代詞It （它），them（他們）代替某物時(shí)，只能用于 give it/them to sb 結(jié)構(gòu)中。如：Please give it to him.請(qǐng)把它給他。4 . What does she look like意為某人看上去是怎么樣該句常用來(lái)表示對(duì)某人相貌、身材等的提問(wèn)。如：-What does your sister look like你姐姐看起來(lái)怎么樣 -She is tall and thin她又瘦又高。-What do your parents lo

18、ok like你的父母看起來(lái)什么樣一My mother is shortbut my father is tall.我的媽媽矮，但是我的爸爸高。（2） look like .意為看上去像",like 為介詞，意為“像.一樣"。如： Mary lookslike her mother.瑪麗看起來(lái)像她的媽媽。The girl is tall like you.這個(gè)女孩像你一樣高。5 I have blond hair and blue eyes.我有金黃色的頭發(fā)和藍(lán)色的眼睛。She has short brondhair and a small nose.她流著金色的頭發(fā)并且長(zhǎng)

His bag is green.=The green bag is his. Their desks are all he

22、re.= The desk here are all theirs 2. - Whose cat is that那只貓是誰(shuí)的-It is her cat./It's hers.是她的（貓）whose 加一般疑問(wèn)句。（ 1 ） whose 疑問(wèn)代詞，意為“誰(shuí)的”，其后加名詞，再加一般疑問(wèn)句，或如： Whose computer is that= Whose is that computer那是誰(shuí)的電腦（ 2） hers 為名詞性物主代詞，意為“她的（貓）”，其后不在加名詞。3 I think it s Li Ming s. 我認(rèn)為（想）是李明的。（ 1） I think 可作為插入語(yǔ)，通
