Can I have some?我可以吃些(食物)吗?some的用法:(用于肯定句),“一些,几个”。例如:I can see some apples on the table.我在桌子上看到一些苹果。(用于疑问句,表示请求,期待肯定的回答)“一些,几个”。例如:Can I have some drink?我可以喝些饮料吗?May I ask you some questions?我可以问你一些问题吗?【注意】some和any与复数名词和不可数名词连用时,表示不确定的数量或程度;否定、疑问句用any。例如:肯定句:I have some flowers.我有一些花。疑问句:Do you have any flowers?你有一些花吗?否定句:I havent any flowers.=I dont have any flowers.我没有花。2. She looked like a white mouse.她看上去像一只白老鼠。 looked like看上去像Jim looks like his father.吉姆看上去像他父亲。【注意】look like 与look the same的区别:A looks like B.= A and B look the same.也就是说,前者的人称在主语和宾语;后者的人称都在主语上,词组后面没有人称。例如:Lucy looks like Lily.=Lucy and Lily look the same.露西和李莉长得很像。3. At four months, she weighed about 10 kilograms and she started to go outside her home for the first time. 在四个月时,她大约重10公斤,并开始第一次出家门。at 用于说明年龄、费用、水平等。at four months 意思相当于when she was four months old。又如:He stopped working at 56. 他56岁时停止了工作。At 20 months , the panda called Xi Wang had to look after herself. 20个月大时,熊猫希望不得不自己照顾自己。 start to do something 开始做某事 如: I started to learn English 5 years ago. 我5年前开始学英语。 It started to rain when I was going out. 我正要外出时,天开始下雨了。4. Eight month later, she was not a small baby any more.八个月后,她不再是一只小幼崽了。 later是late的比较级,副词,(一段时间+ later)用于一般过去时。例如:Two days later, Kate left for Washington.两天后,凯特出发去华盛顿。【注意】介词in+一段时间也表示“再过一段时间”,用于一般将来时。例如: Toms father will be back in two days.汤姆的父亲两天后要回来。later也可以单独使用,“后来,以后”(用于一般过去时或一般将来时)。例如: Later the boy found his father in the city.后来,那个男孩在这个城市找到了他父亲。The others will join us later.其余的人随后就加入到我们中来。notany more(用于非正式文件中),表示“过去曾,现在不再”=no more。They dont have food any more at home.=They have no more food at home.我们家里没吃的东西了。【注意】notany more与notany longer的区别:notany more/no more是强调数量和程度上“没有更多”,做某事在数上不再增加。notany longer/no longer是指时间上不再延长,与连续性动词连用。例如:You will not see him any more.你不会再见到他了。She doesnt live here any longer.她不在这儿住了。5. She grew into a healthy young giant panda and weighed 35 kilograms.她已长成一只健壮的大熊猫了,并且体重达35千克。grow不及物动词“生长,成长,发育”。例如:The rice is growing fine.She grows into a big girl.“渐渐变成”(+表语)。例如:He grew old.他变老了。It grew dark.天色变晚了。及物动词,“栽培、种植”,grow rice 种水稻“养、留”,grow a beard留胡子6. Sadly, it is very difficult for giant pandas to survive in the wild.令人难过的是,大熊猫在野外生存非常困难。It+be+形容词(for sb.)to do sth.“对某人来说做是”。在日常英语中,当主语稍长,而谓语稍短时,常用it作形式主语,而将动词不定式放在谓语动词的后边。例如:It is interesting for us to climb the hills.爬山对我们来说是很有趣的。It was hard for him to pass the exam.他要通过这次考试是很难的。7. Mothers often leave baby pandas for two whole days on their own. 熊猫妈妈们常常不管小熊猫,让它们独自呆着两整天。 leave及物动词,(过去式为left)“离开”He left home in a hurry.他匆忙离开家。“留下,忘带”He left his book in the garden.他把书忘在花园里了。“把留给”Ill leave it to you to buy the ticket.我就把买票的事托给你了。leave+宾语+宾语补足语(为形容词、介词短语、名词等)“使处于状态”。Leave the door open.让门开着。Leave the baby by itself.把婴儿留下无人照管。leave one on ones own “留下不管”,例如:The woman left the baby on its own.这位妇女留下这个婴儿无人照管。8. If people find baby pandas alone, they will take them away. 如果人们发现独自的小熊猫时,会把它们带走。 alone形容词和副词,“独自,单独”He was alone in the house.他一个人在屋里。“仅仅,只有”Man alone has the gift of speech.只有人类有语言的天赋。【注意】alone和lonely的区别:alone表示“单独,独自一人”不含感情色彩。例如:She lives alone, but she doesnt feel lonely.她独自居住,但并不感到孤独。lonely 指人孤独寂寞,也指地方荒无人烟,有浓厚的伤感色彩。例如: She has no friends, she often feels lonely.她没有朋友,常感到孤独。take away “拿走,带走,减去,夺去,使离去”。例如: What takes you away so early?为什么你这么早就要走了?9. make giant panda reserves bigger扩大大熊猫保护区的范围make +宾语+宾语补足语(为形容词、介词短语、名词、过去分词等)“使处于状态(地位)”。例如:Too much homework make him ill.太多的作业使他生病了。Well try our best to make our world more beautiful.我们要努力使我们的世界更加美好。【注意】make+宾语+宾语补足语(为动词原形)“(迫)使某人(做某事)”。例如:They made her wait.他们叫她等。能带宾语补足语的动词常见的有make, keep, find, leave等。如:When he opened the door, he found no one outside.当他打开门却发现外面没有人。The news made her happy. 这消息使她很高兴。You must keep your head cool. 你必须保持头脑清醒。We can make giant panda reserves bigger.我们可以扩大大熊猫保护区。10. encourage farmers to leave the giant panda reserves鼓励农民们离开大熊猫保护区 encourage sb. to do sth.“鼓励某人干某事”。例如:My parents encouraged me to study hard.我父母亲鼓励我要努力学习。11.

If I dont buy them, someone else will buy them.即使我不买,别人也会买的。 else“别的,其它的”作形容词用,通常跟在疑问代词、不定代词后;表示other的意思。例如:What else did he say?他还说了些什么?作副词用,通常跟在疑问副词后,“另外,其它”。例如:Where else did you go?你还去过别的什么地方?13Their number is getting smaller and smaller because their living areas are becoming farmlands.它们的数量日趋减少,因为它们的居住区域渐渐变成了农耕地。smaller and smaller“比较级+比较级”表示“越来越”。例如:He is getting fatter and fatter.他变得越来越胖了。Our country becomes more and more beautiful.我们国家变得越来越美丽。【练习检测】一. 单词辩音:(选出划线部分一个与众不同的选项)( )1.A. wild B. delicious C. dolphin D. squirrel( )2.A. sadly B. male C. kangaroo D. panda( )3.A. hunter B. writer C. farmer D. reserve( )4.A. loss B. polar C. fox D. forest( )5.A. smell B. insect C. encourage D. sell二. 根据句意和中文提示,写出单词的适当形式:1.There are many _(叶子)on the tree.2.Australia is famous for _ (袋鼠).
