20、esent there are not many milu deer in nature parks in China .We use this tense to show that something is being done at the present time .For the present we do not need that book , so please go on reading it yourself .2 . one day ; some day ; the other day明晰这三个短语都可表示“某一天”，但用法不同。( 1 ) one day 可指过去或将来的

21、某一天，some day 只能指将来的某一天，the other day 指过去 ( 不久前 ) 的某一天。如：At all these centres it is hoped that one day they will have enough animals to set them free and let them live in the wild again .Youll be an engineer some day .I met him the other day at the bus station .( 2 ) 这三个短语通常作状语用，但 one day 间或能作主语用。如：O

22、ne day on the moon is as long as two weeks on the earth .( 3 ) one day 不能连写成一个词。而 some day 有时可连写成 someday。如：Someday we may drive cars that are run by electricity .3 . greatly ; very ; much明晰这组副词都可作“特殊”解，主要区分是：( 1 ) greatly 修饰动词或过去分词。如：Since then the number of milu deer there has greatly increased .(

23、 2 ) very 修饰形容词和副词原级，不能修饰动词和 a - 形容词。如：I think hes very old .( 3 ) much 修饰动词、过去分词、形容词和副词的比较级或级。如：We like it very much .Now it is much easier to make plans for our trips .当修饰过去分词时，much 有时可与 greatly 互换，但 greatly 的语气比较强。如：He was greatly moved .4. would like的用法明晰would like 用以表示说话人委婉的愿望或恳求。意为“期望，想要”等。其中

24、would( 适用于各种人称 ) 可以换成 should ( 只限第一人称 ) 。在口语中，常用其缩略式“ d like”。其否定式为“主语 + shouldnt/wouldnt like + 其它”；其疑问式为“Would + 主语 + like + 其它 ? ”。would like 主要有如下四种结构：1) would like +名词或代词。 Would you like some coffee ? 你要些咖啡吗 ? Yes , please . 是的。 Would you like another cup of tea ? 你还要一杯茶吗 ? No , thanks . 不要了，感谢

25、。2) would like + 不定式。 Would you like to have some rice ? 你要米饭吗 ? Yes , Id like to . 是的，我要。 Would you like to have some more beer ? 你还要些啤酒吗 ? No . thanks . Ive had enough . 不要了，感谢。我喝够了。 Wound you like to go with me ? 你情愿和我一起去吗 ?3) would like + 主语 + 不定式 ( 作宾补 ) 。 Would you like something to drink now

26、? 你现在想喝些什么吗 ? Id like a glass of beer . 我要一杯啤酒。4) would like +不定式的完成式。该结构含有责怪或惋惜的意味。表示过去本该做某事但未能去做。Wed like to have helped her . 我们本该关怀她。Youd like to have gone there yesterday . 你昨天本该去那里。5. Where are you travelling to , Gary ? 加里，你们预备到哪里旅行 ?明晰该句用现在进行时表示将来，指按方案、支配在不久就要发生的动作，常用在口语中。常见的这类动词有 come , go

27、, leave , arrive , get , start , travel , work , stay , try , fly , return 等。例如：How are you getting there ? 你们预备怎样到那里。6 . Good luck with your trip ! 祝你们旅途好运 !明晰Good luck . 是分手道别时的常用祝愿语，意为“祝幸运/平安/顺当”，其后常跟介词 to ( sb . ) 或 with ( sth . ) 。又如：Good luck with your new job !Good luck to you !7 . Until rece

28、ntly , the only milu deer alive in the world belonged to 直到不久以前，世界上仅有的活着的麋鹿属于明晰 ( 1 ) until recently 意为“直到不久以前；直到最近”，until 在此相当于 till , 其意思是“直到为止”，可作介词或连词，until 在此为介词。作介词时，其后常跟表示时间的名词，也可跟副词。作连词时，引导一个时间状语从句。例如：I taught in No . 58 Middle School of Zhengzhou until 1993 .Father usually doesnt go to bed

29、until very late . 爸爸通常很晚才睡觉。( 2 ) alive 意为“活着的；在世的”，相当于 living 或 live ( adj . 活着的 ) ，它属于表语形容词，即只在句中作表语，不作定语。但 alive 间或可以作定语，要放在它修饰的名词之后。例如：Who is the greatest man alive in the world now ?living 和 live 作定语时，需前置。例如：living thing 生物，live chicks 活鸡8 . In fact , there are so many deer that some are being

30、sent to nature reserves by environmentalists who would like to return them to the wild . 其实，现在这种麋鹿已经相当多了，有一些正在被送往那些情愿把麋鹿送回野外去的地方。明晰 ( 1 ) 该句是一个较为简洁的复合句，主句为there are so many deer , that 引导的是结果状语从句，which 引导定语从句。在这个 sothat 结构中，中心词是名词 deer，本应当用 suchthat 结构，但因名词前有 many 修饰而用了 sothat 结构，此特殊用法需留意。( 2 ) are

31、being sent 是现在进行时的被动语态形式，表示“正在被送往”其中的 being 简洁被误省。又如本课中的其它两句：The life of the milu deer is being studied there .More milu deer are being moved to a new large nature park in Shishou in Hubei Province .【妙文赏析】Two MistakesFor a long time Dr Smith had wanted to get a better job in a certain big modern hos
