(water, washing)Peple have cut dwn such a large number f trees that the land changes int desert.We shuld try ur best t stp peple frm cutting dwn the trees.
blwing strngly
The wind utside is blwing strngly.blwing strngly 强劲地吹着风的强烈用strng 修饰。 The strng wind blws. The wind blws strngly.雨的猛烈用heavy 修饰。 What a heavy rain! It rains heavily.
What bad weather!weather的基本意思是“天气,气象”,指某一地区某一时间的具体天气情况,如阴晴、气温、降水、风力、风向等。weather引申可指“处境”。weather是不可数名词,其前不可加不定冠词a,即使前面有bad, gd等形容词修饰时也不可以,但其复数形式可表示“各种天气”。climate, weather都有“天气、气候”之意。 climate指某一地区常年的气候情况,包括气温、降雨量。还可用作比喻。 weather指某地区具体的短时间内的天气,包括晴雨寒暖等情况。The weather lks prmising.天气看起来有晴朗的希望。The climate f China is mild.中国的气候温和。
as a result
As a result, a lt f rich land has changed int desert.as a result 单独使用,后面一般用逗号隔开,并且不能连结2个句子。 He wrked hard at his study. As a result, he passed the exam easily. 由于努力学习,他通过了这次考试。 He defeated all cmpetitrs and wn the schlarship as a result。 他击败了所有的竞争者,最终赢得了奖学金。as a result f:由于 He was late as a result f the snw. 由于大雪他迟到了。
stp … frm ding sth.
Trees can stp the wind frm blwing the earth away. (water, washing)stp frm ding sth 指阻止某人尚未进行的动作stp ding sth 指停止做正在做的事情stp 也可换为prevent 或keep. Nthing can stp/prevent/keep us frm ding that. 当该句型用到动词stp或prevent时,后面的frm可以省略。 I tried t stp/prevent him(frm)smking, but I failed.
Peple have cut dwn such a large number f trees that the land changes int desert.a number f “一些” 修饰可数名词,就像sme ,many, lts f,a lt f那样的.注意a number f修饰的可数名词要用复数形式,be动词也要用复数(即are,具体因时态而定)!可以变成a small/ large/ great number f A large number f students are ill these days because f the flu.the number f ……的数量 谓语动词用单数 The number f the students in ur class is 53.
We shuld try ur best t stp peple frm cutting dwn the trees.cut dwn 表示“砍伐(树木等)”外,还可以表示“消减”、“缩短”等 He tried t cut dwn n smking but failed. They were asked t cut dwn the travel t the frest.cut up :切碎cut ut:切断cut ff:切掉、割掉;砍掉;隔离;阻断;停止,中断(供给)。

in danger f dying ut
Sme animals are in danger f dying ut cmpletely. in danger f … “有…的危险” Hw many factry wrkers are in danger f lsing their jbs?dying 是die的 -ing 形式,此处为动名词die ut 逐渐消亡;灭绝;绝种;(火)逐渐熄灭;(风等)逐渐停止 Ture lve will never die ut and last frever.
cme t d sth.
Human have cme t understand the imprtance f prtecting animals. cme t d sth. “开始做某事”、“逐渐做某事”等。I cme t realize that he is hnest. 但是要注意cme是不及物动词,因此有时后面的t d 表示的是来的目的。Yu’d better cme t jin us.
cme int being
D yu knw hw sandstrms cme int being?cme int being 形成;产生 When did the wrld cme int being? 世界是何时开始存在的?cme int being 是不及物动词短语,无被动形式,不用于进行时态。cme int actin 开始行动 cme int ffice 就职cme int pwer 当权 cme int use 开始使用cme int frce 开始实施;开始生效
smething useful
The gvernment is ding smething useful t prtect the envirnment.smething useful 有用的事情形容词不定代词时,要放在不定代词之后。如: Anything else? There is smething wrng with my cmputer.
Nne f us likes pllutin.nne 可以指人,也可以指物;n ne 只能指人,意思是“没有人”。nne 一般与 f 连用,表示一定的范围;n ne 不能与 f 连用。nne 与数量有关,可回答 hw many/much,表示“一个也没有”;而 n ne 表示“什么人也没有”,可回答 wh。nne (f) 作主语,谓语动词要根据所指代的名词单复数来确定;n ne 作主语,谓语动词只能用单数。
here and there
We shuldn’t leave rubbish here and there. here and there 到处(散落) and 连接一对反义词构成的词组短语还有: up and dwn 上上下下 day and night 日日夜夜 nw and then 时而,时不时 hme and abrad 国内外 war and peace 战争与和平

Dn’t walk n grass r pick flwers.挑选 We must pick the best seeds. 采摘;拾取 Dn' t pick ff any f these flwers扒;剔;挖;掘 Dn't pick yur nse in frnt f me.挑剔 Dn't always pick n everything I did. 接人 I’ll pick yu up tmrrw mrning.
We shuld d everything we can t prtect the envirnment.这个句子中 t prtect the envirnment 是 d everything的目的。而we can 是个省略句,整句话断句: We shuld d everything 主句:我们应该做一切事情 we can (d) 定语从句: 我们能做(事情) t prtect the envirnment. 目的状语:以保护环境
quiet 和 quite
We all need a quiet place t study, but sme students ften make t much nise at schl.quiet /ˈkwaɪət/ adj. 清静的;僻静的;安静的 Culd yu be a little quiet while we are having a class? 我们正在上课呢,你能小点声音吗?quite /kwaɪt/ adv. 非常;相当,很 That questin is quite easy fr me. 对我来说,这个问题太简单了。
Wrst f all, sme f them are quite rude when talking t thers. wrst f all “最糟糕的是” all 表示三者及以上的全部,所以应该用最高级 bad 比较级 wrse 最高级 wrst

Perhaps it will be hard fr us t bey the rules in the beginning, but if everyne des his r her best t fllw the rules, ur schl envirnment will imprve.Sme things we have dne are very gd fr the health while thers are bad.All ver/Arund the wrld, peple have cut dwn millins f trees.Nw many peple in cities have health prblems.T much harmful radiatin frm the sun passes thrugh the hle and reaches the earth directly.
in the beginning
Perhaps it will be hard fr us t bey the rules in the beginning, but if everyne des his r her best t fllw the rules, ur schl envirnment will imprve.at/in the beginning 起初,在开始时。如: He disliked it at/in the beginning. 他开始时不喜欢它。at the beginning f 在……之初,在……开始时。如: She left here at the beginning f this mnth. 她本月初离开这儿了。frm beginning t end 从头至尾。如: He knws the subject frm beginning t end.
Sme things we have dne are very gd fr the health while thers are bad.be gd at 意为“擅长……”,后接名词、代词或ving形式.例如: He is gd at playing chess.be gd with意为“灵巧的;与……相处得好”.例如: She is gd with her hands. He is very gd with the children. be gd t意为“对……友好”.例如: My friend was gd t me when I was ill.be gd fr意为 “对……有好处”.例如: Eating mre vegetables is gd fr yur health.
All ver/Arund the wrld, peple have cut dwn millins f trees.millin与具体数字连用时,习惯上用单数,而且也不后接介词f。 He was prepared t pay tw millin. 但是,当这些词后面的名词有了the, these, thse等特指限定词修饰时,或其后的接的是us, them 这样的人称代词时,则此时必须用介词 f。 Abut three hundred f them have left there. 不与具体数字连用,而是表示不确定的泛指数时,则不仅要要用复数,而且要后接介词f,然后才能接名词。
health prblems
Nw many peple in cities have health prblems.health prblems健康问题health 和prblems都是名词,类似于 apple trees “苹果树”一样,health 是名词作定语.不是healthy prblem, healthy 是形容词“健康的”,而“问题”不存在健康不健康的区别。
T much harmful radiatin frm the sun passes thrugh the hle and reaches the earth directly.用作不及物动词 S+~(+A) I can't reach s high. 我够不到这么高。用作及物动词 S+~+n./prn. When will we reach ur destinatin? 我们何时到达目的地?用作双宾动词 S+~+prn./n.+n./prn. Please reach me the bk. 请把那本书递给我。

It causes the level f the ceans t rise and the climate f the earth t change.cause 表示“造成”“使(发生)”,注意以下搭配: ①其后可直接用造成的结果或发生的事情作宾语。如: Careless drivers cause accidents. 司机不小心就出事故。 ②后接双宾语。如: The car caused me a lt f truble. 这车给我引来了不少麻烦。 ③后接不定式的复合结构作宾语。如: What caused yur wife t change her mind? 是什么使你的妻子改变了主意?
In the passage, blanket refers t carbn dixide arund the earth.查阅或参考 If yu want t knw his telephne number, yu may refer t the telephne directry. 谈到或提到 Please dn't refer t his past again.适用于或涉及到 These bks refer t Asian prblems.
Hw can we avid a serius water shrtage?avid是及物动词,后面可跟名词、动名词,不可接不定式,必须是avid ding sth. 而不是avid t d sth.可用于被动结构.avid的基本意思是避开不希望发生的、不愿忍受的或不想遇上的事情.有时含有先见之明的意味.引申可表示“预防”或“防止”发生某事物.avid所表达的意图总是达成的,否则就须用try.avid指“避免(成功)”,若是企图避免却失败的,不可用avid. They all avided mentining that name. N ne can avid his wn respnsibility.
day by day
Peple’s need fr water is increasing day by day.day by day (逐日地;也是个连续动作,强调一个渐变过程) The prblem is getting wrse day by day.day after day (日复一日一天又一天地把日子看成连续的,隐含着时间长久动作不间断,强调有重复性,每天都在重复一个独立事件) The newspaper jb had me ding the same thing day after day.

The sea seems t have the best answer.3.“It seems+that从句”,其中it是形式主语,that引导主语从句。 It seems that n ne knws what has happened in the park.4.“There+seem t be+名词”,其中t be可省略。seem的单复数形式要根据后面作主语的名词的单复数形式而定。 There desn’t seem t be much hpe f ur beating that team.
We need t take the salt away frm the sea water.带走,拿走。Wh tk away my pen? 谁拿走了我的钢du笔?拆去;移去;拿掉:I suggest yu take the frnt prch away.我建议你把前门廊拆掉。使离开,使离去:Sme urgent business tk me away frm Shanghai.有些紧急事务使我离开上海。【数学】减,减去:38 take away 8 leaves 30. 38减去8剩30。
Pass laws against water pllutin.against作“反对”解时, 反义词是fr。against用在fight,strive,struggle等词后面,同with意思相同,不过against更强调一种困难中的反抗。 We fight fr the weak against the strng. We have saved sme mney against ur ld age.一定要记住 against 是介词,不是动词
