顽强到底共回答了23个问题 | 采纳率87%: 答案是A.
made of..的部分是分词做状语,因为主句主语the machine与made之间是被动关系,所以应该用被动式,如果选项C是having been made of也是可以考虑的.
分词做状语可以相当于一个连词引导的状语从句,这里可以相当于because或者for引导的原因状语从句.
Because the machine is made of plastics,the machine is light in weight.
就算不还原的话,句子依然要翻译成：
由于是塑料做成的,所以这个机器很轻.; 1年前

一篇英语阅读Plastics are materials which are softened by heat and 一篇英语阅读 Plastics are materials which are softened by heat and set into lasting form when shaped in a mold.Some are natural; some are semi-synthetic,the result of chemical action on a natural substance; some are synthetic,built up from the constituents of oil or coal.All are based on the chemistry of carbon,with its capacity for forming chains.The molecules that compose them (monomers) link together in the setting or curing process to form chains (polymers),which give plastics their flexible strength..Some plastics retain their ability to be softened and reshaped:like wax,they are thermoplastic.Others set permanently in the shapes they are given by heat and pressure; like eggs,they are thermosetting.From industrial beginnings in the nineteenth century,plastics have struggled through a hundred and twenty years of glory,failure,disrepute,and suspicion on the slow road to public acceptance.Now,at last,one can positively say that plastics are appreciated and enjoyed for what they are; that they make modern life richer,more comfortable and convenient,and also more fun.Plastics are warm materials,sympathetic to the human touch,and their transformation into things that come into contact with human beings is entirely appropriate.The fact that there are plastics antiques comes as a shock to most people.How can a material that seems so essentially twentieth-century,and one that is so much associated with cheap,disposable products,have a history at all?It is a young technology,and a great part of the fun of collecting plastics is that beautiful pieces of historical interest can still be found very cheap. -------------------------------------------------------------------------------- 1.Which of the following is the best title for the passage? A .Why people Are Suspicious of Plastics B .The Development of Plastics as a Modern Material C .The Importance of Plastics in the Nineteenth Century D .How Plastics Are Manufactured 2.Which of the following is necessary to create any type of plastics? A .Coal B .Oil C .Eggs D .Carbon 3.According to the author,for approximately how many years have plastics existed? A .140. B .120. C .100. D .160. 4.What historical information does the second paragraph give about plastics? A .Their popularity was at its height at the time of the Industrial Revolution. B .The earliest types were soft and did not last very long. C .They have come into general use very gradually. D .They originated primarily as road-surfacing materials. 5.Why does the author mention antiques in the third paragraph? A .Plastic replicas of valuable antiques are relatively common. B .Some plastic objects are now considered antiques. C .Dealers use inexpensive plastic parts to repair valuable antiques. D .Some young collectors prefer real antiques to plastic objects. 七十年代初1年前1: Sophen 共回答了21个问题 | 采纳率71.4%

C find 请参阅以下[考查热点2]
B acted as 这里act as是一个词组表示“担当”,“起.作用”
原句意思是“当一个条形铁块吸引其它铁片,它就起一个磁铁的作用,同时这用吸引作用被称为带磁性”
显然这里没有被动意味,故用主动时态.
D when heated=when it is heated 这里是when引导的一个时间状语从句.英语中在时间和条件状语从句中用一般现在时代替一般将来时.故这里用is.进行时态being heated表示动作正在进行即“正在被加热”,而题意是要说明一个条件,即“一旦被加热,木头会很快燃烧起来产生火焰.”
A let 请参阅以下[考查热点9]
主动形式表示被动含义的用法归纳：
主动语态表示被动含义是学习语态的难点,也是高考考查的热点.现归纳如下：
[考查热点1]
感官动词常用作系动词(如taste,feel,smell ,sound,look,smell等),常用主动形式表示被动含义.例如：
How sweet the music sounds!
The flowers smell sweet．
That sounds very reasonable．
[考查热点2]
某些动词如cut,drive,pay,write,read,sell,keep,prove,weigh,number,drink,wear,pay,wash,open,cost,lock,last等常用主动形式表被动含义,这时常和well,easily,perfectly,badly,slowly等方式副词连用,这种用法多用来说明主语的特征、性质或所处的状态等.例如：
The pen writes quite smoothly．
The book sells well.
[考查热点3] 在too…to结构中常用不定式的主动形式表示被动含义.例如：
It's too good a chance to miss．
[考查热点4]
有些及物动词如cook,burn,print,prepare等有时会用进行时态表示被动含义.例如：
The potatoes are cooking．
The dictionary is printing．
[考查热点5]
在“need／want／require+V-ing”及“bear／stand+V-ing”结构中用动名词的主动形式表示被动含义,这时相当于不定式的被动式.例如：
My car needs／wants／requires repairing．＝My car needs／wants／requires to be repaired．
[考查热点6] 在There be句型中,something,anything,nothing等不定代词以及名词之后的不定式往往用主动形式表示被动含义.例如：
There is nothing to do — I'm bored．
There are six letters to write tonight．
[考查热点7] be+to blame／to
seek等结构具有的特点是作表语的不定式与句子的主语有逻辑上的动宾关系,因而用主动形式表被动含义.例如：
A better way is to seek.
Nobody is to blame for the accident．
[考查热点8]
当不定式所修饰的名词或代词是及物动词的直接宾语,而间接宾语是不定式的逻辑主语时,可以用不定式的主动式代替不定式的被动式.例如：
The teacher gave the students some paper to write on．(the students是to write on的逻辑主语) （some paper 是write on的逻辑宾语）
[考查热点9]
当不定式所修饰的名词或代词是动词的宾语,而句子的主语也是不定式的逻辑主语时,可以用不定式的主动式代替不定式的被动式.若不定式与句子主语或宾语不存在逻辑上的主谓关系,只与所修饰的词有动宾关系时,即只有动作的承受者,没有动作的执行者时,不定式应用被动式.例如：
I have six letters to write today．(write的逻辑主语为I)
This letter is to be written today.
We have a house to let.(let 的宾语是 house)
[考查热点10]
在句型“主语+be+形容词+todo”中,当不定式用在作表语的形容词后作状语,而句中的主语又是不定式的逻辑宾语时,通常用不定式的主动形式表示被动含义.这类形容词有：easy,difficult,heavy,hard,nice,bitter,dangerous,light,interesting．important,expensive,fit,comfortable,pleasant,impossible等.例如：
The picture is pleasant to look at．
The chair looks rather hard,but in fact it is very comfortable to sit on．
注意：当不定式中的动词是不及物动词时,要根据需要补充相应的介词.
[考查热点11]一些介词加具有动作意义的名词构成的介词短语常用来表示被动含义.如：on show／on exhibition,on sale,on fire,out of sight,in sight,under construction,in the charge of,in the posses sion of,under repair,under consideration,under development,under discussion等.例如：
The project is under construction．
His car is under repair．
[考查热点12] 有些不及物动词和词组只有主动形式,常视为用主动形式表被动含义.如：take place,happen,break out,belong to,come out,come about,go up,go out,grow up,consist of,add up to,come into being,come into use,give out,come true,run out,turn up等.例如：
His whole school education added up to no more than one year．
The fire also destroyed cars which belonged to people who worked in the building．
[考查热点13] 形容词worth后用V-ing形式表被动,不可接不定式,但可用be worthy to be done或be worthy of being done形式.例如：
These places of interest are well worth visiting．
These places of interest are worthy of being visited．
=These places of interest are worthy to be visited．
=These places of interest are worthy of a visit．

英语翻译Blow molding is the third largest plastics processing te 英语翻译 Blow molding is the third largest plastics processing technique worldwide and is generally recognized to be one of the fastest growing areas in the plastics industry[1].One of the essential steps which constitutes the blow molding cycle is the inflation of the parison.The entire process of parison inflation occurs in two successive stages,namely,free inflation followed by confined inflation.The parison inflation process is highly complex,involving the interaction of several process variables,such as the inflation pressure,material characteristics,parison thickness distribution,and parison temperature profile. There have been quite a few reports in the existing literaturre on the simulation of parison inflation[2--9].Ryan and Dutta[3] made an analytical treatment of the free inflation of a viscoelastic parison by assuming a one-dimensional isothermal deformation.This simplified analyses cannot be used to predict realistic shapes of the parison during its inflation. The finite element method (FEM) has been used to simulate the inflation of parison over the last decade[4--9].However,modeling blow molding inflation process with the FEM requires that many of the most difficult aspects of the FEM be addtessed in the analysis.These difficulties arise because of large strains,large deformations,nonlinear material behavior and so on during the inflation of parison. In this paper,a mathematical model has been derived for simulating the parison free inflation in the plastics extrusion blow molding.In order to evaluate the predictive capabilities of the model,the instantaneous images of parison inflation within a mold epuipped with glass side windowa have been obtained by using a video capture technique. 1 Theoretical Analysis Consider the free inflation of an isotropic and incompressible annular parison with an uniform radius and thickness,and length 2L in the initial state,as shown in Fig.1.The parison is assumed to be treated as a membrane (with thickness much less than any radius of curvature) so that any change in the deformation variables across the thickness may be neglected.Gravity and surface tension effects are neglected.Cylindrical polar coordinate system(r,r,x) is taken and all puantities are independent of r because of symmetry.Amaterial particle that locates at (r,r,x) during inflation is originally at (r,r,x).The ends of the parison are at x=0 and x=2L,and there is symmetry about the plane x=L. cwhsb1年前1: 口圭口牙共回答了20个问题 | 采纳率90%

1. ___A___plastics,the washing machine is light in weight.
A.made of B.making at C.to making of D. To be made of
选项应该和the washing machine 是主谓关系,所以选A
2. __C____from the hill,the town looks magnificent.
A.seeing B.having seen C.seen D.to see
主语是the town,和see这个词应该是被动的关系,所以选C
3. _A_____that we were late,we began to run.
A.knowing B.to know C.we knew D.as knowing
know发出这个动作的主语是we,独立主格,所以选ing形式.
4. __C____for nearly seven years in African forest,he decided to return home.
A.worked B.working C.having worked D.being worked
主句里decided是过去时,所以前面的从句应该是完成时,而且有标志词for,所以选C
5. ___D___our football ream won in the 12th Asia Games made us very.happy.
A.if B.what C.whether D.that
赢得足球比赛这件事总体做主语,先行词只能是that.所以选D
