分析 本文作者主要分析了造成空氣污染的原因以及危害,并且提出了解決污染問題的方法;文中作者講到:隨著工業(yè)的發(fā)展,空氣污染越來越嚴重,在北京,許多人因空氣污染而患上了不同種類的疾。辉斐煽諝馕廴镜脑蛴校河幸话氲脑騺碜攒囕v排放的有毒氣體;25%的空氣污染是由工廠造成的;還有一個原因來自吸煙者;此外,大約 10%的空氣污染是由其他原因造成的;采取的措施:用新的燃料代替天然氣;種植更多的樹木;每個人都應該意識到保護環(huán)境的重要性,做一些事情來停止污染.

解答 答案:
61.development  考查名詞    此處用在定冠詞the之后,所以應使用名詞;指"工業(yè)的發(fā)展";故填development;
62.of    考查固定短語     固定短語because of"因為";其后通常跟名詞(名詞短語)或代詞作賓語;故填of;
63.following    考查現在分詞   此處在句中作定語,修飾名詞reasons并與該名詞構成主謂關系,意為:理由如下;故填following;
64.poisonous    考查詞形轉換以及形容詞   此處用來修飾名詞gases;所以應使用名詞poison的形容詞形式,意為:有毒氣體;故填poisonous;
65.Besides    考查介詞    根據上文已經講述了三種導致空氣污染的原因可知,此處講的應是除了以上三種原因之外,還有的其原因;except意為"除…之外(不再有)";besides意為"除…之外(還有)";故填Besides;
66.should   考查情態(tài)動詞   根據上文講到的污染問題可知,本句的意思應是:我們應該采取一些措施來與污染作斗爭;故填情態(tài)動詞should;
67.against  考查固定短語    固定短語fight against 意為:對抗;反對;與…作斗爭;根據上文可知,此處指的應是:與污染作斗爭;故填against;
68.the   考查固定短語    固定短語take the place of 意為:代替,取代;本句的意思是:新的燃料可以用來代替天然氣;故填the;
69.importance  考查詞形轉換以及名詞     此處用在定冠詞the之后,指保護環(huán)境的重要性;故填importance;
70.be solved   考查語態(tài)     分析句意可知,此處的主語the problem與動詞solve構成動賓關系;所以應使用被動語態(tài);由于此處用在助動詞will之后,并與其構成了將來時態(tài)的被動語態(tài);故填be solved.

點評 語法填空主要考查了各種語法知識在短文中的具體運用.做本題時,需要在正確理解短文的前提下,逐句分析句意以及所考查到的語法現象;因此在平時的學習中,應熟練掌握各種語法知識,其中包括詞法,句法,各種時態(tài)語態(tài)以及虛擬語氣等.

3.Ever tried taking smart drugs to perform better in exams?They certainly work.Before last summer's exam,a few of my mates,merely out of curiosity,took a considerable amount of Modafinil,a drug normally used for narcolepsy(嗜眠發(fā)作癥).Guess what?While I was feeling sleepy,bored by revision,my mates were more focused.
Modafinil is a smart drug that gives a user a feeling of staying awake for hours.It also sharpens the mind,improves memory and helps problem-solving.
But it does more than just keeping you awake.It disturbs your mental system,making you desperate to do what you are doing.You just don't want to do anything else but revise all the time non-stop.
A recent study discovers that healthy people use smart drugs,like Modafinil,to get down to and complete tasks they have been putting off,because these tasks seem more enjoyable when taking these drugs.This might sound like what a stressed student desires.However,the pills have a range of side-effects.
"At present no evidence shows that these drugs are safe in healthy people,"as a medical expert puts it,"Ordering online,though easy,is a dangerous way to obtain drugs.You never know what you're actually purchasing."
In my experience,Modafinil changes people's behavior too.Over those weeks my friends   became different people--in turn aggressive,cold.Even eating became"a waste of time"and so did conversation.
A BBC survey found that of those who had tried smart drugs before,92% would do so again.My friends say they'd happily do so without considering the practice a form of cheating.
I admit I was curious-but not enough to try it.Seeing the strange behavior of other users,I feel a little bit upset and scary.Modafinil may promise to change your grades,but it might also change the way you act.Don't say you haven't been warned!

31.According to the author,his mates took Modafinil for the purpose ofB.
A.escaping from reality            B.getting better exam results
C.curing their narcolepsy          D.leading an active life
32.Taking the smart drug can lead toD.
A.cheating in the exam         B.dropping out of school
C.youth crime                  D.drug addiction
33.How does the author find his males'taking the smart drugs?A
A.Worrying.         B.Inspiring.
C.Acceptable.       D.Reasonable.
34.Which statement about Modafinil is wrong?D
A.Modafinil sharpens the mind and helps problem-solving.
B.Modafinil more than just keeps you awake.
C.Modafinil has a range of side effects.
D.Modafinil is safe in healthy people.
35.Who are the target readers of this passage?D
A.Teachers.        B.Doctors.
C.Scientists.      D.Students.

5.Does stress cause gray hair?Many people believe that tension and stress can cause your hair to lose its color.In fact,it is an old wives tale that being upset all the time can result in premature graying.Here is a closer look at this situation and why some believe that this old wives tale could be true.
As one ages,the hairs on the head also age.In fact,just about everything on the human body begins to show signs of wear and tear after a while.The joints wear and become stiff and skin wears and becomes wrinkled.Hairs on the head grow and eventually die.They are replaced,but in the process something else happens.
When new hairs are replaced,the color or pigment(色素)is also added to them.However,as one ages,this pigment becomes less and less available.At first,hairs will have a limited amount of pigment and they will appear to be grayish in color.In time,they will lose all of their pigment and will be white.Many things are known to cause graying.and genetics is a very powerful factor.If one of your parents turns gray at an early age,there is a good chance that you will too.Some people begin the graying process in high school,while others may be over the age of forty.
Constant worry and tension can have many harmful effects on the human body.It is a known fact that stressful times can cause one to suffer hair loss.It would make sense that if it can cause these problems,perhaps it also may contribute to graying.However,there,is no sound evidence to support this.
On the other hand,many medical professionals believe that there may be a link:between graying and a constant state of anxiety or,tension.Does stress cause gray hair?There is no scientific evidence to support the theory,but it is best to avoid stressful situations.

A.Genetics and the amount of sleeping time
B.The amount of food people eat and living environment
C.The amount of pigment and genetics
D.Genetics and the amount.of water people drink
64.According to the passage,continuous pressure may result inD.
