解答 答案:
61.development  考查名词    此处用在定冠词the之后,所以应使用名词;指"工业的发展";故填development;
62.of    考查固定短语     固定短语because of"因为";其后通常跟名词(名词短语)或代词作宾语;故填of;
63.following    考查现在分词   此处在句中作定语,修饰名词reasons并与该名词构成主谓关系,意为:理由如下;故填following;
64.poisonous    考查词形转换以及形容词   此处用来修饰名词gases;所以应使用名词poison的形容词形式,意为:有毒气体;故填poisonous;
65.Besides    考查介词    根据上文已经讲述了三种导致空气污染的原因可知,此处讲的应是除了以上三种原因之外,还有的其原因;except意为"除…之外(不再有)";besides意为"除…之外(还有)";故填Besides;

69.importance  考查词形转换以及名词     此处用在定冠词the之后,指保护环境的重要性;故填importance;
70.be solved   考查语态     分析句意可知,此处的主语the problem与动词solve构成动宾关系;所以应使用被动语态;由于此处用在助动词will之后,并与其构成了将来时态的被动语态;故填be solved.

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(嗜眠发作症).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!

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.
