The inhalation (吸入) of asbestos particles is associated with a number of lung diseases, such as asbestosis and ___50___ cancer.
Asbestosis is caused by the entry of asbestos particles into the wall of the alveoli, causing scarring which limits the functioning of the lungs. The lung ___51___ its elasticity and may change shape. The initial symptoms of asbestosis are a tightness in the chest and breathlessness. In its ___52___ stages, sufferers develop the barrel-shaped chests associated with emphysema, cyanosis, (where the skin takes a bluish ___53___ ) and club fingers.
Lung cancer, the generic ___54___ for malignant tumors（肿瘤）of the alveoli and bronchial tubes, has been shown to be directly ___55___ to the inhalation of asbestos particles. As in the case of asbestosis, there is generally a period of inactiveness which may ___56___ from 25 to 30 years after initial exposure, despite the ___57___of further exposure. Research suggests that there is a direct correlation between the degree of exposure to asbestos ___58___the incidence of lung cancer. Where exposure occurs, the level of risk is further ___59___ by cigarette smoking. Asbestos workers who smoke cigarettes have a 90% greater risk of catching lung cancer than workers who do not ___60___.
Exposure to blue asbestos has been shown to producemesothelioma, a rare cancer of the outer lining of the lung or pleura. In a normal population the incidence of mesothelioma is extremely ___61___. Where epidemiological surveys have revealed a higher incidence of the disease, it is almost always related to ___62___ exposure.
___63___ changes in lung tissue caused by exposure to asbestos are pleural plaques and effusions. The former refer to a thickening of the lining of the chest wall, ___64___ the latter consists of a collection of fluid in the chest region outside the lungs. Pleural plaques commonly remain undiagnosed and generally have no detrimental effect on health.

When I was growing up, I seldom heard the words “I love you” from my father. If your father never 1 them to you when you are a 2 , it gets more and more 3 for him to say those words as you get older. To tell you the truth, I could hardly 4 when I heard those words from my father. Neither could I remind when I had last said those words to 5 . I decided to 6 my shyness aside and make the first move. 7 hesitating for some time, in our next 8 conversation, I spoke out the words suddenly, “Dad ... I love you!”
There was a 9 at the other end. It wasn’t after a while did he awkwardly(笨拙地) reply, “Well, 10 to you!” I laughed and said, “Dad, I 11 you love me, and when you are ready, I know you will say what you want to say.”Fifteen minutes later my mother called and 12 asked, “Paul, is everything okay?”

I recently heard a story about a famous scientist who had made several very important medical breakthroughs（突破）. He was being interviewed by a reporter who asked him 1 he thought he was able to be so much more 2 than the average person.
He responded that it all came from a(n) 3 with his mother that occurred when he was about 2. He had been trying to 4 milk from the fridge when he 5 the slippery(光滑的) bottle, its contents running all over the kitchen floor.
When his mother came in, 6 shouting at him or giving him a lecture, she said, “Robert, what a great and wonderful 7 you have made! I have 8 seen such a huge pool of milk. Well, the damage has already been 9 . Would you like to get down and 10 in the milk for a few minutes before we clean it up?”
Indeed, he did. After a few minutes, his mother said, “Robert, whenever you make a mess like this, eventually you have to restore everything to its proper order. So, how would you like to do that? We could use a sponge(海绵), a towel or a mop. Which do you prefer?” He chose the sponge.
His mother then said, “ You know, what we have here is a 11 experiment in how to effectively carry a big milk bottle with two 12 hands. Let’s go out in the back yard and fill the bottle with water and see if you can 13 .” The little boy learned that if he 14 the bottle at the top near the lip with both hands, he could carry it without dropping it. What a wonderful 15 !
This scientist then said that it was at that moment that he knew he didn’t need to be 16 to make mistakes. Instead, he learned that mistakes were just 17 for learning something new, which is, 18 , what scientific experiments are all about. Even if the experiment “doesn't 19 ,” we usually learn something 20 from it.

Two men, both seriously ill, were in the same hospital room. One man was allowed to 46 in his bed for an hour each afternoon for treatment. His 47 was next to the room's only window. The other man 48 spend all his time flat on his back. Every 49 when the man in the bed by the window could sit up, he 50 pass the time by describing(描述) to his 51 all the things he could see outside the window. The window overlooked（远眺） a 52 with a lovely lake. Ducks played on the water while children 53 their model boats. Young lovers walked 54 among flowers. As the man by the window described all this beautifully, the other man would close his eyes and 55 the scene.
One morning, the day nurse arrived to bring water for their baths only to find the 56 body of the man by the window, who had died 57 in his sleep. She was sad and 58 the hospital attendants (服务员) to take the body away. 59 it seemed appropriate (合适的), the other man asked if he could 60 next to the window. The nurse was happy to make the switch（调换）, and after 61 he was comfortable, she left him alone. Slowly and painfully, he sat up to take his 62 look at the world outside. Finally, he would have the 63 of seeing it for himself. He strained (紧张地) to slowly turn to 64 the window beside the bed. It faced a blank wall.
The man asked the nurse what could have forced his dead roommate to 65 those wonderful things outside this window. The nurse answered that the man was blind and could not even see the wall. She said, “Perhaps he just wanted to encourage you.”

Have you ever tried to draw a straight line, only to find it turns out all wrong? Or, wanted to show 36 at a party but the song you’d practised so many times suddenly 37 more difficult?
I've had both these 38 .As a Senior 3 student, I have to 39 many exams. Each time I enter one thinking “I 40 fail this time.” , I get a low mark.
But don't be surprised --- it's not 41 we don't try, or do enough preparation, or take it 42 . On the contrary, it is because we put ourselves under too much 43 . It is thinking ‘I must…’ that makes us taste the terrible flavor of 44 .
We often 45 to our friends, “Don't be too hard 46 yourself!”. But when we 47 our own goals, we may not listen to our own advice.
In doing so, we are making our path to success increasingly difficult.
So why not 48 this crazy pursuit(追求) to get the best? Just face the problem 49 before you with a calm mind, enjoy the hard work and you will succeed.
In my opinion, 50 a calm state of mind is a skill for life. For people who want to succeed, 51 this is a very important lesson.
So 52 time when you're trying to draw a straight line or 53 a performance, tell yourself, “If I can just do it better than last time, it's a 54 . ”
Keep a calm state of mind, and you will be happy 55 you succeed or fail.
