11．There is an English saying，"Laughter is the best medicine．"Until recently，few people took the saying seriously．Now however，doctors have begun to look into laughter and the effects it has on the human body．They have found that laughter really can improve people's health．
Tests were carried out to study the effects of laughter on the body．People watched funny films while doctors checked their heart，blood pressure，breathing and muscles．It was found that laughter has similar effects to physical exercise．It increases blood pressure，makes the heart beat quicker and makes people breathe deeper； it also works several groups of muscles in the face，the stomach，and even the feet．If laughter exercises the body，it must be beneficial．
Other tests have shown that laughter appears to be able to reduce the effect of pain on the body．In one experiment doctors produced pain in groups of students who listened to different radio programmes．The group that tolerated the pain for the longest time was the group which listened to a funny programme．The reason why laughter can reduce pain seems to be that it helps to produce a kind of chemical in the brain which diminishes both stress and pain．
  As a result，some doctors in the United States hold laughter clinics，in which they help to improve their patients'condition by encouraging them to laugh．They have found that even if their patients do not really feel like laughing，making them smile is enough to produce beneficial effects similar to those caused by laughter．
49．The underlined word"diminishes"in the third paragraph means"D"．
A．delays        
B．prevents        
C．increases       
D．reduces
50．Why do doctors hold laughter clinics？C
A．Because they want to ear n more money．
B．Because they think they will help the patients recover from illnesses．
C．Because they want to improve their patients'health．
D．Because they want their patients to laugh more．
51．What would be the best title for this passage？D
A．Both laughter and physical exercise are good for health．
B．Laughter clinics can help patients improve their condition．
C．Laughter can reduce the effect of pain．
D．Laughter is the best medicine．

1．Public Speaking Training
●Get a coach
（36）E，so get help．Since there are about a billion companies out there all ready to offer you public speaking training and courses，here are some things to look for when deciding the training that's right for you．
●Focus on positives
Any training you do to become more effective at public speaking should always focus on the positive aspects of what you already do well．Nothing can hurt confidence more than being told that you aren't doing well．（37）B，so good public speaking training should develop those instead of telling you what you shouldn't do．
●（38）C
If you find a public speaking course that looks as though it's going to give you lots of dos and don'ts，walk away！Your brain is so full of what you're going to be talking about．（39）G．As far as we're concerned，there are basically no hard and fast rules about public speaking．Your audience can be your friends．
●You are a special person not a clone
Most importantly，good public speaking training should treat you as a special one，with your own personal habits．（40）A．Your training course should help you bring out your personality，not try to turn you into someone you're not．

B．You already do lots of things well

E．Whatever the presentation，public speaking is tough
F．The one thing you don't want is for them to fall asleep
G．So trying to force a whole set of rules into it will just make things worse．
2．We appeal to the public to boycott goods of poor quality．
19．The government must find an _________policy to deal with this problem．（　　）

6．Miss White has called several times this morning；Obviously（obvious），there is   something very important．
16．A person，like a commodity （商品），needs packaging．But going too far is absolutely undesirable．A little exaggeration，however，does no harm when it shows the person's unique qualities to their advantages．To show personal attractiveness in a casual and natural way，it is important for one to have a clear knowledge of oneself．A skilled packager knows how to add art to nature without any signs of embellishment（装饰），so that the person so packaged is not a commodity but a human being，lively and lovely．
    A young person，especially a female，shining with beauty and full of life，has all the favor granted by God．Any attempt to make up would be self-defeating．Youth，however，comes and goes in a flash．Packaging for the middle-aged is primarily to hide the marks made by years．If you still enjoy life enough to keep self-confidence and work at pioneering work，you are unique in your natural qualities，and your attractiveness and grace will remain．Elderly people are beautiful if their river of life has been through plains，mountains and jungles，running its course as it should．You have really lived your life，which now arrives at a self-satisfied stage of quietness and calmness with no interest in fame or wealth．There is no need to make use of hair dyeing．The snow-capped mountain is itself a beautiful scene of fairyland．Let your looks change from young to old in step with the natural ageing process so as to keep in harmony （和谐）with nature，for harmony itself is beauty，while the other way round will only end in unpleasantness．To be in the elder's company is like reading a thick book of deluxe（better quality）edition that attracts one so much as to be unwilling to part with．
　　As long as one find where one stands，one knows how to package oneself，just as a commodity sets up its brand by the right packaging．

A．people should be packed at all ages

20．When I was about 12，I had an enemy，a girl who liked to point out my shortcomings（缺点）．Week by week her list grew：I was very thin，I wasn't a good student，I talked too much，I was too poud，and so on．I tried to hear all this as long as I could．At last，I became very angry．I ran to my father with tears in my eyes．
He listened to me quietly，then he asked．"Are the things she says true or not？Janet，didn't you ever wonder what you're really like？Well，you now have that girl's opinion．Go and make a list of everything she said and mark the points that are true．Pay no attention to the other things she said．"
I did as he told me．To my great surprise，I discovered that about half the things were true．Some of them I couldn't change （like being very thin），but a good number I could-and suddenly I wanted to change．For the first time I go to fairly clear picture of myself．
I brought the list back to Daddy．He refused to take it．"That's just for you，"he said．"You know better than anyone else the truth about yourself．But you have to learn to listen，not just close your ears in anger and feeling hurt．When something said about you is true，you'll find it will be of help to you．Our world is full of people who think they know your duty．Don't shut your ears．Listn to them all，but hear the truth and do what you know is the right thing to do．"

C．He told her to write down all that her"enemy"had said about her and pay attention only to the things that were true．
D．He refused to take the list and have a look at it．
26．What does"Week by week her list grew"mean？A
A．Week by week she discovered more shortcomings of mine and pointed them out to me．

D．Week by week，my shortcomings grew more serious．
