7．Public Speaking Training●Get a coach
（16）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．（17）B，so good public speaking training should develop those instead of telling you what you shouldn't do．
●（18）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．
（19）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．（20）A．Your training course should help you bring out your personality，not try to turn you into someone you're not．

A．You aren't like anybody else
B．You already do lots of things well
C．Turn your back on too many rules
D．Check the rules about dos and don'ts
E．Whatever the presentation（呈現(xiàn)），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．

9．Over the last 70 years．researchers have been studying happy and Unhappy people and finally found out ten factors that make a difference．Our feelings of well-being at any moment are determined to a certain degree by genes．However of all the factors，wealth and age are the top two．
Money can buy a degree of happiness．But once you can afford to feed，clothe and house yourself，each extra dollar makes less and less difference．
Researchers find that，on average，wealthier people are happier．But the link between money and happiness is complex．In the past half-century，average income has sharply increased in developed countries，yet happiness levels have remained almost the same．Once your basic needs are met，money only seems to increase happiness if you have more than your friends，neighbors and colleagues．
"Dollars buy Status（社會(huì)地位），and status makes people feel better，"conclude some experts，which helps explain why people who can seek status in other ways-scientists or actors，for example-may happily accept relatively poorly-paid jobs．
In a research，Professor Alex Michalos found that the people whose desires-not just for money，but for friends，family，job，health-rose furthest beyond what they already had，tended to be less happy than those who felt a smaller gap（差距）．Indeed，the size of the gap predicted happiness about five times better than income alone．"The gap measures just blow away the only measures of income，"says Michalos．
Another factor that has to do with happiness is age．Old age may not be so bad．"Given all the problems of aging，how could the elderly be more satisfied？"asks Professor Laura Carstensen．
Why are old people happier？Some scientists suggest older people may expect life to be harder and learn to live with it，or they're more realistic about their goals，only setting ones that they know they can achieve．But Carstensen thinks that with time running out，older people have learned to focus on things that make them happy and let go of those that don't．
"People realize not only what they have，but also that what they have cannot-last forever，"she says．"A goodbye kiss to a husband or wife at the age of 85，for example，may bring far more complex emotional responses than a similar kiss to a boy or girl friend at the age of 20．"

12．According to the passage，the feeling of happinessD．
A．has little to do with wealth
B．increases gradually with age
C．is measured by desires
D．is determined partly by genes
13．Some actors would like to accept poorly-paid jobs because the jobsC．
A．make them feel much better
B．provide chances to make friends
C．improve their social position
D．satisfy their professional interests
14．Aged people are more likely to feel happy because they are moreB．
A．optimistic      B．practical      C．successful     D．emotional
15．Professor Alex Michalos found that people feel less happy ifA．
A．the gap between reality and desire is bigger
B．they have a stronger desire for friendship
C．their income is below their expectation
D．the hope for good health is greater．

6．A simple gesture can be formed into a child's memory so quickly that it will cause the child to give a false answer to a question accompanied by that gesture．A new finding suggests that parents，social workers，psychologists and lawyers should be careful with their hands as well as their words．
While memories of both adults and children are easy to react to suggestion，those of children are known to be particularly influenced，said a researcher，Sara Broaders of Northwestern University．
Previous research，for example，has shown that detailed questions often cause false answers；when asked，say"Did you drink juice at the picnic？"，the child is likely to say"yes"even if no juice had been available．It is not that the child is consciously lying，but rather the detail is quickly formed into his or her memory．
To avoid this problem，social workers have long been advised to ask children only open-ended questions，such as"What did you have at the picnic？"But an open-ended question paired with a gesture，is treated like a detailed question．That is，children become likely to answer falsely．
And 77% of children gave at least one piece of false information when a detail was suggested by an ordinary gesture．Gestures may also become more popular when talking with non-fluent language users，such as little kids．Broaders advises parents and other adults to"try to be aware of your hands when questioning a child about an event．Otherwise，you might be getting answers that don't mean what actually happened．"

32．According to the author，gesturesC．
A．have not any function at all                                      
B．a(chǎn)re rarely used by people
C．have a certain effect on children                               
D．a(chǎn)re often used by social workers
33．In Sara Broaders'view，kids are easy to be misled by gestures just becauseB．
A．these gestures are very attractive                        
B．their memories are affected easily
C．children are easy to tell lies                                      
D．they like these gestures
34．According to the text，which of the following questions may cause a wrong reply？B
A．What will you have for lunch？
B．Did you cheat in the last English examination？
C．Where are you going，Lucy？
D．Did you see anything else last night？
35．When talking with little kids，adults are supposed toD．
A．a(chǎn)sk less open-ended questions                              
B．use familiar words and phrases
C．a(chǎn)sk detailed questions                                         
D．use gestures carefully．
