1.Most people shake hands and make eye contact when they meet people for the first time.Among very good friends,a woman may give another woman a little hug,and a man may kiss a woman quickly on the cheek.Males don't usually hug one another,however,this is changing.Men usually shake hands with the right hand.Sometimes they use the left hand to either cover the handshake or lightly hold the other person's arm.This shows greater warmth and friendship.Most people wave hello or good-bye by extending the arm,palm facing outward,and twisting the hand at the wrist.Another way is to raise the arm,palm outward,and move the whole arm and hand back and forth.This is important to know because in many other countries,the same movements mean"no".
2.When people are waiting in a public place,such as the post office,they usually form lines.Some people get angry and complain if someone pushes their way into a line or jumps ahead of other people.Moreover,many women like men to open doors for them.They also like men to give up their seats on public transportation.However,some women do not like this type of behavior.They feel that men and women should be treated in the same way.
3.In the United States,it's important to make direct eye contact in business and social situations.If you don't make eye contact,people will probably think that you are bored or not interested.If there is silence in these situations,people usually try to make conversation.Periods of silence make many people uncomfortable.People in the United States usually stand about one arm's length away from each other while talking or standing together.This space is called"the comfort zone".
4.In the United States,mothers sometimes show that they are angry with children by shaking an index finger at them.People may show that they like children by patting them on the top of the head.

People usually make eye contact with each other during________.
A:public transportation
B:the handshake
C:a business meeting
D:line of people
E:her kids

Friendship

Friends play an important part in our lives,and although we may take the fact of
friendship for granted,we often don't clearly understand how we make friends.While we
get on well with a number of people,we are usually friends with only a very few一for
example,the average among students is about 6 per person.
Moreover,a great many relationships come under the blanket term"friendship".In all
cases,two people like each other and enjoy being together,but beyond that,the degree
of intimacy between them and the reasons for their mutual interest vary enormously.
Initially,much depends on how people meet,and on favourable first impressions.As
we get to know people,we take into account things like age,race,physical
attractiveness,economic and social status,and intelligence.Although these factors are
not of prime importance,it is more difficult to relate to people when there is a marked
difference in age and background.
On a more immediate level,we are sensitive to actual behaviour,facial expression,
and tone of voice.Friends will stand closer together and will spend more time looking at
each other than mere acquaintances.Smiles and soft voices also express friendliness,and
it is because they may transmit the wrong signals that shy people often have difficulty in
making friends.A friendly gaze with the wrong facial expression can turn into an aggressive
stare,and nervousness may be misread as hostility.People who do not look one in the eye
are mistrusted when,in fact,they simply lack confidence.
Some relationships thrive on argument and discussion,but it is usual for close friends
to have similar ideas and beliefs,to have attitudes and interests in common一they often talk
about"being on the same wavelength".It generally takes time to reach this point;
sometimes people"click"immediately.The more intimately involved people become, the
more they rely on one another.People want to do friends favours and hate to let them
down.Equally,friends have to learn to make allowances for each other,to put up with
irritating habits,and to tolerate differences of opinion.Imagine going camping with
someone you occasionally meet for a drink!
In contrast with marriage,there are no friendship ceremonies,no rituals to strengthen
the association between two people.But the mutual support and understanding that results
from shared experiences and emotions does seem to create a powerful bond,which can
overcome differences in background,and break down barriers of age,class or race.

Spoilt for Choice

Choice,we are made to believe,is a right. In daily life,people have come to expect endless situations
about which they are required to make decisions one way or another. In the main,these are just annoying
moments at work which demand some extra energy or brainpower,or during lunch breaks like choosing which
type of coffee to order or indeed which coffee shop to go to.But sometimes selecting one option as opposed to
another can have serious or lifelong consequences.More complex decision-making is then either avoided,
postponed,or put into the hands of the army of professionals,lifestyle coaches,lawyers,advisors,and the like,
waiting to lighten the emotional burden for a fee.But for a good many people in the world,in rich and poor
countries,choice is a luxury,not a right. And for those who think they are exercising their right to make
choices,the whole system is merely an illusion,created by companies and advertisers wanting to sell their
wares。
The main impact of endless choice in people's lives is anxiety.Buying something as basic as a coffee pot
is not exactly simple.Easy access to a wide range of consumer goods induces a sense of powerlessness,even
paralysis（瘫痪）,in many people,ending in the shopper giving up and walking away,or just buying an un-
suitable item that is not really wanted in order to solve the problem and reduce the unease.Recent surveys in
the United Kingdom have shown that a sizeable proportion of electrical goods bought per household are not
reilly needed.The advertisers and the manufacturers are,nonetheless,satisfied.
It is not just their availability that is the problem,but the speed with which new versions of products
come on the market.Advances in design and production mean that new items are almost ready by the time
that goods hit the shelves.Products also need to have a short lifespan so that the public can be persuaded to
replace them within a short time.The classic example is computers,which are almost outdated once they are
bought.At first,there were only one or two available from a limited number of manufacturers,but now there
are many companies all with not only their own products but different versions of the same machine.This
makes selection a problem.Gone are the days when one could just walk with ease into a shop and buy one
thing;no choice,no anxiety.
The plethora（过剩）of choice is not limited to consumer items. With the greater mobility of people
around the world,people have more choice about where they want to live and work一a fairly recent phenome-
non.In the past,nations migrated across the earth in search of food,adventure,and more hospitable environ-
ments.Whole nations crossed continents and changed the face of history.So the mobility of people is nothing
new. The creation of nation states and borders effectively slowed this process down.

Why do products have a short lifespan nowadays?
A:They are of poor quality.
B:They are quickly replaced with new ones.
C:They have too many versions.
D:They are not designed by computers.

When students are asked to find out the changes of their hometown and make a plan for anexhibition, which type of the following grouping methods is mostly recommended

A.Whole class work.

B.Group work.
