20.Students usually have two long holidays a year,but have you heard elephants have holidays?
The Indian elephants from a temple are sent on a north-long holiday with massages(按摩) and baths to relax.The 64elephants will be fed with a lot of food,enough for them to put on 700~800pounds.
A temple veterinarian said that those Indian elephants would be treated after spending a month walking on roads,living on leaves and bananas and giving shows during lots of temple festivals.Their daily diet includes special rice and other special food,which are very nutritious and can make them healthy and strong.All of these are made by professional people.
This treatment will also calm them down ahead of a busy work schedule in upcoming events later in the year where they are the main attractions.The special holiday has cost the temple about£12,500,but extra money is ready for being used to treat the animals.
Indians believe that doing something good to elephants can help them get wisdom and power.Having elephants is a traditional symbol of honor for temples across southern India.All temples,however,never buy their elephants.The elephants were donated by people.

17.Think about the last time you felt afraid.Was it a fear of height?Did you oversleep on a weekday and fear you'd get into trouble at the office?In any case,you know what it feels like to feel fear.
But one woman doesn't.The woman,code-named"UM",gave her first-ever interview after years of being studied by a team of researchers.The woman is given a code name because the researchers want to protect her from anyone who would take advantage of her inability to feel afraid.
UM can't tell you what fear is because she's never experienced it."I wonder what it's like to actually be afraid of something,"she said.The formal name for the disease is Urbach-Wieth disease,which is characterized by a hoarse(粗哑的)voice,small bumps around the eyes,and calcium deposits(钙沉积的)in the brain.
In the case of UM,the disease has transformed the part of her brain that controls the human response to fear.In the interview,UM talks about an event in her life where she was held at knifepoint and gunpoint,"I was walking to the store,and I saw a man on a park bench.He said.‘Come here,please,'so I went over to him.He grabbed me by the shirt,put a knife to my throat and told me he was going to cut me.I told him,‘Go ahead and cut me,'I wasn't afraid at a11.And for some reason,he let me go."
Doctors who have been studying UM's condition for years have been trying different things that could strike fear into her.They finally figured something out-increasing UM's carbon dioxide levels.Extra carbon dioxide concentration in the blood is known to cause fear and panic in health individuals.Increasing UM's carbon dioxide levels did manage to give her a fright.

6.The greatest recent social changes have been in the lives of women in America,or probably in the world.
During the twentieth century there has been a remarkable shortening of the proportion of a woman's life spent in caring for the children.A woman marrying at the end of the nineteenth century would probably have been in her middle twenties?And would be likely to have seven or eight children,of whom four or five lived till they were five years old.By the time the youngest was fifteen,the mother would have been in her early fifties and would expect to live a further twenty years,during which custom,opportunity and health made it unusual for her to get paid work.Today women marry younger and have fewer children.Usually a woman's youngest child will be fifteen when she is forty-five years and is likely to take paid work until retirement at sixty.Even while she has the care of children,her work is lightened by modern living conditions.
This important change in women's life-pattern has only recently begun to have its full effect on women's economic position.Even a few years ago most girls left school at the first opportunity,and most of them took a full-time job.However,when they married,they usually left work at once and never returned to it.Today the school leaving age is sixteen,many girls stay at school after that age,and though women tend to marry younger,more married women stay at work at least until shortly before their first child is born.Very many more afterwards return to full-or-part-time work.
Such changes have led to a new relationship in marriage,with the husband accepting a greater share of the duties and satisfactions of family life,and with both husband and wife sharing more equally in providing the money,and running the home,according to the abilities and interests of each of them.
(Note:Answer the questions or complete the statements in NO MORE THAN TEN WORDS.)

78.At what age did most women get married in the late nineteenth century?in their middle twenties.
79.A women today can still take care of her children when doing paid work in their forties because ofher age and the lightened work.
80.Of"such changes"today,one is that many more mothersreturn to full or part-time job after their first child is born.
81.What are the factors that cause a couple to share economic and family affairs in an equal way?Their abilities and interests.
3.We regularly hear how important consumer spending is for the economy.The story goes like this:the more consumers spend,the more money circulates in the economy,which contributes to healthy job growth and profits.Keynes,a British economist,went as far as to say that individuals saving their money may actually be hurting the economy.Sounds troubling,doesn't it?
Fear not.You aren't actually hutting anyone else by saving money.Strong economic growth only comes from one place:savings.Not consumption.In fact,economic activity should not be mistaken for economic growth.For example,somebody takes their money,walks into a store,and purchases goods.The store increases its revenue.
But what happens to all of those goods and services that people have chosen not to consume by saving their money?Simple:Other people are allowed to consume them.Think of it this way:When you lend out your savings,you are actually saying,"Here,I am not going to consume right now,so why don't you?"Banks simply play the middleman:they collect lots of people's savings and then lend out lots of funds.
It takes an unbelievable amount of goods and services to construct a building.It takes food,shelter,and entertainment for all of the workers,as well.Without savings,it is quite impossible to finance such a construction.The coordination(协调)between savings and consumption is a necessary basis for sound economic growth.This coordination is also why consumer lending (say,to borrow a big sum of money to buy a car) is not productive,in a strict sense.It doesn't increase the net (净的) amount of wealth of an economy.Those savings could have been used to construct,say,factory equipment.
None of this means consumption and spending are"bad"things.They simply do not make us wealthier.Alter all,the final goal of production and savings is to consume.But to say that consumption is the engine of economic growth is to put the cart before the horse.Or,to rephrase:the consumption of wealth can never make you wealthier.Happier,perhaps.Wealthier,no.
