Storage, or warehousing, is a necessary function because production and consumption of goods rarely match: items generally are not sold as quickly as they are made.Inventories build up,both in warehouses and at retail establishments, before the foods are sold.The transporta-tion function is involved in bringing goods to a warehouse and taking them from it to retail stores.
Storage performs the service of stabilizing market price.If, for example, no agricultural product could be stored, all food would have to be put on the market immediately.This would, of course, create a glut and lower prices drastically.There would be an immediate benefit to consumers, but in the long run they would suffer.Farmers, because of low prices, would be forced off the land, and the amount of food produced would decrease.This, in turn, would raise consumer prices.
Warehouses for storage are of several types.Private warehouses are owned by manufactur-ers.Public warehouses, in spite of their name, are privately owned facilities, but they are in-dependent of manufacturer ownership.General-merchandise warehouses store a great variety of products.Cold-storage warehouses store perishable goods, especially food products.Grain ele-vators are a kind of warehouse used to keep wheat and other grains from spoiling.A bonded warehouse is one that stores foods, frequently imported, on which taxes must be paid before theyare sold.Cigarettes and alcoholic beverages are common examples.
The distribution center is a more recently developed kind of warehouse.Many large com- panics have several manufacturing plants, sometimes located outside the country.Each plant doesnot make every company product but specializes in one or more of them.The distribution center allows a manufacturer to bring together all product lines in one place.Its purpose is to minimize storage and to ease the flow of goods from manufacturers to retailers rather than build up extensive inventories.It reduces costs by speeding up product turnover.Very large corporations will have several distribution centers regionally or internationally based

same amount of time, say exercise researchers in Britain. But walks of any length beat sitting at home with your feet up and watching television. They stress. Some researchers in Britain reached these conclusions after putting 56 couch potatoes through an 18 week course of daily walks. They found that longer walks produce the most beneficial changes to the composition of blood fats, but walks of any length improve the fitness of the heart.
In the study, the normally inactive subjects were divided into three roughly equal groups. The "long walker" took a hike of between 20 and 40 minutes every day. "Intermediate walkers" had two rounds of jogging of 10 to 15 minutes, and "short walkers" did three stints of 90 to 110 minutes. The controls sat at home, as usual.
At the start and end of the 18 weeks, the health and fitness of each group were measured and it was found that the long walkers were healthiest, as measured by altered fat profiles in their blood. At the end, each liter of blood from the long walkers contained an average 0.05 grains less apolipoprotein(阿朴脂蛋白) II, a "bad" fat that is linked with heart disease. This was more than twice the drop seen in the intermediate walkers, and five times that in short walkers. In the controls, the level of this fat stayed the same. The drop in apolipoprotein II in the long walker was matched by a rise in the blood level of apolipoprotein I, a "good" fat that is associated with smooth arteries.
1、According to the researchers, ______ is least beneficial to your health.
A、taking a lengthy hike once a day
B、going shopping several times every day
C、doing jogging every morning
D、sitting in the sofa watching TV every evening

B、The subjects in the study all often watch TV
C、Only longer walks benefit our health
D、The subjects in the study may not like exercises
4、The subjects are divided into ______ groups.
A、four
B、three
C、two
D、one
5、Why is long walk beneficial to our heart？()
A、It leads to the drop in apolipoprotein I
B、It leads to the drop in apolipoprotein II
C、It keeps us from watching TV
D、It helps us lose weight
tead of doing your work, you check Facebook or do some on line shopping.This is called procrastination, and it affects everyone.So how can you stop procrastinating？
We often procrastinate because a task seems too big, or impossible to achieve.Try breaking down the task into smaller pieces.For example, instead of thinking，“I need to finish this essay by 10 p.m.tonight ” tell yourself,“I’ m going to make a short outline, fill that in, and then look for quotes.”
Another important factor is your environment, isn’t it？ If there are too many distractions in your work space, you may be tempted to procrastinate more.Are there any things in your work space (for example, a TV) that could be causing you to lose focus？
Making a timeline with goals and deadlines is a great way to stop yourself from procrastinating.
However, it is important to make your deadlines realistic so that you can be sure you’ll stick to them.
Some people like to wait for the perfect time to start a task, while the perfect time is often now.Try something called the Two-Minute Rule to help you get started.This idea comes from David Allen’ s best-selling book, Getting Things Done.It states that.if something takes less than two minutes， such as washing your dishes after a meal, then you should do it now.
1.Procrastination means().
A.putting your work off till later
B.doing your work quickly
C.doing your work carefully
D.doing your work well
2.Sometimes we procrastinate because a task seems too().

B.small
C.fun
D.big
3.Having a TV in your work space is an example of an environmental().
A.distraction
B.reaction
C.attration
D.concentration
4.Setting realistic is a() good way to stop procrastinating.
A.environments
B.deadlines
C.focus
D.places
5.The Two-Minute Rule states that if something takes no more than two minutes, you should().
A.put it aside

听力原文： Some banks offer other types of loans repayable by monthly installments, such as business development loans, house improvement loans, and farm development loans. These may be either secured or unsecured. Secured loans attract a slightly lower rate of interest than unsecured loans. Some banks offer revolving credit schemes. These normally involve loans repayable by regular monthly installments, but they differ from other loans repayable by installments in two respects. First, the borrower need not take up the full amount of the loan at the outset. Secondly, as his repayments reduce his indebtedness, he can "top up" his loan by borrowing more, provided that the total debt outstanding does not exceed his agreed credit limit. In 1967 some banks introduced a new form. of account called a "budget account". The object is to allow personal customers to spread the incidence of normal personal and household expenditure.

25.Which of the following loans would attract a lower rate of interest？
26.How does a borrower "top up" his loan？

(24)
A．Business development loans.
B．House improvement loans.
C．Farm development loans.
D．Overdrafts.
Many people like to think of our present system of schooling as providing plenty of steps up the ladder of success for clever children.It would be good to think that no one who is really bright can be missed out when the state system is apparently so thorough.It is obvious, for instance, that many children from less rich homes reach university or do well in other ways.
Unfortunately, we now have plenty of evidence that many children of every level of ability do much less well than they could.For instance, during the years of national military service it was possible to test the intelligence of all male 18-20 year olds.Half of those soldiers who were placed in the two highest ability groups had left schools at 15.
It has also been shown that the percentage of working class children going to university is almost the same now as it was in 1939.One study of 5000 children from birth to 21 years old indicated that up to half the bright pupils from working class homes left school when they reached 16 years old.Moreover, there is no difference in intelligence between the sexes, but far more boys than girls stay in education after 16.
It is clear from this and much other evidence that many children are still leaving school too early to benefit from the prizes------money, social respectability, and interesting jobs, which higher education gives.It is clear too that the reasons why such children leave have much to do with their social circumstances.Their parents often need the extra money another wage-owner can bring in; they do not value education for itself because their own was probably dull and unhappy.It is not so much that they force their sons and daughters to leave school, rather that they tend to say, “It's up to you”.
1.It is hoped that ROSLA will give all children （）.
A.a more enjoyable time at school
B.the same chances in society
C.the right to a better school
D.higher scored in intelligence tests
2.People would like to think that （）.
A.equal numbers of poor and rich children reach university
B.those with the least money get the best education

A.many of the clever ones leave school early
B.fewer go to university than ever before
C.more than half leave school when they are 16
D.fewer boys than girls stay at school after 16

D.has greatly improved our society
Alzheimer’s Disease: Are We Close to Finding a Cure？
First described in 1906 by Dr.Alois Alzheimer, Alzheimer s disease is the most common form. of dementia, accounting for around 60%–80% of cases.It is characterized by problems with memory, thinking and behavior.Onset is most common in individuals aged 65 and over, although people in their 40s and 50s can develop what is classed as early - onset Alzheimer’s.
Alzheimer’s is a progressive disease, meaning memory loss is mild in the beginning, but it worsens over time to the extent that individuals are unable to have conversations or respond to their surroundings.There are treatments that have been approved by the US
Food and Drug Administration (FDA) for Alzheimer’s.For example, cholinesterase inhibitors and memantine can help treat memory and thinking problems.But these drugs just help manage the symptoms; there is currently no cure for the disease.
Current Alzheimer’s prevalence in the US makes it the 6th leading cause of death, killing more than half a million seniors every year.To put this in perspective, Alzheimer’s disease currently kills more people each year than prostate cancer and breast cancer combined.There is no doubt that scientists across the world are working hard to find ways to prevent, treat and cure this debilitating condition.Hardly a day goes by without coming across a report about how scientists restored memory and learning deficits in Alzheimer’s mouse models, how vitamin D deficiency could increase the risk of developing dementia, and how DNA methylation in the brain is linked to Alzheimer’s.But what have these studies taught researchers about Alzheimer’s so far？
Preventing and Targeting Plaques and Tangles
As with all diseases, knowing exactly what causes Alzheimer’s is key to identifying ways to prevent and treat the condition.Past research has indicated that Alzheimer’s occurs when two abnormal brain structures — plaques and tangles —damage and kill nerve cells, causing the memory, thinking and behavioral problems associated wit
1.Dementia is not a single disease in itself, but a general term to describe symptoms of impairment in memory, communication, and thinking.()
2.The FDA - approved drugs, like cholinesterase inhibitors and memantine, can cure Alzheimer’s disease.()
3.chronic sleep deprivation may cause these abnormal brain structures.()
4.Tangles are fragments of a protein called beta - amyloid, which build up in areas between nerve cells.()
5.As a result of Alzheimer’s research, there are an array of drugs in development that scientists believe have great potential to effectively treat the disease.()
