A pill，code-named HT-0712，may make forgetfulness a thing of the past. It is being developed in the US and could go on sale within five years.

According to the newspaper The Sun，the wonder drug has been nicknamed “Mind Viagra”and has already been shown to boost the memory power of mice and flies. Next it will be tested on humans. This is just one of a number of drugs in a pharmaceutical (制药的) race to develop an increased memory pill. At least 12 US companies are believed to be working on similar projects.

Tim Tully，the founder of US drug company Helicon Therapeutics，who is in charge of the HT-0712 project，gave this practical example of its use for students：“If it takes two weeks to memorize a verse of Shakespeare，with one of these drugs you might be able to do it in two or three days. ”

“The memory drug business appears to be set to become a multi-million dollar industry，”experts say. This summer，100 Americans suffering mild memory loss will test HT-0712 in the first experiment on people.

“You don’t think better than you did before，you just get the facts in with less practice. There is a growing belief that memory and memory loss is just another treatable condition，”says Tully.

However，there is some doubt whether the drugs can really improve memory. In a study by the US’s Yale University Medical School，researchers suggested that the drug might affect other parts of the memory.

A speech is a wonderful opportunity to inform, persuade or entertain. The best speeches often take on a combination of all three of these components（组成部分）. However, before you can go about the writing of a great speech, it is important to set goals. Goals keep you，your speech and your audience focused.
What a goal is
In the context of a speech, a goal is the purpose of the speech, and what it hopes to accomplish. For example, the goal of a eulogy(颂歌) might be to celebrate the life of a loved one. The goal of a speech at a political gathering would be to inform the crowd about the political position of a candidate and persuade them to vote and campaign for the candidate in question（正被讨论的）.
Why a goal is important
Without a goal, a speech is without direction. The goal informs the structure and content of the speech. For example, if a speech's goal is to convince people that smoking is bad for them, the speech will be structured with persuasive arguments to back up the goal. A speech with a goal of informing the audience will keep the information fair and factual.
A goal is incredibly important to the speech's ability to connect with an audience. If the speaker is unaware of the goal of the speech, the audience will likely be unaware as well. This severely reduces the effectiveness of the message.
Aside from informing the audience of the content and structure, a speech's goal drives the speaker to greater heights. If a speaker is asked to speak on a specific subject, but never establishes the goal, they won't know where to start in the research, organizing and writing of the speech.
______________
If you have been charged with(被委以) delivering a speech, establishing a goal can seem difficult at first. There are several things to take into consideration. First, think about who you will be speaking to. The demographic(人口统计) of your audience will likely determine whether you will be able to persuade them, or whether they will be able to sit through（一直坐到……结束）. Second, think about the topic itself. If the topic is something controversial（有争议的）, it may worth your while to consider an informative approach to present both sides of the issue. Finally, consider your resources. A speech with an informative or persuasive goal usually requires a great deal of research, and sometimes takes more time to write.

D．Informing, writing and persuading.

People all over the world today are beginning to hear and learn more and more about the problem of pollution. Pollution is caused either by man's release of completely new and often artificial substances into the environment, or by releasing greatly increased amounts of a natural substance , such as oil tankers into the sea．

The whole industrial process which makes many of the goods and machines we need and use in our daily lives, is bound to create a number of waste products which upset the environmental balance, or the ecological balance as it is also known. Many of these waste products can be prevented or disposed of sensibly, but clearly while more and more new and complex goods are produce there will be new, dangerous wastes to be disposed of, for example, the waste products from nuclear power stations. Many people, therefore, see pollution as only part of a larger and more complex problem, that is, the whole process of industrial production and consumption of goods. Others again see the problem mainly in connection with agriculture, where new methods are helping farmers grow more and more on their land to feed our ever-increasing populations. However, the land itself is gradually becoming worn out as it is being used in some cases, too heavily, and artificial fertilizer cannot restore the balance.

Whatever its underlying reasons, there is no doubt that much of the pollution caused could be controlled if only companies, individuals and governments would make more efforts. In the home there is an obvious need to control litter and waste. Food comes wrapped up three or four times in packages that all have to be disposed of; drinks are increasingly sold in bottles or tins which cannot be reused． This not only causes a litter problem, but also is a great waste of resources, in term of glass, metals and paper. Advertising has helped this process by persuading many of us not only to buy things we neither want nor need, but also to throw away much of what we do buy. Pollution and waste combine to be a problem everyone can help to solve by cutting out unnecessary buying ,excess consumption and careless disposal of the products we use in our daily lives.

45．The underlined phrase “disposed of ”in the second paragraph means_______.

A． dealt with               B． exposed 

C． disapproved of           D． collected

46． In the writer’s view ,the more new goods, _______.

A． the less pollution             

B． the harder pollution can be prevented

C． the more pollution there will be

D． the more easily pollution can be controlled

47．What can we learn from the last paragraph?

A． We can do much to reduce pollution.

B． The government is trying hard to stop pollution.

C． Individuals know how to get rid of the habit of littering everywhere.

D． We can’t stop buying unnecessary things.

48． People can help solve the problem of pollution by _______.

A． urging their governments to control litter and waste

B． making anti-pollution advertisements

C． cutting down the use of oil and other oil products

D． reducing unnecessary buying, over-consumption and careless disposal of wastes

Time spent in a bookshop can be most enjoyable, whether you are a book—lover or merely go there to buy a book as a present. You may even have entered the shop just to find shelter from a sudden shower. Whatever the reason, you can soon become totally unaware of your surroundings.

The desire to pick up a book with an attractive dust jacket is irresistible, although this method of selection ought not to be followed, as you might end up with a rather dull book.

You soon become interested in some book or other, and usually it is only much later that you realize you have spent far too much time there and must dash off to keep some forgotten appointment—without buying a book, of course.

This opportunity to escape the realities of everyday life is, I think, the main attraction of a bookshop. There are not many places where it is possible to do this. A music shop is very much like a bookshop. You can wander round such places to your heart’s content. If it is a good shop, no assistant will approach you with the inevitable greeting:“Can I help you, sir?” You needn’t buy anything you don’t want. In a bookshop an assistant should remain in the background until you have finished browsing. Then, and only then, are his services necessary. Of course, you may want to find out where a particular section is, but when he has led you there, the assistant should retire discreetly(谨慎地) and look as if he is not interested in selling a single book.

You have to be careful not to be attracted by the variety of books in a bookshop. It is very easy to enter the shop looking for a book on, say ancient coins and to come out carrying a copy of the latest best-selling novel and perhaps a book about brass—rubbing—something which had only slightly interested you up till then. This volume on the subject, however, happened to be so well illustrated and the part of the text you read proved so interesting that you just had to buy it. This sort of thing can be very dangerous. Apart from running up a huge account, you can waste a great deal of time wandering from section to section.
