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.

1.Which of the following can be most likely to replace the underlined word “boost” in the second paragraph?

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.
【小题1】According to the passage, what three components does the best speech combine?

“What is the most important thing you’ve done in your life?” The question was put to me during a presentation I gave to a group of lawyers.
The answer came to me in an instant. It’s not the one I gave, because the situation was not right. As a lawyer in the entertainment industry, I knew the audience wanted to hear some amusing stories about my work with well-known people, but here’s the true answer:
The most important thing I’ve ever done occurred on October 8,1990. I began the day playing tennis with an old friend I hadn’t seen for a while. Between points we talked about what had been happening in each other’s lives. He and his wife had just had a baby boy, who was keeping them up at night.
While we were playing, a car came screaming up the road toward the courts. It was my friend’s father, who shouted to my friend that his baby had stopped breathing and was being rushed to the hospital. In a flash my friend was in the car and gone, disappearing in a cloud of dust.
For a moment I just stood there, paralyzed(呆若木鸡). Then I tried to figure out what I should do. Follow my friend to the hospital? There was nothing I could accomplish there, I convinced myself. My friend’s son was in the care of doctors and nurses, and nothing I could do or say would affect the outcome. Be there for moral support? Well, maybe. But my friend and his wife both had large families, and I knew they’d be surrounded by relatives who would provide more than enough comfort and support, whatever happened. All I could do at the hospital, I decided, was to get in the way. Also, I had planned a full day with my family, who were waiting for me to get home. So I decided to head back to my house and check in my friend later.
As I started my car, I realized that my friend had left his truck and keys at the courts. I now faced another problem. I couldn’t leave the keys in the truck. So I decided to go to the hospital and give him the keys.
When I arrived, I was directed to a room where my friend and his wife were waiting. As I had thought, the room was filled with family members silently watching my friend comfort his wife. I went in and stood by the door, trying to decide what to do next. Soon a doctor appeared. He approached my friend and his wife, and in a quiet voice told them that their son had died.
For a long time the two held each other and cried, unaware of the rest of us standing around in pained silence. After they had calmed themselves, the doctor suggested they spend a few moments with their son.
My friend and his wife stood up and walked past their families. When they reached the door, my friend saw me standing in the corner. He came over and hugged me and started to cry. My friend’s wife hugged me, too, and said , “Thanks for being here.”
For the rest of that morning, I sat in the emergency room of that hospital and watched my friend and his wife hold the body of their infant son, and say goodbye.
It’s the most important thing I have ever done. The experience taught me two lessons.
First: The most important thing I’ve ever done happened when I was completely helpless. None of the things I had learned in university, in three years of law school or in six years of legal practice were of any use in that situation. Something terrible was happening to people I cared about, and I was powerless to change the outcome. All I could do was standing by and watching it happen. And yet it was critical that I do just that--- just be there when someone needed me.
Second: The most important thing I’ve done almost didn’t happen because of things I had learned in classroom and professional life. Law school taught me how to take a set of facts, break them down and organized them. These skills are critical for lawyers. When people come to us for help, they’re often stressed out and depend on a lawyer to think logically. But while learning to think, I almost forget how to feel. Today I have no doubt that I should have leapt into my car without hesitation and followed my friend to the hospital.
From that one experience I learned that the most important thing in life isn’t the money you make, the status you attain or the honors you achieve. The most important thing in life is the kids’ team you coach or the poem you write----or the time when you’re just somebody’s friend.
【小题1】 When he was asked about the most important thing he had done in life at a presentation, the author _______.

It is hard to predict（预言）how science is going to turn out, and whether it is really good science, it is impossible to predict．If the things to be found are actually new, they must be unknown in advance．You cannot make choices on this matter．You either have science or you don’t and if you have it you have to accept the surprising and disturbing pieces of information, along with the neat and useful bits．
The only solid piece of scientific truth about which I feel totally confident is that we don’t know enough about nature．Indeed, I regard this as the major discovery of the past hundred years of biology．It is, in its way, a clear piece of news．It would have amazed the brightest minds of the 18th century to be told by any of us how little we know and how strange the way ahead seems．In earlier times, they either pretended to understand how things worked or simply made up stories to give answers．Now that we have begun exploring seriously, we are catching sight of how huge the questions are, and how far from being answered．Because of this, we are sorry．It is not so bad being ignorant（无知的）if you are totally ignorant; the hard thing is knowing in some details the reality of ignorance, the worst spots and here and there the not so bad spots, but no true light at the end of the tunnel nor even any tunnels that can yet be trusted．
But we are making a beginning, and there ought to be some satisfaction．There are probably no questions we can think up that can’t be answered, sooner or later．Within our limits, we should be able to work our way through to all our answers, if we keep at it long enough, and pay attention．

If you feel at present that you don’t have enough friends in your life, one reason may be that you have let yourself become too busy to make time for the relationships you already have. Starting and keeping friendship requires effort and commitment.
Many of us let our lives become so busy with work and other commitments that we don’t get around to scheduling time for pleasure and renewal（叙旧）with the friends, relatives and acquaintances we already have.
Making the effort to call your friends more regularly and to accept more of the invitations you receive from others can improve your social life in a hurry!
Are there any people you could call right now and be assured of a pleasant welcome? Are there people that you could count on to help you in time of difficulty? Can you have close talks with them? Do you have fun when you are together? Are you happy to have them in your life?
If you haven’t seen much of them lately， is it because you have become too busy? Have you grown apart? Was there an argument?
If the main reason you haven’t been getting together with the people you already know is that you have gotten too busy, take a good look at how you spend your time. Compare it with your real values and priorities（优先考虑的事）in life. Is your busy lifestyle really bringing you the quality of life that you want?
If you have become too busy for friends, why has this happened? Are you seeking material toys in your life at the expense of relationships with other human beings? Have you allowed your time to be over-committed because you never say “No” to anyone? Do you insist on doing things yourself that could be delegated to others? If so, why? Do you believe that everything depends on you?
Examine whether the way you are now spending your time accurately reflects your deepest values and priorities. Make sure that you schedule adequate time for the things that are truly most important to you.
If you really want to keep friends in your life, make a space in your schedule, and a space in your heart for them.
