任务型阅读(共10小题,每小题1分,共10分)

请认真阅读下列短文,并根据所读内容在文章后表格中的空格里填入最恰当的词(每空1词)。

I used to be the messiest person alive.Over the years, through watching others and by trial and error, I have finally found ways to come up with plans, organize them and follow through with them.

Make an outline of everything you need to have and do to make your plan happen.Make a list of all of the steps that need to be accomplished and think about what needs to be done.

Detail everything thoroughly and read over it so you can start coming up with some mental solutions of how to carry out your plans.

You should ensure that if for some reason way one doesn’t work, you have way two and way three to lean back on.Therefore, different ways are needed at hand.It’s just a matter of being organized.Chances are that there is always more than one way of doing things, and chances are that if one of those ways doesn’t work, one of the other ones will.

Committing yourself to finishing at least part if not all of your plan at once is also necessary.It will show that you not only have initiative to get things rolling, but that you are interested in the results obtained with making the move to get everything done.

If you make a commitment to finish before a specific time, make sure that you carry that out, and be sure to do everything in the way you said you would, within the time-frame you set for yourself.

Don’t try to tackle more things all at a time.All that does can delay your progress, distract you and make you lose your interest, motivation and energy.

Carrying out an effective plan requires being as organized as possible.You will only achieve this by sticking to the order of the plan and not deviating or trying to do more at a time.

Last but not least, you should never abandon things mid-project.It will only annoy everyone around you including yourself.Unfinished plans are a waste of time, energy and, in some cases, even money.

So, don’t be afraid of organization.The older we get, the more necessary it becomes to have the skills to follow through with confidence and to be able to carry through plans in an organized and manageable way.It pays to be organized, after all.

Medical scientists are already putting computer chips(芯片)directly into the brain to help people who have Parkinson’s disease, but in what other ways might computer technology be able to help us? Ray Kurzweil is the author of the successful book The Age Of Intelligent Machines. He is also one of the world’s best computer research scientists. He is researching the possibilities.

Kurzweil gets computers to recognize voices. An example of this is Ramona, the virtual hostess of Kurzweil’s website, created by the computer, who is able to understand what you say. Visitors to the website can have their own conversations with her. Ramona also dances and sings.

Kurzweil uses this technology to help people with physical problems. One of his ideas is a “seeing machine”. This will be “like a friend that could describe what is going on around,” he explains. Blind people will use a sensor(传感器)which will probably be built into a pair of sunglasses. This machine will describe to the person everything it sees.

Another idea, which is likely to help deaf people, is the “listening machine”. This invention will recognize millions of words and understand any speaker. The listening machine will also be able to translate what it hears into other languages, so even people without hearing problems are likely to be interested in using it.

But it is not just about helping people with physical problems. Looking further into future, Kurzweil sees a time when we will be able to store what we hear, see and think in a computer. This technology probably won’t be ready for at least 50 years, but when it arrives, it means our minds will be able to live forever.

1.Ray Kurzweil is .

A. a famous medical scientist

B. a computer research scientist

C. a patient with Parkinson’s

D. an inventor of computer chips

2. What can Ramona do?

A. She can talk with her visitors.

B. She can treat brain diseases.

3. How can the “seeing machine” help blind people?

A. It can help to treat their eyes.

B. It can translate into other languages.

C. It can help them to see the future.

D. It can describe to them what it sees.

4. The word “virtual” in Paragraph 2 probably means .

A. 虚拟的 B. 友好的 C. 漂亮的 D. 忙碌的

5.What can be the best title for the text?

A. The Seeing Machines

B. The Listening Machines
