     Surface Exploration. Robots make great explorers on planets,moons,and other landing areas.
Aside from Earth,just about every surface in the solar system is unsafe for humans to explore.The
air on most other planets is insufficient for humans to breathe,making it necessary to wear a space
suit and oxygen equipment.The temperatures on these surfaces are much too hot or much too cold
for any humans to withstand.Plus there would be complications with radiation,weather,and a lack
of gravity.Robots have much less limitation in these areas and can survive much longer under these
conditions.
     Data Collection. Robots are designed for collecting scientific data.Robots are also able to
perform many tasks at one time and can process information much quicker and more efficiently.
Important scientific projects from detecting minerals,analyzing ground samples,and finding water
are all performed much quicker and more accurately(精确地)by robots.
     Cost Effective. The use of robots has made the cost of space exploration much less expensive
than it would cost for humans to do the work.In order to successfully send humans into space we
would need to build a vehicle that can not only carry humans,but also have enough food and water to
keep them alive for the duration of the trip.Moreover,robots have no problems working for hours on
end.Robots never complain,they don't require food or water,and they never need a bathroom break.
     Space Travel. Over the past 30 years or so there have been many different types of robots used
successfully in the exploration of space.Perhaps the most famous and successful robots are the Spirit
and Opportunity who have both been exploring the surface of Mars.They have both been very
successful with experiments on soil and rocks and have even found evidence of water in Mars' history.
1.According to the passage,which of the following is NOT true?
A.The use of robots in space exploration costs more than the use of humans.
B.It may be dangerous for human to explore the solar system except the earth.
C.Both the Spirit and Opportunity have found the evidence of water in the Mars.
D.Many different types of robots have explored the space successfully.
2.Which column of the passage could come from?
A.Education.  
B.Finance.
C.Travel.  
D.Science.
3.The underlined phrase "withstand" most probably means "________".
A.arise  
B.bear
C.defeat  
D.diverse
4.What is the writer's attitude in writing this passage?
A.Negative.  
B.Persuasive.
C.Subjective. 
D.Objective.

  It was a day to celebrate if your family had put most of its money in a bank.You will get more money back because of a recent rise in interest rates(利率).

  On October 29, for the first time in nine years, the People’s Bank of China(PBOC)raised interest rates.The rate for one-year renminbi deposits(存款)was increased from 1.98 per cent to 2.25 per cent.And the rate for one-year renminbi loans(代款)went up from 5.31 per cent to 5.58 per cent.Longer term rates saw higher increases.

  So what are interest rates?Banks offer some money to encourage people to keep their savings in a savings account(储蓄帐户),and ask more money in return if you borrow money from them.The percentages of the extra money are the interest rates.

If your parents have borrowed money from banks to pay for houses or cars, the interest rates rise was not good news.

  An increase in the interest rates on a loan means the borrower will need to repay more to the bank.For example, a person who borrowed, 10,000 yuan from the bank had to return 10,531 yuan before the interest rise.But after the interest rates are increased, he has to pay extra 27 yuan per year.

  The rise came following a great demand for the cooling of the over-heating Chinese economy.For several years, pushed by a huge investment and construction projects, the country has had the fastest economic growth in the world.But this can be damaging just as it is when a person grows too fast and can no longer fit their clothes.It is hoped that with a higher interest rate people will act more cautiously and take less risks when borrowing money.

  “The rate rise will help the economy to cool down.It will reduce investment in unnecessary industrial and construction projects.”said Su Ning, deputy governor(副行长)of the PBOC.

(1)

If we deposit 1000 RMB in the bank for one year, how much can we get after October 29?

(The tax rate on interest rates is 20%.)

[  ]

A.

21.6.

B.

13.68.

C.

15.84.

D.

18.

(2)

What is the purpose of the rise in the interest rates?

[  ]

A.

To attract greater investment.

B.

To make people earn more money.

C.

To carry out construction projects.

D.

To cool down the over-heating Chinese economy.

(3)

By saying “this can be damaging just as it is when a person grows too fast and can no longer fit their clothes” the writer ________.

[  ]

A.

warns that if the economy grows too rapidly, it will cause trouble

B.

warns us that industry will suffer a loss

C.

advises us to buy bigger clothes when we are young

D.

advises us not to grow too fast

(4)

Which of the following is NOT a result of the increase in the interest rates on a loan?

[  ]

A.

People will make wiser investments.

B.

People will need to repay more to the bank.

C.

People will borrow more money to invest in their business.

D.

People will be careful of taking money from banks to expand their business.

against attack. Ask for a recommendation from a bike shop.

your bicycle. It should be clearly written and include your postcode and your house or flat
number. This will provide a simple way to identify your bicycle.

then put your registration number and personal details on their computer database. Then if
your bicycle is found it will be easy to contact you.
     Finally
     Keep a record of the bicycle yourself: its make, model and registration number. You can
even take a photograph of it. This will prove the bicycle belongs to you.
