The human brain contains 10 thousand million cells（細胞）and each of these may have a thousand connections.Such great numbers used to discourage us and cause us to stop thinking about the possibility of making a machine with humanlike ability，but now that we have grown used to moving forward at such a speed，we can be less sure.Quite soon，in only 10 or 20 years，perhaps，we will be able to build a machine as complex（復雜的） as the human brain，and if we can，we will.It may then take us a long time to make it as intelligent as the human brain by properly programming it.
I think it is certain that in decades，not centuries，machines of silicon（硅）will arise to compete with their human ancestors.In a real sense they will be able to reproduce themselves.Silicon will have ended carbon's long control.And we will no longer be able to consider ourselves to be the finest intelligence in the world.
As the intelligence of robots increases and their cost goes down，we may achieve a lot with their help，first on the earth through their ability to complete any kind of work in harmful environments.In the end，deserts（沙漠）may turn into gardens.Further ahead，by a combination of the great wealth this new age will bring and the technology it will provide，the creation of a huge，man-made world in space，home to thousands or millions of people，will be within our power.

A

.
A．is complex and intelligent
B．is too complex to be reproduced

（2）The underlined word "carbon" in Paragraph 2 stands for

   Find out what activities are available（可用的）and look into each one .（4）

If the website seems incomplete，talk with your teacher or parents.Also look for calendar details，such as start-and-end dates，plus event schedules，to make sure it won't get in the way of anything else going on in your life.Once you have a list of activities that match your interests，do a little research. （5）

2．When it comes to making healthy lifestyle changes，which should come first-changing your diet or becoming more physically active？
   Previous studies suggested that providing people with too much information about nutrition and physical activity at once tends to be discouraging.That has led to the popularity of advising people to make changes gradually，and set smaller goals.
   So the scientists divided 200 inactive participants who were age 45 or older into four groups.One group was instructed about making diet and fitness changes at the same time，the second group was taught about diet changes first，then fitness changes four months later，the third group changed their exercise habits first and made changes in their eating habits four months later，and the final，control group was not instructed about either diet or fitness changes but about how to manage their stress.
   The researchers tracked the groups for a full year.Compared to the control group，the three intervention（干預）groups made healthy changes in their diet.Those who changed their fitness habits first significantly increased the amount of exercise they received daily compared to the other groups after four months.However，at the end of the year，the group that changed both diet and exercise at the same time was the only one that met the nationally recommended targets for both exercise and nutrition levels，while those who worked on improving their nutrition first were unable to meet the recommended levels of fitness after a year.The researchers suspect that changes to diet are easier to make than changes to physical activity.
   The findings show，however，that pairing diet and exercise changes may help to overcome some of the barriers people face in adding more physical activity into their lives.If folks change diet and exercise orderly，the scientists say，they may end up placing more importance on the first set of behavior changes and feel less pressured to address the second set.

（1）The advice mentioned in the second paragraph seemed

.
A．popular
B．dangerous
C．scientific
D．unsatisfactory
（2）Which group made progress earlier than other groups in increasing the amount of daily exercise？

A．The first group.
B．The second group.
C．The third group.
D．The control group.
（3）The reason why those improving their nutrition first failed to meet the levels of fitness after a year might be that

.
A．they might be very lazy
B．they wouldn't like to change their behavior
C．it is much harder to change physical activity
D．they might put on weight before changing their physical activity
（4）Which of the following does the author probably approve of？

A．Pairing diet and exercise changes.
B．Becoming more physically active first.
C．Changing diet and exercise following a fixed order.
D．Changing diet first and placing more importance on it.

3．Shawn Seipler is on the way to saving lives with soap.It began about seven years ago as a tiny business with a few friends and family in a single car garage in Florida，where they recycled used soap into fresh bars.The organization，now called Clean the World，has grown to include cities where hotels are plentiful and used bars of soap can be gathered easily.
   As a frequent traveler while working for a tech company，Seiler had a sudden thought one night at a hotel."I picked up the phone and called the front desk and asked them what happened to the bar of soap when I was done using it." he recalled.Learning that they would go to the dustbin，he began his task to help save lives with soap and even half-used bottles of shampoo.It's a huge problem.One of the most common kinds of illnesses in the world are those that are passed from person to person and to oneself because of dirty things that are on one's hands.
   In the U.S.and other developed nations，hygiene（衛(wèi)生）products are everywhere.Not so in some other countries，where Seipler recalled visiting a hospital once in the Middle East to find that soap was in such short supply that patients had to provide their own. "It's such an important part of the interruption of infectious germs that could save so many lives，" he said.
   Clean the World now collects used soap from more than 4，000 hotels and has delivered 25 million bars to 99 countries.The process is fairly simple with the collected soap being cut into pieces and then run through machines that remove any remaining bacteria before being pressed into new bars of soap and packaged for delivery.

（1）Shawn Seipler got the idea of collecting seconding soap

.
A．by chance
B．from the front desk
C．after calling his friend
D．after visiting the Middle East
（2）How do hotels deal with used soap traditionally？

A．They sell it.
B．They save it.
C．They drop it.
D．They recycle it.
（3）What can be learned from Paragraph 3？

A．Soap isn't fully appreciated.
B．Soap can prevent many illnesses.
C．Soap is needed in developed countries.
D．Soap means little to developing countries.
（4）Which of the following can best describe Shawn Seiler？

A．Determined and optimistic.
B．Friendly and open-minded.
C．Warm-hearted and creative.
D．Hard-working and ambitious.
