Ⅰ.阅读理解

Every November,Time magazine picks out what
it calls“The 25 Best Inventions”of the year. Here,
Teens has chosen some of the most interesting ones.
Ember Mug
Its hard to always keep coffee at the right
temperature,especially in winter. Its too hot to drink
at first,but before we know it,it gets too cold and
loses all its taste. The perfect level of warmth for a
cup of coffee only lasts for 37 seconds,which makes
the Ember Mug a great innovation. It keeps your
coffee or tea at a certain temperature, anywhere
between 45 ℃ and 62 ℃ once you set it through a
smartphone app.
Tasty One Top
TV cooking shows make cooking look so easy,
but its almost impossible to get the recipes t
o cook the
—561—
same as how the professionals cook. However,the
Tasty One Top DIY cooking companion is here to
help. Developed by Buzzfeed, the cooker can be
connected to a smartphone app,which has more than
1,700 recipes and videos. You choose a recipe and
the app will let you know what to do. For example,
itll tell you when to turn your steak or when to add
certain ingredients.
Jibo
Smart speakers from companies like Amazon and
Xiaomi have added a lot of fun to our lives,but
theyre still just faceless speakers. However,Jibo,
developed by MIT professor Cynthia Breazeal,has
brought smart technology to life. Said to be“the
worlds first social robot for the home”,Jibo looks like
a cartoon character. Inside its“head”,there are
various sensors(传感器)and cameras,which allow it
to recognize faces and speech. It can also set alarms,
remind you of important things,tell you the weather
and read news or messages from your friends and
family.

Modern day robots may not be as entertaining as
R2D2 or the robot from Lost in Space,but robots are
very important to space exploration and are being used
in a variety of different ways for several important
reasons.
Robots make great explorers on planets,moons,
and other landing areas. Aside from the 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.
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,to finding water
are all performed much quicker and accurately by
robots.
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 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 dont
require food or water,and they never need a bathroom
break.
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 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.
—661—
5. Which of the following would be the best title for
the passage?
A. The Development of Robots
B. The Discovery of Space Exploration
C. No Robots,No Space Exploration
D. Robots Are Used in Space Exploration
6. 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 is dangerous for humans to explore other
surfaces in the solar system except the earth.
C. Both Spirit and Opportunity have found the
evidence of water on Mars.
D. Many different types of robots have explored the
space successfully.
7. The underlined word “withstand”in Paragraph 2
most probably means “ ”.
A. remain B. bear
C. defeat D. develop
8. What is the writers attitude in this passage?
A. Negative. B. Persuasive.
C. Subjective. D. Objective.
Ⅱ.七选五
根据短文内容,从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。
The Internet,social media and smart phones allow you to learn many things. 1. However,just like
in the real world,not everyone online is your friend. Some may use these tools to send unpleasant messages to
you,and some may use your information to do something bad. Its very important to know how to stay safe and
have positive experiences online. Here are some tips for you.
Be careful about friend or follower requests. When you have a friend or follower request,check the
persons information first. 2. Only accept friend or follower requests from people you have met in the real
world. Dont chat with people you dont know or trust. This is a good way to keep you safe.
Review location services on your phone and other mobile devices. 3. They may put you in danger
because others can find you easily. To make sure of your safety,turn off the “location services”or “location
settings”features on your mobile devices. Also turn off GPS for the camera,chat and other social media apps.
4. Strong passwords should have some upper and lowercase letters,numbers and symbols. If you
have a strong password,itll be difficult for others to know it. Also,avoid having the same password for all your
social and education accounts. It is really not safe for your accounts.
5. If someone sends unpleasant messages to you online,find someone you feel safe talking to. For
example,you can talk to a parent,a teacher or a trusted adult and ask him to help report and block (屏蔽)
the person. Dont try to do the same thing when others do something that hurts your feelings online.
A. Create strong passwords.
B. Try to get help when necessary.
C. Find out if he or she is someone you know.
D. Friend requests can tell a lot of information.
E. Talk to someone you find safe to talk to online.
F. They also allow you to talk with friends online.
G. Location services can tell others where you are.

1953,leaving many remarkable works. In Xu Beihong Memorial Hall,

you a better understanding of his life and artistic idea.
