Nowadays, more and more parents are using a new technology-home security systems, to keep an eye on their “home-alone” children. In the early days of home security, the systems were basically designed just to keep the bad guys out. 1. But be sure, when no adult is present, he or she knows how to do so safely.
Every child should memorize his or her own full name and address, and home, work and cellphone numbers of each parent. 2. If your child is too young to memorize the information, he or she may be too young to be home alone—for any time.
3. If a door or window is slightly open, the child has any reason to suspect someone has been in the house that shouldn’t be, have him or her call you, then wait at the nearby home of a neighbour who’s agreed to act as a safe house.
4. Besides, set a rule that he or she must never play outside the house when no one else is at home.
Be sure your child knows how to disarm (解除) and arm your home security system. Program your control panel (控制板) to give you a message when your child enters or leaves the house, and arms or disarms the system. 5.
If you want to learn more about home security systems that can help parents protect their “home-alone” children, you can visit www.ProtectAmerica.com.
A. Also keep this information posted next to the phone at home.
B. Teach your child to observe things when returning to the house.
C. At present, the systems are only intended for home-alone children.
D. Warn your home-alone child never to answer the doorbell or telephone.
E. You and your child should work together to use the home security systems.
F. Now, many parents are also using them to make their home-alone children safe.
G. If your child forgets to rearm the system, you can call him or her with a personal reminder.
A new study shows students who write notes by hand during lectures perform better on exams than those who use laptops.
Students are increasingly using laptops for notetaking because of speed and legibility (清晰度). But the research has found laptop users are less able to remember and apply the concepts they have been taught.
Researchers performed experiments that aimed to find out whether using a laptop increased the tendency to make notes “mindlessly” by taking down word for word what the professors said.
In the first experiment students were given either a laptop or pen and paper. They listened to the same lectures and were told to use their usual notetaking skills. Thirty minutes after the talk, they were examined on their ability to remember facts and on how well they understood concepts.
The researchers found that laptop users took twice as many notes as those who wrote by hand. However, the typists performed worse at remembering and applying the concepts. Both groups scored similarly when it came to memorizing facts.
The researchers’ report said “While more notes are beneficial, if the notes are taken mindlessly, as is more likely the case on a laptop, the benefit disappears.”
In another experiment aimed at testing long term memory, students took notes as before but were tested a week after the lecture. This time the students who wrote notes by hand performed significantly better on the exam.
These two experiments suggest that handwritten notes are not only better for immediate learning and understanding but that they also lead to superior revision in the future.
1.More and more students favour laptops for notetaking because they can ________.
A.understand lectures better B.digest concepts better
C.get higher scores D.write more notes
2.While taking notes, laptop users tend to be ________.

3.The author of the passage aims to ________.
A.stress the benefit of taking notes by hand B.examine the importance of long term memory
C.explain the process of taking notes D.encourage the use of laptops
4.The passage is likely to appear in ________.
A.a newspaper advertisement B.a computer textbook
C.a science magazine D.a finance report
The endangered pandas in Qinling Mountains might face a new threat: the loss of their food—bamboo, which makes up 99% of their meals.
Adult pandas spend most part of the day eating bamboo and have to take in at least 40 pounds a day to stay healthy. However, a new study published in Nature and Climate Change warned that they may soon find their food gone because most of the bamboo in Qinling Mountains might disappear by the end of the century as a result of rising temperature worldwide.
A team made up of researchers from Michigan State University and the Chinese Academy of Sciences has studied the effects of climate change on the bamboo in Qinling Mountains. They have found that bamboo is very sensitive to climate changes. “80% to 100% of the bamboo would be gone if the average temperature increases 3.5 degrees worldwide by the end of the century.” said Liu Jianguo, one of the report’s authors. He added, “This is how much the temperature would rise by 2100 even if all countries will keep their promises in the Paris Agreement. But you know what is happening around the world.”
In recent years, China has been trying its best to protect the endangered pandas by setting up more and bigger natural reserves.
“But it is far from being enough and the endangered pandas need cooperation from the rest of the world, because their future is not just in the hands of the Chinese,” said Shirley Martin from World Wildlife Fund but not a member of the team.
The Qinling Mountains, in the southwest of China, are home to about 260 pandas. That is about 13% of the Chinas wild panda population. In addition, about 375 are living in research centers and zoos in China.

3.What does Liu Jianguo mean?
A.Bamboo is sensitive to the changes of temperature.
B.China needs more help from World wildlife Fund.
C.China is making great efforts to protect the pandas.
