Ways to Get Your Kids into Nature
Being in nature for kids has tremendous health benefits. There are many ways you can incorporate nature into your children’s lives, even if you live in the city.
Inspire curiosity by being curious yourself. A parent’s excitement can be spread to the children, and when you show respect for nature, your children follow suit. 1.. “I don’t know! Let’s find out together.” is a wonderful way to get the ball rolling. Be open to a mutual adventure and allow your curious inner child to come out while you explore nature with your children.
2.. If you have to carpool(拼车) in the morning, turn off the devices instead and encourage your children to look out of the window. The early morning fall skies are beautiful with color and migrating birds. After all, even views of nature from the car window are calming and beneficial.
Stop thinking about nature time as leisure time. Time in nature is an essential investment in your children’s health and wellbeing. If you view nature time as essential to good health, you will be more likely to engage in it. 3.， nurturing creativity and wonder is part of your responsibility as parents.
Look at the stars. Visit your local observatory, and then drive out of the city some morning or evening for your own stargazing(天体观察) with a blanket and telescope. Observing the stars offers a deeper and wider understanding of the universe. 4..
Plant a small garden. 5.. Bean and pea plants grow quickly and can be eaten when mature, so teach your children about food and the wonder of growth.

Alibaba Cloud and the Hangzhou city government announced the launch of ET City Brain 2.0, a cloud—powered and Al-driven urban traffic-management system that aims to increase the city’s efficiency.
After over two years of testing in Alibaba’s home base, ET City Brain has become the new infrastructure (基础设施) for Hangzhou, with a total coverage of 420 square kilometers in area, including over 1,300 traffic lights. Over 200 traffic officers are connected via mobile phones, enabling them to receive real-time alerts on any traffic-related emergencies.
In version 2.0, the system will optimize the city’s firefighting abilities by providing key information to firefighters, such as water pressure, the number and position of fire hydrants (消防栓) in a given area, the location of gas pipes and other details they need to know. The information is instant, making the entire firefighting process faster, safer and more accurate.
City Brain gives meaning to data. By using AI and advanced algorithms (计算程序), City Brain is able to analyze a large amount of data and turn them into useful information in real-time speed.
As a result of City Brain’s ability to predict traffic flow, detect accidents and provide instant feedback, Hangzhou has dropped from 5th to the 57th on the list of China’s most congested cities. Hangzhou is probably the only city that can tell you how many cars are on the street at any given time.
In the case of medical emergencies, City Brain is able to change traffic lights, so emergency vehicles like ambulances and fire trucks can head to the scene without interruption, accelerating their arrival time by 49%.
Dr. Wang Jian, the head of Alibaba’s Technology Steering Committee who invented the term “City Brain”, said the system is designed to empower a city to act quickly and directly. It is more than just about traffic management. It’s really about how to make city more livable at a time of shrinking natural resources around the globe. “It is a matter of sustainability, while using as little natural resources as possible,” Wang said, “This is just the beginning.”
1.What benefit will ET City Brain bring?
A.Lower crime rates.
B.Efficient government.
C.Less traffic congestion.
D.Improved medical care.
2.Which of the following functions of the city Brain is NOT mentioned in the text?
A.Predicting traffic flow.
B.Giving quick feedback.
C.Changing traffic lights.
D.Handling traffic accidents.
3.Which of the following best explains “optimize” in paragraph 3?
A.Better. B.Practise.
C.Operate. D.Emphasize.
4.What can we conclude from the last paragraph?
A.ET City Brain 2.0 is a mature version.
B.Alibaba targets environmentally-friendly development.
C.The government is devoted to improving the system.
D.The system can solve the problem of lack of resources.
You try to keep your eyes wide open while watching a basketball match or a wonderful firework show in case you might miss something exciting in just the blink (眨眼睛) of an eye. But in fact, humans blink about 15 times per minute on average. Have you ever missed anything because you blinked? Probably not. Why is that?
According to a new study published in the journal Current Biology in September, our brain has the ability to skip the temporary darkness when we blink. It can keep visual information for a short period of time and then put it together to form an image without interruption.
In order to understand how this works, a group of scientists at the German Primate Center and the University Medical Center Gottingen in Germany conducted an experiment. In the study, the participants were asked to look at patterns on a screen whose direction could be shown in different ways, such as horizontally or vertically (垂直地). When one pattern was about to disappear and the next one was about to come, the participants had to indicate the direction that the next pattern would appear.
The researchers found that when the directions of two patterns didn’t match, the area in our brain which is responsible for visual memory was activated. This same area showed less activity when two patterns were in the same direction.
“The medial prefrontal cortex (前额叶皮层) adjusts current visual information with previously obtained information, and thus enables us to sense the world with more stability, even when we briefly close our eyes to blink，” Caspar Schwiedrzik explained in Science Daily. He is the first author of the study and also a scientist at the German Primate Center.
1.We don’t miss anything when blinking because our brain can ________.
A.remember all that we see B.deal with the missing image
C.imagine what our eyes miss D.recognize our pieces of memory
2.What does the underlined word “it” in Paragraph 2 refer to?
A.Visual information. B.Our brain.
C.Current Biology. D.The temporary darkness.
3.What do we know about the experiment?
A.The different directions activated visual memory.
B.Visual memory can be more activated by similarity.
C.Participants can interpret patterns differently.
D.The two patterns appear at the same time.
4.The passage is mainly talking about ________.
A.the brain’s structure B.the brain’s special skill
C.the brain’s activated patterns D.the brain’s directions
