Your children are watching you. 1. According to the Health Program，developing healthy habits is an important part for your children. And when it comes to developing healthy habits, parents influence their children more than anyone else.
2. What happens during those early years can influence children for the rest of their lives. This includes some eating and exercise habits. Children are very careful, even at a young age. Children watch what others do carefully and imitate the behaviors of those closest to them. As parents, you should do the following: 3. If you do that, your children are more likely to be enthusiastic about developing theirs.
Let your children see you taking care of your own physical health by eating fruits and vegetables. Talk to them about healthy habits in appropriate terms and at a proper time. 4.
5. Computers，televisions and other forms of technology are a major part of life in the 21st century. Unfortunately, as the use of technology in the home increases, so docs the time spent watching TV or playing on the computer. So as parents, you should also arrange the time for your children wisely.

B. Don’t get rid of technology, but use it wisely.
C. Be enthusiastic about developing healthy habits of your own.
D. Your actions arc speaking to them louder than your words will.
F. Children prefer to imitate their parents rather than listen to them.

Self-driving vehicles(车辆) will rely on cameras, sensors and artificial intelligence (人工智能) to recognize and respond to road and traffic conditions, but sensing is the most effective for objects and movement in the neighborhood of the vehicle. Not everything important in a car’s environment will be caught by the vehicle’s camera. Another vehicle approaching at high speed on a collision (碰撞) track might not be visible until it’s too late. This is why vehicle-to-vehicle communication is undergoing rapid development. Our research shows that cars will need to be able to chat and cooperate on the road, although the technical challenges are still great.
The usages of vehicle-to-vehicle communication contain vehicles driving together in a row, as well as safety messages about nearby emergency vehicles. Vehicles could alert each other to avoid collisions or share notices about passers-by and bicycles. From as far as several hundred metres away, vehicles could exchange messages with one another or receive information from roadside units(RSUs) about nearby incidents or dangerous road conditions through 4G network. A high level of AI seems required for such vehicles, not only to self-drive from A to B, but also to react intelligently to messages received. Vehicles will need to plan, reason, strategize and adapt according to information received in real time and to carry out cooperative behaviors. For example, a group of autonomous vehicles might avoid a route together because of possible risks, or a vehicle could decide to drop someone off earlier due to messages received, a foreseen crowding ahead.
Further applications(应用) of vehicle-to-vehicle communication are still being researched, including how to perform cooperative behavior.

More and more birds are flying to settle at Qinghai Lake, one of the highest inland lakes in China, thanks to the protection efforts of local governments. Covering an area of over 4,000 square kilometers. Qinghai Lake is also the country's biggest saltwater lake. Located in Northwest China's Qinghai Province, the lake is famous for the two islands at its northwest point—Cormorant Island and Egg Island. The two islands have plenty of floating grass and various schools of fish, offering rich food sources for birds. The islands have become a paradise for different kinds of groups of birds and have been called“Bird Islands”．
Each March and April, when ice and snow covering the QinghaiTibet Plateau starts to melt, over 20 kinds of birds fly to the Bird Islands to lay eggs. During the months, flocks of birds cover the whole sky over the islands and birds eggs can be found everywhere. Visitors can hear the singing of birds from miles away. These have become a world famous symbol of the lake.
To protect this paradise for birds and support calls for ecological protection, China set up the Qinghai Lake Natural Protection Zone at the end of 1997.Meanwhile, the State has pointed out the Bird Islands and Spring bay of the Qinghai Lake as central protection zones.
Inspection officials and management employees often patrol the lake, improving local residents' knowledge of related laws and spreading knowledge about animal protection to visitors. They are making great efforts to call on people to love and protect the birds. At the same time, they have built special fences around the island area to prevent wolves, foxes and other carnivorous animals, as well as illegal hunters from breaking up the birds' nestbuilding, egglaying and breeding. As a result, more and more birds are coming to the islands for sheltering and breeding.

B. Flocks of birds fly up to the whole sky over islands to lay eggs.
C. Visitors can listen to the singing of birds from miles away, but they couldn't see any bird
D. “The ice on the Plateau begins to change into water” means spring is coming.
4.The officials go around the lake mainly to________.
A. let the farmers there know the animal protection law
B. tell the farmers there some knowledge about animal protection
C. call on people to love and protect the birds

Imagine a town with crosswalks but no pedestrians, cars and trucks but no drivers. Welcome to Mcity, a fake “city” built by researchers who are testing out the driverless cars of the future.
The controlled test environment, which opened today (July 20, 2015) at the University of Michigan in Ann Arbor, covers 32 acres (the size of about 24 football fields) and contains all the trappings of a real suburb or small city. There is an entire network of roads lined with sidewalks, streetlights, stop signs and traffic signals. There’s even a “downtown” area complete with fake buildings and outdoor dining areas.
The idea behind Mcity is simple: test out new driverless car innovations in a human-free environment before these technologies are unleashed in the real world.
"Mcity is a safe, controlled, and realistic environment where we are going to figure out how the incredible potential of connected and automated vehicles can be realized quickly, efficiently and safely," Peter Sweatman, director of the Mobility Transformation Center at U-M, said in a statement.
The roads of Mcity are built to stand up to “rigorous, repeatable” testing, according to MTC officials. While Mcity drivers don't have to compete with real pedestrians, there will be one mechanical foot-traveler (a robot-like machine named Sebastian) that steps out into traffic to see whether the automated cars can hit the brakes in time. The fake city also features a traffic circle, a bridge, a tunnel, some unpaved roads, and even a four-lane highway with entrance and exit ramps, according to a report by Bloomberg Business.
In addition to evaluating fully automated, or driverless cars, the researchers also hope to test out so-called connected vehicles within Mcity’s limits. Connected cars can either communicate with one another (vehicle-to-vehicle control, or V2V) or with pieces of equipment, such as traffic lights, that are located near roadways (vehicle-to-infrastructure control, or V2I).
Even the smallest details of Mcity have been planned out in advance to copy the conditions that connected and automated vehicles could face in the real world. For example, there are street signs covered up with graffiti, and faded yellow and white lane markings line the streets.
Mcity is just one part of a much larger project that MTC and its partner organizations are establishing in an effort to get a whole fleet of connected and driverless cars on the road in Ann Arbor by 2021. In addition to the fake city, MTC is also continuing to launch connected and semi-autonomous(半自动) cars on real roadways. Eventually, the University of Michigan and the Michigan Department of Transportation said they hope to put 20,000 connected cars on the roads of southern Michigan.
