It is no doubt that health is the most important thing in our life.As a Chinese proverb go, “Health is blessing”.Should we be always ill in bed, how can we enjoy life?
To keep healthy, we must develop a healthy way of life.First of all, we should keep on doing sports on a regularly basis, because it can strengthen both our body and mind, refresh ourselves and making us work more efficiently.Secondly, we must keep balanced diet to provide our body with various nutrition we need, but we should refuse junk food.Remember, it is through the mouth where diseases enter into our body.Thirdly, a good sleep is also vital to our health.Stay up too late at night often results in poor health.As middle school students, we need better sleep to do better in our lessons.

What's more exciting than having a fresh hot pizza delivered to your door? How about having it brought to you by a robot? Thanks to Domino's Robotic Unit or DRU, that just became a reality! On March 8, the three-foot tall robot delivered its first pizza to some lucky residents in Brisbane, Australia.
The fully autonomous DRU is the result of a cooperation between Domino’s Pizza Australia and Marathon Robotics.The 450-pound machine that travels at a maximum speed of 12.4 miles an hour can traverse a distance of up to 12 miles and back, before requiring a battery recharge. LIDAR, a laser-based sensor technology similar to the one used in self-driving cars, enables DRU to detect and avoid obstacles, while traditional sensors, much like those used in vacuum robots ensure its path is safe as it heads to its destination.
The robot can fit up to ten pizzas and even has a separate cold area to accommodate drink orders.To access their fond, customers have to enter the unique code provided by the company.This is not only ensures that they pick up the right pizza, but also prevents the pies from getting stolen.
Scientists expert additional DRU’s to be ready for service in their various Queensland locations within the next six months.But don’t expect these super cute robots to replace humans anytime soon.According to Domino’s the DRU still needs extensive testing, which the company believes could take up to two years.
And then there is also the issue of regulations.The public use of autonomous vehicles is still banned in most countries.But Don Meij, the CEO and Managing Director of Domino's Pizza Australia New Zealand Ltd, is not worried.He is “confident that one day DRU will become an integral part of the Domino's family.”
1.What's the function of LIDAR?
A. keeping DRU free of obstacles
B. Recharging DRU’s battery
C. Helping DRU find its destination
D. Protecting DRU from bad weather
2.What does the underlined word “accommodate” in Paragraph 3 probably mean?
A. Heat B. Hold
C. Sell D. Show.
3.Why does the company provide codes for its customers?
A. To fit up more pizzas
B. To prevent the pizza being taken by mistake
C. To keep the pizza warm
D. To get the pizza paid in time
4.What can we infer about the future of DRU?
A. It may need some improvements B. It will replace humans soon.
C. It may be banned in Australia D. It will soon be applied worldwide
