【题目】 Families should reduce exposure to synthetic chemicals found in food colorings, preservatives and packaging materials as a growing body of research shows they may harm children’s health, according to a policy statement and technical report from the American Academy of Pediastrics released online.

The statement also suggests improvements to the food additives regulatory system, including updating the scientific foundation of the U.S. Food and Drug Administrations safety assessment retesting all previously approved chemicals.

Leonard Trasande ,the author of the policy statement, to tell us more about these concerns.

The scale of consumers of fast food delivery service in China

The fast food delivery service, which depends on the already-existing restaurants, can cover a larger place with more customers without taking the seats of restaurants. Under the current economic and market condition, the fast food delivery service has been the new battlefield of the fast food giants in China. Even MacDonald’s and KFC, the two international fast food giants are fighting against each other for more market share in China’s fast food delivery industry.

However, Jing Linbo, Deputy Director of the Institute of Finance and Trade Economics, the Chinese Academy of Social Science, thought that the fast food delivery is the new growth point of fast food enterprises. But the fast food enterprises should have certain comprehensive strengths to do this service, which is thought to be different from the traditional food industry in some aspects.

Besides, with the development of the new industry, there also emerge problems. And some observers have given their warnings. They warn that if the fast food enterprises take no notice of the hidden problems, they will lose the customers in the competitive market gradually.

【题目】Directions: Fill in each blank with a proper word chosen from the box. Each word can be used only once. Note that there is one word more than you need.

For several decades, various types of artificial intelligence kept shocking the world. Robots could 1 people in highly competitive games and then quickly destroyed their human competitors.

AI long ago mastered chess, the Chinese board game Go and even the Rubik's cube, which it managed to solve in just 0.38 second.

Now machines have a new game that will allow them to 2 humans: Jenga, the popular game in which players 3remove pieces from an increasingly unstable tower of 54 blocks, placing each one on top until the entire structure would 4.

A newly released video from MIT shows a robot developed by the school's engineers playing the game with surprising accuracy. The machine is equipped with a soft gripper(夹子), a force-sensing wrist and an external camera, allowing the robot to detect the tower’s 5 the way a human might do

Unlike in purely recognitive tasks or games such as chess or Go, playing the game of Jenga also requires mastery of physical acts such as pushing, pulling, placing, and arranging pieces. It must 6 interactive physical operation, where you have to touch the tower to learn how and when to move blocks.

Imitating it is rather difficult, so the robot has to learn in the real world, by working with the real Jenga tower. Recently, a relevant research was published in the journal Science Robotics. Researchers say the robot demonstrates that machines can learn how to perform certain tasks through actual touching instead of relying heavily on visual 7. That physical 8 is significant, researchers say, because it provides further proof that robots can be used to perform 9 tasks, such as separating recyclable objects from landfill trash and assembling consumer products.

In a cellphone assembly line, the felling of any component is coming from force and touch rather than vision. To become an accomplished Jenga player, the robot did not require as much repetitive practice as you might imagine. Hoping to avoid reconstructing a Jenga tower thousands of times, researchers developed a method that allowed the robot to be trained on about 300 games. Researchers say the robot has already begun facing off against humans, who remain 10 playersfor now.
