My interest in Chinese food started years ago, when I was a young reporter for the Washington Post. Our office wasn't far from Chinatown,      I found some very good Chinese restaurants.

    That was the first time that I      (notice) the fresh taste of the meat and vegetables of Chinese food.

    When I learned more about the food, I began to understand why      has this special feature.

    Many years ago, china had      energy crisis because it lost much of its wood due to over population and poor management of its forests. This      (lose) was very bad for the country, of course, but it turned out to be very good for the food. Wood became very expensive and hard to get, so the Chinese had to either find a substitute for their      (value) wood, or learn how to use it better. There weren't any substitutes so people found ways to economize.

    In order to economize in cooking, they had to use very little wood. So they started cutting their meat and vegetables      small pieces before they put them in the hot oil. That way, the food cooked      (fast) and they saved more fuel. The food      (prepare) in this way kept its fresh flavor and it's this flavor      attracts people from other countries to the art of Chinese cooking.

    Old Tom had four sons. He wanted them      (learn) not to judge things too quickly. So he sent them to look at an apple tree in different seasons. The first son went in winter, the second in spring, the third in summer, and the youngest in autumn. When they all came back, he called them together to describe      they had seen. The sons had different      (opinion). Tom then told them that they shouldn't judge a tree, or a person, by only one season.

    Everyone      (love) snow. But when school stays open despite the snow, it can be really annoying. However, there is one upside of going to school      a cold winter day: you might be smarter. So far, researchers who study the brain      (find) that cold temperatures make us think more quickly since messages travel faster among our brain cells. So the scientists say      (hang) out on a cold morning may boost the result of any test that day.

    Modern-day robots are programmed to handle tasks that are normally carried out by humans. They are faster and      (accurate) than human workers and never ask for a pay rise or take breaks!

    Robots are also able to work      dangerous situations.

    Researchers at the University of Arkansas in the United States say that the mobile robots which have been created already are ideal for the job of hospital attendants. These mobile robots store a      (detail) map of the hospital in their memory. The robots' sensors can detect      (object) and quickly get out of the way. Although these robots cannot go up and down know how      (press) a button of an elevator.

    Researchers at a Massachusetts' university are creating the first robot       can constantly change its shape according to the task it has to do. These are called polymorphic robots. "Polymorphic" means      ability to take different forms. A 3D printer      (place) inside the robot to create the desired shape. The entire process of changing forms in this manner is called the rapid printing technology which is      (fair) common in the car industry to produce complex 3D structures quickly. Once the robot has performed      (it) task, it can be melted down and recycled into another useful part by the 3D printer.

    Chinese might be heard when you take a ride on the street. Turning to the right, you see a Sichuan-style restaurant. After        (walk) into a store, you see that Huawei smartphones are on sale. But you're not in China — you're in Manchester in Britain.        fact, you might see similar things in many other cities. Chinese products have been going global.

    Western countries        (enjoy) Chinese food for a long time. Chinese restaurants have made some changes to the dishes        (meet) local people's tastes.

    Some Chinese       (brand) are also becoming more popular. In many cities in Europe, stores sell TCL televisions, Haier fridges        Lenovo computers, reported Reuters. They're not simply made in China, but        (design) in the country.

    In the past, most Western people thought Chinese products were cheap but not        (rely). Things have changed greatly, though. For example, Huawei.        is one of China's major smartphone makers, overtook Apple in worldwide smartphone sales for the first time in June and July, behind only Samsung. "They are       (beauty) and offer some unique features American phones don't have, " CNN once said about Chinese smartphones.
