In ancient China lived an artist    1     paintings were almost lifelike. The artist’s reputation had made him proud. One day the emperor wanted to get his portrait (画像) done so he called all great artists to come and present their     2     (fine) work, so that he could choose the best. The artist was sure he would    3    (choose), but when he presented his masterpiece to the emperor’s chief minister, the old man laughed. The wise old man told him to travel to the Li River～perhaps he could learn a little from the greatest artist in the world.

Filled with     4     (curious), the artist packed his bags and left.     5     he asked the villagers on the banks of the river where he could find the legendary (传奇的) artist, they smiled and     6     (point) down the river. The next morning he hired a boat and set out     7     (find) the well-known painter. As the small boat moved,     8     (gentle) along the river he was left speechless by the mountains being silently reflected in the water. He passed milky white waterfalls and mountains in many shades of blue. And when he saw the mists rising from the river and the soft clouds    9     (surround) the mountain tops, he was reduced to tears. The artist was finally humbled (谦卑) by the greatest artist     10     earth, Mother Nature.

Many people have the hobby of collecting things, e.g. stamps, postcards or antiques. In the 18th and 19th centuries,     1     (wealth) people travelled and collected plants, historical objects and works of art. They kept their collection at home until it got too big     2     until they died, and then it was given to a museum. The 80,000 objects collected by Sir Hans Sloane, for example,     3     (form) the core collection of the British Museum     4     opened in 1759.

The parts of a museum open to the public     5     (call) galleries or rooms. Often, only a small part of a museum’s collection     6     (be) on display. Most of it is stored away or used for research.

Many museums are lively places and they attract a lot of visitors. As well as looking at exhibits, visitors can play with computer simulations (模拟) and imagine     7     (they) living at a different time in history or     8    (walk)through a rainforest. At the Jorvik Centre in York, the city’s Viking settlement is recreated, and people experience the sights, sounds and smells of the old town. Historical     9     (accurate) is important but so is entertainment. Museums must compete     10    people’s spare time and money with other amusements. Most museums also welcome school groups and arrange special activities for children.

A 90-year-old has been awarded “Woman Of The Year” for     1    (be) Britain’s oldest full-time employee—still working 40 hours a week. Now Irene Astbury works from 9am to 5pm daily at the pet shop in Macclesfield,     2     she opened with her late husband Les. Her years of hard work have     3    (final) been acknowledged after a customer nominated(提名) her to be Cheshire’s Woman Of The Year.

Picking up her “Lifetime Achievement” award, proud Irene     4    (declare) she had no plans     5    (retire) from her 36-year-old business. Irene said, “I don’t see any reason to give up work. I love coming here and seeing my family and all the friends I     6    (make) over the years. I work not because I have to,     7     because I want to.”

Granddaughter Gayle Parks, 31—who works alongside her in the family business—said it remained unknown as to who nominated Irene for the award. She said, “We don’t have any idea who put grandma forward. When we got a call     8    (say) she was short-listed, we thought it was     9     joke. But then we got an official letter and we were blown away. We are so proud of her. It’s     10    (wonder).”

According to a review of evidence in a medical journal, runners live three years     1    (long) than non-runners. You don't have to run fast or for long    2    (see)the benefit. You may drink, smoke, be overweight and still reduce your risk of     3     (die) early by running. While running regularly can't make you live forever, the review says it     4     (be) more effective at lengthening life    5     walking, cycling or swimming. Two of the authors of the review also made a study published in 2014    6    showed a mere five to 10 minutes A day of running reduced the risk of heart disease and early deaths from all     7    (cause).

The best exercise is one that you enjoy and will do. But otherwise…   it's probably running. To avoid knee pain, you can run on soft surfaces, do exercises to    8    (strength)your leg muscles(肌肉),avoid hills and get good running shoes. Running is cheap, easy and it's always    9    (energy).If you are time poor, you need run for only half the time to get the same benefits as other sports, so perhaps we should all give    10    a try.

Something significant is happening to the world population-it is aging. The median(中位数的)age of an American in 1950    1    (be)30-today it is 41 and is expected    2    (increase)to 42 by 2050. For Japan, the    3    (number)are more striking-22 in 1950, 46 today and 53 in 2050. In 2015, one in 12 people around the world were over 65；by 2050, it will be one in six.

This aging of the population is driven    4    two factors. The first is declining birthrates, which means old generations are large    5    (compare)to younger generations, and so, on average, the population becomes    6    (old)than before. This is    7    (particular)true in the US. The second reason is that people are living longer. A child born in the US today has    8    very realistic chance of living beyond 100 and needs to plan accordingly.

People tend to focus on the first factor. However, greater attention should    9    (place)on longevity(长寿). It isn't just that people are, on average, living longer. It's also that they are on average healthier    10    more productive for longer. Therefore, they can work for longer, consume more and in general be a boost to the economy.

These days, it is not unusual for 10-to 12-year-olds to publish their own websites or for second and third graders    1    （begin）computer classes. At the same time, computer games are becoming increasingly popular as major publishing houses continue to develop    2    （education）computer programs for children in preschool. Also, technological know-how has become a    3    （require）for most jobs in an increasingly digital world, as the computer has become a common tool in most    4    （profession）

The Digital World is a set of volumes    5    aim to describe how digital systems influence society and help readers understand the nature of digital systems and their many interacting parts. Each volume in the set explores    6    wide range of material, explains the basic concepts of major applications of digital systems,     7    discusses the influences they have on everyday life. Because the number of possible topics    8    （be）practically limitless, we focus on a sample of the most interesting and useful applications and tools and explain the basic principles of technology. Readers    9    （encourage）to continue exploring the digital world with the guidance of    10    （we）Further Resources section featured in each volume.

Few people I know seem to have much desire or time to cook. Making Chinese     1    (dish) is seen as especially troublesome. Many westerners     2     come to China cook much less than in their own countries once they realize how cheap     3     can be to eat out. I still remember     4     (visit) a friend who’d lived here for five years and I     5    (shock) when I learnt she hadn’t cooked once in all that time.

While regularly eating out seems to     6    (become) common for many young people in recent years, it’s not without a cost. The obvious one is money; eating out once or twice a week may be     7    (afford) but doing this most days adds up. There could be an even     8     (high) cost on your health. Researchers have found that there is a direct link between the increase in food eaten outside the home and the rise in     9    (weigh) problems.

If you are not going to suffer this problem, then I suggest that the next time you go to your mum’s home     10     dinner, get a few cooking tips from her. Cooking food can be fun. You might also begin to notice the effects not only on your health but in your pocket.

China plans to complete the construction of a space station and have    1    put into operation around 2022, said Zhou Jianping, the chief designer of China's manned space program, at a forum (论坛)    2    (hold) in south China's Guangdong Province. The space station,    3    could be enlarged if needed,    4    (design) to weigh 100 tonnes and accommodate three astronauts, according to Zhou.

“The main goal of the construction or the space station is to enable China to become a country    5    (independent) mastering the technology for long term manned flight in near Earth space, and having the capacity to carry out long-term manned scientific    6     (experiment) in near Earth space and comprehensive development and utilization (利用) of space resources,"    7    (say) Zhou at the 4^th China Summit Forum on Human Factors Engineering, which was held at SunYat-sen University from Saturday to Sunday.

The space station will be built as China’s main platform for space science research    8    the intention of mastering the technologies in constructing and    9    (operate) large space facilities, the technologies that guarantee life and health of astronauts who often fly in orbit, and the construction of a    10    (nation) space lab, according to Zhou.
