China used to be called the “Kingdom of Bicycles” in the 1980s and the 1990s, but since then, cars     1     (take) over the country. Because of traffic jams,     2     can be difficult to travel across major Chinese cities. Even     3     (go) a few kilometers can take up to an hour. Now, new apps     4       help people use bikes are being used more and more across cities.

Cheng Li started using bike share services about six     5     (month) ago. He said now he was using a car less and the metro (地铁)     6       “After I get off the metro, I usually have to walk another kilometer or two, so I’ll grab a bike share and go. It is convenient.”

For many, it is great to have shared bikes.     7    , many of its bike share stations were not placed in convenient places. Now, it is easy to find a bike, and to register with     8     smartphone.

Meanwhile, there is now a lot of     9     (compete) among bike-sharing providers because of their popularity. Some providers are trying to flood the streets with bikes to be more visible. Sometimes there are so many bikes that they     10    (complete) block the sidewalks.

Be a Good Tourist

Tourism can be both good and bad. It brings in money and jobs     1     the local people. However, it may also bring some problems. Some travelers,     2     want to prove they have visited the place, use paint, rocks or even     3     (key) to write on the walls or stones there. As     4     result, thousands of tourist sites     5     (destroy) so far. Another problem is that too many travelers may cause trouble to the local people. Take Sanlitun (三里屯) in Beijing for example, some travelers love to party there late into night, making it     6    (difficulty) for locals to sleep.

The number of problems from tourism     7    (be) endless: taking pictures of local people without     8    (ask) for their permission, crossing roads in large groups with no traffic laws in mind, and many more. The only way     9    (solve) the problem is to make sure that you are not one of them! Be the best,     10    (kind), most polite traveler possible.

Did you grow up in one culture, your parents came from another, and you are now living in a     1     (total) different country? If so, then you are a third-culture kid.

The term “third-culture kid”     2     (use) in the 1960s for the first time by Dr. Ruth. She first came across this phenomenon while     3     (research) North American children living in India. In general, third-culture kids benefit     4     their intercultural experience and they often reach excellent academic results.

Yet many     5     (difficulty) may arise from this phenomenon. Third-culture kids may not be able to adapt     6     (they) completely to their new surroundings. Also, they often find it hard     7     (develop) new friendship. Additionally, for a third-culture kid, it is often     8     (easy) to move to a new country than to return to his homeland. For example, after living in Australia for many years, Louis finally returned to the country     9     she was born. She didn’t know anything about current TV shows     10     fashion trends. And she didn’t share the same values as other teens of her age.

People used to keep large amounts of cash at home during difficult times.     1     in the coronavirus (冠状病毒) crisis, things are different. These metal coins and paper bills can be a    source of worry rather than hope.

The fear is that these objects, possibly     2     (touch) by thousands of people, could be a way for the disease to spread. Health experts say that     3     risk is small. Still, some businesses refuse to accept them, and some countries have suggested that their citizens should stop     4     (use) them altogether.

Britain and Australia are leading the trend in     5     (expect) of going cashless in the near future. Sweden, Finland and Canada have also     6     (gradual) reduced cash use to the point where using it in large amounts seems unusual. And in China, cash use     7     (drop) dramatically as electronic payment services increased in popularity over the past ten years.

Though in Iran there are no international bank cards, new signs have appeared at some gas stations. Service     8     (do) through debit cards (借记卡) only, making the payment process much     9     (easy).

Then will cash disappear? Probably not in a short time. Cash use is still common in places     10     many people cannot pay for the cost of banking services, like countries in West and Central Africa. And technology is also a problem. Experts say the world will not be cashless until everyone and every country has reliable access (能使用) to the internet.

For some people in China, the aim of travel is to create 15-second    1    (video). It’s not about where you have been, but about where you’re seen to have been.

    2    (situate) on cliffs above a river, Hongyadong is a stilt house complex(建筑群) in Chongqing . The bars, restaurants and golden neon lights    3    (be ) a popular draw since it was built in 2006. Last year the number of visitors increased sharply.

The main reason, it seemed, was Hongyadong’s sudden popularity on an app, Douyin,    4     aim is not to produce a well-crafted video, but    5    (simple) to show that you have also been to the popular places. The beauty of the attraction is less important than the fact    6    people are flocking there to daka.

A subculture of young people who embrace daka as a lifestyle has developed. So-called daka zu--- “daka tribes”---can    7    (find)hanging out in various scenic spots,    8    (check) out as many hot locations as possible within a single day.

The daka craze may have practical origins. China’s young urban professions don’t have so much free time. Sometimes, they need to work overtime. So they have to make    9    best use of their limited leisure time. Douyin captures the mood with    10    (it) slogan: “Make every second count”.

If you write your name with your left hand instead of your right, you are left-handed,     1    . writing is not the only standard. You can write with your right hand, but if your dominant(主要的) and for cleaning teeth, combing hair,     2       (cook) and working is the left one, then you are a left-hander. About 10% of the people in the world are left-handed.

Scientists are not sure why people use one hand     3     (much) than the other, but it seems that it is somehow     4     (relate) to our DNA. So genes may play     5       part here. This might explain     6    . there are so many left-handers in the British royal family. Whatever the reason is, the world     7     (set) up for right-handed people, which makes it more dangerous for left-handers.

We live in a right-handed world. There are lots of tools and machines that are harder     8     (use) for left-handed people like cameras and guitars. A left-hander may have aches and pains,     9     (most) in the arm,   hand   and   back. There   are   also more   health   risks   for   left   handed workers who use   dangerous       10     (equip) or tools designed for right handed. Whether you are left-handed or right-handed, it is best to let children use the hand that they find most natural.

10 . A sand storm often takes place in the northern China,     1    is a kind of natural disasters. China usually experiences this kind of weather between February and May, while March and April see the most frequent and the     2     (strong) sand storms. It becomes a very important environmental problem. It does lots of harm     3    the society as well as the environment.Firstly, the strong wind destroys soil and plant cover by     4     (bury)fields with sand and dust. Secondly, by leaving too much dust in the air it will     5     (serious) pollute the air. Thirdly, a sand storm will have     6    bad effect on transportation. The dust in the air makes traffic and aircraft movements more difficult. And when the sand buries the roads, the traffic will     7     (block). When plants in the farmland are buried, food supply will lose.

Sand storms are another     8     (punish) nature gives to mankind. We should not only take effective measures     9     (stop) them, but also draw some     10     (lesson) from them. We should not develop the economy (经济) at the cost of the natural environment.
