Eating an unhealthy diet might be more deadly than smoking, a study finds.

More than 130 scientists studied people’s eating habits in 195 countries, and held the strong     1     (believe) that poor unhealthy eating is responsible for 20% of all     2     (die) worldwide. That makes unhealthy eating more dangerous than any other cause of disease.

Part of the problem is     3     people are eating, like meat, salt, sugary drinks, and other unhealthy foods, including those     4     (contain) lots of fat . People are filling their bodies     5     too much of the wrong kinds of food. In general, people are eating 86% more salt than they should. While salt is a     6     (necessary) to our body, too much can lead to heart disease. Salt sometimes can be very tricky, because unlike eating meat or drinking a sugary drink, you may not know you’re eating     7    . Most of the salt people eat has already been added to food items by the companies that make them.

But a bigger problem     8     (be) what people are not eating, such as nuts, fruits, and vegetables.

Lead scientist Dr Ashkan Afshin said, “Eating too many fatty and sugary foods affects people from all walks of life. We are pointing out the importance of low consumption (食用) of healthy foods as compared to the greater consumption of unhealthy foods.”

The scientists say governments can’t just call on people     9     (eat) healthily. They also suggest that farmers     10     (encourage) to grow more of the kinds of foods that people need to eat.

It was because of the photo     3     he was awarded the Pulitzer Feature Photography. In the photo, a hungry eagle was concentrating     4     a starving African girl, waiting for her death. Readers were shocked by     5     photo. Meanwhile, they were skeptical (怀疑的) about Kevin’s motivation. Some thought Kevin     6     (deliberate) placed the girl there so as to shoot the photo. Many accused him of    7     (kill) the poor girl. They all agreed that Kevin should feel     8     (guilt) about the girl’s death. Faced with the     9     (accuse), Kevin was in a dilemma. He denied his purpose for money and fame     10     he couldn’t return to his normal work because of too much stress. Troubled by the conflict between professionalism and morality, in the end, he made suicide (自杀) three months after the famous photo came out.

Across northern Africa, the desert is steadily growing. Dry lands are spreading. But a bold project known as the Great Green Wall aims to stop the     1     (grow) of the desert. The ambitious program includes plans     2     (help) protect and maintain resources and fight poverty.

Farmers are learning to care for their land and use water     3     (wise). They are also planting millions of trees and crops. The Great Green Wall would cover     4     area of more than 4,000 miles --from Senegal in the west to Djibouti in the east.

The Great Green Wall     5     (approve) by the African Union in 2007. The program receives support from the United Nations, the World Bank, and other groups.

The Great Green Wall’s trees provide a barrier     6     desert winds and help hold moisture(水分) in the air and soil,     7     (allow) crops to grow. In time, the richer soil will provide more land for animals to graze on. More resources will bring more jobs. “The goal is to create sustainable land management,” said Nora Berrahmouni, a forestry officer     8     works with the UN Food and Agriculture Organization.

Trees and crops have been planted in Senegal and Niger. An     9     (add) benefit of the Great Green Wall is that countries in the region are sharing information about which programs work and which don’t. Now, along with trees,    10    (idea) are taking root.

On September 17, 2019, Yuan     5     (award) the “Medal of the Republic” by President Xi Jinping.

However, if you are a member of a travel group, your schedule is beyond your control. Guides may lead you to some places     7     you don’t want to go.

Apart from that, self-driving tourism offers you many     8     (opportunity) to spend some happy time with your family. During the tour, you help and encourage each other when tired.     9     (obvious), the emotional connections would become closer after an     10     (enjoy) tour.

Traveling abroad is gaining more    1     (popular). Therefore, in order to leave a good impression on foreign people and avoid getting     2     (you) into trouble, it is important to know the things that you should never do when you are visiting another country. In Japan, don't tip anyone. Tipping is just not part of     3    culture. If you leave the tip on the table, they will come running after you with it. Do not enter some certain places     4    your shoes on. For example, some     5     (tradition) Japanese restaurants require you to take off shoes before     6    (enter). Just follow suit and you won't go wrong. When you're in Russia, never give even number of flowers as a gift. That's for dead people. A proper bouquet (花束) should consist of flowers with the number like 1, 3, 5, 7, etc. In some holy (神圣的) places like temples in India, trousers or dresses     7     show   anything above the ankles are considered unacceptable and therefore     8     (official) banned. This     9     (apply) to both sexes. If you're in Singapore, don't feed birds, bring pets into public, or eat or drink on public transport. All of these actions will get you     10     (fine).

There are certain similarities and many significant     1    (differ) between the modern     2     ancient Olympics. The similarities are: both are held every four years. They have     3    (run) races. Also there is no prize money for winners.

However, there are differences between them. In ancient Olympics, there was only one set of Games. And no women and no slaves could take part. The     4    (compete) only came from Greece. In modern Olympics, there     5     two main sets of Games -- the winter and the summer Olympics. Only     6    (that) who have reached the     7    (agree) standards for their event will be admitted     8     competitors. They may come from anywhere in the world. There are over 250 spots. And each one has its own standards. Women are not only allowed, but also play     9     very important role in almost all the events. Hosting the Olympic Games is a great honor. The motto of the Olympics is:     10    (swift), Higher and Stronger.

Rare Piece of Chinese Art Found at US Home Sale

A small bowl     1     (buy) for $35 at a home in Connecticut turned out to be a rare piece of ancient Chinese art. The bowl is worth between $300,000 and $500,000. It     2     (go) up for sale at an auction to be held by Sotheby's (苏士比拍卖行).

Sotheby's says the object was found at a yard sale in the New Haven area last year. A collector of     3    (antique) saw the bowl at the sale, paid $35 for the bowl and later emailed information and photos to Sotheby's asking for     4     estimate of its value.

McAteer said all the information helped them identify it as a product of the early Ming period. But now only six other such bowls are known to exist, most of     6     are in museums.     7     the bowl ended up at a Connecticut yard sale remains a mystery. It is possible that the bowl     8    (pass) down through generations of the same family who did not know how special it was.

McAteer said. "It's always really     9    ( excite) for us as specialists when something that we didn't even know but existed is     10    (seeming) out of nowhere.
