Tea is a healthy drink. Drinking tea in China could be considered as an art and to help people achieve a sense of calm and renewed energy. It is also     1     way to enjoy life better.

Stories     2     are about the discovery of tea are different depending on the people who you ask, but we know that Chinese people have been drinking tea since Shennong, 5,000 years ago. Usually, tea     3     (believe) to be medicinal, and is so central to     4     (day) life that an old Chinese saying includes tea in a list of seven important contents to be gathered each morning, along with firewood, rice, oil, salt, soy and vinegar.

Tea serves three primary     5     (purpose) traditionally in Chinese society: to show status, to bring people together and to improve wellness.

Drinking tea together is a sign of respect. In ancient times, “tribute tea”(贡茶) was     6     (special) kept for and presented to the Emperor. Tea still has a place in the life of the average people. It is common     7     (give) guests a cup of tea to welcome them into the home. But tea is more than a key of social customs. It is meant to act     8     a medium through which people can become much     9     (close) to nature. Drinking tea out in nature will create a spiritual connection to the environment and make people feel     10     (relax).

Online grocery shopping is convenient and continues to grow in popularity. But a new study     1     (publish) in Public Health Nutrition shows that many online products do not have information about ingredients or nutrition     2    (fact), which is a huge miss.

Required information was present, obvious and readable for only 36. 5% of observations.     3     is even more troubling, researchers say, is that non-required information, such as claims like “low in fat” or “organic”, was displayed on 63.5% of the products.

Labeling information     4     (be) important for all consumers so they can make informed (明智的) choices when grocery shopping. People may use the information label     5     (determine) sodium and potassium (钠和钾) to manage heart or kidney disease or may focus     6     sugar, fiber, or carbohydrates to manage diabetes (糖尿病).

Food retailers should     7     (immediate) change their practices and disclose the full information label clearly, consistently and readably. “    8     (difficult) in finding necessary information on some products could actually pose (引起)     9     immediate danger of a severe reaction or even death to the most sensitive consumers,” a researcher says.

The researcher also points out the availability of food labels     10     (make) a difference to the quality of our food choices at the population level. Not having this information potentially weakens the general public health.

The first domestic chickens we have found lived no earlier than 3,670 years ago, suggesting they have a far shorter history than we thought. These birds don’t seem to have been raised for their meat,     1     (make) it unclear what drove domestication. The chickens alive today descend from a wild bird native to South-East Asia     2     (call) the red jungle fowl, but exactly     3     domestication occurred was unclear. Some researchers have estimated that the first domestic chicken lived more than 6000 years ago, while others claim     4     (find) chicken bones at 10,000-year-old sites.     5     analysis by Ophelie Lebrasseur at the Centre for Anthropobiology and Genomics of Toulouse in France and her team concludes that the     6     (early) clear evidence of domestic chickens appeared between 1,650 BC and 1,250 BC at a site called Ban Non Wat in central Thailand. Not only     7     (be) chicken bones superabundant at the site, but there are signs that people were buried with the birds,     8     Lebrasseur says makes a domestic relationship clear. Lebrasseur and her team suspect chicken domestication might have been triggered by the       9     (appear) of cereal fanning in South-East Asia. “This created a more open, less tree-covered environment, which is actually an environment where red jungle fowl thrive,” she says, “And they could have fed     10     the waste from human societies.”

When I was in primary school, I disliked doing exercise. I felt tired when I did any kind of exercise. My parents were really     1     (worry) about my health. One day, after having supper, my father     2    (come) and asked me to have a walk with him in the park. I agreed and we went     3     together. It was hard for me to walk for half an hour. I wanted to give up,     4     my father encouraged me to keep on walking. From then on. I was often asked to walk with my parents. To my surprise, I could walk for an hour in the     5    (five) month. How     6    (pride) I felt! I loved taking exercise gradually. Now I am     7     excellent runner in my school. I take part in the school sports meeting every year.

During all our life, we may face a lot of     8    (difficulty). Don’t be afraid of     9    (they). Please try to face them     10    (brave). After you overcome what you used to be afraid of, you may find how great you are!

The new regulation, which is set to fill the legal gap for domestic intelligent connected vehicles, said automakers don’t     4     (necessary) have to equip fully autonomous vehicles with manual driving mode and corresponding (相应的) devices, and nor do they have to have human drivers.

But such fully autonomous vehicles can only drive on certain roads and sections     5     (select) by Shenzhen’s traffic management department, according to the regulation, which was published on the official website of Shenzhen Municipal People’s Congress.

Conditionally autonomous and highly autonomous vehicles must have manual driving modes and corresponding devices, and     7     (equip) with drivers.

Meanwhile, the regulation     8     (clarify) rules for responsibilities and auto insurance coverage in the event of car accidents     9     involve autonomous driving, which is expected to promote the fast     10     (develop) of self-driving vehicles.

Nowadays, vegetarian(素食主义的)eating is becoming more popular. Although it does have a good reputation for     1    (benefit)our health, recent news has focused on what could be bad about vegetarian diets,     2    (include)stroke risk, harm to brain health, hair loss and depression.

British researchers     3    (follow)more than 48,000 men and women with no history of heart disease or stroke for about 18 years. Vegetarians had a 20%     4    (high)rate of stroke than meat eaters. Another expert wrote that the trend towards vegetarian diets may lead to a choline(胆碱)crisis, Choline is a nutrient(营养物)    5     is important for brain health and other functions. It can     6    (find)in meat, and our body can’t make all that humans need.

So, can giving up meat lead to hair loss? A recent report found that a severe lack of protein, among other diet shortcomings, can lead to it. That’s     7     meat contains iron, vitamin B, and zinc, which are all important for hair     8    (grow).

Can vegetarian and vegan diets affect our mood? Research on this is mixed. Some studies have found that going meatless     9    (improve)mood, but others have found     10     opposite. In one study of 400 new mothers, 80 of them suffered from postpartum(产后的)depression. A vegetarian diet was one factor that seemed to make it more likely to be depressed.

The compass, gunpowder, papermaking, and printing are the “Four Great Inventions” of ancient China which are celebrated in Chinese culture for their historic     1     (significant). As early as the Tang Dynasty (618-907), the Chinese     2     (invent) block printing. In block printing, characters are carved out to make a wood-block printing plate. It is then used to print text. Diamond Sutra, an ancient Buddhist text     3     (print) in the year of 868 and discovered at Dunhuang Cave in 1900, is the     4     (old) printed book in the world.

Block printing is a     5     (cost) and time-consuming process, as each carved block can only be used for a specific page and     6     single mistake in carving could ruin the whole block.     7     (overcome) this, Bi Sheng (990-1051) invented movable-type print g during the Song Dynasty (960-1279). Individual characters are carved on identical pieces of fine clay,     8     are then hardened by fire. The pieces of movable type can then be glued to an iron plate and easily detached (分离). Each individual character can then be installed to print a page and then rearranged as it     9     (need). When the printing is finished, the pieces are put away     10     future use.
