Jiangxi Province has taken many measures to protect finless porpoises (江豚),     1     have faced dramatic changes in their living environment as Poyang Lake, China’s largest freshwater lake, suffered a severe drought.

The species,    2     (list) as critically endangered by the International Union for Conservation of Nature, now lives only along the middle and lower reaches of the Yangtze River. The number of finless porpoises    3     (drop) significantly in the past few years, with only 457     4     (live) in Poyang Lake.

As the water level dropped to less than 12 meters, the lake officially entered this year’s dry season on August 6,     5     (early) than at any time since records began in 1951. Severe drought has reduced the lake by 75 percent. This change will     6     (undoubted) increase the risk of the finless porpoises hitting boats and also result     7     a food shortage for the porpoises.

Wang Liang, who works for the provincial Department of Agriculture and Rural Affairs of Jiangxi, said the province has released     8     total of 200 million fish, shrimps (虾) and crabs into the waters     9     (enrich) the food supply and more than 2,000     10     (volunteer) have been trained to rescue the species.

As a child, reading was one of my favorite     1     (hobby), and it still is to this day. I've always enjoyed immersing (使沉浸于) myself in the pages of a novel, entirely attracted by fictional characters and     2     (they) stories. One part of the experience that almost always made me feel    3     (disappoint), however, was when my beloved books became movies. And according       4     a recent survey, I'm not the only person who is let down by book adaptations.

SuperSummary, an online resource, wanted     5     (know) the answer to a burning question: Book or movie? The company asked 2,030 people, ages 23 to 62, to answer questions about books    6     had been turned into movies or TV shows.

The results were fairly close. Overall, 34% of people enjoyed the book,       7    (compare) to 27% of people who liked the movie more. Although 82% of people said “screen adaptations help books come to life,” 46% of people argued that movie adaptations “would never be as good     8     the book.”

Perhaps the slight preference for the book over the movie is related to libraries being a little     9     (popular) than movie theaters. I     10     (complete) understand why people might prefer watching a live version of a story on the big screen, but to me, there are few simpler pleasures than getting lost in the pages of a good book.

Drinking two or more cups of black tea a day     1    (be) associated with lower risk of death from all causes, according to a new study     2    (publish) Monday in Annals of Internal Medicine.

The study looked at nearly 500,000 men and women aged 40 to 69 years old who participated     3     the UK Biobank, which houses in-depth genetic and health information, between 2006 and 2010. The database included information participants reported about     4    (they) own tea drinking habits, such as     5    (frequent) and what they added to their cup.

Some participants didn’t drink black tea a tall, but since the data came from the United Kingdom, there were plenty of people who drank it     6    (regular) and some who drank up to 10 cups a day, said lead study author Maki Inoue-Choi.

The Biobank followed up about 10 years after the     7    (origin) survey, and researchers found that people who drank two or more cups of tea daily in the interim(其间) were less likely     8    (die) from causes such as heart disease.

The research is     9     exciting look into tea drinking habits, but there is still more work     10     needs to be done before recommending dietary changes, said Howard Sesso, an associate professor of medicine at Harvard Medical School, who was involved in the study.

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.”

In a first of     1     (it) kind in China, Shenzhen, a city that pioneered reform and opening-up in China, will allow fully autonomous vehicles     2     (run) on roads in certain areas without human control equipment.     3     city in Guangdong province revealed a new regulation tailored for smart connected vehicle management in China, which is scheduled to come into force on August 1.

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.

The regulation classified autonomous vehicles     6     three types: conditionally autonomous driving, highly autonomous driving, and fully autonomous driving. 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.
