1 . Baidu, a Chinese search engine and artificial intelligence firm, announced its latest electric autonomous driving vehicle, Apollo RT6, on Thursday. The new vehicle is a fully electric vehicle with a steering wheel (方向盘) that can be removed when not required. It will cost ¥250,000 per unit.
“The steering-wheel-free design allows more space for extra seating or other additions and the massive cost reduction will enable us to put tens of thousands of autonomous vehicles into operation across China,” Robin Li, co-founder and CEO of Baidu, said at the firm's Baidu World Conference Thursday. “We are moving towards a future where taking a robotaxi will be half the cost of taking a taxi today.”
Baidu already runs Apollo Go and Apollo Moon, taxi services using self-driving robotaxis with safety staff seated in the driver or passenger seat. They have been in operation in big cities like Beijing, Shanghai, Shenzhen and Guangzhou, although the service is limited to specific areas. The new vehicle will soon join those robotaxis.
The RT6 has reached the industry's Level 4 out of five possible levels of technology. That means its systems can operate without a driver but must be pre-loaded with a detailed map, thus limiting the areas where the vehicles can operate. Lower levels of self-driving technology have been available for decades. For example, many Level-3 vehicles allow hands-free highway driving. Other kinds of self-driving robot vehicles are already widely used in factories warehouses and other tightly controlled settings.
Compared to previous generations where the technology was mainly used on conventional vehicles, the Apollo RT6 was designed specifically with fully autonomous driving in mind.
Baidu is best known for its search engine and online advertising services, but in recent years it has invested heavily in autonomous driving and artificial intelligence technology, including automated personal assistants and AI chips.

2 . Which is more important for parents, making more money to give the kids a better life or spending more time with them? It is a problem for parents and it is not easy to decide. A new study shows that today’s parents are spending more time with their children than parents in the past. According to the study, today’s college-educated mothers spend about 21.2 hours a week taking care of their children. But women with less education spend about 15.9 hours. Before 1995, it was only 12 hours.
Dads are spending more time on ball games. Before 1995, fathers with college educations only spent about 4.5 hours a week playing with their children. Today, it increases to 9.6 hours a week. For fathers with high school education, the time goes up from 3.7 hours to 6.8.
These days, parents don’t care more about the cleaning or the cooking. They are trying their best to spend time with their families. As for the kids, they don’t mind how much time their parents spend with them. They just want to enjoy the time their parents do be with them.
So, take part in the kids’ activities when you are with them, such as helping with homework or playing soccer with them.

3 . Thanksgiving isn’t just a holiday in the US. Some other countries have their own versions of Thanksgiving.
Brazil
Legend has it that Joaquim Nabuco, Brazil’s first ambassador (大使) to the US, enjoyed the American holiday so much that he persuaded his government to set up a similar day of thanks. Dia de Acao de Gracas is also celebrated every year on the fourth Thursday of November to give thanks for the fall harvest. The Brazilian holiday ends with a colorful and noisy carnival(狂欢节) and parade.
Japan
Japan’s version of the holiday, called “Kinro Kansha no Hi” or Labor Thanksgiving Day, is observed on November 23. It originated from an ancient rice harvest festival called Niiname-sai. Later, the holiday’s purpose was to celebrate the rights of workers. Today, Labor Thanksgiving Day is mainly observed with small acts of community service. Children often mark the occasion by handing out thank-you notes to firefighters, police officers, and other frontline workers.
Canada
Thanksgiving in Canada is a low-key affair with no big parades or retail sales. The holiday mainly focuses on families and friends getting together for a meal. While many parts of the country get the day off, it is an optional (可选择的) holiday in Prince Edward Island, New Brunswick, Nova Scotia, Newfoundland and Labrador. As a result, the celebrations often take place the weekend before the holiday.
Ghana
Ghana celebrates its version of Thanksgiving in August or September. As the story goes, the Ga settlers arrived in Ghana in the 16th century after facing lots of hardships during their travels across Africa. They celebrated their first harvest in Ghana with a feast, and a tradition was born. Before the festival, there is a month-long ban on noise, especially drumming. Similar to Thanksgiving, Homowo is a festival of food.

4 . In school, kids are told to drink water in class.
For many years, people have followed the unofficial advice of drinking eight 8-ounce glasses of water a day, known as the “8×8 rule”. It’s said that this seems to have partly come from the guidance that was published almost 80 years ago. In 1945, the US Food and Nutrition Board of National Research Council advised drinking one millilitre (毫升) of liquid for every recommended calorie of food. This is equal to around two litres of water a day, or eight glasses per person.
There are, of course, undeniable benefits to drinking water.
So, next time you feel thirsty, reach for a glass of water, but otherwise, don’t worry about it!
| A．Your body knows what it’s doing. |
| B．Is that the probable origin of the “8×8 rule”? |
| C．So should we control our water intake at all? |
| D．Yet the reality is that individuals have different needs. |
| E．After all, drinking more water is far from unreasonable. |
| F．Announcers encourage us to remember our bottles on public transport. |
| G．Water helps our bodies regulate temperature, aids digestion and acts as a shock absorber for our joints. |
5 . It’s OK to do a little comfort shopping, especially in these tough times.
Make a budget. Don’t just think about it in your head. You have to write it down. If it’s not written down, then it’s not a budget. Once you’ve taken into account the necessities like food, shelter and savings, don’t forget to put aside some money for fun. Whether your fun budget is $5 a week or $50 a week, it’s important to set that money aside. Money is not just meant to be responsible with.
Before you reach for the fun-budget money, make sure that what you are buying is a love, a thing that will bring you lasting joy.
Sound familiar? We have all purchased some wants — whether it’s a T-shirt or a bag that are now gathering dust in the closet,
| A．These things may give you lasting joy |
| B．These wants are particularly damaging |
| C．Don’t worry if it doesn’t come easily at first |
| D．Be cautious about things you just like or want |
| E．You’re also supposed to use it as a tool to make your life enjoyable |
| F．But don’t let stress-spending get in the way of your long-term saving goals |
| G．Imaging your future self is a joyful way to think about saving for your future |
6 . Dorothea Dix was born in 1802 in Massachusetts. When she was 12 years old, she left her unhappy home to live with her grandmother in Boston. There Dorothea went to school and was so quick at her lessons that two years later she went back to Worcester, Massachusetts and taught in a school for little children. She was only fourteen and rather small for her age. Anyway, she proved herself a good teacher, and the children loved her and respected her. In 1821, she opened a school for girls in Boston.
Gradually, her health broke down, and she began to think that she could never work any more, but after a long rest in England, she came back to America and did something far greater than teaching. She went through the whole country where she first observed the inhumane treatment of the mentally ill. During Dorothea’s traveling for nearly two years throughout the state, and meeting similar conditions, she always spoke kindly to the ill-treated, but she spoke wrathfully to the men who ill-treated them. In January 1843, she submitted to the Massachusetts legislature (立法机关) a detailed report of her fully documented findings.
In the next 40 years Dorothea inspired legislators in 15 US states and in Canada to establish state hospitals for the mentally ill. Her continuous efforts directly affected the building of 32 institutions in the United States. When the Civil War broke out, she went straight to Washington and offered to nurse the soldiers without pay. She hired houses to keep supplies in and bought an ambulance. She gave her time, strength and money to her country.
Dorothea Dix has been called the most useful woman of America. She is an, American educator, social reformer and humanitarian whose devotion to the welfare of the mentally ill led to widespread reforms in the United States and abroad.

7 . The maleo (塚雉), a bird with black feathers and a pink chest, is native to Indonesia’s Sulawesi island and a few neighboring ones. The International Union for Conservation of Nature (IUCN), which identifies wildlife across the world currently facing threats, estimates only 800 to 1,400 adult maleos remain in the wild. Experts do not know how many maleos still live across West Sulawesi island. They were only able to record the presence of nesting grounds in 23 villages based on reports from locals in the area. But of those, only 18 are considered active nesting areas.
Recently, the birds have been faced with new threats, which accelerate their decline. The Indonesian government plans to move the nation’s capital from Jakarta to a new city on Borneo island, which is just a six-hour boat trip apart from Sulawesi island. The island takes on the building of new roads and seaports to be used to transport materials to the new capital. Activities also include tree clearing, digging, and removing stones. The process already has changed the forest environment on West Sulawesi and is harming maleo nesting areas near the beach. These changes have made the trip for maleos to lay their eggs increasingly difficult.
Another problem has been poachers. The Associated Press reports that, regardless of official ban, they steal maleo eggs that the males’ parents have hidden in the sand, and sell the eggs for about $1 to people as food. The eggs are a traditional gift for many people in Mamuju and other parts of Sulawesi.
“As far as I know, maleo birds are in decline,” said Andi Aco Takdir, chief of the West Sulawesi Forestry Agency. He pointed to several reasons for the decline, including destruction of beach areas, and expanding human development activities. He added that government officials there are prepared to take steps to protect the maleos even with the new capital development. Andi said, “Nature conservation must be used as an achievement and must not be built leaving behind problems.”
1. Which word can be used to describe the maleos?| A．Endangered. | B．Adaptable. |

| B．The government will balance conservation and development. |
| C．There seems to be a tough way for the new capital to develop. |
| D．The government will concentrate on solving urban problems. |
8 . Tai chi, a traditional, slow-moving form of Chinese physical exercise, is known to increase flexibility and improve balance. New research has been conducted to determine whether tai chi has an influence on lowering blood pressure in people with prehypertension (高血压前期).
In the study, Chinese scientists put 342 adults with prehypertension into two groups. The average age of people taking part in the study was 49. About half the participants (参与者) took part in aerobic exercise, including jogging, climbing stairs and cycling. The other half was trained to practice tai chi. Both groups got hour-long exercises four times a week.
Nearly 22% of the people who practiced tai chi saw their blood pressure fall to be normal, compared with nearly 16% of people in the aerobic exercise group. And fewer patients in the tai chi group went on to develop high blood pressure than patients in the aerobic exercise group.
So what is it about tai chi that helps lower blood pressure? “The practice tends to get more of a response from the parasympathetic (副交感的) nervous system, which is the network of nerves that relaxes your body after periods of stress or danger,” says Ruth Taylor-Piliae, a professor at the University of Arizona’s College of Nursing.
“I think the beauty of tai chi is that you don’t have to have a special gym membership, you don’t have to have special clothing,” Taylor-Piliae says. “Once you learn tai chi, you can do it anytime and anyplace. And it does provide a calming and relaxing effect.”
Evidence suggests it can also help protect against cognitive fall and even improve memory. But you have to practice it continually to get the most benefit.

9 . Humans can make do with scarves, coats and gloves in cold weather. Some animals can hibernate (冬眠) for the winter. A new study finds that reptiles (爬行动物) and birds do something that is similar to hibernation, but a little different. In very cold weather, their body temperatures greatly drop into an energy-saving state in order to survive. The ability to thermoregulation (体温调节) for reptiles and birds is possible.
In Texas, where the city of Beaumont reached a low of 18 degrees Fahrenheit last month, it looked as if alligators (短吻鳄) had died of cold — yet alive in iced-over water. By ensuring their long noses stayed above the water line, the cold-blooded creatures were able to lower their body temperatures to survive the sudden short period of very cold weather. The process, in the case of cold-blooded animals like reptiles, is called brumation — it’s like a short state of hibernating. While in this state, reptiles become sleepy and they can go for a long time without eating or drinking. For example, alligators can be in brumation from just a few hours to months.
Like reptiles and mammals, birds can go into a state called torpor in order to save energy under very cold conditions. “Torpor is somewhere between a short sleep and hibernation,” said Justin Baldwin, a PhD candidate in biology at Washington University in St. Louis. Baldwin studied 29 species of hummingbirds living in Colombia. Researchers found that hummingbirds can enter into deep or shallow torpor, depending on several factors, including their size and weather conditions. In deep torpor, the birds are much more likely to be affected by disease. And what’s more, they would be easily harmed by their enemies.
Some bird lovers want to help the birds when they are in torpor. For example, the Bird Alliance of Oregon offers a few tips on how to keep the birds from danger.

10 . Here are the Disney movies recommended by Brandon Dammit for this weekend.
Fantasia 2000
Budget: $80 million
Score: 75%
I remember disliking Fantasia 2000 in theaters as a young child, but I have developed a much deeper appreciation for the fantastic music as an adult. Disney has employed advanced sound tools to produce a movie that was under-appreciated at its first appearance.
Pete’s Dragon
Budget: $65 million
Score: 60%
I love Disney as much as the younger generation. But it’s disappointing to see flavorless remakes like The Lion King and Beauty and the Beast harvest billions at the box office while more soulful remakes like Pete’s Dragon is largely ignored.
The Rescuers Down Under
Budget: $38 million
Score: 70%
I won’t lie to you, kind reader. The Rescuers Down Under is the only movie that I’ve never seen here and my honor won’t allow me to pretend otherwise. According to Disney, it’s about the world’s bravest mice, Bernard and Bianca, who race to Australia to save a boy and a rare golden eagle from a cruel hunter. So, you know, normal Disney stuff.
The Great Mouse Detective
Budget: $14 million
Score: 72%
Picture this: a young mouse named Olivia is committed to discovering the truth of her father’s disappearance in 1897 London, and she got the help from his friends, Dr. Dawson and Toby. It’s basically Disney’s Sherlock Holmes.
1. What does Brandon Dammit like about Fantasia 2000?| A．The plot. | B．The dialogue. | C．The music. | D．The actors. |
| A．The Lion King. | B．Pete’s Dragon. |
| C．Beauty and the Beast. | D．The Rescuers Down Under. |
