In 1992, Teen Talk Barbie was released with the controversial voice fragment, “Math class is hard.” While the toy's release met with strong public reaction, this underlying assumption persists, spreading the myth that women do not thrive in science, technology, engineering and mathematic (STEM) fields due to biological inadequacies in math aptitude. However, in 2019 Jessica Cantlon at Carnegie Mellon University led a research team that comprehensively examined the brain development of young boys and girls and found no gender difference in brain function or math ability.
Cantlon and her team conducted the first neuroimaging study to evaluate biological gender differences in math aptitude of young children. Her team used functional MRI（核磁共振）to measure the brain activity in 104 young children (3-to-10-year-old; 55 girls) while watching an educational video covering early math topics, like counting and addition. The researchers compared scans from the boys and girls to evaluate brain similarity. In addition, the team examined brain maturity by comparing the children's scans to those taken from a group of adults (63 adults; 25 women) who watched the same math videos.
After numerous statistical comparisons, Cantlon and her team found no difference in the brain development of girls and boys. In addition, the researchers found no difference in how boys and girls processed math skills and were equally engaged while watching the educational videos. Finally, boys' and girls' brain maturity were statistically equivalent when compared to either men or women in the adult group.
Cantlon said she thinks society and culture are likely steering girls and young women away from math and STEM fields, as previous studies show that families spend more time with young boys in play that involves spatial cognition（空间认知）. “Typical socialization can make worse small differences between boys and girls that can snowball into how we treat them in science and math,” Cantlon said. “We need to be aware of these origins to ensure we aren't the ones causing the gender inequities.”
However, this project is focused on early childhood development using a limited set of math tasks. Cantlon wants to continue this work using a broader scope of math skills, such as spatial processing and memory, and follow the children over many years.
1.What can we infer about the toy’s release?
A.It has raised a storm of applause.
B.Girls perform no worse than boys in math.
C.Math is a subject difficult to every one of us.
D.Women are born with insufficient math abilities.
2.What can we learn from the study conducted by Cantlon?
A.Boys process math skills more quickly than girls.
B.Boys and girls have similar brain in math abilities.
C.Boys and girls have similar interest in math.
D.Adults have better brain than children in math.
3.What will Cantlon most likely agree with?
A.Parents should lengthen the time spent with girls.
B.Society is causing a greater gender difference in math abilities.
C.Culture plays a leading role in children’s brain development.
D.We should cultivate boys’ and girls’ math abilities equally.
4.How will Cantlon further her research?
A.By using a wider range of math skills.
B.By involving a broader scope of subjects.
C.By increasing the complexity of math tasks.
D.By following the children until their adulthood.

There had been worrying news about Justice League in the months before its release, with a lot of reshoots of scenes, a new director being brought in to finish the film after Zack Snyder's loss of his daughter (Zack Snyder was the original director). And, of course, there had been a lot of negative talk about Ben Affleck's acting skills in the role of Batman.
Some people are saying that Justice League is another big disappointment, because it could have been wonderful and instead fails to really entertain. Others say that Warner Bros. has finally got it right and that the future for Justice League looks bright.
My opinion lies somewhere in the middle. The film was by no means a disappointment: it was exciting and funny and brought a lot of fun. There was something special about watching the heroes from your childhood brought to life on the big screen and maybe that was affecting my opinion.
However, I will say that a lot of work needs to be done if the producer wants to produce better sequels (续集). Although the film was good, it was obvious which scenes had been reshot and how the characters had been changed. I also have to mention the special effects created in several scenes. These are the ones that you don't expect to see in a film with such a big budget.
Another point to add is that it is good to see the producer making Superman slightly a brighter character and adding some jokes to the plot to keep things fun. But the producer must be careful not to make the mistake that another film producer - here, not mentioning its name - is coming very close to doing: turning all of the films into bright and colorful shows and losing a lot of serious and seriously good stories.
So, Justice League is not a great film but it is certainly not a terrible one. A lot of work is still to be done.
1.Before the release of Justice League, many people showed .
A. their pity for the director, Zack Snyder
B. their concern about the film's quality
C. their higher expectation of the new director
D. their support for the actor, Ben Affleck
2.According to the author, what's special about Justice League?
A. It advocates social justice. B. It brings lots of fun to audience.
C. It has some brave heroes. D. It brings back childhood memories.
3.What's Paragraph 4 mainly written to show?
A. The author's views on the film's weaknesses.
B. The author's advice to the film's director.
C. The author's love for the film.
D. The author's expectation of the film's sequels.
4.The mention of another film producer is to .
A. stress the importance of fun in a film
B. show Justice League's lack of a serious plot
C. serve as a warning to Justice League's producer
D. set an example for Justice League's producer
5.The passage is possibly taken from .
A. a travel brochure B. an entertainment magazine
C. a news report D. an advertisement

请阅读下面一篇短文，并按要求用英语写一篇150词左右的文章。
As bike-sharing booms in China, a guideline was released by the government to promote a new form of the sharing economy - this time involving vehicles.
Car-sharing, which provides an alternative for people to travel in cities, will be the new innovation in a service model. The released guideline focuses on legal status, insurance and regular maintenance of cars before they join sharing services. It encourages the development of car-sharing, which is expected to reduce the liking to individually buy vehicles and ease traffic congestion amid a surge in recent years of private-car ownership.
“However, there is a long way to before the purpose of the guideline comes true,” said Xia Xueluan, a professor of sociology. “First, a car costs at least 100.000 yuan, almost 500 times that for a shared bicycle. Besides, shared cars also take the same spaces as other private cars, so parking will be another problem.”
“Meanwhile, traditional car rental companies are competing with the emerging car-sharing business. It’s estimated the charges will be almost the same for both forms of cars rentals,” Xia said. “How to survive fierce competition will remain a challenge for car-sharing providers,” he added.

I was doing some Christmas shopping in a toy store and decided to look at Barbie dolls for my nieces. A nicely dressed little girl was excitedly looking through the Barbie dolls as well. As she was looking, a little boy came to the Pokemon toys. He was dressed neatly, but his clothes were obviously old. He was with his father as well, and kept picking up the Pokemon video toys. Each time he picked one up and looked at his father, his father shook his head and said, “No.”
The little girl had chosen her Barbie. However, she stopped and was watching them. Rather dejectedly, the boy had to give up the Pokemon toys and choose something else. The little girl put her Barbie back on the shelf, and ran over to the Pokemon toys. She excitedly picked up one and raced towards the checkout. I picked up my purchases and got in line behind them. Then, much to the little girl’s delight, the little boy and his father got in line behind me. After the toy was paid for and bagged, the little girl handed it back to the cashier (收银员) and whispered something in her ear. The casher smiled and put the package under the counter.
I paid for my purchases and was rearranging things when the little boy came up to the cashier. The cashier checked his purchases and said, “Congratulations, you are my hundredth customer today, and you win a prize!” With that, she handed the little boy the Pokemon toys, and he could only stare in surprise. It was exactly what he had wanted!
The little girl and her father had been standing at the doorway during all of this. Then they walked out. As I walked back to my car, I heard the father ask his daughter why she had done that. I’ll never forget what she said to him. “Daddy, didn’t Grandparents want me to buy something that would make me happy?” He said, “Of course they did, honey.” To which the little girl replied, “Well, I just did!”
I feel very shocked to have witnessed the true spirit of Christmas in that toy store, in the form of a little girl who understands more about the meaning of this festival than most adults I know.
1.The underlined word “dejectedly” in the second paragraph probably means _____.
A．delightedly B．disappointedly C．excitedly D．unexpectedly

B．Fortunately, he was the hundredth customer and won the Poknemon toys.
C．The cashier felt sympathy for the little boy and gave him the Poknemon toys.
D．The little girl bought the Poknemon toys for him.
3.What did the little girl mean when saying “Daddy, didn’t Grandparents want me to buy something that would make me happy?”
A．Her Grandparents wanted her to be happy.
B．Making the little boy happy made her happy.
C．The Poknemon toys made her happy.
D．Her Grandparents hoped that she could help others.
4.Which of the following statements is NOT true according to the passage?
A．the story happened before Christmas.
B．The little boy had not enough money to buy the Poknemon toys.

It was the last time Susan Butcher ran the Iditarod Trail Sled Dog Race in 1992. An hour into the race, Susan and her sled dog team sped down a hill and crashed into a fallen tree. Although hurt, Susan continued the difficult race.
The Iditarod Race started in 1925 when a doctor in Nome, Alaska was desperately in need of medicine to stop the spread of a deadly disease. Only a hospital had what he needed, but it was 700 mile-away! In January, it was too dangerous to send a boat and too stormy for his tiny airplane. The only hope was to use several sled dog teams following a trail, called the Iditarod Trail. They passed the medicine from one sled team to another. Wind and snow did not stop the men and their dogs. The medicine was delivered in record time. The race follows the route of the famous medicine run. Over 1,000 miles long, it is considered the toughest race in the world.
Susan Butcher was born in Cambridge, Massachusetts. In her teens Susan was given a Siberian husky dog and became very interested in huskies as sled dogs. After reading about the Iditarod Race, Susan moved to Alaska. She got several jobs to earn money to buy herself a sled and a team of huskies. After years of hard work and training, Susan achieved her dream of racing on the Iditarod Trail.
In 1978, at the age of 24, Susan entered the race for the first time and became the first woman to finish in the top 20. In 1982 she came in second. In 1984 she was leading her team across a frozen waterway when they fell into the water. Her lead dog managed to pull Susan and the other dogs out of danger. Remarkably, she came in second.
In her fourth race, in 1985,a starving moose(驼鹿) attacked her dogs, killing two and injuring eleven. Susan had to leave the race. In 1986 Susan joined the race again. This time, she won. She won again in 1987. In 1988 she became the first person ever to win three Iditarod races in a row. Unbelievably, Susan won for the fourth time in 1990.

In 1992, I had just launched a new business called Video News International.
It was the world's first video journalist network. The idea was to cover news and sell the service to news organizations.
One day, a young intern (实习生) who was working for us named Anthony Lappe pulled me aside.
"There is something you have to see," he told me. "Comcast is doing this really cool thing."
"What?"
"The Internet," he said. "It's going to be really big."
Anthony later introduced me to the head of the Internet project.
"We are looking for content to put on our network here," the guy said to me.
Well, I said I had lots of content to offer.
The guy's eyes lit up. "Cool," he said. "We would like to put it on our network."
Well, I was always looking for new clients.
"What are you going to pay?" I asked.
He said that they could not pay anything for the content, but they would set up a URL for me.
"What's that?" I asked.
"It's kind of like your address on the web."
"What would I do with this URL thing?"
"Well, it could be your business."
"I don't see how it is a business, and there's not even any advertising," I cleverly replied.
"Not yet," he said. "But one day there might be."
I thought about it for two seconds.
"Naah..." I said. "I've got bigger fish to fry. I've got to be going now. Maybe we can cooperate next time."
And I walked out.
Idiot!
Well, that Internet thing turned out to be so much bigger than I had thought. I wish I had never made such a mistake. Sorry Anthony. You were right.
1.The head of the Internet project expected the author to _______.
