When    1    (talk) about the two genders (性别), people often say that men are from Mars and women are from Venus. It is true     2    men and women are different in many ways.

However, many of these differences in character can     3     (explain) by differences between the brains of men and women. For example, a study     4     (lead) by a British psychologist in 2012 found men's brains are, on average, 10 percent bigger than women's brains. But Lise Eliot, a professor at    5    Medical School of Chicago University, doesn't think the brain differences can explain personal features. She found that the brain differences mean nothing.

So, if it's not in the brain, what is it that makes males and females behave    6     (different)? The answer may lie in socialization. In the past, many gender     7     (study) ignored a person's social background and upbringing. Take former Harvard University president for example. According to a 1970 research that showed men     8    (beat) women 13-to-one, he thought men were     9     (good) at science subjects.     10    , another study found that if females were given more opportunities to study science subjects, the ratio would drop to three-to-one.

Imagine cozying up in your bed after a long day. Yous scroll through your favorite social media apps for what feels like ten minutes, but then you realize hours have passed. It’s now 2:30 am, and you know you need to get some sleep to wake up     1     (refresh) for work. But you just can’t get yourself to stop scrolling and turn in for the night. You promise     2     just five more minutes - then it’s 3:00 am.

You wake up tired the next morning and go to work groggy but do the same thing again that night. You know you need the rest,     3     you still stay up and sacrifice sleep to scroll aimlessly on your smartphone.

If you can relate to this scenario, you’re not alone. Now called “revenge bedtime procrastination,” the Sleep Foundation describes this phenomenon as the tendency “to sacrifice sleep for leisure time that is driven by a daily schedule     4     (lack) in free time.”

People who spend most of their waking hours working     5     (experience) a severe lack of “me time” in which they can be free of responsibilities. Nowadays, some people feel guilty even for resting, so there is a strong craving for uninterrupted personal time.

Daphne Lee, the journalist     6     viral tweet popularized the term, describes revenge bedtime procrastination as an attempt to regain control of our lives. If you are spending most of the day working for someone else, following someone else’s orders, and disciplining yourself into doing what you’re “supposed” to do, it is only natural that you     7     desire freedom - at least for the few quiet hours around midnight.

Some people find that sense of control by doing things often thought of as lazy or     8     waste of time - for instance, scrolling through social media or binge-watching TV shows. By indulging in these activities in the wee hours of the night when the world is asleep, people get a sense of “revenge” and control over     9     they spend their time.

Revenge bedtime procrastination is experienced differently by various groups,     10     being motivated by the same reasons. Parents of young children spend most of their day trying to balance work and childcare, so there is a powerful desire to spend some time alone, free of all obligations. For many parents, this is only possible at night when work hours are over and the kids are asleep.

In the future, everybody will have a Harry Potter invisibility cloak in the closet, said Chu Junhao,     1     academician of the Chinese Academy of Sciences in Shanghai on Saturday.

At the Super Science Night     2     (hold) by Bilibili, China’s major video-sharing platform, Chu showed     3     invisibility can be achieved with special technologies and materials. He asked two staff members to hold a panel in front of him.     4    (initial) , the lower part of his body was visible through the panel. After rotating the panel 90 degrees, his lower half disappeared,     5     the stage behind him could still be clearly seen.

The magic was realized by a lenticular (透镜的) grating composed     6     rows of tiny cylindrical (圆柱形的) convex (凸面的) lenses, and each vertical cylindrical convex lens can shrink and thin objects parallel to it, so that light can be refracted (折射的) , according to Chu. When a row of cylindrical convex lenses forms a grating, several images     7    are too small to be noticed by the eye     8    (produce) achieving an invisibility effect. Chu also showed several other ways     9    (invisible) , such as using two substances with similar refractive indices and a plane mirror to create reflection imaging.

“Invisibility in science fiction will become    10    (real) as invisibility technology and material develop,” he said. “More invisibility equipment will change our life, such as invisible rooms that can provide better privacy and invisible hearing-aids.”

China’s deep-sea manned submersible (潜水器) “Fendouzhe” went down to 10,909 meters in the Mariana Trench on Tuesday.

Three divers sent back a group photo with each person     1     (carry) a food plate in their hand after four hours of the task. That spot is known as the Challenger Deep, with the water pressure of 110 KPa, equal     2     the pressure of 2,000 African elephants.

The submersible uses titanium (钛) a perfect material     3     allows the submersible not only to bear water pressure at 10,000 meters,     4     also to reduce self mass (质量) and expand inside space.     5     (power) by a lithium (锂) battery, “Fendouzhe” can unload equipment onboard and pick up samples from the     6     (surround) environment with its flexible robotic arms.

China’s first deep-sea manned submersible. “Jiaolong”, went 7,062 meters down into the Mariana Trench in 2012. “ShenhaiYongshi” is the second manned submersible that can reach a(n)     7     (deep) of 4, 500 meters. Ninety-five percent of technology components applied on the second generation submersible are made in China. The “Fendouzhe” project     8     (launch) back in 2016, with some of the best submersible engineers in China     9     (involve). It is     10     (smart) for carrying three researchers to more than 10,000 meters deep than “ShenhaiYongshi”.

GoPro, Young Man

In October 2012, when the Austrian stuntman（特技替身男演员）Felix Baumgartner jumped from a balloon at nearly 128,000 feet and exceeded the speed of sound during a free fall, five little GoPro cameras were strapped to his suit to record high-definition views of his heroics. At around the same time, GoPro became the best-selling video camera in the United States, and its inventor and chief promoter, a Northern California surfer     1     (name) Nicholas Woodman, became a billionaire. Woodman is now 39 but seems younger. His success is due in part to his authenticity - he is a genuine member of the extreme-sports crowd, given to shouting and exclaiming "Magnificent!" without irony. But he is also an unusually focused businessman.

Woodman started with the idea of     2     (invent) a wrist strap to which surfers could attach a camera to show themselves in action. He soon realized that     3     lack of suitable devices in the market-place, he had to invent the camera too -- something inexpensive, waterproof, mountable every which way, and     4     (provide) an ultra-wide-angle view. In a world covered with water in polished videos of professional surfers, he sympathized with the urge that ordinary surfers save to look like that, too. He called the camera the Hero, and began to sell it to surf shops in 2004. It took off right away, with sales that grew from about 1,500 units the first years to at least three million annually today,     5     it wasn't just the surfing culture that he tapped into. It turned out that all sorts of people     6     (do) all sorts of things wanted to mount a camera to film themselves and their activities. The camera also caught on with scientists, soldiers, athletic coaches, journalists, and surgeons too. But it's the amateurs     7     count the most. Woodman thought he     8     (sell) mainly to fellow surfers, but as Facebook, Twitter, and Instagram have shown, the interest of people in     9     is boundless. Woodman's market position turned out to be humanity. Now his company is going public. No wonder he says he     10     (fuel).
