Everyone dreams. If you’ve ever tried to figure out the meaning of a strange dream, you’re not alone. Humans have been trying to make sense of dreams since recorded history. 1. Here are some of the findings.

2. People with great creativity are more likely to dream about unusual settings and about blocks in the natural world, such as a log or a rock they can’t get around.

You’ve got a heart problem. People who have frequent nightmares may be significantly more likely to suffer from an irregular heartbeat or chest pain. If you have those problems, it’s more difficult for you to breathe at night. 3.

You’re avoiding something. Do you dream about being followed by a stranger, a monster, or a giant tidal wave? This could indicate that you’re afraid to deal with something in your daily life. 4.

You’ll have a good result in a test. Students whose performance improved were those who had dreamed about the maze (迷宫) during the sleep. 5. This improves learning and problem-solving skills.

Despite the fact that technology has vastly expanded our understanding of dreaming, much of what occurs when we’re asleep remains as it has always been: a mystery.

If you ever have the desire to break out into song—in the shower, in the car, maybe at your neighbor's karaoke night—you should embrace it whole-heartedly. This ancient art not only makes you feel good, it can also improve your well-being, reduce your feelings of pain, and even extend your life.

Using your voice to sing, rather than simply carryout a conversation, offers unique benefits because singing affects our bodies. Also, studies link singing with a lower heart rate，decreased blood pressure and reduced stress according to Patricia Preston-Roberts, a music therapist. She uses song to help patients who suffer from a variety of problems.

Singing, particularly in a group, seems to benefit the elderly particularly well. As part of a three-year study examining how singing affects the health of those fifty-five and older, a Senior Singers Chorus was formed by the Levine School of Music in Washington, D. C. The seniors involved in the chorus, as well as seniors in two separate arts groups about writing and painting, showed significant health improvements compared to those in the control groups (控制组).Obviously, the arts groups reported thirty fewer doctors' visits, fewer eyesight problems, less depression, and less need for medication.

Even lead researcher Dr. Gene D. Cohen, director of the Center on Aging at George Washington University, was surprised at how big an effect the seniors' arts participation had on their health. Cohen said, “The average age of all the subjects was eighty. This is higher than life expectancy. So, if an effect were to be achieved, one would ordinarily expect to see less decline (下降) compared to the control group. The fact that there was so much improvement in many areas was the surprising factor." The seniors also noticed health improvements and they reported feeling better both in daily life and while singing.

The part of the brain that works with speech is different from the part that processes music. “People seem to enjoy doing something jointly with other people. There are a lot of facts that being socially involved is good for people with dementia (老年痴呆).”Ballard said.

The arts are showing up as a treatment tool in hospitals across the country. If you are thinking of volunteering, singing at a hospital may be a good choice—not only for the patients, but also for yourself.

A. expresses a desire for singing

As scientists in the Netherlands tried to figure out how to build a super flying robot, they learned from one of nature s flyers: the humble fruit fly(果蝇).And by building this robot, they’ve gained new insights into how the fly carries out one of its dangerous tasks.

The robot is called the DelFly Nimble Its wingspan(冀展)is about a foot wide. It has four wings that can beat at 17 times per second, which appear very delicate because they’re made of the same material as space blankets.

In the previous designs. they always had a tail, like a traditional airplane tail, said the robots main designer Matej Karasek. He’s based at the Micro Air Vehicle Laboratory at Delft University of Technology in the Netherlands, and he and his colleagues published their findings on Thursday in Science

“In the previous generations", he said, "flapping wings drove the robot forward while the tail helped to guide and stabilize it. But now the DelFly Nimble is completely controlled by the wings. The challenge then was actually combine the control into the wing movement, and that’s what we achieved, Karasek said

In the latest generation. the wings can each move individually or rotate(旋转)around the body of the robot in order to maximize the machine s agility(灵活 ) The robot can remain in one place in the air for about five minutes on a full battery or fly for more than a kilometer"， Karasek said, "And because the scientists are controlling all the movements, they can use the robot to learn more about how fruit flies actually carry out their dangerous tasks, which has caught the attention of biologists.”

1.Where did scientists get the creative idea of the flying robot?

A. From a fruit fly　　 B. From the birds wings

C. From some fruit　　 D. From an airplane

2.What does the underlined word "it" in Paragraph 4 probably refer to?

A. A full battery.　　 B. A flapping wing.

Have you ever dreamed of meeting top scientists in person? If so, what would you want to ask them? For Tan Fanglin, a 15-year-old girl from No.2 High School of East China Normal University in Shanghai, her dream of meeting top scientists has already come true.

In October, she attended the World Laureates Forum(论坛)for a second time. Tan was by far the youngest participant among the scientists invited to be at the meeting of the world's sharpest minds. Her discovery about the relationship between the Fibonacci sequence(菲波那契数列)and Bézout numbers has won her many prizes in youth innovation competitions. This finding has been praised by the famous Canadian mathematician, Professor Rankin. According to Guangming Daily, Rankin has been studying the same theme for five years but with no conclusions.

From a very young age, Tan has always been fascinated by mathematics. This is largely because of the influence of her father, who teaches mathematics in University. But she had not participated in any Mathematics Olympiad exams before. According to Xu Jun, Tan's head teacher from her middle and high school, she doesn't take after-school classes or too many extra exercises either. Her mastering of Further Mathematics and her good grades in school are thanks to the right study method.

Attending this forum enabled Tan to get more inspiration from top scientists. She asked Professor Miesenbock, the 2019 Warren Alpert Foundation Prize winner, what he considered were the best personal qualities for conducting scientific research. Miesenbock encouraged her not to lose her passion and love for what she does. He stressed that people all knew that even Thomas Edison went through hundreds of unsuccessful attempts before finally inventing the light bulb. Tan has met many barriers in her research and often feels upset. The words made Tan feel inspired. "I will keep my curiosity and interests in mathematics and overcome any obstacles(障碍)in my research," she told Chinese Business View.

When was the last time you relied on an old-fashioned map to figure out the route to an unfamiliar place? For many, the GPS has revolutionized navigation, making a paper map almost obsolete? So how has this piece of technology developed over its 26 years of existence? On February 14,1989,the first satellite in the US Global Positioning System was sent into space from Cape Canaveral, beginning the start of one of the wonders of the modern world.

GPS stands for Global Positioning System, which is made of a network of around 30 satellites that move around the earth. The system uses a process called trilateration to find out one’s position. By measuring the time it takes for the signal to reach one satellite, the GPS can determine your distance from the satellite, creating a sphere(范围) of possible locations. Measuring your distance from at least three satellites will narrow your location to the place where the three spheres cross one another, to the accuracy(精确) of about less than 1 meter!

The GPS was first invented during the Cold War by the United States Department of Defense. In 1960, the first system, which was made of just five satellites, was put into place. It was initially created for strictly military(军事的) use; however, in 1983, as a result of faulty navigation technology, a Korean passenger plane mistakenly flew into USSR territory(苏联领土) and was shot down. In order to prevent such bad events, American President Ronald Reagan allowed civilian(民用的) use of the GPS.

Over the next ten years, the system’s accuracy improved as the network was increased to 24 satellites. And during the first Persian Gulf War, the new GPS was finally used by the military. Now scientists use the technology to track animals to better understand their movement and behavior. Parents who may be worried about their children can also use GPS technology to track them.

1.The underlined word “obsolete” in Paragraph 1 can best be replaced by “　　　 ”.

A. priceless　　 B. unusual

C. perfect　　 D. useless

2.The second paragraph is mainly about 　　　 .

A. how the GPS works　　 B. the history of the GPS

C. the applications of the GPS　　 D. some problems with the GPS

3.According to the text, the GPS　　　 .

A. has a history of over 100 years

B. became popular during the Cold War

C. relies on the satellites circling the earth

D. was available first during space exploration

4.What does the author think of the GPS?

A. It is not always reliable

B. It has a lot of uses in many fields

C. It makes our life more peaceful

D. It will soon go out of fashion

The expression “Go for it!” is a way of encouraging someone to try something.

“Go for it!” means you should not worry about failure or be too careful. You should take a chance, be brave, and act firmly.

The conservative choice is to kick the ball and accept temporary defeat in order to gain a good position for your team the next time it gets the ball. The more exciting choice, however, is to try a fourth and final time to gain the remaining yards needed.

In the nineteen eighties, people began using this expression in many kinds of situations to encourage someone to act bravely.
