4 . Until recently, gravitational waves could have been the stuff of Einstein’s imagination. Before they were detected, these waves in space time existed only in the physicist’s general theory of relativity, as far as scientists knew. Now, researchers are on the hunt for more ways to detect the waves. “The study of gravitational waves is booming,” says astrophysicist Karan Jani of Vanderbilt University in Nashville. “This is just remarkable. No field I can think of in fundamental physics has seen progress this fast.”
Just as light comes in a variety of wavelengths, so do gravitational waves. Different wave lengths point to different types of origins of the universe and require different kinds of detectors. Gravitational waves with wavelengths of a few thousand kilometers—like those detected by the United States, Italy and Japan—come mostly from pairs of black holes 10 or so times the mass of the sun, or from collisions of dense cosmic blocks called neutron stars (中子星). These detectors could also spot waves from certain types of exploding stars and rapidly moving neutron stars.
In contrast, huge waves that span light-years are thought to be created by orbiting pairs of bigger black holes with masses billions of times that of the sun. In June, scientists reported the first strong evidence of these types of waves by turning the entire galaxy (星系) into a detector, watching how the waves make slight changes to the timing of regular blinks from neutron stars throughout the Milky Way.
Physicists now hope to dive into a vast, cosmic ocean of gravitational waves of all sorts of sizes. These waves could reveal new details about the secret lives of exotic objects such as black holes and unknown parts of the universe.
Physicist Jason Hogan of Stanford University thinks there are still a lot of gaps in the coverage of wavelengths. “But it makes sense to cover all the bases. Who knows what else we may find?” he says. The search for capturing the full complement of the universe’s gravitational waves exactly could take observatories out into the moon, to the atomic area and elsewhere.

The Charm (魅力) of Schoolyard
In the charm of school life, where classrooms are seats of knowledge and the schoolyard becomes source of memory, there are a fund of stories mixed with humor, warmth, and teacher-student relationships.
Mr. Smith was a country teacher, but not an ordinary one; he was a storyteller, a mentor (人生导师) , and a friend to all his students. His classroom was a world of its own, full of colorful characters and brilliant ideas. One day, during the noon break, a student named Alice noticed a wandering kitten padding (潜行) through the familiar grounds where many schoolyard tales were born. Alice took her to Mr. Smith, who had magical Tricks for handling even the smallest things. With Mr. Smitt’s permission, Alice and her classmates built a shelter for the kitten in a corner of the campus.
The days turned into weeks, and the kitten grew under the tender care of Mr. Smith and his students. Once in a while, she became a temporary resident of the classroom, much to the delight of the whole class. They named her “Schoolyard”, a name that generalized the spirit of their school days.
As the year progressed, Schoolyard became not just a kitten, but a tie connecting each of them and a thread of continuity in their lives. She played on desks, slept in chairs, and hid in folders, thus becoming an unofficial mascot (吉祥物) of the classroom. The students found comfort in her presence, and Mr. Smith, joy in watching them grow through her company.
As graduation neared, Mr. Smith gathered his students for one last lesson. He told them that they would soon be exploring new horizons. He reminded them that life was full of unforeseeable twists and tums along with unexpected potentials, just like the appearance of a kitten in their schoolyard. At the moment, the students were greatly touched and deep down there arose a strong love for those memorable warmth and hearty laughter of their school days.
Thereafter, Mr. Smith and the students agreed to meet here once again in ten years.

8 . British visitor Joel Bennett expressed his appreciation to a restaurant owner, a lady in her 60s, for a good meal during his first trip in South Korea. Bennett, at age 23, said “gomawo” to the owner, which means “thanks” in English.
In South Korean culture, as a person several decades younger than the owner, Bennett was expected to have used the honorific forms of the language. Korean is said to have one of the most complicated linguistic systems in the world.
To fully understand this, you need to learn the lasting impact of the ancient culture of South Korea. Its ancient social order is centered on harmony, which is often achieved by treating the elderly with respect and looking after the young with kindness.
While age plays a big part in determining speech style, it’s not a hard and fast rule.
A.He then thought he was polite to say so. |
B.Nowadays, the Korean wave has swept many countries. |
C.And this tradition has guided the country for over 500 years. |
D.It is no surprise to be asked to reveal your age in South Korea. |
E.A funny fact is that it’s difficult not only for guests but also hosts. |

10 . Many people, especially the elderly, suffer from abnormal sleep. In particular, the deep sleep phases become shorter and shallower with age.
Researchers have shown that the brain waves characterizing deep sleep, so-called slow waves, can be improved by playing precisely timed sounds through earphones while sleeping. While this works well in the laboratory under controlled conditions, there has been no at-home solution that can be used for a time longer than just one night.
As part of the SleepLoop project, researchers have developed a mobile system that can be used at home and aims to promote deep sleep through auditory(听觉的) brain stimulation.
The SleepLoop system consists of a headband that is put on at bedtime and worn throughout the night. This headband contains electrodes(电极) and a microchip that can constantly measure the brain activity of the sleeping person. As soon as the sleeping person shows slow waves in the brain activity, the system will set off a short auditory signal. This helps synchronize(使……同步) the neuronal cells and enhance the slow waves. What makes the solution unique is that the sleeping person is not consciously aware of this sound during deep sleep.
It’s the first time that the researchers, led by Caroline Lustenberger, have conducted a clinical study with this device. The study involved equipping participants, between 60 and 80 years old, with the SleepLoop system, which they were required to operate in their own homes. The system is designed to function independently even for users with little technical experience. “This worked very well. We had surprisingly little data loss and the participants rated the device as user-friendly,” says Lustenberger.
The participants wore the device every night for a total of four weeks. The results showed it was indeed possible to enhance the slow waves through auditory signals during deep sleep in most participants. However, individual differences were considerable, which can be used to better predict how a given individual will respond to the auditory stimulus. The company ToSoo AG is currently working on that so that it can be competitive once it comes onto the clinical market. It’s already clear that it’ll not be freely available, but only via a doctor’s prescription. “Use of the device must be medically indicated,” a researcher says.
