2 . The emergence of black holes undoubtedly marks the beginning of a revolution. Black holes have many peculiar properties, such as the alteration of space and time, the radiation of gravitational waves and so on. Scientists are still trying to study the properties and evolution of black holes in order to better understand the origin and evolution of the universe.

Recently, a team of astronomers may have found a solo-wandering black hole using a strange trick of gravity called microlensing (微透镜效应), but the results still have to be confirmed.

Sometimes it’s tough being an astronomer. Nature likes to hide the most interesting things from easy observation. Take, for example, black holes. Except for the strange quantum (量子) phenomenon of Hawking radiation, black holes are completely black. They don’t emit a single bit of radiation – they only absorb, hence their name.

To date, the only way astronomers have been able to spot black holes is through their influence on their environments. For example, if an orbiting star gets a little too close, the black hole can absorb the gas from that star, causing it to heat up as it falls. We can watch as stars dance around the giant black hole at the center of the Milky Way.

Even the famed pictures of the black holes in the center of the Milky Way and the M87 galaxy(星系) aren’t photographs of the black holes themselves. Instead, they are radio images of everything around them.

But surely not all black holes have other light-emitting objects around them to help us find them. To find these wanderers, astronomers have tried their luck with microlensing. We know that heavy objects can bend the path of light around them. This is a prediction of Einstein’s general theory of relativity, and the slight bending of starlight around our own sun was one of the first successful tests of the theory.

Microlensing is pretty much what the name suggests. When astronomers get extremely lucky, a wandering black hole and pass between us and a random distant star. The light from that star bends around the black hole because of its gravity, and from our point of view, the star will appear to temporarily flare in brightness.

And when I say “extremely lucky” I mean it. Despite trying this technique for over a decade, it is only now that astronomers have found a candidate black hole through microlensing. Two teams used the same data, a microlensing event recorded from both the OGLE (Optical Gravitational Lensing Experiment) telescope in Chile and the MOA (Microlensing Observations in Astrophysics) telescope in New Zealand. One team found that the mass was somewhere around seven times the mass of the sun – definitely black hole territory. But the other team estimated a much smaller mass, around 2-4 times the mass of the Sun. If the true mass of the object is at the lower end of that spectrum (光谱), then the wanderer is probably not a black hole.

3 . Many of the world’s islands were previously unexplored places, but over time, people have come to these places with far-reaching effects, including deforestation, over-hunting and the introduction of invasive species. _______, most of the bird species disappeared.

While the death of many birds since the 1500s has been _______, our knowledge of the fate of species before this relies on fossils (化石), and these records are limited because birds’ lightweight bones are _______ over time. This conceals the true _______ of global extinctions.

Researchers now believe 1,430 bird species — almost 12 per cent — have died out over modern human history since around 130,000 years ago, with the vast majority of them becoming extinct directly or indirectly _______ human activity.

The study, led by the UK Centre for Ecology & Hydrology (UKCEH) and published in Nature Communications, used statistical modelling to _______ the undiscovered bird extinctions.

Lead author Dr Rob Cooke, an ecological modeler at UKCEH, says:“Our study demonstrates there has been a far higher _______ impact on diversity than previously recognized. Humans quickly destroyed bird populations through habitat loss, over-exploitation, and the introduction of rats, pigs, and dogs, which attacked the birds’ nests, and _______ with birds for food. We show that many species became extinct before written records and left no _______, lost from history.”

Dr Søren Faurby of the University of Gothenburg, a co-author of the study, adds: “These historic extinctions have had a major impact on the current biodiversity crisis. The world may not only have lost many fascinating birds but also their varied ________ roles, which are likely to have included key functions such as pollination (授粉). This will have had knock-on effects on ecosystems, so, ________ bird extinctions, we will have lost a lot of plants and animals that ________ these species for survival.”

Observations and fossils show 640 bird species have been driven extinct — 90 per cent of these on islands ________ by people. These ________ from the iconic (标志性的) Dodo of Mauritius to the Great Auk of the North Atlantic to the lesser-known Saint Helena Giant Hoopoe. But the researchers estimate there have been further 790 unknown extinctions, meaning a total of 1,430 lost species — leaving just under 11,000 today. Therefore, from the perspective of protecting species ________, the protection of birds is an urgent issue for mankind.

4 . Global surface temperatures last month were 2.25 degrees warmer than the 20th century average of 60.1 degrees, breaking previous records, from August 2016, by more than half a degree, according to NOAA researchers. “That to me is a really huge _______ from one record to the next,” said Ellen Bartow, a physical scientist with NOAA’S National Centers for Environmental Information.

The report _______ what millions of people have experienced in recent months, including record-breaking heatwaves that have touched almost every corner of the globe. Asia, Africa, North America and South America had their warmest August on record, as did the Arctic, Europe and Oceania — a region that _______ Australia - had their second-warmest August on record, the report said.

It wasn’t just the land that _______ : August set a record for the highest monthly sea surface temperature abnormally—1.85 degrees above average.

How to Stay Healthy in Autumn

In recent days, the weather in most regions is no longer hot, and people can relax and enjoy the cool autumn. However, there is a big gap in temperature in the morning and evening, and the air is also drier. All of these factors can lead to dry mouth and nose, sore throat, dry cough, dry hair loss and other symptoms. People are more likely to get sick during the seasonal change from summer through autumn. So, here are some tips to keep you healthy and comfortable into the winter months.

Do eat watery food. According to traditional Chinese medicine, autumn corresponds to the lungs of the human body.Pay attention to wet lungs in dry weather.The most convenient and easy way to protect lungs in autumn is to drink more water. In addition, you can adopt the diet therapy of traditional Chinese medicine, eating some watery food, like pear and duck meat.

Do have easily digested food. People’s spleen (牌) and stomach functions are weakened because of the raw and cold food they had during the long, hot summer. So in autumn, you should give your spleen and stomach a rest. For example,you can choose some nutritious food that is easy to digest to eat, such as fish and red bean.

Be sure to take vitamin supplements. Vitamins play an important role in the body’s immune system. The number and vitality of immune cells are related to vitamins when the body resists foreign invasion. It is recommended that you eat plenty of fresh vegetables and fruits rich in vitamin C, such as kiwi and oranges.

Sleep is an important means for people to restore their physical strength, ensure their health and enhance their immunity. In autumn, it is suggested that you go to bed at 9 pm, or try to fall asleep before 11 o’clock. If you sleep at this time, it is great for your body and you can get a good quality of sleep.

Zaha Hadid

Born in Iraq in 1950, Zaha Hadid was the first woman to win the Pritzker prize, the field’s highest honor. But for years, she had to fight to prove that her designs could even be built. She was a pioneer in Deconstructivism: Designing buildings that looked unstable, jagged, or frozen in mid-explosion. She gained a reputation for her gorgeous, fantastical designs—painted by hand. But her ideas looked impossible to build, so they remained on paper.

Then, in 1983, she won a big competition to design a club in the hills of Hong Kong. Hadid proposed carving chunks out of the mountainside, which she called a “man-made geology.” The project was eventually canceled, but the world of architecture then knew her name.

Still, it took another decade before one of her concepts actually got built: A fire station in Germany with no right angles; looking like it could take flight. It was a great success—quickly becoming a prime example of Deconstructivist architecture.

Around the same time, she won an international competition to design an opera house in Wales, but it was overruled by local politicians, and the funding was pulled. Later, Hadid said it was resistance and prejudice that killed the project.

But she kept winning competitions, building momentum—and finally, buildings! By the early 2000s, she was an architecture superstar. She still drew by hand, but adopted new computer technology to model her designs. The software made even wilder shapes possible—including the curves that became her signature. A Hadid design was no longer crazy or impossible—it was simply a Hadid.

Sadly, she died of a heart attack in 2016. By then she had built hundreds of buildings, with many more in progress. And she had proved she could build nearly anything she could imagine.

7 . Of Special Interest to Freshman

Freshman Seminars are small classes just for freshmen, with some of York’s most distinguished faculty members. Some seminars provide an introduction to a particular field of study; others take an interdisciplinary (跨学科的) approach to a variety of topics. All seminars provided a friendly environment for developing relationships with faculty members and peers.	STARS (Science, Technology, and Research Scholars) provides undergraduates of every year with an opportunity to combine research, course-based study, and development of mentorship skills. The program offers research opportunities and support to students historically underrepresented in the fields of natural science and quantitative reasoning, such as racial and ethnic minorities, women, and the physically challenged. More than 100 students each year participate in STARS, during the academic year or over the summer months.
Directed Studies is a selective freshman interdisciplinary program focusing on Western civilization that includes three yearlong courses —literature, philosophy, and historical and political thought — in which students read the foundational works of the Western tradition.	Perspectives on Science and Engineering is a lecture and discussion course for about 75 selected freshmen who have exceptionally strong backgrounds in science or mathematics. The yearlong course explores a broad range of topics, exposes students to questions at the frontiers of science, and connects the first-year students to York’s Scientific community.
Academic Advising is a collective effort by the residential colleges, academic departments and various offices connected to York University Dean’s office. Students’ primary academic advisors are their residential college deans, to whom they may always turn for academic and personal advice. The deans live in residential colleges and supervise the advising networks in the college. Students also have a freshman advisor who is a York faculty member or administrator affiliated with their advisees’ residential college. Each academic department has a director of undergraduate studies (DUS) who can discuss with students the department’s course offerings and requirements for majors.	Science and Engineering Undergraduate Research York is one of the world’s foremost research universities. Independent engineering research and design projects and scientific research are an essential part of undergraduate science education at York. Science students can begin conducting original research as early as the freshman year. Ninety-five percent of undergraduate science majors engaged in research with faculty mentors.

8 . Many people learn at an early age to associate the color red with danger. So might it make sense to print medication   ________ in red ink? And since the color blue is known to call to mind the freedom of open skies, might it help artists to   ________ in a studio painted in that color? According to new research into how the brain reacts to ________ , the answer to both of these questions is yes. The study revealed that the color red seems to improve a subject’s attention to ________ , while blue appears to stimulate creativity—all without the subject realizing that his or her brain is being influenced.

“People are not ________ this effect at all,” marveled the study’s lead researcher Juliet Zhu, who studies the effects of environmental cues on behavior. To study the brain’s response to specific colors, Zhu’s team administered a series of   ________ tests to college students. For most of the tests, the students were placed in front of a computer screen that was colored either red or blue.

The researchers found that when the screen was red, subjects performed better on detail-oriented tasks. In one test,   ________ , students were asked to memorize a list of words. Zhu found that students who studied the list displayed on a red screen were able to recall more words than students who studied the list on a ________ screen.

In other tests, creative abilities seemed to be ________ by looking at the color blue. For instance, the students were asked to brainstorm potential uses for bricks. Students sitting in front of blue screens tended to come up with ideas that were   ________ , such as “make a paperweight” and “build a pet scratching post.” Students sitting in front of a red screen, on the other hand, were more likely to list ________ uses for bricks, such as “build a house.”

Researchers concluded from the tests that seeing red causes people to take the extra time to think ________ when performing detail-oriented tasks, such as ________ , proofreading— and, of course, reading those all-important warning labels. ________ most people learn early in their development that red signifies potential danger, Zhu said, seeing red perhaps helps people to slow down in order to perform at their best in a potentially risky situation. Seeing blue, on the other hand, produces images of the sky, freedom and peace. Perhaps these images, researchers supposed, ________ feelings. “It’s really this learned association with these colors that drives these different motivations,” Zhu said.
