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.

4 . Directions: Read the following passage. Summarize the main idea and the main point(s) of the passage in no more than 60 words. Use your own words as far as possible.

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.

5 . 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.

6 . 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.

8 . Engaging in Family Meals

Engaging in family meals may be a matter of improving communication and support at home. A new study in the Journal of Nutrition Education and Behavior, published by Elsevier, connects less family discouragement and better family communication with a higher likelihood to eat evening family meals and family breakfasts together, and not in front of a television. The researchers surveyed 259 patients who participated in weight management and weight loss programs at the Ohio State University or Wake Forest University.     1    

“It’s important to note all family members in the home have influence,” lead study author Keeley J. Pratt, PhD, the Ohio State University, Columbus, OH, USA, said of the findings that any family member can influence the adoption and maintenance of healthy patterns and behaviors in the home.     2     The study also found parents who perceived their child to be overweight were more than four times as likely to talk to them about the kid’s weight, also called “weight talk.”

“While open communication with children about health is beneficial, it’s important to ensure communication directly about children’s weight is not harmful in their development of a healthy body image and behaviors. That includes older children and adolescents who are at greater risk of developing eating disorders and disordered eating behaviors,” Professor Pratt said.     3     Families with younger children, regardless of gender, were more likely to eat family dinners and breakfasts together, and parents of older children were more likely to talk about their own weight with the child. As kids grow up, the relationship between kids and their parents becomes better.

    4     “Understanding these associations will provide essential evidence needed to design future family-based interventions for these patients to help in their behavior change and weight loss, prevent the beginning of obesity in children, and enhance positive family meal practices and healthy communication about weight,” Professor Pratt said.

A．The study shows parents of older children were more likely to talk about their own weight with the child.

B．They found parents with better family communication were more likely to participate in family meals.

C．There was no significant difference between male and female children in this study.

D．This was the first study specifically to examine the home eating habits of adult patients.

E．Previous study has shown parental obesity (肥胖) is the strongest risk for children’s obesity.

F．Someone has no power to influence the family, but they are influencing each other.
