阅读下列短文,从每题所给的四个选项 (A 、B 、C  和 D )中,选出最佳选项。

    Christmastime in the city brings forests of trees already cut and waiting to be sold. But some people like to drive to tree farms. Others wait for their trees to come to them. They order one from the pages of a catalog or on the Internet. Some say the easiest thing of all is to buy a man­made tree with Christmas lights already on it. No falling needles to have to clean up.

    The National Christmas Tree Association says 33,000,000 real trees were sold last year, compared to 9,000,000 man­made ones. Man­made trees generally cost more, but they can be reused. Most natural trees are cut up and recycled, but some people buy trees that can be planted.

    Most Christmas trees are now grown on farms instead of in forests. Twenty-one thousand tree farmers in the United States grow Christmas trees on more than 180,000 hectares. Oregon was the leading producer last year.

    Twenty-two percent of people who bought real trees last year chose them at a farm. Two percent of those people cut the trees themselves. The next most popular places were big stores like Walmart and Home Depot. Groups like the Boy Scouts also sell Christmas trees. But some people pay nothing for theirs. They steal it.

    Cornell University in Ithaca, New York, has many pretty evergreens. Some years ago, a university worker found a way to keep them there. A month before Christmas, workers treated them with “pink ugly mix”. It contains water and red food colour. The bright colour starts to disappear after about a month. It can take longer, however. Cornell decided not to use the mix this year, but the idea has spread.

(1)、Man­made trees are chosen for Christmas partly because________.
A、they cost less than real ones B、they are usually sold with gifts C、they look prettier than real ones D、they can be used for more than once
(2)、What can we learn from the passage?
A、Oregon produced the most Christmas trees last year. B、Most Christmas trees come directly from the forests. C、All real trees for Christmas are recycled by Americans. D、Man­made Christmas trees are more popular with Americans.
(3)、People can get their Christmas trees from the following places EXCEPT ________.
A、Oregon B、Home Depot C、Boy Scouts D、Cornell University
(4)、The passage is mainly about________.
A、the important festivals in America B、the origin of Christmas as a holiday C、the way Americans celebrate Christmas D、the popularity of Christmas trees in America

    LEADING INTERNATIONAL SCHOOLS 2019

    Jerudong International School(JIS) , Brunei

    “Achieving Excellence” is the motto of JIS, Brunei. A developing boarding school of 1,700 students, 40% Bruneian, JIS has made itself a leading school in Asia. With almost 200 highly qualified teachers primarily from the UK, the 120-acre single campus (校园) close to both coast and rainforest offers a unique educational environment. There is a Performing Arts Centre, 27 science laboratories, libraries and classrooms.

    The American International School (AIS), Austria

Founded in 1959, AIS is the oldest English-language school in Austria. School programs focus on academics, but also on the development of students' creative and leadership abilities and emotional intelligence. The school recognizes students' special learning styles, trying to make instruction different and allowing students to reach their full potential in different areas.

    Singapore American School (SAS), Singapore

    Founded in 1956, it is one of only a few good non-profit schools in Singapore. For over six decades, SAS has provided students from preschool to Grade 12 a good American education with an international view. The school supports professional development financially and continually sends teachers across the globe to discover new ideas and best practices from influential educational institutions.

    Santa Clara International School (SCIS), Spain

    In the school, when you walk into a classroom, you'll see hands raised, small groups assembled (集合), and presentations underway. You'll find teachers creating cooperative partnerships with students, encouraging them to discover and connect. You'll observe children working on meaningful hands-on projects that build skills and excite creativity. The teaching philosophy is that learning happens everywhere: in the classrooms, in the city, in a museum, on a farm, or just a walk around the neighborhood.

    Can I talk about salary at work? In a word: yes. As HR company Insperity put it in a recent blog post: Can your employees discuss their salaries or wages with their co-workers? Yes. Even if you have a company policy against it? Yes.

    The freedom to discuss your salary at work is a protected right under federal labor law. The National Labor Relations Act of 1935 protects your right to discuss the conditions of your employment, including issues related to safety and pay, even when you're not protected by a union.

    Talking about salary with colleagues can be uncomfortable, since there's such a taboo about discussing money matters, but it's an important step towards achieving equal pay for equal work. One barrier, however, stems from how we think of our own financial worth. Too many people I talk to wrongly consider their salary a reflection of their worthiness, a statement about their skills, experience, or value. At the end of the day, if we can all separate our self-worth from our salaries a bit more, it'll become easier to talk frankly with our colleagues.

    Asking about money outright can be tough, so one trick I've picked up along the way is to ask for your colleagues to confirm or deny. For instance, you might volunteer your salary first and ask "Does that sound about right to you?" by way of comparison. Or, let's say you're interviewing for a promotion to become a manager. You might ask a fellow manager about the kind of salary you should expect by saying, “I'm seeing salaries for this kind of position ranging from $65, 000 to$70, 000—does that seem accurate to you?" This way, even if your colleague isn't comfortable sharing their salary outright, they can help you identify if your expectations are on point or way off.

    It is a question people have been asking for ages—is there a way to turn back the aging process?

    For centuries, people have been looking for a "fountain of youth." The idea is that if you find a magical fountain, and drink from its waters, you will not become old. Spanish explorer Juan Ponce de León searched for waters with magical powers in the early 1500s. But what he found instead is the American State of Florida.

    Researchers in New York did not find a fountain of youth in fact, but they may have found a way to turn back the aging process. It appears the answer may be hidden right between your eyes, in an area called the hypothalamus (丘脑下部).The hypothalamus is part of your brain. It controls important activities within the body, including growth, reproduction and the way we process food.

    Researchers at New York's Albert Einstein College of Medicine found that hypothalamus stem cells also influence how fast aging takes place in the body. What are stem cells? They are simple cells that can develop into specialized cells, like blood or skin cells. Stem cells can also repair damaged parts in the body.

    Professor Dongsheng Cai was the lead researcher in a study on aging in mice. Cai explains in the Journal Nature what they found. "Aging speed can be controlled by a particular place in the body, which is the hypothalamus. And it can be controlled by a particular type of cells, which are hypothalamus stem cells. I think these findings are quite interesting."

    He adds that when the hypothalamus starts aging, so does the body. "So when hypothalamus function is decreasing, particularly the loss of hypothalamus stem cells, this protection against the aging development is lost. It finally leads to aging."

    Using this information, the researchers began trying to activate (激活) the hypothalamus in mice. They did this by putting stem cells from younger mice into middle-aged animals. Later, the researchers examined mice and tested for changes in behavior. They also looked for changes in the strength of the animals' muscles and the way they worked. The researchers say the results show that the treatment slowed aging in the animals.

    Cai says when hypothalamus stem cells, which were derived from young mice was put into middle-aged mice, the mice aged slowly and they also have increased the length of their lives.

    But these results were just from studying mice in a lab. If the mice can live longer, does that mean people could have longer lives? The next step is to see if the anti-aging effects also work in human beings.

    Teenagers who talk on the phone a lot and hold their cell phones up to their right ears score worse on one type of memory test. That's the finding of a new study. That memory damage might be one side-effect of the radiation that phones use to keep us connected while we're on the go.

    Nearly 700 Swiss teens took part in a test of figural memory. This type helps us recall abstract symbols and shapes, explains Milena Foerster. She's an epidemiologist(流行病学家). She worked on the study as part of a team while Foerster was at the Swiss Tropical and Public Health Institute in Basel, Switzerland. Teens participated memory tests twjce, one year apart. Each time, they had one minute to memorize 13 pairs of abstract shapes. Then they were shown one item from each pair and asked to match it with one of five choices.

    The study volunteers also took a test of verbal memory. That's the ability to remember words. The two memory tests are parts of an intelligence test.

    The researchers also surveyed the teens on how they use mobile phones. And they got call records from phone companies. The researchers used those records to estimate how long the teens were using their phones. This allowed the researchers to calculate how big a radiation exposure each person could have gotten while talking.

    All cell phones give off energy in the form of radio frequency electromagnetic fields, or RF-EMFs. Radio and TV broadcasts also use this type of energy. So do microwave ovens and some other gadgets(配件).

    "For a phone, that energy carries information, in the form of calls or texts between phones and cell phone towers. That radiation also can travel into people's bodies as they use their phones. And some of its energy can be absorbed by the body. So far, scientists have not shown that radiation from phones causes harm," says the Federal

    Communications Commission. Research is ongoing, this agency notes.
