3 . Mandara seemed to know something big was about to happen. So she let out a yell, caught hold of her 2-year-old daughter Kibibi and climbed up into a tree. She lives at the National Zoo in Washington, D.C.

And on Tuesday, August 23rd, witnesses say, she seemed to sense the big earthquake that shook much of the East Coast before any humans knew what was going on. And she’s not the only one. In the moments before the quake, an orangutan (猩猩) let out a loud call and then climbed to the top of her shelter.

“It’s very different from their normal call,” said Brandie Smith, the zookeeper. “The lemurs (monkey-like animals of Madagascar) will sound an alarm call if they see or hear something highly unusual.”

But you can’t see or hear an earthquake 15 minutes before it happens, can you? Maybe you can — if you’re an animal. “Animals can hear above and below our range of hearing,” said Brandie Smith. “That’s part of their special abilities. They’re more sensitive to the environment, which is how they survive.”

Primates(灵长类）weren’t the only animals that seemed to sense the quake before it happened. One of the elephants made a warning sound. And a huge lizard (蜥蜴) ran quickly for cover. The flamingoes (a kind of bird) gathered before the quake and stayed together until the shaking stopped.

So what kind of vibrations（震动）were the animals picking up in the moments before the quake? Scientist Susan Hough says earthquakes produce two types of waves — a weak “P” wave and then a much stronger “S” wave. The “P” stands for “primary”. And the “S” stands for “secondary”. She thinks the “P” wave might be what set the animals off.

Not all the animals behaved unusually before the quake. For example, Smith says the zoo’s giant pandas didn’t jump up until the shaking actually began. But many of the other animals seemed to know something was coming before it happened. “I’m not surprised at all,” Smith said.

The honors program is for students who have enjoyed their experience in research with a guide teacher and are looking for a highlight experience during their final year. The program has specific requirements for our majors described below.

Students participate in the honors program during their final year. Students who expect to have a 3.5 accumulative GPA by the fall of senior year should have identified a guide teacher and applied for NBB honors by May 1st of their third year. Applications are brief and include basic information such as guide teacher name, project title, and current GPA.

During senior year, honors students take two research-experience courses. Participation in these courses includes at least 12 hours of work on the research project each week as well as weekly meetings with other researchers to develop professional skills.

The majority of our major work with guide teachers in research experiences, and many students co-author manuscripts(手稿) published in leading journals. However, only honors students are guided and helped through the process of writing an essay. All students’ essays are published online through the university library and, after the data being forbidden to be included in other articles, the essays are available to search.

5 . A fresh and gentle wind on your face, soft sand under your feet and blue waters as far as the eye can see. Is there any other Olympic sport that is played in such pleasant conditions as beach volleyball？

“I’ve gone to a lot of beautiful places, and met a lot of beautiful people. That wouldn’t have happened if I had been playing another sport.” said Randy Stoklos, America’s most famous beach volleyball player.

The sport began as a four-a-side game on beaches in Southern California in the 1920s. The first recorded two-man game took place there in 1930, and the first tournament (锦标赛) was held in Los Angeles 18 years later. The winners were awarded a case of Pepsi. In the 1950s, women started playing and the sport soon spread to Europe and South America. Yet at that time, beach volleyball was more an entertainment show than a sport, with beauty contests included. The Association of Volleyball Professionals was founded in 1983 and beach volleyball developed into a fast, athletic sport. Its world-wide popularity won beach volleyball a place at the 1996 Olympics in Atalanta, where 24 male teams and 16 female teams took part. At present, the US and Brazil are the best in the world at beach volleyball.

The game came to China in the early 1990s and there have been national tournaments since 1994. It became an official event at the Eighth National Games in 1997. China’s You Wenhui and Wang Lu finished ninth in the women’s beach volleyball world championships in Brazil.
