Two high school students have identified four new planets in distant space about 200-light-years from Earth, making them "the youngest astronomers" to make such a discovery.

Kartik Pingle, 16, and Jasmine Wright, 18, who both attend schools in Massachusetts, participating in the Student Research Mentoring Program (SRMP). Along with the help of Tansu Daylan, an MIT doctor for Astrophysics and Space Research, the students studied and analyzed data from the Transiting Exoplanet Survey Satellite (TESS). Together they focused on Tess Object of Interest (TOI) 1233, a nearby, bright sun-like star and here they found four planets rotating (旋转) around the star. "We were looking to see changes in light over time," Pingle explained. "The idea is that if the planet transits the star, or passes in front of it, it would periodically cover up the star and decrease its brightness. "

While studying 1233, Pinglé and Wright had at least hoped to find one planet, but were overwhelmed with joy when a total of four were spotted. "I was very excited and very shocked. " Wright said. "We knew this was the goal of Daylan's research, but to actually find a multiplanetary system, and be part of the discovering team, was really cool. "

Three of the newly discovered planets are considered as "sub-Neptunes", which are gaseous (气态的), but smaller to the Neptune that lives in our solar system. While observing the planets, the team determined each one completes their orbit around 1233 every six to 19. 5 days. However, the fourth planet is labeled a "super-Earth" for its large size and rockiness-this one orbits around the star in just under four days.

"We have long been studying planets beyond our solar system and with multi-planetary systems, the two young students are kind of hitting the jackpot. They are really blessed." Daylan said. "The planets originated from the same disk of matter around the same star, but they ended up being different planets with different atmospheres and different climates due to their different orbits. So, we would like to understand the fundamental processes of planet formation and evolution using this planetary system. "

Daylan added that it was a "win-win" to work with Pinglé and Wright on the study. "As a researcher, I really enjoy interacting with young brains that are open to experimentation and learning and have minimal bias." he said. "I also think it is very beneficial to high school students, since they get exposure to cutting-edge research and this prepares them quickly for a research career."

(1) How did the two students identify the four planets? A. By interacting with other young brains. B. By helping professor Tansu Daylan with the data. C. By studying Neptune that lives in our solar system. D. By analyzing the change of brightness of star 1233.
(2) What is the main idea of paragraph 4? A. The features of the newly-discovered planets. B. The great efforts made by the two students. C. The comparison between the two star systems. D. The significance of the discovery of the planet.
(3) Which of the following is closest in meaning to hitting the jackpot in paragraph 5? A. Succeeding in something luckily. B. Achieving the goal easily. C. Making a discovery difficultly. D. Performing a task carefully.

    When "Rise of the Planet of the Apes" was first shown to the public last month, a group of excited animal activists gathered on Hollywood Boulevard. But they weren't there to throw red paint on fur-coat-wearing film stars. Instead, one activist, dressed in a full-body monkey suit, had arrived with a sign praising the filmmakers: "Thanks for not using real apes (猿)!"

    The creative team behind "Apes" used motion-capture (动作捕捉) technology to create digitalized animals, spending tens of millions of dollars on technology that I records an actor's performance and later processes it with computer graphics to create a final image (图像). In this case, one of a realistic-looking ape.

    Yet "Apes" is more exception than the rule. In fact, Hollywood has been hot on live animals lately. One nonprofit organization, which monitors the treatment or animals in filmed entertainment, is keeping tabs on more than 2,000 productions this year. Already, a number of films, including "Water for Elephants," "The Hangover Part Ⅱ" and "Zookeeper," have drawn the anger of activists who say the creatures acting in them haven't been treated properly.

    In some cases, it's not so much the treatment of the animals on set in the studio that has activists worried; it's the off-set training and living conditions that are raising concerns. And there are questions about the films made outside the States, which sometimes are not monitored as closely as productions filmed in the Sates.

(1) Why did the animal activists gather on Hollywood Boulevard? A. To see famous film stars. B. To oppose wearing fur coats. C. To raise money for animal protection. D. To express thanks to some filmmakers.
(2) What does paragraph 2 mainly talk about? A. The cost of making "Apes." B. The creation of digitalized apes. C. The publicity about "Apes." D. The performance of real apes.
(3) What does the underlined phrase "keeping tabs on" in paragraph 3 probably mean? A. Listing completely. B. Directing professionally. C. Promoting successfully. D. Watching carefully.
(4) What can we infer from the last paragraph about animal actors? A. They may be badly treated. B. They should take further training. C. They could be traded illegally D. They would lose popularity.
