It weighed about 10,000 tons, entered the atmosphere at a speed of 64,000 km/h and exploded over a city with a blast of 500 kilotons. But on 15 February 2013, we were lucky. The meteorite that showered pieces of rock over Chelyabinsk, Russia, was relatively small, at only about 17 metres wide. Although many people were injured by falling glass, the damage was nothing compared to what had happened in Siberia nearly one hundred years ago. Another relatively small object (approximately 50 metres in diameter) exploded in mid-air over a forest region, flattening about 80 million trees. If it had exploded over a city such as Moscow or London, millions of people would have been killed.
By a strange coincidence, the same day that the meteorite terrified the people of Chelyabinsk, another 50m-wide asteroid passed relatively close to Earth. Scientists were expecting that visit and know that the asteroid will return to fly close by us in 2046, but the Russian meteorite earlier in the day had been too small for anyone to spot.
Most scientists agree that comets and asteroids pose the biggest natural threat to human existence. It was probably a large asteroid or comet colliding with Earth which wiped out the dinosaurs about 65 million years ago. An enormous object, 10 to 16 km in diameter, struck the Yucatan region of Mexico with the force of 100 megatons. That is the equivalent of one Hiroshima bomb for every person alive on Earth today.
Many scientists, including the late Stephen Hawking, say that any comet or asteroid greater than 20 km in diameter that hits Earth will result in the complete destruction of complex life, including all animals and most plants. As we have seen, even a much smaller asteroid can cause great damage.
The Earth has been kept fairly safe for the last 65 million years by good fortune and the massive gravitational field of the planet Jupiter. Our cosmic guardian, with its stable circular orbit far from the sun, sweeps up and scatters away most of the dangerous comets and asteroids which might cross Earth’s orbit. After the Chelyabinsk meteorite, scientists are now monitoring potential hazards even more carefully but, as far as they know, there is no danger in the foreseeable future.

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions from 30 to 34.
Each year, the Academy Awards, better known as the “Oscars”, celebrate the best films and documentaries with categories ranging from acting, directing and screenwriting, to costumes and special effects. This year, 9-year-old Quvenzhané Wallis joins the list of kids who have taken the movie business by storm, as she competes for the best actress award for her role as ‘Hushpuppy’ in the film “Beasts of the Southern Wild”.
The Academy of Motion Picture Arts and Sciences is made up of filmmakers in all fields. The group ranks their favorites in each category. Oftentimes Oscar recognition can take many years, but for some lucky and talented individuals that honor comes early in life.
Newcomer Quvenzhané Wallis (pronounced Kwe-VEN-zhah-nay) portrayed ‘Hushpuppy,’ a young girl fighting to survive in a poor Mississippi Delta community prone to devastating flooding. In the film, Wallis learns to find food in the wilderness, escapes a homeless shelter and deals with the death of her father. She will be the youngest ever nominee in the best actress category at nine years old.
Born in Houma, LA., Quvenzhané was just five years old when she auditioned for Beasts of the Southern Wild. Since auditions for the role of Hushpuppy were only open to 6-9 year olds, Quvenzhané’s mother lied on the initial paperwork to allow her daughter to audition. When director Benh Zeitlin saw her audition however, he immediately recognized her as the best pick for this strong and independent young character.

VII. Read the text and questions below. For each question, circle the letter you choose A, B, C or D.
Even before the turn of the century, movies began to develop in two major directions: the realistic and the formalistic. Realism and formalism are merely general, rather than absolute, terms. When used to suggest a tendency toward either popularity, such labels can be helpful, but in the end they are still just labels. Few films are exclusively formalist in style, and fewer yet are completely realist. There is also an important difference between realism and reality, although this distinction is often forgotten. Realism is a particular style, whereas physical reality is the source of all the raw materials of film, both realistic and formalistic. Virtually all movie directors go to the photographable world of their subject matter, but what they do with this material - how they shape and manipulate it - determines their stylistic emphasis.
Generally speaking, realistic films attempt to reproduce the surface of concrete reality with a minimum of distortion. In photographing objects and events, the filmmaker tries to suggest the copiousness of life itself. Both realist and formalist film directors must select (and hence emphasize).
certain details from the chaotic sprawl of reality. But the element of selectivity in realistic films is less obvious. Realists, in short, try to preserve the illusion that their film world is not manipulated, an objective mirror of the : actual world. Formalists, on the other hand, make no such pretense. They deliberately stylize and distort their raw materials so that only the very naive would mistake a manipulated image of an object or event for the real thing.
We rarely notice the style in a realistic movie; the artist tends to be self-effacing. Some filmmakers are more concerned with what is being shown than how it is manipulated. The camera is used conservatively. It is essentially a recording mechanism that reproduces the surface of tangible objects with as little commentary as possible. A high premium is placed on simplicity, spontaneity, and directness. This is not to suggest that these movies -lack artistry, however, for at its best the realistic cinema specializes in art that conceals art.
What does the passage mainly discuss?




A.Acting styles
B.Film plots
C.Styles of filmmaking
D.Filmmaking 100 years ago
