Suddenly, a sharp cry of Barney came into the mother's ears, and Lisa rushed into the backyard in a hurry and found a big snake entwining the little child with its terrible body and trying to eat the boy as its delicious dish! It was a boa ! Lisa was terrified and quite angry. She made up her mind to save her son from the snake's mouth. It was fearless mother love that made Lisa forget what she faced. She took up an old hoe from the ground and beat the boa with all her might. One...two... With the hoe, Lisa beat the snake repeatedly, but useless. The little boy's voice and breath were getting weaker and weaker. Lisa's heart was broken and she got nearly mad. Suddenly Lisa put away the hoe and threw herself to the boa, opening her mouth and bit into the boa's back as if trying to eat a rare steak . Lisa was really mad! Blood was spurting out of the boa's body and covered most of Lisa's body. The boa was so badly wounded that it let go of Barney and moved back into the forest hurriedly. It had never known how a man had such terrible sharp teeth! On halfway home, the boa died. It was fearless mother love that saved the little boy. Question: Lisa failed in fighting against the boa at first just because _ .

A stunt person is a man or woman who does all the dangerous bits of acting work in films or on TV. This can be anything from a simple fall into a swimming pool, or walking off the top of a tall building. It sounds like a job that you would have to be made to try, but there are actually lots of people who want to do it. Sarah France, twenty-four, is one of Britain's sixteen professional stunt women ---there are one hundred and sixty stunt men in the country. We asked Sarah how she came to be a stunt woman. "When I was young I was trained to be a dancer, and for seven years after school I was hardly out of work. A dancer's life is pretty short, though, and my father suggested I should think about doing stunt work after I'd given up dancing. I thought about it for the next two years and decided to have a go. For six months, I worked really hard every day. I had to learn different skills---swimming, jumping, horse -riding, etc." Sarah finished the course in just five months and applied to the office which decides whether you're accepted as a professional stunt person or not. Two weeks after she was accepted, Sarah was throwing off the Great Wall of China in Superman IV. "I was very lucky to get work so quickly. I had a small part, playing a traveler who fell off the Wall after an earthquake. The traveler's life was saved by Superman, of course! Actually, I fell forty-five feet into a pile of cardboard boxes! You can't use anything softer than that or you will be brought back into view of the cinema. Instead you just have to learn to fall properly. It's quite dangerous but I enjoy it." Question: Soon after Sarah got her new job as a stunt person, _ . Options: A: an earthquake took place near the Great Wall B: she fell off the Great Wall and hurt herself C: she was asked to act in Superman IV D: she learned how to fall properly

Read the article and select the best answer. Article: Death Valley is the lowest, hottest, driest area in North America. This California National Park has less than 5 cm of rainfall a year and temperature up to 53degC in summer. That's enough to keep Americans away during the hottest months from June to August. But it is the high temperature and terrible heat that draw their most crazy fans, the foreign tourists. From all over the world, they come to the valley floor in cars, carrying maps and water bottles, and fanning themselves with newspapers to keep cool. About 1.3 million visitors enter the park each year, from June through August. 90% of them are foreigners. They go there to experience the summer heat that gives Death Valley its name. The average high in July is 53.2 degC and the low 30 degC. For August, the average high is 52.2 degC and the low 29.4 degC. So what do Americans think of the foreign visitors who arrive for the heat, just when locals from the United States try to avoid it? Park manager Brenda Henson says, " The foreigners want to experience the heat in Death Valley. We think it's crazy." In fact, Death Valley is a series of salt flats 225 km long and 6 km to 26 km wide. Birds and animals are largely absent, and only the plants have some chance of existence in this extreme place. One tourist from Paris concluded, " We come to it because we can tell all our friends and family that we've been to the hottest place in the world." Question: What would be the best title for the passage? Options: A: Crazy Fans of Death Valley. B: Importance of Death Valley. C: Beauty of California National Park. D: The Best Tourist Attraction in North America.

Read the article and select the best answer. Article: For the first time, scientists have found a planet beyond the solar system that not only is the same size as Earth, but has the same proportions of iron and rock, a key step in an ongoing quest to find potentially habitable sister worlds. The planet, known as Kepler-78b, circles a star that is slightly smaller than the sun located in the constellation Cygnus , about 400 light years away. Kepler-78b was discovered last year with NASA's now-idled Kepler space telescope, which detected potential planets as they circled in front of their parent stars, blocking a bit of light. That measurement not only revealed that Kepler-78b was ly small, with a diameter just 20 percent larger than Earth's, but that it was practically orbiting on the surface of its host star. Scientists do not know how the planets ended up so close to their host stars. While the planet's presumably molten surface and hot temperatures make it ill-suited for life, two independent teams of astronomers jumped at the opportunity to follow up the discovery with ground-based measurements to try to determine the density of Kepler-78b. In two papers in this week's journal Nature, the teams report that not only were they successful, but that they came to the same conclusion: Kepler-78b has roughly the same density as Earth, suggesting that it also is made primarily of rock and iron. Kepler-78b is among a dozen or so recently discovered small planets that orbit very close to their parent stars. Kepler-78b, for example, completes an orbit in just 8.5 hours. Question: The word " density" in the text suggests a measurement of the planet's _ . Options: A: volume B: size C: weight D: thickness
