Unless we spend money to spot(,) and prevent asteroids now, one might crash into Earth and destroy life as we know it, say some scientists. Asteroids are bigger versions of the meteoroids that race across the night sky. Most orbit the sun far from Earth and don't threaten us. But there are also thousands of asteroids whose orbits put them on a collision course with Earth. But $500 million worth of new telescopes right now, then spend $10 million a year for the next 25 years to locate most of the space rocks. By the time we spot a fatal one, the scientists say, we'll have a way to change its course. Is it worth it? Two things experts consider when judging any risk are (i) How likely the event is; (2) How bad the consequences if the event occurs. Experts think an asteroid big enough to destroy lots of life might strike Earth once every 500,000 years. Sounds pretty rare but if one did fall. It would be the end of the world. "If we don't take care of these bid asteroids, they'll take care of us," says one scientist. "it's that simple." The cure, though, might be worse than the disease. Do we really want fleets(,) of nuclear weapons sitting around on Earth? "the world has less fear from doomsday rocks than from a great nuclear fleet set against them." Said a New York Times article. What do scientists say about the collision of an asteroid with Earth? A) It is very unlikely but the danger exists. B) Such a collision might occur once every 25 years. C) Collisions of smaller asteroids with Earth occur more often than expected. D) It's still too early to say whether such a collision might occur.

Many people are so busy these days that they have no time to cook at home. This becomes a problem because most families love home cooking! The food tastes good and a family meal can bring everyone together. In some families, meals are often the only chance everyone gets to see each other at the same time during the day. Another reason people enjoy home cooking is that it is a way of showing love. A parent who makes some cookies is not just satisfying a child's sweet tooth. He or she is sending a message . The message says, "I care about you enough to spend an hour making cookies that you will eat up in 15 minutes if I let you." There is also something about the smell of home cooking. The smell of cooking makes people happy. It makes most of us feel good and loved--even if we're the ones doing the cooking! Next time you smell a cake making, stop for a moment and pay attention to your mood (,). What's the main idea of the passage? A) Home cooking is important. B) Home cooking feels good and loved. C) People are too busy to cook. D) Home cooking cookies taste better.
