TV Shows and Long Bus Trips Long bus rides are like television shows. They have a beginning, a middle, and an end-- with ads thrown in every three or four minutes. The ads are unavoidable. They happen whether you want them or not. Every couple of minutes a billboard appears outside the bus window."Buy Super Clean Toothpaste.""Drink Good'n Wet Root Beer.""Fill up with Pacific Gas." Only if you sleep, which is equal to turning the television set off, are you spared the unending cry of "You Need It! Buy It Now!" The beginning of the ride is comfortable and somewhat exciting, even if you've traveled that way before. Usually some things have changed--new houses, new buildings, sometimes even a new road. The bus driver has a style of driving and it's fun to try to figure it out the first hour or so. If the driver is particularly daring, the ride can be as exciting as a suspense story. Will the driver pass the truck in time? Will the driver move into the right or the left-hand lane?After a while, of course, the excitement dies down. Sleeping for a while helps pass the middle hours of the ride. Food always makes bus rides more interesting. But you've got to be careful of what kind of food you eat. Too much salty food can make you very thirsty between stops. The end of the ride is somewhat like the beginning. You know it will soon be over and there's a kind of expectation and excitement in that. The seat, of course, has become harder as the hours have passed. By now you've sat with your legs crossed, with your hands in your lap, with your hands on the arm rests--even with your hands crossed behind your head. The end comes just at the right time. There are just no more ways to sit. According to the passage, what do the passengers usually see when they are on a long bus trip? A) Buses on the road. B) Films on television. C) Advertisements on billboards. D) Gas stations.

We bet that on cold wintry days, many of you love to stay in your warm home and, every now and then, come out into the kitchen for a snack. Unfortunately, plenty of creepy-crawly critters like to do the same thing! Winter is the time when bugs invade your house without an invitation. The season can be tough for such creatures. In winter the air is cold, the ground is hard and many trees have no leaves. So bugs do what they have to do to survive. Monarch butterflies head south to warmer climates. Ants crowd in deep underground colonies and eat food they have been storing all year. Many insects go into a deep sleep called diapause. There're different kinds of diapause, but all are similar to hibernation, a time when bigger animals become inactive in the cold. Insects go into an inactive period, too, but it often isn't when the temperature drops. They rely on more dependable signals in the environment. For example, many insects can tell how much sunlight there's each day. They use that to tell themselves when to shut down. Bugs are cold-blood-ed, meaning that their inside temperature is the same as the outside. They can't move much when it gets below 40 degrees Fahrenheit. So they search for any warm place. They're looking for protection. These guys have been doing this for 300 million years, so they don't really know they're coming into your house. The home is a recent event in terms of their evolutionary behav-ior. They enter through tiny cracks or come in unnoticed on your clothes or shoes. Remember that they may be invading your homes for warmth and food, but they don't care about humans. According to the text, what is diapause? A) It is the same as the animals' hibernation B) It often appears in warm areas all the year. C) It is done to keep bugs active in winter. D) It is a deep sleep similar to hibernation.
