There's only one place, and that's Hollywood, in California. The scenes you see from the tourist train are film sets in the Universal Studios, one of the 32 and largest movie companies in the USA.A visit to the Universal Studios brings 33 memories of great days of Hollywood, the films and the stars. But they are only memories. Hollywood isn't quite the same as it used to be. Costs have 34 and confidence has gone down. Movie-makers are afraid to spend their money 35 expensive new ideas. Instead, they repeat old ones.The film industry is changing fast. Teenagers still go out to the movies. The theatre is a good place to meet friends away from home. But older people 36 stay at home to watch series, like Dynasty. These soap operas(肥皂剧)show 37 , powerful families living in beautiful homes and wearing beautiful clothes. But the actors and actress are nearly all middle-aged, like many of the people who watch them.38 soap operas are keeping the film-makers of Hollywood in business, big films are still being made in America. But more and more of them are made outside Hollywood. New York is the most important new center, but there are many others as well.

Friction happens when two things that aren’t very smooth rub together to make heat energy. The faster you rub two things together, the more friction (and heat) you can make. Let’s discover friction!*WHAT YOU’LL NEED:Soap, Water, Your hands*WHAT TO DO:1. Make sure your hands are dry.2. Rub your hands together until you feel the heat of your hands.3. Now, use soap and water to get your hands very slippery (滑的).4. Try to make friction happen while your hands are slippery.5. Please write down what has happened.*LET’S TALK!Friction is an energy that happens when two things rub together. When friction happens, it makes heat! When your hands are sli ppery, they won’t make very much friction and your hands won’t get so hot.*DID YOU KNOW?1. Friction happens when you stop your fast running bike.2. Ancient people made fire by rubbing two pieces of wood together. Friction happened though they didn’t kno w it.* WORK WITH PARENTSFriction is everywhere. Have you ever noticed situations where friction is happening? If not, ask your parents to take you out in a car. If it is not too hot, touch the tires (轮胎) of the car before and after a short drive to see how much warmer they get from friction.41. This text is most probably _____.A. a science reportB. a car advertisementC. a script for a filmD. a maths problem42. You’d better make your hands _____ to get heat when you rub them.A. slipperyB. dryC. wetD. smooth43. What does the word “friction” in this text mean in Chinese?A. 摩擦B. 冷却C. 膨胀D. 震动44. Which of the following is NOT an example of friction?A. Stopping a fast running bike.B. Making fire by rubbing two pieces of wood together.C. Hands rubbing.D. Seeing the tires of a car.BRecently, American scientists named ten super animals, which are called "super" because these animals have powers that even human beings don't have. Here shows you some of their magic and secrets.MiceSuper power: Mice can't see well, but their whiskers(胡须)in front of their mouths help them to "see". When a mouse's whiskers touch something, the mouse gets an idea of what's around it.Mice are good jumpers, climbers and swimmers. They usually walk, run or stand on all four legs. But when they eat, fight or look for directions, they stand on their back legs. When they run, mice use their tails for balance. When a mouse is frightened, the end of its tail stands up.SharksSuper power: Sharks are the best animal hunters. Their brains can sense other animals' electric fields. Sharks can find other animals even if they hide in sand or mud.Sharks look huge and dangerous but out of more than 360 kinds, only a few have attacked people without being troubled. Not all sharks are huge. Some that live in deep water are only 22 centimeters long. The biggest kind can grow to 12 meters long.Hummingbirds(蜂鸟)Super power: Hummingbirds can see what we can't see! Light is made up of waves. We can only see light waves that are about 380 to 780 nanometers(纳米)long. But hummingbirds can see some light waves that we can't see! Some things look colorless to humans but are very colorful for hummingbirds.Hummingbirds are very small birds that live mostly in North and South America. The smallest kind weighs l.8 grams. Even the largest weighs only 24 grams. Hummingbirds can beat their wings very quickly —15 to 80 times per second. A hummingbird eats more than his own weight in nectar(花蜜) each day. So they have to visit hundreds of flowers every day.45. The best title for the passage may probably be _______.A. Mice, Sharks and HummingbirdsB. Amazing Animals with Super PowersC.
