COOL INVENTIONS
From school to band Practice, the Venturi Eclectic is an Earth-friendly way to get Where you want to go. This battery-powered, zero-emission (meaning it doesn't pollute the air) vehicle runs mainly on renewable energy. Solar panels on the Eclectic's roof absorb sun rays when you're driving. On windy days, you can connect a machine to the car's roof that collects energy from the wind while you're parked. The Eclectic's top speed is 28 miles an hour; the battery lasts for 31 miles before it needs to be recharged. Zipping (迅速行进) around the neighborhood has never been better.
Here's an eco-friendly way to tell time: Simply fill the Bedol Water-powered Clock's tank (箱) with water, add some lemon juice, and the clock will display the time without the need for environmentally harmful batteries. There are two sets of metal electrodes (电极) inside the water tank. Water contains ions (离子) that carry negative and positive charges. These ions complete a charge between the electrodes, creating enough energy to power the clock. Just refill the tank every few weeks, and this clock will keep on ticking.
Bloodhound SuperSonic Car (SSC) will be the first car to attempt to break the l,000-mile-an-hour barrier. (The current record is 763 miles an hour.) A concept for now, the rocket-shaped car gets its initial push to 350 miles an hour from a jet engine. Then a rocket fires up, pushing the SSC past 1,000 miles an hour. In order to keep the car streamlined (流线型的), the driver lies back at a 45-degree angle.
You're having a blast at your friend's birthday party. But when it's time to bring out the cake, everyone crowds around, blocking your view. No worries. Throw the Triops into the air, and this clever camera captures the view from above. The Triops can take three pictures at once, each from different angles. You can also record sounds and command the Triops to start shooting whenever it hears that noise. That's one smart camera.According to the passage, the Venturi Eclectic .

People like different kinds of vacations. Some go camping. They swim, fish, cook over a fire and sleep outside. Others like to stay at a hotel in an exciting city. They go shopping all day and go dancing all night. Or maybe they go sightseeing to places such as Disneyland, the Tai Mahan or the Louver.
Some people are bored with sightseeing trips. They don’t want to be “tourists”. They want to have an adventure--a surprising and exciting trip. They want to learn something and maybe help people too. How can they do this? Some travel companies and environmental groups are planning special adventures. Sometimes these trips are difficult and full of hardships, but they’re a lot of fun. One organization, Earth watch, sends small groups of volunteers to different parts of the world. Some volunteers spend two weeks and study the environment. Others work with animals. Others learn about people of the past.
Would you like an adventure in the Far North? A team of volunteers is leaving from Mormons, Russia. The leader of this trip is a professor from Alaska. He’s worried about chemicals from factories. He and the volunteers will study this pollution in the environment. If you like exercise and cold weather, this is a good trip for you. Volunteers need ski sixteen kilometers every day.
Do you enjoy ocean animals? You can spend two to four weeks in Hawaii. There, you can teach language to dolphins. Dolphins can follow orders such as “Bring me the large ball.” They also understand opposites. How much more can they understand? It will be exciting to learn about these intelligent animals. Another study trip goes to Washington State and follows orcas. We call orcas “killer Whale”, but they’re really dolphins—the largest kind of dolphin. This beautiful animal travels together in family groups. They move through the ocean with their mothers, grandmothers and great-grandmothers. Ocean pollution is chasing their lives. Earth watch is studying how this happens.
Are you interested in history? Then Greece is the place for your adventure. Thirty-five hundred years ago a volcano exploded there, on Santorum. This explosion was more terrible than Karate or Mount Saint Helens. But today we know a lot about the way of life of the people from that time. There are houses, kitchens, and paintings as interesting as those in Pompeii. Today teams of volunteers are learning more about people from the past.
Do you want a very different vacation? Do you want to travel far, work hard and learn a lot? Then an Earth watch vacation is for you.The Tai Mahan may be _______.

When in 1789, George Washington became the first president of the United States, there was no permanent capital in which to house the government.

A desert is a beautiful land of silence and space. The sun shines, the wind blows, and time and space seem endless. Nothing is soft. The sand and rocks are hard, and many of the plants even have hard needles instead of leaves.
The size and location(分布) of the world’s deserts are always changing. Over millions of years, as climates change and mountains rise, new dry and wet areas develop. But within the last 100 yeas, deserts have been growing at a frightening speed. This is partly because of natural changes, but the greatest makers are humans.
Humans can make deserts, but humans can also prevent their growth. Algeria Mauritania is planting a similar wall around Nouakchott, the capital. Iran puts a thin covering of petroleum(石油) on sandy areas and plants trees. The oil keeps the water and small trees in the land, and men on motorcycles(摩托车) keep the sheep and goats away. The USSR and India are building long canals to bring water to desert areas. In this passage, “needles” refers to _______.
| A．small, thin pieces of steel. |
| B．long, thin pieces of branches. |
| C．small pointed growth on the stem(茎) of a plant. |
| D．small, thin pieces of sticks. |
Which of the following is NOT true?
| A．The greatest desert makers are humans. |
| B．There aren’t any living things in the deserts. |
| C．Deserts have been growing quickly. |
| D．The size of the deserts is always changing. |

| C．Deserts are lands of silence and space. |

The deserts of the world are not all covered with sand. Many of them have surfaces of rock or clay or small stones. They are not flat, either. They often have high hills and deep valleys. There is some plants’ life in many parts of the desert. There is little rain in the desert, but it does fall often enough for most plants.
The deserts of the world are not uninhabited(not lived by people). People also live outside oases(绿洲), but these people are not farmers. They have camels, goats, donkeys, sheep, etc. These animals can live on the desert plants and do not need much water.
The people of the desert have to move constantly from place to place, they must always look for grass or desert plants for their animals. They usually live in tents. When there is no more food for their animals, they fold up their tents, pat them on their camels and donkeys, and move to another place. In good years, when there is enough food for their animals, they trade their skins and their goats and camel hairs with the people of oases for wheat and fruit. But in bad years, when there is not enough food for their animals, the people of the desert would attack the oases people. But they are also hospitable, no man in the desert would ever refuse to give a stranger food and water.according to the passage, deserts are mostly made up of _______.

“If it rings one more time, I’ll hang up,” Amy thought hopefully, as she waited for someone to answer. Apologizing wasn’t an easy thing to do.
