Think about the longest elevator ride that you’ve ever taken. Whether you rose five or 100 floors, it probably took less than a few minutes. Now imagine riding in an elevator higher and higher as it climbs for nearly a day. When you reach the top floor, prepare for views that are really out of this world. You’ll be in space!
Space elevators might sound like a crazy idea, but they’re something scientists have been working on for decades.
At the moment, riding in a capsule is the only way ordinary people can get to and from space. But those rides are very expensive---about $ 25 million per person per flight. Now scientists are making efforts to reduce the expense of those rides.
Researchers are still figuring out the details about how a space elevator might work. One idea is stretching a very long cable — more than 37,000 kilometers — up to space from the earth’s equator (赤道). Objects in space above the equator orbit (绕……的轨道飞行) the earth at the same speed that our planet turns. A weight on the end of the cable would stretch it tight. An elevator tied to the cable could use it to climb up and down.
The only problem is that besides being long, this cable must also be very strong. Storms, including hurricanes might break it. One way to solve this problem is to stretch the cable from the moon instead of from the earth. Airplanes designed to climb higher than a typical jet might take off from the earth and link up with the cable, which would be held in place by the pull of gravity from the earth. An elevator car waiting there would then take riders the rest of the way to the moon. Fueled by solar power, the elevator could transport people and materials without much expense or effort per ride.
1.The first paragraph is presented by _____.
A. asking questions
B. analyzing causes
C. giving an example
D. making a comparison
2.Why have scientists been working on space elevators?
A. To make trips to space cheaper.
B. To help astronauts do research in space.
C. To find a more convenient way to the moon.
D. To prove an assumption which seems crazy.
3. The underlined word “it” in Paragraph 3 refers to _____.
A. the weight
B. the cable
C. an object in space
D. the equator
4. What may make the cable stay in place on the moon?
A. The elevator car on the moon.
B. The elevator fastened to the cable.
C. The pull of gravity from the earth.
D. The speed of the moon orbiting the earth.

Most drinks stating that they are fruit-flavored (水果味道的) contain no fruit at all, while most of the rest contain only a small quantity of fruit, according to a study carried by the British Food Commission.
“Shoppers need to check the labels (标签) before buying drinks, though sometimes the actual content can be non-existent,” said Food Commission spokesperson Ian Tokelove. “Food production is highly competitive. 1. It will increase profits, and consumers won’t always realize they are being tricked.”
Flavorings are focused on the flavors of natural food products such as fruits, meats and vegetables, or creating flavor for food products that do not have the desired flavors. Researchers analyzed the contents of 28 strawberry-flavored products sold in stores. 2. Of the 11 products that did contain strawberries, five of them contained less than one percent real fruit. In addition, each juice box contained nearly eight teaspoons of sugar.
3. Let’s take jam as an example. Some strawberry-flavored jam was labeled as containing no artificial colors, flavors, or sweeteners, but it contained absolutely no strawberries at all.
4. Consumers have the rights to know clearly about what they have bought. Under current UK law, food packages do not have to distinguish between natural and artificial flavoring. “Describing a product as strawberry flavor and covering the surface of the packet with pictures of strawberries is misleading. 5. Unfortunately, it is also legal and widespread,” Tokelove said. “It’s time to take measures to protect the consumers’ rights.”
A. The products which contain real fruit are popular with people.
B. Even products advertised as more natural often contained no fruit.
C. They found that about 60 percent of them didn’t contain any fruit at all.
D. If companies can cut their costs by using flavoring, they are likely to do so.
E. It is important and necessary to demand a small amount of flavoring in the products.
F. Actually the product contains just a tiny percentage of strawberry or even no fruit at all.
G. The Food Commission suggested all flavors used in a product should be listed on the packaging.

Plenty of people dream of traveling to other planets. But “Star Wars” fans can actually visit locations where many of the films’ most famous scenes were shot. Here are some of the places where “Star Wars” comes to life.
Hotel Sidi Driss, Matmata, Tunisia
Perhaps the most famous "Star Wars" landmark in the world, this is where the interiors of Luke Skywalker's childhood home on planet Tatooine were filmed. Centuries ago, Berbers built the underground structure as a real home. Eventually it became a hotel, which George Lucas used to film the first "Star Wars" film. The set decorations came down when the crew left, but were rebuilt in 2000 for "Attack of the Clones." Since then, they've remained, so guests can eat at the table where young master Luke did.
La Grande Dune, outside Nefta, Tunisia
The igloo(冰屋) outside of Luke's house was filmed about 300 kilometers away on the dried-up salt lake of Chott El Jerid. The igloo is still there, reachable with a decent car at the GPS coordinates 33"50'34. 42"N, 7"46'44.48"E.
The surrounding hotels are man-made, to create the illusion (幻觉)that the underground house is next to it. The igloo from the 1977 movie was taken apart, but again rebuilt for "Attack of the Clones," and later restored by a fan. Nearby is La Grande Dune, site of the Dune Sea. About 30 minutes from the igloo is the set of Mos Espa, the spaceport town where Anakin was discovered as a young slave.
Redwood National and State parks, California
Endor, the forest moon home of the furry Ewoks, was filmed among California's giant redwoods. Most of the well-known scenes were shot on private land owned by a lumber company. Since the cast and crew worked on "Return of the Jedi" in 1982, heavy logging has left most of the landscape unrecognizable. But driving through the parks still gives a feel for the set, especially along the Avenue of the Giants highway.
In Grizzly Creek Redwoods State Park and the Humboldt Redwoods State Park, plates were filmed for some chase scenes.
1.Hotel Sidi Driss was originally ________ centuries ago.
A. a hotel
B. Berbers’ real home
C. Luke Skywalker’s childhood home
D. the shooting location of “Attack of the Clones”
2.Which of the following is NOT CORRECT about the igloo in the third paragraph?
A. We can still reach the igloo.
B. The igloo was restored by a fan
C. The igloo was taken apart for “Attack of the Clones”
D. The igloo’s location is at the GPS coordinates 33"50'34. 42"N, 7"46'44.48"E
3. The underlined word “Endor” refers to ____________ in “Star Wars”.
A. an animal B. a person
C. a place D. a company

How to Help a Teenager Make Good Decisions
Habitually poor decision making is actually common in teenagers. Naturally, such a habit makes parent-teen cooperation difficult, especially when a parent wants his teen to do what a " responsible adolescent" would do. A poor decision-making teenager can never run away from his responsibilities. 1.
● Distinguish real problems from acts of pure "teenagerism". Teens often make poor decisions simply because they don-t have the experiences. By making small and harmless mistakes, like a recently- developed habit of careless consuming, a teen learns good decision-making skills on his own via self-correction.__ 2. Don't think the teen is making bad decisions just to challenge you. It's more likely it is out of a real inability to determine what's best for him.
● 3. Tell your teen you understand his decisions while simply emphasizing that you don't have to agree with his decisions or treat his views as valid. By not judging his opinions, tastes or style, you are opening the road for better communication and problem solving opportunities.
- Set clear expectations. 4. For example, if your teen refuses to study for his math final because "math is pointless," explain that you expect him to perform well in school, even in the "pointless" classes. Because you've already tolerated his opinion without trying to change his viewpoint, you two can easily agree that math isn't so useful, yet avoid saying "Let's just give up on math, then."
● Find a middle ground. Trade insignificant freedoms, such as clothing style for the promise that he'll live up to academic and family responsibilities. 5._ Not only does giving up a bit of control solve many conflicts, but the extra freedom you give him can also improve his decision-making.
A.Show tolerance.
B. Learn to solve problems.
C. Point out your expectations and his responsibilities.
D. If your teen could realize it, allow him to be himself.
E. A responsible adolescent must have role models to learn from.
F. Therefore, it’s important to guide them with problem-solving strategies.
G. Next time, he'll be more likely to think twice before making his buying decision.
