【题目】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.

【2】Why have scientists been working on space elevators?

A. To make trips to space cheaper.

B. To help astronauts do research in space.

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.

Mountain biking is a great way to explore the outdoors, stay in shape, or just have fun. 【1】 Even though it’s dangerous, if you ride with caution, it can be enjoyed by the entire family.

Mountain biking can best be characterized into three different styles - downhill, free riding, and cross country. Even though the different styles are similar in some ways, they still require different skills. 2

Those just beginning will have to get past the bumps and bruises from falling off the bike.

The bike you select is more of a personal choice, and a big determining factor on the type of riding you will be doing. Bikes come in all styles, shapes, and prices, which will make selecting one for yourself very difficult indeed. 4 A great mountain biker will become one with his or her own bike. When buying, make sure you check for comfort, how it fits.

5 Anytime you are riding, you should wear a helmet, along with knee and elbow pads. If you are following a group or riding in the woods you should strongly consider a pair of goggles(护目镜) as well. Safety should be your top priority and never taken lightly anytime you are mountain biking.

E. It takes practice to succeed for a great mountain biker.

F. Before you buy a bike, always ask to try it out first.

G. The style that youpick will determine the type of bike you get.

【题目】Your weight has been important since the moment you were born. Maybe you even know what your birth weight was. Most newborns weigh between 6 and 9 pounds, but some may weigh more and some less. But very quickly, a baby gains weight and everyone is glad about that because it means the child is growing bigger and stronger.

As you get older, your weight is still important. It's something your parents and doctor will probably keep an eye on. When you go for a checkup, the doctor often will record your height and weight and compare it with what it was the last time you came in. The doctor wants to check whether you have a healthy weight because weighing too much or too little can be a problem.

But these days, being overweight is more common than being underweight. In the last 30 years, a growing number of kids and teenagers have developed weight problems. Today, 1 out of 3 kids and teens between the ages of 2 and 19 are overweight. Many grown-ups understand what it's like to have weight problems, since 2 out of every 3 adults (成年人) are overweight..wfsqzkss.

For kids and adults, weighing too much can lead to illnesses and health problems. And a kid who is overweight might be made jokes on or find it hard to keep up with friends on the playground. When people talk about being overweight, they mean that someone has more body fat than is healthy. Everyone has some body fat, but extra (多余的) fat can influence someone's health and ability to walk, run, and get around, as well as how the person looks and his or her self-respect.

now you have just about everything you need, except membership cards. these are very important and again you can spend a lot of time making them. 5 why not leave some space for a photo of yourself? that will make the membership card really look like it.

【题目】It was late one evening. I can’t remember what it was about, but my dad and I had a very big argument (争吵) when my mom was away. We both said things we didn’t mean, and in the end I said, “I’m leaving.” And he said, “Good. The sooner, the better.”

I threw a few things in a suitcase and closed the door angrily behind me, not knowing where I was going. After walking aimlessly for about 20 minutes, I stopped at a local supermarket. Then my phone rang. It was my mom calling. She said, “Hey, Mary. Where are you? Dad is worried about you.”

“How can he worry about me? I’ve been away for nearly half an hour, but he didn’t call,” I said with annoyance (烦恼). My anger returned and I remembered all the hateful things he’d shouted to me. “Listen, Mom. You can tell Dad that I’m fine. I’ll call you tomorrow,” I said and hung up.

I walked around the store, trying to get my thoughts together. By the time I paid for my purchases, it had been much later than I used to be out alone. When I left the supermarket, a large piece of white paper was in front of me. On the piece of white paper were these words: “Please come home! I miss you and I’m worried about you!”

Then a car pulled up beside me. Hanging out of the window was my dad. Beside him, smiling gently, sat my mom. And that’s when I started laughing. I laughed so hard that I cried. Despite (尽管) my best efforts to run away from home, my father finally managed to track me down. I couldn’t leave now, not with him sitting there with caring eyes.
