2 . Find Your Adventure at the Space and Aviation(航空) Center
If you’re looking for a unique adventure, the Space and Aviation Center (SAC) is the place to be. The center offers programs designed to challenge and inspire with hands-on tasks and lots of fun.
More than 750,000 have graduated from SAC, with many seeking employment in engineering, aviation, education, medicine and a wide variety of other professions. They come to camp, wanting to know what it is like to be an astronaut or a pilot, and they leave with real-world applications for what they’re studying in the classroom.
For the trainees, the programs also offer a great way to earn merit badges(荣誉徽章). At Space Camp, trainees can earn their Space Exploration badge as they build and fire model rockets, learn about space tasks and try simulated(模拟) flying to space with the crew from all over the world. The Aviation Challenge program gives trainees the chance to earn their Aviation badges. They learn the principles of flight and test their operating skills in the cockpit(驾驶舱) of a variety of flight simulators. Trainees also get a good start on their Wilderness Survival badge as they learn about water-and land-survival through designed tasks and their search and rescue of "downed" pilot.
With all the programs, teamwork is key as trainees learn the importance of leadership and being part of a bigger task.
All this fun is available for ages 9 to 18. Families can enjoy the experience together, too, with Family Camp programs for families with children as young as 7.
Stay an hour or stay a week — there is something here for everyone!

3 . People have different ways of dealing with a common cold. Some take over the counter medicines such as aspirin while others try popular home remedies(治疗) like herbal tea or chicken soup. Yet here is the tough truth about the common cold: nothing really cures it.
So why do people sometimes believe that their remedies work? According to James Taylor, professor at the University of Washington, colds usually go away on their own in about a week, improving a little each day after symptoms peak, so it's easy to believe it's medicine rather than time that deserves the credit, USA Today reported.
It still seems hard to believe that we can deal with more serious diseases yet are powerless against something so common as a cold. Recently, scientists came closer to figure out why. To understand it, you first need to know how antiviral drugs work. They attack the virus by attaching to and changing the surface structures of the virus. To do that, the drug must fit and lock into the virus like the right piece of a jigsaw(拼图), which means scientists have to identify the virus and build a 3D model to study its surface before they can design an antiviral drug that is effective enough.
The two cold viruses that scientists had long known about were rhinovirus(鼻病毒) A and B. But they didn't find out about the existence of a third virus, rhinovirus C, until 2006. All three of them contribute to the common cold, but drugs that work well against rhinovirus A and B have little effect when used against rhinovirus C.
''This explains most of the previous failures of drug trials against rhinoviruses,'' study leader Professor Ann C. Palmenberg at the University of Wiscons in Madison, US, told Science Daily.
Now, more than 10 years after the discovery of rhinovirus C, scientists have finally built a highly detailed 3D model of the virus, showing that the surface of the virus is, as expected, different from that of other cold viruses.
With the model in hand, hopefully a real cure for a common cold is on its way. Soon, we may no longer have to waste our money on medicines that don't really work.

4 . A quarrel at home may result in you falling ill. Don't laugh, it's true. Family matters including living habits and even the way we speak have a big effect on our health, doctors say.
Wang Xiaoyu, a Senior 2 girl from Xichang, Sichuan Province, fainted (晕倒) in class when she heard her classmates quarrel at the top of their voices. Quarrels between her parents also put the girl into a coma. It is because she is suffering from depression , caused by bad relations at home, doctors explained."We don't get sick or stay well by ourselves," says Dr Robert Ferrer from the US. Ferrer shows that family forces may explain up to a quarter of health problems, in his recent research.
The genes you get from your family may cause illness. If one of your parents has a heart attack, your risk of being affected (影响) may double. But effects on health are not only written in our DNA.
Unrelated people who live under the same roof also get similar problems. Diet, lifestyle and environment affect our health, too.
Ferrer's research also found that if teenagers feel they are ignored (忽视) or unimportant at home they are more likely to get sick.
We may never fully understand all the effects that families have on our health. But just as individual problems can have effects on others, a small improvement can have big benefits , Ferrer said.
1. Which of the following can best explain why Wang Xiaoyu fainted in class?| A．Because her classmates often quarreled in class. |
| B．Because her parents used to quarrel. |
| C．Because of her depression caused by bad family relations. |
| D．Because her classmates shouted loudly at her. |
| A．We get sick or stay well by ourselves. |
| B．Only the genes we get from our family have a big effect on our health. |
| C．Our health has nothing to do with diet, life style and environment. |
| D．Teenagers who are ignored at home get sick more easily than those who are not. |
| A．embarrassment | B．faint | C．tiredness | D．sadness |
| A．Family relations. | B．The reasons why we get sick. |

5 . GPS has completely transformed how we get around. But other animals have long had their navigation (领航) systems built right in.
“We know their eyes are quite sensitive to polarized (偏振的) light and the sky has a particular pattern of polarized light relative to the position of the sun,” Barbara Webb, a researcher at the University of Edinburgh, says.
You can see polarized light firsthand if you take a pair of polarized sunglasses and spin them against the sky-the light passing through the glasses changes. Webb says the insects have polarization like that built into their many eyes. “You can think of it as having lots of sunglasses pointing in different directions.”
But Webb was curious whether there’s really enough information in the sky to give insects an accurate sense of direction. So her team built a sensor (传感器) modeled after a desert ant eye and put it under artificial light meant to simulate the sky. They then put that sensor into a model meant to model the brains of desert ants and other insects. And they found that with the insects’ sensing and processing equipment, they can likely sense direction down to just a couple degrees of error.
A system based on that of insects could someday be a cheap, low-energy choice to GPS. Insects have very tiny brains. A brain the size of a pinhead that’s using hardly any energy. And yet they’re still able to navigate better than we can with GPS, which is surprising. Webb is now working on building a robot that can use light to get its directions.

6 . For many parents, raising a teenager is like fighting a long war, but years go by without any clear winner. Like a border conflict between neighboring countries, the parent-teen war is about boundaries: Where is the line between what I control and what you do?
Both sides want peace, but neither feels it has any power to stop the conflict. In part, this is because neither is willing to admit any responsibility for starting it. From the parents’ point of view, the only cause of their fight is their adolescents’ complete unreasonableness. And of course, the teens see it in exactly the same way, except oppositely. Both feel trapped.
In this article, I’ll describe three no-win situations that commonly arise between teens and parents and then suggest some ways out of the trap. The first no-win situation is quarrels over unimportant things. Examples include the color of the teen’s hair, the cleanliness of the bedroom, the preferred style of clothing, the child’s failure to eat a good breakfast before school, or his tendency to sleep until noon on the weekends. Second, blaming. The goal of a blaming battle is to make the other admit that his bad attitude is the reason why everything goes wrong. Third, needing to be right. It doesn’t matter what the topic is—politics, the laws of physics, or the proper way to break an egg—the point of these arguments is to prove that you are right and the other person is wrong, for both wish to be considered an authority—someone who actually knows something—and therefore to command respect. Unfortunately, as long as parents and teens continue to assume that they know more than the other, they’ll continue to fight these battles forever and never make any real progress.

7 . When the young donkey Daisy May came to us，she was pregnant. With no donkey experience. I was unprepared for what might come next.
After some difficulty，Daisy’s baby was born. I thought the poor thing was dead. I planned to put the loss behind us and make sure she never got pregnant again. Just then，I heard a little noise. I couldn’t believe that baby was breathing and looking at me!We called him Samson，and of course I became his mother as much as Daisy was.
When Samson was nine months old，I had to separate Daisy and Samson for a few hours a day to wean(使断奶)him，but otherwise he went wherever she did. I think she would be lost without him. His donkey stepdad Bernard taught him to always be ready to have fun. They enjoy playing football together and going for a roll on a hot summer day.
I asked a worker to make a harness(马具)for my three little donkeys. When I brought it home I taught them one by one how to pull a cart. Samson watched and freely followed Daisy. When he was three，I put the harnness on him and he knew exactly what to do.
That was 15 years ago. Now，the most exciting thing about Samson is that he has become a little renowned. People come from all over to see him perform. The neighbors bring their grandchildren，and my sons bring their friends.
Samson shakes hands，unties my shoe，picks up a hat and more. And when I ask him if he has any bad habits，he tries to pick my pocket!He surprisingly learned these tricks himself. I just ask him to do them and he understands.
The relationship I have with my“baby”Samson has been an amazing experience. Every day is a fun day with this superstar donkey.

8 . Cassandra Warren, a baby-sitter, was in a rush and feeling a little overcome with work and planning her 200-person wedding. As she was getting invitations for her weddings in the mail one day last year, she hurriedly addressed one to her aunt and uncle in Oregon.
A week later, the invitation came back, with a handwritten note on the return envelope: “I wish I knew you. Congratulations! I’ve been married for 40 years—it gets better with age.” A $ 20 bill was inside.
Cassandra was at a professional crossroads and had been having a tough day. In fact, she nearly broke down, telling her husband-to-be, Jesse Jones, about her depression just as she opened the misdirected envelope. And the magic envelope wasn’t finished with its surprises. Cassandra looked closer and saw that on the envelope were “Live long and prosper”, a nod to space-based film Star Trek (《星际迷航》).
Casandra and Jesse have no idea who the anonymous note writer is. But they figure the Star Trek reference was because the person noticed the “fandom” corner of their invitation, which had both a Star Wars light-saber (光剑) and a Harry Potter wand (魔杖). “She assumed we’d understand her message,” Cassandra says. “Which we did.”
The following night Casandra and Jesse went out o dinner with a friend who was going overseas with the military. They happily put the $20 toward their bill. Then Casandra stopped by a store and bought another card—a thank-you card. She wrote her aunt and uncle’s incorrect address on the envelope again to “Kind Stranger.” Inside, she wrote, “Thank you for the note and taking the time to send it. Not many people would have done that. It was a big blessing after the day I was having. I am thankful for people like you still being in the world.”

10 . Sports can help you keep fit and get in touch with nature. However, whether you are on the mountains, in the waves, or on the grassland, you should be aware that your sport of choice might have great influence on the environment.
Some sports are resource-hungry. Golf, as you may know, eats up not only large areas of countryside, but also tons of water. Besides, all sorts of chemicals and huge amounts of energy are used to keep its courses （球场） in good condition. This causes major environmental effects. For example, in the dry regions of Portugal and Spain, golf is often held responsible for serious water shortage in some local areas.
There are many environment-friendly sports. Power walking is one of them that you could take up today. You don’t need any special equipment except a good pair of shoes; and you don’t have to worry about resources and your purse. Simple and free, power walking can also keep you fit. If you walk regularly, it will be good for your heart and bones. Experts say that 20 minutes of power walking daily can make you feel less anxious, sleep well and have better weight control.
Whatever sport you take up, you can make it greener by using environment-friendly equipment and buying products made from recycled materials. But the final goal should be “green gyms”. They are better replacements for traditional health clubs and modern sports centers. Members of green gyms play sports outdoors, in the countryside or other open spaces. There is no special requirement for you to start your membership. And best of all, it’s free.
