Is there the best time to sleep? Actually, you have an amazing biological clock (生物钟) inside your body which can tell you some true facts.
From 11 p.m. to 3 a.m, your liver (肝脏) gets larger when filled with more blood and it lets the rubbish in your body out. If you go to sleep at 11 p.m., you have 4 hours to clean up the rubbish. And if you sleep at 2 a.m, there is only an hour to go. What if you sleep after 3 a.m.? Unfortunately, you won’t have any time to clean yourself. If you continue with this sleeping habit, there will be more toxins (毒素) in your body. You know what will happen next.
What if you go to bed late and wake up late? Did you realize you felt very tired the next day no matter how much you slept?
Going to bed late is very bad for your health. Besides not having enough time to clean your body, you will miss other important body functions (功能), too.
From 3 a.m. to 5 a.m., you should exercise and breathe in fresh air to take in good energy into your body. From 5 a.m. to 7 a.m., go to the toilet. And from 7 a.m. to 9 a.m., it’s the best time to have breakfast. This is your most important meal in a day. Not having breakfast causes lots of health problems for you in the future.
Once you know the importance of your biological clock, try your best to follow it. What if you have much work to do until late at night? Well, why not go to bed early and wake up early to do it? You’ll get the same time, but your body will get fit.

【推荐3】Many people dream of travelling into outer space. However, spending too much time in space may cause health problems, according to NASA. That’s why astronauts shouldn’t spend more than six months on the International Space Station (ISS) at a time.
Muscle (肌肉) and bone (骨头) less
In a weightless environment, astronauts don’t need to use their muscles to support themselves. Therefore, their muscles start shrinking (萎缩). To keep their muscles strong, astronauts need to exercise about 2 hours each day on the ISS. The weightless environment also causes astronauts’ bones to lose minerals (矿物质), with density (密度) dropping at over 1 percent per month.
Sleep disorder (混乱)
In space, the sun rises every 90 minutes. It is hard for astronauts to get used to this light-dark cycle when they sleep. Also, they need to sleep in a sleeping bag that is fixed to a wall, which is uncomfortable. Astronauts now have individual sleeping pods (分离仓) that help shut out some of the light. Still, studies have found that most astronauts only sleep about six hours each night, even though they should have eight and a half hours. Brain changes scientists have found that the position of the brain changes during spaceflight. It shifts upward within the skull (头骨). This can affect how the brain deals with how we see, stay balanced (平衡) and move around. That’s why some astronauts can’t control (控制) their movement and balance after returning to the Earth.
Scientists have also found that astronauts may get used to this change after going on more spaceflights. But they still need to do more research.

【推荐2】“Volunteering makes you look at the world differently. You can also see how little things can change a person’s life for the better, which makes everyone a better person.” Mason, a volunteer said.
National Volunteer Week started in 1974 and is held every April. It is a time to thank volunteers for their achievements. It is also a perfect opportunity(机会)to encourage others to take their first step toward becoming a volunteer. Making the decision to take the first step can be the biggest problem, because they often wonder if they will be able to meet the organization’s expectations. Some people fear not knowing anyone else in the group. Not having enough time also prevents some from sharing their abilities.
The following tips can help if you have some of these worries.
★ Start out slowly, don’t add too much pressure. Even a few hours a month can make a big difference in someone’s life.
★ Choose an organization with the same interests and common values.
★ Take part in a training meeting for new volunteers, even if it is not asked.
★ Work with a veteran volunteer. He volunteered a lot, he can help you increase the confidence (自信) and completely understand the organization’s expectations.
★ Invite a friend or family member to serve. It is a good experience to volunteer with them.
★ Finally, it is most important to enjoy the volunteer experience and to remember that not all volunteer experiences are perfect. If one experience doesn’t work, don’t give up and you’ll surely find the right opportunity.
Spend some time on volunteer work and you will see great changes in people’s lives. As Mason discovered during his volunteer experience, “little things can change a person’s life for the better.”

Mr. Malone replied. “I’ve talked to you about your lateness. I am afraid you won’t be able to go with us in the field trip.”“But…” Julia cried. Mr. Malone stopped her. “Unless your parent comes in to discuss this with headmaster and me, you won’t be attending. ”
After dinner, Julia found the courage to talk to her dad. She told about the messy science tables and how her science teacher would deduct(减去)points from their daily grades if they did not clean up. Her friends’ next class was on the opposite side of the building. Since her class was nearby, Julia volunteered to help clean up so that her friends would not be late. Then she explained how this would prevent her from attending the school trip . Her dad watched her for several seconds. Finally, he simply said, “I’ll be there right after school.”
The next day after school, Julia walked to the office. Her father and Mr. Malone were already there. Mrs. Thompson, the headmaster, spoke, “Julia, why were you cleaning the science tables alone ?”
Julia answered slowly,“I guess no one wants to clean up, and I don’t want my friends to get into trouble. ”“But you got yourself in trouble. ”Mrs. Thompson said. Julia nodded. Julia’s dad continued, “You’re still responsible for breaking the rules; even if it was for a good reason. Do you have any ideas for a punishment ? ” Julia shook her head hopelessly.
“Normally, your lateness would prevent you from attending some school activities. However, I have considered the reason and will allow you to go on the trip.” Mrs. Thompson said. Julia jumped out of her seat, repeating, “Thank you, thank you, thank you !” “Don’t be too excited. You’ll have a one-day detention (课后留校) for each lateness.” Mrs. Thompson warned, “I hope you won’t be late again.”
“No, madam, I won’t.” Julia replied, smiling from ear to ear.

【推荐3】Traveling can be expensive. But there are some ways to save money when traveling. Try some of the advice below on your next vacation and your wallet will thank you.
Look for city tourism cards. With the card, you can pay less at restaurants and shops. You don't have to wait for a long time at busy attractions. You might even get free tickets to top tourist attractions. City tourism cards can save your money and time without question.
Don't get the best room. How long will you stay in your room? Will you just be sleeping there? Do you really need a bigger room with a good view (景色)?
Find a hotel outside a city. It can help you save some money by choosing a hotel away from big tourist attractions, for you are always doing the same—go to the attractions and then return to your hotel to sleep.
Book (预订) a room with a kitchen. Although some people might not like to cook while on vacation, I don't mind making breakfast in my room. We always eat at a nice restaurant on our last night of the vacation. I'd rather eat breakfast and lunch at the hotel and then spend much money on a delicious supper.
