As the weather gets warmer, there are few things that are better to do than travel. But traveling might not be that fun for those who have motion sickness (晕动症).
Motion sickness is also called travel sickness. It is a common experience for many people. Depending on how you travel, it can be called carsickness or seasickness. People with motion sickness feel very uncomfortable while they are in motion. They feel sick and dizzy (眩晕的), like the room around them won’t stop spinning.
It is generally believed that motion sickness happens when your senses become mixed up with each other, Scientific American reported. We use different parts of our body to sense movement. Our eyes tell us if we are moving. The inner ears (内耳) has a special liquid (液体) that helps us sense our direction and balance. Our muscles (肌肉) react to movement. When you move around, these body parts work well together. ________ Your inner ear signals that you’re moving, but your eyes say you’re sitting still because you can’t see that you’re moving. This mismatch gives us motion sickness.
But some people are less sensitive (易受影响的) to motion sickness. This may be because they have certain genes (基因) that prevent mismatching senses.
There are many ways to deal with motion sickness, but scientists believe that the key is to simply try and adapt to it. For example, some astronauts do special exercises that give them mild (轻微的) motion sickness. After a week or two, the astronauts become used to it and no more feel uncomfortable, Sam Puma, a NASA fight doctor, told the BBC.

【推荐1】Global warming is happening all around us. This experiment helps you learn how a greenhouse works, and how greenhouse gases influence (影响) the earth’s atmosphere (大气).
What You Need:
·Two thermometers (温度计) ·A notebook ·A pencil or pen
·A clear container ·A watch or clock ·A sunny area
What You Do:
1. Put the thermometers in direct sunlight. Let them sit in the sun for three minutes.
2. Draw two columns (栏), “Thermometer A” and “Thermometer B”, in the notebook.
3. After the three minutes, read and record the time and temperatures in the notebook.
4. Put one of the thermometers in the container and close it tightly.
5. Record the temperatures of the thermometers every ten minutes.
6. Discuss how the container influences the temperature.
What’s Going On?
The temperature outside the container is changing, as the warm air mixes with the passing cooler air. The air inside the container can’t mix with the air outside—it just gets warmer and warmer as the sunlight heats it up. A greenhouse works in a similar way: sunlight creates heat that can’t get out of the glass. And gases like CO₂ in the earth’s atmosphere act just like the glass in greenhouse, keeping the heat inside and making our world warmer and warmer.
1. What can you use to carry out the experiment?| A．a dark room | B．a paper box | C．some water | D．a glass bottle |
| A．To record temperatures at different times. |
| B．To record and compare the temperatures inside and out of the container. |

【推荐3】Are you the peace-loving type or the ambitious（有雄心的）go-getter? Your finger length might be a club. Take a look at your fingers. Would you believe me if I told you that the length of your fingers in relation to one another can predict your personality? I know that it sounds like one of those silly tests you see on: Facebook, but I have to admit that it is exactly correct for me. Here’s how it works.
Look at your three middle fingers of your hand. Is your index finger longer than your ring finger? Is your ring finger longer than your index finger? Or are the two of the same length? Find the situation that best matches your hand and see if what follows is an accurate description of your personality:
Longer ring finger: The Sweet Talker
If your ring finger is longer than your index finger, research shows that you’re likely 2 charming type, and you can probably talk yourself out of any situation. Others often find this personality type irresistible（不可抵抗的）, and you’re good at problem-solving. People in this category make great engineers, soldiers and crossword-puzzle（填字游戏）solvers.
Longer index. finger: The （Over） Confident One
If your index finger is longer than your ring finger, chances are you are full of confidence—possibly even 10 the point of being over-confident and proud. You are not necessarily introverted（内向的）, especially when you’re trying to complete a project. You are a dreamcatcher who can make things happen, but you may be shy when it comes to taking the first step in a relationship. You are also probably happy with what you have, but you’re always wishing for more.
Index and ring finger are of the same length: The Peacemaker
If your index finger and ring finger are of similar length, you are likely to avoid conic（矛盾）at all costs and seek to keep the peace in your relationships. You are well-organized, faithful and sympathetic. But deep down under all of that caring and peace-loving, you also have a hot-tempered side that can appear unexpectedly when you’re pushed too far. You will try your hardest to avoid a fight.
How well do these descriptions match your personality? I was surprised at the accuracy in my case. Why not check it out on your own. Maybe you will be impressed!

【推荐1】The spacecraft Shenzhou XIII carried Chinese astronauts Zhai Zhigang, Wang Yaping and Ye Guangfu to space. Many people may want to know about the three Chinese astronauts’ life in space. In fact, they could do many of the things as we do on Earth.
They brushed their teeth, washed their hair and went to the bathroom. However, because of the microgravity (失重) environment, they tended themselves in different ways. They washed their hair by using the no-rinse shampoo (免冲洗洗发剂) because there were no real showers in the spaceship.
Astronauts ate three meals a day: breakfast, lunch and dinner. But how much they ate depended on themselves. There were many kinds of food, such as fruits, nuts, chicken, beef and sea-food. They could also drink coffee, tea and orange juice.
Astronauts could have much fun too. They enjoyed wonderful sunrise which happened every 90 minutes. Astronauts could even spend weekends. They watched movies, played music, read books and talked to their families.
After a long day at work, nothing was better than a good night’s sleep. Astronauts had to sleep in sleeping bags in special cabins. Usually, astronauts were planned to have eight hours of sleep. Like on Earth, they might wake up in the middle of their sleep to use the toilet. And astronauts also had dreams.

【推荐2】Human bodies are amazing. Let’s look at one example first.
How can you tell whether something is hot or cold? You touch it. There are things in your fingers that help you to know whether something is hot or cold. They’re called nerves. You have them all over your body. Nerves react (作出反应)to things we touch and send a message to our brains, telling us how something feels.
If a knife cut your finger, how would that feel? It would hurt. If you didn’t have nerves, you wouldn’t hurt, but you would still bleed (流血). You wouldn’t be able to feel it. So, why are nerves a good thing? We would hurt ourselves a lot more without them.
Imagine that you’re making a snack in the kitchen. You put your hand on the cooker carelessly. After a minute or two, you notice so-me smoke rising in the air. Your hand is burning! If you had no nerves, you wouldn’t be able to feel the heat from the cooker. Your hand would hurt more seriously. Then you would have to go to hospital.
If we had no nerves, the weather wouldn’t make a difference to us. If it were below -40 degrees, you wouldn’t feel how cold it was. But if you went outside without protecting your body from the cold, you could get very sick or die. Nerves help us stay safe and healthy.
There are many other parts in our bodies that make us amazing.
1. Nerves send messages to people’s ________.| A．brain | B．skin | C．muscles | D．hands |
