In most situations, light helps us see. But nowadays humans are using so much light that it is in fact a kind of pollution.
When it comes to looking at the night sky, too much light makes it d1.for us to watch some of life’s most wonderful views: stars, planets and even galaxies(星系).
According to scientific research, about 2,500 stars can be seen by the human eye without u2.any special equipment(设备). But because of light pollution, you can only see 200 to 300 stars from today’s countryside, and no more than ten stars from a city. In most big c3., people can’t see the sky filled with stars like they die in their childhood.
Light pollution influences more than just our view of sky. The latest research s4.that lots of nighttime light can harm wildlife too.
When birds fly to a5.place over cities, they sometimes get lost by the brightness and fly in circles u6.they drop from tiredness. Sea turtles need dark beaches for laying eggs, but they can’t find their ideal places because of those bright lights.
Too much light at night m7.even influence human health, but scientists aren’t sure of that. They are still learning more.
In order to prevent things from going w8., governments and some organizations are working to reduce light pollution. Many cities and towns have taken action to reduce the use of lights at night. Lights are used only when and where they are r9. needed.
Hopefully, in the near f10., humans can enjoy the clear and beautiful sky again and all the wildlife will live a peaceful and undisturbed life too.

It is easy for many people to catch a cold in the springtime or fall. It makes us wonder if scientists can send a man to the moon, why can’t they find a cure for the common cold? The answer is easy. There are actually different cold viruses out there. You never know which one you will get, so there isn’t a cure for each one.
When a virus attacks your body, your body works hard to get rid of it. Blood rushes to your nose and causes a block in it. You feel terrible because you can’t breathe well, but your body is actually eating the virus. Your temperature goes up and you get a fever, but the heat of your body is killing the virus. You also have a runny nose to stop the virus from getting into your cells(细胞). You may feel very uncomfortable, but actually your wonderful body is doing everything it can to kill the cold.
Different people do different things to deal with colds. In the United States and some other countries, for example, people might have chicken soup to help them get over the cold. Some people take hot baths. Other people take medicine to stop different symptoms(症状)of colds.
There is one interesting thing to note—some scientists say taking medicine when you have a cold is actually bad for you. The virus stays in you longer because your body doesn’t have a way to fight it and kill it. Bodies can do an amazing job on their own. There is a joke, however, on taking medicine when you have a cold. It goes like this:
It takes about one week to get over a cold if you don’t take medicine, but it takes only seven days to get over a cold if you take medicine.

Have you ever had the strange feeling that you were being watched? You turned around and, sure enough, someone was looking right at you!
Parapsychologists (灵学家) say that humans have a natural ability to sense when someone is looking at them. To research whether such a “sixth sense” really exists（存在）, Robert Baker, a psychologist (心理学家) at the University of Kentucky, did two experiments.
In the first one, Baker sat behind unknowing people in public places and stared at the backs of their heads for 5 to 15 minutes. The subjects(受试者)were eating, drinking, reading, studying, watching TV, or working at a computer. Baker made sure that the people could not tell that he was sitting behind them during those periods. Later, when he questioned the subjects, almost all of them said they had no sense that someone was staring at them.
For the second experiment, Baker told the subjects that they would be stared at from time to time from behind in a laboratory setting. The people had to write down when they felt they were being stared at and when they weren’t. Baker found that the subjects were no better at telling when they were stared at and when they weren’t.
Baker concludes that people do not have the ability to sense when they’re being stared at. If people doubt the outcome of his two experiments, said Baker, “I suggest they repeat the experiments and see for themselves.”

It feels like every time my mother and I start to have a conversation, it turns into an argument. We talk about something as simple as dinner plans and suddenly, my mother will push the conversation into World War III. She’ll talk about my lack(缺失) of a bright future because I don’t plan to be a doctor. And much to her disappointment, I don’t want to do any job related to science, either. In fact, when I was pushed to say that I planned to major(主修) in English and communications, she nearly had a heart attack.
“Why can’t you be like my co-worker’s son?” she bemoans all the time. Her co-worker’s son received a four-year scholarship and is now earning 70,000 dollars a year as an engineer. I don’t know what to answer except that I simply can’t be like Mr. Perfect as I’ve called the unnamed co-worker’s son. I can’t be like him. I’m the type of person who loves to help out in the community, write until the sun goes down, and most of all, wants to achieve a career because I love it, not because of fame (名声) or salary(薪水).
I understand why my mother is worried about my future major. I’ve seen my mother struggle to raise me on her small salary and work long hours. She leaves the house around 6:30 a.m. and usually comes home around 5 p.m. or even 6 p.m. However, I want her to know that by becoming a doctor, it doesn’t mean I’ll be successful. I’d rather follow my dreams and create my own future.

Anna was excited about starting her first day in the new school. However, when she first walked past the students in the school, her excitement turned to fear, and then to loneliness over the next few days. “Why didn’t anyone say ‘hi’ to me or invite me to his or her lunch table?

Almost every day during the first week, Anna stayed alone, thinking that there must have been something wrong with her or that nobody saw her at all!

When you smile at them, you are doing your best to show your kindness to them, and they are sure to understand that you are saying, “Hey, how’s everything going?” In this way, you are taking the first step towards the road to friendship.
When Anna realized this, she started talking to her classmates. Guess what happened? It really worked. She had made two friends by the end of the month.
