It was Christmas evening. I just 1home from the nearby grocery store with all kinds of things. The kitchen was2with brown bags and boxes. On seeing me coming back, my youngest son, Isaiah, reached me and 3 if I would play a game with him.
I took Isaiah's 4 . He stood there and his green eyes were5. “Here is a Christmas6 for you. Please find it. You can see something silver.” he said. I began to look for it. I 7 the table in the corner and some other places.
After a few seconds, I saw there was a 8 snow globe on the top of the piano. It was silvery and beautiful. I held the cool 9 in my hands.

Life-Changing Science Discoveries
Here's a look at some discoveries that have changed the world. It's impossible to rank their importance, so they're listed in the order they were discovered
Micro-organism
Before French chemist Louis Pasteur began experimenting with bacteria in the 1860s, people did not know what caused disease. He not only discovered that disease came from micro-organisms, but also realized that bacteria could be killed by heat and disinfectant(消毒剂). This idea caused doctors to wash their hands and disinfect their instruments, which has saved millions of lives.
Penicillin
Antibiotics are powerful drugs that kill dangerous bacteria in our bodies that make us sick. In 1928, British Alexander Fleming discovered the first antibiotic, penicillin, which he grew in his lab. Without antibiotics, infections like strep throat could be deadly
DNA
On February 28, 1853, James Watson of the United States and Francis Crick of England made one of the greatest scientific discoveries in history. The two scientists found the structure of DNA. Our genes are made of DNA and determine how things like what color hair and eye we'll have. In 1962, they were awarded the Nobel Prize for this work . The discovery has helped doctors understand diseases and may someday prevent some illnesses like heart disease and cancer.
X-rays
Wilhelm Roentgen, a German physicist, discovered X-rays in 1895. X-rays go right through some substances, like flesh and wood, but are stopped by others, such as bones and lead. This allows them to be used to see broken bones or explosives inside suitcases, which makes them useful for doctors and security officers. For this discovery, Roentgen was awarded the first-ever Nobel Prize in Physics in 1901.
One morning while Officer Vogel was on his coffee break in a restaurant, a man ran in a yelled. “Officer! A little kid is driving a car down the street!"
He ran out at once and saw a cargoing slowly--about 25 miles an hour--but it wasn't going very straight. He jumped into his police car and followed it. When the car was stopped, Officer Vogel looked inside. The driver was a little boy. His name was Rocco Morabiro and he was 5. In the back seat was his two-year-old sister. Both children were crying.
"I want my mummy!" the boy cried. "But she can't get here. I have the car.” Then he had an idea. "Just a minute." he told Officer Vogel. "I can drive. I'll go to get her.”
“No!" Officer Vogel said. “You stay with me!" Then he drove them to the police station and he called their mother. They had many questions for Rocco. The first question was: "Where did you get the car keys?"
Rocco said. “From the top of the refrigerator." At seven that morning Rocco's father was at work and his mother was sleeping, Rocco saw the keys on top of the refrigerator. He climbed up on a chair, and took the keys.
Rocco got into the car and started the engine. When Rocco's sister heard the engine, she ran to the car and cried. She wanted to go with him.
It was 7 a. m.—rush hour—so there was much traffic. Rocco drove one mile in heavy traffic. Then Officer Vogel stopped him.
Newspapers and TV stations heard about Rocco, and a lot of reporters went to his house. One reporter asked Rocco, “What do you want to be when you grow up?"
“A truck driver," he said, smiling.
Derek Rabclo is not the only surfer to conquer Hawaii' s famous Pipeline big wave break, but while all others use their sight to do it, this young professional surfer must rely only on his other senses. That's because he is completely blind.
When Derek was born, over 24 years ago, he got his name from Derek Ho, the first Hawaiian surfing world champion. A surfing enthusiast himself, Emesto dreamed that his son would share the talent of his uncle, a professional surfer. Unfortunately, Derek was born completely blind, but this didn't slop his family from believing lhat he could do anything he wanted, even if that meant becoming a surfer.
At age 2, Derek received a bodyboard and the beaches of Guarapari, Brazil, became his backyard. He was always comfortable in the water and surfing was in his blood, but he didn't actually try riding a wave until he turned 17, when his father bought him a surfboard. His father taught him the basics and encouraged him to keep practicing, but after successfully standing up on the surfboard, Derek knew he needed to become much better if he was going to achieve Emesto's dream and become a professional surfer. So he joined the Praia do Moroo surf school, where he studied under coach Fabio Maru.
Standing up on a surfboard and conquering small waves is one thing, while gathering the courage to take on Hawaii's board-breaking Pipeline is another. But that's exactly what Derek Rabelo set out to do just months after learning how to surf. Everyone told him it was too dangerous, but he felt he could do it. And he did, earning the praise of famous professional surfers like Kelly Slater and Mick Fanning. Now 24, Rabelo has been surfing the Pipeline every winter since.
Say you're sitting around with some friends playing video games and someone mentions a game that happens to be one of your favorites. “Oh, that game's easy. So not worth the time,” one of your friends says. The others agree. Although you enjoy the game quite a lot, not wanting to argue with them, you go along with the crowd.
You have just experienced what is commonly referred to as peer pressure(同伴压力), also called peer influence. You will adopt a certain type of behavior, dress, or attitude in order to be accepted as part of a group of your “peers”. As a teen, you are likely to have experienced the effect of peer pressure in a number of different areas.
We are all influenced by our peers at any age. For teens, as school and other activities take you away from home, you may spend more time with your friends than with your family. As you become more independent, your peers naturally play a greater role in your life.
According to Dr. Casey from Cornell University, teens are very quick and accurate in making decisions on their own and in situations where they have time to think. However, when they make decisions in the heat of the moment or in social situations, their decisions are often influenced by factors like peers. In a recent study, teen volunteers played a video driving game, either alone or with friends watching. The researchers discovered that the number of risks teens took more than doubled when their friends were watching, compared with when they played alone. This shows that teens may find it more difficult to controlrisky behavior when their friends are around, or in situations where they are extremely angry.
Just as people can influence us to make unwise choices, they can also influence us to make good ones. A teen might join in a volunteer project because his or her friends are doing it, or get good grades because his or her friends think getting good grades is important. In fact, friends often encourage each other to study, or try out for sports.
While we are always influenced by those around us, the decision to act or not is up to us. So when it comes to decision making, the choice is up to you.
When I was seven years old, I got the greatest Christmas gift ever.Now I realize I actually have the power to be a superhero. I may not able to fly, but I make a difference to someone's life. We all have the power to be a superhero to someone. Here are four ways you can be a real life superhero.
Think about what it is. It could be your support, time, advice, a small gift or a thank-you card. Sometimes, even just the most harmless message can bring someone out of darkness and into the light. It's something that you have to give that can help others.
Keep yourself healthy.Look after your body and helping people will be easier. You'll have a clear mind and energy to achieve any task in your way.
Pick your fight. Every superhero has a battle. It's something that drives them to be the person they are.It could be anything such as working towards helping reduce the number of homeless people on the street. The fight does not need to be big, but it needs to be powerful.
Make someone's day. Real life superheroes try to improve the lives of all the people they meet.You can also try your best to absolutely make someone's day every once in a while. The people who get your help will thank you for it.
A. What's your fight?
B. Stay happy all the time.
C. It was a Batman costume, complete with bell and shoes.
D. Use the things you have to help someone without them.
E. You can't be a superhero if you don't take care of your body.
F. They try their best to turn someone's bad day into a good one.
G. They just want to get up, save the world and forget it ever happened.
A rainforest is an area(cover) by tall trees with the total high rainfall spreading quite equally through the year. Rainforests have a great effectthe world environment because they can take in heat from the sun and adjust the climate. Without the forest cover, these areas would reflect (much) heat into the atmosphere, warming the rest of the world. Losing the rainforests may also influence wind and rainfall patterns, potentially(cause) certain natural disasters all over the world.
In the past hundred years, (human) have begun destroying rainforests in search of the three major resources: land for crops, wood for paper and other products, land for raising farm animals,affects the environment as a whole. For example, a lot of carbon dioxide in the air comes from burning the rainforests. People (obvious) have a need for the resources from cutting trees we will suffer much more than we will benefit.
Rainforests are often called the world's drug store. More than 25% of the medicines we use today come from plants in rainforests. However, fewer than 1% of rainforest plants have been examined for their (medicine) value. It is extremely likely that our best chance to cure diseases (lie)somewhere in the world's shrinking rainforests.
