    We have found plastic in the ocean and in animals like birds, fish and whales. But for the first time, scientists have found plastic in human poop (大便) , USA Today reported. The findings came from a study led by scientists from Environment Agency Austria {#blank#}1{#/blank#} The volunteers wrote down what they ate for a week and then provided a stool sample (大便样本) for testing.

    {#blank#}2{#/blank#}About 20 small plastic particles (IM) were found in every 10 grams (克) of stool. "The smallest plastic particles can enter the blood, the lymphatic system, and may even reach the liver (肝脏)," said Philipp Schwabl, who took part in the research. {#blank#}3{#/blank#}They're not sure how the plastic got in the volunteers' bodies, either. But most of the volunteers said they drank from plastic bottles and also ate seafood that could include plastic from ocean pollution.

    In fact, plastic is everywhere around us. Every year, lots of plastic waste goes into the ocean.{#blank#}4{#/blank#} Most of the particles stay in the ocean. Others can spread into the soil, and air. Could plastic in the air fall onto food and get into the human body?

    Some past studies may also give us a clue. {#blank#}5{#/blank#}And even some drinking water has been found to have tiny plastic particles in it.

    Summer is here. One of the best ways to cool off on a hot summer day is to jump into a swimming pool. Swimming is great exercise, and a trip to a pool or beach is a good way to have fun with friends. {#blank#}1{#/blank#}, so it's important to stay safe as you do it. Here are a few things you can do to swim safely.

    ●Swim only in areas set for swimming.

    Don't swim unless there is a lifeguard (救生员) on duty. If you're on a beach near the ocean, this is especially important. In some places, fast currents (急流) can sweep swimmers away without warning. So if a sign says "no swimming", please take care.

    Be careful when diving (跳水) into the water headfirst.

    Most pools have deep ends where diving is safe. In natural water, don't dive unless you know that the water is deep enough. {#blank#}2{#/blank#}, causing injury (伤害) or death.

    ●Make sure you have a partner with you.

    Nobody knows what will happen while you are swimming. If something goes wrong, you can get help from that person as soon as possible. In this situation, {#blank#}3{#/blank#}.

    ●Pay close attention to children's safety.

    Kids who don't know how to swim should wear life jackets. But by themselves they are not enough, {#blank#}4{#/blank#}. If you have a pool at home, put a fence (围栏) around it in case children fall in. And if a child disappears, check the pool first.

Huge Waves Destroying Arctic Ice Faster than Expected

    Ice covers much of the Arctic Ocean (北冰洋). Some pieces of ice are huge, like moving islands. As temperatures have increased, however, some of the ice has begun to disappear. Scientists have discovered huge waves (海浪) in the arctic waters.

    The waves were discovered by accident in May, 2010. Scientist Aleksey Marchenko and his students set out on a trip. They wanted to study the icy waters.

    On May 2, the ship traveled east and stopped next to a large chunk of ice around 50 miles from the small island of Hopen. Marchenko prepared to lead his students out onto the ice.

    "We were ready to go but when I went out, I discovered many cracks (裂缝) around," he remembers.

    He decided to move the ship deeper into the ice to keep safe. The farther in they went, he thought, the harder the ice would become. As they pushed forward, however, the ship experienced small waves, and then bigger ones. Soon, the waves broke up the ice around the ship into thousands of smaller pieces.

    Within an hour, Marchenko and his team saw a wave that was about 13 feet high. The ship's navigation (航行) system finally recorded the largest waves. They were more than 20 feet in height. The waves were so strong that they forced huge pieces of ice to jump up and down, breaking the ice into smaller pieces within just one hour. Scientists had never imagined that the process could happen so fast. The waves in these areas used to be small.

    The speed and force of the huge waves there makes it impossible to know in advance when they are coming. That could be dangerous for navigators and local communities who are unprepared for huge waves or depend on sea ice to protect them. Wildlife like polar bears and walruses that depend on sea ice to live is also in danger.

    Some scientists think people will soon see even bigger waves in these icy waters. As waves break up ice, the seas will become more open, and the waves will get even stronger. There are stormy times ahead.

    John is from London. He is 8 years old this year. His father is a waiter and his mother works on a farm. He is a pupil of Grade One.

    It's Monday today. Miss King is teaching them to count from one to ten. John is working hard in class. Soon he can count them. Miss King is very glad and asks him, "How many people are there in your family, John?" John stands up and says, "Two, Miss King." "Who are they?" "My father and mother." "Oh?" Miss King is surprised and says, "There are three people in your family." "But now I'm not at home. I'm at school, you know!"

    The professor always tried so hard. He had tons of brilliant ideas—but they never worked. Time after time, he would dream up an amazing idea that was sure to change the world—and then it didn't. {#blank#}1{#/blank#} "A time machine!" he shouted. The professor's dream wasn't just any old time machine. {#blank#}2{#/blank#} 

    But his wife wasn't so sure about the professor's great idea. "It'll never work. You can't make time," she doubted. The professor disagreed. "{#blank#}3{#/blank#} If you can make money and save money, why can't you do the same with time?"

In his workshop, the professor drew lots of plans for his new time machine. He soon lost track(轨道) of time. He created model clocks of every shape and size.{#blank#}4{#/blank#} Finally, he made an amazing discovery—a way to save time and give him lots of extra(额外) time. "I've got it!" he cried. "If I give up my time machine project, I'll have plenty of time for other things!"
