Title: To be a {#blank#}1{#/blank#} student

    A study shows that one million lives might be saved each year if people wash their hands with soap(肥皂) often. It also says that hand-washing with soap could be among the best ways to reduce diseases. Doctors say many diseases can be prevented from spreading by hand-washing. These include the common cold, influenza(流行感冒), hepatitis(肝炎), infectious diarrhea(腹泻) and so on.

    Doctors say you are easy to catch a cold by touching your nose or eyes after someone nearby has sneezed or coughed. Another reason to catch a disease is to eat food prepared by someone whose hands were not clean.

    They also say that hand-washing is especially important before and after preparing food, before eating and after using the toilet, after touching money and sneezing or coughing. The most helpful way is to wash them together while using soap and warm water. You do not have to use special soap. Be sure to wash all areas of the hands for about ten to fifteen seconds.

Title : Basic Knowledge of hand-washing

    It is a fine Saturday morning. Bob and his family get up later than usual, because he isn't going to school and his father and mother aren't going to work. They are all staying at home, but they are not free. Each of them is doing a different thing.

    Bob's father is in the garage. He is washing his car. His mother is in the kitchen. She is busy preparing a good meal for the family. Sometimes, Bob helps his mum with the cooking, and sometimes he goes to the garage and watches his father wash his car. His elder brother, Jack, usually stays in his study till lunchtime. His two sisters are listening to some beautiful music while they're cleaning the house. His younger brother, Tom, is training his puppy. He is having a lot of fun. Around 12:30, the whole family is seated around the table enjoying a wonderful meal.

    Are you learning a foreign language? Do you know what a successful Language learner should do?

    First of all, successful language learners are independent(独立的) learners. They do not depend on books or teachers. They find out their own ways to learn the language. Instead of waiting for the teacher to explain, they try to find methods and rules for themselves. They also look for clues (线索)and get their own ideas by guessing(猜测). When they guess wrong, they try again. They try to learn from their mistakes. It is more important for them to learn to think than to know the meaning of every word.

    Successful language learning is active learning, so successful learners do not wait for a chance to use the language. They usually look for such a chance. They find native speakers and ask them for help when they make mistakes. They will try everything to communicate. They are not afraid to what they hear or to say strange things.

    Finally, successful language learners are learners with a purpose(目的).

    They want to learn the language because they are interested in native speakers' lives. It is necessary for them to learn the language in order to communicate with foreigners and learn about their lives. Their cultures and so on.

    Great white sharks in the Pacific Ocean. Wildebeest (角马)in Africa. Arctic terns(北极燕鸥) in the Atlantic. At first, these animals seem quite different. One swims, one walks, and the other flies. But they all have one thing in common, They all migrate(迁徙).

    Some migrating animals move to a place with a better temperature. Some go to find food or water. The groups travel as one, but during the trip, they face many different challenges.

    One challenge is distance. Some migrating animals take very long trips. For example, one great white shark swam from Australia to South Africa and back. In nine months, it swam about 20, 000 kilometers!

    Another challenge is finding enough food and water during the journey. For example, each Mali elephant needs over 200 liters of water each day. To get this, they need to go from one waterhole to another.

    Besides, migrating animals have to keep away from other animals that want to eat them. The zebra (斑马) has to avoid lions. Traveling as a group helps keep them safe. When one zebra is in trouble, the other members make a circle around it.

    By working as a group, migrating animals travel to live better lives.
