    When people use words and expressions different with the “standard language”, it is called an dialect. American English has many dialects. Even some parts of the USA, two people from neighboring towns speak a little different. American English has so much dialects because people have come from all over the world. Geography also plays a part in make dialects. Some people which live in the mountains of the eastern USA speak with an older kind of English dialects. When Americans move from one place to another, they took their dialects with them. Although many Americans move a lot of, they still recognize and understand each other's dialects.

    I am interesting in spiders (蜘蛛), so this summer I watched them for quite long lime. Spiders don't look beautifully, but they have their own way of killing flying insects. They often build “bridges” between branch. They climb up a branch slowly, pulling some silk. Then they pull the silk towards another branch. When they built many “bridges”, they begin to form webs. As long as insects happen to touch the webs, no matter what hard they try, they can't escape. One day, there was a stronger wind, and the webs were broken, but the spiders still went on to building their “bridges”. They are not afraid with difficulties. As students, we should learn from it.

    While the Greens went to the theatre, they left their German dog to guard his home. When two burglars broke into and the burglar alarm rang, the dog was waiting for them. Unfortunately, one of the burglars was dog-lover, and he quickly made friends with it. While the alarm was ringing, but the burglars were stealing cash and jewelry, worth over $10,000 from a safe, the dog lied down in its basket and went to sleep. When the police arrived at twenty minutes later, the burglars have gone. The dog was proud guarding the empty safe. When the first policeman entered the room, it immediately attacked him, tearing his trousers and bit him in the leg.

    When I look at this picture of myself, I realize of how fast time flies. I had grown not only physically and mentally in the past few years. About one month after this photo was took, I entered my second year of high school and become a new member of the school music club. Around me in picture are the things they were very important in my life at that time: car magazines and musical instruments. I enjoyed studying difference kinds of cars and planes, playing pop music, and collecting the late music albums. This picture often brings back to me many happy memories of your high school days.

    Questioning can lead to find an answer. If we are in habit of raising doubts as to if what we are told is true, we can find the correct answer and learn more.

    Two years ago, our teacher offered to us an answer to a difficult math problem in class. Although the answer seemed a little strangely, nobody but I doubted it . Thinking that my solution might be wrong, I carefully analyze the problem. Half an hour late, I managed to find the correct answer. When I showed my answers to him, the teacher praised me for my independent thinking.

    Questioning can serve as a bridge that help us to seek the truth.
