Treasure hunting(寻宝游戏) is not just a story from m{#blank#}1{#/blank#} or books, but can also be part of your next holiday.

Five years ago, US art collector and writer Forrest Fenn h{#blank#}2{#/blank#} a treasure box somewhere in New Mexico, the US. The box was f{#blank#}3{#/blank#} of gold coins, diamonds and other treasure. It's worth about ＄1. 8 m{#blank#}4{#/blank#} (12, 400,000 yuan), and it will go to whoever finds the box. The 84-year-old millionaire(百万富翁)7 l{#blank#}5{#/blank#} some clues(线索) in his book The Thrill of the Chase.

    Fenn said the i{#blank#}6{#/blank#} came to him after he got cancer(癌症) in 1988." I wanted the monetary value(金钱的价值) to be a consideration for those who are l{#blank#}7{#/blank#} for it, but mostly my motive(动机)was to get kids off the sofa and a{#blank#}8{#/blank#} from their texting machines and out in the m{#blank#}9{#/blank#} ."he told KOAT News in the US. Fenn said about 30,000 people came to find the box last year. He g{#blank#}10{#/blank#} that this year more than 50,000 people would come.

Most people around the world are right-handed. This also seems to be true in history. In 1799, scientists studied works of art made at different times from 1,500 B.C. to the 1950s. Most of the people shown in these works are right-handed, so the scientists guessed that right-handedness has always been common through history. Today, only about 10% to 15% of the world's population is left-handed.

Why are there more right-handed people than left-handed ones? Scientists now know that a person's two hands each have their own jobs. For most people, the left hand is used to find things or hold things. The right hand is used to work with things. This is because of the different work of the two sides of the brain. The right side of the brain, which makes a person's hands and eyes work together, controls the left hand. The left side of the brain, which controls the right hand, is the centre for thinking and doing problems. These findings show that more artists should be left-handed, and studies have found that left-handedness is twice as common among artists as among people in other jobs.

No one really knows what makes a person become right-handed instead of left-handed. Scientists have found that almost 40% of the people become left-handed because their main brain is damaged when they are born. However, this doesn't happen to everyone, so scientists guess there must be another reason why people become left-handed. One idea is that people usually get right-handed from their parents. If a person does not receive the gene (基因) for right-handedness, he / she may become either right-handed or left-handed according to the chance and the people they work or live with.

Though right-handedness is more common than left-handedness, people no longer think left-handed people are strange or unusual. A long time ago, left-handed children were made to use their right hands like other children, but today they don't have to.

    There are many online food shopping sites. Things l{#blank#}1{#/blank#}CDs, books, and DVDs sell well online. But it is quite different to sell food online because people like to see food with their o{#blank#}2{#/blank#} eyes. It is very I {#blank#}3{#/blank#} for people to buy fresh fruit and vegetables. Customers like to c{#blank#}4{#/blank#} their food by its color. They also want to touch and smell it. Some people like going to the same shop to buy food with good quality. So if the food is always g{#blank#}5{#/blank#}, they will feel comfortable buying it online.

    Boxes of fruits and vegetables have been d{#blank#}6{#/blank#} to homes around Britain for a few years now. Dried or canned foods are almost the same all the time, but fresh things are not. For example, People may want to pick their own apples so they can take the o{#blank#}7{#/blank#} that look nice. Buying dried and canned food online is easier. A person can buy this kind of food on the Internet and then buy fruits and vegetables at a store or a market.

    Students learn their lessons in class. In class, teachers teach them. Students sit in the classroom listening to the teacher. Is this the only way for students to learn? Of course not. There is another way to learn. That is, students can teach themselves. For example, if you cannot remember anything when you are doing your homework, you can look through（浏览） your book to find the answer. This is a way to teach yourself. And it's not a difficult thing. We can do it at any place and at any time.

    How to teach yourself? The first thing you must do is to read. Read something interesting. The second is that you must ask yourself questions. Many clever students often do this. The questions are about something you don't understand or you want to know more about. You can write down these questions. The third is to answer the questions yourself by thinking hard, by reading the texts or other books, and sometimes by asking other people. These are the ways of teaching yourself. And if you do these things for a long time, you can succeed（成功）in your study.

    Let me tell you something about sharks. Sharks are among the oldest animals in the world. There are over three hundred and fifty different kinds of sharks in the world. Most sharks are about two meters long and live in the oceans.

    A shark can smell something in the water, for example, the blood of animals. That helps them find their food. Sharks mainly eat fish, other sharks and plants in the ocean.

    Most sharks bite (咬)people by mistake. They think a person is a large sea animal. When the sun goes down or comes up, sharks are looking for food. So at these times people shouldn't go swimming in the ocean. Today people kill sharks for food and their skin. The number of sharks in the world is dropping fast.
