Reading is a good habit, but the problem is that there's too much to read, and too little time to read every word of it. So ①we need to find good ways to read faster. There are hundreds of skills (技巧) to help you read more in less time. Here are two skills that I think are especially good.

Preview (预看) —if it's long and hard. This skill is especially useful for ideas of heavy reading like long magazine articles (文章) and business reports (报告).

    Here's how the preview goes.

●Read the first two paragraphs (段落) and the last two paragraphs carefully.

●Then read only the first sentence of the other paragraphs.

    This skill doesn't give you all the details (细节, 详情). It stops you spending time on things you don't really want or need to read.

    Skim (略读)—if it's short and simple (简单的). Skimming is a good way to get ideas of light reading like popular magazines or sports and entertainment (娱乐) papers.

    Here's how to skim.

    ●Get your eyes to move fast. Sweep across each line.

    ●Pick up only a few ②key words in each line.

    Everybody skims differently. You and I may not pick up the same words when we skim the same piece, but we'll get a similar (相似的) idea of what it's mainly about.

    Have you ever tried to hide your emotions (情感)from someone during a conversation? {#blank#}1{#/blank#}

    Scientists from the Ohio State University have found that people are able to tell other people's emotions according to changes in the color of their faces.

    Scientists studied pictures of people's facial expressions. {#blank#}2{#/blank#} For example, happiness makes our faces red around the cheeks and a little blue around the chin. Disgust(厌恶)creates not only a blue-yellow color around the lips, but also a red- green color around the nose and forehead.

    “We believe these color patterns are the result of small changes in blood flow triggered(触发) by the central nervous(神经) system." Lead researcher Alex Martinez said.

    {#blank#}3{#/blank#} Does the color alone or also facial expressions help people tell other's emotions?

    To figure this out, scientists added color patterns to pictures of faces that showed no facial expressions. {#blank#}4{#/blank#}They were able to tell the emotions 75 percent of the timewithout any difficulty.{#blank#}5{#/blank#} For example, when two people are heatedly arguing over something, we say they are red in the face. When a person is very angry, we'd say he or she is blue in the face.

        ①   In some Cultures, the foot of a rabbit is Carried as an amulet(护身符) believed to bring good luck. Belief is held in many parts of the world including Europe, China, Africa and South America.

       ②   Wishing upon a wishbone is an old Custom. It includes two people who would break the wishbone and the one with a Bigger piece makes a wish. The wishbone's shape just likes the letter" Y".

       ③   A In ancient days, old Boots or shoes were said to hold the good spirit and courage of their owners. Therefore, it was a Common Belief that an old Boot was a good luck Charm.

       ④   Clover is actually a type of wild plant with flowers shaped like Cotton balls and usually has three leaves on each stem. In fact, it is very difficult to find a four-leaf Clover.

    A city without cars would be very strange, right? But Venice is such a city.

    Venice is in the northeast of Italy. It isn't built on land, like Beijing or Shanghai, but on more than 110 islands. Seawater is everywhere around the city.

    Even so, travel isn't difficult. The waterways have always been the best way to get around. There are 117 waterways and more than 400 bridges that can lead you where you want to go.

    People in Venice move from place to place by boat. They like to enjoy cool summer nights while taking boat trips. They can talk to other people as they go along.

    Venice grew out of small islands in saltwater lakes when some Italians escaped(逃跑)from a war more than 1,500 years ago, and built homes there.

    Water makes the city special, but it is also a big problem.

    Once, people used too much underground water. This made the city get lower, little by little. Now the city has gone down by 23 centimetres.

    Another problem is the rising seawater. The temperature has risen over the years. This has made arctic(北极的)ice melt.

    Scientists are trying different ways to stop the city from getting even lower.
