【B1】______Many of these customs include stories and beliefs related to creatures, real or magical, taking the teeth. In Asia, for example, birds and other animals are thought to play a role in taking these baby teeth. In the West, though, a fairy is thought to visit. In all cases, it is considered lucky for the animal or fairy to take the offered tooth. 【B2】______Latter, the magpie will return and bring a new tooth for the child. This custom is also followed in other Asian countries. In both Japan and Vietnam, follow a similar tradition of throwing lost teeth onto the roofs of houses. 【B3】______In Mexico and Spain, for instance, tradition says a mouse takes the tooth and leaves some money. But in Mongolia, dogs are responsible for taking children’s teeth away. Dogs are highly respected in Mongolian culture and are considered to be people’s guardian angels. 【B4】______Accordingly, parents in Mongolia will put their child’s lost tooth in the fat of a piece of meat and feed it to a dog. 【B5】______Many children in Western countries count on the Tooth Fairy to leave money or presents in exchange for a tooth. The exact origins of the Tooth Fairy are unknown, although the story probably began in England or Ireland centuries ago. According to this tradition, a child puts a lost tooth under his or her pillow before going to bed. In the small hours while the child is sleeping, the Tooth Fairy takes the tooth and leaves something else under the pillow. What she does with the teeth is a mystery. In France, the Tooth Fairy leaves a small gift or candy. In the United States, however, the Tooth Fairy usually leaves money. These days, the rate is $1 to $5 per tooth.

When we think of good health, we almost always think about eating good food and doing exercise. However, getting enough sleep and dreaming are also part of good health. After a hectic day of work and play, the body needs to rest, and sleep is the body’s response to this need. Sleep is necessary for good health. During this time, the body recovers from the activities of the previous day. The rest that you get while sleeping enables your body to prepare itself for the next day.
There are four levels of sleep, each being a little deeper than the one before. When you sleep, your muscles relax little by little. Your heart beats more slowly, and your brain slows down. After you reach the fourth level, your body shifts back and forth from one level of sleep to another. Although your mind slows down, from time to time you will dream. Scientists who study sleep say that when dreaming occurs, your eyeballs move more quickly(although your eyelids are closed). This stage of sleep is called REM, which stands for rapid eye movement. Not only all humans, but all mammals have been shown to experience this REM stage. Dreaming is a normal and necessary part of a good sleeping pattern, but no one knows why we dream. If you have trouble falling asleep, there are a few possible ways of solving this problem. Some people recommend breathing very slowly and very deeply. Other people believe that drinking warm milk will help make you drowsy. There is also an old suggestion that counting sheep will put you to sleep!Questions 56—60 Complete the table with no more than three words from the passage.

问答题

Conventional wisdom says trees are good for the environment. They absorb carbon dioxide—a greenhouse gas—from the atmosphere and store it as carbon while releasing oxygen, a process for which forests have been called "the lungs of the planet". The roots of trees have been thought to trap sediments and nutrients in the soil. Trees have also been credited with steadying the flow of these rivers, keeping it relatively constant through wet and dry seasons, thus preventing both drought and flooding. It is all nonsense, concludes a research published this week. A four-year international study led by researchers at the University of Newcastle, in Britain, and the Free University of Amsterdam, identifies several myths about the link between forests and water. For example, in arid and semiarid areas, trees consume far more water than they trap. And it is not the trees that catch sediments and nutrients, and steady the flow of the rivers, but the fact that the soil has not been compressed. The World Commission on Water estimates that the demand for water will increase by around 50% in the next 30 years. Moreover, around 4 billion people—one half of the world’s population— will live in conditions of severe water stress, meaning they will not have enough water for drinking and washing to stay healthy, by 2025. The government of South Africa has been taking a tough approach to trees since it became the first to treat water as a basic human right in 1998. Trees lose water through evaporation(the technical term is transpiration)at twice the rate of grassland or South Africa’s unique fynbos scrubland. In a scheme praised by the hydrologists, the state penalizes forestry companies for preventing this water from reaching rivers and underground aquifers. In India, large tree-planting schemes not only lose valuable water but complicate the true problem identified by the hydrologists: the unregulated removal of water from aquifers to irrigate crops. Farmers need no permit to drill a borehole and, as most farmers receive free electricity, there is little economic control on the volume of water pumped. In the Kolar district in Karnataka, wells have dried up as the water table has plummeted from six metres to 150 metres below ground.

Trees have also been credited with steadying the flow of these rivers, keeping it relatively constant through wet and dry seasons, thus preventing both drought and flooding. It is all nonsense, concludes a research published this week. A four-year international study led by researchers at the University of Newcastle, in Britain, and the Free University of Amsterdam, identifies several myths about the link between forests and water. For example, in arid and semiarid areas, trees consume far more water than they trap. And it is not the trees that catch sediments and nutrients, and steady the flow of the rivers, but the fact that the soil has not been compressed. The World Commission on Water estimates that the demand for water will increase by around 50% in the next 30 years. Moreover, around 4 billion people—one half of the world’s population— will live in conditions of severe water stress, meaning they will not have enough water for drinking and washing to stay healthy, by 2025. The government of South Africa has been taking a tough approach to trees since it became the first to treat water as a basic human right in 1998. Trees lose water through evaporation(the technical term is transpiration)at twice the rate of grassland or South Africa’s unique fynbos scrubland. In a scheme praised by the hydrologists, the state penalizes forestry companies for preventing this water from reaching rivers and underground aquifers. In India, large tree-planting schemes not only lose valuable water but complicate the true problem identified by the hydrologists: the unregulated removal of water from aquifers to irrigate crops. Farmers need no permit to drill a borehole and, as most farmers receive free electricity, there is little economic control on the volume of water pumped. In the Kolar district in Karnataka, wells have dried up as the water table has plummeted from six metres to 150 metres below ground. Questions 71—75Complete the summary with a maximum of two words from the passage, changing the form where necessary. It is commonly believed that trees are good for the environment, as they absorb carbon dioxide and release oxygen: the roots of trees can trap water and【R1】______ the flow of rivers. However, a recent study has found that this belief is【R2】______. According to the research, trees lose【R3】______ water through evaporation than they trap. In South Africa, forestry companies are punished as the trees they planted prevented water from【R4】______ rivers and underground aquifers. In India, farmers drilled many wells and used the underground water to【R5】______their farmland. This has lowered water table to 150 metres below ground. Many trees have been planted and in fact these trees complicate the existing problem.【R5】
