参考解析

解析:考查动词辨析。四个选项均有“花费”之意。spend“指花费时间、金钱、劳力等”,take“指需要占用空间、时间或精力等,其主语可以是人,也可以是事情”,cost“其主语是物,而不能由人充当,也不用被动形式”,expend“指为某一专门目的而花费大量金钱、时问或精力”。句意为“孩子们消耗很多能量,可能比成年人需要更多高能量的食物。”此处有很强的目的性,故选D。

Food is scarce and more often than not they go hungry. (英译汉)

BBreakfast is very important. It- s one of the most important meals of the day. To build strong bodies and keep healthy, everyone should always eat a good breakfast. Eating the right food is needed for good health. We may have eggs, bread, milk, etc.for our breakfast.Many fathers and mothers don-t get their children to eat breakfast because they don't have breakfast themselves. It-s bad for their health.Without breakfast children may not grow as fast as they should and may not study and play as well in school in the morning as they could. They can be often ill, and when they're ill, it may take them longer to be in good health again than it takes children with good health habits.Without food the body will stop working. Nobody will live without food.( )26.If we eat a good breakfast,________A. we’ll be happy in the morningB. we’ll make our bodies strong and keep healthyC. we’ll eat less for lunchD. we’ll pass the exam

AIf you go to a fast food restaurant.you will probably see a lot of teenagers. Today,many teenagers are overweight,and some of.this is because of their bad eating habits., Most teenagers love food with a lot of fat,oil,salt,and sugar. People often call this kind of food "junk food".But. bad eating habits go beyond fast food. We find many teenagers eat unhealthily. Some don't have breakfast before they go to school. During the day,some don't have a proper meal for lunch. In a recent survey at one school,scientists found that over two-thirds of the students didn't follow a healthy diet. They didn't like vegetables,and many of them didn't like to eat fruits. They preferred to eat food with a lot of salt,sugar,or fat.Parents today also worry about their children's diet. Some doctors give the .following ad-vice :★Teenagers shouldn't eat too much junk food.★ Teenagers shouldn’t eat food with too much salt. Salt can cause high blood pressure(高血压) in the future.★Teenagers should eat food with less fat,oil,and sugar.★Teenagers need to eat some fruits and vegetables every day: Fruits and vegetables arerich in vitamins(维生素 ) and have little fat.★Teenagers need to drink more milk. Milk will help their bones grow.★Teenagers need to eat breakfast every day. This is good for their body and mind.( )21."Junk food" contains(包含) a lot of ________.A. milk and sugarB. fruits and sugarC. vegetables and saltD. fat,oil,salt and sugar

单选题Passage1Children who spend more than two hours a day at a computer or watching television are more likely than others to have mental problems,scientists say.Researchers found that 11-year-olds who spent several hours in front of a screen each day did worse on mental health tests,no matter how much physical exercise they got. The University of Bristol study,published in Pediatrics,involved more than 1,000 children aged about 10.They also had the kids fill out questionnaires designed to gauge the kids' emotional well-being and behavior.The questionnaires contained 20 questions covering five sections-emotional difficulties,conduct problems,hyperactivity or inattention,friendships and peer groups and problems relating to friends and peer groups.The study found no direct evidence that sitting in front of a screen actually causes mental health problems. Instead,it suggests that children with difficulties,such as extreme shyness,are more likely to choose TV or computer games than sociable activities. In the study,children were asked whether they agreed,disagreed or somewhat agree with a list of statements,including,"I generally play alone or keep to myself" and,"I am often unhappy or tearful".They were also asked how much exercise they took and how long they spent at a TV or computer screen.According to the study,children who spent more than two hours a day at a screen had a 60% higher risk of mental problems than children who spent fewer viewing hours. The risk was only slightly higher in children who did little or no exercise."Physical activity is good for health in many ways,but it can't make up for long hours of screen viewing. Parents should consider limiting their children's screen viewing to no more than 2 hours a day,”said the study organizer,Angie Page.Previous studies have raised concerns that watching too much television can affect children's behavior in later life. A Canadian study found that those who watched most TV as young children performed worse at school, ate more junk food and had more trouble concentrating.How can children improve mental health according to the passage?ABy limiting TV and computer use to less than two hours a day.BBy getting more physical exercise.CBy playing more educational computer games.DBy going to bed earlier each night.
