A study says it is more dangerous than texting(发短信) while driving. Researchers found that there are more injuries(伤害) to texting walkers than there are to texting drivers. Their report says walking is not as easy as we think. We must focus on(专注) many things at the same time to walk safely in a straight line. The researchers said that people forget how to walk properly, so dangerous things happen to them. They run into walls and other people. They walk into cars, fall over things in the street, and even fall into holes or downstairs. A professor said walking is a difficult action. There are several reasons why texting makes walking dangerous. One is that people cannot see the street. Another is that they focus on their phones instead of their feet. A final reason is that their minds are somewhere else—they are not thinking about walking from A to B safely. The professor said over 6,000 people visited his hospital last year because of texting. He said the worst cases are head injuries. When a walker is tossed(抛) into the air, he or she has nothing to protect the head. The damage(损害) can be serious. 1.A study has found that .A.texting while walking is more dangerous B.texting while driving is safe for drivers C.walking is safer than driving when texting D.writing text messages in the house is dangerous 2.According to the study, in fact walking safely is A.very easy C.very useless B.very helpful D.very difficult .3.What will happen to texting walkers? A.They will walk safely in a straight line. B.They will run into walls and other people. C.They will do great harm to the passing cars. D.They will focus on many things at the same time. 4.How many reasons did a professor give for why texting makes walking difficult? A.One. B.Two.C.Three. Ⅳ.任务型阅读D.Four.阅读短文,并按要求完成 1~5 题。

His biggest dream was to find the best pond to 11 in freely without worrying about water snakes which were his natural enemies. One day, Froggie hopped(跨) to a kitchen and jumped into a pot full of hot water. Froggie felt the burning heat12 hurried out of water as fast as his legs could carry him, “I almost 13 there!” Froggie thought.A few days later, Froggie 14 back to the same kitchen, completely forgetting he had been there. He again jumped into the same pot. This time, the water inside was 15 . He 16 and thought, “There’s no water snake trying to eat me and I can have this place all to myself!” At that moment, Froggie knew it was his 17 pond. What he didn’t know was that the water was warming up over a low heat.After thirty 18 of swimming, Froggie felt the water was warmer but he regarded this as a nice surprise. “This is the best place for swimming. I get to have a hot bath, too.” 19 his comfortable bath, the water kept getting warmer and warmer. Froggie was so comfortable that he fell asleep. And he 20 woke up.From Froggie’s story, we can learn that people are blind to problems that slowly get worse over ti me.11.A.walk B.talk C.run D.swim12.A.and B.but C.or D.so13.A.slept B.fell C.died D.alive14.A.brought B.gaveC.wentD.put15.A.hot B.cool C.icy D.wet16.A.looked around B.looked backC.looked downD.looked after17.A.fish B.dreamC.swimmingD.skiing18.A.months B.days C.weeks D.minutes19.A.During B.Before C.After D.With20.A.soon B.often C.never D.alwaysⅢ.[2018·盐城]阅读理解Nature’s WarningsWhen the sky suddenly turns dark and the wind is strong, watch out! A dangerous storm might be coming. Storms are scary. Watch for flashes of lightning. Listen for thunder. If nature sends these warnings, don’t wait for rain. Act right away to keep safe.Safety StepsAt the first flash of lightning, quickly get inside a building or a car. Do not go into a shed(棚)for protection. It is not closed like a building, so it is not safe.Even after you are indoors, be careful. It is not smart to go near doors and windows. They can blow in or break. A room with no windows is the safest place to be.Do not wash your hands during a storm. Do not use anything that runs on electricity either. Water and electrical lines are like roads for lightning. Even if you really want to play computer games, don’t! It is better to be bored than to risk getting hurt. Try reading a book instead. Reading is more fun than playing computer games.If you can’t get to somewhere safe, stay out in the open. You may feel safe under a tree, but that is not a good place to be. Lightning is pulling toward t all poles and trees. Stay down in an open space and cover your ears to protect them. Loud thunder can damage your hearing.Lightning StrikesLightning does not strike people very often. It is not likely that you will ever see that happen. If you do, call 1-2-0. Only trained emergency workers should care f or a person who has been hit by lightning.If you follow these rules, you should stay safe during a storm.21.From Paragraph 1, we learn that .A.storms are frightening and harmfulB.storms often come without warningsC.people should wait and watch lightningD.people should take action after t he storm22.The underlined word “It” in Paragraph 2 probably means .A.a buildingB.a carC.a roomD.a shed23.During a storm you had better .e a computer for a whileB.listen for thunder by a windowC.leave the room and stay outD.find a closed or an open place24.If a person is hit by lightning, you should .A.call for emergency helpB.stay down in a safe spaceC.move him or her to safetyD.cover his or her ears quickly25.The best title for the passage is .A.Training StepsB.Home Rule sC.Natural OrderD.Storm SafetyⅣ.[2019·原创]词语运用根据短文内容及所给提示,在文中的空白处填写一个正确的单词。
