Are you lazy about brushing them? Never fear: An inventor is on the case. An electric toothbrush senses how long and how well you brush, and it lets you track your performance on your phone. The Kolibree toothbrush was exhibited at the International Consumer Electronics Show in LasVegas this week. It senses how it is moved and can send the information to an Android phone or iPhone via a Bluetooth wireless connection.The toothbrush will be able to teach you to brush right (don't forget the insides of the teeth！)and make sure you're brushing long enough. “It's kind of like having a dentist actually watch your brushing on a day­to­day basis，” says Thomas Serval, the French inventor.The toothbrush will also be able to talk to other applications on your phone, so developers could, for instance, create a game controlled by your toothbrush. You could score points for beating monsters among your teeth. “We try to make it smart but also fun，”Serval says.Serval says he was inspired by his experience as a father. He would come home from work and ask his kids if they had brushed their teeth. They said “yes，” but Serval would find their toothbrush heads dry. He decided he needed a brush that really told him how well his children brushed.The company says the Kolibree will go on sale this summer, for $ 99 to $ 199, depending on features. The US. is the first target market.Serval says that one day, it'll be possible to replace the brush on the handle with a brushing unit that also has a camera. The camera can even examine holes in your teeth while you brush.文章大意：本文主要講述了一種新式牙刷及其多種功能。1Which is one of the features of the Kolibree toothbrush?AIt can sense how users brush their teeth.BIt can track users' school performance.CIt can detect users' fear of seeing a dentist.DIt can help users find their phones.答案：A細(xì)節(jié)理解題。由第一段的第三句話可知，牙刷檢測刷牙的時間和好壞。故選A項(xiàng)。2What can we learn from Serval's words in Paragraph 3?AYou will find it enjoyable to see a dentist.BYou should see your dentist on a day­to­day basis.CYou can brush with the Kolibree as if guided by a dentist.DYou'd like a dentist to watch you brush your teeth every day.答案：C推理判斷題。根據(jù)第三段的It's kind of like having a dentist actually watch your brushing on a day­to ­day basis可知答案。3Which of the following might make the Kolibree toothbrush fun?AIt can be used to update mobile phones.BIt can be used to play mobile phone games.CIt can send messages to other users.DIt can talk to its developers.答案：B細(xì)節(jié)理解題。根據(jù)第四段的create a game controlled by your toothbrush可知答案。4What is Paragraph 5 mainly about?AHow Serval found out his kids lied to him.BWhy Serval thought brushing teeth was necessary.CHow Serval taught his kids to brush their teeth.DWhat inspired Serval to invent the toothbrush.答案：D段落大意題。根據(jù)第五段的第一句話he was inspired by.可知第五段主要講述了他制作牙刷的靈感。5What can we infer about Serval's children?AThey were unwilling to brush their teeth.BThey often failed to clean their toothbrushes.CThey preferred to use a toothbrush with a dry head.DThey liked brushing their teeth after Serval came home.答案：A推理判斷題。根據(jù)第五段孩子的假裝已刷牙，可知他們并不愿意刷牙。6What can we learn about the future development of the Kolibree?AThe brush handle will be removed.BA mobile phone will be built into it.CIt will be used to fill holes in teeth.DIt will be able to check users' teeth.答案：D推理判斷題。根據(jù)最后一段的The camera can examine holes in your teeth while you brush可知牙刷具有檢查功能。B(2013·安徽)Using too much water or throwing rubbish into our rivers are clear ways that humans can put our water supply in danger, but we also affect our water supply in less obvious ways. You may wonder how paving(鋪砌)a road can lead to less useable fresh water. A major part of the water we use every day is groundwater. Groundwater does not come from lakes or rivers. It comes from underground. The more roads and parking lots we pave, the less water can flow into the ground to become groundwater.Human activity is not responsible for all water shortages (短缺). Drier climates are of course more likely to have droughts (干旱)than areas with more rainfall, but in any case, good management can help to make sure there is enough water to meet our basic needs. Thinking about the way we use water every day can make a big difference, too. In the United States, a family of four can use 1.5 tons of water a day! This shows how much we depend on water to live, but there' a lot we can do to lower the number. You can take steps to save water in your home. To start with, use the same glass for your drinking water all day. Wash it only once a day. Run your dishwasher (洗碗機(jī)) only when it is full. Help your parents fix any leaks in your home.You can even help to keep our water supply clean by recycling batteries instead of throwing them away.文章大意：本文是一篇說明文。水是我們?nèi)粘Ｉ钪胁豢扇鄙俚?，但是你知道嗎？我們?nèi)粘Ｉ钪械囊恍┡e動，比如鋪砌道路和停車場，都有可能使我們的水供應(yīng)受到威脅。我們要從自身做起，幫助使我們的水供應(yīng)干凈清潔。7Which of the following is most likely to lead to less groundwater?AUsing river water. BThrowing batteries away.CPaving parking lots. DThrowing rubbish into lakes.答案：C細(xì)節(jié)理解題。根據(jù)第一段的“You may wonder how paving(鋪砌) a road can lead to less useable fresh water. .The more roads and parking lots we pave，the less water can flow into the ground to become groundwater .”可知，鋪砌道路和停車場會導(dǎo)致更少的地下水。8What can be inferred from the text?AAll water shortages are due to human behavior.BIt takes a lot of effort to meet our water needs.CThere is much we can do to reduce family size.DThe average family in America makes proper use of water.答案：B推理判斷題。根據(jù)第二段的第一句可排除A項(xiàng)；通讀全文可知，要想滿足我們的水需求，有很多事情要做，不是一件簡單的事情，需要花費(fèi)很多的努力，故B項(xiàng)正確；C項(xiàng)的family size錯誤；根據(jù)倒數(shù)第二段的“In the United States ，a family of four can use 1.5 tons of water a day! This shows how much we depend on water to live，but there's a lot we can do to lower the number.”可知，D項(xiàng)錯誤，普通美國家庭用的水是很多的。9The last paragraph is intended to _.Ashow us how to fix leaks at homeBtell us how to run a dishwasherCprove what drinking glass is bestDsuggest what we do to save water at home答案：D推理判斷題。文章最后一段主要講述在家如何節(jié)約用水，故選D項(xiàng)。10The text is mainly about _.Awhy paving roads reduces our waterBhow much we depend on water to liveCwhy droughts occur more in dry climatesDhow human activity affects our water supply答案：D主旨大意題。文章主要講述的是人類的活動如何影響水的供應(yīng)，A、B兩項(xiàng)只是文章的部分內(nèi)容；C項(xiàng)文章未詳細(xì)解釋。
