their pets.she wondered:“what if you could talk to your dog if you were gone?”working with her father in their garage,the 16-year-old came up with several ideas.finally,she invented a device that allowed pet owners to video chat with their pets!she calls the device icpooch.“the dog doesnt have to answer the call,”explains brooke.“it comes up immediately on the screen on its end.its a two-way audio and videoyou can see and hear each other.”with a click of a button you can even send the dog a treat!her invention has earned her a spot competing against nine other finalists in a young scientist competition for middle-school students.these finalists,selected based on their short video presentations,are working with mentors over the summer before heading to the final competition in st.paul,minn.after martins video put her among the 10 finalists in the discovery education 3m young scientist challenge,she was paired with delony langer-anderson,a product develop ment scientist in 3ms consumer health care division.“i just lead her down the product development path,”langer-anderson told livescience.this path includes guidance on how to test the potential product,which combines a video chat device that answers immediately on the dogs end with a dog treat device the owner can remotely activate.“one thing i have thought about a lot is,what happens if while the device is on the floor,what if your dog knocks it over,or scratches the screen?”martin said.she and langer-anderson discussed this,and martin is now testing materials at a local dog shelter by taping them to the dog house floor to see how well they withstand sharp teeth and claws.the finalists create models they can test,with the guidance from a mentor.their projects include a fuel cell that transforms cut grass into electricity and an app that rewards drivers for not texting or calling.langer-anderson tries to help the students work through the scientific method,testing their hypothesis,in a determined way.“so the kids dont get buried in data,”she said.5.which of the following would be the best title of the text?a.“icpooch” wins in a young scientist competitionb.a 16-year-old girl invents a device

everyone,including your family,friends,neighbors,and your former school teachers.is this something you can handle?1 if youre not worried about this,then youre ready!on the other hand,if you value your privacy and reputation intensely,reality tv stardom may not be for you.give it up before things get difficult if thats the case!2for a brand-new show,read whatever is already available in the media about the shows intended themes,content,time slot,and audience.3 this is probably easier if youve watched it without fail since it began.be practical.when you assess your suitability to go any further,some of the things that you should keep in mind include being realistic.it makes little sense to apply to be in a weight loss show when youre already at an ideal weight.4 if youre applying for a show wanting people with a business background or a college education and you dont have one,again,it may not be worth your while.know why you want to do this.the shows producers will want a strong,well-founded response.5 telling them “i want to be famous”rarely distinguishes you from every other person wanting the same.be confident in what you believe you can contribute to the show while focusing on your hoped-for outcome.a.can you actually sing,dance,act,etc.,as required?b.learn all that you can about the show before applying.c.do you mind if people who used to know you talk about you?d.nor is it wise to try modeling when your height isnt what theyre looking for.e.do you have to eat things that are simply awful and that youd never think of eating in a million years?f.give an answer that shows your strengths,your interesting points,and a desire to be a good role model.g.for an existing show,it makes good sense to be up-to-date about the entire show from its previous seasons.短文改错i once took part in a speech contest.such difficult was the topic that i completely had no idea about it.even a time for preparation was so limited.i felt hopeful and wanted to give up.and deep in my heart i didnt want to be a failure.so i recovered my courage and take the contest seriously.i kept remind myself,“if i try my best,i wont feel regretful,whichever the result is.”in the following days i struggled my goal.at the end,all my efforts paid off.i won first prize,which was much better than what i had expected it.导学号92550075#考点规范练38(选修8unit

sources.”及第二段内容可知,通过ibm的认知系统watson,olli可以与乘客互动。2.d推理判断题。根据倒数第三段中的“but driverless cars arent legal in every state.a company like fiat chrysler wont put out vehicles they cant sell everywhere,.”可知,由于无人驾驶汽车不是在每个州都合法,因此与谷歌合作的汽车厂商不会大规模生产无人驾驶汽车。3.b词义猜测题。根据倒数第二段中的“the company designed olli in 2015 and officially approved the project in march,2016.three months later,with ibm,they have a working vehicle in maryland.”可知,local motors从设计olli到上路只用了一年多的时间,由此看出,local motors“动作迅速”,堪为行业领头羊。4.c细节理解题。根据最后一段中的“.its a small company,so dont expect too many of them.”可知,由于local motors是家小公司,生产能力有限,因此不会有大批量的olli上市。【解题导语】本文介绍了一位16岁的中学生发明了一种远程照顾宠物狗的设备,并因此进入探索教育3m青年科学家挑战赛的前十名。5.d主旨大意题。本文主要讲了一位16岁的中学生发明了一种设备,这种设备能让狗和主人视频,让狗在主人离开时不感到焦虑,故选d项。6.a细节理解题。根据第二段第二句中的“.a device that
