Question

【題目】A team of scientists from University of Freiburg in Germany are developing a shoe with a sensor to automatically tie its laces(鞋帶)that could be taken off when users click their heels together．

It’s been 26 years since we saw them magically tightening Marty McFly’s Nike boots in the film Back to The Future．

Now，self-tying shoelaces could actually become a reality this year，proving right one of the film’s fantastical predictions for what 2015 would be like．

Engineers have designed a shoe that can automatically lace up，adjusting itself to the shape of your foot．

Simply slip the controller on and pressure sensors will tell the ‘smart shoe’ when your foot is in position，triggering(觸發(fā))a tiny motor in the heel that pulls the laces tight.

When you want to take off the shoes，you click your heels together twice and the motor will release a spring(彈簧)in the shoe’s tongue，which loosens the laces enough for you to slip them off．

And the invention doesn’t even need to be plugged in to charge or have its battery replaced because it runs on power generated by the swing of your foot as you walk.

Engineer K1evis Ylli，of the Institute for Micromachining and Information Technology in southern Gemany，said the shoes could help a variety of different people.

“One focus is that it could be used in shoes for elderly people who have mobility problems，”he said．“But it could also work for children，or as a lifestyle product．”．

The design，which is still in a prototype(雛形)stage，cleverly gets the energy of the foot’s swing when opposing magnets in each shoe move past each other. It then uses that power to charge a battery．An hour of walking is enough to tighten the laces once，and it requires no energy to undo the shoes because that relies on the spring alone.

【1】Which of the following can be the best title of the text?

A. A fantastical prediction

B. A great invention in Germany

C. A shoe with self-tying laces

D. A popular lifestyle product

【2】What can we learn about the shoes?

A. They can automatically take off．

B. They can adjust themselves to your foot．

C. They need to be charged once．

D. They have been in design for 26 years．

【3】From the last paragraph we can know ____________．

A. the shoes have been put into use

B. the shoes need power to take off

C. the shoes promise to be popular

D. how the shoes work to produce energy

Answer 1

【答案】

【1】C

【2】B

【3】D

【解析】試題分析：德國工程師日前研發(fā)出一款智能鞋，不僅可以自己系帶，還可以自動根據(jù)腳型調整鞋子松緊。人們只需穿上這款鞋，安裝在鞋內的傳感器就會引發(fā)鞋底的小電機產生作用，束緊鞋帶。脫鞋時，將兩只鞋跟輕碰兩次，就會觸發(fā)鞋舌處釋放彈簧以松開鞋帶，使你脫下鞋子。

【1】C主旨大意題。A．A fantastical prediction一個空想的預測；B．A great invention in Germany德國的一個偉大發(fā)明；C．A shoe with self-tying laces 一種自綁鞋帶的鞋；D．A popular lifestyle product一種流行的生活產品；通讀文章可知，該篇文章主要講述的是：德國弗萊堡大學(University of Freiburg)的一個科學團隊正在研究一種可利用傳感器自動系鞋帶的鞋。故該題正確答案為C．A shoe with self-tying laces. 因為目前該產品正在研發(fā)中，所以排除B.D. 而根據(jù)文章細節(jié)所提到的：自動鞋帶今年可能真會成為現(xiàn)實，即可排除A.

【2】B細節(jié)信息題。由文章中的細節(jié)可知：當你想要脫鞋時，碰撞鞋跟兩次，發(fā)動機就會釋放鞋舌部位的彈簧，松開鞋帶讓你脫鞋。即可排除A. 且這項獨創(chuàng)性的發(fā)明甚至無需充電或更換電池，因為它僅靠你走路時雙腳的擺動來發(fā)電。即可排除選項C. 文中并沒提到該項研究的開始時間，所以D也錯誤；而根據(jù)文章中的Engineers have designed a shoe that can automatically lace up，adjusting itself to the shape of your foot．（工程師們設計出一款鞋可以自動系鞋帶，并可根據(jù)腳型自動調節(jié)。）可知，該題正確答案為B.

【3】D細節(jié)推理題。根據(jù)文章最后一段可知，目前，這項設計還是雛形。即可排除A. 解鞋帶時只需依靠彈簧，因此無需能量。即可排除B. 也沒提到它一定會流行，即排除C. 而其提到的：當兩只鞋中極性相反的磁鐵互相移動時，設計師能巧妙地獲得能量。然后將這些能量給電池充電，走一個小時的路，產生的電量足以系緊一次鞋帶。由此可知，這種鞋是如何產生能量的。
