Question

Sports shoes that work out whether their owner has done enough exercise to promise time in front of the television have been devised in the UK.

The shoes- named Square Eyes- contain an electronic pressure sensor and a tiny computer chip to record how many steps the wearer has taken in a day. A wireless transmitter (發(fā)射器) passes the information to a receiver connected to a television, and this decides how much evening viewing time the wearer deserves(應(yīng)得), based on the day's efforts.

The design was inspired by a desire to fight against the rapidly ballooning waistlines among British teenagers, says Gillian Swan, who developed Square Eyes as a final year design project at Brunel University in London, UK. "We looked at current issues and childhood overweight really stood out," she says. "And I wanted to tackle that with my design."

Once a child has used up their daily allowance gained through exercise, the television automatically (自動地) switches off. And further time in front of the TV can only be earned through more steps. Swan calculated how exercise should translate to television time using the recommended daily amounts of both. Health experts suggest that a child take 12,000 steps each day and watch no more than two hours of television. So, every 100 steps recorded by the Square Eyes shoes equals exactly one minute of TV time.

Existing pedometers(計(jì)步器) normally clip onto a belt or slip into a pocket and keep count of steps by measuring sudden movement. Swan says these can be easily tricked into recording steps through shaking. But her shoe has been built to be harder for lazy teenagers to cheat. "It is possible, but it would be a lot of effort," she says. "That was one of my main design considerations."

A．keep a record of the steps of the wearer.

B．deal with overweight among teenagers.

A．sends teenagers' health data(數(shù)據(jù)) to the receiver.

B．counts the wearer's steps through shaking.

C．records the sudden movement of the wearer.

試題分析：本文主要介紹了一款智能運(yùn)動鞋，通過利用孩子們每天走步數(shù)來決定看電視的時(shí)間，起到控制體重的作用。

1.推斷題。根據(jù)第三段"We looked at current issues and childhood overweight really stood out," she says. "And I wanted to tackle that with my design."可以推斷這個(gè)設(shè)計(jì)是為了解決孩子超重的問題。

2.推斷題。根據(jù)第四段 Once a child has used up their daily allowance gained through exercise, the television automatically switches off. And further time in front of the TV can only be earned through more steps.說明這種鞋子利用走路的步數(shù)來控制孩子看電視的時(shí)間

3.推斷題，根據(jù)最后一段 Swan says these can be easily tricked into recording steps through shaking. But her shoe has been built to be harder for lazy teenagers to cheat. "可知得知其他類似的產(chǎn)品可以通過晃動來作弊，但她設(shè)計(jì)的鞋子使懶惰的青少年很難作弊

4.主旨大意題。本文主要介紹了一款智能運(yùn)動鞋，通過利用孩子們每天走步數(shù)來決定看電視的時(shí)間，起到控制體重的作用。

考點(diǎn)：科普性說明文。

點(diǎn)評：本文是一篇科普性說明文。科普說明文是以介紹科學(xué)技術(shù)、普及科學(xué)知識為目的的說明文體，主要通過對有關(guān)事物的介紹或事理的闡釋，讓讀者獲得知識、信息，對說明對象有所了解，并獲得某些方面的啟示題材涉及范圍較廣。做這類題時(shí)，要通讀全文，弄明白短文講的是什么，理解文中的具體信息和概念，結(jié)合上下文句子，理解文意。然后，抓住原文重點(diǎn)詞，結(jié)合語法和詞義，進(jìn)行歸納，演繹，推理。注意首段和各段第一句話，將其含義連接成一個(gè)整體；不要一看首段有問題相關(guān)問題就忙于選擇答案。
