【解析】

本篇是科普知識,介紹冰在何種常態(tài)下溶解更快,由實驗可知熱量傳遞到冰塊的速度越快,冰塊融化的速度就越快。

1推理判斷題。根據(jù)題圖內(nèi)容可知本篇是冰在何種常態(tài)下溶解更快的實驗步驟,是物理實驗;故選D。

2推理判斷題。根據(jù)題圖The faster the heat transfers to the ice cubethe faster the ice melts …Heat transfers faster from warm water to the ice than it does from warm air and objects in the room to the ice… The foil makes it harder for heat to reach the ice.熱量傳遞到冰塊的速度越快,冰塊融化的速度就越快;從溫水到冰的熱量傳遞比從溫暖的空氣和房間里的物體到冰的熱量傳遞要快,鋁箔使熱量更難到達冰?芍窗谋鶋K在溫水中接受的熱量最快,融化得最快,故選B。

3推理判斷題。根據(jù)題圖“Try This …Write down your best guess and then try this experiment”可知文章的目的是為了鼓勵讀者做實驗;故選A。

本篇都考查推理判斷能力。解答前要先快速閱讀全文,理解大意;再閱讀題干,正確理解題干的要求;然后回歸原文,尋找有用信息作答;題1根據(jù)常識,判斷冰在何種常態(tài)下溶解更快的實驗是屬于物理實驗;題2要根據(jù)題圖的內(nèi)容——熱量傳遞到冰塊的速度越快,冰塊融化的速度就越快,據(jù)此來排除表述錯誤的選項,題3根據(jù)題圖的敘述推斷本文寫作意圖。

【題目】

When you imagine a new way of doing something and then find a way to do it, you are being creative. Generally, there are three steps to being creative. They are:

Step 1 Gaining knowledge and skills of how things are done

A solid knowledge and skills help you understand how to do something. Knowing when and how to apply this knowledge comes from studying how others have done things in the same situations. Think about learning to play the piano. In this step you learn how to read music and_______ the keys are on the piano. You also practise playing.

Step 2 Learning to_______ the way that people do those things

Practising how others do something will bring what you have learned and the practice of it together. Repeating other people’s skills will create a lot of _________ and increase understanding. So your next step in playing the piano would be seeing how other good musicians play, and repeating their songs and styles of playing.

Step 3 Exploring new and maybe better ways of doing them

Knowing the rules, but then using or breaking them in your_______ style is the basis of creativity. At this point in playing the piano, you might play songs in new ways; or even write songs and melodies (曲調(diào)). Being able to explore and improve on ideas requires time and effort to find out different ways of doing something.

Being creative is the useful ability to help solve problems effectively in many different situations. Being creative will often result in lots of ideas,_______ not all of them will be good ideas. That is why being creative is a process of trying - and trying again! Being able to come up with new ideas, and then_______ the better ideas, will make your life more successful. So start being creative today!
