GRE考試與物理相關(guān)的詞匯
需要GRE考試的，大量練習(xí)詞匯是非常有必要的，下面是應(yīng)屆畢業(yè)生小編為大家分享有關(guān)GRE考試與物理相關(guān)的詞匯，歡迎大家閱讀與學(xué)習(xí)!
Heat Conduction熱傳導(dǎo)
原文：When a substance is heated, heat is passed from its hotter part to its cooler part. This way of passing heat is called conduction. Metals conduct heat easily. They are good conductors. Non-metals, such as wood, glass and plastic cannot conduct heat easily. They are bad conductors.
翻譯：物質(zhì)受熱時，熱量從溫度高的地方向溫度低的地方傳遞。這種熱的傳遞方式叫傳導(dǎo)。金屬容易導(dǎo)熱，是良好的導(dǎo)體。非金屬，如木頭、玻璃、塑料，不易導(dǎo)熱，不是良好的導(dǎo)體。
講解：上文中，substance是指物質(zhì)，物質(zhì)也可以用matter來表示。Conduct是傳遞、傳導(dǎo)的意思，做動詞時重音在后，讀作/ k?n?d?kt/，conduct的名詞形式是conduction，導(dǎo)體為conductor。導(dǎo)熱，可以說heat conduction，也可以用passing heat來表達。
Travel of Sound聲音的傳播
原文：Sound is produced when things vibrate, like beating a drum or beating a guitar.Sound has to travel through solid, liquid or air to ears. When the sound is blocked by other things, it become less loud and clear. Sound travels better through liquid that through air. It travels best through solid.
翻譯：聲音是通過震動產(chǎn)生的，例如敲鼓或彈吉他。聲音通過固體、液體或空氣傳入耳朵。當聲音被其他物質(zhì)阻擋時，聲音會變小、變得不清晰。聲音在液體中傳播比在氣體中傳播快，在固體中傳播最快。
講解：travel除了指旅行，也可以表示傳播，例如travel of sound聲音的傳播, travel of light光的傳播。第一句sound is produced when things vibrate是一個被動句，由be produced構(gòu)成被動結(jié)構(gòu);這句話中，vibrate的意思是震動。這段中三個關(guān)鍵詞為solid固體，liquid液體和air空氣。
Refraction of light光的折射
原文：Air, water and glass can let light pass through. They are called medium. When light passes from one medium to another, such as from water to air, its direction changes. This is called the refraction of light. The words under thick glass look higher up. The chopstick dipped into water looks bent. The rainbow looks curved. These are some examples of light refraction.
翻譯：空氣、水和玻璃可以使光通過，他們叫做介質(zhì)。當光從一種介質(zhì)傳播到另一種介質(zhì)，例如從水射入空氣，方向會發(fā)生變化，這一現(xiàn)象叫光的折射。厚玻璃下面的字看起來更高。浸入水中的筷子看起來彎曲。彩虹是彎的。這些都是光的折射。
講解：medium是介質(zhì)的意思，介質(zhì)是指能夠傳播能量的載體。Dip，浸蘸。Curve用作名詞是曲線的意思，curved為形容詞，彎曲的。
以上一些例子中，句子大多為簡單句，語言并不算難。我們可以看到，一些常見的詞匯，例如medium媒介，在物理學(xué)科中就成為了專有名詞。如果有相關(guān)的物理背景知識，還是很好理解的。有很多我們?nèi)粘Ｉ钪姓J識的詞匯，在科學(xué)背景的材料中似乎就變得難以理解了。這是因為我們欠缺相關(guān)的專業(yè)知識，不知道這個詞在這樣的語境下是什么意思。為了避免這種情況，需要多積累廣泛的背景知識，并在學(xué)習(xí)的時候充分調(diào)動起來。
