在開始托福聽力備考之前，可能大家對托福聽力還缺乏一些基本的認(rèn)識，很多人對聽力的印象也許還停留在聽一段內(nèi)容然后答題的考試模式上。下面小編就和大家分享托福聽力備考辨音常見問題和能力訓(xùn)練要點(diǎn)分析 ,來欣賞一下吧。

托福聽力備考3大類核心常識介紹

托福聽力備考時(shí)間類常識介紹

針對托福聽力的練習(xí)時(shí)間知識，大家要明白托福聽力練習(xí)時(shí)間有兩個(gè)方面的理解，一是托福聽力練習(xí)時(shí)間點(diǎn)，二是托福聽力練習(xí)的時(shí)間長度。大家在托福聽力練習(xí)時(shí)間點(diǎn)上，提醒要盡可能的選擇上午的時(shí)間來練習(xí)聽力，原因在于托福聽力考試是托?？荚嚨牡谝粓隹荚?，同時(shí)還是在從上午開始。在托福聽力練習(xí)時(shí)間長度上，但并不建議大家使用太長時(shí)間但也不要太短，兩個(gè)小時(shí)左右最佳。對于這些時(shí)間只是也是我們要牢記在心的。

托福聽力備考語音類常識講解

新托福聽力方面語速是相當(dāng)快的，聽起來十分的模糊。但是事實(shí)上這不單單是語速快慢問題，最關(guān)鍵的是比如連讀、失爆、重音、弱化以及縮讀等美音里經(jīng)?？匆姷囊糇儐栴}?？忌胍档吐犃Ξ?dāng)中的阻礙，托福聽力練習(xí)時(shí)大家必須要掌握有的語音知識，才可以實(shí)現(xiàn)聽力能力的提升。如果把這些問題都解決了，想必托福聽力讀得再快、再模糊，大家同樣是可以“庖丁解?！?、反應(yīng)機(jī)敏。因此大家必須要注重語音知識的積累幫助同學(xué)們實(shí)現(xiàn)托福聽力高分。

托福聽力備考原則類常識解讀

托福聽力一般是在有限的時(shí)間里，要求大家把有效的句子及詞語抓住，如此不但需要靠實(shí)力同時(shí)還需要靠一些巧。在托福聽力的練習(xí)過程里，需要把四大原則掌握，才可以幫助大家降低托福聽力中的阻礙。這四大原則包括練習(xí)聽力的耐力，聽力的準(zhǔn)確性，對話題的敏感性和記筆記。利用這四項(xiàng)原則大家到了聽時(shí)不但能夠掌握文章的框架還可以抓住聽力中的細(xì)節(jié)。

托福聽力備考開始前考生需要了解的3大類核心常識就為大家介紹到這里，希望考生通過本文內(nèi)容明確托福聽力的備考方法和提分思路，順利完成備考實(shí)現(xiàn)高分目標(biāo)。

謝謝。見到你們這么多人對“生存在外層空間”這個(gè)系列感興趣真是太棒了。

Please excuse the cameras, we're being videotaped for the local TV stations.

請?jiān)忂@些攝像機(jī)，我們正在為地方電視臺錄像。

Tonight I'm going to talk about the most basic aspect of survival—the space suit.

今晚我將要談?wù)撽P(guān)于最基本的生存方面——宇航服

When most of you imagine an astronaut, that's probably the first thing that comes to mind, right?

當(dāng)你們中的大多數(shù)人想象一個(gè)宇航員的時(shí)候，那個(gè)可能是腦子里首先要想到的，對嗎?

Well, without space suits, it would not be possible for us to survive in space.

好，沒有宇航服，對我們來說生存在太空中是不可能的。

For example, outer space is a vacuum—there's no gravity or air pressure; without protection, a body would explode.

舉例來說，外層空間是一個(gè)真空空間——沒有重力和氣壓;沒有防護(hù)的話，人體將會爆炸。

What's more, we'd cook in the sun or freeze in the shade with temperatures ranging from a toasty 300 degrees above to a cool 300 degrees below zero Fahrenheit.

更重要的是，從酷熱的零上300華氏度到冰冷的零下300華氏度的溫度范圍里，我們會在陽關(guān)下被烤熟或者在陰影下被冰封

The space suit that NASA has developed is truly a marvel.

NASA研制出的的宇航服真是個(gè)奇跡

This photo enlargement here is a life-size image of an actual space suit worn by astronauts on the last space shuttle mission.

This part is the torso.

這個(gè)部分是軀干。

It’s made of seven extremely durable layers.

它是由七個(gè)極其耐用的層次制成的

This thick insulation protects against temperature extremes and radiation.

這個(gè)厚厚的隔離層防御了極端溫度和輻射。

Next is what they call a "bladder" of oxygen that's an inflatable sac, filled with oxygen, to simulate atmospheric pressure.

下一個(gè)是所謂的氧氣囊，那是一個(gè)可充氣的囊，充滿了氧氣，用來模擬大氣壓強(qiáng)。

This bladder presses against the body with the same force as the Earth's atmosphere at sea level.

這個(gè)囊狀物壓在皮膚上，帶著同樣的力量，就像地球空氣在海平面上一樣。

The innermost layers provide liquid cooling and ventilation.

最內(nèi)層提供了液體冷卻和通風(fēng)設(shè)備。

Despite all the layers, the suit is flexible, allowing free movement so we can work.

盡管有所有這些層，宇航服是有靈活性的，允許自由運(yùn)動，所以我們能夠工作。

Another really sophisticated part of the space suit is the helmet.

另一個(gè)非常復(fù)雜的宇航服的部分是頭盔

I brought one along to show you. Can I have a volunteer come and demonstrate?

我?guī)Я艘粋€(gè)過來展示給你們。我能找個(gè)志愿者過來演示一下嗎?

Don't worry, there's a boardwalk that goes across the marsh, so you can look down at the animals in the water from a safe distance.
