Question

【題目】 Whenever you walk past a cafe, you might be drawn in by the smell of freshly made coffee. But the minute you try this dark drink, you will regret it, because it tastes like bitter Chinese medicine.

Why does something that smells so good taste so bad? Many people are curious about this, but now scientists say they have found the answer – it lies in our “second sense of smell,”according to the Telegraph.

“We have two senses of smell,”explains Barry Smith, professor of the University of London. “One is when you breathe in things from the environment, and the other is when the air comes up the nose and is breathed out through the nose.”

When we drink coffee, for example, the act of swallowing(吞咽) sends a burst of smell up the back of our nose from inside the mouth. This wakes up the second sense of smell in our brain. But it is weaker and less sensitive to flavors(味道). As a result, it gives us a completely different feeling.

In fact, the second sense of smell plays a big part in our eating experience. It may be common sense that we smell through our nose and taste using our tongue(舌頭). But the truth is 80 percent of what we think of as taste actually reaches us through smell. Just hold your nose while eating and you will notice that your tongue can only catch a very small part of the favor.

【解析】

本文講述了一個例子：每當你走過一家咖啡館，你可能會被新鮮咖啡的味道吸引。但是一旦你嘗到這種黑飲料像苦味的中藥。這主要原因是第二嗅覺起作用。并介紹了第二嗅覺如何使我們有一種與第一嗅覺完全不同的感覺。

【1】考查細節(jié)理解。根據(jù)第3和4段可知我們有兩種嗅覺，一種是當你從環(huán)境中吸入東西，這是第一嗅覺，另一種是當空氣從鼻子上冒出來，通過鼻子呼出，這是第二嗅覺。你可能會被氣味吸引進來，這是因為我們的“第一嗅覺”起作用了；故選C。

【2】考查細節(jié)理解判斷。題意：以下哪項不正確？A. We have two senses of smell. 我們有兩種嗅覺；根據(jù)第3段“We have two senses of smell,”explains Barry Smith, professor of the University of London. 倫敦大學教授巴里史密斯解釋說：“我們有兩種嗅覺�！钡谝痪淇芍�A正確； C. The tongue can only catch a small part of the flavor. 舌頭只能抓住一小部分味道；根據(jù)第5段最后一句Just hold your nose while eating and you will notice that your tongue can only catch a very small part of the favor. 吃東西的時候，只要捏住鼻子，你就會注意到你的舌頭只能抓住一小部分的好處。可知C正確；D. We usually think we smell through our nose and taste using our tongue.。我們通常認為我們是通過鼻子來聞，用舌頭來品嘗；根據(jù)第5段第2句It may be common sense that we smell through our nose and taste using our tongue(舌頭). 我們用鼻子聞，用舌頭嘗，這可能是常識。可知D正確；B. The first sense of smell is weaker and less sensitive to flavors. 第一感覺氣味較弱，對味道不敏感；根據(jù)第4段“例如，當我們喝咖啡時，吞咽的動作會使我們的鼻子后部從嘴里發(fā)出一陣氣味。這喚醒了我們大腦中的第二種嗅覺。但對味道敏感度較低�！笨芍�第二感覺氣味較弱，對味道不敏感，故B錯誤；選B。

【3】考查細節(jié)理解。題意：哪一個身體部位在感覺味道時不起作用？A. The nose.鼻子；B. The tongue.舌頭；C. The eyes. 眼睛 ；D. The mouth.嘴巴。根據(jù)本文可知感覺味道的部位鼻子、嘴巴和舌頭，可知眼睛在感覺味道時不起作用；選C。

【4】考查詞意猜測。題意：第四段中下畫線單詞“sensitive”意思是____。A. reacting quickly反應迅速；B. reacting slowly反應緩慢；C. difficult困難；D. easy容易。根據(jù)下文As a result, it gives us a completely different feeling.（因此，它給我們一種完全不同的感覺。）可知此句But it is weaker and less sensitive to flavors句意是：但它比較弱，對味道不太敏感。根據(jù)句意可知“sensitive”意思是“reacting quickly”；故選A。

【5】考查主旨理解。本文講述了一個例子：每當你走過一家咖啡館，你可能會被新鮮咖啡的味道吸引。但是一旦你嘗到這種黑飲料像苦味的中藥。這主要原因是第二嗅覺起作用。并介紹了第二嗅覺如何使我們有一種與第一嗅覺完全不同的感覺。根據(jù)本文主要內(nèi)容可知這個故事最好的標題是第二嗅覺；故選B。
