Frequently, we speak about people being ...

    Frequently, we speak about people being “color-blind” but very few of us are. Even those who describe themselves as color-blind are normally just color lack. A strongly, color-blind person will still be able to tell 20 different colors, compared to the 100 or so that normal-sighted people see.

Pingelap, a tiny island in the Pacific, is a beautiful spot but one that has a genetic trouble. It is known as Color-blind Island because so many people who live on this remote island can only see black and white.

Not being able to see colors is bad enough. But one islander, Herrol, who’s a fisherman, also struggles in full sunlight because all he sees is a painful burnt-out image. “I find it difficult to go outside in the sun,” he says, “because when it’s sunny I cannot see to do my work.”

But if being truly color-blind is rare, why is it that around 10% of the population of Pingelap live in a totally black and white world?

Well, we know that in 1780 the population of Pingelap was all but wiped out by a tsunami (海啸). As few as 20 people survived, one of whom was the king. It’s believed he had a genetic fault that causes colour-blindness and he passed this fault on to his many generations.

There is one advantage. Herrol can see well, really well, in the dark. So when it gets dark, Herrol and his friends get in their boats and hunt flying fish. They hang up flaming torches and the fish are attracted to the flames. “This type of fishing is fun,” Herrol says, “especially if we catch plenty. So even though it's hard work we enjoy it.”

1.What makes Pingelap special?

A. A mentally troubled island.    B. A beautiful island.

C. A colour-blind island.    D. A tiny island.

2.Which statement about Herrol is probably correct?

A. He doesn’t live in Pingelap any more.

B. He likes taking photos very much.

C. He is interested in burnt-out images.

D. He may stay at home when it’s sunny.

3.About one-tenth of people in Pingelap are seriously color-blind because ________.

A. the king’s genetic fault played a role

B. the king had an unlucky marriage

C. the king made a serious mistake

D. Pingelap often suffers from tsunamis

4.What would be the best title for the text?

A. The advantage of color blindness    B. The island of color blindness

C. The disadvantage of Herrol    D. The history of Pingelap

 

1. C 2. D 3. A 4. B 【解析】 这是一篇说明文。文章主要讲了太平洋上的一个小岛Pingelap,它被称为色盲岛,因为住在这个偏远岛屿上的很多人只能看到黑色和白色。 1.细节理解题。答案定位在第二段Pingelap, a tiny island in the Pacific, is a beautiful spot but one that has a genetic trouble. It is known as Color-blind Island because so many people who live on this remote island can only see black and white.可知,Pingelap岛的特别之处在于,在这个岛上居住的很多人都是色盲,故选C。 2.推理判断题。答案定位在第三段But one islander, Herrol, who’s a fisherman, also struggles in full sunlight because all he sees is a painful burnt-out image. “I find it difficult to go outside in the sun,” he says, “because when it’s sunny I cannot see to do my work.”可知,Herrol很难在阳光下出门,由此推断出天气晴朗时,Herrol可能待在家里,故选D。 3.细节理解题。答案定位在倒数第二段As few as 20 people survived, one of whom was the king. It’s believed he had a genetic fault that causes colour-blindness and he passed this fault on to his many generations.可知,在Pingelap,大约十分之一的人患有严重的色盲,因为当年国王的基因带有色盲基因,而他把这个基因传给很多后代。故选A。 4.主旨大意题。第二段Pingelap, a tiny island in the Pacific, is a beautiful spot but one that has a genetic trouble. It is known as Color-blind Island because so many people who live on this remote island can only see black and white.是全文的主题句,结合全文内容,可知这篇文章主要讲了太平洋上的一个小岛Pingelap,它被称为色盲岛,因为住在这个偏远岛屿上的很多人只能看到黑色和白色,故选B。

Not all English is the same

To many learners of English, it’s easy to think that all native speakers have no trouble communicating with one another.

1.

Well, it turns out that being a native English speaker from one country doesn’t mean that you’re able to perfectly understand a native English speaker from another country, and vice versa (反之亦然)

Take the UK and the US for example.

As a Briton, I grew up hearing American accents alongside British ones – on TV shows, movies and in songs.2. and how they would eat “cookies” instead of “biscuits”.  And it took me a while to figure out that the “trunk” (n. 后备箱) of a car is what us Britons call its “boot”.

The confusion didn’t stop at just vocabulary –3. For example, when talking about shopping malls, Americans pronounce it “mawl” instead of “mal”. And for some reason that’s hard for Britons to understand, Americans remove the “H” sound from “herb”, pronouncing it “erb”.

These small differences may not change much in a day-to-day conversation between a Briton and an American.4. Recently, for example, an American friend told me that she liked my pants. “You can see them?” I asked, shocked. Pants means “underpants” to most British people, which explains my horror.

5. In the US, for example, a “bum” is a homeless person, while the same word in the UK is used to describe one’s backside(n.臀部).

And, more amusingly, “trump” was only ever really used as a verb in the UK – meaning “to pass gas” – until the US’ current president came into the spotlight.

But as long as you can speak one version of English, it’s easy enough to understand any other – and any confusion just makes your day more interesting.

A. English is changing as it spreads around the world.

B. After all, English is English, isn’t it?

C. I soon noticed how Americans would put “gas” in their cars instead of “petrol” .

D. However, confusion can still happen every now and then.

E. There are different words that mean the difficult thing.

F. Some words can even be offensive (adj.无礼的) without you realizing it.

G. I discovered that many words are even pronounced differently.
