We talk about people being “colour-blind” but very few of us are. Even those who describe themselves as colour-blind are normally just colour lack. A strongly, colour-blind person will still be able to tell 20 different colours, 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 Colour-blind Island because so many people who live on this remote island can only sec in black and white.

Not being able to see in colour is bad enough. But one is lander, 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 colour-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 is Pingelap famous as?

A. A tiny island.

B. A beautiful island.

C. A mentally troubled island.

D. A colour-blind island.

2.What .can we infer about Herrol?

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

B. He is interested in burnt-out images.

C. He likes taking photos very much.

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

3.Why are about one-tenth of people in Pingelap seriously colour-blind?

A. Because Pingelap often suffers from tsunamis.

B. Because the king had an unlucky marriage.

C. Because the king’s genetic fault played a role.

D. Because the king made a serious mistake.

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

A. The island of colour-blindness.

B. The disadvantage of Herrol.

C. The history of Pingelap.

D. The advantage of colour-blindness.

During his school's “College Colours Day”, a fourth-grade boy in Florida, who dreams to become a student of the University of Tennessee, wanted to wear a shirt of the university, but he didn't have one. His teacher, Laura Snyder, suggested that he should wear an orange shirt to show his spirit.

When the day finally arrived, the boy was so excited to show his shirt-an orange one with a piece of paper attached to it, on which was his homemade design of the UT logo.

But by lunch time, the spirited fan was in tears. Some girls bullied (霸凌) him and made fun of his design that he had pinned to his shirt. Back to Snyder 's room, he put his head on desk and was crying, devastated.

In hopes of raising the boy's spirits, Snyder planned on buying him an official University of Tennessee T-shirt, and asked friends online if they had contacts with the university who could “make it a little extra special for him.”

The post immediately went viral and Snyder was contacted by the University of Tennessee informing her that they wanted to send the boy a care package of swag and apparel(服装) in support of him.

The story, however, didn't end here. The University of Tennessee said it was turning his “U.T.” design into an official T-shirt and had pre-sold more than 50,000 shirts online. The university won't profit from the shirts: It is donating the money to a charity dedicated to (致力于) getting rid of bullying of all forms.

“When I told him that his design was being made into a real shirt and people wanted to wear it, his jaw dropped," said Snyder. “He had a big smile on his face, walked taller, and I could tell his confidence grew!”

In recognition of the fourth-grader's spirit, the university has also extended an offer of honorary admission for him to join the Class of 2032. In addition, he has been awarded a four-year scholarship if he decides to attend UT in 2028 and meets admission requirements.

1.How did the boy react to his school's “College Colours Day”?

A.He prepared for it with a creative design.

B.He dreamed of winning a prize on the day.

C.He was afraid of being laughed at on the day.

D.He was shy of joining it without a university shirt.

2.How did the boy probably feel after lunch on the “College Colour Day”?

A.Excited and thankful. B.Confident and happy.

C.Shocked and sad. D.Nervous and worried.

3.What Snyder did for the boy shows that _________.

A.a strong will is vital to success

A study published Monday found that people who sleep less tend to be fat，and experts said it’s time to find out if more sleep will fight fatness.

“We’ve put so much emphasis on diet and exercise that we’ve failed to recognize the value of good sleep，”said Fred Turek，a physician at Northwestern University.

Monday’s study from Eastern Virgnia Medical School in Norfolk covered 1,000 people and found that total sleep time decreased as body mass index－a measure of weight based on height increased.

“Men slept an average of 27 minutes less than women and overweight and fat patients slept less than patients with normal weights，”it said.In general the fatter subjects slept about 1.8 hours a week less than those with normal weights.

“Americans experience insufficient sleep and fat bodies.Clinicians are aware of the burden of fatness on patients，”the study said.

“Our findings suggest that major extensions of sleep time may not be necessary，as an extra 20 minutes of sleep per night seems to be associated with a lower body mass index，”it added.

“We caution that this study does not set up a cause­and­effect relationship between restricted sleep and fatness，but investigations indicating success in weight loss via extensions of sleep would help greatly to set up such a relationship.”

The study was published in the Archives of Internal Medicine along with an editorial by Turek and Northwestern colleague Joseph Bass commenting on it and related research.

Inan interview，Turek said some studies have shown the lack of sleep causes declines in an appetiteholding back protein hormone，and increases in another hormone that cause a longing for food.“In addition neuropathies(神经疗法)in the brain governing sleep and fatness appear to overlap(部分重叠)，”he said.

“Fatness has been rising dramatically in developed countries and reached epidemic(流行病)levels in the United States，”it added，“leading to a variety of health problems.”
