【题目】B

It happened to me recently. I was telling someone how much I had enjoyed reading Barack Obamas Dreams From My Father and how it had changed my views of our President. A friend I was talking to agreed with me that it was, in his words, a brilliantly written book”. However, he then went on to talk about Mr. Obama in a way which suggested he had no idea of his background at all. I sensed that I was talking to a book liar.

And it seems that my friend is not the only one. Approximately two thirds of people have lied about reading a book which they haven’t. In the World Book Day’s “Report on Guilty Secrets”, Dreams From My Father is at number 9. The report lists ten books, and various authors, which people have lied about reading, and as I’m not one to lie too often (I’d hate to be caught out), I’ll admit here and now that I haven’t read the entire top ten. But I am pleased to say that, unlike 42 percent of people, I have read the book at number one, George Orwell’s 1984. I think it’s really brilliant.

The World Book Day report also has some other interesting information in it. It says that many people lie about having read Jane Austen, Charles Dickens, Fyodor Dostoevsky (I haven’t read him, but haven’t lied about it either) and Herman Melville.

Asked why they lied, the most common reason was to “impress” someone they were speaking to. This could be tricky if the conversation became more in–depth!

But when asked which authors they actually enjoy, people named J. K. Rowling, John Grisham, Sophie Kinsella (ah, the big sellers, in other words). Forty-two percent of people asked admitted they turned to the back of the book to read the end before finishing the story (I’ll come clean: I do this and am astonished that 58 percent said they had never done so).

【题目】Carrot juice, because of its many healthy benefits, is commonly called the "magic juice". It has been found that adding carrot juice to peoples diets greatly improves their health. And its delicious taste makes it popular with all members of the family as a beverage.

Carrot juice is one of the richest sources of vitamin A that can be used in the daily diet. Lack of vitamin A can cause dryness and damage to the skin, nails and hair. Drinking carrot juice to increase the vitamin A in the diet is said to be good for many parts of the body, including the bones and teeth.

Drinking carrot juice is thought to be extremely helpful to the liver (肝脏), because vitamin A helps to clean the liver and reduce fat in it. And it is suggested that drinking carrot juice should be done regularly, rather than just from time to time.

Drinking carrot juice is also thought to improve the eyesight because of the vitamin A in the juice. Lack of vitamin A can lead to night blindness, which can be very dangerous, especially when the person is driving a car. An easy way to find out if you are lacking in vitamin A is to walk from a bright room into a dark room. Your eyes may have some trouble in getting used to the change of light if you are lacking in vitamin A.

How can you make carrot juice? Wash some carrots well in cold water. Scrape (刮) them lightly, but do not peel them, as this will take away valuable vitamins and minerals that lie close to the skin.

【题目】Dolphins call out the specific names of loved ones when they become separated, a study finds.Other than humans, they are the only animals known to do this, according to the study.The big difference with dolphins is that these communications consist of whistles(鸣叫), not words.

Earlier research found that dolphins have a “signature whistle” that would be somewhat like human shouting, “Hey everybody! I’m an adult healthy male named George, and I mean you no harm.”

The new finding is that dolphins also say the names of certain other dolphins.“Animals produced copies of the same sound when they were separated from a close partner.This supports our belief that dolphins copy another animal’s signature whistle when they want to reunite with that animal,” Stephanie King, who led the study, says.

King and her colleagues collected acoustic(声音的)data from wild dolphins around Sarasota Bay, Florida, from 1984 to 2009.The researchers also studied four adult male dolphins housed at the Seas Aquarium, also in Florida.

Those males are adults that keepers named Calvin, Khyber, Malabar and Ranier, all of whom, as well as all of the wild ones, developed their own signature whistles that served as names in communication with other dolphins.

“A dolphin uses its signature whistle to broadcast its identity and announce its presence.The signature whistles allow animals to identify one another over long distances and allow animals to recognize one another and to join up with each other,” King explains.“Dolphin whistles can be heard up to 20km away, depending on water depth and whistle frequency(频率).”

The researchers said dolphins copy the signature whistles of loved ones, such as a mother, when the two are separated.These “names” are always used in positive situations, and are only directed toward loved ones.

While researchers are often unwilling to apply the word language to non-human communications, dolphins clearly have a very complex communication system.

【1】The underlined word “housed” in Paragraph 4 probably means “_________”.

A.raised B.saved C.discovered D.hunted

2】Which one plays a part in whether dolphin whistles can be heard over a distance?

A.The dolphin’s identity.

B.The water temperature

C.The whistle frequency.

D.The dolphin’s age.

3】When do dolphins copy the signature whistles of loved ones?

A.When there is a fight.

B.When their keeper comes.

C.When they are apart.

D.When they are hungry.

4The passage probably is taken from______

A.A magazine about scientific advances.

B.A website about various animals.

C.A report on animal acoustics.

D.An essay about the relationship between humans and animals.

【题目】GUATEMALA CITY(Reuters)-----A fish that lives in mangrove swamps(红树沼泽)across the Americas can live out of water for months at a time, similar to how animals adapted to land millions of years ago, a new study shows.

The Magrove Rivulus, a type of small killifish, lives in small pools of water in a certain type of empty nut or even old beer cans in the mangrove swamps of Belize, the United States and Brazil. When their living place dries up, they live on the land in logs(圆木), said Scott Taylor, a researcher at the Brevard Endangered Lands Program in Florida.

The fish, whose scientific name is Rivulus marmoratus, can grow as large as three inches. They group together in logs and breathe air through their skin until they can find water again.

The new scientific discovery came after a trip to Belize.

“We kicked over a log and the fish just came crowding out,” Taylor told Reuters in neighboring Guatgemala by telephone. He said he will make his study on the fish known to the public in an American magazine early next year.

In lab tests, Taylor said he found the fish can live up to 66 days out of water without eating.

Some other fish can live out of water for a short period of time. The walking catfish found in Southeast Asia can stay on land for hours at a time, while lungfish found in Australia, Africa and South America can live out of water, but only in an inactive state. But no other known fish can beout of water as long as the Mangrove Rivulus and remain active, according to Patricia Wright, a biologist at Canada’s University of Guelph.

Further studies of the fish may tell how animals changed over time.

“These animals live in conditions similar to those that existed millions of years ago, when animals began making the transition (过渡) from water onto land,” Wright said.

【1】The Mangrove Rivulus is a type of fish that __________.

A. likes eating nuts

B. prefers living in dry places

C. is the longest living fish on earth

D. can stay alive for two months out of water

【2】Who will write up a report on Mangrove Rivulus?

A. Patricia Wright B. Scott Taylor

C. Scientists from Belize D. Researchers in Guatemala

【3】According to the text, lungfish can____________.

A. breathe through its skin

B. move freely on dry land

C. remain alive out of water

D. be as active on land as in water

【4】What can we say about the discovery of Mangrove Rivulus?

A. It was made quite by accident

B. It was based on a lab test of sea life

C. It was supported by an American magazine

D. It was helped by Patricia Wright
