Monkeys surprise us

Humans are the most intelligent animals on Earth. 1.But sometimes, our way of thinking can become an obstacle (障碍).

Julia Watzek, a graduate student in psychology at Georgia State University, US, recently did some research on the problem-solving abilities of both monkeys and humans.2.They intended to test their ability to change their strategies(策略) in the game. In this game, each player was shown four squares on a computer screen: one striped square, one spotted square and two blank squares. While being trained to play the game, they learned that clicking the stripedsquare and then the spotted square would cause a blue triangle to pop up in one of the blank squares. Clicking on the blue triangle would give them a reward. 3. But partway through the game, the researchers introduced a shortcut (捷径). Suddenly, the blue triangle started appearing at the start of gameplay, alongside the striped and spotted squares.4.Remarkably, about 70 percent of the monkeys figured out this shortcut immediately. 5. Only 1 out of 56 human players figured out the shortcut right away.

Watzek’s conclusion was that humans tend to get “stuck in their ways” when it comes to strategic thinking. Things such as standardized testing and formal schooling might cause humans to use the same strategy over and over, even when it doesn’t work very well.

A.Monkeys never did better than human.

B.She and her team had them play a simple game.

C.The spotted square didn’t appear at all till the end.

D.Humans, on the other hand, were slow to figure it out.

E.We have mental abilities that other animals don’t have.

F.If a player clicked on the blue triangle, they’d receive their reward right away.

G.Human players would hear a “woop!” sound and monkey players would receive a snack.

Tigers are among the most admired and most feared animals in the world . When we think of a tiger, we think of danger. We think of the big teeth and large feet of it. We also think of beauty.

The tiger is a hunter that hunts alone. In fact , tigers are probably better than any other land mammal(哺乳动物) at catching large animals without help. Even so, the life of this big-game hunter isn’t easy. Finding food can be difficult, especially for a tiger that is old or weak. Most of the animals it tries to attack get away. A tiger sometimes goes weeks without eating. When that happens, it may hunt animals that can be dangerous even for a tiger.

When they are in a bad situation, some tigers may even attack humans. But in fact, tigers kill very few people each year. Most tigers run away when they see people.

What tigers have done to people can’t compare to what people have done to tigers. Over the last 200 years, we have almost killed tigers in the wild(野外). Today, the tiger is one of the most endangered animals on Earth.

A tiger may live 20 years or more, if it is not disturbed by humans. Female(雌性的) tigers usually live longer than male(雄性的)tigers, because the males live more dangerously.

It isn’t easy for people to tell a male from a female unless the female happens to be with her babies.Only females take care of the young. The big difference between males and females is size. Male tigers are much bigger.

Tigers are big eaters. In a single year, one tiger must eat about 70 deer or other large animals. That is one reason why tigers hunt alone. If they lived in big groups, they could never find enough animals to feed them all.

1.What’s the topic sentence of Paragraph 2?

A. The tiger is a hunter that hunts alone.

B. A tiger sometimes goes weeks without eating.

C. The life of this big-game hunter isn’t easy.

Sharks are among the oldest animals on Earth. There are hundreds of kinds of sharks. Most are about two meters long. The dogfish shark, however, is less than twenty centimeters in length. A shark has an extremely good sense of smell. It can find small amounts of matters in water, such as blood, body liquids and chemicals produced by animals. These powerful senses help sharks find their food. Sharks eat fish, other sharks, and plants that live in the ocean.

Sharks grow slowly. About forty percent of all sharks lay eggs. The others give birth to live young. Some sharks carry their young inside their bodies as humans do. Some sharks are not able to reproduce until they are twenty years old. Most reproduce only every two years. And they give birth to fewer than ten young sharks. For this reason, over-fishing of sharks is of special danger to the future of the animal.

Sharks are important for the world’s oceans. They eat injured and diseased fish. Their hunting activities mean that the numbers of other fish in ocean waters do not become too large. This protects the plants and other forms of life that exist in the oceans.

People hunt sharks for sport, food, medicine and their skin. Experts say the international market for some kinds of sharks has increased because many parts of a shark are valuable.Collectors pay thousands of dollars for the jaws of a shark. Shark liver oil is a popular source of Vitamin A. The skin of a shark can be used like leather.

In Asia, people enjoy a kind of soup made from shark fins. Experts say a fisherman can earn a lot of money for even one kilogram of shark fins. Sharks are among the oldest animals on Earth, but some sharks are in danger of disappearing from Earth. If too many sharks in one area are killed, that group of sharks may never return to normal population levels.

1.. Which of the following words best describes the situation sharks are in?

2. Sharks eat other fish, __________.

3. According to the passage, many parts of a shark are valuable EXCEPT ________.

4.The author thinks that______.

Stories of Animals Acting Just Like Humans

◆Monkeys do math

If monkeys manage the world, we might have stayed away from the recent banking hardship. In an experiment led by Keith Chen at Yale, monkeys showed an understanding of pricing and planning the money, as well as a wish to stay away from losses when required to buy food with money. Makes sense this one looks like it’s checking its stocks (股票) on a smart phone. Think that’s impressive?

◆Camel eats breakfast with people

The first time Joe ate with British farmers, he was uninvited. The four-year-old Bactrian camel stuck his head through their open kitchen window, and emptied a fruit bowl. Now the couple, who rent out reindeer, camels, goats, and other creatures for television shows, movies, and photo shoots, set a place at their table for the confident double-humped creature, where Joe eats grain food and his favorite: bananas on toast.

◆Marmots (土拨鼠) befriend a boy

A group of marmots in the Austrian Alps has made friends with eight-year-old Matteo Walch by chance, whose family vacations there in summer. Typically, they beat their tails, chatter, and whistle to warn other marmots of danger, but with Matteo, they behave much differently, allowing the boy to feed, pet, and even touch noses with them. “Watching them makes me feel a connection with nature,” says Matteo. How sweet!

1.In what way do monkeys behave like humans according to the text?

A. In character. B. In intelligence.

Some of the planet’s most precious animals and plants are disappearing, according to the World Conservation Union (IUCN). The group, based in Switzerland, works with governments and experts to protect threatened species. On September 12, the IUCN released its Red List, a list of species at greatest risk of extinction.

The list includes 41,415 animals and plants. The IUCN says that habitat destruction, hunting and other causes threaten one in four mammals, one in eight birds and one in three amphibians(两栖动物).

Who is to blame?

Scientists believe that 99 percent of threatened species are at risk because of human activity. “We are losing animals and plants at a high rate,” says Julia Marton-LefEevre, director general of the IUCN. “We need to change our behavior.” Warmer oceans and over-fishing are changing sea life. This year for the first time corals(珊瑚) made their appearance on the list. The gharial, a crocodile living in India and Nepal, has lost almost 60 percent of its population in the last 10 years. It is a victim（受害者）of habitat destruction.

Still, the news is not all bad. Thanks to efforts made to protect it, the Mauritius echo parakeet, a bird once endangered, has seen an increase in its population. “This shows that protection methods can work,” says Marton-LefEevre. “That’s the message we want to send to young people.”

In China the new reserve（保护区）itself is part of green efforts that have seen more than 2,400 nature reserves of various kinds being set up, covering more than 15 percent of the nation's land area, official figures showed.

"The country's natural resources(资源) have benefited from conservation," said Lei Guangchun, director of the nature reserve department of Beijing Forestry University. "It is a big increase nowadays compared with other countries." Lei said.

The total areas of China’s natural reserves have covered 1.38 million km2, which accounts for 15.4% of China’s area, higher than both the world average（平均水平） of 11% and the rate in most developed countries.

Li Zhong, an official in charge of the nature reserves office with the State Forestry Administration, thought it was important to increase investment（投资） in such reserves at all levels.

1.What do we know about the IUCN?

A. A union for listing animals and plants on the earth

B. A group of volunteers who are interested in wildlife

C. An organization concerning the protection of rare species' survival

D. A government made up officials, scientists and experts

2. What can be concluded from the passage?

A. All the protection methods can’t work.

B. The IUCN does most of the protection.

C. The efforts China makes has paid off.

D. Enough is done in wildlife protection.

3.Which of the following is not the cause of the disappearance of the animals?

A. Bad weather     B. Over-hunting    C. Warmer oceans    D. Habitat destruction

4.Which of the sentence is NOT true?

A. China has been paying great attention to protecting the natural resources.

B. China has set up a lot of natural reserves.

C. The natural reserves in China cover more than 15 percent of the nation's land area.

________ surprises most of us.

高一英语单项填空中等难度题查看答案及解析

Birds’ feathers are some of the most strikingly variable animal characteristics that can be observed by the eyes. The patterns that we see in birds’ feathers are made up of combinations of scales, bars, and spots.

We already know why birds have colored feathers. Generally, the color of feathers may protect a bird from being noticed by the enemy in the environment, or it can make a bird more appealing to potential mates by helping them to stand out. These aspects are well known. A greater mystery has been how the patterns are created.

Dr. Ismael Galván and his team studied the color of feathers to see what types of colors were present in birds’ complex feather patterns. The study shows they mainly consist of two types of colors: melanin（黑色素）, which produce a range of black, grey, brown, and orange color, and carotenoids（类胡萝卜色素）, which are used to create brighter colors.

Birds cannot produce carotenoids on their own. For feathers with bright colors, birds must consume food items that contain these paints, and the carotenoids circulate through the blood and to the feather. Melanin, on the other hand, is produced by special cells in the birds’ bodies.

The team found that about 32% if the species studied have complex color patterns, with the vast majority of these complex patterns produced by melanin rather than carotenoids. If the birds were artists, they would use carotenoids as a broad brush to produce color patches, with melanin as a detail paint brush to produce more complex designs.

But a few birds are exceptions to this rule: Three bird families do have complex patterns without melanin.

1.What does the underlined word “it” in paragraph 2 refer to?

A. The environment.　　 B. The color.

C. The feather.　　 D. The enemy.

2.What will happen if birds can’t get enough carotenoids?

A. They’ll gradually die out.　　 B. Their color will be less bright.

C. They will get caught eventually.　　 D. They’ll be discovered more easily.

3.What rule can we get from paragraph 5?

A. All birds have complex color patterns.

B. Birds are expert in painting colors.

C. Melanin plays a greater part in bird colors.

D. Carotenoids can bring 32% of the color patterns.

4.Which can be the best title for the text?

A. How Do Birds Get Their Colors　　 B. Which Color Is Common to Birds

C. How Do Birds Tell Different Colors　　 D. Why Birds Have Colored Feathers
