【推荐1】A safari park is a park in which wild animals are kept. They are mainly located in east or central Africa. They often occupy a very wild area, with mountains and rivers. To visit the park and look at the animals, people have to drive around in a car for a few of hours because the park is huge.
In south Africa there is a safari park, which contains all sorts of wild animals like lions, elephants, rhinoceroses, zebras, wild pigs, deer and giraffes.
There is a wild road leading through the park, but nobody is permitted to walk on the road. Anyone traveling in the park has to go in a car because wild animals may fiercely attack people. From the car he may see almost every types of African wildlife. Some of these are getting rare because people kill them for various reasons. For example, rhinoceroses are killed for their horns, which are used in traditional Chinese medicines for colds and headaches. Perhaps they will be seen only in museums and books one day.
Travels may purchase food for the animals. They can feed them when they tour the park. Of course, they should not feed them in a close distance because the wild animals may attack people. In addition, they should only give proper food to the animals.
A traveler may carry a gun with him in his journey. The gun is given to him by the government. However, it is not used for hunting. In fact, a seal(封条) is fixed to it. The traveler may fire at a wild beast to defend himself in case he is attacked. However, he has to prove to the government that he has been attacked and that he has not fired at a harmless animal.
1. When travelers feed the animals, they should _________.

A．give nutritious food	B．stay away from the animals
C．stand close	D．use tools

2. The government knows whether the gun is fired by the traveler or not by ___________.

A．checking the seal	B．hunting the animals
C．following the traveler	D．observing the traveler

3. What is the best title of this passage?

A．Protecting Wild Animals

B．Traveling in South Africa

C．A Safari Park in South Africa

D．Wild Animals in South Africa

【推荐2】Scientists have already studied how dogs respond to people’s behavior and speech. But researchers are just scratching the surface of human-cat interactions. House cats do appear to respond to the expressions on people’s faces. Cats can also tell different human voices. But can cats recognize their own names?

Saito, a psychologist at Sophia University in Tokyo, and her colleagues decided to find the answer. They asked the owners of 77 cats to say four nouns of similar length followed by the cat’s name. Cats gradually lost interest in each random(随机的) noun. But when the owner said a cat’s name, the cats reacted strongly. They moved their ears, head or tail, changed their back paw’s position. And, of course, they miaowed.

These findings mean that cats join the ranks of animals that have shown some sort of response in experiments to the names people give them. Those animals include dogs, dolphins, apes and parrots. It’s hard to compare the number of words across species, though. Some dogs, for example, can tell the difference between hundreds of human words.

The study makes a strong case that cats are perfectly capable of recognizing their own names. Getting a treat or hug as a reward is part of how cats learn to recognize a name. However, owners may also use their cat’s name in a negative setting, like yelling at Fluffy to get off the stove. As a result, cats can probably learn to associate these familiar utterances with good and bad experiences, Saito notes. And that might not be great for human-cat relations. So only using a cat’s name in a positive context and using a different term in a negative context could help cats and humans communicate more clearly.

So cats may recognize their names. But will they come when called? Don’t get your hopes up.

1. What made cats react strongly according to Saito’s study?

A．Their owners.	B．A random noun.
C．Their own names.	D．A delicious meal.

2. The findings show _________.

A．all dogs will respond on hearing their names

B．it’s extremely difficult to tell cats’ names from dogs’

C．scientists know how to tell the difference between animals

D．there is difference in the number of words recognized among animals

3. Which of the following could replace the underlined word “utterances” in Paragraph 4?

A．words

B．situations

C．observations

D．owners

4. What should people avoid to improve human-cat communication?

A．Giving a treat or hug as a reward.

B．Calling their name in a positive context.

C．Using a different term in a negative setting.

D．Associating their name with bad experiences.

【推荐3】Of all the mountain gorillas that veterinarian Mike has treated in the past 18 years, a gorilla named Ijabo stands out the most. When Ijabo was three days old, an examination showed that one of his legs was badly damaged. Mike removed Ijabo’s leg below the knee. Five years later, Mike says Ijabo is doing well. “I still see him every now and again,” Mike told TFK. “It’s heartwarming.”

Mike is a co-director of Gorilla Doctors. The organization provides medical care to ill and injured mountain and Grauer’s gorillas. Its 16 veterinarians work in national parks in the Democratic Republic of the Congo, Rwanda, and Uganda. For years, the apes have fallen victim to habitat loss, poaching, and disease. According to their website, Gorilla Doctor’s task is to save the apes “one gorilla at a time”.

The doctors treat mostly gorillas that are accustomed to humans. Trackers, guides, and veterinarians check on habituated gorillas in the field several times each week. Sometimes, a gorilla has a medical problem that requires treatment.

That calls for an intervention. A helper shoots the animal with a dart(飞镖). If the gorilla appears to have a serious but treatable illness, the dart contains antibiotics to fight off infection. If it appears to need surgery, the dart contains a drug that leaves the gorilla unconscious and unable to feel pain.

Although the gorillas are critically endangered, there are signs of hope, thanks in part to Gorilla Doctors. The mountain gorilla is the only great-ape species whose population is growing.

“Habituated mountain gorillas are increasing by 4% each year, which is as fast as the human population is growing globally,” Mike says. He notes a recent study that credits the work of Gorilla Doctors for 50% of that growth. He is proud of the role his team has played in making it happen.

1. Why is Ijabo mentioned in the text?

A．To show Gorilla Doctors’ work.

B．To display gorilla’s living conditions.

C．To describe dangers that gorillas face.

D．To predict the difficulty gorillas may have.

2. What does Gorilla Doctors do for mountain and Grauer’s gorillas?

A．Offer training.

B．Help them produce babies.

C．Form a good environment.

D．Provide medical care.

3. What’s Paragraph 4 mainly about.?

A．How to save a sick gorilla?	B．How to find a sick gorilla?
C．How to feed a sick gorilla?	D．How to find food for sick gorillas?

4. Why does Mike feel proud?

A．His team has been famous.

B．His team has played a great role in increasing gorillas population.

C．His team has earned a lot of money for studying mountain gorillas.

D．More and more doctors join in his team to help mountain gorillas.

【推荐2】More than 5, 000 species of birds manage annual round-trip migrations（迁徙）. These journeys can be thousands of miles, with many birds often returning to the exact same nesting and wintering place from year to year.

Migration is very important in the life cycle of birds, and without this annual journey many birds would not be able to raise their young. Birds migrate to find the richest and most abundant food that will provide adequate energy to raise young birds. If no birds migrated, competition for adequate food during breeding（繁殖）seasons would be fierce and many birds would starve.

Of course, not all birds migrate. Some birds can take advantage of different food sources（来源）as seasons change, allowing them to stay in one place all year round. Other birds are better adapted to cold climates with thicker fat reserves and better feathers, and they can survive long cold seasons while they forage for winter food. For more than half the world's birds, however, migration is necessary to stay alive.

When the timing is right for their migrating needs, birds will begin their journey. Food, weather, temperature and illness or injury are several minor aspects that may affect migration by a day or two, but most bird species follow precise migration "schedule". While migration is at its finest during spring and fall, birds migrate all throughout the year. Migration is actually an ongoing process and there are always birds at some stage of their journeys. The distance the birds must fly, the length of time it takes to mate and the amount of young birds all affect when any one species is migrating.

Migratory birds have several changes before the journey. Among them is hyperphagia, the process of migration-related weight gain. As daylight changes and migration times near, a bird's hormone levels will change and they will build a greater fat supply. Besides, old, ragged feathers create more wind drag and air resistance, which requires a bird to use more energy in flight, so many birds replace old feathers with new ones.

1. Without migration, many birds would          .

A．stop reproducing during breeding seasons

B．abandon young birds for lack of food

C．be unable to find places for nesting

D．be in danger of starvation

2. What does the underlined phrase "forage for" mean in Paragraph 3?

A．Run out of.	B．Cut down on.
C．Search for.	D．Wait for.

3. What can we learn about birds' migration?

A．Most birds begin their journey at the arrival of spring.

B．Warm temperature usually advances it by a day or two.

C．There is almost little migration of birds in winter.

D．Birds' migration is affected by various aspects.

4. How will migratory birds benefit from the process of hyperphagia?

A．They will tend to use less energy in flight.

B．They will store enough energy for travelling.

C．They will replace old feathers with new ones.

D．They will better sense the changes of daylight.

【推荐3】When they look at the sky, people usually find the sky looks blue—not orange, red, green or yellow. Do you know why?

Unlike the moon, the earth is surrounded by an atmosphere. That atmosphere is a mixture of gases, mostly nitrogen and oxygen. The way the sunlight travels through the atmosphere makes the sky colored.

Why blue? It doesn’t look like it, but light is made up of several different colors, like you see in the rainbow. Each of these colors travels in a wave, but the wavelength(distance between the tops of each wave) varies. Red light has a long wavelength, while blue light has a much shorter wavelength. When light from the sun enters our atmosphere, the wave collide(碰撞) with gas molecules(分子)。 The longer wavelengths, like red and yellow, pass straight through and appear to us as “regular” sunlight. Shorter wavelengths, like blue, bump into the gas molecules and scatter(分散) in different directions. Some of it still makes it through directly, but the rest is reflected back to our eyes from all directions, so the whole sky looks blue.

The sky usually looks light blue. But it would be dark blue if you stood on top of the highest mountain, where there is less air to scatter the sunlight.

Sometimes the sky doesn’t look blue. At sunrise and sunset, the light from the sun sometimes scattered in some way that you see red, orange, and other colors in the sky.

1. Why does the sky look blue?

A．the blue light is scattered most among all the lights.

B．the sunlight is made up of all the colors the same as a rainbow.

C．the sunlight is blue itself.

D．the sunlight contains only blue light.

2. According to the passage the sky astronaut(宇航员)sees would be ______.

A．dark blue	B．deep green
C．light blue	D．red or orange

3. When can you see the sky become red or orange?

A．when you stand on the top of the mountain	B．in the sunshine
C．in the morning	D．when you are in space

4. Which of the following is NOT true?

A．The sky looks orange at dusk.

B．We usually just see the blue light when the sunlight passes through the air.

C．When you stand on the peak of the highest mountain the sky looks light blue.

D．The red light is scattered less than the blue light.
