Dogs are often called “man’s best friend” and make ideal pets.     1     most attractive quality of a dog is its faith in its owner. They always greet us when we come home and they will never leave us when we are     2     danger. For example, there was a very sick man and his dog barked and barked until the rescue team     3     (arrive).

Furthermore, dogs are strong animals     4     will protect us. Houses with dogs are considered much     5     (safe) than those with burglar alarms (防盗警报器). Not only will they stop thieves,     6     they will also guard against fire. For example, there was a serious fire and a dog managed     7     (pull) its owner out.

And     8     (final), dogs can be trained by people. Dogs can do a number of things that people can not. For example, they can find drugs, bodies, illegal DVDs and hunt down prisoners with     9     (they) nose. They’re also used to help the elderly and disabled.

To sum up, dogs are really friendly, civilized (文明的) and loyal     10     (partner) .

2 . How can a creature weighing over 5 tons and normally taking 150 kilograms of food and 120 liters of water per day survive in a desert environment?

In the southwest African country of Namibia, and the Sahara lands of Mali further north, the desert elephant does just that.

Although not regarded as a separate species from the African elephant, the desert cousin differs in many ways. Their bodies are smaller, to absorb less heat, and their feet are larger for easier walking across sandy surfaces. They are taller, to reach higher branches. They have shorter tusks (象牙), and most importantly, longer trunks to dig for water in riverbeds.

Desert elephants can travel over 70 kilometers in search for feeding grounds and waterholes, and have a larger group of families, They drink only every 3-4 days, and can store water in a “bag” at the back of their throat, which is only used when badly needed. Desert elephants are careful feeders — they seldom root up trees and break fewer branches, and thus keep what little food sources are available. Yong elephants may even eat the dung (粪便)of the female leader of a group when facing food shortage.

During drought (干旱) they are unlikely to give birth to their young but with good rains the birthrate will increase greatly. Desert elephants have sand baths, sometimes adding their own urine (尿液) to make them muddy!

As we continue to overheat our weak planet, it can only be hoped that other animal species will adapt (适应) as extraordinarily well to change as the desert elephant.

3 . Population data for European mountain birds have been for the first time combined in a recent study, with worrying results: the abundances of mountain-specialist birds has declined by as much as 10% in the 2000s.

Ecological communities in mountain areas include species not found in any other habitats. These species are also very susceptible to climate change, as global warming is reducing their liveable habitats. In principle, species may relocate further up the mountains, but closer to the top their habitat inevitably shrinks.

According to the new article, the abundance of European mountain birds has in fact declined in line with climate change projections.

The recently released study examined the population trends of 44 bird species in the 2000s in the mountain and fell regions of Fennoscandia, Great Britain, the Alps and the Iberian Peninsula. A decline was seen in 14 of the observed species, while eight of them saw significant increase.

“On average, population decline among the species studied was 7% over the 13-year research period, making the situation of mountain birds distinctly worse compared to, for example, European forest birds, whose numbers did not change during the same period,” explains Aleksi Lehikoinen, an Academy of Finland research fellow at the Finnish Museum of Natural History Luomus (part of the University of Helsinki), who headed the study.

The situation is the direst for species that only inhabit mountain regions and are unable to live in other European environments. For these species, known as mountain specialists, the numbers dwindled by as much as 10% during the monitoring period.

A．All 44 bird species decreased.

B．Only 8 of the species declined.

C．14 of the observed species declined.

D．There was no change in the number of the bird species.

4. What does the word “direst” mean in the last paragraph?

4 . As many as 10 of the 17 kinds of penguins may be in danger of disappearing. The number of penguins has decreased by 30% since 1987.

Penguins are black and white birds that live in the southern part of the world. They are common in South America, New Zealand, Australia and South Africa. Many live near cold waters. But some live near warm waters in Galapagos Islands. Penguins cannot fly, but they are fine swimmers. Penguins eat fish and krill(磷虾). The warming of the earth is the reason for the decrease in the number of penguins. The heating of the air has caused ocean waters to become warmer. Higher water temperatures have reduced the supply of fish and krill. Some years later these birds are completely unable to reproduce(繁殖). Besides, many adult penguins die of hunger.

Widespread(广泛的)fishing, exploration for oil and oil leaks(漏)also make penguins in danger. Poisonous things in ocean waters are another danger. Penguins also have their enemies, including wild dogs, sharks, seals and sea lions.

News about penguins is not all bad, however. Several years ago, oil leaking from a ship hurt 40% of the penguins in South Africa. The penguins became covered with oil. But thousands of people helped clean and treat the birds well. Then they returned the penguins to the wild. Now these South African penguins are reproducing in higher numbers than before the oil leaking.

1. The first paragraph tells us that________.

A．some new kinds of penguins appear

B．all the penguins are in danger of disappearing

B．Widespread fishing.

C．Human's killing.

D．Warming of the oceans.

3. Whar's the best title of the passage?

A．Protecting our environment

B．Ocean waters are polluted

C．The decrease in the number of penguins

D．Ocean is important for penguins

6 . Pets are popular. They’re good listeners, they encourage us to exercise, and they’re always on our side when we argue with others. They can bring people comfort and pleasure.

But it is important to keep in mind that pets can carry diseases that can make you sick. Washing your hands often — especially after you touch, feed, or clean up a pet — is the best way to keep yourself healthy and prevent the spread of disease. Be sure to clean your fingernails (指甲) carefully every time you wash.

You also can protect your health by wearing gloves while cleaning animal cages or cat litter boxes. Avoid washing your pet in the bathtub (浴缸), but if you do, always disinfect (消毒) the tub immediately afterward.

Be sure to bring your pet to the hospital for examinations every two weeks or month and whenever your pet is sick or injured.

You can do a few other things to keep yourself and your pet healthy. Only give your pet food that has been planned ahead for them. It’s not a good idea to share your food with your pet. Human food (like chocolate) can make animals sick. Never feed your pet raw (生的) meat because it can carry germs (细菌) that cause serious illness.

And funny as it can be to see your dog or cat drinking from the toilet, don’t let pets do this. It’s bad for your pet’s health! Give them clean, fresh water to drink at all times.

Never give milk to cats. The only milk an animal should drink is from its mother. Cow’s milk is not for pets, especially for cats, as it makes them sick.

Finally, some animals aren’t pets. Don’t take in a wild or abandoned (被抛弃的) animal as a pet because it may have diseases that could make you or your family sick. Instead, turn to an animal rescue group that is trained in helping sick or abandoned animals.

The spider monkey has long, thin arms with hook-like hands that allow it to swing (摇摆) through the trees. It has a prehensible (缠绕性的) tail, which means it can grasp and can be used like a     1    (five) leg to grab trees. During the day, the spider monkey searches     2     fruits, which make up the main part of its diet. They will also eat flowers, seeds, leaves, and small insects during the dry season     3     fruits aren’t available. They spend most of the daylight hours climbing and swinging through the high branches of trees.

The brown-headed spider monkey lives in a large community of about 20 to 100 male and female monkeys. Females     4    (normal) give birth to only a single baby each year or two. Young monkeys are carried on their mothers’     5    (stomach) until about 16 weeks old. Then they are strong enough     6    (ride) on their mothers’ backs.
