Elephants are the largest land animals and they need plenty of living span. They have seasonal migration(迁徙) routes. As human populations rise, elephant land is being cleared for agriculture and other kinds of development.
When animals are effectively trapped on small areas of land, it restricts the gene pool and also results in a shortage of food. Where elephant reserves (保护区 ) border agricultural areas, elephants are often attracted to leave parks to attack crops and barns. Only the strongest walls will stop an adult elephant, so farmers have great difficulty protecting their fields.
In India, elephants don’t only attack for food. Some even have developed a taste for rice beer. In Assam, elephant-human conflict has resulted in the death of more than 150 people and 200 elephants in two years.
Poverty leads to the killing of elephants for meat. If people don’t have enough food and their governments cannot afford to enforce poaching(偷猎) bans, it’s not difficult to predict the outcome.
Ivory comes from elephant tusks, which can grow to be 3 metres long. Both male and female African elephants have large tusks.
Most new ivory comes from Africa and is sold as a high status material in Asian countries such as Thailand, mainland China and Japan. It can fetch $150 a pound and is carved to make decorations, chopsticks and ink stamps(印章). The conservation priority(重点) here is to change public attitudes.
In some countries in southern Africa, where conservation efforts have been successful, there is not enough room for a growing elephant population and animals have to be killed. A CITES meeting in November 2002 ruled that Botswana, Namibia and South Africa may sell stock-piled(库存的) ivory, starting in 2004.
Many conservationists are convinced that this will fuel the demand for ivory and lead to more illegal poaching, they say it is almost impossible to tell legal from poached ivory. The governments argue that the sales will be used to fund conservation work.
64. Which of the following isn’t the result of smaller elephant land?
A. Seasonal migration. B. Elephant-human conflict.
C. Restricting the gene pool. D. Shortage of food.
65. The most important thing to protect elephants is _______.
A. to build strongest walls
B. to sell stock-piled ivory instead of illegal ivory
C. to enforce poaching bans
D. to change people’s ideas
66. What does the underlined word “this” in the last paragraph refer to?
A. The killing of dephants for meat.
B. The ban of the trade in African elephant ivory.
C. The selling of stock-piled ivory.
D. The sales to fund conservation work.
67. According to the passage, we can infer that_______.
A. farmers have trouble protecting their field since no walls can stop an adult elephant.
B. if the government could help solve poverty, there would be less killing of elephants.
C. only male elephants in Africa have tusks as long as 3 meters.
D. since there is not enough room for a growing elephant population, there is no need to ban poaching all over Africa.

Orcas, or killer whales, are the largest of the dolphins and one of the world’s most powerful animals feeding on meat. They feast on marine mammals such as seals, sea lions, and even whales, employing teeth that can be four inches (ten centimeters) long. They are known to grab seals right off the ice. They also eat fish, squid (鱿鱼), and seabirds.
Though they often frequent cold, coastal waters, orcas can be found from the polar regions to the Equator (赤道).
Killer whales hunt in deadly groups, family groups of up to 40 individuals. There appear to be both permanent and temporary group populations of killer whales. These different groups may hunt different animals and use different techniques to catch them. Permanent groups tend to prefer fish, while temporary groups target marine mammals. All groups use effective, cooperative hunting techniques that some are similar to the behavior of wolf packs.
Whales make a wide variety of communicative sounds, and each group has various noises that its members will recognize even at a distance. They use echolocation (回波定位) to communicate and hunt, making sounds that travel underwater until they meet objects, then reflect back, showing their location, size, and shape.
Killer whales are protective of their young, and other adolescent females often assist the mother in caring for them. Mothers give birth every three to ten years, after a 17-month pregnancy.
Killer whales are immediately recognizable by their special black-and-white coloring and are the intelligent, trainable stars of many aquarium shows. Killer whales have never been widely hunted by humans.
1. Killer Whales do not feed on ______.
A. seabirds B. seals C. fishes D. seaweeds
2.【The following aspects about killers whales are mentioned except ______.
A. hunting B. communication C. weight D. habitats
3.We can conclude that ______.
A. people can find killer whales everywhere around the world
B. killer whales live in different groups and never live alone
C. by making sounds killer whales hunt and communicate
D. humans’ hunt has made killer whales being endangered
4.Killer Whale are often seen in some aquarium shows because ______.
A. they are able to be trained
B. they have special body colors
C. they must be protected
D. they have never been hunted

The African elephant, the largest land animal remaining on the earth, is of great importance to African ecosystem(生态系统). Unlike other animals, the African elephant is to a great extent the builder of its environment. As a big plant-eater, it largely shapes the forest-and-savanna(大草原) surroundings in which it lives, therefore setting the terms of existence for millions of other animals that live in its habitat.
It is the elephant’s great desire for food that makes it a disturber of the environment and an important builder of its habitat. In its continuous search for the 300 pounds of plants it must have every day, it kills small trees and underbushes, and pulls branches off big trees. This results in numerous open spaces in both deep tropical forests and in the woodlands that cover part of the African savannas(热带草原). In these open spaces are numerous plants in various stages of growth that attract a variety of other plant-eaters.
Take the rain forests for example. In their natural state, the spreading branches overhead shut out sunlight and prevent the growth of plants on the forest floor. By pulling down trees and eating plants, elephants make open spaces, allowing new plants to grow on the forest floor. In such situations, the forests become suitable for large hoofed plant-eaters to move around and for small plant-eaters to get their food as well.
What worries scientists now is that the African elephant has become an endangered species. If the elephant disappears, scientists say, many other animals will also disappear from vast areas of forest and savanna, greatly changing and worsening the whole ecosystem.

A.Disappearance of African elephants. |
B.Forests and savannas as habitats for African elephants. |

2.What does the underlined phrase “setting the terms” most probably mean?

A.The African elephant is the largest animal on the earth. |
B.African elephants have 300 pounds of plants every day, including small trees and underbushes. |
C.The African elephant is in a way the builder of the environment like other land animals. |

The largest land animal remaining on the earth, the African elephant is of much importance to African ecosystem. Unlike other animals, the African elephant is to a great extent the builder of its environment.
