Question

【题目】For 40 years, people in London have been happy to see parakeets (马尾鹦鹉) in their parks. The shocking green body and long tail have brought a bright color to the parks, which have attracted a lot of people.

However, the parakeets are no longer welcome. They will push out local birds from trees to build their own nests, and will also take most of the food in the parks, such as seeds, fruit and nuts.

Sometimes by accident, plants and animals are carried to new places. They are transported by trains, ships or even planes. Often, animals like fishes get transported in the water containers of ships. When these ships reach new places and pump out the water from their tanks, these animals will start a new life in a new place.

Sometimes people take plants and animals from one part of the world to the other to solve a problem. But it will create a bigger problem. Years ago, the sugarcane (甘蔗) farmers of northern Australia brought the toads (蟾蜍) from South America to their farms. They thought they would kill the beetles (甲虫) that harm the sugarcane crops. But the toad has done much more. It is now killing Australia’s native animals, such as snakes, water birds and so on.

【1】People get interested in parakeets mainly because of ____.

A. their appearance B. their singing

C. their behavior D. their living environment

【2】How do the parakeets affect the local birds?

A. They sometimes kill the local birds.

B. They destroy trees which the local birds live in.

C. They take the local birds’ nests and food.

D. They have attracted much of people’s attention.

【3】What is the third paragraph mainly talking about?

A. How animals and plants come to new lands.

B. How a new animal affects the local animals.

C. Why some plants are introduced to a new place.

D. The role of ships in transporting animals and plants.

【4】What can we learn about the toads?

试题分析：本文属于说明文，本文通过介绍伦敦公园里的马尾鹦鹉影响当地生态的事情引出了动植物迁移到新的地方对当地的生态会产生一定的影响。

【1】A 细节理解题。根据第一段最后一句The shocking green body and long tail have brought a bright color to the parks, which have attracted a lot of people.可知这种鹦鹉绿色的身体和长长的尾巴给当地的公园添加了新的色彩，也就是说是这种动物的外表让给他们更受欢迎。故A正确。

【2】C 细节理解题。根据第二段第二句They will push out local birds from trees to build their own nests, and will also take most of the food in the parks, such as seeds, fruit and nuts.可知马尾鹦鹉会赶走其他的鸟儿并把大部分的食物都夺走。主要是从这两方面影响当地的鸟儿。故C项正确。

【3】A 段落大意题。根据本段第一句Sometimes by accident, plants and animals are carried to new places.植物和动物在不经意的时候被带到新的地方，接下来列举了多个事例来说明很多动植物都这样来到新的地方的。所以本段主要讲述的是动植物是如何来到新的地方的。故A正确。

【4】D 推理判断题。根据文章最后一句But the toad has done much more. It is now killing Australia’s native animals, such as snakes, water birds and so on.可知人们原来希望这种蟾蜍能够消灭甲虫，但后来这种甲虫还杀死很多其他的动物，如蛇、水鸟等，给当地带来了更为严重的问题。故D正确。
