Scientists did a research about more than 4, 000 species(物种) from around the world. They found that about half of them are on the move. To find cooler places, they are going up hills and mountains, and heading from the equator(赤道) to the poles(极地). Animals on land are moving more than 16 kilometers every 10 years, while sea animals are moving four times faster.
In North America, for example, pikas(鼠兔) used to climb 13 metres every 10 years. But since the late 1990s, they have climbed an average of 145 metres every 10 years. Also, moths(飞蛾) on the mountains in Bomeo, a large island in the Pacific Ocean, moved 67 metres up the mountain between 1965 and 2007 to get away from rising temperatures.
Moving species can cause problems. As species move to new areas, the local environment and other animals may not be able to deal with it. In Australia's seas, tropical(热带的) fish are coming in and eating the kelp(海藻) forests. This is bad news for the local rock lobster(岩石龙虾) as it also feeds on kelp forests.
Scientists also warn that the movement of species can make climate(气候) change more serious. Take bark beetles as an example. They are harmful and can cause more trees to die. As a result, these trees offer more fuel for forest fires, giving off more planet-warming carbon dioxide(二氧化碳), reported The Guardian.
“Climate change is still going on. There is a risk that many species may die out as a result of all these changes,” a professor of the University of York, UK, told The Independent.

D. It mainly influences the northern half of the world.

1.B 2.D 3.B 4.D 5.A

1. 细节理解题：原文第一段提到研究覆盖超4000个物种，约半数物种正在迁徙，目的是找到更凉爽的区域。A选项表述“约2000个物种将居住在极地”不符合原文；C选项“陆地动物10年内会迁入海洋”原文无提及；D选项“陆地动物比海洋动物移动更快”和原文“海洋动物移动速度是陆地动物的4倍”矛盾，只有B选项“物种正在向更凉爽的区域迁徙”符合研究发现。
2. 词义猜测题：划线词所在句说明物种从赤道向极地移动来寻找凉爽区域，前文已经出现"on the move"描述物种迁徙，因此"heading"此处含义是“向……移动”，对应D选项Moving toward。A选项“向上攀爬”、B选项“游入”、C选项“导致”均不符合语境。
3. 细节理解题：第二段提到鼠兔过去每10年向上攀爬13米，上世纪90年代末之后每10年平均攀爬145米，说明鼠兔向山顶迁徙的速度正在加快。A选项“鼠兔过去住在海拔13米的山上”表述错误；C选项“飞蛾搬到Bronco的岛屿居住”和原文的Borneo（婆罗洲）不符；D选项“飞蛾2007年就停止向山移动”原文无依据，因此B选项正确。
4. 推理判断题：第三段提到迁徙来的热带鱼类吃掉海藻林，而本地岩石龙虾同样以海藻林为食物，举例是为了说明外来迁入的物种会抢占本地物种的食物资源，导致本地物种食物减少，对应D选项。A、B、C的表述都不是作者举龙虾例子的目的。
5. 细节理解题：文章提到物种迁徙会破坏本地生态，还会加剧气候变化，甚至带来大量物种灭绝的风险，说明物种迁徙会让整体环境情况对人类而言变得更糟糕。B选项“它是森林火灾的主要原因”表述错误；C选项“它会减缓气候变化”和原文“加剧气候变化”矛盾；D选项“它主要影响北半球”原文无提及，因此A选项正确。
