Understanding ideas
1 Look at the pictures and choose the animals that migrate .
a monarch butterfly b Siberian crane(西伯利亚鹤,白鹤)
c Atlantic salmon d red panda(小熊猫)
e killer whale f African lion
Now talk about what you know about animal migration.
2 Read the passage and find out what mystery the scientists have
solved.
They have solved how millions of monarch butterflies manage to migrate.




The Monarch's Journey
1 Many animals move from one place to another at certain times of the year. This
annual movement is called migration. They migrate to find food,seek . .a partner,
or in search of . .warmer weather(两个动词不定式短语"to find food" "(to)
seek a partner"和一个介词短语"in search of warmer weather"并列作目的状
语。).One of the most wonderful migrations in nature is that (that是替代词,此
处替代的是the migration。that一般指代上文中出现的特指单数名词或不可数名词。)
of the North American monarch butterfly.
2 Every autumn,millions of these beautiful insects with fine black and orange wings
begin a long and difficult journey. Somehow they manage to travel around
4,000 kilometres south and find their way to California or Mexico. However,until
recently no one knew how they did this.
3 A team of scientists led by Professor . .Eli Shlizerman at the University of
Washington(动词-ed短语作后置定语,修饰A team of scientists。A team of
scientists和lead是逻辑上的动宾关系,故这里用动词-ed形式。) has now found the
answer. They have found out that the monarch is able to tell the time of day. It
uses its eyes to measure the position of the sun. These two pieces of
information—the time of day and the point where the sun is in the sky
(two pieces of information的同位语,其中where the sun is in the sky是where引导
的定语从句,修饰先行词the point,where在定语从句中作地点状语。)—allow the
butterfly to determine the way to go. Eventually ,it manages to reach the
places where it will spend the winter.
4 The solution to the mystery of the monarch's amazing ability comes at a
time when it is in serious trouble. Its population has crashed by as much as
90 per cent in the last few years"(in the last/past+一段时间"作时间状语时,句子
常用现在完成时。).Sadly, human activity is the main reason why the number of
monarch butterflies is falling(why引导的定语从句,修饰the main reason,why在从
句中作原因状语。).In many of the places where the butterfly can be found,
people are destroying the natural environment.They cut down trees and use
chemicalsthat kill the plants that monarch caterpillars . .eat.(that引导的定语从句,
修饰先行词chemicals,that在该从句中作主语,不可省略;其中又包含一个that引导的
定语从句"that monarch caterpillars eat",修饰先行词the plants, that在该从句中作宾
语。)
5 The research on the monarch's behaviour has however led to a greater
awareness of this creature .People have been working (现在完成进行时,表示动
作从过去某时开始,一直延续到现在,还可能延续下去。)together to record its
migration and make sure that there are enough plants for it to feed on .If this
works , there may come a time when the number of monarch butterflies increases
once again.The more we know about this lovely creature, the greater("the+比较级
(+主语+谓语),the+比较级(+主语+谓语)"结构,表示后者随着前者的变化而变
化。) the chance it will survive and keep its place in the natural world for a
long time to come.
黑脉金斑蝶的迁徙之旅
1 许多动物会在一年中的特定时节从一个地方迁移到另一个地方,这种一年一度的
迁移叫作迁徙。它们迁徙或为了寻找食物,或为了寻找伴侣,或为了寻找更温暖的
天气。北美黑脉金斑蝶的迁徙是大自然中最令人赞叹的迁徙之一。
2 每年秋天,数百万只这种翅膀橙黑相间的美丽昆虫都会开启一段漫长而艰难的旅
程。它们不知用什么方法,能完成约4 000千米的南行旅程,前往加利福尼亚或墨西
哥。然而,直到最近,人们才知道它们是如何做到的。
3 一支由伊莱·史莱泽曼教授带领的来自华盛顿大学的科学家团队现在已经找到了答
案。他们发现黑脉金斑蝶可以分辨出一天的时刻。它用眼睛来测量太阳的位置。这
两条信息——一天中的时刻和太阳在空中的位置——让黑脉金斑蝶确定它的路线。
最终它成功到达它过冬的地方。
4 黑脉金斑蝶这一惊人能力的奥秘被揭开时,这一生物正遭遇严重困境。近年内其
种群数量减少了90%之多。不幸的是,人类活动是黑脉金斑蝶数量下降的主要原因。
在黑脉金斑蝶生存的许多地方,人们正在破坏自然环境。他们砍伐树木,使用能杀
死黑脉金斑蝶幼虫食用的植物的化学药剂。
5 然而,对黑脉金斑蝶(迁徙)行为的研究让人们对这种生物有了更深刻的认识。
人们一直在齐心协力记录它的迁徙,并确保它有足够的植物可食用。如果这些起作
用,那么可能某个时候黑脉金斑蝶的数量会再次增加。我们对这种可爱的生物了解
得越多,它生存的机会以及长久保持它在自然界中的地位的可能性就越大。

教材语境P68 People have been working together to record its migration and
make sure that there are enough plants for it to feed on.人们一直在齐心协力记

句式剖析 本句的结构分析如下:
用法详解 现在完成进行时由"have/has+been+动词-ing"构成,其常见用法如下:
(1)表示从过去某时开始一直持续到现在的动作。这个动作可能刚刚停止,也可能
继续下去。此时,谓语动词为延续性动词。
Where have you been I've been looking for you everywhere.你去哪儿了?我一直
在到处找你。
(2)表示从过去某时开始到现在的一段时间内反复发生的动作,常带有感彩。
The washing machine has been running all morning. What on earth are you
washing 洗衣机已经转了一上午了。你到底在洗什么?
特别提醒 现在完成时与现在完成进行时的区别:
(1)现在完成时表示动作已完成,强调对现在的影响或产生的结果;现在完成进行
时表示动作一直在进行,可能刚刚结束,也可能继续下去,强调动作的持续性。比较:
I have written a book.我已经写了一本书。(动作已经完成)
I have been writing a book.我一直在写一本书。(动作一直在进行,可能还将继
续下去)
(2)现在完成进行时可以表示动作的反复性;现在完成时一般不表示反复性。
Have you been meeting him recently 你最近经常见他吗?(强调多次见到)
Have you met him recently 你最近见过他吗?(可能只有一次)

阅读理解(语篇类型:说明文 主题语境:人与自然——北极动物提前迁徙)
"Animals in the Arctic(北极地区), including reindeer and golden eagles, are
migrating earlier due to climate change," say researchers who have gathered a lot
of data to study the behaviour of 86 Arctic species over the past 30 years.
"We have the ability to keep our eyes on animal movements on a very large
scale(规模)," says Eliezer Gurarie at the University of Maryland."It seems that
animals are unknowingly reacting and adapting to climatic changes, and have been
doing this for years."
Gurarie and his team used GPS and satellites to track the spring migration of
more than 900 female reindeer over the past 15 years. They discover that the
females are migrating to give birth about a day earlier year on year, probably as a
result of warming temperatures."Earlier birthing times can be risky in northern parts
of the Arctic," says team member Gil Bohrer at Ohio State University."There is a
better chance of their babies facing strong and unexpected storms," he says. If they
do, many will die because they cannot deal with extreme conditions.
Similarly, golden eagles—which usually nest in the Arctic area—have been
starting their spring migration half a day earlier each year over the past 25 years.
"The day-to-day change of climate is very small," says Bohrer."To understand
how animals react to climate change, you need a very long period of observation—
something that has only recently been possible."
The researchers' archive(档案) of Arctic animal movements currently covers
more than 15 million data points related to 8,000 animals."Our archive can help
to advise management methods to preserve endangered species, as climate change
only becomes more extreme," says Bohrer.
本文是一篇说明文。文章主要介绍了,研究发现由于气候变暖,北极地区的动物迁徙
时间提前,并介绍了研究开展的过程以及此项研究的意义。
1.What can we conclude from Gurarie's words ( )
D
A.Researchers can guide animal movements.
B.Animals can adapt to climate change easily.
C.Animals don't know how to react to the environment.
D.Earlier migration is animals' reaction to warmer climate.
【解析】推理判断题。根据第二段中的"It seems that animals are
unknowingly…doing this for years"可知,从Gurarie的话可以推断出,提前迁徙是动
物对气候变暖的反应。
2.What is a possible bad effect of animals' giving birth earlier ( )
D
A.Fewer babies will be delivered.
B.They may migrate earlier in spring.
C.There will be more unexpected storms.
D.Babies have less opportunity to survive.
【解析】细节理解题。根据第三段中的"‘Earlier birthing times can be risky in
northern parts of the Arctic,'…If they do, many will die because they cannot deal
with extreme conditions"可知,早出生的动物幼崽无法抵御极端的环境状况,存活下
来的机会更少。
3.What does Bohrer want to stress in Paragraph 5 ( )
C
A.The purpose of the research.
B.The small change of climate.
C.The challenge of the research.
D.The possibility of observing animals.
【解析】推理判断题。根据第五段的内容可知,气候日复一日的变化很细微,要了
解动物对气候变化的反应,需要很长时间的观察——这是近期才得以实现的,由此
可推断,本段强调了研究的困难和挑战性。
4.What does the passage mainly talk about ( )
C
A.The observation of animals.
B.Newly-found animals in danger.
C.The discovery of animals' migrating earlier.
D.Animals' extinction caused by global warming.
【解析】本文是一篇研究报告,此类文章主旨大意一般是研究结果。根据第一段中研
究人员陈述的研究结果可知,这篇文章主要讲了北极地区的动物提前迁徙这一发现。
