六、任务型阅读
We know that many animals do not stay in one place. Birds, fish and other animals move from one place to another place at a certain time. They move for different reasons: most of them move to find food more easily, but others move to get away from places that are too crowded.
When cold weather comes, many birds move to warmer places to find food. Some fishes give birth in warm water and move to cold water to feed. The most famous migration is probably the migration of fish, which is called “salmon”(鲑鱼). This fish is born in fresh water but it travels many miles to salt water. There it spends its life. When it is old, it returns to its birthplace in fresh water. Then it gives birth and dies. In northern Europe, there is a kind of mouse. They leave their mountain homes when they become too crowded. They move down to the low land. Sometimes they move all the way to the seaside, and many of them are killed when they fall into the sea．
Recently, scientists have studied the migration of a kind of lobster(龙虾). Every year, when the season of the bad weather arrives, the lobsters get into a long line and start to walk across the floor of the ocean. Nobody knows why they do this, and nobody knows where the go. So, sometimes we know why humans and animals move from one place to another place, but at other times we don’t. Maybe living things just like to travel.
1. The reason for most of the animals to move is _____________________.
2. Find the word in the passage which means “ the movement from one place to another of a large group of animals” and write it down here: _______________.
3. The underlined word “ There” in the second paragraph refers to (指的是)________________.
4. The salmon comes back to its birthplace in order to _________________.
5. The lobsters begin to move to another place when __________________.
七、阅读理解
Monarch butterflies from eastern Canada make the most amazing journey in the insect world. Each year, this butterfly travels about 3000miles to its winter home in central Mexico(墨西哥). How can it fly so far And why does it make this long and dangerous trip Scientists still don’t have an answer.
For many years, people in Mexico wondered where the orange-and-black butterflies came from every winter. Then, in 1937, a scientist started to follow and study the butterflies. For the next 20 years, he discovered that one butterfly started its journey in Canada. Four months later, it arrived in Mexico.
The length of the butterflies find their way back to the same place Another amazing thing is that the butterflies always return to the same area in central Mexico.
How do the butterflies find their way back to the same place This is an interesting question because only every fourth generation(代)makes the trip south. In other words, the butterfly that travels to Mexico this year is the great-great-grandchild of the butterfly that traveled there last year.
Each year, four generations of a Monarch butterfly family are born. Each generation of the family has a very different life. The first generation is born in the south in late April. It slowly moves north, reproduces(繁衍), and then dies. On the trip north,two more generations are born, reproduce, and die. Each of these generations of butterflies is born. This generation has a much longer life. It lives for about eight months. This generation of butterflies makes the amazing journey back to the winter home of its great-great-grandparents. The butterflies spend the winter there, and in the spring they reproduce and then die. Their offspring will be the first generation of the next circle of life.
Today, people are still studying the Monarch butterfly. But they are not clear about everything.
1.The best title of the passage can be ________.
A.Family of Monarch butterflies
B. Mystery of Monarch butterflies
C.Monarch butterflies’ birthplace
D.Monarch butterflies’ winter home
2.It took the scientist ______ to find out that monarch butterflies came from Canada.
A. 20 years B. four months
C.five weeks D.eight months
3.We know that the _____ generation of Monarch butterflies travel back to central Mexico.
A.first B. second
C.third D.fourth
4.The underlined word “offspring” in the passage is closest in meaning to______.
A. seasons B. butterflies
C.children D.parents
5.Which statement is true according to the text
A.Monarch butterflies spend winter in eastern Canada.
B.The four generations have the same length of life.
C.Some generations die on the way north to Canada.

“I get it,” joy said.“We need the forest’s 10 for wood and paper or we might not have desks or notebooks for school.”

Ⅱ、1.A as... as与表示重量、数量、时间、距离、价格等的形容词连用时，往往不表示比较，而是构成一个形容词词组,意为“重达 ” “多达 ”“高达 ”等。as high as意为“高达 ”,故选A项。
2.D 本题可用“排除法”解答。由时间状语last winter 可知本句应用一般过去时，因此可排除A、B两项；leave for意为“动身去”,后跟目的地,故选D项。
3.B draw one’s attention意为“吸引某人的注意力”,one's可用形容词性物主代词或名词所有格两种形式，选项中只有B项为形容词性物主代词，意为“他们的”,故选B。
4.B not only... but also…“不但 而且 ”,连接主语时,谓语动词遵循就近原则;both... and...“ 和 都”，连接主语时，谓语动词用复数形式；neither…nor…“既不……也不 ”,连接主语时,谓语动词遵循就近原则;either…or…“要么 要么 ”，连接主语时，谓语动词遵循就近原则。根据关键词are可知,只有both…and…符合题意。故选B。
5.B cut off意为“切断;中断”;cut down意为“削减;砍倒”;cut up意为“切碎”;cut out意为“裁剪;删除”。根据上文中的relax yourself可知Dave需要好好休息，所以空格处表示减少活动数量， cut down 符合题意。
6.B who和whom作关系代词时指代人,其中who 在从句中可作主语、宾语或表语， whom在从句中作宾语；what不是关系词，所以它不能引导定语从句；that作关系代词时可以指人，也可以指物。当定语从句的先行词被the only修饰时，关系代词要用that。故选B。
7.A 由关键词with much difficulty并结合选项可知,此处表示“完全”变了,故用completely。
能力提升
文意概说：本文介绍了生态学的来源以及生态学家主要研究的内容。
1.B prove意为“证明”;invent意为“发明”;mark意为“标记”;accept意为“接受”。根据下句“He joined two Greek words…”可知,“ecology(生态学)”是由德国生物学家恩斯特·海克尔发明的，故选B。
2.A planet意为“行星”;building意为“建筑物”;project 意为“项目”;surface意为“表面”。根据空格后的Earth 可知，此处指我们居住的行星——地球。
3.B feeling意为“感觉”;relationship意为“关系”;distance意为“距离”;competition意为“比赛”。根据下句“The environment is an organism's surroundings.”可推知，生态学家是研究生物与其周围环境之间“关系”的科学家。
4.C pollute意为“污染”;control意为“控制”;include 意为“包括”；reduce意为“减少”。根据空格后列举的事物可知，本句介绍环境“包括”的因素。
5.D 根据空格后关键信息he thought it meant可推知,生态学家问一个男孩他认为保护环境意味着什么。
6.D wild意为“野生的”;common意为“普遍的”;wealthy意为“富有的”;important意为“重要的”。根据下句“You say they are good for... and giving shelter to…”可知，此处是指告诉砍伐者树木多么“重要”。故选D。
7.A 根据空格前的Good answer和空格后的it may not be easy to...可知,此处表示转折关系,故用but。此处表示“但要找一个伐木工谈话可能并不容易”。
8.D comfortable意为“舒服的”;tiring意为“累人的”;impossible意为“不可能的”;necessary意为“必要的”。根据下文“If we don't cut down any trees, we won't get any resources from the forest.(我们如果不砍伐树木,就不会从森林中得到任何资源)”可知，有时候砍树也是“必要的”。
9.C mystery意为“奥秘”;temperature意为“温度”;balance意为“平衡”;symbol意为“标志”。根据前文“Ecologists also study the balance of using the environment while protecting it.”可知,我们要在砍伐太多树木和不砍伐树木之间找到“平衡”。
10.B soil意为“土壤”;resource意为“资源”;landscape 意为“风景”;wildlife意为“野生动物”。根据上文“If we don't cut down any trees, we won't get any resources from the forest.”可知,我们需要从森林“资源”中获得木材和纸张。
