One day，Mr.Arnold was teaching a lesson，and things were going as normally as ever.He was explaining the story of mankind to his pupils.He told them that，in the beginning，men were nomads(游牧人)；they never stayed in the same place for very long.Instead，they would travel about，here and there，in search of food，wherever it was to be found. And when the food ran out，they would move off somewhere else.

He taught them about the invention of farming and keeping animals.This was an important discovery，because by learning to cultivate(耕作)the land，and care for animals，mankind would always have food steadily available.It also meant that people could remain living in one place，and this made it easier to set about tasks that would take a long while to complete，like building towns，cities，and all that were in them.All the children listening were attracted by this story，until Lucy jumped up：

“And if that was so important and improved everything so much，why are we nomads all over again，Mr.Arnold？”

Mr.Arnold didn't know what to say. Lucy was a very intelligent girl.He knew that she lived with her parents in a house，so she must know that her family were not nomads；so what did she mean?

“We have all become nomads again，” continued Lucy.“The other day，outside the city，they were cutting the forest down. A while ago a fisherman told me how they fish.It's the same with everyone：when there's no more forest left, the foresters go elsewhere，and when the fish run out, the fishermen move on.That's what the nomads did，isn't it？”

The teacher nodded,thoughtfully. Really,Lucy was right. Mankind had turned into nomads. Instead of looking after the land in a way that we could be sure it would keep supplying our needs，we kept developing it until the land was bare.And then off we would go to the next place！ The class spent the rest of the afternoon talking about what they could do to show how to be more civilized.

The next day everyone attended class wearing a green T?shirt，with a message that said，“I am not a nomad！”

And，from then on，they set about showing that indeed they were not.Every time they knew they needed something，they made sure that they would get it using care and control.If they needed wood or paper，they would make sure that they got the recycled kind.They ordered their fish from fish farms，making sure that the fish they received were not too young and too small.They only used animals that were well cared for，and brought up on farms.

And so，from their little town，those children managed to give up being nomads again，just as prehistoric men had done so many thousands of years ago.

1.Why would early humans travel about in the beginning?

A．To experience different lifestyles.

B．To go sightseeing in different places.

C．To find what they could to feed themselves.

D．To do more exercise to build themselves up.

2.In the teacher's opinion，Lucy's argument was________.

C．Fishermen move elsewhere when there is no fish left.

D．Foresters leave the place where wood is not available.

169 junior 1 students at No. 35 Middle School of Shenyang took their first no­teacher exam. After the teacher handed out the exam paper, he left the room and never came back. A student collected the papers when the exam ended.

“That test was not only a test of knowledge, but also a test of moral (道德). We wanted to show students how important honesty is，” said Cai Wenguo, the school's headmaster. The school says no cheating happened in the test. Next year, it wants 80% of its exams to be without teachers. But students have different ideas.

“I was happy and excited during the exam because my teachers trusted me，” said Lang Yudan, a 13­year­old girl in Class 11.

“Schools must trust students a lot not to use invigilators (監(jiān)考人). But I think it is too early. Some students will cheat if there are no invigilators. And the students will not be able to ask for help when needed，” said Hua Sha.

“I don't like having invigilators in exams. When they walk around the classroom, they make me nervous. I would get higher marks without them in the room because I would feel more relaxed，” Liu Qingxi said.

“I think it's very important to have invigilators in exams. Many students want to check their answers with each other after they have finished papers. And they can also keep the classroom in order when something unusual happens. They may make me nervous, but I still think we need them，” Shangguan Yuan said.

Not using invigilators may be a good idea. But before using it, schools must tell students the importance of honesty and try to find ways to solve something unusual in exams.

1.The passage mainly talks about________.

A．how to pass an exam

B．how to make students honest

C．whether there is cheating in exams

D．whether invigilators are needed in exams

2.No. 35 Middle School of Shenyang held a no­teacher exam to________.

A．let the students have a good test

B．teach the students in a better way

C．help all the students pass the exam

D．find whether the students were honest

3.From what the students have said, we know________.

A．invigilators really help them a lot

B．a(chǎn)ll of them think it is a good idea

C．something unusual never happens in exams

D．not all of them agree with the headmaster

4.What does Hua Sha think of no­teacher exams?

A．It's a good idea to have no­teacher exams but something must be done first.

B．If there are no invigilators, the students will certainly get lower marks.

C．Exams without invigilators will never be held since students are not honest.

D．She thinks it's the best way to show that schools trust their students a lot.

Good readers know that reading isn’t just about knowing words — it’s a way of thinking. Smart readers think before, during and after reading. Here are some tips that may be of some help.

Think before you read. Before you read the text, ask yourself the questions why you are reading it and what you want to get from it. Answering the questions will help you choose what words you need to know and what words you can skip or scan.

Think while you are reading. Can you get the meaning of the text without looking up new words in a dictionary? Are there any clues in the text? A text will often give examples that may help you understand what some of the words mean. Let’s take the following sentence for example: Many large Russian cities, such as Chelyabinsk and Irkutsk, have taken steps to protect their culture. The words “Chelyabinsk” and “Irkutsk” may be new to us, but the sentence tells us that they are examples of ______.

Think after you read. Do you understand the text? What is the main idea of the text? Can you guess the meaning of the new words? Which words do you need to look up? Is the text too easy or too hard for you?

If you practice reading and thinking in this way you will become a smarter reader and you will learn faster and better.

1.This passage is probably taken from _______.

A. a newspaper for general readers

B. a magazine for language teachers

C. a book for language learners

D. an advertisement for a new book

2.Which of the following can best be put in the blank in the passage?

A. countries B. mountains

C. rivers D. cities

科目：高中英語 來源：2016-2017學(xué)年江蘇南通中學(xué)高二10月考英語試卷（解析版） 題型：閱讀理解

Mountaineers have noted that as they climb, for example, up to the 12,633?foot Humphreys Peak in Arizona, plant life changes greatly. In the Sonoran Desert, one climbs into a pine forest at 7,000 feet and a treeless tundra(凍土帶) on the top of the mountain. It may seem that plants at a given altitude are associated in what can be called “communities” －groupings of species. The idea is that over time, plants that require particular climate and soil conditions come to live in the same places, and are frequently to be found together. Scientists study the history of plant life and build up a picture of how groups of plants have responded to climate changes and how ecosystems develop. But are these associations, which are real in the present, permanent?

A great natural experiment took place on this planet between 25,000 and 10,000 years ago, when small changes in the earth’s orbit caused great sheets of ice to spread from poles. These glaciers(冰川) covered much of North America and Europe to depths of up to two miles, and then, as the climate warmed, they retreated. During this retreat, they left behind newly uncovered land for living things to occupy, and as those living things moved in they laid down a record we can read now. As the ice retreated and plants started to grow near a lake, they release pollen(花粉). Some would fall into the lake, sink to the bottom and mix with the sand. By drilling into the lake bottom it is possible to read the record of the plant life around the lake. The fossil record seems clear; there is little or no evidence that entire groups of plants moved north together. Things that lived together in the past don’t live together now, and things that live together now didn’t live together in the past. Each individual living things moved at its own pace. The fossil record seems to be telling us that we should be thinking about preserving species by giving them room to move about－to respond to environmental changes.

1.According to the passage, the movement of individual species of plants ________.

A. occurs in groups

B. often depends upon the formation of lakes

C. does not occur in groups

D. depends upon climate and soil conditions

2. All of the following are true EXCEPT ________.

A. The ice age occurred when there were small changes in the orbit of the earth

B. fossil records seem to indicate that plants will be preserved if they have enough room to move

C. fossil records clearly show that entire groups of plants are unlikely to have moved together

D. in the ice age glaciers covered the world to depths of up to two miles

3.The underlined word “which” refers to ________.

A. the responses of plants to climate changes

B. the current theories of ecosystems

C. the development of ecosystems

D. plant life changes

4.The second paragraph is intended to ________.

A. support the main idea of the first paragraph

B. answer the question raised in first paragraph

C. make suggestions about responding to environmental changes

D. stress the importance of preserving species
