【题目】 Air pollution is a big problem for cities. Many people are dying from it. But how can we tell the air quality(质量) is good or bad?

Joris Lam has invented a birdhouse that can tell us about the air quality. On a tree next to a canal (运河) in Amsterdam, a small birdhouse will shine bright green when the air is clean. If you are standing near the birdhouse, it will also give you a free Wi-Fi connection. So Joris’s birdhouse is called TreeWifi. It can be put on a tree around your house to test the air quality. People can see a screen with information about local air quality and how to improve it. TreeWifi is a simple way for people to know about the air pollution around them. If the birdhouse doesn't shine, people will care more about the environment. It tells them to change their lifestyles. For example, to protect the air, they can ride bikes instead of driving cars.

Joris and his team are trying to make some changes to the birdhouse. In the future, the heat of its green light will be used to keep birds warm in winter.

12题完成句子;3题简略回答问题;4题找出并写下第二段的主题句;5题将文中画线句子译成汉语。

4Joris Lam has invented a birdhouse that can tell us about the air quality.

5如果鸟舍不发光,人们就要更加关心环境。

【解析】

文章大意:这是一篇科普类说明文,文章首先指出空气污染的严重性,荷兰设计师Joris Lam创造出能够检测出环境污染的新发明——free Wi-Fi connection. 这是一个让人们了解周围空气污染的简单方法。 如果鸟舍不发光,人们就会更加关心环境。它告诉他们改变生活方式。将来,它的绿光的热量将被用来在冬天给鸟取暖。

1细节理解题。根据“Air pollution is a big problem for cities. Many people are dying from it.”“ 空气污染是城市的大问题。许多人正为此而死”可知,故答案为air pollution

2细节理解题。根据“a small birdhouse will shine bright green when the air is clean.” 当空气清新时,一个小鸟舍会发出明亮的绿色光。可知,故答案为clean

3细节理解题。根据“If you are standing near the birdhouse, it will also give you a free Wi-Fi connection.”如果你站在鸟舍附近,它也会给你一个免费的Wi-Fi连接是其得名原因,故答案为Because it will also give you a free Wi-Fi connection (when you are standing near the birdhouse).

4主旨大意题。根据文章首先指出空气污染的严重性,后面又介绍了创造出能够检测出环境污染的新发明——free Wi-Fi connection.因此,“Joris Lam has invented a birdhouse that can tell us about the air quality.”是全文的中心句,起到承上启下的作用,故答案为Joris Lam has invented a birdhouse that can tell us about the air quality.

5英译汉。此句是条件状语从句,主将从现。根据从句If the birdhouse doesn't shine,如果鸟舍不发光;主句people will care more about the environment. 人们就要更加关心环境。故答案为如果鸟舍不发光,人们就要更加关心环境。

【题目】 Do you want to know something about the history of weather? Don't look at the sky. Don't look for old weather reports. Looking at tree rings is more important. Correct weather reports date back only one century, but some trees can provide an exact record of the weather even further back.

It is natural that a tree would grow best in a climate with plenty of sunlight and rainfall. It is also expected that little sunlight or rainfall would limit the growth of a tree. The change from a favorable to an unfavorable climate can be determined by reading the pattern of rings in a tree trunk. To find out the weather of ten years ago, count the rings of a tree trunk from the outside to the inside. If the tenth ring is far from the other rings, then it is certain that plenty of sunny and rainy weather occurred. If the rings are close together, then the climate was bad for the tree.

Studying tree rings is important not only for the history of weather, but also for the history of man. In a region of New Mexico you can find only sand--no trees and no people. However, many centuries ago a large population lived there. They left suddenly. Why?

A scientist studied patterns of dead tree rings which had grown there. He decided that the people had to leave because they had cut down all the trees. Trees were necessary to make fires and buildings. So, after the people destroyed the trees, they had to move.

In this instance studying tree rings uncovered an exciting fact about the history of man.

1It is understood that in a favorable climate____________.

A.tree rings grow close together

B.tree rings grow far apart

C.trees in New Mexico will grow big and tall

D.people can cut down most of the trees in New Mexico

2Why did ancient people usually live where there were plenty of trees?

A.Trees provided them with shades.

B.Trees indicated plenty of sunlight and rainfall.

C.Trees were materials for cooking and building houses.

D.Trees provided them with fruit and food.

3Scientists are interested in studying tree rings because they can tell__________.

A.a lot about what happened in history.

B.whether a particular tree was healthy or not.

C.whether people took good care of the trees or not.

D.how old the trees were.

4By studying the dead tree rings in Mexico the scientist found out____________.

A.where the people had to go

B.what the people had to eat

C.how the people left

D.why the people had to leave

5The people had to leave the region of New Mexico because__________.

A.they had cut down all the trees

B.there were many trees there

C.they had no water

D.bad weather stopped the growth of trees

【题目】 “What’s the name of the supermarket? I can’t remember right now.” Have you ever heard your grandparents ask questions like this sometimes? Usually, we think that older people’s memory becomes had because their brains get weak. But now a team of scientists at the University of Tubingen in Germany has a new idea. “The human brain works slower in old age,” says Michael Ramscar, the team’s lead scientist, “only because it has stored more information over time.” The findings are based on a series of computer tests related to learning and memory.

Scientists had the computers read a certain amount of words and learn new things each day. When the computer “read” a small amount of data(数据),its performance on cognitive(认知)tests was similar to that of a young adult . But if the computer took in larger amounts of data, its performance was similar to that of an older adult. Often it was slower, but not because its processing ability had dropped. Rather, increased “experience” had caused the computer’s database to grow, giving it more data to process-which takes more time. This is similar to how old people process information.

Imagine that one person knows just two people’s birthdays and can get them right each time he or she is asked. Another person knows the birthdays of 2,000 people , but can only match the right person to the right birthday 9 times out of 10. Can you say the first person has a better memory than the second person?

“The larger the library you have in your head , the longer it usually takes to find a particular word,” Benedict Carey, a science reporter for The New York Times, wrote in an article about the study.

【题目】 More than its influence on health, not getting enough sleep can lead to car accidents or other mistakes. Here are what sleep researchers have found about how to sleep.

How much sleep do we actually need?

It is known that all of us naturally need no less than 8 hours of sleep per night. When we sleep below six hours per 24, we’re at an increased risk of health problems. Some of us think we can make up any of those hours lost during the week on the weekends. Suddenly there is no storage system for sleep in the brain.

Can we train ourselves to need less sleep?

As a study in 1964, a 17- year- old boy named Randy Gardener stayed awake for 264 hours. How many people could do anything close to that without dying?

When you are reading this, you might say you usually get 6 hours of sleep and feel just fine . Sleep experts often compare people without enough sleep to drunk drivers: They don't get behind the wheel thinking .They are probably going to kill someone.

Can we drink coffee instead of sleeping?

Coffee can keep us awake. Remember, too much coffee may throw off our sleep and energy cycles. So avoid caffeine for 4 to 6 hours before bedtime.

Does a sense of purpose connect with sleep quality?

A new research suggests a kind of strong connection between purpose in life and sleep. People who have a great sense of purpose usually have better physical and mental health, which in turn explains their higher quality sleep. Perhaps developing a sense of purpose in life could be as useful at improving sleep as the healthy habits above.

【题目】 When our son Peter was twelve, the new bicycle he had received was stolen. Owning a bicycle was big fun to our children when they were little. They spent hours and hours, day after day, on their bicycles, riding up and together as a family a lot. Bicycling was a great way to get the kids out of the house and into the fresh air without spending the money.

When Peter and his sister went outside for a morning ride, he discovered that his bicycle had been stolen from our backyard. He couldn't believe that someone would do this.

He got a large piece of cardboard, painted a sign begging for the bicycle to be returned, and tied the sign to the letterbox. The following morning, when I went out to collect the mail, I found a white envelope with the magical words, "Buy yourself a new bicycle". There was a $ 100 banknote inside.

We were very touched that someone had the heart to do this. We'd never been able to thank the person but we guessed that it may have been one of our wonderful neighbors. Peter painted a big "Thank you!" on the sign and we left it outside for a couple of weeks afterwards, hoping the kind stranger would drive down our street and see it.

Peter was able to own a new bicycle again. As the years went on, the bicycle became older but remained just as important as before. Now Peter is 25.

All these years later we are still thankful for the stranger's kindness. We were a young family with three little children and it meant a lot to us. We still talk about it and, even now, wonder who the kind stranger was.

根据短文内容,回答问题。

1What did Peter often do when he was a child?

2Where was the bicycle stolen?

3How did the family feel after someone had the heart to give them the $ 100 banknote?

4Why did Peter put the 'Thank you' sign outside?

5Did the writer and the family remember or forget the stranger's kindness?
