三、阅读单选
Last week，Chicago became the first city in the US to join the “Lights Out Plan”．People turned off the lights in the city's tallest buildings so that thousands of birds could get to their winter homes.Every year in autumn，some birds fly over Chicago on their way to the south and come back the next spring.
Lights mean danger to birds.Birds find their way by looking at the stars in the sky.Lights in tall buildings are so bright that birds may mistake them as stars.This means they can not find the right way to go home.
This month，about 300 types of birds are flying over Chicago to go back to the south to live through the cold winter.
Birds fly to warmer places for a few reasons.Many birds cannot live in the cold，so they fly to warmer places.But there are other reasons，too.Birds need to look for food in the south.Another reason is that they want to have baby birds.Many birds like to have their baby birds in the same “house” they lived in last year，so they fly back there.
There are about 9，000 kinds of birds in the world，and about 600 kinds of birds migrate．Some birds can fly a very long way.Sometimes they fly to other countries.We have fewer birds today because there are fewer places for birds.
16．Why did people in Chicago turn off the lights in the city's tallest buildings last week
A．Because people wanted to save money.
B．Because people were afraid that birds would lose their way.
C．Because people were afraid that birds would make much noise.
17．What does the underlined word “migrate” mean in Chinese
A．迁徙 B．定居 C．冬眠
18．Today we have fewer birds because ________.
A．lots of birds are often ill
B．people kill lots of birds
C．there are fewer places for birds
19．Which of the following statements is NOT true
A．All birds fly to warmer places every year.
B．Some birds have to fly to warmer places in autumn.
C．Some birds can fly a long way to other countries.
【答案】
16．B
17．A
18．C
19．A
【分析】
文章大意：上周，芝加哥成为第一个在美国加入"熄灯计划"的城市。人们关掉城市高楼大厦的灯光，是为了使成千上万的鸟儿可以找到他们冬天的家。灯光对鸟类意味着危险，鸟儿通过看天上的星星找到路，高楼大厦里的灯光如此明亮以至于鸟儿们误以为它们是星星，这意味着它们找不到回家的路。世界上约有鸟类9000种，约600种的鸟类迁徙。今天我们的鸟越来越少，因为供鸟栖息的地方越来越少了。
16．细节理解题，根据文中的句子People turned off the lights in the city's tallest buildings so that thousands of birds could get to their winter homes.可知，人们之所以关掉这座城市高楼大厦的灯光，是为了让鸟儿找到回家的路，也就是他们担心鸟儿们会迷路；故答案选B。
17．词义理解题。根据"Some birds can fly a very long way．Sometimes they fly to other countries．"可知有的鸟儿每年都会飞很远的距离，有的甚至要飞到其他国家去；可推知本句是在讲许多种鸟类要飞到外地进行迁徙，所以migrate意思应该是“迁徙”，故答案选A。
18．细节理解题．根据"We have fewer birds today because there are fewer places for birds．"可知现在有更少的鸟是因为适合鸟儿生活、生存的地方越来越少了；故答案选C。
19．理解判断题。根据There are about 9，000kinds of birds in the world，and about 600kinds of birds migrate（迁徙）可知不是所有的鸟都迁徙，只有部分，所以A选项是错误，故答案选A。

【答案】are shopping
【详解】
句意：看！他们正在网上购物。根据“Look!”可知，句子要用现在进行时，主语是they，be动词应用are，故填are shopping。
21．Can you tell me the _______ (advantage) of the machine
【答案】advantages
【详解】
句意：你能告诉我这台机器的优势吗？机器的优势不止一个，故这里填可数名词“优势”advantage的复数形式 advantages。
22．—Do you know Mr. White well
—Yes. He ______________ （work） for the WWF for two years.

We need to start living more responsibly-but how One answer is to upcycle (再生利用). I started upcycling clothing. Making new things out of old clothes is the best way to mix my talent and my interest. Do you upcycle If so, what new things have you made If not, why not give it a try What do you think of the “new” hat I made for my sister It used to be my mum’s sweater.

We need to start living more responsibly-but how One answer is to upcycle (再生利用). I started upcycling clothing. Making new things out of old clothes is the best way to mix my talent and my interest. Do you upcycle If so, what new things have you made If not, why not give it a try What do you think of the “new” hat I made for my sister It used to be my mum’s sweater.

One possible version:
Food is important to us. It’s our duty to save food. Today food waste is a big problem. Once, while I was eating lunch at the school dining hall, I suddenly found that the student beside me threw his meal away without saying a word. He didn’t even finish half of it.
In my opinion, it is so wasteful to do that, because it is not easy for farmers to grow food nowadays. Besides, many people in the world die of hunger every day, and they don’t have enough food to eat.
In order to stop food waste, I have some ideas to share with you. First, do not order the food more than you can eat while eating outside. It is necessary to save food. Second, try your best to save food at home as much as possible so that many people in the world can be helped. What’s more, if you can’t finish eating what you order in the restaurant, you can take it away instead of wasting it.
All in all, we need to form a good habit of eating food and make our world a better place.
Yours,
Li Hua

1. litter n. 垃圾 v. 乱扔
（1）litter作名词相当于rubbish，是不可数名词。
（2）litter作动词用意为＂乱扔＂。
2. cut down 削减；砍倒

not only ...but also... 意为＂不但……而且……＂，其中also可以省略。not only...but also...是并列连词词组，可连接相同的句子成分或并列成分。连接并列主语时，句子的谓语动词应与but also后的主语的人称和数保持一致。

take part in中的in为介词，后接名词、代词或动词的-ing形式。

三、阅读单选
Last week，Chicago became the first city in the US to join the “Lights Out Plan”．People turned off the lights in the city's tallest buildings so that thousands of birds could get to their winter homes.Every year in autumn，some birds fly over Chicago on their way to the south and come back the next spring.
Lights mean danger to birds.Birds find their way by looking at the stars in the sky.Lights in tall buildings are so bright that birds may mistake them as stars.This means they can not find the right way to go home.
This month，about 300 types of birds are flying over Chicago to go back to the south to live through the cold winter.
Birds fly to warmer places for a few reasons.Many birds cannot live in the cold，so they fly to warmer places.But there are other reasons，too.Birds need to look for food in the south.Another reason is that they want to have baby birds.Many birds like to have their baby birds in the same “house” they lived in last year，so they fly back there.
There are about 9，000 kinds of birds in the world，and about 600 kinds of birds migrate．Some birds can fly a very long way.Sometimes they fly to other countries.We have fewer birds today because there are fewer places for birds.
