There is usually only one main gate in each Tulou and up to (至多)80 families can live in it. It is like a small city.

Have you ever wondered why birds sing? Maybe you thought that they were just happy.  After all,you probably sing or whistle when you are happy.
Some scientists believe that birds do sing some of the time just because they are happy. However,they sing most of the time for a very different reason. Their singing is actually a warning to other birds to stay out of their territory.
Do you know what a ’territory’ is? A territory is an area that an animal,usually the male,claims(聲稱)as its own. Only he and his family are welcome there. No other families of the same kind are welcome. Your garden and house are your territory where only your family and friends are welcome. If a stranger should enter your territory and threaten(威脅)you,you might shout. Probably this would be enough to frighten him away.
If so,you have actually scared the stranger away without having to fight him. A bird does the same thing. But he expects an outsider almost any time,especially at nesting(筑巢)season. So he is screaming all the time,whether he can see an outsider or not. This screaming is what we call a bird’s song,and it is usually enough to keep an outsider away.
Birds sing loudest in the spring when they are trying to attract a mate and warn others not to enter the territory of theirs..
You can see that birds have a language of their own. Most of it has to do with attracting mates and setting up territories.
小題1: Some scientists believe that most of the time bird’s singing is actually _______.
A.away of warningB.an expression of happiness
C.an expression of angerD.away of greeting
小題2:What is a bird’s "territory"?.
A.A place where families of other kinds are not accepted.
B.A place where a bird may shut at the top of its voice
C.An area for which birds fight against each other.
D.An area which a bird considers to be its own.
小題3: Why do birds keep on singing at nesting season?
A.Because they want to invite more friends.
B.Because they want to find outsiders around.
C.Because their singing helps frighten outsiders away.
D.Because their singing helps remove their fears.
小題4:How does the writer explain bird’s singing?
A.By comparing birds with human beings.B.By reporting experiment results.
C.By describing birds’ daily life.D.By telling a bird’s story.

Television has a huge influence on our lives. It is one of the most important ways of getting information. People spend part of their spare time watching television, and much of what they learn comes from it.

Thinking is something you choose to do as a fish chooses to live in water. To be human is to think. But thinking may come naturally without your knowing how you do it. Thinking about thinking is the key to critical(批判性的) thinking. When you think critically, you take control of your thinking processes(過程). Otherwise, you might be controlled by the ideas of others. Indeed, critical thinking is at the heart of education.
The word “critical” here has a special meaning. It does not mean taking one view against another view, as when someone criticizes another person for doing something wrong. The nature of critical thinking is thinking beyond the easily seen--beyond the pictures on TV, the untrue reports in the newspapers, and the faulty reasoning.
Critical thinking is an attitude as much as an activity. If you are interested in life and want to dig deeper into it, you are a critical thinker. If you find pleasure in deep thinking about different ideas, characters, and facts, you are a critical thinker.
Activities of the mind and higher-order reasoning(推理)are processes of deep and careful consideration. They take time, and do not go hand in hand with the fast speed in today’s world: fast foods, instant coffee, and self-developing film. If you are among the people who believe that speed is a measure(尺度)of intelligence(智慧), you may learn something new from a story about Albert Einstein. The first time Banesh Hoffman, a scientist, was to discuss his work with Albert Einstein. Hoffman was too nervous to speak. But Einstein immediately made Hoffman feel comfortable by saying, “Please go slowly. I don’t understand things quickly.” 
小題1:Critical thinking is important to us because if we do not think critically, _______.
A.it will be hard for us to think naturally and fast
B.we might be controlled by other people’s ideas
C.we will follow the ideas of others naturally
D.we might be fooled by other people’s ideas
小題2:If you are a critical thinker, you will ________.
A.take one view against another view
B.trust the reports in the newspapers
C.think deeply about different ideas
D.criticize other people for their mistakes
小題3: In the last paragraph, “something new” suggests that ________.
A.speed can improve intelligence
B.intelligence is not decided by speed
C.the smarter you are, the faster you do things
D.the faster you do things, the smarter you become

Teachers say the digital age has had a good and a not-so-good influence on the American teenagers. More than 2,000 high school teachers took an online survey.
75 percent of the teachers said the Internet and digital search tools have had a “mostly good” use for their students' research habits and skills, But 87 percent agreed that these technologies "make the students not have enough attention.” And 64 percent said the technologies “do little to help them in courses.”
Judy Buchanan is a director of the National Writing Project. Ms. Buchanan says digital research tools are helping students learn more, and learn faster. Teachers really like these tools, because they are ways to make some of learning exciting. Young people enjoy using these tools. And the goal is to help them become creative students of meaningful work, and not just that kind of copyist.
But one problem the survey found is that many students don't have a good understanding of how to use the digital knowledge well. In other words, they trust(信任) too much of the information. Judy Buchanan says these students have not developed the skills they need to tell whether the online information is good or bad.
Another problem the survey found is something that might not seem like a problem, at all, being-able to quickly find information online. Teachers say the ability of their students to work hard to find answers is becoming weaker. They say students depend too much on search engines (引擎) and do not make enough use, of printed books or research, librarians.
Besides, many teachers are also worried about the problem that the Internet makes it easy for students to copy work done by others, instead of using their own abilities.
小題1:      of the teachers agreed technologies may stop students from having enough attention.
A.50%B.64%C.75%D.87%
小題2: How many problems are mentioned (提及) in the passage'?
A.OneB.Two.C.Three.D.Four.
小題3:Teachers like the digital search tools because they can        .
A.make some of learning exciting
B.help students find answers easily
C.tell whether the information is good or not
D.help students copy the work done by others
小題4:What does the writer want to tell us by writing this passage?
A.Digital search tools have quite a lot of advantages.
B.Students don't know how to use the digital search tools.
C.Many teachers are worried about the students' abilities.
D.Students should learn how to use the digital tools in a right way.
