Is there intelligent (有智力的) life on other planets? For years, scientists said “no.” or “we don’t know.” But today this is changing. Seth Shostak and Alexandra Barnett are astronomers(天文學家). They believe intelligent life exists (存在) somewhere in the universe. They also think we sill soon contact these beings(人；生物).
Why do Shostak and Barnett think intelligent life exists on other planets? The first reason is time. Scientists believe the universe is about 12 billion years old. “This is long enough for other planets to have intelligent life,” say Shostak and Barnett. The second reason is size—the universe is huge. “Tools like the Hubble Telescope(哈勃望遠鏡) have shown that there are at least 100 billion galaxies,” says Shostak. “And our galaxy, the Milky Way, has at least 100 billion stars. Some planets going around these stars might be similar to Earth.”
In the past, it was hard to look for signs of intelligent life in the universe. But now, powerful telescopes(高倍望遠鏡) allow scientists to discover smaller planets—the size of Mars or Earth—in other solar systems. These planets might have intelligent life.
Have beings from space already visited Earth? “Probably not,” says Shostak. “It’s a long way away. However, intelligent beings may contact us in other way, such as radio signals(信號). In fact, they may be trying to communicate with us now, but we don’t have the right tools to receive their messages. However, this is changing. By 2025, we could make contact with other life forms in our universe and we might help each other.”

A．astronomers

D．drivers

小題2:What is the best title for Paragraph 2?

A．The Age and Size of Earth

A．There were not any smaller planets.

B．There were not any powerful telescopes.

C．The astronomers were not interested in them.

D．The Milky Way didn’t exist at that time,

小題4:Why haven’t beings from space visited us yet according to Shostak?

A．They’re afraid of us.

B．It’s a long way away.

C．They don’t want to see us.

D．They don’t know how to use radio signals.

小題5:What does the underlined phrase “life forms” in the last paragraph mean?

B．Tools

C．Intelligent beings

D．Radio signals

小題1:A

試題分析：本文敘述了科學家認為其他星球也存在智能生命，因為宇宙形成的時間這么長，足夠其他星球形成生命；其次宇宙這么大，周圍會有跟地球相似的星球。不久來自太空的生命有可能將會和我們聯系，我們可能到2025年，也會和他們取得聯系，我們可能會互相幫助。
小題1:細節理解題。根據Seth Shostak and Alexandra Barnett are astronomers(天文學家)可知Seth Shostak 和Alexandra Barnett是天文學家。故選A。
小題2:標題歸納題。根據Why do Shostak and Barnett think intelligent life exists on other planets?可知本文主要解釋為什么認為在其他星球上可能有智能生命存在，故選C。
小題3:推理判斷題。根據In the past, it was hard to look for signs of intelligent life in the universe. But now, powerful telescopes(高倍望遠鏡) allow scientists to discover smaller planets可知在過去沒有像現在一樣的高倍望遠鏡，因此很難再宇宙中尋找到智能生命的跡象。故選B。
小題4:推理判斷題。根據“Probably not,” says Shostak. It’s a long way away.可知Shostak.認為來自太空的生命可能沒有來過地球，因為路途遙遠。故選B。
小題5:詞義猜測題。根據 However, intelligent beings may contact us in other way, 可知智能生命可能會用其他方式聯系我們，故推測此處的life forms指的是intelligent beings，故選C。

Over 30% of the natural world has been seriously destroyed by humans (人類) over the last 30 years. This is because the number of people living on Earth is nearly six billion (十億). All of these people need food, space and energy. As a result, lots of Earth’s natural resources will be used up. When we destroy our earth to get natural resources such as wood or oil, animals often lose their living space. They cannot have enough food, and they will get hurt or die.
The World Wide Fund for Nature (WWF) is an international charity. It tries to prevent humans from destroying more of nature than is necessary. For example, in China WWF is working with the local government to reconnect (重新連接) some small lakes in Anhui Province to the Yangtze River and to create(創造) more protected areas so that China’s natural beauty will not be lost in the future. WWF works in more than 50 countries, saving rainforests and stopping hunters from killing rare animals and protecting traditional ways of life in areas where they are in danger of being lost. WWF’s main goal is to encourage development that does not harm the environment and the animals that live in it. Even though the charity is known all over the world, and a lot of people support the goals of WWF, not so many donate money often. This makes it difficult for the charity to do all the things it wants to do.
小題1:Why has over 30% of the natural world been destroyed?

A．Because hunters are killing rare animals.

小題3:What is WWF’s main goal?

A．To save rainforests.

B．To stop hunters killing rare animals.

C．To get more people to donate money.

D．To protect the environment while developing.

小題4:Why is it difficult for WWF to do all the things they want to?

B．Because WWF doesn’t have enough money from donations

C．Because there are too many problems for them to solve.

D．Because WWF doesn’t encourage development.

School education(教育) is very important and useful. Yet, no one can learn everything from school. A teacher, no matter how much he knows, can not teach his students everything they want to know. The teacher’s job is to show his students how to learn. He teaches them how to read and how to think. So, much more is to be learned outside school by the students themselves.
It is always more important to know how to study by oneself than to memorize some facts or a formula（公式）. It is actually quite easy to learn a certain fact in history or a formula in math. But it is very difficult to use a formula in working out a math problem.
Great scientists didn’t get everything from school. For example, Edison didn’t even finish primary school. But they were all so successful. They invented so many things . The reason for their success was that they knew how to study. They read books that were not taught at school. They would ask many questions as they read. They did thousands of experiments. They worked hard all their lives, wasting not a single moment. Above all, they knew how to use their brain.
小題1: According to the passage, the most important thing a teacher should do is _______.

A．to teach his students everything he knows

B．to teach the students how to think

C．to know everything they want to know

D．to teach the students how to work out a math problem

小題2: To work out a math problem, you need to know _________.

A．a certain formula	B．a certain fact
C．some facts	D．the way to solve it

小題3: Which of the following is NOT true?

A．Great scientists read a lot of books and asked many questions while reading.

B．Great scientists did thousands of experiments.

C．Great scientists always worked hard and never wasted time.

D．Great scientists got everything from school.

小題4: The passage is written mainly to tell us .

A．how to memorize some facts or a formula（公式）

B．who the great scientists are

C．How to study

D．why Edison didn’t finish primary school

As young students, you have many dreams. These dreams can be very big, such as winning the Noble Prize; they can also be small, such as becoming one of the best students in your class. Once you find a dream, what do you do with it? 小題1:
Andrew Matthews, an Australian writer, tells us that making your dreams real is life’s biggest challenge. You may think you’re not very good at some school subjects, or that it’s impossible for you to become a writer. 小題2:
小題3: The first thing you must do is to remember what your dream is. Don’t let it leave your heart. Keep telling yourself what you want every day and then your dream will come true faster. You should know that a big dream is, in fact, made up of many small dreams.
小題4:There will be difficulties on the road to your dream. But the biggest difficulty comes from yourself. 小題5: Studying instead of watching TV will help you get better exam results, while saving five yuan instead of buying an ice cream means you can buy a new book.
As you get closer to your dream, it may change a little. This is good as you have the chance to learn something more useful and find new hobbies.

C
Why are you study habits different from those of your friends? Why do you seem to learn faster in some classes while more slowly in others? One reason you may not know is that people have different types. Scientists say there are three different learning types: Visual(視覺型)，Auditory(聽覺型)，and Kinesthetic (動覺型)。
Visual learners learn best by seeing. If you seem to easily remember information from pictures, graphs(圖表)，and videos, you are probably a visual learner. You’re not good at copying down what the teacher says in class. Never mind. You can draw graphs or pictures instead, if you find that works better for you.
Auditory learners learn best by hearing. If you seem to easily remember things by hearing them, then you are probably an auditory learner. You must listen carefully while the teacher is speaking because it’s the easiest way for you to learn . Sometimes you may find that taking notes tops you from listening carefully. After class, you can write down what you remember or borrow your friend’s notes to copy.
Kinesthetic learners learn best by doing. If you seem to learn best by working with your hands, you are probably a kinesthetic learner. Taking notes by writing can make you pay close attention to information as you receive it. Of course, you can learn best by making full use of labs or other class activities.
Hope you learn better by knowing what your personal learning type is.
小題1:There are____________ different learning types according to the passage.

A．two

B．three

C．four

D．five

小題2:Jude can remember the words of a song quickly by listening to it once or twice. She might be a /an ____________ according to the passage.

A．auditory learner	B．visual learner
C．strange leaner	D．usual learner

小題3:Kinesthetic learners learn best by ____________

A．Remembering information from videos	B．listening teachers in class
C．drawing graphs or pictures	D．doing things with their hands

小題4:The best title of this passage may be “____________”

A．Study Habits	B．Ways to study
C．Learning types	D．Reasons to learn

The father’s role in the family is important. One researcher says babies who are cared for by their fathers have greater cognitive (認知的) development at one year of age than babies not cared for by their fathers. Another researcher reports that by spending time with their pre-school children, fathers can help to develop children’s language ability. Researchers also point out that for school-age children, fathers are one bridge with the outside world.
