【題目】根據(jù)短文理解，選擇正確答案。
A telescope, called Gaia, is being designed by astronomers in Europe, and it couldn't be more different from Pan-STARRS, which is another telescope being designed. While Pan-STARRS will be looking for asteroids (小行星) and comets headed for Earth, Gaia will be looking at our entire galaxy (銀河系).
Gaia is designed to draw a map of the Milky Way, our home galaxy. Just as a map of your town gives you a picture of where things are located, Gaia's map of the galaxy will tell astronomers where the stars are. Over five years, Gaia will observe (觀察) about a billion stars and other objects in our galaxy. Each object will be observed about 70 times.
Gaia will be sent into space connected to a rocket. It contains two telescopes, each focused at a different angle (角度). These two telescopes act like Gaia's “eyes”. The reason why humans can see things in 3D is that we have two eyes focused on the same object, at slightly different angles. By using two telescopes like eyes, Gaia can produce the first 3D map of the positions of the stars it views.
Gaia, which is to be sent into space, will be a powerful telescope. If you were to use it on Earth, for example, you could stand 600 miles away from your best friends and still get a clear picture of their hair.
Gaia is one of more than a dozen telescopes being designed by scientists right now. The next generation of telescopes will reveal new parts of our universe that will seem surprising. The universe, with all its planets, stars and other strange objects, is a puzzle with pieces that we can see by using powerful telescopes.
（1）How many different angles can Gaia focus at each time?
A.2.
B.3.
C.4.
D.5.
（2）The map to be drawn by Gaia ______.
A.can show every building on Earth
B.can show you where your town is
C.will just show the stars around Earth
D.will show where the stars are in our home galaxy
（3）What's Paragraph 4 mainly about?
A.What Gaia will do in space.
B.When Gaia will start to work.
C.How powerful Gaia will be.
D.What Gaia will do to Earth.
（4）The underlined sentence in the last paragraph suggests that the next generation of telescopes _______.
A.seem very surprising to scientists
B.will not be put into use in a short time
C.will just look at new things in universe
D.will be more powerful than the old generations

【答案】
（1）A
（2）D
（3）C

【題目】When we smile, our system recognizes that there’s an absence of threat, and relaxes: It slows down our heart rate, and may temporarily reduce blood pressure, too, promoting overall heart health. Even forcing your face into a smile can reduce stress and relax your heart rate.

Smiling is a language that everyone understands regardless of age, race, culture, language, and nationality. We all know that when you smile at people, even strangers, they almost always smile back, spreading a kind of peace and goodwill. This contagious（有感染力的）smiling comes from a subconscious tendency to match other people’s emotions. It’s why people who spend time around children，who smile often, naturally smile more than people who keep mostly adults company.

People who are generous with smiles are considered more likeable and approachable than people who wear a deadpan（面無表情的）expression. Consider successful salesmen and politicians. Can you imagine how we’d react if they wore sour expressions? People who smile a lot are more likely to gain our trust — and earn better tips — than someone who provides the same service with an impassive face.

In a study, Major League Baseball players from 1952 who wore full-faced, genuine smiles on their baseball cards lived longer, around 79.9 years, compared to players who only partly smiled or didn’t smile at all, who lived 5 to 7 years less. Smiling can make us look younger, too: People who smile frequently seem to age more slowly, appearing around three years younger than their less smiley counterparts.

We now have evidence that we are hardwired to smile. While smiling used to be considered a learned behavior that babies acquired at around six weeks of age, more advanced ultrasound testing has shown that even babies who are bom blind can smile. Babies have been known to make breathing and sucking movements while still in the womb（子宮）, and these reactions are thought to prepare them for their life outside. Now smiling has joined the list. Say cheese!

【1】What can smiling do according to Paragraph 1?

A. Remove your life pressure.

B. Improve the condition of the heart.

C. Make your blood pressure steady.

D. Prevent you from being absent-minded.

【2】What should you do if you want to smile more according to the author?

A. Stay more with people smiling more.

B. Approach smart children.

C. Care more about others’ feelings.

D. Volunteer together with more strangers.

【3】What does the author want to show by mentioning salesmen and politicians?

A. A false smile may hurt people.

B. Smiles contribute to a career.

C. Generous people tend to smile more.

D. Work pressure stops people smiling.

【4】What does the author suggest in the last paragraph?

A. Babies smile within 2 months.

B. Blind babies learn to smile.

C. Smiling is a natural ability.

D. Breathing and sucking are similar to smiling.

【題目】When students and parents are asked to rate subjects according to their importance，the arts are unavoidably at the bottom of the list. Music is nice , people seem to say , but not important. Too often it is viewed as entertainment, but certainly not an education priority（優(yōu)先）.This view is shortsighted. In fact, music education is beneficial and important for all students

Music tells us who we are. Because music is an expression of the beings who create it, it reflects their thinking and values, as well as the social environment it came from. Rock music represents a lifestyle just as surely as does a Schubert song. The jazz influence that George Gershwin and other musicians introduced into their music is obviously American because it came from American musical traditions. Music expresses our character and values .It gives us identity as a society.

Music provides a kind of perception（視角）that cannot be acquired any other way. Science can explain how the sun rises and sets .The arts explore the emotive（情感的）meaning of the same phenomenon. We need every possible way to discover and respond to our world for one simple but powerful reason: No one way can get it all.

The arts are forms of thought as powerful in what they communicate as mathematical and scientific symbols. They are ways we human beings “talk” to each other. They are the language of civilization through which we express our fears, our curiosities our hungers, our discoveries, our hopes .The arts are ways we give form to our ideas and imagination so that they can be shared with others. When we do not give children access to an important way of expressing themselves such as music, we take away from them the meanings that music expresses.

So music education is far more necessary than people seem to realize.

【1】According to paragraph 1, students_______.

A. regard music as a way of entertainment

B. disagree with their parents on education

C. view music as an overlooked subject

D. prefer the arts to science

【2】In Paragraph 2, the author uses jazz as an example to.

A. compare it with rock music

B. show music identifies a society

C. introduce American musical traditions

D. prove music influences people’s lifestyles

【3】According to the passage , the arts and science.

A. approach the world from different angles

B. explore different phenomena of the world

C. express people’s feeling in different ways

D. explain what it means to be human differently

【4】What is the main idea of the passage?

A. Music education deserves more attention.

B. Music should be of top education priority.

C. Music is an effective communication tool.

D. Music education makes students more imaginative.

【題目】While being lost in the woods can be a frightening experience, surviving alone in the wild is generally a matter of common sense, patience, and wisely using the gifts that nature provides.【1】.

Do your research first. Don't just trek off into the wilderness; get a solid understanding of your surroundings first. Studying a map of the area where you're going -- and making sure to bring it with you -- will increase your chances of not getting lost tremendously. Educate yourself about the flora and fauna of the area you are exploring. 【2】.

【3】.A cell phone with a spare battery or a portable CB radio can be your best, quickest means of rescue if you are truly lost or injured. A cell signal may only be obtainable only from a hill or tree, but is better than nothing. Serious hikers may even consider investing in a personal locator beacon such as the SPOT Messenger for extended, precarious, or very remote, treks.

Don't panic if you’re lost.Panic is more dangerous than almost anything else, because it interferes with the operation of your single best, most useful and versatile survival tool: your mind. The moment you realize that you are lost, before you do anything else, stop.【4】.Before you act, follow the idea of STOP: S = sit down T = think　O = observe your surroundings P = prepare for survival by gathering materials.

Signal your location.Make noise by whistling, shouting, singing, or banging rocks together. 【5】 . If you're in a mountain meadow, make three piles of dark leaves or branches in a triangle. In sandy areas, make a large triangle in the sand. Three of anything in the wilderness is a standard distress signal.

A. Bring a means of communication.

B. If you can, mark your location in such a way that it's visible from the air.

C. Knowledge of the local plants and animals can save your life

D. If you want to know how to survive in the woods, just follow these steps.
