On a clear night, the sky is a wonderful thing. Is there life out there somewhere? Is there another place like Earth where life might exist? If so, where is it? And how far away is it?

Recently, the Kepler spacecraft found “22b”, a planet about six hundred light years away. It is the first planet in a “habitable zone” outside the solar system. That means the planet orbits(环绕) a star like our sun, but it is not too close to it, nor too far away. Because of this position, Kepler-22b might have water, one of the main things needed for life. The newly-discovered planet is about two and a half times larger than the Earth. It is closer to its star than we are to the Sun, but 22b’s sun is smaller than ours, and doesn?t produce as much heat. Scientific instruments show the new planet could be made of gases, rocks or some kinds of liquids.

The Kepler spacecraft was named in honor of Johannes Kepler, the seventeenth century German astronomer. It was designed to examine a small part of the Milky Way galaxy(星系)and search for places like the Earth. It was made to inspect over 150,000 stars and measure how bright they are. It looks to see if a star’s brightness gets less over a short time.

If a planet passes between Kepler and the star, it blocks out part of the light. That is what suggested to scientists that there is at least one planet orbiting the star. The instruments on Kepler show the new planet as a small, black dot moving across its sun. An important part of the Kepler experiment is on the Earth. After the spacecraft gathers information, scientists use the telescopes on the ground.

Scientists have found over 2,300 new planets since Kepler was launched. Most are much larger, but it is the new planet’s distance from its star that is important. For life to possibly exist there, the planet’s temperature must not be too hot or too cold.

1.What can we learn about Kepler-22b?

A. Water must have existed on it.

B. It takes humans about 600 years to get there.

C. It is made of gases, rocks and plenty of liquids.

D. It is the first planet in outer space where life may survive

2.The Kepler spacecraft was sent into space to

A. show honor to Johannes Kepler

B. observe the changes of a star’s brightness

C. look for Earth-like planets in the Milky Way galaxy

D. measure the brightest star among 150.000 stars

3.In Paragraph 4 the author mainly tells us

A. how the Kepler system works

B. if the Kepler system sees a new planet

C. how the Kepler system shows a new planet

D. why an important part of the Kepler system remains on the Earth

4.What can we infer from the passage?

A. Life may exist on the new planet in another form.

B. It is colder on the new planet because its sun is smaller.

C. Life can’t exist on planets which are much larger than the Earth.

D. The new planet’s distance from its star decides on the possibility of life existence.

B Edinburgh is the capital city of Scotland, and has long been a favorite destination of tourists from all over the world, as well as an important cultural and political center.

With its museums, shops, wonderful historic castle, and many pubs and restaurants, there are many things for visitors to enjoy all year round.And of course, as it is in Scotland, there are a wide range of whiskies to try!

However, there is more to Edinburgh than historic monuments and tourism.Each year, the Edinburgh Festival takes place in the city.In late summer, for three weeks, the festival presents classical music, theater, opera and dance at six major theaters and concert halls—and several smaller ones—throughout the city.Whatever your cultural tastes, you are sure to find something to enjoy.、

Local talent is always represented at the Edinburgh Festival giving Scottish composers and playwrights the opportunity to showcase their work and gain recognition from a wider audience.

In addition, orchestras (管弦乐队) and theater companies come from all over the world to perform at the prestigious (有名望的) festival.Last year saw the arrival of orchestras from the United States and Germany.

The festival has now become an important part of Scotland’s economy as well as its culture.Last year’s festival generated over £130 million expenditure in Edinburgh alone, and across Scotland nearly 2,900 jobs exist as a direct result of the festival.

The festival is so popular that it has become, in some ways, a victim of its own success.The huge interest in performing there led to the setting up of a rival (竞争的) festival, the Edinburgh Fringe Festival.Fortunately, demand for live entertainment during the summer is so great that both festivals continue to thrive (兴旺).

The Fringe tends to feature mostly comedy and experimental works.Yet it can lead to great things ---- many famous and successful comedians and artists, such as Rowan Atkinson, better known as TV’s Mr.Bean, started their careers in small venues at the Fringe.
