NASA said its Kepler spacecraft has spotted ''Earth's bigger, older cousin'': the first nearly Earth-size planet to be found in the habitable zone of a star similar to our own.
Though NASA can’t say for sure whether the planet is rocky like ours or has water and air, it's the closest match yet found.
The planet, Kepler-452b, is about 60% bigger than Earth, NASA says, and is located in its star's habitable zone, where life-sustaining liquid water is possible on the surface of a planet.
A visitor there would experience gravity about twice that of Earth's, and scientists say the possibility of it having a rocky surface are ''better than ever''. While it's a bit farther from its star than Earth is from the sun, its star is brighter, so the planet receives about the same amount of energy from its star as Earth does from the sun.
Kepler researcher Jeff Jenkins said, ''The planet almost certainly has an atmosphere, although scientists can't say what it's made of. But if the assumptions are correct, kepler-452b's atmosphere may be thicker than Earth's. ''
It takes 385 days for the planet to orbit its star. ''Because it has spent so long orbiting in this zone—6 billion years—it's had plenty of time to brew life,'' Jenkins said.
''That's an opportunity for life to arise, if all the necessary ingredients and conditions for life exist on this planet, '' he said in a statement.
Kepler-452b is too far away for humans to visit. But the discovery of this new Earth-like planet can tell us a lot about what’s possible for the future of space travel. ''The next step in the process is to do follow-up missions to find planets similar to kepler-452b, but much closer to Earth, '' said Peter Coughlin, a Kepler research scientist. ''We could do a lot more research into those planets, and even start to think about visiting one day. ''
1.The researchers are sure that Kepler-452b ________．
A.is larger than Earth B.has an atmosphere
C.has air and water D.has many rocks
2.What is the similarity between Kepler-452b and the Earth?
A.They are both located in the sun's habitable zone．
B.Their distances from the sun are almost the same．
C.Their atmospheres are made of the same compositions．
D.They get almost the same amount of energy from their stars.．
3.The underlined word ''brew'' in paragraph 6 most probably means ________.
A.improve B.endanger
C.produce D.protect
4.What should be the best title for the text?
A.Kepler-452b Is Compared to the Earth.
B.NASA Discovers a New Earth-Like Planet.
C.A Spacecraft Was Launched to Find Super-Earth.
D.A New Planet With Life Is Discovered.

NASA has a new job listing, and it’s no joke. The US space agency (机构) is looking for a “joker” to join their planned mission (任务) to Mars.
A mission to Mars is no laughing matter. On average, the red planet is 140 million miles (225 million kilometers) away from Earth. A trip there would take around eight months in a small spacecraft. And Mars has a communications delay (延迟) of 20 minutes. This means that astronauts will have to wait 20 minutes for a reply, when an emergency happens.
“When you’re living with others in a confined space for a long period of time, such as on a mission to Mars, problems are likely to occur,” Jeffrey Johnson, a scientist at the University of Florida, told The Guardian.
This is probably why NASA wants an astronaut with a sense of humor. “These are people that have the ability to pull everyone together,” Johnson said.
In stressful situations, perhaps humor is a way to know we aren’t alone. By laughing together, we share our stress. Then we can focus on our jobs instead of just worrying.
There are other examples of team “clowns”. One example is the journey to the South Pole (南极) led by Norwegian explorer Roald Amundsen. It was a difficult journey, full of danger. Adolf Lindstrom, a cook at Amundsen’s team, was a “clown”. He made people laugh through the whole journey. Amundsen later wrote that Lindstrom was the most valuable member of the team.
But if you’re hoping that your favorite TV comedian (喜剧演员) will fly to Mars, that probably won’t happen.
“Being funny won’t be enough to land somebody the job,” Johnson said. “They also need to be an excellent scientist and engineer.”
Besides, they must be in top physical condition.
1.What is NASA’s new job listing?
A.A funny engineer. B.A talented clown.
C.A good cook. D.A popular comedian.
2.What does “a confined space” in Paragraph 3 refer to?
A.a crowded space B.an empty space
C.an open space D.a small space
3.How does the author think humor can help astronauts?
A.It can stop them from feeling worried.
B.It can encourage teamwork on a mission.
C.It can help them feel less homesick.
D.It can help them know themselves better.
4.What could be the best title of the passage?
A.A New Job Listing of NASA
B.Humorous Astronauts in NASA
C.Keeping the Spirits Up
D.A mission to Mars

Terrafugia Company has said that its flying car, named Transition, has successfully finished a 37- second test flight
On March 5, 2009, at Plattsburgh International Airport in New York. It was piloted by Phil Meteer, the company's chief pilot.
Transition is a two-seat airplane that can take off and land at airports as well as drive on roads.
The company said that the flying car can travel at speeds up to 115 mph for 450 miles in the air, drive at highway speeds on the ground, and fold up(折叠) to fit in a garage (车库) 81 inches wide, and 80 inches high.
This could be used in hospitals to transport patients so as to avoid road traffic. It may start running on wheels, and when it gets to traffic lights it can fly overhead the lights and keeps its way forward. So it’s good news to avoid traffic problem and the traffic accidents.
But some people say this is a going airplane rather than a flying car, at least on the appearance. Anyway, we are happy for scientific-technical progress, what a fantastical world in the near future!
1. This kind of new machine is made by ______.
A．Phil Meteer
B．Terrafugia Company
C．Plattsburgh International Airport
D．both A and B
2. ___ people can sit in Transition.
A．3 B．5 C．4 D．2
3. Transition can travel ____ miles every hour in the air .
A．115 B．120 C．450 D．480

A．It can be folded up.
B．It can both run on the ground and fly in the sky.
C．It is used in hospital now.
D．It looks like a plane .

It’s often said that the rise of social media has revolutionized (彻底改变) communication. With smartphones and social networking apps, we can write to our family and friends whenever we like. But while social media has brought us convenience, it also has its problems, such as misunderstandings in communication.
Quite often, people misunderstand what’s written on social media. According to a story published on The Conversation on March 8, sarcasm (讽刺), in particular, can be very difficult to notice in a written message.
Sarcasm is a kind of irony (反语): It’s when we say something, but really mean the opposite. For example, a message from a friend the day before a math exam that says “I’m so looking forward to tomorrow!” is obviously sarcasm.
Sarcasm before the rise of social media and mobile phones was mostly used in speech and face to face. That made sarcasm easier, because you could accompany your words with a facial gesture and a tone (语气) of voice that would help others get your message. You had a good chance of being understood and receiving a laugh or an understanding glance.
And yet when we text or write something online, a lot of that information goes missing. “There are no facial hints, no tones or maybe even a delayed response if a person can’t text you back immediately,” wrote The Conversation. “And if you don’t know the person all that well, there goes your last possible hint: history.”
To help avoid misunderstandings, people who use platforms such as Twitter often include the hashtag ﹟sarcasm – although this is like having to explain a joke when people don’t laugh at it, which destroys the point of sarcasm in the first place.
And it isn’t only sarcasm that can get lost in electronic communications. It’s also hard to notice things such as indifference (冷漠).
“One of the problems with digital communication, when it relies purely on text, is that this sucks (抽离) the empathy (情感共鸣) out of the communication. So it can lead to miscommunication,” linguist Vyv Evans, author of The Emoji Code, told USA Today. “This is where emojis come into their own. They put the body language back, so people can better read emotional intent (目的).”
However, even though there are hundreds of different emojis(表情符号) to choose from, there’s still no replacement for good old-fashioned face-to-face communication.
1.What does the underlined sentence in the third paragraph mean according to the context?
A.They can’t wait to take the exam.
B.They are well-prepared for the exam.
C.They’re not looking forward to taking the exam at all.
D.The exam might be too difficult for them.
2.What might lead to the words we write online being misunderstood, according to the Conversation?
A.The use of new internet words and phrases.
B.The complicated relationship between people.
C.The absence of facial expressions and tones.
D.Responding to other people too quickly.
3.What does Vyv Evans think is a possible way to avoid miscommunication online?
A.Using emojis, as they can display body language.
B.Expressing fewer personal feelings.
C.Sending voice messages instead of text messages.
D.Using a hashtag before making jokes.
4.What is the article mainly about?
A.The convenience of online communication.
B.Some misunderstandings that come with digital communication.
C.A good replacement for face-to-face communication.
D.Some reasons for the popularity of emojis.

Forgiveness
To forgive is a virtue, but no one has ever said it is easy. When someone has deeply hurt you, it can be extremely difficult to let go of your hate. However, forgiveness is possible, and it can be surprisingly beneficial to your physical and mental health. People who forgive show less sadness, anger and stress and more hopefulness, according to a recent research.
1. Try the following steps：
Calm yourself. 2. You can take a couple of breaths and think of something that gives you pleasure: a beautiful scene in nature, or someone you love.
Don’t wait for an apology. Many times the person who hurt you does not intend to apologize. They may have wanted to hurt you or they just don’t see things the same way. 3. Keep in mind that forgiveness does not necessarily mean becoming friends again with the person who upset you.
Take the control away from your offender (冒犯者). Rethinking about your hurt gives power to the person who caused you pain. Instead of focusing on your wounded feelings, learn to look for the love, beauty and kindness around you.
4. If you understand your offender, you may realize that he or she was acting out of unawareness, fear, and even love. You may want to write a letter to yourself from your offender’s point of view.
Don’t forget to forgive yourself. 5. But it can rob you of your selfconfidence if you don’t do it.
A．Why should you forgive?
B．How should you start to forgive?
C．Recognize the benefits of forgiveness.
D．Try to see things from your offender’s angle.
E．For some people, forgiving themselves is the biggest challenge.
F．To make your anger die away, try a simple stressmanagement technique.
G．If you wait for people to apologize, you could be waiting an awfully long time.
