Set your clocks for 4:32 pm(eastern time)on May 27th, 2020. If everything goes as planned, a rocket will launch from Kennedy Space Center in Cape Canaveral, Florida.
1. So what’s the big deal? The big deal is collection of firsts set to blast off on the 27th of May. The first humans carried aboard a rocket developed by a private company. The first humans aboard a reusable rocket.
Ever since the opening days of the space age, NASA has designed, built, and flown its very own rockets, and capsules. 2. The privately-held company Space X will be providing the big rocket boost(加湿器)needed to get NASA’s astronauts to the space, aboard a Falcon 9 rocket topped with a Dragon crew capsule.
3. It is trying to make access to space cheaper, chiefly through the use of reusable rockets- once the payload is delivered into orbit, bring the rocket back down the Earth and polish it up for another ride.
In the meantime, NASA has spent the past decade in a highly bureaucratic version of hell. After the sad end of the space shuttle program in 2011, the American space agency was forced to rent seats on Russian made and Russian launched Soyuz rockets to get astronauts up to the International Space Station.
4. And now, if everything goes as planned on May 27th, we will make human access to space cheaper, more reliable, and absolutely easier. 5. Space tourism? Moon bases? I would say that the sky is limit, but the sky is just the start.
A.But this time, it’s different.
B.Rockets go off all the time from the Earth.
C.This made for great wounded national pride.
D.Most of the astronauts haven’t made it up into space.
E.Space X has spent the past decades working tirelessly.
F.NASA has been developing a new space launch system.
G.It’s impossible to say what kind of revolutions that might lead to.

高三英语短对话中等难度题查看答案及解析
People may set an alarm on the phone or clock that sounds like this: beep beep beep. That hard, unpleasant sound may be making it harder to shake off the sleepy feeling in the morning known as grogginess. So, is there a better way to wake up? A recent study says yes. The answer is music.
The study, carried out by researchers in Australia, involved 50 people. The researchers found that people who wake up to musical alarms reported feeling more awake and alert. Stuart McFarlane, a lead writer of the study stated, "We are very surprised by these findings as one might expect a harsh beeping sound to be more successful," at waking up a person.
Sleep inertia is another term for grogginess. It means a person has a heavy feeling when waking up, and has trouble getting moving again after sleeping. McFarlane said people need to better understand sleep inertia's harmful effects on human performance later in the day.
Not everyone will experience the full effect. But for those who do, "care should be taken" when performing duties that require a top performance within this period, he said. This includes "dangerous tasks like driving or riding our bikes" shortly after waking up. The same is true for people who work in dangerous situations shortly after they wake, including firefighters and pilots.
So, what makes musical alarms better for waking up? The researchers think the music may be more successful in reducing sleep inertia because it has several tones, compared to the single tone of a "beeping" alarm. McFarlane said that the changes over time between the music tones may help increase a person's attention when waking from sleep.
And is there a kind of music that is best to wake up to? There may be, McFarlane said. "We could suggest alarm sounds that are tune full and easy to hum or sing along with. The current sounds I have been using include 'Close to me' by the Cure and 'Borderline' by Madonna."
No matter how you wake up, experts say, the amount of sleep you get also matters — a lot.
1.Which of the following might be the best title for the text?
A.What is grogginess? B.Why are musical alarms better?
C.Which music is the best? D.How can we overcome grogginess?
2.Which of the following statements is TRUE according to the passage?
A.Sleep inertia is another cause for grogginess.
B.How long a person sleeps is of great importance.
C.The 'beeping' alarm is not effective mainly because of its noisy tone.
D.It is dangerous for everyone to drive or ride bicycles shortly after waking up.
3.The paragraph following this passage is likely to focus on .
A.examples of good musical alarms
B.more findings of the application of music
C.explanations about why music is more helpful
D.suggestions on how to sleep well and feel fresh each morning
4.In which section of a magazine may you find the passage?
A.Health. B.Fiction.
C.Technology. D.Entertainment

On Sunday, March 11, most Americans will set their clocks forward an hour, as daylight saving time (sometimes wrongly called daylight savings time) begins and most of the United States can enjoy an extra hour of daylight. The spring and fall clock changes continue a long tradition started by Benjamin Franklin to conserve energy.
Benjamin Franklin lakes the honor (or the blame, depending on your view of the lime changes) for coming up with the idea to reset clocks in the summer months as a way to conserve energy. By moving clocks forward, people could take advantage of the extra evening daylight rather than wasting energy on lighting. At the time, Franklin was ambassador to Paris and so wrote a letter to the Journal of Paris in 1784, rejoicing over his “discovery” that the sun provides light as soon as it rises.
Even so, DST (Daylight Saving Time) didn’t officially begin until more than a century later. Germany established DST in May 1916 as a way to conserve fuel during World War I. The rest of Europe came onboard shortly thereafter. And in 1918, the United States adopted DST.
Though President Woodrow Wilson wanted to keep daylight saving time after WWI ended, the country was mostly rural at the time and farmers objected, partly because it would mean they lost an hour of morning light. And so daylight saving time was abolished until at the start of WWII, on Feb. 9, 1942, President Franklin Roosevelt re-established daylight saving time year- round, calling it “War Time.”
After the war, a free-for-all system in which U.S. states and towns were given the choice of whether or not to observe DST led to disorder. And in 1966, to avoid such “Wild West” confusion, Congress passed the Uniform Time Act. That federal law meant that any state observing DST — and they didn’t have to jump on the DST system — had to follow a uniform timing system throughout the state in which daylight saving time would begin on the first Sunday of April and end on the last Sunday of October.
Then, in 2007, the Energy Policy Act of 2005 went into effect, expanding the length of daylight saving lime to the present timing.
1.What is the passage mainly about?
A. What is Daylight Saving Time?
B. How did Daylight Saving Time start?
C. Who proposed Daylight Saving Time?
D. Why Daylight Saving Time is adopted?
2.It can be inferred that .
A. DST was adopted in the US mainly to preserve fuel
B. DST lasted for 24 years in the US before being canceled
C. it is still free for the states in the US to adopt the DST or not
D. farmers in the US rejected DST for losing an hour of evening light
3.What is the meaning of the underlined expression “rejoicing over” in paragraph 2?
A. Taking pride in. B. Taking interest in.
C. Feeling regret for. D. Feeling surprised about.
4.Which country adopted DST earliest, according to the passage?
A. France. B. Germany.
C. England. D. The United States.

How do you wake up in the morning? Imagine you set an alarm on your phone or clock that goes off like this: beep beep beep. 1. The state is known as grogginess (东倒西歪). So, is there a better way to wake up? A recent study says yes. The answer is music. Researchers say alarms that have a melody can help people feel fresher in the morning.
Sleep inertia (睡后迟钝) is another term for grogginess. 2. Someone even has trouble getting moving again after sleeping. Stuart McFarlane was a lead writer of the study. He said people need to better understand sleep inertia’s harmful effects on human performance later in the day.

Down on the beach of Dover, 56-year-old Channel swimmer Jackie Cobell bravely set off for Calais. The time was 6:40 am. 28 hours and 44 minutes later the exhausted, successful mother from Kent crawled (爬行) to the shore and walked proudly into the record books. After five years in training, Mrs Cobell became the slowest person to cross the Channel under her own steam. The previous record for the slowest crossing, set by Henry Sullivan at 26 hours and 50 minutes, has stood for 87 years before Mrs Cobell started at Dover Saturday morning.
She had struggled through changing tides that swept her first one way, then the other. It turned the 21-mile crossing into a 65-mile one. She declared, “Time and tide wait for no man—and they certainly didn’t wait for me. I was fully expecting it to get dark before I got to Calais but I never imagined I’d also see the dawn again. But I wasn’t going to give up.”
Her feat(壮举) raised more than $2,000 in charity sponsorship for research into Huntingdon’s disease, a sum that was continuing to grow as news of her achievement spread. That was why she did it. “I don’t really know myself,” she said. “ I just kept thinking of all the people I’d be letting down if I stopped.”
Mrs Cobell took to the water so well at school. But after bringing up two daughters, she started to gain weight. Five years ago she took up swimming again and decided to prepare for the Channel challenge to lose weight. She became much fitter. Then came the big swim. “I practiced on Windermere lake,” she said. “it’s about half the distance of the Channel so I just doubled it, added some extra time, and worked out I could probably get to Calais in about 16 hours.”
Her husband David, trainer, official observer and friend sailed alongside her on a boat. She said, “I sang to keep myself going. When they told me I was a record breaker I thought they were just having a joke—until I realized it was the record for the slowest crossing. But maybe next time I might be a bit quicker.”
1.According to Paragraph 1, Mrs Cobell_____________.
A. started to learn swimming five years ago
B. arrived at Calais on late Sunday morning
C. wanted to break the record for the slowest crossing
D. was too exhausted to move after crossing the Channel
2.Why did Mrs Cobell spend so much time crossing the Channel?
A. Because the tides changed her direction.
B. Because she was not in good condition.
C. Because she wasn’t good at swimming.
D. Because the winds kept her from swimming fast.
3.Mrs Cobell crossed the Channel for the main purpose of____________.
A. taking a risk
B. losing more weight
C. raising money for charity
D. becoming famous worldwide
4. How did Mrs Cobell feel about the record she set?
A. Dissatisfied B. Excited C. Annoyed D. Proud

Editor Henry Slocum，
I read your May 10th article in the local newspaper Honesdale Times about electronic books，or e-books，with great interest．You made several good points about the disadvantages of e-books．You may have overlooked，however，some of the ways in which they are superior to traditional books．Yes，e-books are expensive，but they are also convenient．In addition，due to their environment-friendly nature, e-books have the potential to change our planet for the better．
E-books, for anyone who is unfamiliar with the term，are about the same size and shape as regular books．They have a large screen in the middle，however．This screen shows the reader a page of text that has been downloaded from a computer．Once the reader has finished reading the page on the e-book screen．he or she scrolls down to see a new page．The process continues until the entire book has been read．
As you pointed out．Mr．Slocum，it's great to lie on a warm，sandy beach with a book．You can do that just as easily with an e-book as you can with a traditional paper book．In fact，because e-books are so light, you can carry them anywhere．Say，for example，that you like to read on the bus．Which would you rather carry with you-a heavy 800-page novel，or an e-book that weighs only a few ounces?
Another important advantage is offered by e-books as well．They are more environmentfriendly than traditional books．At present，thousands of trees are cut down each year to meet the publishing industry’s demand for paper．Books that don’t sell are eventually returned to the Dublisher and destroyed．This terrible waste could be avoided if everyone used e-books，which require no paper．
Sincerely，
David Eng
