【题目】American researchers have discovered that human brains and sleep patterns are confused by devices(装置) that give out bright lights. Electronics, such as laptops, mislead our minds into thinking that it is still daytime, preventing sleep and increasing the risk of insomnia.

Sleep experts say human's natural body clock begins to rest and relax from the day between 9 and 10 pm but the use of computers confuses it.

A person's brain biologically becomes awake when the sun is out because bright light after dark causes the brain to stop producing the hormone (荷尔蒙) called melatonin that makes us sleepy.

Researchers say blue light from devices such as iPads, which is expected to become a popular reading tool when it comes out later this month, is particularly disruptive (干扰的)during the night when the brain thinks it should be dark.

Experts say a good book is a far better way of resting the brain and ensuring a good night's sleep because the bedside lamp(灯) light doesn't affect the brain as it does not look straight into a person's eyes.

“Potentially, yes, if you're using an iPad or a laptop close to bedtime... that light can be stimulating (刺激) to the brain to make it more awake and delay your ability to sleep,” Phyllis Zee, a professor at Northwestern University and director of the school's Centre for Sleep & Circadian Biology, told CNN.

“And I think more importantly, it could also be enough to affect your circadian (昼夜节律的) rhythm. This is the clock in your brain that determines when you sleep and when you wake up. ”

Alon Avidan, associate director of the Sleep Disorders Center at the University of California Los Angeles, added, “I wish people would just take a boring book — an oldfashioned book — and read by a lamp.”

【1The underlined word “insomnia” in the first paragraph probably means “________”.

A.being unable to eat properly

B.brain injury

C.being unable to fall sleep

D.lack of energy

【2】Melatonin is the hormone that ________.

A.makes us sleepy

B.helps us relaxed

C.prevents us from waking up

D.makes us excited

【3】The bedside lamp light doesn't affect the brain because ________.

A.it doesn't give out blue light

B.it's not as bright as your laptop

C.it doesn't enter your eyes directly

D.it is adjustable

【4】We can conclude from the passage that ________.

A.one who uses his laptop often before bedtime can have his body clock disturbed

B.using a laptop before bedtime is more harmful than using an iPad

C.we'd better not do anything before going to bed

D.the best time to go to bed is before 9 pm

【题目】改编】A few years ago, I was on a plane with my friend, waiting for it to take off. The pilot’s voice was heard throughout the plane: “Sorry for the delay, ladies and gentlemen. Our engines don’t work. We are going to jump-start them. Once we get them going, we’ll get up in the air and see what happens.”

That was all he said. “See what happens?” Shouldn’t we have had a better plan than that? At that point. I could only laugh nervously. One woman started crying, “Oh no! We are going to crash!’’ There were sighs of hopelessness and anxiety, and we hadn’t even taken off yet.

The pilot even seemed unhappy. He told us our one engine was working double time, and his plan was to get up in the air and see what happens! Then we did. We got up in the air, and what happened? Nothing. We arrived in Norfolk, and no sooner had the wheels touched down than applause burst out as everyone on the airplane breathed a sigh of relief.

While I do prefer planning better than “see what happens” when it comes to flying, it really isn’t such a bad idea for life.All too often, people stop trying to achieve their goals just because they don’t have a guaranteed result. But success will never be guaranteed. The best thing that you can do is just get up in the air, and see what happens. If your effort is to build a business then get up in the air and see what happens! Don’t give yourself all the reasons why you can’t. Do not wait until you have everything you need. You never will!

If your goal is to start a friendship, say “Hello”, get up in the air and see what happens! The results could be very rewarding.

If your goal is to learn a new skill, get up in the air and see what happens! It might not be as difficult as your think. It could be fun!

When traveling, i hope that my pilot has a more detailed plan than “we will see what happens” . But in life, it is not a bad strategy at all.

【题目】Anna Riviere was one of the most admired of 19th-century English sopranos(女高音). She was also one of the most adventuresome.

She was born in London on January 9th, 1810. She entered the Royal Academy of Music at the age of 14. Seven years later, just after her first show, Anna married Sir Henry Bishop, who was 24 years her senior. Her reputation as a singer grew rapidly, based largely on her tours with Sir Henry and harpist Nicholas Bochsa. After a tour of Dublin, Edinburgh, and London, Anna Bishop deserted her husband and three children and ran away with Bochsa.

From then on, Madame Bishop—as she continued to be known—traveled and sang as if her life depended on it. Between 1839 and 1843 she traveled to every major town in Europe, where she sang in 260 concerts. In the course of two years in Naples, she performed in 20 operas. In 1855 she and Bochsa sailed for Sydney, Australia. He died there the following year, and Anna went on to tour South America before returning to New York, where she married a diamond merchant.

Then she began what proved her most dangerous adventure. After another American tour in 1866, she and her husband set sail across the Pacific. They were shipwrecked on a small coral reef, and for more than a month they drifted in a small boat before they finally reaching Guam. She had lost her music, her wardrobe, and her jewelry, but Madame Bishop was not to be stopped. She went on to Manila and began a concert tour that led to Hong Kong, Singapore, and India before she went back to England. After another two-year world tour she returned eventually to New York, where she gave her last public performance in 1883—at age 73.

Meanwhile the husband she left behind, Sir Henry, had become famous for writing the music to lyrics that might eventually have been meaningful to Anna Bishop—“Home, Sweet Home.”
