Blind people are better at locating sounds than people who can see, a new study says, without the benefits of vision the ears seem to work much better
Previous studies have shown that blind people are better than others at reaching out and touching the sources of sounds that are close by. Researchers from the University of Montreal wanted to see if blind people were also better at locating sounds that are far away.
Twenty-three blind people participated in the study. All had been sightless for at least 20 years. Fourteen of them had lost their vision before age 11. The rest went blind after age 16. The experiment also included 10 people who could see but were wearing blind-folds.
In one task, volunteers had to pick the direction of a sound coming from about 3 metres away. When the sound was in front of them or slightly off center in front, both groups performed equally well.
When sounds came from the side or the back, however, the blind group performed much better than the blindfolded group. The participants（参与者）who had been blind since childhood did slightly better than those who lost their sight later.
“Recognizing（认识）the locations of distant sounds can be a matter of life-or-death for blind people,” say the researchers. Crossing the street, for instance, is much harder when you can’t see the cars coming.
Still, the researchers were surprised by how well the blind participants did, especially those who went blind after age 16. In another experiment, the scientists also found that parts of the brain that normally deal with visual（视觉的）information became active in locating sound in the people who were blind by age 11. These brain parts didn’t show sound-location activity in the other group of blind people or in the sighted people. The scientists now want to learn more about the working of brains of “late-onset” （迟发性的）blind people.

B. All the volunteers in the experiment are sightless.
C. All the participants did equally well when picking sounds from whatever direction.

Where did that number come from?
Eleven and Twelve
The reason behind the change in number naming is that eleven comes from the German term ainlif, which translates to “one left”. Twelve follows the same rule. It comes from twalif—“two left”. Why teen is used instead of lif for 13 through 19? There is something sadly lost in history.
911 for US Emergency (急救) Calls
Early phones didn’t use phone numbers—the operator had to connect your call by hand—and this led to the need for an emergency code (信号). But later phone numbers became popular, that changed. In 1967, 911 was chosen as the nationwide emergency call because it was easy to remember and could be quickly dialed (拨) on the phone.
26.2 Miles in a Marathon (马拉松)
The story began with an ancient Greek soldier carrying message from a battlefield (战场) in Marathon to Athens. The modern marathon was born as a flagship event in the first Olympic Games, in 1896, with a distance (距离) of about 25 miles (40 km), as long as the distance from Marathon to Athens. But race organizers for the 1908 Olympic Games in London wanted to add something special. The race began at Windsor Castle and ended at White City Stadium, with runners finishing only after passing the royal (皇室的) box. The distance was 26.2 miles (42.1 km). And since 1924 this distance has been kept in marathon.
28 Days in February
Before using the Gregorian calendar that we use today, one of the first Roman calendars had only 304 days and ten months (March through December), with six months of 30 days and four of 31 days. The second king of Rome improved the old calendar. He added 50 days for January and February. To make the new months longer, he took one day from each of the 30-day months, making 56 days to divide between January and February (or 28 days each). Later January was given one more day to add up to 355 days a year, but February still had 28 days. That’s how it became the shortest month and it stayed that way ever since.
1.Which language do eleven and twelve come from?
A. English. B. German. C. French. D. Russian.
2.When was the number 911 chosen for US emergency calls?
A. In 1896. B. In 1908. C. In 1924. D. In 1967.
3. The marathon distance was made longer at London Olympic Games because ______.
A. the British was a little weak in maths
B. the British didn’t like the Greek story
C. the British loved the royal family very much
D. the British wanted to make the race different
4. How many days were there in each month after the king improved the old calendar?
A. 28, 29 or 31. B. 28, 30 or 31.
C. 28, 29 or 30. D. 29, 30 or 31.

How do you remember the way to your house? Where do dreams come from? It is your brain(大脑) that does these things. A British scientist showed that “sleep can improve one’s memory.” It’s not a dream for students to study when they sleep. In fact, your brains is working day and night. If you learn words before bed, a certain part of the brain may help you to remember the words while you sleep. What’s more, another scientist in the USA found that there was a “talent button(天才按钮)” in the human brain. It might make a person more talented.
There are more interesting things about the brain. Your brain uses less energy than a fridge light. Just two bananas can give the brain enough energy to work for a whole day. According to some scientists, yawning(打哈欠) keeps our brains “cool”, which makes us think quicker.
Here are some pieces of advice to keep a good brain:
l Eat healthy food.
l Get a lot of playtime or exercise.
l Don’t drink or smoke.
l Use your brain a lot.
1. A British scientist found out that ________ could improve our memories.
A. drink B. dreams C. sleep D. bananas
2. According to the passage, if we want to have a good brain, we should ________.
A. use our brains more B. sleep fewer hours
