An alcohol breath test (ABT) is often used by the police to find out whether a person is drunk while driving. In the United States, the legal blood alcohol limit is 0.08% for people aged 21 years or older, while people under 21 are not allowed to drive a car with any level of alcohol in their body. A “positive” test result, a result over the legal limit, allows the police to arrest the driver. However, many people who tested positive on the test have claimed that they only drank a “non-alcoholic” energy drink. Can one of these energy drinks really cause someone to test positive on an ABT? Researchers in Missouri set up an experiment to find out.
First, the amount of alcohol in 27 different popular energy drinks was measured. All but one had an alcohol level greater than 0.005%. In nine of the 27 drinks, the alcohol level was at least 0.096%.The scientists then investigated the possibility that these small levels of alcohol could be discovered by an ABT. They asked test subjects to drink a full can or bottle of an energy drink and then gave each subject an ABT one minute and 15 minutes after the drink was finished.
For 11 of the 27energy drinks, the ABT did find the presence of alcohol if the test was given within one minute after the drink was taken. However, alcohol could not be discovered for any of the drinks if the test was given 15 minutes after the drink was consumed. This shows that when the test is taken plays an important role in the test result. The sooner the test is conducted after the consumption of these drinks, the more likely a positive alcohol reading will be obtained.What is the legal alcohol level for a 20-year-old driver in the US?

Work Your Mind
Here’s something to think about the next time you ask your teacher for help: struggling with schoolwork on your own can help you learn. According to a recent study, the more you struggle while you are learning new information, the better you can remember it later.
This theory might surprise you. When teachers are presenting new information, they often give students lots of help. But a new study shows this may not be the best way to support learning. “Don't be too quick to get help when learning something new,” education expert Manu Kapur told TFK. “Try to work on it yourself even if it means trying different ways.”
Kapur came up with the idea that struggling can lead to better learning. Then he tested it out on students in Singapore. He separated students into two groups. In the first group, students were asked to solve math problems with the teacher’s help. In the second group, students were asked to solve the same problems by helping one another, instead of getting help from the teacher.
With the teacher’s help, students in the first group were able to find the correct answers. Students in the second group did not solve the problems correctly. But they did come up with a lot of good ideas. The students were then tested on what they had learned. The group without any help from a teacher scored much higher than the group who had help. Kapur said working to find the answers helped students understand the process, not just the solution.
Kapur’s advice for kids is to put a lot of effort into learning something new rather than going to your teacher for help. “Simply doing a little work or nothing at all won’t work,” says Kapur. “The struggle needs to be a genuine attempt to figure out or solve a problem in as many ways as possible.” When you have doubt on schoolwork, you’d better ____________.
| A．ask your teacher for help |
| B．make it clear by yourself |
| C．ask your classmates to help you |
| D．ask your parents for help |
What’s Manu Kapur educational idea on learning new knowledge?
| A．Give students much help as soon as possible. |
| B．Let students learn it on themselves in one way. |
| C．Let students learn it by themselves in the same way. |
| D．Let students learn it for themselves in different ways. |
How did Kapur check his idea on better learning?
| A．By asking questions. |
| B．By solving art problems. |
| C．By group comparations. |
| D．By solving science problems. |
What is most important in learning knowledge?
| A．Getting the teacher’s help. |
| B．Getting the student’s help. |
| C．Grasping the learning course. |
| D．Receiving the final solution. |
Sailing Through History
A group of 1,309 passengers boarded the MS Balmoral on Sunday, in Southampton, England, on a voyage to retrace the path of the Titanic. The Titanic was the biggest ship in the world when it sailed on its ill-fated maiden voyage in 1912. Of the 2,227 passengers and crew aboard, more than 1,500 died. The ship, which was headed to New York City, carried the rich and famous on its first voyage. It also carried immigrants, who were seeking a better life in America.
Relatives of people who sailed on the Titanic, historians, authors and people fascinated by the story of the unsinkable ship, are on the Balmoral. They want to remember the doomed ship and those who died on her first and last voyage. The historic liner had set sail on April 10, 1912, from Southampton. Late at night on April 14, she hit an iceberg. In the early morning hours of April 15, the Titanic sank.
The Balmoral is following Titanic’s original route from Southampton. First, the modern-day cruise liner docked in the port of Cherbourg, France, where the Titanic had picked up more passengers. On Monday afternoon, the Balmoral stops in Cobh, Ireland, the Titanic’s last port of call before sailing to New York.
Balmoral will then cruise the North Atlantic Ocean to the location where Titanic hit an iceberg that ripped the ship’s hull(外壳). On Sunday, April 15, at 2:20 a.m.—the time the Titanic went down—passengers and crew will hold a memorial service. The next two days will be spent in Halifax, Canada, where many victims of the sinking are buried. Then, the Balmoral will reach its final destination in New York City, where Titanic was supposed to dock—but never did.
Until today, several teams of divers have explored the site. They have recovered some items such as dishes and silverware and put them on public display. And more trips are planned to the wreckage in the future. The Titanic and its passengers and crew have been remembered in books, movies and TV programs. But there’s a much more important contribution that Titanic gave us. After she sank, lawmakers and shipbuilders made ships safer. It took a terrible tragedy to make ship travel safer for all.How many passengers in Titanic survived at last?

Have you ever intended to be fully absorbed in your work but found yourself distracted by e-mail, the Internet and other things throughout the day? According to the survey made by a famous university in the USA, most people have the experience.
"People often lose their concentration when they are bored, of course, but also when they are engaged in challenging tasks," says Peter Bregman, the head of the survey. "They sometimes have a feeling to escape from what's difficult or boring, so they jump out," he says. The part of the brain devoted to attention is connected to the brain's emotional center. Any strong emotion —quarrels with colleagues, problems at home —can interrupt our attention. Studies over the last decade have shown that too much work to do at a time can easily lead to distraction.
Refocusing is hard for many people. Robert Epstein suggests the following, "Stop and listen to some soft music for a few minutes. Find a good friend or a teacher and say out your matter on your mind. Go for a short walk or take a deep breath, where you breathe in deeply, count to five slowly, hold it and breathe out very slowly." This can "blow out all the tension and the unwanted in your mind to restore your focus."
Take more control by structuring your time and becoming more aware of your behaviors. "Setting the phone alarm to go off every hour is my way of creating awareness," Mr. Bregman says. "You have to inform yourself that you've lost focus in order to do something about it." Starting the day with a to-do list is also important, such as when to eat, when to go to the gym or take a walk. But if it's overly ambitious, you will put yourself in a state of anxiety, which makes it hard for the brain to concentrate. "Choosing three or four things as your priority for the day allows your brain to settle down and focus," he says.According to the passage, which is NOT the reason why some people can be distracted from their work?
| A．They don't want to be devoted to their work. |
| B．They are disturbed by the Internet and other things. |
| C．They can't find interest in their work. |
| D．They feel their work is too hard for them. |
Which incident might NOT interrupt your attention?
| A．You were scolded by your teacher. |
| B．You had words with your good friend. |
| C．You went to school at six as usual. |
| D．Your mother and father had a quarrel. |
What's the meaning of the underlined word "restore" in the passage?
| A．recover | B．reform | C．release | D．react |
According to Robert Epstein, how can we refocus on what we should do?
| A．Listen to rock music for some time. |
| B．Turn to your good friends or teachers for help. |
| C．Run around the playground for some time. |
| D．Take a breath from time to time. |
If you want to teach your children how to say sorry, you must be good at saying it yourself, especially to your own children. But how you say it can be quite tricky.
If you say to your children “I’m sorry I got angry with you, but …” what follows that “but” can render the apology ineffective: “I had a bad day” or “your noise was giving me a headache ” leaves the person who has been injured feeling that he should be apologizing for his bad behavior in expecting an apology.
Another method by which people appear to apologize without actually doing so is to say “I’m sorry you’re upset”; this suggests that you are somehow at fault for allowing yourself to get upset by what the other person has done.
Then there is the general, all covering apology, which avoids the necessity of identifying a specific act that was particularly hurtful or insulting, and which the person who is apologizing should promise never to do again. Saying “I’m useless as a parent” does not commit a person to any specific improvement.
These pseudo-apologies are used by people who believe saying sorry shows weakness. Parents who wish to teach their children to apologize should see it as a sign of strength, and therefore not resort to these pseudo-apologies.
But even when presented with examples of genuine contrition, children still need help to become aware of the complexities of saying sorry. A three-year-old might need help in understanding that other children feel pain just as he does, and that hitting a playmate over the head with a heavy toy requires an apology. A six-year-old might need reminding that spoiling other children’s expectations can require an apology. A 12-year-old might need to be shown that raiding the biscuit tin without asking permission is acceptable, but that borrowing a parent’s clothes without permission is not.According to the author, saying “I’m sorry you’re upset” most probably means “_______”.
| A．You have good reason to get upset |
| B．I’m aware you’re upset, but I’m not to blame |
| C．I apologize for hurting your feelings |
| D．I’m at fault for making you upset |
We learn from the last paragraph that in teaching children to say sorry _______.
| A．the complexities involved should be ignored |
| B．their ages should be taken into account |
| C．parents need to set them a good example |
| D．parents should be patient and tolerant |
It can be inferred from the passage that apologizing properly is _______.
| A．a social issue calling for immediate attention |
| B．not necessary among family members |
| C．a sign of social progress |
| D．not as simple as it seems |
