One in 400 children in the United States has diabetes(糖尿病). And the most difficult thing for the young diabetic patients is that many of them don’t have a clear idea when they need to take insulin(a drug used in treating diabetes).The parents of one Long Island boy found the perfect solution—Hero, a specially trained dog that can discover when a diabetic is in trouble and find help.
Johnny Pion, eight years old, is a poor kid that was told he was a diabetic in 2008. He can’t do without insulin. His blood-sugar levels should be closely checked. He even can’t go out to play without his mom or dad fearing he might need help.
With Hero in her new home, Johnny’s parents may worry a little less. They received the news about Hero on the newspaper. The dog cost around $20,000. With the help of friends and family, the Pions brought Hero home from Warren Retrievers in Virginia. Mary Campbell. Hero’s trainer, said the dog could discover the slightest changes in blood sugar by her sense of smell.“Humans have 5 million smell receptors(感受器)； dogs have 5 billion smell receptors,”she said.
When the dog discovers something’s wrong, she’ll rub(蹭)her head against Johnny’s legs. If he doesn’t answer her, Hero knows to look for Johnny’s mom and dad. Hero even could ring up 911.
On their first night, Johnny’s was comfortably sleeping in his own bed with Hero and not with his parents for the first time. Night time is very important because blood sugar goes unchecked while sleeping. Now Hero is a round-the-clock nurse.Young people with diabetes have difficulty .

Nuclear power's(核能的) danger to health, safety, and even life itself can be described in one word; radiation(辐射). Nuclear radiation has a certain mystery about it, partly because it cannot be detected (探测) by human senses. It can't be seen or heard, or touched or tasted, even though it may be all around us. There are other things like that. For example, radio waves are all around us but we can't detect them, sense them, without a radio receiver. Similarly, we can't sense radioactivity without a radiation detector. But unlike common radio waves, nuclear radiation is not harmless to human beings and other living things. At very high levels, radiation can kill an animal or human being completely by killing masses of cells (细胞) in important organs (器官). But even the lowest levels can do serious damage. There is no level of radiation that is completely safe. If the radiation does not hit anything important, the damage may not be significant. This is the case when only a few cells are hit, and if they are killed completely. Your body will replace the dead cells with healthy ones. But if the few cells are only damaged, and if they reproduce themselves, you may be in trouble. They reproduce themselves in an unusual way. They can grow into cancer. Sometimes this does not show up for many years.
This is another reason for some of the mystery about nuclear radiation. Serious damage can be done without the knowledge of the person at the time that damage has occurred. A person can be irradiated(放射治疗) and feel fine, then die of cancer five, ten, or twenty years later as a result. Or a child can be born weak or easy to get serious illness as a result of radiation absorbed by its grandparents. Radiation can hurt us. We must know the truth.According to the passage, the danger of nuclear power lies in __________.
| A．nuclear mystery | B．radiation detection |

Which of the following can be best inferred from the passage?
| A．The importance of protection from radiation cannot be too overemphasized (过分强调). |
| B．The mystery about radiation remains unsolved. |
| C．Cancer is mainly caused by radiation. |
| D．Radiation can hurt those who do not know about its danger. |

Lisa Pina never thought she would need the fire safety training she received during her apprenticeship (学徒期) as a union painter and dry waller. On Friday morning，she was thanking God she had it.
On Thursday night，while Pina was babysitting her granddaughter，nephew and two nieces in her sister’s apartment，she smelled smoke and realized the apartment building was on fire. When her 4yearold granddaughter Ilean Garcia began saying，“We’re going to die，”she knew she had to act.Pina,39，first sealed the door，and then told all four children to get on the floor. After calling 911，she told the children to start singing and promised them all treats as soon as they reached safety. “I said，‘OK，we’re going to lie down and we’re all going to play a game，’” Pina said. “We all started singing our ABCs and 123s.I was just trying to make it fun.” Pina patiently waited，and a few minutes later，Riverside County sheriff’s deputies (治安官的助手) arrived. Pina，Ilean,8yearold Gabriel Parga,5yearold Aubreyana Parga and 4yearold Meriyah Parga were all trapped on the second floor as flames filled the first story. Pina did the only thing she could. She opened the window and dropped the children，onebyone，into the arms of the sheriff’s deputies about 15 to 20 feet below. “I just needed to keep the kids calm so they wouldn’t be afraid，”Pina said.“I was deathly afraid inside，but I couldn’t let them know that.”[Not long after dropping the children out of the window，firefighters arrived with a ladder and rescued her. Ten people were treated at the scene for suffering smoke，but nobody was seriously injured.The text is mainly about________.

When I asked my daughter which item she would keep; the phone, the car, the cooker, the computer, the TV, or her boyfriend, she said “the phone”. Personally, I could do without the phone entirely, which makes me unusual. Because the telephone is changing our lives more than any other piece of technology.
Point 1 The telephone creates the need to communicate, in the same way that more roads create more traffic. My daughter comes home from school at 4:00 pm and then spends an hour on the phone talking to the very people she has been at school with all day. If the phone did not exist, would she have anything to talk about?
Point 2 The mobile phone means that we are never alone. “The mobile saved my life,”says Crystal Johnstone. She had an accident in her Volvo on the A45 between Otley and Skipton. Trapped inside, she managed to make the call that brought the ambulance(救护车) to her rescue.
Point 3 The mobile removes our secret. It allows marketing manager of Haba Deutsch, Carl Nicolaisen, to ring his sales staff all round the world at any time of day to ask where they are , where they are going, and how their last meeting went.
Point 4 The telephone separates us. Antonella Bramante in Rome says, “We worked in separate offices but I could see him through the window. It was easy to get his number. We were so near——but we didn’t meet for the first two weeks!”
Point 5 The telephone allows us to reach out beyond our own lives. Today we can talk to several complete strangers simultaneously ( 同时地) on chat lines (at least my daughter does. I wouldn’t know what to talk about). We can talk across the world. We can even talk to astronauts (if you know any) while they’re space-walking. And, with the phone line hooked up to the computer, we can access(存取) the Internet, the biggest library on Earth.How do you understand‘Point 1 —The telephone creates the need to communicate,…’？
| A．People don’t communicate without telephone. |
| B．People communicate because of the creating of the telephone. |
| C．People communicate more since telephone has been created. |
| D．People communicate more because of more traffic. |
Which of the following best shows people’s attitude towards mobile phones?
| A．Mobile phones help people deal with the emergency. |
| B．Mobile phones bring convenience as well as little secret to people. |
| C．Mobile phones are so important and should be encouraged. |
| D．Mobile phones are part of people’s life. |
It is possible to talk to several complete strangers simultaneously through _______.
| A．the TV screen |
| B．a fax machine |
| C．the phone line hooked up to the computer |
| D．a microphone |
The best heading for the passage is _________.

Envy seems to be bad-but it doesn't have to be. Researchers are finding that, if approached the right way, there can actually be an advantage.
Psychologists classify envy in two ways: negative and positive. With positive envy, you are motivated by another person's success and struggle to follow it. With negative envy, you want to cut the advantaged person down so you look better by comparison. Let's say you feel sufferings of envy after your rival(对手) at another firm gets promoted. Negative envy might drive you to destroy his success, but positive envy would inspire you to work harder and get promoted, too.
Studies show positive envy can be a great motivator(动力). In a 2011 study published in the Personality and Social Psychology Bulletin, researchers in the Netherlands conducted a series of experiments with more than 200 university students. Researchers found that when they caused feelings of positive envy----as opposed to admiration or negative envy----in the students, it drove them to want to study more and perform better on a test measuring creativity and intelligence. While admiration may feel better, the researchers found, it doesn't motivate performance like the pain and frustration of envy.
“Those painful sufferings of envy are there for an evolutionary(进化的) reason,” says Texas Christian University researcher Sarah E. Hill, “warning us that someone has something of importance to us.” Building on this theory, Dr. Hill and others conducted a series of experiments, published in the Journal of Personality and Social Psychology, to test whether envy improves attention and memory----the tools needed to copy a rival's steps to success. In one experiment, half of the participants were asked to recall past feelings of envy; the other half weren't. The two groups were then shown mock(模拟的) interviews of imaginary peers. The group filled with envy paid closer attention and better recalled details about the interview subjects. In other words, envy made them more astute（机敏的）. Not only can envy motivate us to reach for higher goals, it may even give us the cognitive push to get there.What’s the bad effect of negative envy?
| A．It makes you lose heart and gets discouraged. |
| B．It has you feel motivated. |
| C．It makes you harm or hurt others on purpose. |
| D．It reminds you to struggle to follow your dreams. |
What’s the benefit of positive envy?
| A．It inspires you to find a possible rival to try to defeat them. |
| B．It encourages you to work harder with a positive attitude. |
| C．It won’t hurt your opponents in the same firm. |
| D．It won’t destroy your success at another firm. |
Compared to admiration, positive envy can__________.
| A．make you feel worse in all sides |
| B．be more likely to get you to admire others |
| C．make you feel the pain in your performance |
| D．be more likely to get you inspired to get success |
What is the main idea of the passage?
| A．Envy seems to be bad. |
| B．Keep your envy in secret. |
| C．Make full use of positive envy. |
| D．Forget about your envy now. |
