The system, called Driver Alert, aims to reduce deadly road accidents by 20% - 40% that are caused by tiredness. Airline pilots can also use it to reduce the 30% of all pilot-error accidents that are related to fatigue.
Driver Alert is based on a computerized wristband. The device, worn by drivers or pilots, gives out a sound about every four minutes during a car journey. After each sound the driver must respond by squeezing the steering wheel. A sensor in the wristband detects this pressing action and measures the time between the sound the driver’s response.
Tiredness is directly related to a driver’s response time. Usually, a watchful driver would take about 400 milliseconds to respond, but once that falls to more than 500 milliseconds, it suggests that the driver is getting sleepy.
In such cases the device gives out more regular and louder sounds, showing that the driver should open a window or stop for a rest. If the driver’s response continues to slow down, the sounds become more frequent until a nonstop alarm warns that the driver must stop as soon as possible.
The device has been delivered to the department’s laboratories for testing. If these tests, scheduled for six months’ time, are successful, the makers will bring the product to market within about a year.
小题1:According to the text, Driver Alert ______.
| A．aims to reduce tiredness-related accidents |
| B．has gone through testing at laboratories |
| C．aims to prevent drivers from sleeping |
| D．has been on sale for 12 months |
| A．By sounding a warning. | B．By touching the wristband. |
| C．By checking the driving time. | D．By pressing the steering wheel. |
| A．about 400 milliseconds | B．below 500 milliseconds |
| C．over 500 milliseconds | D．about 4 minutes |

举一反三
I will admit that I have no problem coming up with rules. To me they make life easier and they leave no room for questioning. What can be more difficult, however, is giving my teens their freedom. I guess there are really two primary reasons for this. One is that I sometimes am afraid to give them freedom. The second is that I’m not always so sure what the freedom should be.
It helps that I have a husband with whom I can discuss these problems. We talk about them, give our thoughts and then we come up with an agreement. Sometimes one of us might be more unwilling but we know that there comes a time when we really do have to learn how to let go of the reins (缰绳) a bit.
If we try to make life have nothing but rules, we are more likely to see our teen’s rebelling (反抗). They need to know that while we do have certain expectations, we also trust them to begin making their own choices and decisions. How else can they do that unless they are given the space and room to do it?
It’s really all about balance and I will be the first to admit that it can be a challenge to carry out. However, it is a necessary part of growing up. Yes, teens definitely need rules but they also need freedom.
小题1:According to the text, we can infer that the writer________.
| A．refuses to give her children freedom |
| B．finds it difficult to make rules |
| C．doesn’t have a good relationship with her children |
| D．has trouble in giving freedom to her children |
| A．strong-willed | B．rebellious | C．weak | D．independent |
| A．Rules are difficult to make for parents. |
| B．Rules and freedom are similarly important. |
| C．We should give children freedom as much as possible. |
| D．Rules are more important than freedom. |
| A．Problems. | B．Children. | C．Rules. | D．Reasons. |
Consider this for a moment: Wearing a helmet will absolutely do nothing to prevent you from getting hit by a car. Surely, a helmet might help you if you get hit, but you No.1 goal should be to avoid getting hit. Plenty of cyclists were killed by cars__________. However, if they had ridden without helmets, yet followed the guidelines listed below, they might still be alive today. So they saying that wearing a helmet is the first and last word in bike safety is, to some degree(在一定程度上), wrong.
The most common bike safety advice is “follow the law”. Ridiculously, most people are already aware that it’s stupid to race through a red light at a crossroads. As a result, it’s clear that the “follow the law” advice isn’t that helpful, either. In addition, following the law is not enough to keep you safe. Here’s an example: The law tells you to ride on the right, but if you ride too far to the right, someone started a parked car could open their door right in front of you and motorists pulling out of driveways and parking lots will be less visible. In that case you were following the law, but could still have been hit.
Then what should we remember in order to keep safe when riding a bike? I will tell you about it in the following paragraph.

The main reason for violence acts are the films and cartoons that fill the children’s time． They want to do everything they watch on TV and never think of the consequences, and they may hurt a classmate or a teacher．
On the other hand, parents are not fully satisfied with the children’s results obtained in classes and they consider private classes would have better results. When a teacher has to watch 30 students in class he can’t probably see what each of them is doing, how he is writing, or if he understands the explanations． At home the teacher can explain in details everything the child doesn’t understand as many times as he considers proper. And many times the child grows fond of the teacher at home, who becomes his best friend, and who helps him whenever he needs someone to talk to.
However, the best solution would be a mixture between the education received at school and that at home, because school makes children communicate and socialize． Keeping a child at home for fear there might happen something bad to him only makes the child’s character weak and prevents him from knowing what real life is． Staying in a crystal ball only does harm to the child．
All in all, schools have been created to help children, not to harm them, so it’s best to keep children in these special places, where they learn, laugh, have fun and make new friends
小题1:The writer’s purpose in writing the text is to ________
| A．teach parents the ways to keep their children safe |
| B．show solutions to developing children’s character |
| C．analyze an education problem and give opinions |
| D．explain the main reason for violence acts in schools |
| A．Advantages and Disadvantages of Private Classes |
| B．Who is to Blame, Parents or Schools? |
| C．Which Is Better, School Study or Home Study? |
| D．The Relationship between Teachers and Children |
| A．A toy that can be used for entertainment |
| B．A safe and comfortable environment |
| C．A round object that is made of crystal |
| D．An obstacle that is hard to overcome |
| A．violence TV programs have bad effects on children’s behavior |
| B．the teacher at home is more patient than the teacher at school |
| C．children today are weak from lack of sense of right and wrong |
| D．there are too many students in class for a teacher to teach |
We all stood there just inside the door of the Wal-Mart. We waited, some patiently, others annoyed because nature messed up their hurried day. I got lost in the sound and sight of the heavens washing away the dirt and dust of the world.
Her voice was so sweet as it broke the hypnotic trance (昏昏欲睡) we were all caught in. “Mom, let’s run through the rain,” she said.
“ No, honey. We’ll wait until it slows down a bit.” Mom replied.
This young child waited about another minute and repeated, “Mom, let’s run through the rain. ”
“We’ll get soaked if we do,” Mom said.
“ No, we won’t, Mom. That’s not what you said this morning,” the young girl said as she tore at her Mom’s arm.
“This morning? When did I say we could run through the rain and not get wet?”
“Don’t you remember? When you were talking to Daddy about his cancer, you said, If God can get us through this, he can get us through anything!”
The entire crowd stopped dead silent. I dare say you couldn’t hear anything but the rain. We all stood silently. No one came or left in the next few minutes. Mom paused and thought for a moment about what she would say.
Now some would laugh it off and scold her for being silly. Some might even ignore what was said. But this was a moment of affirmation in a young child’s lifetime when innocent trust can be developed so that it will bloom into faith. “Honey , you are absolutely right. Let’s run through the rain. If get wet, well maybe we just need washing.” Mom said. Then off they ran.
We all stood watching, smiling and laughing as they rushed past the cars and they held their shopping bags over their heads just in case. They got soaked. But they were followed by a few who screamed and laughed like children all the way to their cars. And yes, l did. I ran. I got wet. I needed washing.
You may lose your material possessions, your money and even your health, but no one can ever take away your precious memories. So don’t forget to make time and take the opportunities to make memories.

| C．She was in despair and pretended to forget what she said. |
| D．Her daughter completely understood the situation her family was in. |

| A．Be a Determined Mother | B．Wait in the Rain |
| C．Have a wonderful experience | D．Run Through the Rain |
“The brain is not passive while you sleep,” scientist Anat Arzi said. “It’s quite active. You can do many things while you are asleep.”
Arzi and her coworkers didn’t try to teach the sleeping volunteers any complex information, like new words or facts. Instead, the scientists taught volunteers to make new connections between smells and sounds.
When we smell something good, like a flower, we take deep breaths. When we smell something bad, we take short breaths. Arzi and her co-workers based their experiment on these reactions.
Once the volunteers fell asleep in the lab, the scientists went to work. They gave them a whiff of something pleasant and meanwhile played a particular musical note. They didn’t wake up, but they heard—and sniffed(吸气) deeply. Then the scientists gave the volunteers a whiff of something terrible and played a different musical note. Again, the volunteers heard and smelled—a short snort this
time—but didn’t wake up. The researchers repeated the experiment.
After just four repetitions, volunteers made a connection between the musical notes and their paired smells. When the scientists played the musical tone that went with good smells, the sleepers breathed deeply. And when the scientists played the musical tone that went with bad smells, the sleepers breathed briefly—despite there being no bad smell.
The next day, the volunteers woke up with the sound-smell connection. They breathed deeply when hearing one tone and cut their breaths short when hearing the other, which must have been unusual for them. Imagine walking down the street and taking a deep breath upon hearing a particular sound!
小题1:In the study, the volunteers were taught _______.
| A．to become active during sleep |
| B．to tell the difference between smell |
| C．to learn new words and scientific facts |
| D．to make sound-smell connections |
| A．They took a deep breath. | B．They had a wonderful dream. |
| C．They woke up at once. | D．They took a short breath. |
| A．learned how to play to musical tones |
| B．forgot what happened during their sleep |
| C．continued with the sound-smell connection |
| D．changed their reaction when hearing. |
| A．special smells and sounds can improve our memory. |
| B．our brain can actually learn something new during the sleep. |
| C．the volunteers will always hear similar sounds in the street. |
| D．our brain can tell the difference between smells during the sleep. |
| A．A short sleep can improve our memory and sharpen our thinking. |
| B．Arzi and her coworkers didn’t try to teach the sleeping volunteer some simple information. |
| C．When the volunteer smelt something terrible, they didn’t wake up. |
| D．After four repetitions, volunteers made a connection between the musical notes and their pared smells. |
