Every driver is familiar with the horrible blind spot problem. However, it is more than just an annoyance. According to the National Highway Traffic Safety Administration, over 840,000 car accidents occur due to the blind spot. Those zones which cannot be directly observed by the driver often causes incidents that result in serious property damage and in some cases even death.

While drivers can take precautions such as adjusting the driver's seat and side mirrors properly, installing backup cameras and so on, they won't remove the invisible spots completely. Therefore, the driver will always have to carry the responsibility of being constantly aware of blind spots because failing to do that can lead to accidents.

Luckily, now there's a solution to that and it comes from a 14-year-old girl, who doesn't even have a driver's license yet. However, not being able to drive didn't prevent Alaina Gassier from understanding the important issue of traffic accidents resulting from blind spots. In fact, she knows the problem so well that she actually solved it for us. And the way she did it is nothing but genius.

Her project is called "Improving Automobile Safety by Removing Blind Spots'* and work in a relatively simple way as she explained: "I did that by having a camera behind the A — pillar of a car and the camera sent the video to a projector that projected (投射)the image onto the pillar essentially making it invisible and making the driver see behind it."

To complete this invention, she used easily attainable materials such as a webcam, projector, and 3D-printed materials that project the view from outside your vehicle onto the blind spots of your car.

Gassier was awarded for her life-saving invention. It earned her the top place in a nationwide competition for middle schoolers with the $25,000 Samueli Foundation Prize in honor of overall STEM (Science, Technology, Engineering, Mathematics) excellence.

Drivers who drive a little too close to cyclists on the road could soon be caught on the spot. A new technology adopted by legal departments in Ottawa could help carry out legal distance between bikers and cars on the road.

The device, which is fixed on a bicycle’s handlebars like a bike bell, uses sonar(声呐) technology to measure the distance between the bike and passing cars. The device will make a loud noise if the car is within one meter of the bike, the legal limit in the city of Ottawa, allowing the police rider to radio ahead to his colleagues so that the driver can be pulled over. “The safety of all road users is extremely vital, including cyclists. These cycling changes are directed at encouraging cycling, promoting road safety, and sharing the road,” said Rob Wilkinson, coordinator of the Safer Roads Ottawa Program.

The authorities started the program last week with a single sonar device. One police officer rode the bike bearing the device around the city on Tuesday to prove the effectiveness(有效性) of the technology. Within a few minutes of riding, the device was beeping, registering that two drivers had violated the one-meter distance requirement. The drivers were pulled over and given brochures informing them that they had broken the safe distance law.

Wilkinson noted that the device is not currently being used to issue fines, which can go up to $110, and that there are no plans to use it for enforcement(执法)in the future. At this point, its main use is to spread awareness about the safe distance law, which was passed last September in an effort to encourage rider safety and reduce deadly crashes.

1.What will happen if the safe distance is beyond the legal limit?

A.The cyclist will soon be caught on the spot.

B.The police will make the driver stop by the road.

C.The driver will be arrested for driving too fast.

D.The device will at once call the police of itself.

2.What’s the main purpose of using the device?

A.To make the bicycle attractive. B.To encourage people to walk.

C.To guarantee road safety. D.To warn drivers of danger.

3.Which of the following can replace the underlined word “beeping” in paragraph 3?

A.Making a loud noise. B.Receiving an urgent message.

C.Sending a stop signal. D.Radioing the police rider.

4.What does Wilkinson say about the device?

A.It is being developed at present. B.It still has room for improvement.

C.It may be used to fine drivers later. D.It helps reduce traffic accidents.

Despite the fact that it has never been seen almost everyone is familiar with the legendary

unicorn(独角兽). Descriptions of unicorns have been found dating from ancient times. The great philosopher Aristotle theorized that there were two types of unicorn--- the so-called Indian Ass and the Oryx, a kind of antelope. Unicorns are often used in the logo of a noble family, town council or university as their special sign. Even Scotland is represented by a unicorn.

According to the legend, anyone attempting to catch a unicorn had to be extremely cautious

as it has a reputation for being very fierce. A clever trick suggested by unicorn-trappers, in order to catch this magnificent beast without being hurt by its horn, was for the hunter to stand in front of a tree and then to move quickly behind it as the unicorn charged. Hopefully, the creature could then be captured when its horn was stuck in the tree.

When hollowed out and used as a drinking-cup, the unicorn’s horn was said to have the power to offer protection against person. It was believed that nobody could be harmed-by drinking the contents of a unicorn’s horn. Right up until the French Revolution in 1789, the French court was said to have used cups made of “unicorn” horn in order to protect the king. In addition, the horn was said to have medicinal value, so much so that it could be sold for more than ten times the price of the same weight of gold. What, then, was “unicorn” horn? We know at times the rhino(犀牛) was confused with this legendary creature. A drinking-cup supposedly made of “unicorn” horn was discovered to be made of the horn of a rhino.

1.Which of the following is TRUE of the unicorn?

2.To catch a unicorn, the unicorn-trappers had to try all of the following EXCEPT ____.

3.The last paragraph is mainly about ____.

4.In the last paragraph, the word “unicorn ” is in quotation marks (引号)because _____.

In America, drivers’ education is part of the regular high school curriculum. Every student in his or her second year of high school is required to take a class in driver’s education. However, unlike other courses, it is not given during the regular school year. Instead it is a summer course.

The course is divided up into two parts: class time for learning laws and regulations and driving time to practise driving. Class time is not unlike any other class. The students have a text from which they study the basic laws they must know to pass the written driving test that is given to anyone wanting to get a driver’s license.

Driving time is a chance for the students to get behind the wheel (steering wheel) and practice starting steering, backing up, parking, switching lanes, turning corners, and all the other maneuvers (操作) required to drive a car. Each student is required to drive a total of six hours. The students are divided up into groups of four. The students and the instructor go out driving for two hour blocks of time. Thus, each student gets half an hour driving time per outing. The instructor and “driver” sit in the front seats and the other three students sit in the back.

Drivers Ed cars are unlike other cars in which they have two sets of brakes, one on the driver’s side and one on the other side where the instructor sits. Thus, if the student driver should run into difficulties the instructor can take over. The car also has another special feature. On the top of the car is a sign that reads: STUDENT DRIVER. That lets nearby drivers know that they should use extra caution(小心) the student driver is a beginning driver, not very experienced and prone to driving slowly.

After the student has passed the driver’s education course and reached the appropriate age to drive (this age differs in every state but in most cases the person must be 16 years old), they can go to a designated state office to take their driver’s test, which is made up of an eye examination, a written test, and a road test. The person must pass all three tests in order to be given a driver’s license. If the person did well in his or her driver’s education class, he or she will pass the test with flying colors and get a driver’s license.

1. In America, the driver’s course mentioned above___________.

A. is considered as part of the advanced education

A. go out driving for twelve times                     B. spend at least six hours driving

C. drive for two hour blocks of time           D. get half an hour driving
