Most people above 16 years old have a strong wish that they should drive on the road by themselves. Thus getting a license is an exciting time in their life. Ultimate Drivers is there to help your teen learn the rules of th road and gain important driving experience.

What We Offer

Ultimate Drivers’ program will help students prepare for their road test and give them the skills they need to become lifelong safe and defensive drivers.

The beginner program offers 20 hours of in-class training, 12 hours of homework assignments and 8 hours of in-car training. Each in-class training lasts 120 minutes and each one-on-one in-car training 80 minutes. What's more, students can be picked up for free from home, work or school.

What You Need Know

Students can complete the classroom part of the course in just two weekends or if it better suits their schedules they can take it during the evenings on weekdays. There are also classes offered during the holiday break.

Students can start taking the classroom part of the driving training without the G1 license, but do need it by the time they' re ready to start the in-car driving lessons.

What Extra Benefits Are

The beginner drivers can gain much through the program. After that they’ ll receive student testimonials(证明书). The testimonials show teenagers who have taken the course feel more confident in their abilities and many believe they couldn't have passed the road test without it.

Sign up before April 5th. and students can get an insurance discount!

1. How many times does the program offer in-class training?

A.20. B.10. C.12. D.8.

2. What do students need to do to have in-car driving lessons?

A. Sign up before April 5th. B. Finish the classroom part.

C. Get the G1 license. D. Receive a student testimonial.

When Liam Pope-Lau fell into the ocean during a sailing lesson, he had no idea what he was in for. “I just remember how cold it was,” Liam recalls. “It really scared me and shook me up.” Thankfully, he was wearing a life jacket, but the water was freezing.

Liam's scary experience inspired him to team up with his friend, Fraser Tuck, in his Grade 6 science class at the time. Together they came up with the idea of“LifeHeat”,- - a self-heating life jacket that could one day help someone in a similar situation. During the first phase, they concentrated on finding a chemical that creates heat upon contact with water. After a series of investigations, Liam and Fraser came across calcium chloride(氯化钙), It soon became LifeHeat's primary chemical component, which allowed the life jacket to remain warm underwater.

Over the next two years, Fraser and Liam built 13 prototypes (模型) of LifeHeat. But instead of building multiple life jackets from scratch(从零开始), the two focused on creating an attachable pouch(荷包). When the pouch came in contact with water, it could heat the body's core. For each prototype, Liam and Fraser experimented with different materials that could contain calcium chloride while still allowing its heat to escape. In the process,they experienced countless failures which, however, led them to be more creative.

The two have entered their many prototypes into several science competitions over the last two years. InNovember last year, Liam and Fraser won two awards at a big science fair. They are now taking the feedback they received from experts and applying it to their next prototype. Liam and Fraser anticipate turning their invention into a business.

As for future inventors, Fraser and Liam have advice for kids who want to create their own new technology.“Don't be afraid to try it out. because you never know where it could end up,” said Liam. “Go for it before someone else can steal your idea,” added Fraser with a laugh.

4. What gives Liam the desire to invent the“LifeHeat”?

A. A science class. B. An amusing experience. C. A special life jacket. D. A cold struggle in water.

5. What do the Fraser and Liam focus on initially?

A. Finding a suitable chemical. B. Building multiple life jackets.

C. Creating an attachable pouch. D. Testing the prototypes of LifeHeat.

6. What can we learn about the“LifeHeat”?

A. It has been put am the market. B. It is invented through trial and error.

C. Iwo of its prototypes won awards at a science fair. D. The attachable pouch is the most important part of it.

A surprising finding that the inner core may recently have slowed down was published in Nature Geoscience.Let's get to the core of how the Earth works to better understand the scientific findings.

The Earth is composed of several layers: the crust, which is the surface we live on; the mantle, which begins below the crust and ends at the outer core; the outer core, which is made of hot liquid metal; and the inner core,which is believed to be a solid metal ball of iron and nickel. Scientists believe that the inner core may“floats” in the liquid metal and rotate(转动) independently of the rest of Earth's layers.

The study's authors propose the Earth's inner core may be experiencing a slowdown and that this difference can be measured by observing a change in how seismic waves(地震波) pass through the Earth's center during an earthquake. Older data shows a lot of change in the wave patterns while passing through the core, but recent data shows the changes are no longer as visible. After analyzing the patterns of seismic waves through the decades,scientists theorize the Earth's inner core changes its rotational speed over time. Different studies have concluded that these changes in speed follow a pattern that may range from 20 to 70 years. The observed changes in the inner core's behavior are likely caused by magnetic forces acting on it, which is produced by the movement of liquid iron in the outer core. Although the core’ s spin seems to be independent, we know that all layers of the Earth interact and experience effects from each other.

We have much more to learn about Earth and its physical processes. Scientists say that many years of continuous recording and study of seismic data are necessary to get answers. Until then, we must be patient. The investigation of this phenomenon will definitely lead us under the surface and into the core of understanding our planet!

8. Which layer is surrounded by the liquid metal?

A. The crust. B. The mantle. C. The outer core. D. The inner core.

9. Which of the following may be a reason for the inner core’ s slowdown?

A. Magnetic forces. B. Seismic waves. C. Human activities. D. Rotation patterns.

10. What does the author think of the research into the Earth's core?

A. Promising. B. Ridieulous. C. Pointless. D. Questionable.

11. What would be the best title for this text?

A. How does the Earth Work? B. Is the Earth's Core Slowing Down?
