1 .

4 . _______ can also occur among teenagers, as some data suggest that today’s teenagers are just as _______ as adults, and they can meet many _______ situations. (stress) (所给词的适当形式填空)

5 . Canada must be a nation of talented scientists. World-changing theories and lifesaving chemicals have all been dreamt up and produced here for years. However, little is known about the country’s impressive scientific record.

Canada has another trick as well, unlike many national educational systems. Canadian children seem to be really interested in science, and seem to want to take a scientific career further. Higher education science students are plentiful and science-based documentaries are watched by millions.

So what has Canada achieved? Well, firstly and most importantly is the discovery of insulin (胰岛素) as a treatment for diabetes. It was discovered in Toronto in 1922 by pioneering medical scientists, Frederick Banting and Charles Best. They were both awarded the Nobel Prize a year later.

This wouldn’t be the last Nobel Prize dished out to a medical scientist in Canada. In 1981 another scientist was celebrated, David Hubel, who did the first significant map of the visual cortexes (大脑皮层) of the brain. This meant finding out exactly what part of one’s brain controls brightness, colour, motion and more. Although the majority of this work was carried out in the 60s and 70s, Dr. Hubel continues to work on his theories today with his colleague Torsten Wiesel.

Michael Smith worked out how to change a certain part of the DNA in a plant or animal to change the way it could develop. His research allowed countless researchers from all over the world to develop special bacteria, plants and animals with new desirable qualities or abilities that either did not occur naturally or that would have taken years of breeding (繁殖) trials to achieve.

Canadian success has not just been limited to biology and chemistry. Technology has benefited greatly from Canadian scientists. The CCD microchip, for example, which is widely used in webcams and telescopes was developed by Willard Boyle.

When it comes to science, there is only one country that can truly call itself a country of great scientists, and that country is Canada.

B．All his work was carried out in the 60s and 70s.

D．He took advantage of Wiesel’s map of the visual cortexes of the brain.

4. Michael Smith’s achievement is important in that ________.

A．man can change the way a living thing grows

B．it is widely used in webcams and telescopes

C．it helps Canada become a country of great scientists

D．new bacteria, plants and animals can be found

6 . Our backpacking trips are designed for those who begin to learn backpacking. We have a variety of trips to choose from.

Point Reyes Backpacking

04/28/2022-04/29/2022

Time:7:00 am — 6:00 pm

Come to walk on the “wild” side at Point Reyes National Seashore, one of California’s finest and most well-preserved wildlife areas. You might get a rare glimpse of a fox, a badger, or possibly the fallow deer. As an extra bonus, take a walk down to the beach where you can explore the wonders of tide pool life and possibly view seals or whales.

Tahoe Backpacking

08/17/2022-08/19/2022

Time:7:00 am — 6:00 pm

This section of the Tahoe Rim Trail parallels the well-known “Flume Trail”, which earns its recognition for the breathtaking views of the bright blue waters of Lake Tahoe. Of course, to be able to view all of the lake at once, you will need to hike up in height. The trail reaches a height of 9,000 feet and ends at Tunnel Creek Station, which is just under 6,500 feet. Peak Adventures has planned the daily mileage for this route to be manageable but challenging for beginning backpackers.

Lassen Backpacking

09/01/2022-09/03/2022

Time:7:00 am — 6:00 pm

The park contains a great diversity of landscapes (地貌) including lush marshes, thick forests and lava beds. We will spend three days and two nights backpacking past several streams and lakes. The intensity of this trip is suitable for beginners, but backpackers of all abilities are sure to enjoy the great diversity that Lassen offers.
