2022高考一轮复习：选择性必修四 Unit 2 教材串讲提升练
Ⅰ. 阅读理解
A
Canadians are blessed with an abundance of natural wonders with enough lakes, mountains and rivers to explore for a lifetime. We've also got some of the most amazing waterfalls on Earth.
Horseshoe Falls — Niagara Falls, Ontario
Niagara Falls are the most famous waterfalls in Canada — and understandably so. Actually they are made up of three different falls, and the fittingly named Horseshoe Falls is the only one located on the Canadian side, which is the most powerful in North America. Multiple viewing options are available including tourist ships and sightseeing buses.
Nailicho (Virginia Falls) — Nahanni National Park Reserve, Northwest Territories
Coming in at twice the height of Niagara Falls, this massive waterfall is located on the South Nahanni River in the Northwest Territories. The remote location means it receives only about 1,000 visitors per year who must make their way by either boat or floatplane.
Takakkaw Falls — Yoho National Park, British Columbia
Takakkaw translated from Cree loosely means “the magnificent (壮丽的)”， and it's a suitable word for the second-highest waterfall in Canada. After a steep drive up a winding road, Takakkaw Falls is only a short distance from the parking lot along a wheelchair accessible path.
Bridal Veil Falls — Bridal Veil Falls Provincial Park, British Columbia
Pretty and delicate, Bridal Veil Falls is located just east of Chilliwack, British Columbia, and really does look like its name, with water gently pouring over smooth rock. An easy 15-minute walk to the waterfall takes you through rich leaves. Tables are available to have a meal outdoors, and there are lots of opportunities for viewing wildlife along the way.
1. What do we know about Horseshoe Falls
A. It is easily accessible.
B. It consists of three falls.
C. It limits tourist numbers.
D. It crosses North America.
2. How can visitors go to Takakkaw Falls
A. By tourist ship. B. By cable car. C. By floatplane. D. By car.
3. What can visitors do in Bridal Veil Falls
A. Swim. B. Camp. C. Picnic. D. Hunt.
B
A new device works like a solar panel, except that it doesn't harvest energy from the sun. It absorbs energy from the cold night sky.
A prototype(原型) of the device produced enough electricity at night to power a small light bulb. A bigger version might one day light rooms or charge phones. It could also power electronics in remote or low-resource areas that lack electricity.
The device makes use of the temperature difference between Earth and outer space. It then uses that difference to create electricity. As long as one side of it is cooler than the other, the generator can produce electricity. The cooler side faces the sky and is attached to an aluminum plate. That plate is sealed beneath a transparent cover and surrounded with insulation (隔热材
料) to keep out heat. The bottom of the generator is attached to an exposed aluminum plate. That plate is warmed by the local air. At night, the top plate can get a couple of degrees Celsius cooler than the bottom of the generator.
Researchers tested a 20-centimetre prototype one clear December night in Stanford，California. The generator produced up to about 25 milliwatts of power per square metre of the device. That was enough power to light a small light-emitting diode, or LED bulb. Further improvements might increase its production to at least 500 milliwatts per square metre. To
do that, the system might need more insulation around the cool top plate.
The device also could help power remote weather stations or other environmental devices, says Aaswath Raman. He is a material scientist who worked on the device at the University of California, Los Angeles. “This may be useful in polar regions that don't see sunlight for months at a time，” Raman says. “If you have some low-power load and you need to power it through three months of darkness, this might be a way.”
4. What can we know about the new device
A. It gains energy from the sun.
B. It's been widely used in life.
C. It is cooler than a solar panel.
D. It'll be popular in special areas.
5. What does the author mainly talk about in Paragraph 3
A. Application fields of the device.
B. The developing process of the device.
C. The working principle of the device.
D. Significant effects of the device.
6. How can the device produce more electricity
A. By putting more insulation around the top plate.
B. By using it in extremely cold and clear nights.
C. By attaching the bottom plate to a warm plate.
D. By covering the top plate with a transparent lid.
7. What could be a suitable title for the text
A. A Device Using the Cold Night Sky to Produce Electricity
B. A Device Bringing New Hope for Those in the Cold Night
C. The Difference Between a Solar Panel and a New Device
D. The Temperature Difference Between Earth and Outer Space

Reasons Why You Should Go to College
There are many important reasons why a young person should consider going to college other than just the potential financial rewards.
Have a new beginning. Sometimes you just need a fresh start in life. 1.________ Going to college is a perfect opportunity to break out of that old shell and become someone totally new.
Learn something you like. It is true that many degrees do not prepare you for the real world in terms of what you learn. 2.________ Take some time to enjoy learning what you are truly passionate about.
3.________ While parents may be worried about their children's new-found freedom, teens are generally pretty excited about it. College can give a young person the independence they think they need as well as the opportunity to start making their own decisions.
Develop your interest. If you are interested in politics, you can get involved in the student government. If you want to be a journalist, here is an opportunity to get a head start by working for the school paper. 4.________
5.________ For some people, the number one reason to go to college may simply be the opportunity to move to a new place. Many people living in the north may want to go to school in the south to escape the cold. Others may just want to get out of a small town and see the world. Even moving from a childhood house to a dormitory in a local college campus can be a great change.
A. Be independent.
B. Figure out who you are.
C. Get a change of scenery.
D. Enjoy the best time of your life in college.
E. Whatever you are interested in, there is a group for it.
F. However, a college education is an opportunity to learn what you love.
G. You need to give up your old habits and your old self, and become the person you want to be.
Ⅲ. 应用文写作
假定你是李华，你与班上来自英国的交换生Mike 约定周日去购买他喜欢的中国历史书籍，但你临时有事不能赴约。
请你给他用英语写一封邮件说明情况，内容包括：
1. 表示你的歉意；
2. 解释失约原因；

Dear Mike，
Deeply sorry for not being able to go to the bookstore with you for your favourite books related to the Chinese history this Sunday. I'm writing in an effort to make a change to our plan.
Just now I was informed to attend an important voluntary activity to be held on the very day. So would it be possible for us to go there another time, let's say, next Sunday morning If so, we'll have enough time to make a choice about which books to buy.
Please let me know your decision as soon as possible.
Yours，
Li Hua
