（1）“决胜高考”2021 届新高考八省第一次模拟测试之 D篇

It has been four years since the Flashfood App was set to hit Canadian grocery stores and make it easier for

shoppers to buy soon-to-expiry (保质期) food at a discount. Much to my delight, I heard it advertised recently on a

radio station and figured it’s time for an update, especially since people became more aware of food waste’s role in

the climate crisis.

The first thing I did was download the App. I hadn’t done it before because it was limited to a few locations,

but now it’s all over Canada. I could see immediately that many brands of yogurt are all marked down 50 percent.

Users pay for the food using the App, and then pick it up at a marked location in the store. There is no need for you

to worry about them actually being bad.

It makes sense for retailers to get behind this App because it offers a win-win situation for everyone involved.

Flashfood sells 75% of the products made available through its App while saving consumers an average of 50% on

those grocery items, and it has 300,000 active users right now. That number is expected to grow naturally as

Flashfood partners with more grocers.

“As a food retailer, we are in the business of providing food, not wasting it. The Flashfood program allows us

to provide our customers with a convenient and environmentally sustainable ( 可持续的 ) way to purchase food.

Loblaw sells 77% of the items it puts on Flashfood, moving an average of ＄800 to ＄1,000 worth of goods weekly

at each of its largest stores,” said Gord Chem, senior VP with Loblaw’s Real Canadian Superstores.

I love looking for discount deals at the grocery store and always keep an eye out for the hot pink clearance

stickers. But it’s always random, and I never know what I’m going to get from week to week. The appeal of

Flashfood is that I can see what’s available, pre-purchase it, and leave it off my shopping list.

12. What can we know about the food on the Flashfood?

A. It’s delivered directly to the customers. B. Much of it is charged at half the price.

C. Users can pay for it in the marked store. D. It’ll be a month away before it goes bad.

13. According to Gord Chem, the Flashfood is ________.

A. beneficial B. popular C. creative D. reliable

14. How is the advantage of Flashfood introduced in the last paragraph?

A. By listing some examples. B. By making a comparison.

C. By explaining the cause. D. By introducing the result.

15. What is the main idea of the text?

A. Customers can buy much cheaper food on a recent app.

B. A win-win situation has been set for Canadians involved.

C. Canadians have a smart approach to reducing food waste.

细节理解题。从第二段第三句 I could see immediately that many brands of yogurt are all marked down 50

percent.可知，我可以立刻看到许多品牌的酸奶都降价了 50%。由此可知，Flashfood 上许多品牌的食物都标

价打五折。故选 B。

食品进行打折售卖，从而有效地减少了食物浪费。比较四个选项，C项最能概括本文大意。故选 C。

【点睛】主旨大意题主要考查学生把握全文主题和理解中心思想的能力。在解答这类题目时，一般采用通

篇略读法，即对全文通篇速读，舍弃无关紧要的细节，全力捕捉全文的中心思想。重点关注首尾段和其他

段落的首尾句。

（2）2020 届河北衡水中学高考延期提分专版•英语（一）之 D篇

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 also could 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-centimeter prototype one clear December night in Stanford，California. The generator

produced up to about 25 milliwatts of power per square meter of 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 meter. 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 materials 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. ”

12. 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.

13. 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.

14. 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.

15. 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
