1 . There is hot, and then there is hot! Extreme heat is a period of high heat and humidity with temperatures above 90 degrees Fahrenheit for at least two to three days. Extreme heat is responsible for the highest number of annual deaths among all weather-related hazards (危害).

It’s not your imagination. Summers have been getting hotter and hotter with extreme heatwaves occurring earlier and more frequently. But why is this happening and can we better predict heatwaves in advance to give people time to prepare?

“Climate change is here and it’s already been changing human behavior and causing significant influence in the society. As global temperatures rise, historically excessive (过高的) temperatures are more likely to occur.” says Craig Ramseyer, an assistant professor who studies climate modeling in the department of geography at Virginia Tech.

Ramseyer says heatwaves are the most concerning because of the lack of attention they normally receive. “Hurricanes, tornadoes, and flash floods drive more media attention because of the natural attraction with the visual impact of those types of hazards. However, heat does not tend to be as attractive and it becomes very difficult to communicate the danger to the public,” said Ramseyer. “Around the world, more deaths occur due to extreme heat than from hurricanes, flooding, and drought combined. It impacts the most helpless of our citizens who do not have enough access to air conditioning, water, and other important resources.”

Since the Earth is running warmer than it used to, Ramseyer says that when these heatwave-related weather patterns take place, it results in higher extreme temperatures than we used to experience 30 years ago.

“As a global community, we need to decrease carbon emissions as soon as possible. We have rapidly developing technologies that are going to help advance the process, but the faster the better, there is no time to waste.”

2 . The San Diego County Water Authority has an unusual plan to use the city’s San Vicente Reservoir(水库)to store solar power. The project could help unlock America’s clean energy future.

Perhaps ten years from now, large underground pipes will connect the lake to a new reservoir built about 1100 feet higher. When the sun is high in the sky, California’s rich solar power will pump (泵水) water into that upper reservoir. When the sun goes down, the force of water would produce 500 megawatts (百万千瓦)of electricity for up to eight hours. “It’s a water battery!” says Neena Kuzmich, director of engineering for the water authority.

The technology that San Diego puts forward is already in use at more than 40 sites in the US. Some of them were built during the 1970s to store electricity produced by nuclear power plants. Now, the need to store power from renewable sources is bringing this old technology back.

Water batteries have many competitors, when it comes to storing energy. However, they have their own advantages. Water batteries are a proven way to store large amounts of power. The San Vicente project would store about as much electricity as the batteries in 50, 000 of Tesla’s Model 3 cars. They also don’t require hard-to-find battery materials. The biggest problem with them is that it is hard to find places to build them. They need a great deal of water, land to build two reservoirs and permission to damage the landscape.

Kelly Catlett, director of an environmental organization, says, “We won’t support projects that build new damns on rivers and damage ecosystems. But San Diego’s plan looks like something different, because it uses an existing reservoir and doesn’t damage any streams.”

B．They can store renewable sources.

C．The battery materials are easy to get.

D．The technology applied is a new breakthrough.

3. What is the biggest challenge for water batteries?

A．Damage caused to nature.	B．The shortage of solar power.
C．Limited ability to store energy.	D．Proper places for construction.

4. What is Kelly Catlett’s attitude towards the project?

A．Unconcerned.

B．Worried.

C．Supportive.

D．Doubtful.

8 . If you live near a deep forest, you might have come across some wildlife animals hiding in your backyard, but nothing beats the surprise this woman got when she found three baby deer hiding in her house to wait out the storm.

The woman then posted several photos of the baby deer taking refuge (避难) in one of her rooms on her Imgur account “Amscolie”. She wrote that it was a very stormy day and a rainstorm was coming so she left her back door open just in case some animals wanted to take refuge in her house. In the meantime, she went out in the storm to check whether there were any animals that were stuck in the bad weather, especially a number of deer. However, she could not find any of them so she went back to her home.

Surprisingly, she found that the deer had already made their way inside her house!

Like many other animals, deer too can predict stormy weather and know when it is best to find a shelter from the dangerous weather. As the back door was opened, she did not notice when the deer entered her house. The three lovely baby deer made their way inside but there was no sight of their parents. The woman did try to find if there was any deer nearby her house but to no avail. The woman thought that the baby deer might have lost their parents so she welcomed them with open arms.

“I raise orphaned (孤儿的) wildlife. Recently, the back door was open as a storm was coming. The deer were nowhere to be found. I went inside, only to see them next to an end table in the living room. I told them they could sleep in the house for the night because the weather was going to be terrible,” the woman wrote on Little Things. com.
