【题目】Why Radio Stations Always Start With a "K" or "W"

It seems that whenever you switch on the radio in the morning all you hear is "Time to wake up with K98.3," or "WBLS will be right back after this commercial break".1The majority of radio stations start with the letter "K" or "W".

All radio stations have a four-letter identification code(代码). The hosts of the show typically come up with a more catchy(易记的)station name than just the four letters, but you still hear it sprinkled in with their morning announcements and other advertisements.2In 1912, several countries attended a conference to discuss international radiotelegraphs. One of the things that came out of that meeting was the assignment(分配)or specific letters to identify each country's radio and television signals.3

The letters "N" and "A" were given to military stations, but "K" and "W" were assigned out for commercial use.4And stations west of the Mississippi started with "K".

5Sometimes they represent the networks that own the radio station for example, WABC, KCBS, and WTBS. Sometimes it's the actual station number, like in KTWO or KFOR. And other times it's an acronym(缩写)such as WTTW for "Windows to the World." But the station that takes home the prize for the best four-letter combination is a sports radio station out of St. Louis that chose the name KRAP.

A. The United States was given the letters W, K, N, and A.

B. The three letters after the "K" Or "W" can mean a few different things.

C. If you listen closely you'll notice that they all have something in common.

D. Radio stations east of the Mississippi River had to start their stations with "W".

E. The two letters you consistently hear date back to when people used to send telegrams.

F. There is some inconsistency since radio stations weren't required to change their name.

G. Try decoding these common acronyms that you probably never knew and figure out what they stand for.

On the behalf of our group, I’d like to give a brief summary of our discussion on the topic “Are Recycling Textbooks a Good Suggestion?” As we know, when high school students graduated from school, their textbooks are throwing away, which are still in good condition. What a great waste it is!

A suggestion has been put forward we should recycle the textbooks. Some students in my group agree with this suggestion. For one thing, recycling textbooks can save a lot of natural resources, what are used to make textbooks. And it can also save plenty of family expenses. For another, in western countries, recycling textbook is very popular and it gives you a good example. But some have different opinions about it, for the content of the textbooks is often renewed. What’s more, it is not proper to make notes in the textbooks. In my opinion, this is a wonderfully idea because this will do good to both the government and the families.

【题目】 This season, the bushfires in Australia have burned more than 12.35 million acres of land. At least 25 people have been killed and 2000 homes destroyed. According to the BBC, this is the most casualties(伤亡) from wildfires in the country since 2009. The University of Sydney estimates that 480 million animals have died in South Wales alone.

Zeke Hausfather, an energy systems analyst and climate researcher at Berkeley Earth, said warmer temperatures and extreme weather have made Australia more susceptible to fires and increased the length of the fire season. “The drier conditions combined with record high temperatures in 2019 created main conditions for the disastrous fires. Australia’s fires were worsened by the combination of those two. 2019 was the perfect storm for being the warmest year on record for Australia and the driest year on record for Australia,” Hausfather added on Friday.

Kevin Trenberth, a senior scientist at the US National Center for Atmospheric Research, said warmer ocean temperatures are also contributed to more variable weather around the world. Trenberth believes that global warming contributed to energy imbalances and hot spots in the oceans, which can create a wave in the atmosphere that locks weather patterns in places, causing longer rain events in Indonesia, for example, and at the same time contributing to drought in Australia. He said that once an area experiences drought conditions for two months or more, it increases the risk of fires catching and spreading. Those changing weather patterns due to global warming make drought events longer.

Climate experts stress that climate change is not the only factor in the severity of wildfires. How land is managed can also impact the amount of fuel available for fires. Practices like controlled burns and other factors can impact the risk to people and property, such as warning systems and the type of development in a given area. Changing those policies has great potential to limit future damage from wildfires along with changes to how fire management resources are dispatched(派遣).

1What do the numbers in paragraph 1 show?

A.The causes of Australian fires.

C.Sensitive to.D.Easy to be protected from.

3What can we infer from Trenberth's research?

A.Global warming is the root cause of the bushfires.

B.Longer dry weather contributes to global warming.

C.Warmer ocean temperatures promote fires spreading.

D.The imbalanced energy leads to the temperature rising.

4What does the author intend to do in the last paragraph?

A.To stress the effects of Australia fires.

B.To show the methods for controlling burns.

C.To predict the seriousness of Australia fires.
