The Internet has changed the world we live in...

The Internet has changed the world we live in dramatically, so that in some ways it is unrecognizable from the place we lived in twenty years ago. Communications have been revolutionized. Not only have cell phones found their way into most people’s pockets or purses, but they are also used for next messaging and as cameras. Long distance phone calls have been replaced by e-mail and video conferencing. Communications, person to person or company to company, have turned into a fast-paced exchange with instant response. In fact, it has become more convenient and efficient.

The other kind of communication the Internet provides is information. School children and medical researchers alike will tell you that they could not work without the Internet and its ability to connect them to any number of websites and databases of information. Many people do their banking on-line. Others plan a trip and book a flight for themselves. People do their own stock  trading through the Net. Sports fans follow scores and statistics on websites. Political junkies(政治狂) gather campaign statements and debate topics, even between elections. And almost everyone who owns a computer and has Internet access has bought at least one item on-line. No wonder some young people can not imagine what life was like before the Internet.

Recently, we have already shown that climate change has led to a dramatic increase in storm surge risk in New York City, making devastating events like Hurricane Sandy more likely.

What can we say about the role of climate change in the unprecedented disaster that is unfolding in Houston with Hurricane Harvey? There are certain climate change-related factors that we can, with great confidence, say worsened the flooding.

Sea Level rise attributable to climate change-some of which is due to coastal subsidence(下沉) caused by human disturbance such as oil drilling-is more than half a foot(15cm) over the past few decades. That means the storm surge was half a foot higher than it would have been just decades ago, meaning far more flooding and destruction.

In addition to that, sea surface temperatures in the region have risen about 0.5℃(close to 1F) over the past few decades from roughly 30℃(86F) to 30.5℃(87F), which contributed to the very warm sea surface temperatures(30.5-31℃, or 87-88F). There is a simple thermodynamic(热力学的) relationship known as the Clausius-Clapeyron equation that tells us there is a roughly 3% increase in average atmospheric moisture content for each 0.5℃ of warming. Sea surface temperatures in the area where Harvey intensified were 0.5-1℃ warmer than current-day average temperatures, which translates to 1-1.5℃ warmer than “average” temperatures a few decades ago. That means 3-5% more moisture(水分) in the atmosphere. That large amount of moisture creates the potential for much greater rainfalls and greater flooding. The combination of coastal flooding and heavy rainfall is responsible for the devastating flooding that Houston is experiencing.

Not only are the surface waters of the Gulf of Mexico unusually warm right now, but there is a deep layer of warm water that Harvey was able to feed upon when it intensified at near record pace as it neared the coast. Human-caused warming is penetrating down into the ocean. It’s creating deeper layers of warm water in the Gulf and elsewhere. Harvey was almost certainly more intense than it would have been in the absence of human-caused warming, which means stronger winds, more wind damage and a larger storm surge.

Finally, the more tenuous but potentially relevant climate factors: part of what has made Harvey such a devastating(毁灭性的) storm is the way it has stalled near the coast. It continues to strike Houston and surrounding regions with a seemingly endless flood, which will likely top out at nearly 4ft(1.22m) of rainfall over a days-long period before it is done. The stalling is due to very weak prevailing winds, which are failing to steer the storm off to sea, allowing it to spin around and wobble back and forth. This pattern, in turn, is associated with a greatly expanded subtropical high pressure system over much of the US at the moment, with the jet stream pushed well to the north. This pattern of subtropical expansion is predicted in model simulations of human-caused climate change. More tenuous(微弱的), but possibly relevant still, is the fact that very persistent, nearly “stationary” summer weather patterns of this sort, where weather anomalies(both high-pressure dry hot regions and low-pressure stormy/rainy regions) stay locked in place for many days at a time, appears to be favoured by human-caused climate change.

In conclusion, while we cannot say climate change “caused” Hurricane Harvey, what we can say is that it exacerbated several characteristics of the storm in a way that greatly increased the risk of damage and loss of life. Climate change worsened the impact of Hurricane Harvey.

1.What’s the main purpose of writing the passage?

A. To offer tips on climate change.

B. To advocate paying more attention to current climate change urgently.

C. To share experiences on avoiding climate change.

D. To criticize human-caused climate change.

2.The underlined word “intensified” in Paragraph 4 probably means ________.

A. worsened　　 B. caused

C. favoured　　 D. increased

3.What is the best title for the passage?

A. Climate change made Hurricane Harvey more deadly

B. Sea level rise sea and surface temperatures changed Hurricane Harvey

C. Hurricane Harvey and its characteristics

D. The climate change-related factors and human-caused warming

4.Which of the following shows the development of ideas in this passage?

The Internet has opened up a whole new online world for us to meet, chat and go where we’ve never been before.

But just as in face-to-face communication, there are some rules of behavior that should be followed when on line. 　 1. 　 Imagine how you’d feel if you were in the other person’s shoes.

For anything you’re about to send: ask yourself, “Would I say this to the person’s face?” If the answer is no, rewrite and reread. 2.

If someone in the chat room is rude to you, your instinct (本能) is to fire back in the same manner. But try not to do so. 　 3.　 If it was caused by a disagreement with another member, try to fix the situation by politely discussing it. Remember to respect the beliefs and opinions of others in the chat room.

4.　 Offer advice when asked by newcomers, as they may not be sure what to do or how to communicate. When someone makes a mistake, whether it’s a stupid question or an unnecessarily long answer, be kind about it. If it’s a small mistake, you may not need to say anything. Even if you feel strongly about it, think twice before saying anything. Having good manners yourself doesn’t give you a license to correct everyone else. 5.　　 At the same time, if you find you are wrong, be sure to correct yourself and apologize to those that you have offended(冒犯).

It is not polite to ask others personal questions such as their age, sex and marital status(婚姻地位). Unless you know the person very well, and you are both comfortable with sharing personal information, don’t ask such questions.

A. It’s natural that there are some people who speak rudely or make mistakes online.

B. Repeat the process(过程) till you feel sure that you’d feel comfortable saying the words to the person’s face.

C. Everyone was new to the network once.

D. The basic rule is simple: treat others in the same way you would want to be treated.

E. When you send short messages to a person online, you must say something beautiful to hear.

F. You should either ignore the person, or use your chat software to block their messages.

G. If you do decide to tell someone about a mistake, point it out politely.

In the past hundred years, the world’s attitude toward whales has changed a lot. The animals are no longer seen as frightening creatures and worldwide protection efforts have reduced whale hunting. Through careful observation, scientists have shown that whales are generally peaceful, playful creatures, and that they have a high level of intelligence.

But even now, some behaviour of whales is still a mystery. A lot of information gathered by whale researchers has raised new puzzles about the animals. Whales’ communication is particularly difficult to understand. Male humpbacks (also known as bulls) give off a sequence (一连串) of low moans（呻吟）, high screams and clicking noises. These noises are sometimes combined in songs that last as long as 30 minutes. And in a particular region, every male will sing the same song, making small changes every once in a while so that it evolves (逐渐形成) into a completely different song over time.

This behavior seems to be related to reproduction. During the mating (交配) season, a male humpback starts the long song sequence, stopping only to join a passing female whale (also known as a cow). Eventually, the bull and the cow may dive deep into the ocean, probably to mate. Male humpbacks’ songs are similar to what birds display to attract mates (配偶), except that the sound carries over many miles, attracting some other male humpbacks in the area. It’s very odd that a male would call his own competition to him, unless he actually wanted to test his strength against others. Some whale researchers believe that the songs are actually acoustic (听觉的) contests of strength.

1.What can we infer from the first paragraph?

A. We used to have wrong ideas about whales.

B. Whales are in danger of dying out today.

C. Whales have always been considered as fierce creatures.

D. Whales are only protected in some parts of the world.

2.We can learn from the second paragraph that 　　　　 .

A. male whales and female whales both sing songs

B. people can’t fully understand whales’ communication

C. people only understand the songs of male whales

D. the songs of male whales never change

3.The last paragraph suggests that male humpbacks sing songs most probably to 　　　　 .

A. find their own family members

B. work together with others to hunt

C. compete against other male humpbacks

D. frighten away other male humpbacks
