Have you ever heard of an insect called the cicada(蝉)? 1. But they have an interesting internal clock that tells them when to go aboveground.
Every 17 years, billions of the noisy Brood V cicadas(十七年蝉) will swarm(成群出现) to northeastern parts of the US, including New York, Ohio and Pennsylvania. 2.But there are usually a lot less of them compared to the Brood V cicadas.
3. According to Discovery News, these insects started their lives in 1999. And as their 17-year life cycle comes to an end, they go aboveground when their underground homes get warmer 64 degrees Fahrenheit (about 18℃) to be exact.
Then the females will lay hundreds of eggs in trees, and after about four to six weeks, the mother and father cicadas will die. 4.
While they can be kind of annoying, these insects don’t harm humans, but they do make a lot of noise during their time aboveground. 5.
However, since there are so many of the 17-year cicadas, the amount of laid eggs can sometimes harm small trees and bushes. But after this summer, these insects will mostly mind their own business until 2033.
A. That sound is the male cicadas attracting the female cicadas.
B. The cicada insects are common in summer, especially in August and can be found in July as well.
C. There are other kinds of cicadas that come around once a year or every 13 years.
D. The baby cicadas will go underground, and the 17-year cycle will start over again.
E. As a matter of fact, people like to eat them in some cultures.
F. Well, a special kind of these insects live underground in the US for most of their lives.
G. This is what makes Brood V cicadas so special.

Have you ever heard of the Coral Sea? It is home to an amazing variety of turtles, sharks, whales, dolphins, large fish, birds, corals, plants, and many other species. Many of these species are endangered elsewhere in the world, but still survive in the healthy environment of the Coral Sea.
The Coral Sea is a large series of coral reefs located off the northeast coast of Australia. This area is three times larger than Australia’s famous Great Barrier Reef, which the Coral Sea borders.
The Coral Sea is one of the few coral reef environments that have remained largely undamaged by over-fishing, oil and gas exploration and pollution. However, statistics show that coral reefs around the world are disappearing five times faster than rainforests. It is very likely that in the near future the Coral Sea will face the same threats to its existence.
The Australian government is currently looking at options for protecting the Coral Sea but has made no decisions. Environmentalists are pushing for laws to declare the Coral Sea area a marine protected area, which will mean a large “no-take zone” for fishermen, a no-exploration zone for gas and oil companies and a no-dump zone for pollution, possibly making the Coral Sea a marine park larger than any other in the world.
We can write letters to Australian leaders, Australian environmental protection agencies, and Australian friends, to let them know that people worldwide support this protection of the Coral Sea. To lose this last great marine wilderness world would be a loss for the whole world.
1.According to the passage, why should we protect the Coral Sea without any delay?
A. Because the Coral Sea, home to many species, will disappear soon.
B. Because the Coral Sea is rich in natural resources like oil and gas.
C. Because the Coral Sea is three times larger than Great Barrier Reef.
D. Because the Coral Sea will be a marine park larger than any other in the world.
2.Once the Coral Sea area is declared n marine protected area by law, .
A. it will surely become the largest marine park all over the world
B. no one will be allowed to there to have a dose look any more
C. from time to time people can still dump their rubbish around there
D. over-fishing, oil and gas exploration will be banned altogether there
3.What is the attitude of the author towards the protection of the Coral Sea?
A. Objective. B. Favorable.
C. Doubtful. D. Negative.

Have you ever heard of the phrase “we just can’t communicate”? Most people communicate with the ability to read or write well. This might not be the case as you will soon find out.
How many times have you been to the doctor’s office and listened to an educated professional explain something to you that is just unintelligible. These people keep asking you, “Do you understand?” and sometimes out of embarrassment because you don’t want to look like stupid, you tell them. “Yes, I do understand.” This isn’t a good way to communicate, either.
How do we communicate in a positive way to get our points across? Ask the persons you are communicating with if they understand what you just said. In another case, if someone is talking to you, use the statement, “Just to make sure that I understand what you just said” and then repeat back your understanding of their conversation. Sometimes just asking a few simple questions and clarifying your understanding can bring great benefits to any communication.
In some countries like Japan, you might find them reading your body language more than the words you are communicating with. Sometimes just by the way someone stands or reacts to something you said, you can get a valuable insight to what the other person means in this conversation. Don’t forget, however, this could also lead to a misunderstanding. Again if you think someone is communicating with their body language, try not to assume that you know exactly what message they are trying to get across. Always ask them if they understand what you are talking about.
A person is responsible for what he says and to make sure that the other person completely understands the point he is trying to get across. Why not start using some of the simple skills in this article to help with your communication skill? You will start to see the benefits within a short period of time.

2.What does people intend to do when they repeat your conversation?

Have you ever heard the story of the four-minute miles? Many years ago, people believed that it was impossible for a human being to run a mile in less than four minutes until Roger Banister proved it wrong in 1954.
What happens if you put an animal in a pond? Any animal, big or small, will swim its way through. What happens when someone, who doesn’t know how to swim, falls in deep water? They drown. If an animal who has not learnt swimming could escape by swimming, why not you? Because you believe you will drown while the animal doesn’t.

Cucamelons look like baby watermelons and taste like cucumbers mixed with lemon. 1. You can grow them in a pot, plastic bag or directly into a garden. These plants are fast growers and have a maturity of 80 days, which means you can grow them when it starts to get colder, too. 2. You’d have to look online and purchase them. Generally speaking, you can receive them within 7 days.
If you choose to plant them directly into your garden, you can plant them as soon as the chance of frost is gone. 3. You can put wood sticks into the ground for the roots to grow on, or use bamboo sticks as an alternative. After your first season of growing Cucamelons, you’ll notice that the root is very long. You can dig up these roots and store them in a cool, dry place and re-pot them at the start of the next growing season. 4. It will be a big harvest! By the way, you can use Cucamelons in food dishes or in drinks. The thought sounds pretty excellent!
5. Your neighbors might even feel inspired to grow Cucamelons themselves!

G. This will give you ten times as many Cucamelons the next time around!

You may have heard of the American Dream, an ideal that has powered the hopes of Americans for generations.
It began as a belief that the US was a land of opportunity, and that anyone could achieve success through hard work. At times, the dream has referred to home ownership, a good job, retirement security or each generation doing better than the last.
Yet today, this concept seems to have greatly changed. As Time magazine pointed out, quite different from the older generation, many Millennials (the generation born after 1980) redefine(重新定义) the American Dream as “day-to-day control of your life”. They “prize job mobility, flexible schedules, any work that is more interesting than typing, and the ability to travel”, said the magazine.
Home ownership, once the cornerstone of the American Dream, is becoming a smaller priority for this generation. Meanwhile, nearly 40% of them choose travel as part of their dream. And entrepreneurship(创业) is a rising favorite, as nearly 26% of Millennials consider self-employment as part of their dream.
So what has led to this huge change?
Many point fingers at the poor economy. “Modern young Americans seem bound to face a world stamped by ever narrowing opportunity and social stagnation(停滞),”noted The Daily Beast.
“The rate of 16-to 24-year-olds out of school and out of work is unusually high at 15%. Many college graduates have taken jobs that don’t require a degree,” Time reported.
The magazine worries that these difficulties may lead to a lost generation who are “unable to ever truly find their feet on the corporation’s ladder”.
Dan Kadlec, a reporter of Time, sees Millennials as resetting their expectations. “This situation is different for young adults today,” he wrote. “A true American dream has to feel attainable, and many Millennias are feeling they can only attain a day-today lifestyle that suits them.”
1.What’s the passage mainly about?
A. Meaning of American Dream
B. Redefinition of American Dream
C. Value of Achieving American Dream
D. History of Changing American Dream
2.The underlined word “cornerstone” in Paragraph 4 is closest in meaning to “ ”.
A. growth B. balance
C. purpose D. basis
3.According to the passage, what has changed Millennials’ view of the American Dream?
A. A lack of confidence in themselves
B. Fierce competition in the job market
C. The discouraging economy and unemployment
D. Their dissatisfaction with the government
4.Dan Kadlec thinks Millennials’ new definition of the American Dream is ______.
A. understandable B. beautiful
C. worrying D. Positive
