Many people like the feeling of the gentle wind in spring. Many like to see the falling leaves dancing in the wind in autumn. But sometimes, when the wind becomes a storm, it can be very destructive(具有破坏性的).
A series of such storms struck the US last month and caused very serious damage and human pain.
Every year, major storms cause many problems around the world. There is nothing people can do to stop these powerful forces of nature. But new techniques are helping scientists to predict(预测) how, when, and where big storms will happen. The more exact scientists’ warnings are, the better people can prepare for the storms.
Predictions are improving. “We’re gotten better over the years, especially the last few years,” says Phil Klotzbach, a scientist at an American university. How is a storm formed? Even if scientists know where a storm will happen, winds can suddenly change, carrying the storm to a new direction. “For a hurricane to happen, conditions have to be just right, ” Klotzbach says.
First, the ocean water needs to be warm enough so that it evaporates and rises into the air. As it rises, the vapor（水蒸气）cools and turns back into liquid. This process gives off heat. This produces energy like an engine that causes winds to increase. It drives the formation(形成) of a hurricane.
If wind speeds reach 40 miles per hour, the system is called a “tropical storm”(热带风暴), and it gets a name. At 75 miles per hour, it becomes a hurricane.
H
urricanes that hit the US start when a thunderstorm forms off the coast of Africa. Storms also develop over tropical waters in other parts of the world.
On average, 60 or 70 storms form off Africa every year. About 10 of them get names. There are usually abo
ut six hurricanes. Two tend to be very big, with winds of 115 miles per hour or higher.
The hurricane season lasts from June to November. Ninety percent of all hurricanes hit in August, September, and October.

In June, an isolated tribe known to semi-permanently reside in Peru emerged from the forest on the neighboring Envira River in Brazil to make contact with the outside world. Such contact happens surprisingly often, but it is usually brief. “This is unique in that they’ve chosen to stay,” says Chris Fagan, director of the nongovernmental group Upper Amazon Conservancy.
Reportedly under threat from illegal loggers, a few dozen tribespeople remain near the village where they first emerged. They are under the supervision of FUNAI, Brazil’s agency for Indian affairs. During many past contact events, members of the isolated groups died after encountering modern diseases for the first time. But experts hope the group that emerged in June will fare (进展) better because members have stayed long enough to receive medical care. There’s still concern that other members of the group’s tribe may have remained in the forest, vulnerable to disease and unreachable by medical personnel.
“The worst-case scenario (方案) is that some people get sick and go back to the original tribe,” says University of Missouri anthropologist Robert Walker, who studies Amazonian populations. “That’s the huge worry.”
Walker, who studies satellite imagery (卫星图) of the rainforest for evidence of isolated villages, says four or five such nomadic hunter-gatherer groups live in the Envira River watershed, though he estimates between 50 and 100 isolated indigenous (土生土长的) groups live in Greater Amazonia. These groups often make fleeting (短暂的) contact to steal tools from frontier towns, but most, he says, remain isolated out of fear. “Some of these folks’ ancestors have been massacred,” he says. “They were contacted, violently, in the past.”
Now, with illegal loggers and drug smugglers invading land reserves established to protect the tribespeople’s way of life, these isolated groups are feeling pressured out of their homes. And although activist groups and government anthropologists train locals to temporarily leave the area when isolated tribes arrive as a way to prevent the spread of disease, lack of official protocols (协议), consistent enforcement and regular compensation for villagers often make it an ineffective solution.
These tribespeople “have a right to continue their lifestyle as long as they want to,” Fagan says. “There are land reserves set up to allow them to do that, and those reserves are failing.”Where do the tribespeople who make contact with the outside world live?
| A．In the US. | B．In Brazil. |
| C．In Peru. | D．In Cuba. |

A Swiss airplane powered only by energy from the sun left from Abu Dhabi early on March 9. Its creators hope the plane will make the first around-the-world journey without any fuel.
The plane is called Solar Impulse 2. It has one seat and is made from carbon fiber. The plane weighs only as much as a car but its wings are wider than a Boeing 747. The plane’s wings stretch 72 meters across.
Those wings include 17,000 solar units, or cells, that capture the sun’s energy. The energy allows the plane to fly day and night.
Two Swiss scientists built the plane. Bertrand Piccard is also an explorer who made the first non-stop flight around the world in a balloon. Borschberg is an engineer and trained fighter pilot.
The scientists say they are not trying to change the airplane industry. Instead, they want to show that new energy sources and technologies can achieve what some say is impossible.
“We want to show we can fly day and night in an aircraft without a drop of fuel,” Mr. Piccard said.
Some parts of the trip will require the pilots to be in the tiny plane for five to six days and nights in a row. So it is good that the pilot’s seat is also a toilet.
The plane’s route begins in the United Arab Emirates. The pilots also plan stops in Oman, India, and China. They will cross the Pacific Ocean, stop in the United States, and continue over southern Europe or North Africa. They plan to arrive back in the United Arab Emirates in late July or early August.Which of the following is the plan stops of the tour made by the solar-powered plane?
| A．Abu Dhabi---Oman---China---the United States--- southern Europe ---the United Arab Emirates |
| B．the United Arab Emirates--Oman--- India---the United States--- North Africa--- Abu Dhabi |
| C．the United Arab Emirates--Oman--- India ---China---southern Europe --- Abu Dhabi |
| D．Abu Dhabi--Oman--- India ---China---the United States--- the United Arab Emirates |
What can be inferred from the passage?
| A．The plane’s wings include 17,000 solar units, or cells, that capture the sun’s energy. |
| B．The plane weighs only as much as a car but its wings are narrower than a Boeing 747. |
| C．Bertrand Piccard is one of the co-builders of the plane. |
| D．The scientists are trying to change the airplane industry. |
What’s the best title of the passage?
| A．Solar Powered Plane Starts World Tour |
| B．A Plane Powered By Solar Energy |
| C．A Plane’s Route Begins in the United Arab Emirates |
| D．A Tour Around the World |

It’s reported that powerful Cyclone Pam has impacted at least half the population of Vanuatu, which is a South Pacific island nation.
“Vanuatu is used to disasters but the indications are that Cyclone Pam has caused unprecedented damages,” said President Baldwin Lonsdale in a press release.
The leader of the island nation noted that following a direct hit from the Category 5 storm on Friday, at least two deaths have been confirmed and over 30 injured people are being treated in the Central Hospital in the capital, Port Vila where many people are now homeless and torrential rain has led to severe flooding. He also said bridges which link the capital with the rest of the island have been destroyed.
Mr. Lonsdale made his appeal from Sendai, Japan, where he has been attending since Sunday the Third UN World Conference on Disaster Risk Reduction. The Conference has drawn thousands of Government and civil society delegations to craft a new framework for managing disaster risk which will reduce mortality and curb economic losses.
The country is already threatened by coastal erosion and rising sea levels in addition to five active volcanoes and earthquakes. "This is why I am attending this Conference and why Vanuatu wants to see a strong new framework on disaster risk reduction which will support us in tackling the drivers of disaster risk such as climate change."
Meanwhile, the UN Children’s Fund (UNICEF) reports that it is estimated that at least half the population of Vanuatu has been affected by cyclone Pam. Of these, at least 54,000 are children.
Many homes in Vanuatu have likely been destroyed as they are built with natural and local materials such as thatched and corrugated roofs that are vulnerable to strong winds and floods.
Other Pacific Island countries have been severely impacted as well, including the Solomon Islands, Tuvalu and Kiribati.
A UN Disaster Assessment and Coordination (UNDAC) team was expected arrive in Port Vila late Saturday. OCHA was also expected to deploy three staff with information management, public information and humanitarian coordination as well.
From what President Baldwin Lonsdale said in the second paragraph, we can know that ______.
| A．Vanuatu is a beautiful South Pacific island nation. |
| B．Vanuatu wants to see a strong new framework on disaster risk reduction. |
| C．Vanuatu suffers from natural disasters a lot. |
| D．Vanuatu will have a bright future on tourism. |
According to the passage, which of the following is TRUE?
| A．At least 3 deaths have been confirmed and over twenty people injured. |
| B．Port Vila is the capital of Vanuatu. |
| C．The country is not yet threatened by coastal erosion and rising sea levels. |
| D．The UN Children’s Fund (UNICEF) reports that half the children has been affected by cyclone Pam. |
What can we know from the last three paragraphs?
| A．Some international rescue teams are being under way. |
| B．Four other Pacific Island countries have been severely impacted by Cyclone Pam except Vanuatu. |
| C．Many houses in Vanuatu are still strong enough for people to live in. |
| D．A UN team was expected arrive in Port Vila late Sunday. |
Where was the Third UN World Conference on Disaster Risk Reduction being held?
A. In Vanuatu. B. In the USA.
C. In China. D. In Japan.

THE TRIP OF A LIFETIME
In June 1971, Helene Hanff travelled to London and visited the site of Marks & Co, the bookshop that had been dear to her for 20 years. While Hanff was very happy to finally step foot on British soil the visit carried with it a sad irony (讽刺), which she explained in a 1980 television interview with Dick Cavett: “It was very sad,” she said. “It was the bookstore manager Frank Doel’s death that made me want to write the story of our correspondence and when a publisher bought it, I went to London on the proceeds of the sale.”
Hanff spent the early part of her career trying to make a name for herself as a playwright. London-based writer Monica Porter, who met her in the 1980s, says that Hanff considered herself a “failed playwright” and that her 1961 book Underfoot in Show Business was an account of her failure to get her plays produced. A decade after 84, Charing Cross Road was published, James Roose-Evans adapted the book for the stage and the play was a West End hit.
It had a 16-month run and Hanff finally got to taste stage success, albeit (虽然；即使) in a circuitous (迂回的) way. In a piece that Porter wrote for the British weekly newspaper, The Stage, she says Hanff was led on stage at the end of the opening night performance to thunderous applause. “To get a standing ovation(热烈的鼓掌) like that, taking curtain calls before an enthusiastic audience, was something she must often have dreamt about,” Porter wrote.
The stage adaptation opened in the US a year later, but never lived up to its West End success. This was to Hanff’s great relief. According to Porter, she once recounted: “Being a celebrity for a week in London had been the most fun I’d had in my life, and wonderful for the ego (自我) - but only because I’d known I was coming home at the end of it, home to the quiet, orderly, solitary(独立的), unglamorous life I was made for.”
However, her peace was not to last: Hollywood came calling. The 1987 film of 84 Charing Cross Road, produced by Mel Brooks, won several awards.
Anne Bancroft starred as Hanff. Doel was played by Anthony Hopkins. Hanff died in New York in 1997 from diabetes-related complications. Today, the Marks & Co building is a restaurant with a plaque on its street frontage that commemorates(纪念) the author that made the site so famous. And Hanff’s unlikely bestseller remains in print.What made Helene Hanff want to write the story of their correspondence?

Many people rely on a cup of coffee or two to wake them up in the morning or pick them up during the working day, but now a chemist has come up with a speedy alternative to crafting a cup of coffee.
U.S. biochemist Ben Yu has created `Sprayable Energy,` which claims to be the world`s first caffeine - based topical energy spray.He said tired workers can spray a `shot` of caffeine onto their skin without experiencing a strong buzz, loading up on unnecessary calories or being stuck with a nasty aftertaste like they might get from drinking energy drinks or coffee.
The patent-pending caffeine spray is an odourless liquid that is absorbed through the skin and distributed through the body over a number of hours to deliver a caffeine hit that apparently lasts longer than guzzling a cup of coffee.
Each small aluminum bottle of Sprayable Energy contains around 160 sprays - the equivalent amount of caffeine to 40 cups of coffee and the creators say it is a much cheaper way of getting a caffeine fix than popping to a cafe.The only active ingredient in the spray is caffeine, which can naturally enter the human body through the skin by passing through cell membranes as it is very similar to nicotine in structure.Each spritz of Sprayable Energy contains around a quarter of the amount of caffeine found in a cup of coffee, but apparently has the same effect as a full cup.
The website said: `The reason for this is our product not being ingested, isn`t almost entirely metabolised（新陈代谢） by the liver before entering your system and becoming available to your body.`
`Thus, a smaller amount of caffeine can have just the same effect as a very large amount of caffeine ingested through an energy drink or cup of coffee.`c`s website recommends that users apply the spray in places where they normally spritz perfume, such as the neck or wrists, but warns users not to exceed 20 sprays a day.
It claims that after spraying the product on the skin, users will feel `awake and focused without being over-stimulated,` which is common with coffee and energy drinks.What can we learn about Sprayable Energy from the passage ?_______.
| A．A bottle of Sprayable Energyis cheaper than 40 cups of coffee. . |
| B．Sprayable Energy lets users not worry about taking in unnecessary calories.. |
| C．Sprayable Energy can be used at least 20 sprays a day |
| D．The caffeine spray is a colorless liquid that is absorbed through the skin.. |
What does the fifth paragraph mainly tell us ?____
A,Sprayable Energy is taken by mouth...
B.Before Sprayable Energy is absorbed by body, the liver entirely metabolizes it
C.How Sprayable Energy acts on user’s body and how users use the product.
D.Sprayable Energy is convenient but expensive.We can conclude from the passage that ____
| A．Sprayable Energy can not be permitted to be used by people now. |
| B．Sprayable Energy has not already gone into mass production |
| C．each spritz of Sprayable Energy has the same effect as a full cup of coffee |
| D．Sprayable Energy is well received by flagging workers. |
The writer’s attitude towards Sprayable Energy ____
| A．negative. |
| B．positive |
| C．uncertain |
| D．indifferent |
