Ausubel of Rockefeller University in New York, US. says the key renewable energy sources, including sun, wind and biofuels, would all require vast     1     of land if developed up to large scale production¹ – unlike nuclear power. That land would be far better left alone², he says. Renewables look attractive when they are quite     2    . But if we start producing renewable energy on a large scale, the fallout is going to be horrible. Instead, Ausubel argues     3     renewed development of nuclear.

     Ausubel draws his conclusions by analysing the amount of energy renewables, natural gas and nuclear can produce in terms of power per square metre of land used³. Moreover, he claims that as renewable energy use increases, this measure of efficiency⁴ will     4     as the best land for wind, biofuels, and solar power gets used up.

    Using biofuels to obtain the     5     amount of energy as a 1000 megawatt nuclear power plant would require 2500 square kilometres of farm     6    , Ausubel says. "We should be sparing land for nature⁵, not using it as pasture for cars and trucks," he adds.

     Solar power is much more efficient than biofuel in terms of the area of land     7    , but it would still require 150 square kilometres of photovoltaic cells to     8     the energy production of the 1000 MW nuclear plant. In another example, he says meeting the 2005 US electricity demand via wind power alone would need 780,000 square kilometres, an area the size of Texas.

     However, several experts are highly critical     9     Ausubel’s conclusions. John Turner of the US government’s National Renewable Energy Laboratory says that     10     the US got all of its power from solar energy, it would still need less than half the amount of land that has been paved over for highways. Further, it need not     11     additional land. The US could get a quarter of its energy just from covering rooftops of     12     buildings, he says.

     According to Turner, the same "dual use" also applies to wind power⁶. "The footprint for wind⁷ is only 5% of the land that it     13    . Farmers can still farm the land that the turbines are on⁸. Turner says looking solely at land use is an oversimplification of the     14    . "I’m not sure I’d want to build one of these nuclear plants in Afghanistan⁹, but we could     15     put in wind and solar power," he adds.

There was great excitement on the planet of Venus(金星) this week. For the first time Venusian scientists managed to land a satellite on the planet Earth, and it has been sending back signals as well as photographs ever since.

The satellite was directed into an area known as Manhattan (named after the great Venusian astronomer Prof. Manhattan, who first discovered it with his telescope 20000 light years ago).

Because of excellent weather conditions and extremely strong signals, Venusian scientists were able to get valuable information as to feasibility (可行性) of a manned flying saucer (碟) landing on Earth. A press conference was held at the Venus Institute of Technology.

“We have come to the conclusion, based on last week’s satellite landing,” Prof. Zog said, “that there is no life on Earth.”

“How do you know this?” the science reporter of the Venus Evening Star asked.

“For one thing, Earth’s surface in the area of Manhattan is made up of solid concrete and nothing can grow there. For another, the atmosphere is filled with carbon monoxide (一氧化碳) and other deadly gases and nobody could possibly breathe this air and survive.”

“What does this mean as far as our flying saucer program is concerned?”

“We shall have to take our own oxygen with us, which means a much heavier flying saucer than originally planned.”

“Are there any other dangers that you discovered in your studies?”

“Take a look at this photo. You see this dark black cloud hovering(盘旋) over the surface of Earth? We don’t know what it is made of, but it could give us a lot of trouble and we shall have further tests before we send a Venus Being there.”

“Over here you will notice what seems to be a river, but the satellite findings indicates it is polluted and the water is unfit to drink. This means we shall have to carry our own water, which will add even greater weight to the saucer.”

“If all you say is true, won’t this set back the flying saucer program several years?”

“Yes, but we shall continue as soon as the Grubstart gives us the added funds.” Prof. Zog replied.

During the week of great excitement the Venusian scientists succeeded in getting important information as to ____.

A. the feasibility of landing a satellite on Earth

B. the possibility of making a first-rate flying saucer

C. the feasibility of sending a Venus Being to Earth

D. the possibility of directing a flying saucer into Manhattan

According to Prof. Zog, the Venusians will have to take their own oxygen with them when they carry out their flying saucer program because ____.

A. they need it in their way to the planet of Earth

B. the Earth’s atmosphere is filled with deadly gases

C. there is a low level of oxygen for Venusians

D. there is no air on the planet of Earth

The “dark black cloud” on the photo refers to ____.

A. the polluted air hovering over the surface of Earth

B. the mass of tiny drops of water floating above Earth

C. the mass of small things moving through the air

D. the dark clouds gathering before a storm breaks

The author wishes to call our attention to the fact that ____.

A. that modern man has polluted his environment to such an extend that he might destroy himself if he went on like this

B. that there is a point in spending billions to land a flying saucer on Earth

C. that pollution has become so serous a problem on Earth that even Venusians find life there unbearable.

D. that it is difficult if not altogether impossible, to land a manned flying saucer on Earth.

For Americans, a mosquito bite is an itchy(使人发痒的) bother, but for many in Africa, a tiny bite can be deadly. One million people die each year of malaria, a disease spread by infected mosquitoes. Most of these people live in Africa, and are under age 5.

Malaria can be prevented and treated. However, many African nations don’t have the funds to fight it. Nothing but Nets (NBN) hopes to change that. The United Nations Foundation created the campaign in 2006. The mission: Squash(压制) malaria by covering sleeping areas with nets. Hanging bed nets treated with insecticide(杀虫剂) is the simplest way to stop mosquitoes from biting at night. The chemical lasts four to five years. For $10, anyone can send a net to Africa and help save a life.

So far, NBN has raised $19 million and delivered 700,000 nets to seven countries. Families are taught how to use the nets. Kids also get vaccines(疫苗) and vitamins. “Women line up for miles to get these interventions(干预措施) for their kids,” says NBN director Elizabeth McKee Gore. “They understand the importance.” So do kids in this country. “They get so excited thinking of ways to raise money,” says NBN spokesperson and basketball star Ruth Riley.

NBN’s biggest fund-raiser is Katherine Commale, 7. She’s been spreading the buzz(嗡嗡声) about bed nets for the past two years. To show how they work, she and her brother made a picture. “We teach that bed nets can save lives,” she told TFK.

Katherine has raised $42,000 for NBN. “She just wants those who need a net to have one,” says her mom, Lynda. “It’s pretty simple to her.” To find out how you can help, visit nothingbutnets.net.

Governments and health officials around the world continued to take steps Tuesday against the outbreak of swine flu that has killed scores of people in Mexico and spread to the U.S., Europe and possibly Asia.

By early Tuesday, the swine flu outbreak in Mexico had caused in 152 deaths and more than 1,600 illnesses. So far, at least 113 cases have been proved worldwide, including 64 in the United States; six in Canada; 11 in New Zealand and two each in Spain the United Kingdom and Israel. None has yet resulted in death.

The World Health Organization on Monday raised its alert level from three to four on its six-level scale. The move means the U.N. agency has determined that the virus can transmit

from human to human.

"In this age of global travel, where people move around in airplanes so quickly, there is no region to which this virus could not spread," said Fukuda, assistant director-general of the WHO.

Governments around the world struggled to prevent further outbreak. Some, like China and Russia, banned pork imports from the United States and Mexico. U.S. President Barack Obama said the outbreak was a cause for concern, not for alarm. The government urged travelers to avoid non-essential travel to Mexico.

The latest WHO report listed only seven proved swine flu deaths in Mexico but it was not clear why there was the discrepency.

Mexico City has closed all schools until at least May 6 to help curb(control) the spread of swine flu and ordered 35,00 public venues to close or serve only takeaway meals. In addition, bars, clubs, movie theaters, pool halls, gyms, sport centers and convention halls have been told to close until May 5. Armed police officers are also guarding hospitals in Mexico City while roads and schools in the city of 20 million people are deserted. Officials also have talked about shutting down the bus and subway systems.

57.How many people were found catching swine flu in Spain?

A. 2.                     B. 11.             C. 6.                     D. 64.

58.When learning the outbreak of swine flu, the WHO was ____.

A. calm          B. nervous      C. shocked      D. careful

59. Fukuda’s words suggest that _____.

A. he likes travel by air

B. global travel hasn’t been affected

C.this virus can spread quickly because of global travel

D. planes must be forbidden to take to prevent swine flu

60.The last paragraph mainly tells us _____.

A. Mexico has taken measures to control swine flu

B. Mexico City is too dangerous to live in

C. the normal life in Mexico has been changed

D. people in Mexico are badly in need of help
