In 1752, three years after two Scotsmen, Alexander Wilson and Thomas Melville, fastened thermometers to kites to record the temperature of clouds, Benjamin Franklin made his famous experiment with a kite, a string, and a key．Franklin hoped to show that nature’s tremendous displays of electricity in lightning were the same thing as the feeble electric sparks scientists of the day were producing in their laboratories．He built a square kite to which he attached an iron wire．He flew the kite with a hemp string(麻线), and near the base of the string he tied a large brass key．The kite rose into a dark thundercloud, where the iron wire picked up electrical charges．Franklin noticed that the strands of the string(绳串)were beginning to stand up with electricity．As rain wet the string, it conducted more electricity．Standing in the shelter of a shed, Franklin cautiously reached out his finger to touch the brass key．A series of sparks jumped from the key to his finger．He thus proved that lightning and electricity are the same．We now know that this experiment was a dangerous one, for Franklin might have been killed by a bolt of lighting．

The ________(discover)of oil on their land made the family rich．

Life on Mars could become a reality and it could happen in your lifetime.

A welcoming planet

Scientists say Earth’s neighbor Mars, a bright red planet about half Earth’s size, is the most likely to support human life. Mars even has frozen water on its surface.

Since the late 1990s, NASA has been exploring Mars using remote-controlled vehicles（装置）. Most recently Curiosity, a car-size vehicle, traveled through space on an unpiloted spacecraft(航天器) and landed on Mars in August 2012. Directed by NASA scientists , the vehicles move on the surface, taking pictures , collecting and analyzing soil, and looking for signs of life.

But what about human explorers? Plans are already in the works to send astronauts to Mars as soon as the mid-2030s.

_____________________________________

But before you start packing your bags, let’s consider the challenges. For starters, Mars is far away. Just getting there could take up to 10 months.

Scientists already know that time away from Earth’s gravity harms the human body. Bones and muscles get weaker. The body produces less blood. What damage would months and months of living in space do?

And then there is the matter of water, oxygen, food and fuel. Scientists will have to find solutions to these problems, or the first humans on Mars won’t survive very long in their new home.

Tiny Dangers

There’s another tinier risk. It’s so tiny that you can’t even see it: germs.

Some scientists believe that our germs could pollute the whole planet of Mars. Potentially killing Martian life before we have the chance to discover it. Worse, there is a small but terrifying chance that any microscopic life already there might be harmful to us .

Worse still, if any of those Martian germs(火星细菌) were brought back to Earth, the result could be disastrous. Animals, plants, and people could be wiped out.

Worth the $$$?

A more practical concern is the cost. The price could approach $ 1 trillion(万亿). How can we justify spending that much when so many problems—poverty, disease—could use the cash here on Earth?

1.Which of the following is TRUE according to the “A welcoming planet” part?

2.Which of the following can best fill in the blank in the passage?

A. Living in space. B. Limited resources.

3.By “Tiny dangers” the author means ________________.

A. there is no serious danger

B. people won’t be in any danger

C. it’s difficult for people to realize the danger

D. the danger may be caused by very small things

4.Which may cause the biggest danger?

A. Martian germs may be different from those on Earth.

B. Martian germs may be brought back to Earth.

C. People may carry germs to Mars.

D. There may be germs on Mars.
