Unlike modern animal scientists, dinosaur scientists cannot sit on a hillside and use telescopes to watch dinosaurs in order to know how they lived and whether they were good parents Instead, they have to search hard for information from dinosaurs’ fossils(恐龙化石) because dinosaurs died out millions of years ago.

It’s very difficult for the scientists to reach an agreement because different results can be got from the same fossils. Many fossils of the same kind of dinosaurs have been dug out from one place. They might have formed when an entire group of dinosaurs got stuck(陷入)all at once. Or they might have been the result of dinosaurs getting stuck one after another over a course of a few centuries. Thus we can say that dinosaurs might have in the first case lived in big groups and in the second lived alone.

Though there are two different results, dinosaur scientists now generally agree that at least some kinds of dinosaurs lived in big groups. “That’s pretty much settled at this point.” Says Paul Sereno, A kind of dinosaurs called Sauropods left behind tracks in the western United States that appear to run north and south, suggesting that they even moved long distances together.

As to whether dinosaurs cared for their young, dinosaur scientists have turned to the closest living relatives of dinosaurs ― birds and crocodiles ― for possible models. Birds give a lot of care to their young, while crocodiles just help their young to the water. The discovered fossils of dinosaurs sitting on their eggs and staying with their young suggest the parents were taking care of their babies, but we still cannot say that all dinosaurs did the same.

There is still a long way to go before the above questions could be answered. Dinosaur scientists will have to find more proof to reach an agreement.

1.Dinosaur scientists can get information directly by ________.

A. studying dinosaur fossils

B. examining modern animals

C. watching dinosaurs

D. using telescopes

2.What is pretty much settled according to Paul Sereno?

A. Half of the dinosaurs lived alone.

B. Most dinosaurs moved long distances.

C. Many dinosaurs settled in the north.

D. Some dinosaurs lived in big groups.

3.Dinosaur scientists can probably know whether dinosaurs were good parents by ________.

A. watching many kinds of animals

B. studying dinosaurs’ living relatives

C. following the tracks left behind

D. working on dug-out dinosaur eggs

4.Which of the following the according to the 4th paragraph?

A. Birds hardly ay attention to their young.

B. Baby crocodiles can look after themselves well.

C. Some dinosaurs took care of their young.

D. Birds and crocodiles take good care of their young.

For years, the automobile industry has been testing vehicles that use hydrogen as fuel. Now, people across the United States have had a chance to see and even drive cars that get power from hydrogen fuel cells (燃料电池).

But the hydrogen fuel cell is not a new idea. The fuel cell was first invented by Sir William Grove of Britain in 1839. Since then, many different designs, have been invented. There is one place where fuel cells are a proven technology: in space. The American space agency used fuel cells in its Apollo spaceships in the twentieth century.

The most useful fuel cell for transportation purposes is the Polymer Electrolyte Membrane, or P.E.M. fuel cell. It is simple and can operate at temperatures of sixty to eighty degrees Celsius. That is much lower than other fuel cell designs. A P.E.M. fuel cell has two sides divided by a thin membrane (膜). Hydrogen gas is forced through one side where it comes in contact with a reactive material containing the metal platinum(铂). The membrane separates the electrons(电子) from the protons(质子) in the hydrogen atoms. The protons pass through it to the other side of the fuel cell. But the electrons are captured to do work; like powering a motor. Oxygen from the air is forced into the other side of the fuel cell. There, the gas meets the protons that have passed through the membrane. They combine to form water and heat. A single fuel cell does not produce a lot of electricity. But when many fuel cells are combined, they can produce enough electricity to power a vehicle. The product of the chemical reaction that powers fuel cells is water. This makes fuel cells a very clean technology.

Hydrogen fuel cell cars have been slow to develop because of many technical problems that have to be solved. For example, it is unclear how long the membranes in P.E.M. fuel cells will last. Also, fuel cells need water for their chemical reactions. They must be designed to start easily at low temperatures and in dry climates. And smaller, less costly fuel cells must be designed before they can truly take the place of gasoline engines. Now more models of fuel cell vehicles are being tested than ever before. The threat of climate change and the high cost of oil have increased interest in these vehicles that do not cause pollution.

The value of the U.S. penny has been dropping for years. Many countries have stopped using pennies. Is it time for the U.S. to do the same?

Those who think we should keep the U.S. penny offer the following arguments to support their positions:

Prices will increase. If we get rid of the penny, everything will have to be rounded to the nickel (五分硬币), costing us more for everything we buy.

Charities need pennies. There are thousands of small charities that depend on pennies to bring in donations. People think nothing of pouring out their old penny jars to support charity, but they won’t part with nickels so easily.

Nickels cost even more to make. If we get rid of the penny, we will need more nickels in circulation. Nickels cost 7.7 cents to make, 2.7 cents over face value, as opposed to 0.26 cents over face value to make a penny. Since the penny costs 0.26 more than face value to make, the Mint (铸币厂) can make 5 pennies and still lose less money than making 1 nickel.

People who want to retire the penny also have some persuasive arguments, including these:

Pennies waste time. The average American wastes 2.4 hours a year handling pennies, or waiting for people who handle them. This statistics is the result of collecting a number of penny-handling related events, including the 30-second period we sometimes spend waiting for someone who just has to dig through their pockets or purse to find that last cent so they can pay for something with exact change (probably so they don’t get stuck with any more pennies).

Making pennies wastes taxpayers’ money. It costs the U.S. Mint 1.26 cents to make each 1 cent coin, meaning that taxpayers are losing 0.26 of a cent for each one of the 7.4 billion pennies the Mint produces each year.

History will repeat itself. In 1857, the Mint stopped making the half-cent coin, partly because the cost of making it was considered to be no longer needed. Yet, commerce continued without any catastrophic effects. History has shown us that updating the monetary supply in countries where the currency (货币) is very stable has had little, if any, negative effect on the economy, or on people’s acceptance of the coinage.

1.According to people who want to keep the penny, getting rid of the penny 　　　　 .

A. is good for ordinary consumers

B. is especially bad for rich people

C. will be convenient for them

D. may lead to fewer donations to small charities

2.Why do pennies waste time?

A. Because consumers don’t always have enough change.

B. Because it takes time for people to get them from their pockets or purse.

C. Because pennies are not easy to take.

D. Because pennies are difficult to collect.

3.The underlined word “catastrophic” in the last paragraph can be replaced by “　　　　 ”.

A. direct　　 B. positive

C. important　　 D. disastrous

4.The text is mainly developed by 　　　　 .

A. giving examples

B. setting down general rules

C. comparing different opinions

D. following the natural time order
