The reef you’d be looking at is made up of glass sponges(海绵). But how can animals be made of glass? Well, glass is formed from a substance called silica. The sponges use the silica found in ocean waters to build glass structures that will give them shape and support. Be careful! Some of the fragile creatures are up to 200 years old.
When sponges die, new ones grow on top of the pile of old ones. Over centuries, a massive and complex reef takes shape. Some sponges look like wrinkled trumpets, while others look like overgrown cauliflower or mushrooms.
Dr. Paul Johnson, who discovered the Washington reef in 2007, also found other surprises such as bubbles of methane(甲烷) gas flowing out of the seafloor nearby. The methane feeds bacteria, and the bacteria feed the glass sponges.
“It’s a new ecosystem we know nothing about,” said Dr. Johnson.
The reef of yellow and orange glass sponges is crowded with crabs, shrimp, starfish, worms, snails, and rockfish. The glass reef is also a nursery for the babies of many of these creatures and was called a “kindergarten” by scientists.
Many animals that live in the reef hang around for a long time, just like the sponges. Rockfish, for example, live for more than 100 years. Scientists are just beginning to study all the species that call the reef home.
The Washington coast isn’t the only place where a living glass reef has been found. The first was discovered in Hecate Strait off the coast of British Columbia in 1991. Scientists all over the world were stunned to see it.

Hamilton isn’t the only educator crossing the Atlantic. Schools in France, Egypt, Singapore, etc, have also recently made top-level hires from abroad. Higher education has become a big and competitive business nowadays, and like so many businesses, it’s gone global. Yet the talent flow isn’t universal. High-level personnel tend to head in only one direction: outward from America.
The chief reason is that American schools don’t tend to seriously consider looking abroad. For example, when the board of the University of Colorado searched for a new president, it wanted a leader familiar with the state government, a major source of the university’s budget. “We didn’t do any global consideration,” says Patricia Hayes, the board’s chair. The board ultimately picked Bruce Benson, a 69-year-old Colorado businessman and political activist (活动家) who is likely to do well in the main task of modern university presidents: fund-raising. Fund-raising is a distinctively American thing, since U.S. schools rely heavily on donations. The fund-raising ability is largely a product of experience and necessity.
Many European universities, meanwhile, are still mostly dependent on government funding. But government support has failed to keep pace with rising student number. The decline in government support has made funding-raising an increasing necessary ability among administrators and has hiring committees hungry for Americans.
In the past few years, prominent schools around the world have joined the trend. In 2003, when Cambridge University appointed Alison Richard, another former Yale provost, as its vice-chancellor, the university publicly stressed that in her previous job she had overseen “a major strengthening of Yale’s financial position.”
Of course, fund-raising isn’t the only skill outsiders offer. The globalization of education means more universities will be seeking heads with international experience of some kind of promote international programs and attract a global student body. Foreigners can offer a fresh perspective on established practices.

Let"s start with a very simple white puffy cloud — a cumulus cloud（积云）. How much does the water in a cumulus cloud weigh? Peggy LeMone, senior scientist at the National Center for Atmospheric Research in Boulder, Colorado, did the numbers. "The water in the little cloud weighs about 550 tons," she calculates. "Or if you want to convert it to something that might be a little more meaningful … think of elephants."
The thought of a hundred elephants-worth of water suspended(悬浮的) in the sky begs another question — what keeps it up there?
"First of all, the water isn"t in elephant-sized particles（微粒）, it"s in tiny tiny tiny particles," explains LeMone. And those particles float on the warmer air that"s rising below. But still, the concept of so much water floating in the sky was surprising even to a meteorologist like LeMone. "I had no idea how much a cloud would weigh, actually, when I started the calculations," she says.
So how many elephant units of water are inside a big storm cloud—10 times bigger all the way around than the "puffy" cumulus cloud? Again, LeMone did the numbers: About 200,000 elephants.
Now, ratchet up(略微调高) the calculations for a hurricane about the size of Missouri and the figures get really massive(巨大的). "What we"re doing is weighing the water in one cubic meter theoretically pulled from a cloud and then multiplying by(乘上) the number of meters in a whole hurricane," she explains.
The result? Forty million elephants. That means the water in one hurricane weighs more than all the elephants on the planet. Perhaps even more than all the elephants that have ever lived on the planet.
小题1:The weight of is NOT mentioned in the passage.
| A．a cumulus cloud | B．a tornado |
| C．a hurricane | D．a storm cloud |
| A．She found it not convincing. |
| B．She thought it needed further calculations. |
| C．She was quite surprised at it. |
| D．She considered the calculations inaccurate. |
| A．A storm cloud weighs about 200,000 elephants. |
| B．The water in a hurricane weighs more than that in any other kind of cloud. |
| C．There are less than forty million elephants living on the earth. |
| D．The water in the cloud is in very tiny partials. |
| A．How Much a Cloud Weighs | B．How Much a Hurricane Weighs |
| C．Surprising Results | D．Elephants in the Sky |
Charles Wiesenthal, who was born in Germany, designed and received a patent on a double-pointed needle that eliminated the need to turn the needle around with each stitch (缝合) in England in 1755. Other inventors of that time tried to develop a functional sewing machine, but each design had at least one serious imperfection.
Frenchman Barthelemy Thimonnier finally engineered a machine that really worked. However, he was nearly killed by a group of angry tailors when they burned down his garment factory. They feared that they would lose their jobs to the machine.
American inventor Elias Howe, born on July 9, 1819, was awarded a patent for a method of sewing that used thread from two different sources. Howe’s machine had a needle with an eye at the point, and it used the two threads to make a special stitch called a lockstitch. However, Howe faced difficulty in finding buyers for his machines in America. In frustration, he traveled to England to try to sell his invention there. When he finally returned home, he found that dozens of manufacturers were adapting his discovery for use in their own sewing machines.
Isaac Singer, another American inventor, was also a manufacturer who made improvements to the design of sewing machines. He invented an up-and-down-motion mechanism that replaced the side-to-side machines. He also developed a foot treadle (脚踏板) to power his machine. This improvement left the sewer’s hands free. Undoubtedly, it was a huge improvement of the hand-cranked machine of the past. Soon the Singer sewing machine achieved more fame than the others for it was more practical. It could be adapted to home use and it could be bought on hire-purchase. The Singer sewing machine became the first home appliance, and the Singer company became one of the first American multinationals.
However, Singer used the same method to create a lockstitch that Howe had already patented. As a result, Howe accused him of patent infringement (侵犯). Of course, Elias Howe won the court case, and Singer was ordered to pay Howe royalties (版税). In the end, Howe became a millionaire, not by manufacturing the sewing machine, but by receiving royalty payments for his invention.
小题1:Barthelemy Thimonnier’s garment factory was burned down because __________.
| A．people did not know how to put out the fire |
| B．Elias Howe thought Thimonnier had stolen his invention |
| C．the sewing machines couldn’t work finally |
| D．workers who feared the loss of their jobs to a machine set fire |
| A．Because the judge was against Singer for his unfriendly attitude. |
| B．Because Howe had already patented the lockstitch used by Singer. |
| C．Because Singer had borrowed money from Howe and never repaid it. |
| D．Because Singer and Howe had both invented the same machine. |
| A．A Stitch in Time Saves Nine |
| B．The Case between Howe and Singer |
| C．Patent Laws on the Sewing Machine |
| D．The Early History of the Sewing Machine |
Today, sustainable development is a proper trend in many countries. According to a recent study, the global market for low carbon energy will become three times bigger over the next decades. China, for example, has set its mind on leading that market, hoping to seize chances in the new round of the global energy revolution. It is now trying hard to make full use of wind and solar energy, and is spending a huge amount of money making electric cars and high speed trains. In addition, we are also seeing great growth in the global markets for sustainable products such as palm oil， which is produced without cutting down valuable rainforest. In recent years the markets for sustainable products have grown by more than 50%.
Governments can fully develop the potential of these new markets. First, they can set high targets for reducing carbon emission (排放) and targets for saving and reusing energy. Besides, stronger arrangement of public resources like forests can also help to speed up the development. Finally, governments can avoid the huge expenses that are taking us in the wrong direction, and redirecting some of those expenses can accelerate (加速) the change from traditional model to a sustainable one.
The major challenge of this century is to find ways to meet the needs of growing population within the limits of this single planet. That is no small task, but it offers abundant new chances for sustainable product industries.
小题1: The traditional business model is harmful because of all the following EXCEPT that ______.| A．it makes the world warmer |
| B．it consumes natural resources |
| C．it brings severe damage to forests |
| D．it makes growth hard to continue |
小题2:What can we infer from Paragraph 2?| A．China lacks wind and solar energy. |
| B．China is the leader of the low carbon market. |
| C．High speed trains are a low carbon development. |
| D．Palm oil is made at the cost of valuable forests. |
小题3:To fully develop the low carbon markets, government can ______.| A．cut public expenses | B．forbid carbon emission |
| C．develop public resources | D．encourage energy conservation |
小题4:We can learn from the last paragraph that businesses have many chances to ______.| A．develop sustainable products |
| B．explore new natural resources |
| C．make full use of natural resources |
| D．deal with the major challenge |
小题5:What is the main purpose of the passage?| A．To introduce a new business model. |
| B．To compare two business models. |
| C．To predict a change of the global market. |
| D．To advocate (提倡) sustainable development. |
