dinosaurs?Guess again!You don,t have to go to a museum to see these creatures.They are alive
and swimming in the warm coastal waters of Florida.
Manatees(海牛)have lived a peaceful existence in the warm waters  of  Florida  for  60

something to save them,they will soon go the way of dinosaurs.
Humans have made life very difficult for manatees.One big danger that humans have
introduced is the speedboat.Because manatees are mammals.they need to come to the surface to breathe about every 5 to 6 minutes.This means that they are in constant danger of being caught in the propellers(螺旋桨)of speedboats.And boating aceidents are the greatest cause of death for them.
Manatees are in extra danger when they are in their sleeping or“torpor”state.They still
have to come to the surface for the air,but sometimes they are too sleepy to avoid the danger of approaching boats.
Another danger for manatees is the pollution that humans produce.Due to human pollution,
a deadly plant called red tide had increased greatly in the Gulf of Mexico.The plant,or algae,

down on waste and pollution to protect the waters for the manatees.

C.call dive in the deep sea for hours             D.is the biggest living animal on earth
46.Why is it dangerous for manatees to be in a torpor state?
A.Because they come to the snlface to breathe,and that is when they are hunted.
B.Because they eat deadly algae,and this makes them too sick to avoid danger.
C.Because they live in groups and therefore they are easily hurt by passing boats.

A. His early career

B. His return and Apple's growth

C. His moving back and its effect

D. His memory living on forever

E. Struggling hard for his career

F. Public recognition (承认)of his work

   Steve Paul Jobs was an American businessman and widely recognized as a pioneer of the personal computer revolution(革命). He was co-founder, chairman, and CEO of Apple Company. His death is a great loss to us. The following is some more information about him.

1.

         After Apple's founding, Steve Jobs became a symbol of his company and industry. At the time of his resignation, and again after his death, he was widely described as a pioneer and genius perhaps one of the foremost in the field of business, creation and product design, and a man who had changed the face of the modern world, completely changed at least six different industries. His death was considered a loss to the world by commentators(评论家) across the globe.

2.

         Memorial candles and iPads to Steve Jobs lie outside the Apple Store in Palo Alto, California. Apple has lost a creative genius, and the world has lost an amazing human being. Those who have been fortunate enough to know and work with Steve Jobs have lost a dear friend and an inspiring guide. Steve jobs leaves behind a company that only he could have built, and his spirit will forever be the foundation of Apple.

3.

         As is still clearly remembered, it was not long before Steve Jobs left his office as CEO of Apple. But he remained at the company as chairman of the company's board. Hours after the announcement, Apple shares dropped by five percent in after-hour trading. The relatively small drop, when considering the importance of Steve Jobs to Apple, was associated with the fact that his health had been in the news for several years, and he was on medical leave since January 2011.

4.

         Steve Jobs took a job as a technician at Atari company in California in 1974. He traveled to India in the summer of 1974. Seven months later, he returned to Atari and was assigned to create a circuit board for the game Breakout. With Wozniak, the founder of Atari, Steve Jobs began attending meetings of the Homebrew Computer Club where he got to know Edwin H. Land, the inventor of instant photography and founder of Polaroid Corporation, and modeled his career after him.

5.

         Apple announced that it would buy NeXT for $429 million. The deal was finally made in late 1996, bringing Steve Jobs back to the company he co-founded. In order to concentrate Apple's efforts, Steve Jobs stopped a number of projects. With the purchase of NeXT, much of the company's technology found its way into Apple products. Under his guidance the company increased sales significantly with the introduction of the iMac and other new products. Since then, appealing designs and powerful branding have worked well for Apple.

 

 

 

The Green Microgym in Portland,Oregon has all the usual stuff you'd expect-sweaty people,loud music,smooth exercise equipment-but it has some extras as well. Everywhere you look,there are power wires. And these aren't the typical kind that let you surf the Web while you ride a spin cycle-although. you can do that too.The gym uses special exercise equipment that captures(捕获)the energy you create while riding, converts(转换)it into electricity and channels it into the power outlets(插座).

The idea of using exercise equipment to produce electricity is not new. A gym in Hong Kong has been doing this since 2007. But clean (and healthy)energy is just now starting to catch on in U. S. gyms·"We have seen a significant increase in interest in the past six months,which is a good sign that fitness centers are ready to spend money on green technologies,” says Mike Curnyn,co-founder of the Green Revolution,a Connecticut-based firm that wires bikes into a central battery that can store energy.

The Green Microgym,first opened in 2008,has more than 200 members and is doing so well that owner Adam Boesel opened another one five miles from the original.Although membership costs about the same as ordinary gyms,customers can earn gift certificates from local businesses for watts produced while exercising.An average workout creates 37. 5 watt hours,which is enough to power a phone for a week.

Boesel uses spin bikes made by Resource Fitness,a Seattle company he co-owns,that captures energy produced from the flywheel. Wires send the converted AC current(交流电流) into any standard wall outlet-for this reason,the product line's name is Plug Out-and the energy created is used before the building draws power from the grid(电网).Unlike the Green Revolution equipment,Plug Out machines cannot store extra energy. A third company,the Florida-based ReRev,is adding converters to a specific brand of spin bikes. But since the converters add$1,000 to the price of the equipment,the ReRev and Green Revolution machines are at a disadvantage.

Resource Fitness,by contrast,sells its equipment for the same$1,200 price as non- electricity-producing machines,removing the question of how long it will be until the energy savings pay for the cost of the unit.The company can afford to do this because its designs don’t call for the extra wiring needed for battery packs and large converters.It is also trying to price competitively with standard equipment so more gyms-and gym goers-will make the switch.

1.Members of the Green Microgym earn gift certificates for_______.

A .using the man-powered exercise equipment

B. saving electricity for local businesses

C. producing green electricity to power their phones

D. paying higher membership fees

2.The spin bikes made by Resource Fitness are different from those by Green Revolution in that_______.

A. they are easier to ride

B. they are more expensive

C. they don't have wires connected

D. they can not store extra electricity

3.What might prevent the green exercise equipment from getting more popular?

A .People's unwillingness to go green.

B. The high cost of making it.

C. Safety problems concerning electricity.

D. Lack of certificates.

4.The underlined words“make the switch”in the last paragraph most probably mean_____.

A. change to a different gym

B. use green exercise equipment

C. switch on the spin bikes

D. add a battery to the machine
