Long Beach, a 28-mile area of beach, lies in southwestern Washington, and is generally called Long Beach Peninsula. Communities there take you back to old days of a simple life. Here, visitors can relax and enjoy the good of a total rest.

Bird watching

There are different kinds of birds on Long Beach. It’s best if you watch them from a distance and don’t try to frighten them. The Southwest Loop Route Map can be got through the Long Beach Peninsula Visitors Office by calling 1-800-451-2542.

Horses

A popular activity on Long Beach is horseback riding. Two businesses in the city of Long Beach offer guided horseback tours along the beach: Black Country Wilderness Outfitters and Skipper’s Equestrian Center. You may also bring your own horse. Among the adventures offered with horses is a wagon(四轮马车)ride along the beach, a carriage ride through Seaview or Long Beach, a back country pack trip, or a sunset ride by horseback on the beach.

Camping

RV(活动房屋式旅游车)and tent camping aren’t allowed on the beach. Camp fires are allowed within 100 feet off the beach, but must be away from the dry grass.

Swimming and other activities

Swimming is allowed, but you must be careful. The waters are very cold and dangerous. Surfing(冲浪)is advised only for experienced surfers. Beach driving is allowed at certain areas on the beach. The speed limit is 25 mph. Building sand castles, digging sand to find something, riding bicycles and flying kites are also popular activities in the area.

Enjoy your trip to Long Beach, Washington!

A biologist from the National Park Service discovered a rare and unusual mammoth(猛犸) skull(颅骨) buried in a 13,000-year-old rock layer on the Santa Rosa Island, the second largest landmass in the Channel Islands, California. The fossil of the extinct giant animal is leaving many paleontologists(古生物学家) scratching their heads. Despite the fact that it’s possibly the best preserved mammoth skull ever found and of high scientific importance, the species of the individual it belonged to can’t seem to be identified yet—it’s too big to be a pygmy(特别矮小的) mammoth and too small to have come from a Columbian mammoth. Some say it’s a new species while others believe the truth lies somewhere in between.

The first mammoths showed up in North America around two million years ago, but it was only during the last two ice ages that the Columbian species, which could grow to be up to 14 feet tall, made its way to the Channel Islands 100 miles west of Los Angeles. Once the ice melted, many populations became trapped on the island and evolved into pygmy mammoths, an endemic species(地方种) to the Channel Islands which grew only to six feet tall.

Judging from its size, the newly found mammoth skull doesn’t seem to fit any of the two species, Columbian or pygmy. To make things even more confusing, one of its two tusks(象牙) is nearly five feet long and coiled in a manner that resembles those of fully grown mammoths but the left tusk is shorter and sloped, more like a juvenile(青少年).

This has caused some scientists to say the Santa Rose skull may belong to a transitional species. Whatever’s the case, a following examination of the mammoth’s teeth should put the matter to rest. The analysis will also tell us how old the mammoth was when it died, so we can tell for sure whether it was an adult or juvenile.

More interesting than the mammoth’s lineage, however, might be its story. The giant mammal lived 13,000 years ago or roughly the same timeline of the “Arlington Man”, a 13,000-year-old human skeleton also found on Santa Rosa. Some 3,000 years later humans were already spread throughout the continent and the Channel Islands’ mammoth went extinct. The present finding might help reveal a link between the two.

The remains also seem to confirm a long-held assumption that there were two mammoth migrations to the Channel Islands. “The discovery of this mammoth skull increases the probability that there were at least two migrations of Columbian mammoths to the island: during the most recent ice age 10,000 to 30,000 years ago, as well as the previous ice age that occurred about 150,000 years ago,” said USGS geologist Dan Muhs.

1.The underlined part in the first paragraph means the paleontologists feel ________.

A. excitedB. confusedC. anxiousD. frustrated

2.Which of the following is not among the reasons why the newly found skull is special?

A. It is possibly the best preserved mammoth skulls.

B. Its size fits neither the Columbian mammoth nor the pygmy mammoth.

C. It was found on the Santa Rose Island, California.

D. Its two tusks give out different information of the mammoth’s age.

3.What can be inferred from the last three paragraphs?

A. The examination of the mammoth’s teeth can tell us how old it was when it died.

B. There may be a link between the extinction of mammoths and the spread of humans.

C. At least two mammoth groups migrated to the Channel Islands during different periods of time.

D. There remains no final conclusion as to how many mammoth groups migrated to the Islands.

4.This passage mainly tells us the newly found mammoth skull _________.

A. is among the best preserved, but with a mysterious story

B. has aroused a debate over what species it belongs to

C. is of great scientific importance to mankind

D. is likely to confirm a former assumption

In summer, millions of people will head for the beach.And while the ocean can be a great place to swim and play, it may also be useful in another way. Some scientists think that waves could help make electricity.

“Have you ever been on a surfboard or boat and felt yourself being lifted up by a wave? Or have you jumped in the water and felt the energy as waves crashed over you?” asked Jamie Taylor of the Wave Energy Group at the University of Edinburgh in Scotland.“There is certainly a lot of energy in waves.”

Scientists are working on using that energy to make electricity.Most waves are created when winds blow across the ocean.“The winds start out by making little ripples (波纹) in the water, but if they keep on blowing , those ripples get bigger and bigger and turn into waves, ” Taylor said.“Waves are one of nature’s ways of picking up energy and then sending it off on a journey.”

When waves come towards the shore, people can set up dams or other barricades to block the water and send it through a large wheel called a turbine (涡轮) .The turbine can then power an electrical generator (发电机) .

The United States and a few other countries have started doing research on wave energy , and it is already being used in Scotland.

The resource is huge.We will never run out of wave power, besides, wave energy does not create the same pollution as other energy sources, such as oil and coal.

Oceans cover three quarters of the earth’s surface.That would make wave power seem perfect for creating energy around the world.There are some drawbacks, however.

Jamie Taylor said that wave power still cost too much money.He said that its effects on animals in the sea were still unknown.Plus, wave power would get in the way of fishing and boat traffic.

With more research, however, “many of these problems might be overcome,” Taylor said.“Demand for energy to power our TVs and computers, drive our cars, and heat and cool our homes is growing quickly throughout the world.Finding more energy sources is very important, for traditional sources of energy like oil and gas may run out some day.”

In the future, when you turn on a light switch, an ocean wave could be providing the electricity!

1.Which of the following is NOT true?

A.Wave power costs too much money.

B.Wave energy creates the same amount of pollution as other energy sources.

C.Wave power affects fishing and boat traffic.

D.Wave power may affect marine animals.

2.We can infer from the passage that ______.

A.finding new energy sources like wave energy is important

B.wave energy is a resource that will never run out and is used all over the world

C.wave power is perfect for creating energy around the world

D.wave power doesn’t create any pollution

3.The underlined word “drawbacks” in the seventh paragraph probably means______.

A.regrets B.adventures

C.disadvantages D.difficulties

4.What can be the best title for the passage?

A.How to Get Electricity by Waves.

B.A Huge Resource of Energy.

C.Can Waves Make Electricity?

D.The Disadvantages of Wave Energy.
