难度：***

The Gisbornes have recently completed a twelve-day trip on their solar-powered electric boat, the Loon. They traveled down the Erie and Oswego canals for twelve days before reaching Albany, New York. Monte Gisbome, the captain of the Loon, said that this marks the first time that anyone has traveled down American canal system using solar electric energy as the primary (主要的) fuel source.

The Tamarack Lake Electric Boat Company designed the Loon. It is a boat with solar panels (太阳能板) mounted (安装在) on its top which provide 738 watts of electricity using energy from the sun. It also has a 48 volt deep-cycle battery that has a range of thirty miles. It has a top speed of five miles per hour.

The boat is "solar-assisted" rather than "solar-driven" because it has a battery charger (电池充电器) which is built into the boat. It can help power the boat when the solar panels do not collect enough energy.

Monte Gisbome talked about the boat in an interview. "The problem with technology these days is that it produces too much heat and too little energy for motion. My boat is at least eight times more efficient than a gas-powered boat, which means that it saves me a lot of money and keeps the environment clean. Even in these technologically advanced times, some of the more popular gas-powered boats are terribly inefficient, which means that they cost a lot of money to use every day, and they make the water very dirty."

He also mentioned that the solar panels can provide the boat with about 16 km of free travel on a sunny day. "For most customers, 16 km is enough and," Monte Gisborne said, "even if you travel 32 km in one day, as long as you don't use it the next day, you have nothing to worry about because the battery won't run out of power."

For this reason, these boats are perfect toys for weekend use but not much more than that. It' s best to leave them in the sun during the week to let the battery charge and then use them on weekends. In other words, if you need to use a boat every day you may still need to use a gas-powered boat.

41. From the passage, we can learn that ______________.

A. the Loon was the first solar-powered boat to set sail in America

B. the Loon gets all its electricity from the sun via solar panels

C. Tamarack Lake Electric Boat Company designed the first solar-powered boat

D. Gisborne first designed the solar panels for the boat

42. What does Gusborne think is the best part of his boat?

A. It is almost as fast as other boats.

B. It only needs to use energy from water.

C. It uses energy more efficiently.

D. Its battery charges quickly.

43. What is the shortcoming of the solar-powered boat?

A. It is not very good for everyday use.

B. It is not environmentally friendly.

C. It is not as fast as gas-powered boats.

D. It is too slow for people who use boats a lot.

44. What can we infer about the solar-powered electric boats from the last paragraph?

A. They can meet the needs of fishermen.

B. They are not as good as gas-powered boats for Sunday boat rides.

C. They are suitable for going out on a lake with the family on Sundays.

D. People who like toys should use them on weekends.

45. The passage mainly talks about ___________.

A. the Gisbornes' 12-day trip to New York

B. the first solar-powered boat across American canal system

C. a new invention to replace gas-powered boats

D. the shortcomings of solar-powered boats for everyday use

答案：

Gisbornes一家完成了12天的运河旅行，不过使这次旅行与众不同的是他们的船主要依靠太阳能来驱使行进。

41. B。 推理判断题。根据文章第二、三段以及最后一段的第二句可知，the Loon的能量来源主要是依靠太阳能。当船运行的时候，太阳能板直接捕捉太阳能并把它转化成电能，而当这种直接获取的电能不够使用的时候，它就使用电池里早已经蓄好的电能作为补充。而从最后一段的第二句可知，电池里的电也是在平常的时候把它放到外面吸收太阳能作为储备的，由此可知B项正确。

42. C。 细节理解题。根据文章第四段的“My boat is at least eight times more efficient than a gas-powered boat, which means that it saves me a lot of money and keeps the environment clean.”可知答案选择C项。

43. A。 推理判断题。根据文章最后一段最后一句“In other words, if you need to use a boat every day you may still need to use a gas-powered boat.”可知这种船不适合每日使用。

44. C。 推理判断题。根据文章最后一段第一句可知如果是周日泛舟湖面的话，这种船还是很适用的。

45. B。 主旨大意题。文章主要讲述了第一条在美国运河航行的由太阳能驱动的电船，the Loon，介绍了它的构造以及优点和缺点等。

[答案]

Advantages of Studying on the Internet

Nowadays the Internet is more and more popular, and I think it's a good way of studying. Firstly, the Internet enables people to study whenever and wherever it's convenient. Secondly, they can also choose to study whatever they are interested in, while a traditional school doesn't provide such great freedom. Thirdly, they can discuss questions with teachers on the Internet immediately they have any questions and assignments can be handed in by clicking it away on the Internet, too.

I love studying on the Internet, for it brings a lot more choices and freedom.
