While in Banff, make time for a walk around town. A special treat is to go up the mountainside on the Banff Gondola for a surprising view of the valley below. Here is The pines, whose cook has developed a special way of mixing foreign food such as caribou, wild boar, and reindeer with surprising sauces.

Best time to visit is during the off-season, from early May to mid-June, or in October. This way you can avoid sharing the high way with mobile homes which can be pulled by cars. But whatever the season, take some lunch with you from Banff, because there are only a few food stops on the road.

Forty minutes north of Banff, side by side with the Banff National Park, sits world-famous Lake Louise. This surprisingly small body of water is attractive with towering mountains around it. Glaciers, huge masses of ice, moving very slowly against rocks, produce what is called glacier rock flour, making its water dark to see. It is worth taking a walk around the grounds of the Chateau Lake Louise, another beauty, proud of its early 20^th century history.

Back on the road, and it’s time to continue north past the astonishing Columbia Icefield, then turn off the highway and take the short road to the base of the Athabaska Glacier. You can rent ice cleats (夹板) and do some climbing or do a more pleasant snowmobile tour. Either way, you can enjoy endless beautiful sights.

Finally you’ll reach Jasper, the usual turning around the place for the Banff-Jasper loop (回路). It’s worth riding the Jasper Skytram, and be sure to visit the wonderful Jasper Park Lodge, also dating back to the 1920s. If you can have lunch there, do it. The restaurant has an adventurous menu and their wine list would put a smile on any visitor’s face.

Nuclear power's danger to health, safety, and even life itself can be described in one word; radiation(辐射).

    Nuclear radiation has a certain mystery about it, partly because it cannot be detected (探测) by human senses. It can't be seen or heard, or touched or tasted, even though it may be all around us. There are other things like that. For example, radio waves are all around us but we can't detect them, sense them, without a radio receiver. Similarly, we can't sense radioactivity without a radiation detector. But unlike common radio waves, nuclear radiation is not harmless to human beings and other living things.

    At very high levels, radiation can kill an animal or human being completely by killing masses of cells in important organs (器官). But even the lowest levels can do serious damage. There is no level of radiation that is completely safe. If the radiation does not hit anything important, the damage may not be significant. This is the case when only a few cells are hit, and if they are killed completely. Your body will replace the dead cells with healthy ones. But if the few cells are only damaged, and if they reproduce themselves, you may be in trouble. They reproduce themselves in an unusual way. They can grow into cancer. Sometimes this does not show up for many years.

This is another reason for some of the mystery about nuclear radiation. Serious damage can be done without the knowledge of the person at the time that damage has occurred. A person can be irradiated(放射治疗) and feel fine, then die of cancer five, ten, or twenty years later as a result. Or a child can be born weak or easy to get serious illness as a result of radiation absorbed by its grandparents.

     Radiation can hurt us. We must know the truth.

According to the passage, the danger of nuclear power lies in __________.

A. nuclear mystery              B. radiation detection

C. radiation level                 D. nuclear radiation

Radiation can lead to serious results even at the lowest level ________.

A. when it kills few cells             B. if it damages few cells

C. though the damaged cells can repair themselves

D. unless the damaged cells can reproduce themselves

Radiation can hurt us in the way that it can _____.

A. kill large numbers of cells in main organs so as to cause death immediately

B. damage cells which may grow into cancer years later

C. affect the healthy growth of our younger generation

D. lead to all of the above results

Which of the following can be best inferred from the passage?

A. The importance of protection from radiation can be overemphasized (过分强调).

B. The mystery about radiation remains unsolved.

C. Cancer is mainly caused by radiation.

D. Radiation can hurt those who do not know about its danger.
