There are a growing number of pet owners who feed pets on raw, which means, "uncooked"
meat and bones.William Burk, a pet food specialist from the Food and Drug Administration(FDA), believes that feeding raw meat to pets is against its goal of protecting the public fromhealth dangers; besides, raw meat and bones do not have all the required nutrition (营养) that a petneeds every day.
Recognizing how popular these foods are, the FDA has provided guidelines for producers ofpet foods that contain uncooked meat for dogs, cats, and other pets.The guidelines give rules toprotect pet owners and pets from dangers about food safety and lack of nutrition.
Pet owners who feed raw meat and bones should deal with these products very carefully toprotect themselves against possible dangers, says Burk.Just as when preparing foods for humans,use hot water and soap to wash hands, containers, and surfaces that come into contact(接触) withthe food.Don' t put your hands near your mouth until you' ve washed them, and don' t allow yourpet to touch your face right after it has eaten meat.
If owners choose to feed bones to their pets, they should watch their pet carefully when it iseating bones.Burk also says, "If the pet eats a big piece of bone that won' t pass through the digestive system(消化系统), it could kill the pet."

原文翻译及答案解析
有越来越多的宠物主人用未加工的，也就是未煮过的肉和骨头来喂他们的宠物。威廉·伯克，一位来自美国食品与药品管理局的宠物食品专家，认为用未经加工的肉喂宠物违背了保护公众防止其受到健康威胁的目标。此外，未经加工的肉和骨头不能提供宠物每天所需的所有营养物质。
知道这些食物有多么受欢迎之后，美国食品与药品管理局为宠物食品的生产商们提供了指导方针，这些食品包括狗、猫和其他宠物吃的未经加工的肉。这些指导方针列出了一些规则来保护宠物主人和宠物以免遭受有关食品安全和缺乏营养的危险。
伯克说，喂未经加工的肉和骨头的宠物主人应该非常小心地处理这些食品以保护自己免遭可能的危险。正如为人类做饭一样，要用热水和肥皂去洗手、洗容器，并洗一些可能与食物有接触的表面。洗手之前不要把手放在嘴边，在宠物刚刚吃过肉之后不要让宠物碰到你的脸。如果主人选择喂宠物骨头，那么在宠物吃骨头时，一定要在旁边看着。伯克还说，“如果宠物吃一大块不能通过它的消化系统的骨头的话，那会要了它的命。”
63.D【精析】推理题。题干意为“威廉·伯克如何看待喂宠物未煮熟的东西这件事?”由本文第一段可知，伯克认为用未经加工的肉喂宠物有违保护公众防止遭到健康威胁的目标。此外，未经加工的肉和骨头不能提供给宠物们所有它们所需要的营养物质，故D正确。

There are some objects in the sky that move so quickly that sometimes you only see them outof the comer of your eye.These are some of the huge number of bits of rock and dust that are floating around in space, called meteoroids.Normally, we cannot see them at all, but if they travel tooclose to the Earth, they get caught by the pull of the Earth, and begin to fall towards us.They fallfaster and faster, until they hit our atmosphere (大气层), by which time they are going so fast thatthey begin to bum up, and all that you see is a flash of light that moves very quickly across the skyand disappears.These shooting stars, or meteors as they are properly called, are quite common,and sometimes you may see several in a night.
Most meteoroids are very small bits indeed, and they bum up long before they get to theEarth.However, a very few do manage to get all the way through the atmosphere, and actually fallto the ground.usually they do not do much damage, although this is not always the case.
Meteoroids that actually manage to reach the Earth are called meteorites.Most countries haveplaces where meteorites have struck the Earth.some of these places are very large indeed and aretourist attractions.
67.Why do some objects from outer space fall to the ground?
A.They are too big.
B.They are hit by huge rocks.
C.They move too fast.
D.They are pulled by the Earth.
68.What do we know about meteors from the text?
A.They become a star in the sky.

D.They do damage to the Earth.
69.What happens to most meteoroids coming into the atmosphere?

原文翻译及答案解析
天空中许多物体移动速度如此之快,以至于有时它们在你眼前转瞬即逝.它们是漂浮在空中被称为流星体的许多巨大的岩石和灰尘的碎片.通常我们根本看不见它们,但是如果它们太靠近地球,就会被地球引力吸住,开始向我们掉落.它们下降的速度越来越快,直到它们穿过大气层,那时它们的速度如此之快以至于它们开始燃烧,你所能看到的只是一道光划过天空,然后消失不见.这些疾驰的星星,或称流星(他们恰当的称谓),是十分常见的.有时候一晚上就可以看见好几个.
事实上大多数流星体都非常小,在它们到达地球之前就已经燃烧了很久.然而只有很少的能够一路穿过大气层,真正地掉落到地面.通常它们不会造成什么伤害,虽然也有例外.
真的到达地面的流星被称为陨石.大多数国家都有一些地方有陨石掉落.事实上某些地方的陨石如此之大,已经成了旅游景点.
67.D【精析】细节题.题干意为“为什么外太空的一些物体会掉落到地面?”根据文章第一段第三句“Normally,we cannot see them at a11.but if they travel too close to the Earth.they get caught by the pull of the Earth,and begin to fall towards US.”可知,作者认为通常我们根本看不见它们,但是如果它们太靠近地球,它们就会被地球引力吸住,开始向我们掉落,故D正确.
68.C【精析】细节题.题干意为“从文中我们对流星有哪些了解?”从文章第一段第四句话可知,那时它们的速度如此之快以至于它们开始燃烧,你所能看到的只是一道光划过天空,然后消失不见.由此推出,流星消失得非常快,故C正确.
69.A【精析】推理题.题干意为“大部分流星在穿过大气层时会发生什么?”由文章第一段可知,那时它们的速度如此之快以至于它们开始燃烧,你所能看到的只是一道光划过天空,然后消失不见.由此推出,流星穿过大气层时会燃烧,故A正确.
70.D【精析】细节题.题干意为“‘meteorites’(第三段第一行)是指那些__________的石头碎片.”根据本文第三段第一句话“Meteoroids that actually manage to reach the Earth are called meteorites.”可知,真的到达地面的流星被称为陨石,故D正确.
