Wisdom teeth are normally the last teeth to appear. This usually happens when people are in their late teen years or early twenties, in other words, when they are older and wiser.
Wisdom teeth can grow into place normally and never cause a problem. But often there is not enough room for them in the mouth; they might crowd other teeth. Sometimes they even push sideways through the gums (齒齦)
An impacted wisdom tooth is one that fails to completely rise through the gums. Wisdom teeth that only partly break through can leave space for bacteria to enter around the teeth. Infection (感染) is a risk in these cases.
Wisdom teeth that are not well lined and become impacted are often removed. The American Dental Association says removal is generally advised when wisdom teeth only partly break through the gums. Removal is also advised if there is a chance that wisdom teeth are poorly lined. The best time to remove is before the teeth cause any problems or pain. Young adults are the best candidates for wisdom teeth removal.
But why do we have wisdom teeth if we often need to get them removed? One theory has to do with our diets. Scientists say the diet of ancient humans probably required more chewing teeth. Life was probably a little rougher on the teeth back then, too. So it was good to have extras.
68. According to the passage, which of the following statements is NOT true?
A. Just older and wiser people can have wisdom teeth
B. Wisdom teeth can cause problems if not in their right place
C. Impacted wisdom teeth can't grow out of the gum fully
D. Wisdom teeth that only partly break can get bacterial infections
69. Wisdom teeth should be removed ______.
A. when they break through the gums
B. when they are below the gums
C. if they are not well lined or get impacted
D. if they take up enough room in the mouth
70. We can learn from the passage that ______.
A. impacted wisdom teeth have the risk of getting infected
B. ancient humans need chewing teeth because of their happy life
C. older adults are the best candidates for wisdom teeth removal
D. more chewing teeth are needed for the diet of modern humans
71. The main purpose of the passage is to ______.
A. advise B. persuade C. comment D. introduce

“Let me give you an example. 35 teaching here, I also teach out at the community college in Henderson, 17 miles down the freeway from where I live. One day, I drove those 17 miles to Henderson.

I’m still able to teach my class, and I’ve been able to arrange for the tow truck to meet me after class.”
“The secretary’s eyes opened wide, and then she 44 . I smiled back and headed for class.” So ended my story.
