填空题

You should not fear spiders thanks to their poison. Of all the spiders in (1)______
North America, only one kind is really dangerous and most would not bite if
they were handled. They much prefer to run away or dropping to the ground (2)______
on a thread of silk. Even so, when a spider runs directly toward a person, it
gives impression that it is about to attack. Actually, it cannot see the person (3)______
on its way. The spider is too short-sighted to see things at the distance. It (4)______
only wanted to go where it won’ t be disturbed. In America one kind of spider (5)______
is responsible for the frightened reputation of the rest. It is the Black Widow. (6)______
Such called because the female, which is larger than the male, often eats her (7)______
husband after making love. The Black Widow is found in all states or is most (8)______
common in the south and the west. She constructs a loose, irregular web
under a pile of ruin or near the foundations of buildings where she is seldom (9)______
disturbed. She is not an attacking spider and many people have proven this by
letting her to crawl over their hands. When she bites, it is usually in self- (10)______
defense. In spite of the stories you may have had heard, it is rare for a person
to be bitten by a Black Widow and even more unusual for the bite to prove

she should be respected.
