问题     You should not fear spiders thanks to their poison. Of all the spiders in   【M1】______
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       【M2】______
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 【M3】______
on its way. The spider is too short-sighted to see things at the distance. It   【M4】______
only wanted to go where it won’ t be disturbed. In America one kind of spider   【M5】______
is responsible for the frightened reputation of the rest. It is the Black Widow.【M6】______
Such called because the female, which is larger than the male, often eats her   【M7】______
husband after making love. The Black Widow is found in all states or is most    【M8】______
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   【M9】______
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-   【M10】______
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
fatal But remember that her poison is powerful and even though she is shy,
she should be respected.
