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. 【M1】
