     There are about 5,000 different kinds of ladybugs in the world. They come in many different colors. Their bright colors warn other animals or insects not to eat them. Ladybugs taste bad. A bird or a frog that eats a ladybug will remember the bright colors and it will not eat another ladybug with the same colors again. When ladybugs are in danger, they will give out a fluid(液体)that tastes terrible.

In many cultures, the ladybug is considered to be a symbol of good luck. Most ladybugs are kind to humans. They eat other insects which destroy crops. One ladybug can eat up to 5,000 insets in its lifetime.

Ladybugs have six short legs. They live in many different places, including green lands, forests, cities, the countryside and along rivers. Different ladybugs have different spots(点). Some of them don’t have spots at all. The most common kind in North America is the 7-spotted ladybug. The 7-spotted ladybugs are the most active from spring to autumn. When the weather turns cold, they look for a warm place to sleep, such as under stones or in houses.根据短文内容，判断下列句子是否正确，对的涂(A),错的涂(B)。
