Attracting and feeding wild birds are entertaining activities that have long been enjoyed by people all over the world. Feeding birds has become so popular that prepared feed mixtures are readily available. We feed birds for many reasons. Many pleasant hours can come from watching birds. A hobby often develops into a serious study of their habits. Accurate identification of birds is usually the first goal. But observations that an amateur bird-watcher can make are really limitless.
There is, however, responsibility associated with bird feeding, including a disease hazard. Attracting numbers of birds continually to the same spot can be harmful to them, particularly species that pick food from the ground contaminated by the droppings of other birds. In winter, feeding efforts are most satisfying to people and are of greatest benefit to birds. During this time, when fewer natural foods are available and air temperatures are lower, extra feeding can keep a bird warm and well. Once begun, feeding should never stop during these lean months.
If you start a local increase of birds, be prepared to do what may be required to eliminate hazards to those you want to befriend. A constant supply of food should be given until the cold is over and spring has come. If feeding is stopped during severe weather, birds used to relying upon the feeders might starve.
Questions:
What does the speaker say about bird-watching?
What does the speaker say about birds fed continually on the same spot?
What does the speaker suggest we do when feeding birds in winter?
选项
A、They can harm nearby plants.
B、They may catch some disease.
C、They fight each other for food.
D、They may pollute the environment.
答案
B
解析
推断题。本题询问关于总在同一地点喂养鸟儿作者说了什么。根据原文可知,持续在同一地点喂养大批鸟儿会使鸟儿有生病的危险。它们会食用其他鸟儿粪便(droppings)污染过的食物,这样对鸟儿非常有害,由此可以推断出,鸟儿可能会生病,故选B。
