Question 42-46
Listen to a talk at the campus bird-watchers' club
We've talked before about using special plantings, water, and feeders to attract birds to

your garden. This afternoon I'd like to tell you about a less wellknown way to attract

birds. It's by putting out eggshells. Many birds eagerly consume them. Perhaps it is a mass

of replacing culch and lost by females and (), though I have seen males eat the shells too.

Anyway, I have had at least eight different species of birds come to eat the eggshells.

Here is how it's done. You should save your eggshells in winstonman water, then cook them

lightly on the baking pan in the oven; set at a low temperature until they are dry but not

brown. This stylizes them and makes them brittle. You can quantle them into bisides to

pieces and spread them on the ground a rock or a bird seater. You may find them so popular

you want to go to your favorite resteraunt to ask for more eggshells.


44. How are the eggshells prepared?
a They are dried in the sun
b They are soaked in water
c they are cooled in the refrigerator.
d They are baked in the oven
答案为什么是d而不是b?


45. How does the preparation process affect the shells?
a It makes them clean and free of germs
b. it makes them more visible for the birds
c it makes them more nutritious
d it makes them softer

答案为什么是a ?
