Birds are building their nests(巢)with rubbish，said a new study. The rubbish includes cigarette butts(烟头)and plastic bags.

A group of European scientists looked into about 35,000 bird nests. They found that birds from almost everywhere on the earth except Antarctica have used man-made things in nests.
Some rubbish seems to be helpful. This is why birds “like” putting it in their nests. For example，cigarette butts have some chemicals，so they can keep insects away and protect the baby birds. Plastic bags are useful in keeping the birds warm. And other hard things，such as paper cards，can make nests stronger.
However，in the end，human rubbish may only bring more harm to birds. The harmful chemicals in cigarettes hurt the baby birds. They may get sick or have shorter lives.
To make matters worse，if the cigarette still burns when the bird brings it back to its home，it may set fire to the nest. Pieces of the fishing net(渔网)may also trap birds，and it's impossible for them to get out by themselves. If the baby birds eat other kinds of rubbish by accident，they will also get hurt. Our friends in the air are feeling the bad effects(影响)of humans polluting the environment.
(B)1. How did the European scientists get their findings?
A. By doing thousands of tests.
B. By studying a lot of bird nests.
C. By looking through a lot of studies.
D. By watching the birds for a long time.
(A)2. Why can plastic bags “help” birds?
A. Because they can keep birds warm.
B. Because they can keep insects away.
C. Because they can make nests stronger.
D. Because they can protect the baby birds.
(A)3. What does the underlined word “trap” in the last paragraph mean?
A. Keep birds in a place.
B. Help to feed birds.
C. Let birds fly away.
D. Make birds feel comfortable.
(B)4. What are the last two paragraphs mainly about?
