我们的第10篇练习A new study has found that 176 kinds of birds around the world are building their nests(鸟巢) with rubbish from humans, such as cigarette butts(烟头) and plastic bags. Aren't birds supposed to use things in nature, like grass, leaves and other parts of trees, to build their homes? Yes, they used to. But now things are different. A group of European scientists studied about 35,000 bird nests and found that birds now use man-made materials almost everywhere on Earth. Interestingly, some rubbish seems helpful, which is why birds “like” adding it to their nests. For example, cigarette butts have some chemicals(化学物质), 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, human rubbish can also harm birds. Chemicals in cigarette butts can hurt baby birds, making them sick or shortening their lives. Worse, if the cigarette fire isn't completely out, it can set nests on fire. Seabirds often add fishing nets to their nests, which can trap(困住) them, putting their lives in danger. Our friends in the air are living a hard life because of some human activities. To improve the situation, people should not smoke or leave rubbish near trees. Strict rules must be set, and those who break them will receive punishment. Also, we can help by building artificial(人工的) nests that are warm and safe for birds to use. This would reduce the need for birds to collect harmful materials and protect them from the dangers caused by human rubbish。A study shows that 176 bird species now use human rubbish, like cigarette butts and plastic bags, to build nests. These materials offer benefits, such as keeping insects away, offering protection for baby birds and 9.____. However, 10.____. To solve the problems, people should avoid 11.____.
