听力原文： One of the great joys of gardening is to share a garden with wildlife, especially birds. Attracting birds to a garden is made easier by following a few basic guidelines. (20) All birds depend on plants for shelter, nest and roosting sites, and food. To the extent that your yard offers some or all of these features, it can become a heaven for birds' life. As a general rule, the more native plants are planted in the yard, the more birds will come. Some birds are so particular that you must have the special plant that they demand while others only demand that you provide their basic needs. Most birds require some shelter for roosting, preening and sleeping. (21) By varying the height as well as the density of plants, a greater number of species are encouraged to seek out shelter in your yard. Nesting requirements in birds are quite varied. (21) To encourage as many different types of birds as possible, vary the types of plants, use a number of native plants, and vary the height of plants. Birds eat seed, fruits, or nectar, as well as insects found on plants. Again, diversity encourages more birds, particularly plants that bloom in different seasons. (22) One of the surest ways to encourage birds in a yard, especially a new yard, is to provide water. If you have pets or wandering cats, move the water higher, beyond their reach. Leave the water in the open, With no overhanging branches. Change the water often, especially in the warm weather, and remove algae buildup with a scrub brush rather than chemical treatments.

听力原文： (23) Almost 20,000 whales have been slaughtered since a ban on commercial whaling was introduced in 1986 and the death toll is rising each year. Norway and Japan killed over 1,000 whales in 1999 and they plan to kill even more. The International Whaling Commission (IWC) has failed to stop the killing and a compromise deal may relax the ban allowing coastal whaling—condemning many thousands more whales to a cruel death. In 1994, the IWC created a whale sanctuary in Antarctic waters and many believed the battle to save the whales had been won. But Japan has ignored the sanctuary and along with Norway continues to defy the whaling ban. As the environmental concerns increase, whaling is no longer the issue as it was or deserves to be. With little public awareness of the increasing whale slaughter, there has been no pressure to stop it. Consequently, the political will to confront the whalers and .enforce the whaling ban has slipped away. Commercial whaling has devastated whale populations worldwide, pushing the entire species to the brink of extinction. (24) There is still great scientific uncertainty about the size and status of remaining whale populations. Whales are facing increasing threats to their survival including increasing toxic pollution, massive over-fishing, entanglement in fishing nets, boat collisions, habitat loss, ozone depletion and climate change. They need to be protected, not hunted. (25) Commercial whaling is appallingly cruel and unnecessary. It is morally indefensible. It should be condemned to history, to a time when sadly we knew no better!
