5 . At our residence, we made sure a small lawn (草坪) space remained green by watering regularly. I live in an area _________ by a fairly large garden. There are a number of fruit trees _________ here along with many plants and lots of grass. That _________ the flying beauties — the birds visiting the space regularly. At first sight, the garden appears very _________ but actually many birds live in it or visit it _________ . Some people keep birds in _________ to listen to their songs. I say it is _________ better for the birds to live freely.

Every morning I am awakened by the shrill _________ of a magpie-robin. The sound is so sweet and I just lie in bed listening to the songs _________ the bird flies away. Small plants and bushes provide good __________ for insects and very small birds, while larger trees will attract visits __________ more birds and mammals. They come to sing, __________ a bit or look for food. So it is always a(n) __________ to see them. I just sit quietly and they __________ their business undisturbed.

It’s easy to attract birds to your __________   however small and close it is to a city. I have seen the spotted-dove, pigeon and various other little birds which I cannot __________. They sing, dance and __________ their beautiful colors. It is quite a(n) __________. On the other hand there are those annoying little sparrows that come into the house to __________ food.

__________ to say, the surrounding area is being developed and the wildlife is being chased away or destroyed.

9 . A couple of weeks ago, my husband got a text asking him to help cut down a tree. “This is not the time of year to cut down trees,” I said to my husband, “They are full of birds’ nests. Wait until fall, until the baby birds have flown away.”

The tree didn’t seem like an urgent issue to me or my husband, but it was worrying our neighbor and she wanted it gone. So, with some unwillingness and a chainsaw (链锯), my husband and our sons headed to our neighbor’s house early Saturday morning. About an hour later, I got a phone call from my 14-year-old son. He spoke in a trembling voice, which made me worried. I grabbed my keys, expecting to be told to meet my husband and sons at the emergency room. But no, everyone was safe. My son said that birds’ nests had fallen out of the tree and some baby birds had been hurt. So, I grabbed an old towel and a laundry basket.

I put the birds in the basket and headed for the Wildlife Rehabilitation Center. The people there are not astounded to see worried people with laundry baskets containing injured animals. They sighed at my story — they had heard many stories like this. They knew exactly how to help these birds. I was relieved that the birds would be fine, but I was still upset they had been needlessly traumatized (使受精神创伤).

A lesson from this experience is that we need to look at the whole picture. We must behave in ways that help meet needs without causing harm to others, Our efforts to move through our lives with more gentleness and care may make a big difference for someone, whether it’s a baby bird or a person.

10 . An air-conditioner has become a sign of middle-class status in developing nations. But as air-conditioners appear from windows and storefronts across the world, scientists are becoming increasingly alarmed about the impact of the gases on which they run.

The oldest CFC coolants used in air-conditioners, which are highly damaging to the ozone layer, have been largely rejected from use; and the newest ones, used widely in industrialized nations, have little or no effect on the ozone layer. But these newest gases have an another impact — they contribute to global warming thousands of times more than CO2 does, the standard greenhouse gas. Indeed, the leading scientists in the field have just calculated that if all the equipment entering the world market uses the newest gases currently employed in air-conditioners, up to 27 percent of all global warning will result from those gases by 2050.

So the treatment to cure one global environmental disaster is now seeding another. "There is precious little time to do something, to act," said Stephen O. Andersen, the co-chairman of an international organization's technical and economic advisory panel.

Promising technologies wait, blocked in the wings. In China and a few other countries, room air-conditioners using hydrocarbons — which cause little warming or ozone damage — are already coming off assembly lines in small numbers but have not yet been approved for sale, in part because the chemicals are flammable (易燃的).Yet in Europe, refrigerators that cool with hydrocarbons have been in use for years, and some companies in the United States, such as Pepsi and Ben and Jerry's, have recently changed in-store coolers from HFCs to hydrocarbons as part of sustainability plans. But the patent is being argued. And some governments have still not finished safety testing.

Mr. Wypior, whose agency is trying to promote climate-friendly air-conditioning industries in India and China, said: “The technologies are available. They're well known. They're proven— though not at scale. So why aren't we moving?”
