[单项选择]It is commonly supposed that the health of Long Island Sound is chiefly the responsibility of the shoreline communities in Long Island, Westchester County and Connecticut. This is largely true. It is also true, however, that New York City has long been a major contributor to the environmental ills that torture this noblest of American estuaries.
The main reason is four old municipal sewage treatment plants on the East River. Every day of every year, these plants deposit hundreds of thousands of gallons of partly treated wastewater into the river, which then, with tidal certainty, propels the polluted water into the Sound itself
The most damaging of the pollutants leaving the plants is nitrogen—useful as a fertilizer on land but, in sufficient quantities, fatal to bodies of water like the Sound, where it stimulates the growth of bacteria and algae and robs the water of oxygen. This condition is known as hypoxia, and it suppresses marine life. Roughly half the nitrogen comes fr

Somewhere on the South CoastEnglandDear Mum and Dad, It was a great idea to send me over to Britain to learn English this summer! I’ve met so many students from Sweden, France and all over the world. And there are lots of students from Germany here too. It’s just like being at home. What a relief to find normal people, even in England, and to speak in a normal language most of the time. Of course, we do have English lessons in the day, and I have to talk to the family I stay with here. Do you know, some of my friends have said they won’t go out with us in the evening any more—they want to speak English and find English friends. I think they’re mad. The family I live with are very nice. But they have some strange habits. They drink tea all day: at breakfast, in the afternoon and at bedtime. And they eat butter with salt in it! If I go out in the evening, I often eat fish and chips. The food is wrapped up in a news paper; at least reading the paper takes your mind off the fish and chips! Here at the coast, we travel by bus. The buses are always late. I was knocked down by an old lady the other day because I didn’t stand in the queue. English people seem very quiet and reserved, so I was very surprised to see how violent they become about queues. Also, if you ask them directions, they suddenly become very chatty and go on for hours. I’d like to come back here next year to see all my friends again—oh yes, and to learn some more English... Your loving son, Hans

A. they are wildly interested in English
B. they are angry with me
C. they are becoming wild in England

Traditional IP packet forwarding analyzes the (1)IP address contained in the network layer header of each packet as the packet travels from its source to its final destination. A router analyzes the destination IP address independently at each hop in the network. Dynamic (2) protocols or static configuration builds the database needed to analyze the destination IP address (the routing table). The process of implementing traditional IP routing also is called hop-by-hop destination-based(3) routing. Although successful, and obviously widely deployed, certain restrictions, which have been realized for some time, exist for this method of packet forwarding that diminish its (4). New techniques are therefore required to address and expand the functionality of an IP-based network infrastructure. This first chapter concentrate on identifying these restrictions and presents a new architecture, known as multipleprotocol (5)switching, that provides solutio
