Not long ago I was invited to dinner by a girl called Jane. I had only met Jane twice, and she was very beautiful. I was very pleased. “She likes me,” I thought. “I am so sorry we asked you at such short notice.” She said when I arrived, “but we suddenly realized there were going to be thirteen people at the table, so we had to find someone else,” Believing that the number 13 is unlucky is a typical of superstition(迷信). Recently I came across a little group of worried people. They gathered round a man lying on his side beside a road in London. They were waiting for an ambulance, because the man had been knocked down by a passing taxi. He had stepped off the pavement and into the street in order not to walk under a ladder. To see a black cat in England is lucky. But if you see a black cat in India, it is considered very unlucky. There, if you are about to set out on a long journey, and someone sneezes, you should not go. If you break a mirror you will have seven years’ bad luck..

It is hard to track the blue whale, the ocean’s largest creature which has almost been killed off and is now listed as an endangered species. Joining radio equipment to it is difficult and observing with human eyes are too unreliable to learn about its behavior.

So biologists were pleased early this year when with the help of the Navy(海军) they were able to track a particular blue whale for 43 days monitoring(监视) its sounds. This was possible because of the Navy’s formerly top-secret system of underwater listening equipment across the oceans. Tracking whales is only one example to show that an exciting new world is opening its window to civilian scientists after the cold war as the Navy starts to share its network of underwater listening system built over the decades to track the ships of potential enemies.

Scientists announced at a news conference recently that they had used the system for closely monitoring a deep-sea volcanic eruption for the first time. It is proposed that the network should be used to track ocean currents and measure global temperatures.

The speed of sound in water is roughly one mile a second--slower than through land but faster through air. Different layers of ocean water can act as channels for sounds conveyed to them in the same way a stethoscope (听诊器)does when it carries faint noises from a patient’s chest to a doctor’s ear. This focusing is the main reason that even relatively weak sounds in the ocean especially low frequency ones can often travel thousands of miles.

1.The passage is chiefly about ___       _.

       A.an effort to protect an endangered marine species

       B.the civilian use of a military detection system

       C.the exposure of a U. S. Navy top-secret weapon

       D.a new way to look into the behavior of blue whales

2.The underwater listening system was originally designed ___    __.

       A.to mark and locate enemy ships

       B.to monitor deep-sea volcanic eruptions

       C.to study the movement of ocean currents

       D.to replace the global radio communications network

3.The deep-sea listening system makes use of _____.

       A.the complex technology of focusing sounds under water

       B.the capability of sound to travel at high speed

       C.the special quality of layers of ocean water in sending out sound

       D.low-frequency sounds traveling across different layers of water

4.According to the passage, sound travels faster through______________.

       A.water than land                                    B.air than land

C.air than water                                      D.land than air

5.It can be learned from the passage that _____.

       A.new radio equipment should be developed for tracking the endangered blue whales

       B.military technology plays an important role in scientific research

       C.civilian scientists will do little without the help of military technology

       D.blue whales are no longer endangered with the use of the new system

Though X City may not be as well-known for public transportation as some other cities in the country, it does offer buses, the light rail, the subway and taxis to make life without a vehicle possible.

   If you’re a college student, there’s an additional resource available -- the X City’s Network. Started in 1999, the Network is essentially funded by the schools, but about 17 percent comes through fundraising. Around 70,000 riders a year use the Network, which runs for the duration of the academic year. Stops are at the various campuses as well as the Town Center, the Inner Harbor, the railway station and the City Square.

  Students from seven schools like and use the network. Not only is it free and they know exactly what to expect, but also it's a safe ride.

  If you’ve got a bicycle and are in the mood for some exercise, you can take advantage of several bicycle paths throughout the city. The two main paths are the G Falls path and the J Falls path. The G Falls path starts at Lily Park. The J Falls path runs from Daffodil Park to the railway station, passing by several historic attractions.

  If you don’t have the patience to wait for the buses or the light rail, or don’t want to have to make several transfers, then you might want to take a taxi. Cabs run up and down the main streets and can be easily found at the Inner Harbor or other such centers of activity. If you’re a little bit out of the way, though, you will probably have to call one of the several cab companies and have them send a cab to your location.

  Staying in town, neighborhoods all have multiple transportation services if you don’t have a car. You can make various choices to do shopping, to the movies, to baseball games, to museums, to the malls and even to work. So, even if you don’t have a car here, that shouldn’t prevent you from moving easily.
