Tests conducted by French police indicated that the driver, who also died in the crash, was intoxicated and likely caused the accident while trying to escape the paparazzi photographers who consistently tailed Diana during any public outing.
Sixteen years earlier, nearly four billion people in 74 countries had tuned in to witness the marriage of Prince Charles, heir to the British throne, to Lady Diana, a young English school teacher. Married in a grand ceremony at St Paul's Cathedral in the presence of 2,650 guests, the couple's romance was for the moment the envy of the world.
However, before long the fairy-tale couple grew apart, an experience that was particularly painful under the ubiquitous eyes of the world's tabloid media.
In August 1996, two months after Queen Elizabeth II urged the couple to divorce, the prince and princess reached a final agreement.
In exchange for a generous settlement, and the right to retain her apartments at Kensington Palace and her title of princess, Diana agreed to relinquish the title of "Her Royal Highness" and any future claims to the British throne.
In the year between the divorce and her fatal car accident, the popular princess seemed well on her way of achieving her dream of becoming "a queen in people's hearts."
听力原文： Objects that are vibrating make sounds．Rhythmic sound vibrations produce sound waves which travel in every direction．The frequency of a sound is the number of waves that pass a given point each second．The more rapidly an object vibrates，the greater the frequency of sound it makes．Frequency is measured in hertz．One hertz equals one sound wave per second．The frequency of sound determines the degree of highness or lowness of the sound．A high-pitched sound has a higher frequency than a low-pitched sound．Humans hear sounds that have frequencies from about 20 hertz to 20,000 hertz。Sound with a frequency higher than 20,000 hertz is called ultrasound which is too high-pitched for humans to hear．However，many animals can hear ultra- sound．Bats can hear higher sounds than any other animal．Some can hear up to 210,000 hertz．Bats send out lots of high-pitched squeaks and then listen to the echoes bouncing off things like insects．The shorter the time interval between the squeak and the echo，the closer they are to the insect．Using sound to find or“see” things is called echolocation．Another animal that uses ultrasound is the dolphin．Dolphins can hear sounds up to about 150,000 hertz．Dolphins use sound waves to find food underwater．They make clicking sounds that hit whatever is around them and then bounce hack to the dolphins．Dolphins can send as many as 2,000 clicks per second．Dolphins' ultrasound ability is so sensitive that they can detect small fish from 10 feet away．

SECTION B PASSAGES
Directions: In this section, you will hear several passages. Listen to the passages carefully and then answer the questions that follow.
听力原文： Today we're going to evaluate the main tool used when addressing groups the voice. There are three main elements that combine to create either a positive or negative experience for listeners. They can result in a voice that is pleasing to listen to and can be used effectively. Or they can create a voice that doesn't hold attention, or even worse, causes an adverse reaction.
The three elements are volume, pitch, and pace; When evaluating volume, keep in mind that a good speaker will adjust to the size of both the room and the audience. Of course, with an amplifying device like a microphone, the speaker can use a natural tone. But speakers should not be dependent on microphones—a good speaker can speak loudly without shouting.
The second element, pitch, is related to the highness or lowness of the sounds. High pitches are, for most people, more difficult to listen to, so in general speakers should use the lower registers of their voice. During a presentation, it's important to vary pitch to some extent in order to maintain interest.
Pace, that is how fast or slow words and sounds are articulated, should also be varied. A slower pace can be used to emphasize important points. Note that the time spent not speaking can be meaningful, too. Pauses ought to be used to signal transitions or create anticipation. Pauses can be very effective when moving from one topic to another.
What's the main point the speaker makes？
A．Content of speech is more important than tone of voices.
B．Voice quality has a strong effect on listeners.
C．Effective speakers must use visual aids.
D．Amplifying devices are essential in large rooms.
