The first and most obvious thing is that a dictionary will【23】you the spelling of a word. If you're not sure about the spelling of a word, you can try to find the correct spelling in a dictionary. Words are listed in alphabetical order--a, b, e, and so on. For example, on a dictionary page the word "poor"--p, o, o, r--comes before "poverty"--p, o, v, e, r, t, y and the word "poverty" comes【24】the word "power"--p, o, w, e, r. The words are always given in alphabetical order.
The second thing a dictionary will tell you is【25】. Most dictionaries give the pronunciation of a word in a special kind of alphabet. This special alphabet is called a phonetic, or sound alphabet. The phonetic spelling will tell you generally【26】a word is pronounced. There are a few different phonetic alphabets. Many dictionaries use the International Phonetic Alphabet to show pronunciation.
The【27】thing a dictionary will tell you is the meanings of words. You can【28】a word and find out what it means. Many words have more than one meaning, and a good dictionary will explain all of the word's meanings. For example, in English the common word "get" has over 20 different meanings. The meaning, of course,【29】the sentence in which the word is used.
These three things--spelling, pronunciation, and meanings--are some of the important【30】that you learn from dictionaries.

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： There were several important discoveries in the early part of last century that helped geologists develop a more accurate picture of the earth's interior. The first key discovery had to do with seismic waves. Remember they are the vibrations caused by earthquakes. Well, scientists found that they travel thousands of miles through the earth's interior. This finding enabled geologists to study the inner parts of the earth. You see, the studies revealed that these vibrations were of two types: compression, or P waves, and shear, or S waves. And researchers found that P waves travel through both liquids and solids, while S waves travel only through solid matter. In 1906, a British geologist discovered that P waves slowed down at a certain depth but kept traveling deeper. On the other hand, S waves either disappeared or were reflected back. So he concluded that the depth marked the boundary between a solid mantle and a liquid core. Three years later, another boundary was discovered that was between the mantle and the earth's crust. There is still a lot to be learned about the earth. For instance, geologists know that the core is hot. Evidence of this is the molten lava that flows out of volcanoes. But we are still not sure what the source of the heat is.
What is the important discovery about seismic waves mentioned by the instructor？
A．They occur at regular intervals.
B．They can withstand great heat.
C．They travel through the Earth's interior.
D．They can record the Earth's internal temperature.
