Scientists have searched for many years for a method to tell whether a volcano（火山）explosion will be small or large. Now，four scientists say they have discovered something in lava（熔岩）that will help do this. They did the research on Mount Unzen on the southern Japanese island of Kyushu.
Mount Unzen exploded in November，1990. Since then，more explosions have killed 43 people and destroyed the homes of more than 2，000 others. The volcano is still active today.
The scientists say the lava of the volcano contains high level of an element（成份），which is a sign of the presence of the lava from deep in the earth，not from the surface. They say it shows that the lava coming directly from inside the earth is connected with huge explosions instead of smaller ones.
The scientists examined the lava from 18 explosions of Mount Unzen that took place during many thousands of years. They also studied the lava from other volcanoes in the area that are older than Mount Unzen. The lava studied came from both large and small explosions. The scientists found that large explosions contained more of the element than small ones. The scientists say if they had known this two years earlier，they could have warned the people living in the area near Mount Unzen and saved many lives.

Have you ever argued with your loved ones over simple misunderstandings（误解）？Little wonder. We often believe we're more skillful in getting our point across than we actually are，according to Boza Keysar，a professor at the University of Chicago. In his recent study，speakers tried to express their meanings using unclear sentences. Speakers who thought listeners understood were wrong nearly half the time. Here‘s some good advice to reduce misunderstanding：
（1）Don't trust what you see from the listener. Listeners often nod，look at you or say“uhhuh”to be polite or move the conversation along. But it‘s easy to consider these as signs of understanding.
（2）Train the editor（编辑）in your head. If you say，“Beth discusses her problems with her husband，”it's not clear whether she‘s talking to her husband or about him. Try instead，“Beth talks to her husband about her problems.”or“Beth talks to others about the problems with her husband.”
（3）Ask listeners to repeat your message. Introduce your request by saying“I want to be sure I said that right.”Questions like“How does that sound？”or“Does that make sense？”may also work.
（4）Listen well. When on the receiving end，ask questions to be sure you're on the same page. After all，it isn‘t just the speaker's job to make his speech understood.
第 58 题 Why does the writer give us the advice？
A．We're not skillful enough to make clear sentences.
B．Misunderstanding is damaging our normal lives.
C．Misunderstanding occurs now and then.
D．It's impolite to say NO to others.
