“Without music, life would be a mistake,” famous German philosopher（哲学家）Friendrich Nietzsche said over a century ago. Music is a big part of our lives. But in recent years, some US schools have cut music classes to control budgets（预算）.
For example, Chicago public schools hurt arts education when it firedover 1,000 teachers. Among
九年级英语二模联考试题卷第10页（共18页）
them, 10 percent of the teachers taught art or music, according to The Washington Times. In fact, this is not just a problem in the US. In other countries, such as China and the UK, music classes are not thought to be as important as ones like science, math and history. That’s partly because music is not seen as a very important life skill, and it isn’t tested. Many stude nts are busy with schoolwork, so parents and students choose to focus（关注）on subjects that are tested more often.
However, learning music is useful in many ways.
When playing music, you need different abilities to work together. It is not as simple as it looks, according to Kenneth Guilmartin of Music Together, an early childhood music development program. For example, when playing the piano, people see music notes and decode（解码）them in their brains. They also use their fingers to make sounds. You need to deal with all these things at the same time.
Music has a special connection with science as well. You can see that many scientists are good at playing music: Einstein played the violin, and German physicist Max Planck did well in playing the piano.
83. Some schools in the US cut music classes, because ______.
A.they were too difficult to learn
B. students in the US weren’t interested in music
C. the schools wanted to control budgets
D. there weren’t enough music teachers in the US
84. In Paragraph 2,what d oes the underlined word“them” refer to（指代）?
A. Fired teachers.
B. Public schools.
C. Parents in Chicago.
D. Students in Chicago.
85. What’s the main idea of Paragraph 4?
A. Playing the piano needs people to see music notes.
B. Playing the piano needs people to use fingers to make sounds.
C. Decoding music notes is needed while we are playing music.
D. Different abilities are needed to work together while we are playing music.
86. How many scientists who are good at playing music are mentioned in this passage?
A. One.
B. Two.
C. Three.
D.Four.
87. What’s the writer’s opinion according to this passage?
A. Music is as simple as it looks.
B. Music classes should be cut in some schools.
C. Music is a big part of our lives.
D. Music isn’t a very important life skill for us.

Much meaning can be carried clearlywith our eyes, so it is often said that eyes can speak.Do you
九年级英语二模联考试题卷第11页（共18页）
have such kind of experience? In a bus you may look at a stranger, but not too long. And if he finds that he is being looked at, he may feel uncomfortable. It’s the same in daily life. If you are looked at for more than necessary, you will look at yourself up and down, to see if there is something wrong with you. If nothing goes wrong, you will feel angry toward the person who is looking at you that way. Eyes do speak, right?
Looking too long at someone may seem to be impolite. But sometimes things are different. If a man looks at a woman for more than 10 seconds, it may mean that he wishes to attract her attention, to make her understand that he loves her. When two people are in a conversation, the speaker will only look at the listener from time to time, in order to make sure that the listener does pay attention to what he or she is saying. Lovers will enjoy looking at each other or being looked at for a long time, to show something that words cannot express.
Clearly, eye contact（接触）should be done according to the relationship between two people and the place where you stay.
88. What can our eyes carry clearly according to the passage? （不超过5个词）
