答案17 B 18 A 19 B 20 C
解析
W Dear Teddy
Having a noisy neighbor is a really common problem especially for people who live in an apartment
Like you I also had a noise problem with a neighbor He’d watch loud movies every night sometimes until 3 in the morning One night I decided I’d had enough of the noise so I went to my neighbor’s apartment and we argued However that only made him turn his TV up even louder every night after that
A week or so later I saw my neighbor outside Even though we’d lived next to each other for a long time the first time we’d spoken was when we had our argument
So I chatted with him and got to know him better—I also made a joke about how I liked his taste in movies
That night the noise problem stopped It seemed that all I had to do was get my neighbor to see me as a friend not an enemy
So my advice to you is to be calm and patient with your neighbor
One day go over and ask if you can come in for a talk If you mention that their noise is affecting your studies they should soon change their mind
At the same time however not everyone is comfortable with facing people this way If you’re one of those people write a polite and friendly letter instead explaining your problem to your neighbor
Many people we know can make us angry but usually the best way to win someone over is through kindness
