No More Mystery in the Neighborhood
Last week, in a quiet neighborhood, something strange happened. Residents heard noises in the night but no one knew why. Victor thought that it was teenagers having fun while his wife and neighbor, Helen, blamed it on animals.
【示例】
We now know what was happening in the neighborhood. A ranger’s station(护林站)is being built in the nearby forest.
Trees had to be cut down to make space for the station. This affected some animals living in the forest. A raccoon(浣熊)family lost their home and had problems finding food.
The raccoons discovered food in the neighborhood’s garbage bins(垃圾桶),so they came back every night.
Now the mystery is solved. People in the neighborhood feel sorry for the raccoons and they are trying to help them.

I found a pink wallet when I was cleaning the classroom. It can’t be a boy’s because none of them likes the color. Who can the wallet belong to
There are only two girls who said they lost their wallets. They are Lily and Lucy. And a pink hairpin is in the wallet, so the wallet might belong to Lily.
But it is hard to know the answer because both Lily and Lucy like pink.
Then I found a bank card in the wallet. Now there is no doubt that the wallet belongs to Lucy. She is the only one who has a bank card in our class.

Grammar
【短语解析】
be sure是表示肯定的意思，表不确定时为be not
sure, be/make sure 在祈使句中表示“确保、肯定”。
例: 保证你可以在早上六点到达那里。
Be sure you will get there at six in the morning.
确保答案是正确的。
Make sure the answers are right.
2. So I might be a bit late for the party.
因此我可能聚会要晚到一点。
eg: That’s a bit too expensive.
The speaker spoke up a bit/a little to make.
【短语解读】
a bit和a little都作“一点儿”讲，但用法不同。
(1)a bit和a little在肯定句中修饰动词、形容词、
副词和比较级时可以互换，表示“一点儿”的意思。
eg: He has a bit of／a little money left.
She knows a bit of ／a little French.
a bit用作定语时，意为“一点儿”，不能直接修饰不可数名词，但可用“a bit of ＋不可数名词”结构，此时a bit of ＝ a little．
