Naz and Omar are trash workers. One day,they were working as usual. A trash bin fell off their truck. Inside, they found a dog. The dog was very weak. The workers called their boss (老板), Alex. Alex pulled the dog out of the bin and gave him some food. The dog ate quickly. Alex took the dog to a vet (兽医) for help. Later, he adopted (收养) the dog and named him PJ. A small accident saved a life.

1.1.What are Naz and Omar’s jobs?

A Teachers.

B Trash workers.

C Drivers.

D Vets.

解析：选B。B细节理解题。文章第一句直接交代了“Naz and Omar are trash workers.”，说明他们的职业就是垃圾工，信息明确，无需推断。A选项“教师”、C选项“司机”和D选项“兽医”在文中均未提及二人的职业身份，因此不能选择。故选 B。

2.2. What fell off the truck?

A A dog.

B A box.

C A trash bin.

D A bag.

解析：选C。C 细节理解题。文中清晰写道“A trash bin fell off their truck.”，掉下来的是垃圾桶本身。有些同学可能会误选A“一只狗”，但原文说的是在垃圾桶里面发现了一只狗，是垃圾桶先掉下来，狗在桶里，狗并非直接掉落的物体，所以要仔细分辨。B选项“盒子”和D选项“袋子”文中没有出现，因此排除。故选 C。

3.3. How was the dog?

A Very strong.

B Very weak.

C Very fat.

D Very noisy.

解析：选B。B细节理解题。发现狗之后，文中明确描述“The dog was very weak.”，这是对狗状态的原句复现。A选项“非常强壮”与原文意思相反，C选项“非常胖”和D选项“非常吵闹”在文中均没有提及，故不正确。故选 B。

4.4. Who adopted the dog in the end?

A Naz.

B Omar.

C PJ.

D Alex.

解析：选D。D细节理解题。文末提到“Later, he adopted the dog and named him PJ.”，这里的“he”指代的是前文出现的Alex。Alex把狗带去看兽医，随后收养了它，取名为PJ。PJ是狗的名字，不是领养人，所以C选项错误。Naz和Omar是发现狗的垃圾工，但他们并没有领养，所以A、B选项也不符合事实。故选D。
