A big shark is stuck in a canal (运河) in South Korea (韩国). It is more than three metres long. The shark has been there for three weeks. People call it Bukangi. Many people go to see it every day.
Some people tried to help the shark go back to the sea. They used a big net, but the net hit some rocks. Experts say the city lights and noise make the shark lose its way.
Now experts hope the seawater will help the shark. They think it can find its way by itself. They say warm sea water brings more sharks near the country.
1.1. What does the passage say about the shark?
A It is a baby shark.
B It is over three metres.
C It is three weeks old.
D It is in the sea.
解析:选B。B 细节理解题。原文第一段明确说“It is more than three metres long.”,其中“more than”与选项B中的“over”是同义替换,都表示“超过三米”,因此B正确。A说它是小鲨鱼,文中没有依据;C说它三周大,原文只是说“has been there for three weeks”,意思是它被困在运河里三周了,不是年龄三周;D说它在海里,但原文说它被困在韩国的运河里,与事实相反。
2.2. What did people use to help the shark?
A A big net.
B A small boat.
C A police car.
D A long rope.
解析:选A。A 细节理解题。原文第二段说“They used a big net”,意思是人们用了一张大网去帮助鲨鱼,因此A正确。B“小船”、C“警车”、D“长绳”在文中都没有提到,属于无中生有,所以不能选。
3.3. What makes the shark lose its way?
A The warm sea water.
B The big rocks there.
C Too many people watching.
D The city noise and light.
解析:选D。D 细节理解题。原文第二段说“Experts say the city lights and noise make the shark lose its way.”,直接指出城市灯光和噪音让鲨鱼迷路,因此D正确。A“温暖的海水”在文中是说会带来更多鲨鱼靠近这个国家,不是让鲨鱼迷路的原因;B“大石头”是网碰到石头,不是鲨鱼迷路的原因;C“太多人观看”虽然文中提到很多人去看它,但并没有说这是它迷路的原因。
4.4. What do the experts hope?
A People will take the shark away.
B The shark will stay in the canal.
C The shark can find its way home.
D The shark will become famous.
解析:选C。C 细节理解题,带有简单的同义转换。原文最后一段说“Now experts hope the seawater will help the shark. They think it can find its way by itself.”,意思是专家希望海水能帮助鲨鱼,认为它可以自己找到路,结合前文人们想帮它“go back to the sea”,可知专家希望鲨鱼能找到回家的路,因此C正确。A说人们会把鲨鱼带走,文中没有提到;B说鲨鱼会留在运河里,与专家希望它回到海里的意图相反;D说鲨鱼会出名,虽然人们叫它Bukangi并去看它,但这不是专家希望的内容。
5.5. What is the passage mainly about?
A A big shark in trouble.
B How to catch a shark.
C Why city lights are bad.
D A shark living in the sea.
解析:选A。A 主旨大意题。全文讲一条大鲨鱼被困在韩国运河里,人们想办法帮助它,专家也希望它能自己找到回海里的路,所以文章主要讲的是“一条陷入困境的大鲨鱼”,A最合适。B说“如何抓鲨鱼”,但文中人们用网是为了帮助鲨鱼,不是抓它;C说“城市灯光为什么不好”,这只是文中提到的一个细节,不能概括全文;D说“一条生活在海里的鲨鱼”,与原文中鲨鱼被困在运河里不符。
