It’s 2022 now. A five-month-old bird has set a new record for long-distance migration(迁移) after flying 13,560 kilometers without stopping over a period of 11 days. The old one had been set two years ago by another bird that had covered 12,000 km (7,500 miles) in 11 days.

Millions of birds set for the sky for a long and quite hard journey to get away from the coming cold, feed, and have babies for the next few months. A lot of them travel through distances of over 10,000 kilometers (6,200 miles). This year, a staggering 13,560 kilometers (8,425 miles) was covered by a bird without stopping and setting a new Guinness record in the process. That was hard to believe.

This happened last month when the young bird finished its journey from Alaska to New Zealand for the winter. The bird took a little detour that added 500 kilometers to its first plan of a journey. The five-month-old bird took off on October 13 from the Yukon Kuskokwim Delta in Alaska, followed the usual route(路线) across the Pacific Ocean down to New Caledonia and through the Tasman Sea, before making an unexpected 90-degree turn towards Tasmania rather than New Zealand.

Scientists were able to know the bird’s record flight(飞行) with the help of a tiny tracker(追踪器) that only weighed 5 grams. Eric Woehler of Birdlife Tasmania says that the bird lost “half or more of its body weight,” during the 11-day flight, but it made it arrive at the dry land safely.

1.When was the old record set?

A In 2019.

B In 2020.

C In 2017.

D In 2021.

解析：选B。B数字计算题。根据第一段第一句“It’s 2022 now.”以及最后一句“The old one had been set two years ago by another bird that had covered 12,000 km (7,500 miles) in 11 days.”可知，上一次记录是在(2022-2=)2020年创下的。故选B。

2.What does the underlined word “staggering” mean?

A Surprising.

B Worrying.

C Boring.

D Relaxing.

解析：选A。A词义猜测题。根据前面提到的大多数鸟类飞行了超过10000公里(6200英里)的距离，以及下句的“That was hard to believe.”可知，这只五个月大的鸟不间断飞行了13560公里，这令人难以置信。故选A。

3.Why did the five-month-old bird start its journey?

A To play with its friend.

B To bring food back.

C To find its mom.

D To spend the winter.

解析：选D。D细节理解题。根据第三段第一句“This happened last month when the young bird finished its journey from Alaska to New Zealand for the winter.”可知，这只鸟从世界的一端直飞另一端是为了度过寒冷的冬天。故选D。

4.The bird is ________ after the flight.

A bigger

B thinner

C heavier

D stronger

解析：选B。B细节理解题。根据最后一句的“Eric Woehler of Birdlife Tasmania says that the bird lost ‘half or more of its body weight,’ during the 11-day flight”可知，这只鸟经过这次飞行后掉了一半的体重。故选B。

5.What is the best title for this text?

A Bird Loves Flying Freely.

B Bird Turns To Be Five Months Old.

C Bird Sets A New Guinness Record.

D Bird Steals A Tiny Tracker.

解析：选C。C主旨大意题。本文主要讲述了一只小鸟打破不间断飞行纪录的故事。故选C。
