【題目】

New research has found the longest living animal on Earth with a backbone is a shark.

The research, published in Science Magazine, found the Greenland shark is the longest living animal with a backbone in the world. The gray-colored sharks live in the cold water of the Arctic and are named after Greenland, the world's largest island. After examining one of these sharks, scientists decided it was born in the icy water about 400 years ago and died out recently.

An international team of biologists and physicists was able to estimate （估計(jì)）the ages of 28 dead female Greenland sharks by studying the lenses of their eyes. It is a new way to learn the age of an animal. Eight of the sharks were probably 200 years old or more, and could even have been 300 years old. That would make them older than some whales, which earlier were believed to have been the oldest animals at about 211 years old, according to the Associated Press.

This discovery also means that Greenland sharks can live more than three times longer than humans. Many people these days can expect to live into their eighties. African elephants average about 70 years. The oldest of the Greenland sharks the scientists studied was nearly 5 meters long. It was thought to have been 392 years old when it was caught four years ago. However, because the testing method is so new, it is not exact.

The study's lead expert is Julius Nielsen, a marine biologist from Denmark. He says the 392 number could have an error range （誤差范圍）of 120 years in either direction. That means the shark was probably born sometime between the years 1500 and 1740, with 1620 being the most likely.

"It's an estimate. It’s not a determination, “Nielsen said. "It is the best we can do."

Even at the lowest age, the shark would have been 272 years old when it died and still would be the longest-living animal with a backbone, Nielsen said.

“I don't know why they get so old, but I hope someone will find out, "Nielsen said.

【4】Which of the following statements is NOT true according to the passage?

A.The oldest of the Greenland sharks was nearly five meters long.

B.It can make sure that the oldest Greenland shark was 392 years old.

C.Julius Nielsen says the 392 number could have an error range of 120 years.

D.Julius Nielsen has tried to estimate the probable time the shark was born.

【題目】

The coast redwood is the unchallenged tallest of North American's trees. But do you know it grows from a seed (種子) that is smaller than a pea?

What's special about redwoods?

Redwoods are special for a couple of reasons. The first is their size. Imagine standing next to a tree which is the height of a 30-floor building. The second is their age. Redwoods usually grows to about 600 years old. Some are even more than 2000 years old.

Where do redwoods grow?

To find a coast redwood, you'll have to go to Oregon or California. The land along the west coast, about 450 miles long and up to 35 miles wide, is home to the redwoods. Coast redwoods do not grow anywhere else in the world.

Why do redwoods grow there?

The coast of the Pacific Ocean provides a special environment for the redwoods. Cool, wet air comes from the ocean and keeps the trees wet all year. That is important because most of the rain falls between October and May. During the dry summer months, the trees depend on the wet air over the coast.

How do redwoods survive?

Redwoods have a couple of protection systems(系統(tǒng)). The skin of an adult redwood tree can grow to as thick as 12 inches. The thick covering protects the lower part of the tree from fire damage. Also, most of a redwood's branches and leaves are high up on the tree. This keeps them safe from forest fires. Redwoods are safe from insect damage because the wood has a bitter-tasting chemical.

What should I do?

If you ever get a chance, visit a redwood forest. Look among the tree trunks and imagine who might have camped there a thousand years ago. Look upward and just imagine how high the trees might grow if we protect them.

【1】To see a redwood tree, you should go to _______.

A.the west coast of North America

B.the coast of the Atlantic Ocean

C.South American coast

D.anywhere in the world

【2】What is important for redwoods to grow in dry seasons?

A.Rain fall.B.Sea water.C.Wet air.D.Ocean life.

【3】Redwoods are safe from forest fires because of

A.their tasteB.their chemicalC.their systemsD.their colors

【4】If you want to know how big coast redwoods are, under which question should you look?

A.What's special about redwoods?

B.Where do redwoods grow?

C.Why do redwoods grow there?

D.How do redwoods survive?

【5】What is the author's main purpose for writing this passage?

A.To praise.B.To suggest.C.To introduce.D.To question.
