4 . In April 2018, a group of Canadian scientists flying in a helicopter (直升飞机) discovered something they didn't expect to see — a huge, unknown cave with an opening the size of a football field.

The cave was discovered in the northern part of Wells Gray Provincial Park, in a wild, faraway area of Canada's Cariboo Mountains. The area is hard to get to and even harder to travel through. It is covered with snow for much of the year.   

The group told Catherine Hickson, a scientist who studies rocks, about the cave. Dr. Hickson got a team of researchers together to study it. In September, they went for a closer look after most of the snow melted (融化). The cave is one of the largest in Canada. Not only is the opening to the cave larger than a football field, the cave is also deep. The team couldn't measure (测量) all the way to the bottom, but they think it may be more than 180 meters deep. The cave is tens of thousands of years old. But the rock in the cave is made of used to be at the bottom of an ocean (海洋). It is hundreds of millions of years old.

A small, but fast river of melting snow leads into the cave on one side, creating a waterfall near the top and a river at the bottom. The water comes out again a long way away. The exit (出口) is about 2.1 kilometers away and about l/2 kilometer lower down.

The cave will have to wait to get an official name. For now, the cave is being called "Sarlacc's Pit "because it looks similar to the home of the Sarlacc, a person in the Star Wars movie Return of the Jedi.

For Dr. Hickson, there's a lesson to be learned from the cave. "It shows you that you don't know everything, "she says." There are things yet to be discovered."

1. Why did the cave remain unknown in the past?

A．It is in a wild mountain area.	B．It has been there for just a few years.
C．Its opening is too small to be noticed.	D．The weather there is cold all year round.

2. What are Paragraphs 4 and 5 mainly about?

A．The history of the cave.	B．Some facts about the cave.
C．The value of studying the cave.	D．The methods of studying the cave.

3. What does the underlined word "It" in Paragraph 4 refer to?

A．The snow.

B．The river.

C．The ocean.

D．The rock.

4. The cave's name "Sarlace's Pit" has something to do with ________.

A．local culture

5 . An ancient tomb was recently discovered in southern Siberia in which there may be treasure, priceless objects, and the 3, 000-year-old remains of an ice mummy.

Swiss scientist Gino Caspari with the University of Bern was looking carefully at the pictures of the area in the Russian Tuva Republic, when he came across what appeared to be a tomb. It is a tomb of the Scythians, an ancient group of Eurasians.

This summer, together with researchers from the Russian Academy of Sciences and the Hermitage Museum, a dig at the site not only proved Caspari's idea, but told us the site is the largest and oldest of its kind ever discovered in what's increasingly known as the “Siberian Valley of the Kings.”

While any discovery dating back to a period between the Iron Age and Bronze Age is exciting, it's the nature of this site that makes scientists want to begin carefully clearing away the layers of rock and earth. First, the tomb appears to have never been dug, because it is in a Siberian wetland faraway from the nearest place where people live. Second, and most important, is its possible resting place under a thick layer of permafrost.

“There's permafrost in the area,” Caspari said. “There are really only a handful of permafrost tombs and very few that have not been damaged, where there have been ice mummies in good condition, and all the things in the tomb are untouched.”

While not as large, other tombs discovered in the area have produced fantastical treasures and objects, including thousands of gold objects and other things about the past. By studying all these tombs, researchers hope to have a better understanding of the Scythian people.

Caspari said his team is in a race against time to uncover the tomb and find out its secrets. “We now have to act fast,” he said, “because with the rising temperatures, the permafrost could melt and damage all the things in that tomb. And these are things that are over 3,000 years old, that look like new, like they were put there yesterday.”

1. How did Caspari discover the tomb?

A．By studying pictures.	B．By visiting a Russian area.
C．By talking with Russian researchers.	D．By comparing other scientists, ideas.

2. Why has the tomb remained untouched?

A．It is covered by a lot of rocks.	B．It is well kept by the Scythians.
C．It is too small to draw attention.	D．It is hidden in a wild cold place.

3. Why do scientists want to uncover the tomb?

A．To better protect the tomb.	B．To save the treasures inside.
C．To learn more about the Scythians.	D．To have a good understanding of mummies.

4. Why is Caspari's team racing against time to dig the tomb?

A．The tomb is too old.	B．It is getting hotter and hotter.
C．Some treasures are being damaged.	D．They want to save time for other tombs.
