An annoying problem for humans, who like to boast (夸耀) about all the distant planets and moons we have explored, is that we've never taken a good look right under our noses.The inside of the earth is relatively close but how can we get there?

The deepest oil well enters a mere six miles into the crust (地殼)  (the center of the earth is about 4,000 miles deeper).Russian scientists dug the deepest hole in Siberia," but bottomed out at about 7.5 miles below the surface.The Mohole project, a U.S.plan in the 1950s, called for drilling a hole 25 miles down to the boundary be??tween the hard rocks of the crust and the soft mantle (地幔).Sadly the project involved govern??ment supporting.

It gets harder and harder to drill deep into the earth because rocks get softer and softer. Hard but easily broken at the surface, rocks become plastic at depth, and the pressure caused by the weight of the overlaying crust — about 52,800 pounds per square inch at a depth of ten miles, makes further drilling impossible.

What little we know about the inside of the earth (like the fact that there' s a crust, a mantle, and a core) comes from indirect evidence, such as the analysis of earthquakes.

So maybe it' s time for a thorough new method to explore the earth's inside.Scientist David Stevenson says we should forget about drilling holes.Instead, we should open a crack (裂縫). 

Stevenson suggests digging a crack about a half mile long, a yard wide, and a half mile deep (not with a shovel) but with an explosion on the scale of a nuclear bomb.Next, he'd pour a few hundred thousand tons of molten (融化的) iron into the crack, along with a robot.The iron, thicker than the surrounding crust, would move downward at about 16 feet per second, carrying the robot with it and opening the crack deeper and deeper.The iron mass would drop for about a week and 2,000 miles to the outer edge of the earth core, the robot sending out data to the sur??face.

Stevenson compares his idea to space explo??ration."We're going somewhere we haven't been before," he says."In all possibility, there will be surprises."

This idea can probably be put in.the drawer marked with Isn't Going To Happen.The robot would have to survive temperatures that would melt pretty much anything.But Stevenson's idea may inspire a new look at an old problem.Great things can come from what seems like impossible ideas.

Going inside the earth is ________ than going into space.

A.more interesting B.more possible    C.easier            D.more challenging

How deep have we gone into the earth until now?

A.6 miles.         B.4,000 miles. C.7.5 miles.        D.25 miles.

Which of the following is TRUE about David Stevenson's idea?

A.It is an inspiring but not practical idea now.

B.It is a practical proposal that has come into use now.

C.It is a good proposal that will soon be put into practice.

D.It is a false theory that cannot be carried out at all.

What might be the most suitable title for the text?

A.An Annoying Problem for Humans

B.To the Center of the Earth

C.The Mohole Project

D.David Stevenson' s Proposal

The history of modern art begins with Impressionism, a movement started in Paris in the mid-1800’s. At that time many artists painted in a very traditional way that involved spending hours in a studio, painstakingly (辛苦地) creating paintings that were extremely detailed. These paintings were sometimes of people or landscapes or historical events. In 1863, Edouard Manet exhibited his painting “Dejeuner sur l’erbe” at the Salon des Refuses. The painting caused a commotion (騷動(dòng)), thus starting the Impressionist movement. Although Edouard Manet is the declared leader and founder of the group, he was not present at the first group exhibition or any of the other eight collective Impressionist shows. The movement gained more attention in the April of 1874 when Claude Monet, Auguste Renoir, Alfred Sisley, and Jean-Frédéric Bazille formed Society of Artists, Painters, Sculptors, Engravers and began exhibiting outside of the official salon. The same year, the term Impressionism was invented by criticizing (批評(píng)的) journalist Louis Leroy to describe their paintings, who worked for the magazine Le Charivari.
The Impressionists often paint out of doors and want to show how light and shadow fall on objects at particular times of the day. Their works are sometimes described as “captured moments” and are characterized by short quick brushstrokes (筆) of colour which, when viewed up close looks quite messy and unreal. If we step back from the Impressionist paintings, the colours are blended together by our eyes and we are able to see the painters’ subjects which often show colourful landscapes, sunlight on water as well as people busy with outdoor activities.
【小題1】Before Impressionism, the works of artists were         .

A.quite abstractB.very confusing
C.very detailed D.quite controversial
【小題2】Who first started Impressionism? ___________
A.Claude Monet.B.Edouard Manet.
C.Auguste Renoir.D.Alfred Sisley.
【小題3】 The works of the Impressionists are best viewed         .
A.with imagination B.a(chǎn)t a distance
C.outdoors D.in a studio
【小題4】The second paragraph is mainly about ______.
A.the painting style of the Impressionists
B.how to describe the Impressionist paintings

Her name may be 501, but she’s more than just a number. The lovely sea otter(水獺) is the star of Otter 501, a new film from Sea Studios Foundation.

Otter 501 was just a few days old when she lost her parents in June 2010. Washed onto a beach along California’s Big Sur coast, the pup(幼崽) could have died. Instead, she got a second chance at life after being taken to an aquarium(水族館). There she learned from an adoptive otter mom how to be an otter. In the film, it’s Katie Pofahl who finds the troubled pup on the shore. Through the young volunteer’s eyes, we follow 501’s journey from the day of her rescue to her release into the wild in Elkhorn Slough. But while the fluffy star’s story has a happy ending, the film reminds us of the threats that remain against California’s sea otters.

Mark Shelley is the executive director of Sea Studios and producer of Otter 501. He hopes the movie will encourage more young people to get involved in protecting the otter’s ocean habitat. Time For Kids (TFK) spoke with Shelley and Pofahl about sharing the otter’s tale.

TFK:      How much of the film is fact, and how much is fiction?

Shelley:   The story of 501 and the explanation of the natural history of the sea otter are fact. But we needed a good storyteller to tell the story. That’s where Katie Pofahl’s character came in. Katie’s story in the film is partly fictionalized. She is a trained biologist from the Midwest who moved out here, like her character, so all that is true. She wasn’t really a volunteer at the aquarium, but she did go through the training for the film.

Pofahl:    I was one of the last people to get involved in the project. Mark and Sea Studios put out a casting call for a marine biologist. I responded with a little video, and the team liked it. So, I was brought on to help tell 501’s story.

TFK:       What did you learn about otters during filming that you didn’t know before?

Pofahl:    I’m a zoologist, and I love studying animals. I came onto this project thinking that I knew almost everything there was to know about otters. But I learned some things. Otters keep busy because they live in such cold waters. Unlike other marine mammals, they do not have blubber(鯨油,鯨脂) to keep warm. So, they are constantly moving and eating. And they are a keystone(基本的) species, which means they help to structure the environment they live in. There are endless things to learn. That’s what I love about this job.

TFK:       What do you hope people will take away from the film?

Pofahl:    We have an amazing opportunity to help people become aware of how they impact the world. People will watch the movie to see this lovely otter, but it can also be an entry point into conservation. We want to show people that these animals are amazing and that they are at risk and that they are worth protecting. We also want to show people, especially young women, anyone can get involved in science. It’s been an amazing experience for me.

59. We can conclude from the text that sea otters ________.

A. prefer to live in warm ocean waters

B. stay quiet most of the time and don’t eat much

C. are a dangerous species faced with extinction(滅絕)

D. are a key element in the marine life environment

60. Which of the following statements about the film Otter 501 is TRUE according to the text?

A. The film is about the tragic story of an otter that lost its parents.

B. The character of Katie Pofahl is based completely on a real life person.

C. The director of the film is worried about the trouble faced by California’s sea otters.

D. The movie was shot to raise awareness about the natural history of otters.

61. Which of the following is the right order of events?

a. Otter 501 got an adoptive otter mom at the aquarium.

b. Otter 501 was rescued at the Big Sur coast.

c. Otter 501 lost its parents.

d. Katie Pofahl got involved in the project of Otter 501.

e. Otter 501 was released into the wild in Elkhorn Slough.

A. c-d-b-a-e                 B. b-c-a-e-d                  C. c-b-a-d-e                D. b-a-c-e-d
