It has often been said that a person’s life is the sum total of their experiences. That seems like a simple ________,but if one accepts this, then why do so many of us engage in practices and activities which are negative and actually ________ us?

________ the family of four who decided to each clean a different area. They each took a sponge(海绵), did the ________ , and then placed them back in the kitchen.

A visitor came along who was ________about what was cleaned in the home, but couldn’t tell by ________since the sponges all looked the same. So, in order to ________ his curiosity, he decided to squeeze each sponge to see what came out.

When the first sponge was squeezed, some cola came out, so the visitor ________ someone cleaned the kitchen with that one. Upon squeezing the second, he found motor oil, so________ , someone was cleaning the garage. In the third, baby powder came out when it was squeezed, which________that the baby’s nursery was done. And ________ ,in the last one was wax, which was ________ on the floor.

As the visitor laid the last sponge down, he again remarked on their similarity. They all looked the same ________ they were squeezed.

Walk through the Amazon rainforest today and you will find it steamy, warm, damp and thick. But if you had been there around 15,000 years ago, during the last ice age, would it have been the same? For more than 30 years, scientists have been arguing about how rainforests might have reacted to the cold, dry climate of the ice ages, but till now, no one has reached a satisfying answer.

Rainforests like the Amazon are important for mopping up CO2 from the atmosphere and helping to solve global warming. Currently the trees in the Amazon take in around 500 million tons of CO2 each year: equal to the total amount of CO2 given off in the UK each year. But how will the Amazon react to the future climate change? If it gets drier, will it survive and continue to draw down CO2? Scientists hope that they will be able to learn in advance how the rainforest will manage in the future by understanding how rainforests reacted to climate change in the past.

Unfortunately, collecting information is incredibly difficult. To study the past climate, scientists need to look at fossilized pollen(花粉)kept in lake mud, Going back to the last ice age means drilling down into lake sediments(沉淀物), which requires specialized equipment and heavy machinery. There are very few roads and paths, or places to land helicopters and aeroplanes. Rivers tend to be the easiest way to enter the forest, but this still leaves vast areas between the rivers completely unsampled(未取样). So far, only a handful of cores have been drilled that go back to the last ice age and none of them provide enough information to prove how the Amazon forest reacts to climate change.

1.How do scientists study the past climate change?

A. By predicting the climate change in the future.

B. By drilling down deep into land sediments.

C. By analyzing fossilized pollen in lake mud.

D. By taking samples from rivers in the Amazon.

2.Why is it difficult to collect information about the past climate change?

A. Because scientists can't find proper equipment and machinery.

B. Because it is very difficult to obtain complete samples.

C. Because helicopters and aeroplanes have no place to land.

D. Because none of the cores provide any information.

3.Where is the passage most probably taken from?

A. A medical journal. B. A news report

C. A travel brochure. D. A science magazine.

4.The best title for the text may be .

A. Secrets of the Rainforest

B. Climates of the Amazon

C. The History of the Rainforest

D. Changes of the Rainforest

As I grew older, my dad and I grew further apart. We always had totally different opinions. He thought that college was a waste of time, but for me it was important to finish college. He wanted me to work my way to the top as he had done in his field, but I wanted a different life. There was a time when we did not talk with each other.

A few months ago, I heard that my 84-year-old dad was in poor health. When he called and asked whether I could move from Colorado back to Tennessee to help him, I knew he was seriously ill. I am his only child and so it was time to meet my father’s requirement.

Two weeks after moving back, we bought a boat and started fishing again. Fishing was one of the few things that we did while I was young and that we both enjoyed. It is strange but true that as we are fishing we are able to put things that have kept us apart for so many years behind us. We are able to talk about things that we have never talked about before. Fishing has been healing the old wounds that have kept us apart.

It is not important how many fish we catch. It is about enjoying the relationship that we have not had for years. I’m 62 and he is 84. When we are on the lake fishing, it is like enjoying life. It is far better to find a way to put the unhappy past behind. I am so lucky to spend the happy time with my father in his last years. Now my heart is filled with love. A smile always graces my lips.

1.The author and his father became further apart because .

A.they lived very far from each other

B.they seldom saw each other

C.they only communicated by phone

D.they had different views on things

3.Which of the following can be the best title for the text?

A.Fishing Brings Us Together

B.Forgiving I s Difficult

C.Memories of Old Days

D.My Beloved Father

While astronauts in space get to do many exciting things, they miss out on ordinary things that we all take for granted-being able to walk on firm ground, hanging out with family and digging into a slice of hot steaming pizza. Though not much can be done about the first two things, there may soon be a solution to the third one, thanks to this cool 3-D pizza printer!

About a year ago, NASA offered $125,000 to Anjan Contractor, a 3-D technology expert, to build a device(设备)that would allow astronauts to make pizza on demand. The mechanical engineer promised that his invention would produce pies in large quantities that looked, tasted and even smelled like pizza made in common ovens.

Late last year, the engineer presented a video of his first prototype(原型)that begins by creating a single slice of dough(面团)that is cooked and printed at the same time. Then comes the tomato “sauce” —a mix of tomato powder, oil and water and finally, a protein slice that resembles cheese. While the video doesn’t show the baking process, the inventor says that once the pizza is printed, it can be ready to be consumed in 7 seconds.

While the pie in the video looks delicious enough to attract any pizza lover, Anjan Contractor is far from ready for astronauts. That’s because he still has to find a solution to make the food container in the printer last for 30 years. Though that may sound unrealistic, actually it is not.

Anjan Contractor believes that the only way that is possible is that the water is removed from all the ingredients(配料)and then they are reduced to the powder form. This, as you can imagine, will not be so easy. But, while the printer may not be ready for space, it certainly looks ready enough for people on earth. Hopefully, NASA and Contractor will consider selling it to those not fortunate enough to go to Mars!

1.Why does the author mention the things that astronauts in space cannot do?

A.To ask us not to take common things for granted.

B.To show they live a difficult life there.

C.To show their life is boring in space.

D.To introduce the topic of the text.

2.NASA offered $125,000 to Anjan Contractor mainly to __________.

A.create some new type of 3-D printer

B.attract more companies to work for NASA

C.help astronauts in space enjoy fresh pizza one day

D.produce pizza in large quantities to earn great profits

3.The biggest challenge that Anjan Contractor is faced with now is probably that __________.

A.he has no money left to go on with his research

B.the pizza doesn’t seem appetizing to pizza lovers

C.he has no way to make pizza that can last for thirty years

D.he cannot make the food container last for decades

4.What’s the best title of the passage?

A.NASA is trying its best to help astronauts eat better

B.Astronauts may soon be able to enjoy steaming hot pizza

C.NASA is working on making pizza for common people

D.A 3-D pizza printer has been used to make pizza

New data from NASA's Curiosity rover indicate Mars Crater once held an enormous lake. This discovery suggests that the red planet may have been much wetter than scientists thought and raises the possibility that the planet was once habitable.

“The size of the lake and the length of time and series that water was showing up implies that there may have been sufficient time for life to develop.” NASA's Mars Exploration Program scientist Dr. Michael Meyer told Reuters.

Curiosity collected the new data on its five-mile drive to Mount Sharp, the prime destination on its mission to study Mars' climate and geography. The rover landed in Gale Crater in August 2012.

After reaching Mount Sharp in September, the rover spent two months studying rocks at the base of the three-mile-high mountain, discovering fine layers of mudstone--which tend to collect at the bottom of lakes. This shows how a mountain inside a Mars' Gale Crater might have formed.

“If our assumption for Mount Sharp holds up, it challenges the idea that warm and wet conditions were passing, local, or only underground on Mars,” Dr. Ashwin Vasavada said in a written statement. “A more radical explanation is that Mars' ancient, thicker atmosphere raised temperatures above freezing globally, but so far we don't know how the atmosphere did that.”

Vasavada said Curiosity will continue to study changes in the rock formation as it climbs Mount Sharp in the next few months, which should test the team's hypothesis.

“We'll also look at the chemistry of the rocks to see if the water that was once present would've been of the kind that could support microbial life, if it ever was present,” he said in a video released by NASA. “With only 30 vertical feet of the mountain behind us, we're sure there's a lot more to discover.”

1.What does this text mainly talk about?

A. How scientists explored Mars.

B. The ways Curiosity used to explore Mount Sharp.

C. Some data about Gale Crater.

D. The discovery of Curiosity rover on Mars.

2.The discovery of the lake proves that _____.

A. early Mars was ripe and ready for life

B. the climate on early Mars was hot

C. life once existed on Mars

D. humans can live on Mars

3. What is the height of Mount Sharp?

A. 5 miles B. 30 miles C. 3 miles D. 22miles

4.Where does this text probably come from?

A. A science fiction. B. A science report.

C. An environment report. D. An official announcement.
