A scientist locked himself in a small air-tig...

A scientist locked himself in a small air-tight plastic tent with 200 plants to see if they could change CO2 into oxygen (氧气) fast enough to keep him alive.

Kurtis Baute locked himself in a 3m by 3m tent in his brother’s backyard in British Columbia, Canada. He hoped to find out if by surrounding himself with plants, the CO2 he breathed out could be changed into oxygen to allow him to survive in the locked tent for at least three days. Unfortunately, he had to give up the experiment after only 15 hours, as CO2 levels reached a dangerous point where he risked suffering brain damage.

“I could probably survive in the tent for three days,” Baute wrote on his website. “But my goal is not to just ‘not die’. My goal is to end this project without developing brain damage or just generally causing lasting harm to my body. But as it turns out, that’s exactly what he risked as the 200 plants he took with him into the tent couldn’t meet his needs. Clearly, a cloudy sky prevented them from receiving all the sunlight they needed to perform photosynthesis (光合作用), so they couldn’t recycle CO2 fast enough.

“Plants are great at taking in CO2 and they love it. Since it wasn’t a bright and sunny day, they weren’t getting the light they needed, which meant CO2 just kept rising. I had to give up the experiment as that continued.” the young experimenter said.

15 hours into the experiment, Baute reached the set danger point and then ended this experiment. Still, he called the experiment a “huge success” as his main goal was actually the terrible effects of climate change and CO2 emissions. “The conclusion about my experiment is that if CO2 is too high, I’ll escape, which is just everyday experiences for many people on this planet. Everyone deserves clean air, but not everyone has it,” he wrote.

1.Why did Kurtis Baute stay in the tent for only 15 hours?

A. The tent is too small for him to stay too long.

B. The environment in the tent is dangerous for him.

C. CO2 in the tent couldn’t be changed into oxygen.

D. He couldn’t survive in the locked tent any longer.

2.What made it hard for the 200 plants to satisfy Kurtis Baute’s needs?

A. His health condition. B. His wrong decision.

C. Too much CO2. D. The cloudy weather.

3.What does Kurtis think of the result of the experiment?

A. Disappointing. B. Surprising.

C. Satisfying. D. Interesting.

4.What may be the best title for the text?

A. A test to show the importance of clean air

B. Surviving in the tent

C. The set danger point

D. Making people know the use of plants

In an effort to discourage people from using plastics, scientists have been hard at work inventing alternative packaging products.

The idea of using seaweed（海草） to make eco-friendly water bottles has been around for a few years. Recently, Ari Jonsson took his invention—a water bottle made from red seaweed—to show off at a festival. The bottles will only hold their shape as long as they are filled. As soon as these bottles are empty they will begin to break down, though they would be perfectly safe to eat. Ari Jonsson's bottles are a step closer to a widely used alternative to the current plastic ones.

The eatable water container is not the only product to add to our image of the future. Narayana Pessapaty has also created eatable spoons. After the success of his spoons, Mr. Pessapaty is ready to expand and introduce forks and chopsticks to his menu. His aim is to largely reduce the amount of plastic waste, which is a huge problem for waste sites all over the world, It is a product that may take up t0 500 years to break down, and recycling companies worldwide are struggling to deal with it.

Aside from the obvious benefits to the environment, this new packaging is also cheap to produce and therefore cheap to buy. Even better is the fact that similar eatable cutlery can be made at home, possibly a science project for children or just fun with friends. Why not experiment and create your own recipes?

1.Why do scientists invent alternative packaging products?

A. To make people's life more convenient.

B. To show off their inventive talents.

C. To change the way we picnic outside.

D. To reduce the amount of plastic waste.

2.What makes Art Jonsson's water bottles eco-friendly?

A. They can be made at home.

B. They are cheap to produce and buy.

C. They will hold their shape when they are filled.

D. They will break down themselves when empty.

3.What do Ari and Narayana's inventions have in common?

A. They are convenient to carry.

B. They are safe to eat.

C. They can be used for a short time.

D. They are heavier than plastics.

4.What can be inferred from this passage?

A. Home-made eatable cutlery is likely to be popular.

B. Eatable cutlery will completely replace plastics in the near future.

C. No recycling companies can break down plastic waste.

D. It's unsafe for individuals to invent eatable cutlery at home.

E

An old sea captain was often seen opening a small locked box, and looking inside. The crew’s curiosity grew and, on the day he retired, they rushed to cut the lock. There they found a sheet of paper that read, “Left—port(左舷). Right--- starboard(右舷).”

Are you afraid to make a mistake? If you made mistakes recently, maybe you need to hear about Roy Riegels.

The story is told about Roy and the 1929 Rose Bowl championship football game between Georgia Tech and the university of California. Shortly before halftime, Roy Riegels made a huge mistake. He got the ball for California and somehow became confused and started running in the wrong direction! One of his teammates tackled(抢断) him after he had run 656 yards, just before he would have scored for the opposing team. Of course, Georgia Tech gained a distinct(明显的) advantage through the error.

After the first half was over, Riegels sat in a corner, put his face in his hands and wept.

Coach Nibbs Price struggled with what to do with Roy. He finally looked at the team and said simply, “Men, the same team that played the first half will start the second.”

All the players except Roy went to the field. Though the coach looked back and called to him again, he remained seated in the corner. Coach Price went to him and said, “Roy, didn’t you hear me?”

“Coach,” he said, “I can’t do it. I’ve ruined you; I’ve ruined the school; I’ve ruined myself.”

But the coach Price put his hand on Riegels’ shoulder and said,” Roy, get up and go on back; the game is only half over.”

Roy Riegels went back and those Tech men will tell you that they have never seen a man play football as well as Roy Riegels played that second half.

The next time you make a mistake, it might be good to remember the ABC method.

A—Acknowledge(admit) your error and accept responsibility for it. Don’t try to fix the blame on other people or circumstances(客观环境). When you fix the blame, you never fix the problem.

B—Be gentle with yourself. The game is only half over. This is not the first mistake you ever made, nor will it be the last. You are still a good and caring person. Besides, later you may laugh at the mistake, so try to lighten up a bit now.

C—Correct it and move on. Correcting mistakes may also mean to amends(弥补过错），if necessary.

Now, go make your mistakes. And if you practice the ABC method, you’ll live to laugh about many of them.

67. The old captain kept a sheet of paper to_____.

A. give his men a lesson

B. arouse his crew’s curiosity

C. prove he was a good captain

D. tell “port” and “starboard” apart

68. From the passage we learn Coach Price______.

A. insisted on replacing Roy

B. decided to punish Roy after the match

C. criticized Roy for his serious mistake

D. encouraged Roy to finish the match

69. How was Riegels’ performance in the second half?

A. Very disappointing  B. Rather excellent  C. Fairly ordinary  D. Quite bad

70. The ABC method_____.

A. advised you to try to forget mistakes

B. helps you deal with mistakes

C. helps find out the causes of mistakes

D. advised you to be strict with yourself.
