  They say there are three ways to experience the Grand Canyon; on foot, on mules(骡子)or by air.We chose the first.Up early; my husband and I and our three children couldn’t wait to get started.We decided to walk along a lovely path named Bright Angel Trail.

  As we set out, I was shocked at how narrow the path was.And I couldn’t help noticing that the other tourists weren’t like us.They had heavy backpacks, water bottles, and hats.But as usual we were dressed, As the sun rose higher, Arizona’s famous heat seemed to roast(烘烤)us.There was no shade and our legs were aching.We decided to go back, with the girl on my back and the boys far behind.By the time we finally got back, our legs were like jelly.

  The next day, after we’d had a long rest and a good breakfast, we were ready for another view of the Canyon-by air.After our last walk, this would be the easiest thing in the world.

  We called to each other excitedly as the plane took off and circled around the Canyon.But the smiles on our faces disappeared as the pilot tossed(翻转)the plane around, pretending he was going to hit the ground.I shouted, “STOP, TAKE US BACK!” When we finally arrived back on land, once again our legs were like jelly.We hardly spoke as we drove back.

  As I said, there are three ways to view the Grand Canyon.We never tried the mules, but personally I’d suggest a fourth:buy yourself a good magazine like National Geographic.That way, you can see the Canyon, without fear or tiredness.

Scientists have not come close to understanding all the different kinds of life on the planet, but US researcher Craig Venter is already working on creating the first artificial(人造的)life.

Venter and his researchers made a breakthrough late last month, They successfully moved the DNA of one type of bacteria(细菌) to a yeast cell(酵母), changed it, then put it into another bacterial cell.

“Bacteria have systems that protect them from foreign DNA” Venter explained to the BBC, In the experiment, the team managed to block this system.

The experiment was performed on a simple type of bacteria celled mycoplasma mycoides. The team took the bacteria’s genes and put them into a yeast cell.

Putting a DNA in a yeast cell allowed the team to change the genes in this case, taking out a gene that was not necessary for the bacteria to live.   

They then put the gene into a host bacteria cell. The cell went on to divide normally, producing new healthy bacteria.

In January, the team created artificial genes of a new type of bacteria. Their next goal is to put the artificial DNA into a host cell to create a new species, according to a report in Science magazine.

“lf we don’t make any errors, I think it should work and we should have the first artificial species by the end of the year.” Venter said in the report.

The first artificial life form is likely to be a simple man-made bacteria, to prove that the technology can work.. But that form will be followed by more complex bacteria that turn coal into cleaner natural gas, or algae  that can take in carbon dioxide and change it into fuel.

Many scientists think it’s good news to have this artificial life, but others are worried that the technology to create new organisms might end up in the wrong hands, with dangerous result.

57.Which of the following is true according to the text ?

A  Bacteria have systems that protect them from yeast cell.

B  If we put a gene into a host bacteria cell,the cell will not go on to divide as usual.

C  Venter and his researchers completely achieved all their goals.

D  All the scientists didn’t agree to this artificial life.

58. What can we learn from the underlined sentences?

A. Venter and his researchers had succeeded in this project.

B. Venter predicted that they would make errors in the future,so he decided to give it up.

C. Venter would go on the study and he was full of confidence.

D. Venter was a clearer man but a little shy.

59. Which of the following shows the order of the passage ?

1.change the genes

2. put the gene into a host bacteria cell

3. moved the DNA of one type of bacteria to a yeast cell

4. The cell went on to divide normally

5. put it into another bacteria cell

A. 3-5-1-4-2     .               B. 3-5-1-2-4   C. 4-2-5-1-3                      D. 2-3-5-1-4

60.What will be mentioned in the next paragraph?

A. The wrong hands that created by the artificial life.

B. The advantages and disadvantages about the artificial life.

C. The future about this project.

D. The author’s attitude.
