My parents operated a small restaurant in Seattle.It was open twenty-four hours a day, six days a week.And my first real job,when I was six years old,was 36 the diners’ shoes.My father had done it when he was young,so he taught me 37 to do it efficiently,telling me to 38 to reshine the shoes if the customer wasn’t 39 .
Working in the restaurant was a cause of great 40 because I was also working for the good of the family.But my father 41 that I had to meet certain standards to be part of the team.I 42 to be punctual,hard-working,and polite to the 43 .
I was 44 paid for the work I did at the restaurant.One day I made the mistake of advising Dad that he 45 give me $10 a week.He said,“OK.How about you paying me for three meals a day you have here? And 46 the times you bring in your friends for free soft drinks?” He 47 I owed him about $40 a week.
I remember returning to Seattle after being 48 in the US Army for about two years.I had just been promoted to Captain at that time.And full of pride,I walked into my parents’ restaurant,but the 49 thing Dad said was,“How about your 50 up tonight?” I couldn’t 51 my ears! I am an officer in the Army! But it didn’t 52 as far as Dad was concerned,I was just 53 member of the team.I reached for the mop(拖把).Working for Dad has taught me the devotion to a 54 is above all.It has nothing to do with 55 that team is involved in a family restaurant or the US Army.

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.
