It’s impossible to determine how many people would have lost their lives without the contribution of African-American inventor Dr Charles Drew.
Charles Drew was born on June 3, 1904, in Washington, DC. His early interest was in education, but he was also an outstanding athlete. While in college, he was awarded as the man who contributed the most to sports during his four years in school. Drew’s sister Elsie suffered from tuberculosis(肺结核) and died in 1920. Her death influenced his decision to study medicine.
After becoming a doctor and working as a college instructor, Drew went to Columbia University, where he earned his Doctor of Medical Science degree. During this time he became involved in research on blood and blood transfusions.
At Columbia, he wrote a paper on “banked blood”, in which he described a technique he developed for the long-term preservation of blood plasma. Before his discovery, blood could not be stored for more than two days because of the rapid breakdown of red blood cells. Drew had discovered that by separating the plasma from the whole blood and then refrigerating them separately, they could be combined a week later for a blood transfusion. Drew became the first African American to receive a PhD in medical science.
After World War II broke out, Drew was called upon to put his techniques into practice. He was named a project director for the American Red Cross but soon quit his post after the government issued an order that blood taken from white donors should be separated from that of black donors.
On April 1, 1950, after he attended the annual free clinic at the John A. Andrew Memorial Hospital, he and other three physicians decided to drive back home. As he was tired from spending the night before in the operating room, he lost control of his car. Drew was badly injured and was taken to Alamance General Hospital in Burlington, North Carolina. He was pronounced dead half an hour after he first received medical attention. Drew's funeral was held on April 5, 1950, at the Nineteenth Street Baptist Church in Washington, DC.
But contrary to popular thought, he was not refused a blood transfusion by an all-white hospital. He indeed received a transfusion but was beyond the help of the doctors attending to him. As Dr. John Ford, one of the doctors who survived the accident, later explained, “We all received the very best of care. The fact that he was a Black did not in any way limit the care that was given to him.” Over the years, Drew has been considered one of the most honored figures in the medical field.According to the passage, ________ might have contributed to the invention of blood banks.

Shree Bose is one of the most impressive kids graduating from Fort Worth Country Day High School this year. Bose has a large circle of friends, and there’s one who you may have heard of: President Obama. He has twice publicly recognized her achievements in cancer research and spoken with her in the Oval Office.
If that isn’t enough, Bose recently gave a TED Talk about her work with the cancer drug Cisplatin, which also won her first prize at the Google Science Fair and recognition as one of Glamour magazine’s Young Amazing Women of the Year.
After watching her grandfather struggle with liver cancer, Bose was determined to help out in any way she could. As a high school student though, her scientific choices were limited. She reached out to various hospitals and research centers, but doctors turned down her requests because they felt she was too inexperienced medically.
Only the North Texas Science Health Center respected her determination and chose to guide her. The results were amazing.
Bose chose to study a protein (蛋白质) and its reaction with the cancer drug Cisplatin. She noticed that when she prevented this protein from growing, Cisplatin was allowed to begin destroying cancer cells once again.
“My project not only contributes to the understanding of the relationship between the protein and Cisplatin, but also suggests a newer, more effective treatment for patients who resist Cisplatin,” Bose said.
Bose’s achievements aren’t limited to the lab, though. She was also captain of her swim team and editor-in-chief of her school paper.
Bose is currently getting practical experience at the National Institute of Health and she’ll be attending Harvard in the fall. She plans to study molecular biology and go to medical school. Eventually, she would like to be a doctor.President Obama has spoken with Bose because she ______.
| A．gave a TED Talk recently |
| B．is captain of her swim team |

According to Bose’s research, ______ helps make Cisplatin work better.
| A．stopping the protein from growing |
| B．destroying cancer cells timely |
| C．using the drug more frequently |
| D．making the protein react with the drug |
From the passage, we know that _____.
| A．Bose’s research was supported from the start |
| B．Bose plans to become a doctor in the future |
| C．Bose will study in the National Institute of Health |
| D．Bose’s grandfather asked her to do cancer research |
The passage is mainly about _____.
| A．a research on cancer drugs |
| B．a new effective cancer treatment |
| C．a doctor who has a promising future |
| D．a girl who did research on cancer treatment |
Are you a team person? Are you at your best as part of a small, tightly united group of dedicated workers? If so, the future may hold more for you than you think.
High technology, some predicted, would make teamwork a thing of the past. That’s happening in those areas of business and data processing where one person and a computer can replace a team of workers.
But, elsewhere, teamwork is very much alive. High technology has led to a new type of teamwork in a number of fields, including advertising, scientific research, engineering design, architecture and ocean exploration. Through computer networking, scientists, engineers and technicians at different locations--often thousands of miles apart--can work on the same project at once. They can exchange ideas, try out different designs and test their results.
Examples? An engineering team can now design and try out a robot system, a new manufacturing(制造) process, or an entire factory before it is built. An architectural team can do the same with a building or a bridge. A medical team can simulate (模拟) a dangerous operation before performing it on a patient.
Of course, computer-assisted team effort doesn’t end with investigation and simulation. It now usually continues into actual design, manufacturing and testing. “Computer–aided design (CAD) and computer–aided manufacture (CAM) are breaking down barriers between traditional design and manufacturing functions,” explains Dr. Prakash Rao, an engineering manager at General Electric. “Interdisciplinary(跨学科的) teams and engineers follow a product from concept to production. Everything is interconnected like a network.”
Sometimes a computer–aided effort can extend beyond production. A team that produces robots may use them to explore space and ocean depth. For high–technology team work, the future seems limitless.The underlined part “hold more” in paragraph 1 most probably means to .
| A．store more information | B．give more rights |
| C．make more regulations | D．have more chances |
According to the passage, the writer believes that .
| A．the concept of teamwork is still alive and no longer the same as the past |
| B．teamwork will be completely replaced by computers |
| C．teamwork requires more use of computers than that of human beings |
| D．high technology would make teamwork a thing of the past |
The examples given by the writer in Paragraph 4 serve .
| A．to explain his idea of new type of teamwork is reasonable |
| B．to prove high technology has a promising future |
| C．to show that it tends to be an end to teamwork soon |
| D．to indicate the computer--assisted team effort just means investigation . |
Which of the following statements is NOT true according to the passage?
| A．Many fields of science and technology are now using computers effectively. |
| B．No details are given in the passage about barriers between traditional design and manufacturing functions. |
| C．Experts from different fields have to cooperate to develop a product from concept to production. |
| D．CAD and CAM aren’t breaking down barriers between traditional design and manufacturing functions. |

It is really a happy thing to look back on the days I spent with Jennie. We met in night school. After Jennie and I had completed the required courses, we started teaching in the same school. For a time we were just casual friends, but one day, when I was telling Jennie about my problem son, we discovered we were kindred (同类的) spirits. "He’s a difficult little character," I explained. Jennie looked thoughtful. "Maybe you’re only seeing him with your eyes." She was silent for a moment and then added softly, "It is only with the heart that one sees rightly." I stared at her. "You’re quoting (引用) that! It’s from The Little Prince, Saint-Exupery’s book for children, one of my favorites. You know it, too?" Jennie nodded. "I love it. I’ve read it so often. I’ve practically memorized it."
Now, when I think of Jennie, I recall that book because Jennie--more than anyone I know--possessed the gift of seeing with the heart.
From that moment of a treasured book shared, our friendship grew steadily. It wasn’t that I didn’t have an excellent relationship with my husband and son, but my mother had died shortly after my marriage, and I had neither sisters nor daughters. I realize, now, how I needed someone to share those little, seemingly unimportant things that add so much to life--things that must be shared to be fully appreciated.
And it was Jennie who helped me with my fourth-grade problem child. One day I was at my wit’s end. "What he needs is a good beating!" I shouted.
"He’s probably had plenty of those," Jennie said. "Maybe he just needs sincere praise for anything he does right, and a hug or two each day." I followed this suggestion, and eventually, because of Jennie, I discovered a lovable little boy.
Looking back, I have to admit that she taught me so much. The days I spent with her has become one of my happiest memories.What does the underlined part mean in the fourth paragraph?

I was sure that I was to be killed. I became terribly nervous. I felt in my pockets to see if there were any cigarettes, which had escaped their search. I found one and because of my shaking hands, I could hardly get it to my lips. But I had no matches, they had taken those. I looked through the bars at my jailer (狱卒). He did not make eye contact with me. I called out to him “Have you got a light?” He looked at me and came over to light my cigarette. As he came close and lit the cigarette, his eyes absently locked with mine. At that moment, I smiled. I don’t know why I did that. Perhaps it was nervousness, perhaps it was because, when you get very close, one to another, it is very hard not to smile. Anyway, I smiled. I know he didn’t want to, but my smile went through the bars and generated a smile on his lips, too. He lit my cigarette but stayed near, looking at me directly in the eyes and continuing to smile.
I kept smiling at him, now considering him as a person and not just a jailer. “Do you have kids?” he asked. “Yes, here, here.” I took out my wallet and nervously felt the pictures of my family. He, too, took out the pictures of his family and began to talk about his plans and hopes for them. My eyes were filled with tears. I said that I was scared that I’d never see my family again, never have the chance to see them grow up. Tears came to his eyes, too. Suddenly, without another word, he unlocked my cell (牢房) and silently led me out and set me free.
“My life was saved by a smile.” Yes, the smile--the unaffected, unplanned, natural relation between people. I really believed that if that part of you and that part of me could recognize (认可) each other, we wouldn’t be enemies. We couldn’t have hate or scare.The true statement of the following according to the passage is ______.
