1 . There have been so many improvements in detecting cancer from blood tests to virtual devices that can detect tumors(瘤) painlessly. Now, a new visual technology will allow doctors to detect skin cancers in just 10 seconds.

Researchers from Tel Aviv University (TAU) have come up with a new visual technology that can find out skin cancer without ever cutting into the patient’s body. Skin cancer detection has always been a long process of doing a traditional examination of harmful changes and then waiting for the results. But this new method is so fast that you can know the results instantly.

Early detection of melanomas (a kind of tumors) can save lives according to the researchers. If a melanoma is detected early, and removed right away, the chances for a full recovery are very good. This new technology is built upon the knowledge that harmful changes give off different colors when placed under special light that shows if they are fatal (致命的)and what type of cancer is present. Instead of removing the harmful changes for examination, the research team pioneered a way to check them on the body.

The research was published in the journal Medical Physics, saying the optical technology was tested on 90 patients and it accurately identified the 5 patients with melanoma and 10 with other skin cancers. In addition, 75 other patients that had harmful changes were correctly identified as cancer-free.

The next stage involves testing the technology on many more patients in the hope that it can be used to create an easy-to-use machine that will be able to find out harmful changes on a screen. The visual technology will have the potential to cause an immense change in the field of detecting and treating skin cancer, which increases survivability and the quality of life.

5 . Be it the flu or the coronavirus (冠状病毒), we can all take one basic step to keep ourselves healthy--wash our hands regularly. But how _________ would you be to know that the practice of handwashing was not always around? We can thank a_________   for this important practice: physician Ignaz Semmelweis.

It was 1846     _________   no one knew germs (病菌) existed. Semmelweis worked at the Vienna General Hospital _________ two parts.The hospital’s ward was so large that doctors and midwives (助产士) divided it in half. At the time, there was a major_________ in the ward.   Many of the patients contracted (感染) childbed fever, a   _________   disease, after giving birth.

While looking after the women, Semmelweis noticed something___________   The women in the doctors’ ward were more likely to catch the fever than the women__________   by the midwives. Semmelweis also knew that the doctors worked in the ward before operating_________ the women. Semmelweis came up with a theory: the doctors__________ the women with dirty particles (微粒) from dead bodies! To test his theory, he _________ doctors to wash their hands with chlorine (氯) before going to the ward.   The rate of death _________ significantly.

________ , the practice of washing hands did not become widespread.   Semmelweis’ theory could not explain why women who gave birth outside of hospitals still contracted childbed fever. Many doctors _________   to believe that they were “responsible” for the disease. As a result, the medical community cast doubt on the practice of washing hands.

Handwashing was finally officially adopted in the 1980s by the United States Centers for Disease Control and Prevention. They_________   handwashing as an important factor in preventing the spread of infections. Despite this, handwashing is only performed one-third to half as often as it should be.

10 . Have you ever had cataracts (白内障) removed? Then you may see a bit more clearly due to the achievements made by Dr. Patricia Bath. She was born on November 4, 1942 in the Harlem neighborhood of New York City. Different from girls of her time, she was fond of science as a young girl and greatly contributed to a cancer study while in high school. After earning a bachelor’s degree from Hunter College in New York City in 1964, Bath attended Howard University College of Medicine in Washington, D.C. and got a medical degree there in 1968.

After graduating from Howard University, Bath worked at Harlem Hospital; later she noticed that in her neighborhood, people leading a hard life suffered from blindness that could have been prevented. From then on, Bath determined to create a new field called “community ophthalmology (眼科学)”. It aims to offer eye care to patients who have a hard time gaining regular eye care. Volunteers are trained to examine patients in senior centers or day care programs to test for serious eye conditions and to do vision (视力) testing. Community ophthalmology led to Bath and two others founding the non-profit American Institute for the Prevention of Blindness in 1976. The purpose of the organization is to protect, preserve and restore the sight of patients all over the world.

Bath’s work with patients with cataracts inspired her to develop a new surgical technique. Cataracts are cloudy things on the eyes that, if not removed, will lead to blindness. Bath wanted to use lasers (激光) to remove them, but the technology did not exist at that time. She spent almost five years researching and developing the technique and equipment. Because of that, Bath earned a medical patent in 1988. Her technique of using lasers to remove cataracts has improved and restored the vision of millions of patients around the world.

1. What do we know about Bath from the first paragraph?

A．She showed interest in science.	B．She treated a lot of cancer patients
C．She received no formal education.	D．She failed to get along with others.

2. What is the goal of “community ophthalmology”?

A．To train volunteers to do vision testing.

B．To raise people’s awareness of eye care.

C．To help patients lacking access to regular eye care.

D．To protect and restore the sight of patients worldwide.

3. Why did Bath receive a medical patent in 1988?

A．Because she established community ophthalmology.

B．Because she suggested new ideas of protecting eyes.

C．Because she applied lasers to the removal of cataracts.

D．Because she helped all the blind people see clearly.

4. What is the main idea of the text?

A．Bath’s dream of becoming a scientist.

B．A new method to cure all the blindness.

C．The start of community ophthalmology.
