1 . On Monday, a lawsuit (诉讼) in the US got huge headlines around the world. It deals with a truly 21st century issue—whether human genes (基因) may be patented.

Myriad Genetics, a biotechnology company, discovered two genes — BRCA 1 and BRCA 2 — that are highly related to breast cancer. Myriad patented its discoveries and a group of researchers challenged that the patent was illegal.

The US patent law protects the temporary economic rewards inventors get from their inventions. But it also says a product of nature or a law of nature can’t be patented. For example, Einstein couldn’t patent on his discovery of E=mc².

And until relatively recently, many of the medical researchers voluntarily gave up patents on their inventions. When Dr. Jonas Salk, the inventor of the polio vaccine (小儿麻痹症疫苗), was asked in 1955 whether he had a patent on the vaccine, he replied, “Could you patent the sun?”

Myriad Genetics, however, says that the genes it identified are not like the sun. It notes that there are 20,000 genes in the human body and that it has sorted through all those genes and found the two that are closely related to breast cancer.

Not so, say those challenging the patent. Human genes are products of nature. They are just a part of the human body. “All Myriad does is take the part out of the body,” says the challengers’ lawyer, Christopher Hansen. “Can the person who first takes the heart out of the body patent on hearts?”

Rochelle Dreyfuss, a patent expert who is not associated with this case, is a little more down to earth. “At some level it is about money,” he says, “because medicine doesn’t happen for free. The patent system is very important to encourage companies to spend more money on scientific research and development.”

Then how do other countries handle this tricky situation? Most countries approve patents on genes, but they also allow other scientists to use the genes freely to do research and develop new medicines and testing methods.

7 . 阅读下面短文，在空白处填入1个适当的单词或括号内单词的正确形式。

In 1951, a young mother of five named Henrietta Lacks visited The Johns Hopkins Hospital. Upon     1     (care) examination, the famous doctor Howard Jones discovered a large cervical tumor (宫颈肿瘤).

A small number of her cancer cells     2     (collect) during a medical test were sent to Dr. George Gey’s nearby lab. For years, Dr. Gey, a well-known cancer and virus researcher, had been collecting cells from all patients     3     came to The Johns Hopkins Hospital with cervical cancer, regardless of     4     (they) race or socioeconomic position, but each cell    5     (rapid) died in Dr. Gey’s lab. What Dr. Gey soon discovered     6     (be) that Mrs. Lacks’ cells were unlike any of the others he had ever seen: where other cells would die, Mrs. Lacks’ cells doubled every 20 to 24 hours.

Today, these incredible cells, named “HeLa” cells, are used for     7     (study) the effects of drugs and viruses       8     the growth of cancer cells without experimenting on humans. Scientists use “HeLa” cells to test the effects of radiation (辐射), to study the human genome, and to learn more about how viruses work. These cells also played     9     important role in the     10     (develop) of the polio vaccine (小儿麻痹症疫苗).

10 . A medical emergency can happen anywhere at any time. Taking a brief moment to seek help is often the best first response. But before an ambulance can get to the scene, the immediate first aid attendance to anyone who is injured seriously makes a difference between life and death. Life Saver Team has been providing CPR (心肺复苏术) and first aid training since 2009. Here are a few of their most popular courses:

CPR AED

It is a classroom video-based, instructor-led course that teaches the basic techniques of CPR and the use of an AED (自动体外除颤器), as well as how to relieve choking. This course teaches skills with research proven techniques.

●Course length: 2 hours

●Price: $50 (Sign up for a first aid course for an additional $30)

Upon completion of this course, students will receive an American Heart Association Heart Saver Fist Aid Course Completion Card that is valid (有效的) for two years.

Basic Life Support

This is a classroom course designed to provide a wide variety of healthcare professionals with the ability to recognize several life-threatening emergencies, provide CPR, and relieve choking in a timely and effective manner.

●Course length: 4 hours

●Price: $60 (Sign up for a first aid course for an additional $30)

The American Heart Association BLS for Healthcare Provider Course Completion Card is valid for two years.

First Aid

It is a classroom, video-based, instructor-led course that teaches students critical skills to manage an emergency in the first few minutes until emergency medical services arrive. Students learn skills such as how to treat bleeding, broken bones and other first aid emergencies.

●Course length: 2 hours

●Price: $45

Upon completion of this course, students will receive an American Heart Association Heart Saver CPR AED Course Completion Card that is valid for two years.
