A team of researchers has found that immunizing patients with bee venom instead of with the bees' crushed bodies can better prevent serious and sometimes fatal sting reactions in the more than one million Americans who are hypersensitive to bee stings. The crushed-body treatment has been standard for fifty years, but a report released recently said that it was ineffective. The serum made from the crushed bodies of bees produced more adverse reactions than the injections of the venom did.
The research compared results of the crushed-body treatment with results of immunotherapy that used insect venom and also with results of a placebo. After six to ten weeks of immunization, allergic reactions to stings occurred in seven of twelve patients treated with the placebo, seven of twelve treated with crushed body extract, and one of eighteen treated with the venom.
The word "fatal" in paragraph 1, sentence 1 is closest in meaning to ______.

听力原文： When I was walking down the street the other day, I happened to notice a small brown leather wallet lying on the sidewalk. I picked it up and opened it to see if I could find out the owner's name. There was nothing in side it except some change and an old photograph -- a picture of a woman and a young girl about twelve years old, who looked like the woman's daughter. I put the photograph back and' took the wallet to the police station. That evening I went to have dinner with my aunt and uncle. They had also invited a young woman so that there would be four people at the table. Her face was familiar. I was quite sure that we had not met before, but I couldn't remember where I had seen her. In the course of the conversation, however, the young woman happened to mention that she had lost her wallet that afternoon. All at once I realized where I had seen her. She was the young girl in the photograph, although she was now much older. She was very surprised, of course, when I was able to describe her wallet to her. Then I explained that I had recognized her from the photograph I had found in the wallet. My uncle insisted on going to the police station immediately to claim the wallet. As the-police sergeant handed it over. he said that it was amazing that I had not only found the wallet, but also the person who had lost it.
