The poisonous domoic (藻) acid affected Alfred Hitchcock' s "The Birds" after hundreds of them absorbed the poison in the summer of 1961 and lost their minds.
The sick birds likely consumed poisonous acid via small fish. It also tends to collect in shellfish. And, according to a study published Tuesday, it may become more common as oceans warm, threatening birds and humans alike.
Researchers have studied the rate of poisonous acid over the past 20 years in the Pacific Northwest, and found it strongly related to water temperatures that are warmer than normal.
For now, warmer waters typically comes from events like EL Nino and a decades -long climate cycle called "Pacific decadal oscillation," the study found. It isn't yet clear how climate change, which also warms the oceans, might affect the rate of the poison.
"When water's unusually warm off our coast, it's because the circulation and patterns in the atmosphere has changed, bringing warm water from elsewhere - and this is happening at the same time that we also see high poisonous acid in shellfish, " Morgaine McKibben, the study ' s lead author said.
The poison is produced during warm domoic blooms, and gets passed up the food chain by animals that eat it. Sea lions, dolphins and humans are at risk. While some animals can eventually clean themselves of the poison, the threat can last a long time after the warm water decreases.
Animals poisoned by poisonous acid tend to become weak, and experience death. Symptoms in humans include headache, confusion, loss of short - term memory, weakness and unconsciousness.
It isn't just a health risk. An Oregon State University statement notes that officials have to shut down shellfish harvests when poisonous acid levels are high, causing economic harm.
Since health officials first regarded poison acid as a health threat in 1987, Pacific Northwest shellfish harvests have been stopped in 2005, 2017, and 2018. The West Coast crab（蟹）industry took an estimated$100 million hit in 2017 alone.

C. When climate has changed, the oceans get colder.
D. When water becomes warmer, high poisonous acid appears.
3.What result will poisonous acid cause to humans?
A. Making humans conscious. B. Making humans dead.

4.What's the best title of this passage?

The palm - forward (掌心向外) "V" sign, formed by raising and spreading the wrist two fingers, has three different meanings in American culture.
The most popular meaning of the "V" sign was invented in 1941 by a Belgian, Victor De Lavalaye. Wanting a symbol for resistance to the Nazi occupation, he came up with the single letter "V", which stood not only for his own first name, but also for English victory, Flemish virijheid, and French victoire. The symbolism of the sign spread very quickly, and Winston Churchill used it constantly in public appearance. Thus throughout the 1940s and 1950s, the gesture meant simply" victory " .
The second meaning came in the 1960s. Because of its military implication, American antiwar protestors used the sign sarcastically (讽刺地) against the arms, so that it became known as the "peace sign". In the 1970s, the "W' sign, which had lost its military implication, was a common greeting among freedom lovers , acid heads, political radicals, and ultimately, young people in general. So by about the middle of the 1970s, it no longer gave clue to the user's philosophy.
The third meaning is the oldest and least common. American children jokingly put " V" , which resembles "horns", behind friends-heads in group snapshot. They are unknowingly reproducing something that southern Europeans would find highly offensive. This mischief, called "horns of the Devil", is a variant of the European "horns" gesture, which is obscene （猥亵的). Here the "w' sign means "Your wife has been cheating on you or, when placed behind another's head, his wife has been cheating on him. "
In the United States, the gesture is typically given with the palm facing the viewer. The British use both this version and an older, palm - backward version ; the latter is obscene in American culture, and corresponds to the American "finger". Churchill got some surprised stares in 1941 when, evidently unaware of the mean usage, he gave the palm - backward "V" to British troops. In England today you could have to be a social hermit not to understand the distinction. Astonishingly, however, Margaret Thatcher repeated Churchill's error after her victory in the 1979 election.
1.What's the most popular meaning of the "V" sign?
A. Victory, B. Peace.
C. Cheat. D. Freedom.
2.Why did Churchill get some surprised stares according to the last paragraph?
A. He was proud of his troops.
B. He had wanted to be a hermit.
C. He wasn't insensible of the mean usage of the "V" sign.
D. He wanted to show congratulations to British troops.
3.What can be learned from the text?
A. The "V" sign simply means victory since 1941.
B. The "V" sign meaning peace was invented by a Belgian.
C. Thatcher made the same error as Churchill after her successful election.
D. American antiwar protestors used the sign to greet among freedom lovers.
4.What can we conclude from the passage?
A. It's never too old to learn.
B. Think well before you speak.
C. Actions speak louder than words.
D. Try to know culture diversity fully and regionally.
Would you go to war for your country? Millions of people do. But occasionally, some refuse to fight. They're known as conscientious objectors(拒服兵役者). One of the most famous from the USA is Muhammad Ali.
Muhammad Ali was a professional boxer and one of the most outstanding sports figures of the 20th century. He was born on 17th January 1942 in Louisville ( Kentucky) and began training as an amateur boxer when he was 12 years old. At the age of 18 , he won a gold medal in the light heavy-weight division at the 1960 Summer Olympics in Rome. He turned professional later that year. At the age of 22, he became the world heavyweight champion.
In 1965, he converted to Islam(伊斯兰教) and officially changed his name to Muhammad Ai. Shortly after, he was called up for military service to fight in the Vietnam War. He was firmly against the idea. "My enemy is the white people, not the Viet Cong(越共) ," he explained. "You may oppose when I want freedom. You may oppose when I want justice. You may oppose when I want equality…You want me to go somewhere and fight, but you won't even stand up for me here at home?"
After refusing to enlist during a sign - up ceremony in April 1967, Muhammad was arrested.
He was found guilty of draft evasion, and deprived of his boxing titles. As a result, he didn't fight from March 1967 to October 1970. He later became a symbol of the anti - war movement and racial injustice. In 1971, his conviction was overturned by the US Supreme Court. Muhammad Ali died on 3rd June 2016.
