One Saturday morning, I was watching TV with my parents when a piece of news caught our attentions. The Guangming Park called on people adopt trees. That's exact what we had been thinking about. So on the next morning, we went to the park directly. A worker there gave us a detailed introduction or showed us to the pine woods. We choose a beautiful pine tree and the worker tied a adoption card to it. When my name was seeing on the card, I was so proud and felt a sense of responsibility at the same time. To memorize the excited moment, we took photos with our new family member—the pine tree. In one of the photos, we both smiled from the bottom of our hearts.

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.

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.
C. Making humans temporarily lose memory. D. Making humans suffer heart attack.
4.What's the best title of this passage?
A. High Poisonous Acid Appears in the Animals
B. The West Coast Crab Industry Suffer Great Loss
C. Climate Change Warms the Oceans in the World
D. Warmer Oceans Increase Likelihood of Poisonous Shellfish
