Cryonics is the practice of cooling dead organic tissue. This is used on humans or animals that have recently died. The hope is to bring them back to life in the near future. By law, it can only be performed on humans after they are legally dead. Many scientists and doctors think cryonics is totally morally unacceptable. However, there are also many who support cryonics.
Supporters of cryonics hope that future technology will improve. Molecular technology is especially hoped to reverse (逆转) the early stages of clinical death. It is hoped that this will enable the repair of tissue on a very tiny level. It could also allow damaged tissues and organs to regenerate. They also assume that disease and aging will one day be reversible.
These supporters want to store the memory and identity from the brain of people who have recently died. Cryonics attempts to do this by using liquid that preserves the brain. If this is done before cooling, it will prevent injury. This cooling liquid saves the fine cell structures of the brain where memory and identity exist.
Critics of cryonics think this process is a waste of time and money. They base their opinions on the current level of science. It is true that cells, tissues, blood vessels, and some small animal organs can be reversibly preserved. Some frogs can even survive for a few months in a partially frozen state if they are kept a few degrees above freezing. But this is not true cryopreservation. There is no proof that the identity and memory of a person can be restored after death has occurred.
Critics also think that if it were possible to bring dead people back to life, it would cause many social problems. Critics worry it would cause a huge overpopulation problem. Many also think trying to reverse death is immoral because it is against the will of their God.

Say the phrase “female environmental pioneers,” and among the names you will hear are Rachel Carson, who wrote pesticides; chimpanzee expert Jane Goodall; and 17-year-old climate-change activist Greta Thunberg. To mark Women’s History Month, Kidspost is sharing the story of an environmental pioneer who is not that famous but equally remarkable.
At age 3, Sylvia Earle found her lifelong passion while playing on a beach. A wave suddenly came up and knocked her over.
“My mother ... saw the big smile on my face and let me run back in,” Earle told a TV interviewer years later. “And I’ve been running back in ever since.”
Earle is now 84 years old and has spent a lifetime exploring the world’s oceans and working to protect them from pollution, overfishing and other threats.
She is a pioneer in using scuba gear. Scuba gear lets divers take breath underwater. She holds the world record for the deepest untethered walk on the ocean floor at 1,250 feet. This means she was not tied to anything when she was walking underwater. During this exploration, she planted a U.S. flag.
In 1998, Time magazine gave Earle its first Heroes for the Planet award. She was the first female chief scientist at the National Oceanic and Atmospheric Administration (NOAA). It is the U.S. ocean and atmosphere group. She was also elected to the National Women’s Hall of Fame.
Earle has spent her life teaching people about the ocean. She notes how much it affects the weather, and what we eat and drink. She has something to say to those who don’t understand why the ocean matters. “They should know that with every breath they take, every drop of water they drink, the ocean is touching them,” Earle says. “You should treat the ocean as if your life depends on it— because it does.”

3.Which of the following words can best describe Earle?

4.Which of the following statement will Earle agree with according to the text?

Dear Leo,
Know that you are in low spirits for the quarrels with your parents，I would like to help you, but I can totally understand your feelings.
To start with it, you should know what this kind of communication problem worries nearly all the teenagers. Therefore, you don’t have to blame yourself not having a good relationship with your parents.
Actually, it isn't easy for them to talk about myself with my parents either, so my solve is to write down my thoughts in a letter to them. We need to tell them what we want and learn to negotiate. For example, I once get my parents to let me hang out with my friends on weekends unless I got better scores.
What’s more, trust the love of your parents for you and have some faith in them.
They will absolute listen to you and understand you in the end.
I’m looking forward to your good news.
Yours,
Li Hua
