At the World Economic Forum last month, President Trump drew claps when he announced the United States would respond to the forum's proposal to plant one trillion(万亿) trees to fight climate change. The trillion-tree idea won wide attention last summer after a study published in the journal Science concluded that planting so many trees was “the most effective climate change solution to date”.
If only it were true. But it isn't. Planting trees would slow down the planet's warming, but the only thing that will save us and future generations from paying a huge price in dollars, lives and damage to nature is rapid and considerable reductions in carbon release from fossil fuels, to net zero by 2050.
Focusing on trees as the big solution to climate change is a dangerous diversion(偏离). Worse still, it takes attention away from those responsible for the carbon release that are pushing us toward disaster. For example, in the Netherlands, you can pay Shell an additional 1 euro cent for each liter of regular gasoline you put in your tank, to plant trees to balance the carbon release from your driving. That's clearly no more than disaster slightly delayed. The only way to stop this planet from overheating is through political, economic, technological and social solutions that end the use of fossil fuels.
There is no way that planting trees, even across a global area the size of the United States, can absorb the huge amounts of fossil carbon released from industrial societies. Trees do take up carbon from the atmosphere as they grow. But this uptake merely replaces carbon lost when forests were cleared in the first place, usually long ago. Regrowing forests where they once grew can undo some damage done in the past, but even a trillion trees can't store enough carbon to head off dramatic climate changes this century.
In a sharp counter argument to last summer's Paper in Science, Justin Gillis wrote in the same journal in October that the study's findings were inconsistent with the dynamics of the global carbon cycle. He warned that “the claim that global tree restoration(复原) is our most effective climate solution is simply scientifically incorrect and dangerously misleading”.

How did you develop from an infant(婴儿),with a few elementary thinking skills, to the adult you are now, with the ability to reason and analyze the world in many complex ways involving language, symbols and logic? Your first reaction to this question may be very likely to say, “Well, I learned how to think from my experiences and from the teaching I received from adults through my life.”
Although this explanation seems naturally correct to most people, many developmental psychologists believe that much more is involved in acquiring intellectual abilities than simple learning. The current view about intellectual development is that it is a process of maturation, much like physical development, that occurs in a predictable fashion from birth through adulthood.
Do you look at an infant and see a person who, with enough learning, is capable(有能力的) of adult physical behaviors? Of course not. Instead, you know that the child's behavior will become increasingly complex over time through a process of physical maturation. You know that until the child achieves a certain level of development, all the learning in the world cannot produce certain behaviors. For example, consider the behavior of walking. You probably think of walking as a learned behavior. But imagine trying to teach a 6-month-old to walk. You could place the infant on an Olympic-level schedule of 8 hours practice every day, but the child will not learn to walk, Wily? Because the child has not yet reached the physical maturity to perform the behaviors needed to walk.
Intellectual development occurs in much the same way. Children simply cannot display certain thinking and reasoning abilities until they reach an appropriate stage of intellectual development, no matter how much learning they may have experienced.
1.What is most people's view on intellectual development?
A.It depends on experience and education.
B.Its process is simple and predictable.
C.It is similar to physical development.
D.It just happens naturally in life.
2.What can we learn about physical development from the text?
A.It stops naturally, at an early age.
B.It happens through simple learning.
C.It is part of intellectual development.
D.It occurs in the process of growing up.
3.Why is walking mentioned in paragraph 3?
A.To show behaviors can't be learned till a certain age.
B.To prove walking can be learned at any stage in our life.
C.To indicate a baby can't learn to walk without parents, help.
D.To suggest more practice can produce more learned behaviors.
4.Where is this text most likely from?
A.A research paper.
B.A science magazine.
C.A teaching guidebook.
D.A children's newspaper.
Several years ago, a public school teacher was hired to visit children who were patients in a city hospital. Her job was to tutor them with their schoolwork.
One day, this teacher received a routine call requesting that she visit a particular child. She was told by the teacher on the other end of the line. “We’re studying nouns and adverbs in Class now. I’d be grateful if you could help him with his homework.”
It wasn’t until the visiting teacher got outside the boy’s room that she realized it was located in the hospital’s burn unit. No one had prepared her for that. When she walked into the room, she found the young boy, horribly burned, was obviously in great pain. The teacher felt awkward and didn’t know what to say, but she had gone too far to walk out. Finally, she was able to stammer out, “I…I’m… the special visiting hospital teacher, and your teacher sent me to help you with your nouns and adverbs.” Afterward, she thought it was not one of her more successful tutoring sessions.
The next morning when she returned, a nurse stopped her, “What did you do to that boy?” Before she could finish her apologies, the nurse interrupted her by saying, “You don’t understand. We’ve been worried about him, but ever since you were here yesterday his whole attitude has changed. He’s responding to treatment…”
In fact, the boy had completely given up hope and felt he was going to die until he saw that special teacher. Everything had changed with an insight gained by a simple realization. With happy tears in his eyes, the little boy said, “They wouldn’t send a special teacher to work on nouns and adverbs with a dying boy, now, would they?”
1.Why did the teacher feel awkward after entering the room?
A.She walked into the wrong room.
B.She was too eager to be successful.
C.She had no idea how the boy was suffering.
D.She was not well prepared for her lesson.
2.What does the underlined word “stammer” in paragraph 3 mean?
A.To speak with a fear.
B.To speak with a pause.
C.To speak with a concern.
D.To speak with a gesture.
3.What can we infer from the teacher’s action of apologizing?
A.She got scared by the hospital nurse.
B.She was a person of modest personality.
C.She thought she made the boy uncomfortable.
D.She realized she got the usage of a noun wrong.
4.What helped the boy regain hope?
A.He felt the learning pressure from the special teacher.
B.He believed that the teacher was expert at teaching grammar.
C.He was aware that everyone was trying their best to care for him.
D.He realized that he was not in so bad a situation as he had assumed.

The “novel” coronavirus, being called COVID-19 officially, had not previously been detected before the outbreak is reported in Wuhan, China in December, 2019. Infection with 2019-nCoV can cause mild symptom including a runny nose, sore throat, cough, and fever. It can be most severe for some persons and cause pneumonia or breathing difficulties. More rare, the disease can be deadly. It can be transmitted from person to person, usually after close contact with infected patient that even seems healthy.
To protect yourself, wash your hands frequently with soap and water. Maintain at least 1 meter distant between yourself and other people, particularly those who are coughing and sneezing. Wear a medical mask can help limit the spread of some respiratory (呼吸的) diseases. Therefore. it has to be combined to other prevention measures including washing hands and avoiding close contact to take effect.
