27、Antarctica is known for being a vast land of ice and snow, a place too cold for most life. Despite this, the continent is slowly starting to turn warm. According to the Guardian, the Antarctic has registered (登记) a new high temperature for the first time on record, prompting fears of climate instability in the world’s iciest place.
On Feb 9, Brazilian researchers at Seymour Island reported a temperature of 20. 75 C on the icy continent of Antarctica. It was almost a full degree higher than the previous record of 19. 8 C, taken on Signy Island in January 1982.
This record-breaking reading was taken at a monitoring station in the northern part of Antarctica. According to Brazilian soil scientist Carlos Schaefer, the temperature was documented during a 20-year-long research project. The focus of this project is to study the effect that climate change has on the permafrost (永久冻土) within the region. Permafrost is soil that stays frozen for at least two years. Although this is a record high for Antarctica, Schaefer stressed that “We can’t use this to anticipate climatic changes in the future. It’s simply a signal that something different is happening in that area. ”
But in fact, the last high temperature reading was in the 19 C range. These higher temperatures can cause ice and glaciers (冰川) in Antarctic regions to melt. The Antarctic peninsula (半岛)—the long finger of land that stretches toward Argentina—is most dramatically affected. Scientists saw glaciers that have retreated by more than 100 meters in Discovery Bay where the snow melted in little more than a week, leaving dark exposed rock. This melted ice leads to a rise in sea levels that can threaten the safety of coastal areas. It’s believed to be behind an alarming decline of more than 50 percent in chinstrap penguin (帽带企鹅) colonies, which are dependent on sea ice.
Like American writer Ernest Hemingway once said, “The Earth is a fine place and worth fighting for. ” We should do everything we can to help save our planet. Otherwise, it may become too hot for us to fix.

28、When a child is told he is "uncool", it can be very painful. He may say he doesn't care, and even act in ways that are opposite of cool on purpose. But ultimately, these are simply ways to handle sadness by pretending it's not there.
Helping a child feel better in school had to be careful. If you say, "Why are you worried about what other children think about you? It doesn't matter!" children know that it does matter. Instead, an active way may be best. You could say, "I'm going to do a couple of things for you to help you feel better in school."
If a boy is having trouble making friends, the teacher can help him. The teacher can arrange things so that he has chances to use his abilities to contribute to class projects. This is how the other children learn how to value his good qualities and to like him. A teacher can also raise a child's popularity in the group by showing that he values that child. It even helps to put him in a seat next to a very popular child, or let him be a partner with that child in activities, etc.
There are things that parents can do at home, too. Be friendly when your child brings others home to play. Encourage him to invite friends to meals and then serve the dishes they consider "super". When you plan trips, picnics, movies, and other shows, invite another child with whom your child wants to be friends.
What you can do is to give him a chance to join a group that may be shutting him out. Then, if he has good qualities, he can start to build real friendship of his own.
【1】A child who has been informed of being "uncool" may _____.
A. care nothing about it
B. develop a sense of anger
C. do something uncool purposely
D. pretend to get hurt very much
【2】A teacher can help an unpopular child by _____.
A. seeing the child as the teacher's favourite
B. asking the child to do something for partners
C. forcing other children to make friends with the child
D. offering the child chances to show his good qualities
【3】How can parents help their child fit in better?
A. By cooking delicious food for him.
B. By being kind to his schoolmates.
C. By forcing him to invite friends home.
D. By taking him to have picnics in the park.
【4】Which of the following is TRUE?
A. Children don't care about others' comments on them.
B. It's only a teacher's work to make children popular.
C. Parents should take their children out for picnic and shows more often.
D. Inviting children's friends to family activities is good for them to make friends.
29、 Elephants have impressed us for centuries. They are big, clever, and sociable. But what if someone told you that they may also hold the key to fighting cancer (癌症)?
People have been wondering why elephants do not develop cancer, even though they have lifespans (寿命) that are similar to humans, living for around 50 to 70 years.
Now scientists believe they know why. A team at the University of Chicago, US has found that elephants carry a large number of genes that stop tumors (肿瘤) from developing. To be precise, they found 20 copies of an antitumor gene called TP53 in elephants. Most other species, including humans, only carry one copy.
According to the research, which was recently published on the online science network BioRxiv, the extra copies of the gene improved the animal's sensitivity to DNA damage. This lets the cells quickly kill themselves when damaged before they can go on to form deadly tumors.
“An increased risk of developing cancer has stood in the way of the evolution of large body sizes in many animals，” study author Dr. Vincent Lynch told The Guardian. If every living cell (细胞) has the same chance of becoming cancerous, large creatures with long lifespans like whales and elephants should have a greater risk of developing cancer than humans and mice do. But across species, the risk of cancer does not show a connection with body mass.
This_phenomenon was found by Oxford University scientist Richard Peto in the 1970s and later named “Peto's paradox”. Evolutionary (进化的) biologists believe it results from larger animals using protection that many smaller animals do not. In the elephant's case, the making of TP53 is nature's way of keeping this species alive.
The study also found that when the same genes were brought to life in mice, they had the same cancer resistance (抵抗) as elephants. This means researchers could use the discovery to develop new treatments that can help stop cancers from spreading or even developing in the first place.
“Nature has already figured out how to prevent cancer, ” said Joshua Schiffman, an oncologist at the School of Medicine, University of Utah, US.
“It's up to us to learn how different animals tackle (处理) the problem so we can use those strategies to prevent cancer in people.”
【1】Why are elephants unlikely to develop cancer?
A. They have a large body size.
B. Their genes suffer no DNA damage.
C. Certain genes in their body kill existing tumors.
D. They carry many genes that keep tumors from developing.
【2】According to Dr. Vincent Lynch, what has been a risk in the evolution of large animals?
A. A risk of deadly tumors. B. Human behavior.
C. Extreme weather. D. Cells killing themselves.
【3】What does the underlined expression “This phenomenon” in the sixth paragraph refer to?
A. Larger animals have protection from TP53.
B. The risk of cancer is not related to body size.
C. The larger animals are, the bigger risk of cancer they have.
D. Larger animals suffer the same risk of cancer as smaller ones do.
【4】We can conclude from the last three paragraphs that ________.
A. humans are expected to stop cancer in the near future
B. depending on nature is not enough to fight against cancer
C. this new treatment is more effective than the present ones
D. the TP53 genes have proven useful in stopping cancer in mice
