Are you happy with your appearance? 1.
“Almost all the girls with single-fold eyelids in our class have had double-eyelid operations,” Zeng, a Senior 2 student from Chengdu, told Xinhua. Zeng had the same surgery done this summer. 2.
From popular photo-editing apps to plastic surgery, it seems that large eyes, pale skin and a skinny body are the only standard for beauty these days. But can following this standard really make us feel good about ourselves?
3. According to Huxiu News, over six in ten girls choose not to take part in certain daily activities, such as attending school, because they feel bad about their looks. As much as 31 percent of teenagers avoid speaking up in class because they worry that others will notice their looks.
Many teenagers are upset about their appearance because they believe in unrealistic standards of beauty, experts say. 4. Seeing all these things can make anyone believe that they’re too dark, too fat, too short, or too tall.
However, trying to live up to strict standards can make us feel anxious. What troubles us is not just our “imperfect” looks, but the fact that we criticize ourselves too much.
5. Plus-size models are being featured in some fashion shows. All of us should be just as confident as they are.

F. It’s not uncommon for teenagers to feel confident about their appearance．
G. Perfect faces and bodies are everywhere in advertising TV shows and social media．
People have been wondering why elephants do not develop cancer even though they have lifespans (寿命) that are similar to humans, jiving 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) developing. To be precise, they found 20 copies of an anti-tumor gene called TP53 in elephants. Most other species, including humans, only carry one copy.
According to the research, the extra copies of the gene improved the animal’s sensitivity to DNA damage, which 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,” the study author Dr Vincent Lynch told The Guardian. If every living cell has the same chance of becoming cancerous (癌变的), large creatures with a long lifespan like whales and elephants should have a greater risk of developing cancer than humans and mice. 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 (悖论)”. 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 as elephants. This means researchers could use the discovery to develop new treatments that can help stop cancers spreading or even developing in the first place.
“Nature has already figured out how to prevent cancer,” said Joshua Schiffman, a biologist at the School of Medicine, University of Utah, US. “It’s up to us to learn how different animals deal with the problem so that we can use those strategies to prevent cancer in people.”
1.Why are elephants unlikely to develop cancer?
A.They have a rather large body size.
B.Their genes suffer no DNA damage.

D.They carry many genes to prevent tumors developing.
2.According to the passage, what has been a risk in the evolution of large animals?
A.Deadly tumors. B.The huge body mass.
C.Cells killing themselves. D.Sensitivity to DNA damage.
3.What does the underlined part “This phenomenon” in Paragraph 5 probably refer to?
A.Larger animals have protection from TP53.
B.The risk of cancer is not related to body size.
C.Larger animals suffer the same risk of cancer as smaller ones.
D.The larger animals are, the bigger risk of cancer they will have.
4.What can be concluded from the passage?
A.Depending on nature is surely enough to fight against cancer.
B.The TP53 genes have proved useful in stopping cancer in people.
C.Humans are expected to prevent cancer with the making of TP53.
D.The extra copies of elephants, genes are used to cure cancer patients.

Aging brings wrinkles, sagging bodies and frustrating forgetfulness. But getting older is not all bad for many people. Mounting evidence suggests aging may be a key to happiness. There is conflicting research on the subject, however, and experts say it may all boil down to this: Attitude is everything.
Older adults tend to be more optimistic and have a more positive outlook on life than their younger and stressed opposites. The big question is why seniors are happier. A recent study suggests one reason: Older adults remember the past through happy memories. Aging can bring more cheer as people become more comfortable with themselves and their roles in society. The older adults said they were enjoying more time with their family, spending more time on hobbies and having greater financial security and did not have to work.
But others are doubtful about the link between happiness and growing older.
"The notion that those in old age are happiest is misleading," said Richard Easterlin, a professor of economics at the University of Southern California. "It is based on comparing people of different ages who are the same in terms of income, health, family life." Easterlin added, "When you take account of the fact that older people have lower income than younger, are less healthy, and more likely to be living alone, then you will find it hard to accept that they are happier.
In fact, scientists have found that as people age, their health declines and social networks disappear as their friends die, which can make the elderly less happy.
Even if one does give in to age's dark side, health and happiness don't always go hand-in-hand. It's all about attitude. Research by the University of Chicago’s Yang suggests that attitude about life and happiness, is partly shaped by the era in which a person was born. It turns out that individuals who adapt the best to changes also have the highest expected levels of happiness.
Despite the conflicting findings about aging and happiness, the good news is that there doesn’t appear to be a limit to how much happiness one can achieve in one’s life. “Most people desire happiness,” Easterlin said. “To my knowledge, no one has identified a limit to attainable happiness.”
1.What does the last paragraph mainly tell us?
A.The key factor to older adults’ happiness
B.There is a conflict between aging and happiness
C.No one can define the limit to happiness.
D.The relationship between health and happiness.
2.Why are some seniors happier according to some experts?
A.They focus on what makes them feel good.
B.They have their own circle of friends.
C.They have better income after retirement.
D.They can enjoy social welfare services.
3.What can we learn from the passage?
A.People of the same age have the same sense of happiness.
B.Attitude may play a very important role in happiness.
C.People who adapt the best to changes are more likely to be unhappy.
D.Older adults who have more valuable life experience are more optimistic.
4.What’s the topic discussed in the passage?
A.Whether aging or attitude brings happiness.
B.Why seniors adapt the best to changes in society.
C.What the limit to an elder person’s happiness is.
D.How older people feel compared with younger people.
