21、 Zhong Zhong and Hua Hua have made medical history as the first cloned primates (灵长目动物),with the efforts of a team of Chinese scientists.
According to the journal Cell , it is a milestone for biomedical research. It could potentially lead to the development of new treatments for human disease. But it also makes ethicists (伦理学者) about where this all might lead. Do Zhong Zhong and Hua Hua suggest the coming of human cloning?
Born in 1996, Dolly the sheep was the first cloned mammal, and was followed by many more, including dogs, rabbits and pigs. But researchers were unable to clone primates because the genes involved didn’t react well to the procedure. Over the years, a handful of research institutions have tried and failed to birth a live monkey clone.
The successful team, at Shanghai’s Chinese Academy of Sciences, used the same basic method that created Dolly but had failed in subsequent(随后的) primate cloning attempts. It’s called somatic（躯体）cell nuclear transfer and involves transferring DNA from adult cells into eggs that have had their own DNA removed. Without the addition of sperm(精子), the eggs are stimulated （刺激）chemically to develop into an embryo that’s a clone of the DNA donor(提供者). The embryo is then placed into a substitue(替代) for gestation（妊娠）.
The researchers modified the approach in two important ways, however. Rather than use adult cells in the DNA transfer, they used fetal (胎儿)cells, which react better to chemical stimuli（刺激）for embryo development, says Mu-ming Poo, director of the academy’s Institute of Neuroscience and a co-autho of the paper. They also fine-tuned the cell transfer process to minimize damage to the eggs
As for creating human clones, Poo says the research shows it can be done, but he and his team have no interest. “Besides many technical dificulties that remain to be overcome, we see no justifiable reason to do human cloning,” says Poo, “nor would the societies around the world permit such an attempt.”
While human cells may be cloned experimentally, for example to research tissue regeneration, the cloning of an entire human is illegal in more than 70 countries, according to the Center for Genetics and Society. U.S. law does not ban it, but over a dozen states do. (Discover 2019J&F,P60.)

22、Life is full of peaks and valleys. Sometimes you’re up, and sometimes you’re down.【1】 when you can improve your ability to deal with the difficult times. Here’s how to make getting through hard times less difficult.
Stay positive. When you stay positive, you’re putting yourself in the best position possible to not only make it through those bad times, but become a better person in the process.【2】when life takes a turn for the worst. You can remain positive and remind yourself that there really is a light at the end of the tunnel（隧道）and that you’ll make it through, or you can relegate（降级）yourself to being nothing more than a victim of circumstance.
【3】. You’re setting yourself up for frustration（沮丧）when you focus your time and energy on things you can’t control. You should instead focus on the things that are within your control because that’s the only way you can make a change that’s actually going to help you. Make a list of everything you can control about the situation and put all of your focus on them. 【4】.
Realize you have come a long way. Sometimes we get so focused on the road ahead that we never look back to see what we’ve already traveled.【5】. You will increase your own confidence when you realize that you have already made so much progress and the light at the end of the tunnel will get brighter.
Practice what is mentioned above, and you will find that the difficult times you’re going through will start to seem less significant.
A．You can do one of the two things
B．Learn from the difficult times and control them
C．Focus on what you can control, not what you can’t
D．Anything that’s not on the list doesn’t get any attention
E．Give yourself praise for everything you have already done
F．You not only live a happier life, but you also grow as a person
G．The difficult times on the list mean you need a little more guidance
23、We often hear that 60 is the new 50. Just check out the images of your grandparents or greatgrandparents and notice their stooped (曲背的) bodies, their wrinkled faces when they were barely pushing 60. What a contrast with energetic, gymgoing sexagenarians (六十几岁的人) of today !
The research overseen by gerontologist(老年学专家)Taina Rantanen, compared adults born in 1910 and 1914 with those born roughly 30 years later. Both birth groups were examined in person at age 60 and again at 70 with the same set of six physical tests and five measures of cognition(认知).
According to the research, the laterborn group could walk faster, had a stronger hand grasp and could use more force with their lower legs. On cognitive tests, the laterborn group had better verbal fluency, and scored higher on a test matching numbers to symbols. But not everything changed across the generations: measures of lung function were surprisingly not changing, and there was no improvement in the shortterm memory task of recalling a series of figures.
There are many reasons why people are aging better, including improved medical care and a drop in smoking, but the key factor shown in the study of physical function was that the laterborn adults were more physically active and had bigger bodies, which suggested better nutrition. For brain function, the key seemed to be more years of education.
“Education is a powerful influence on aging and health,”says Luigi Ferrucci, scientific director of the U. S. National Institute on Aging. “With more education, you are probably going to have a larger income, which means you are more likely to go to the doctor, and have good nutrition.” He also points out that the average lifespan is seven years shorter in a poor state such as Mississippi than in a wealthier one such as California. “Here we still have lots of people who cannot take the drugs they need because they cannot pay for them,” he says. In short, 60 may be the new 50 for many of us but not for all.
【1】How does the writer begin the passage?
A．By imagining a scene.
B．By presenting an image.
C．By raising a question.
D．By making a comparison.
【2】Which of the following is true about the research?
A．The laterborn group could hardly grasp things tightly.
B．Everything didn’t change across the generations.
C．The laterborn group did worse in matching numbers to symbols.
D．There was a little improvement in shortterm memory in both groups.
【3】According to the research, what contributes most to better physical aging?
A．Better nutrition.
B．Education.
C．Improved medical care.
D．Energetic images.
【4】What is the main idea of the passage?
A．Many reasons contribute to people’s better physical function.
B．Today’s energetic sexagenarians have much better images.
C．Education is the key to people’s better aging.
D．People today are aging better than people born earlier.
24、Friendships mean a lot in our life. 【1】 Be sure that the people who are close to you are the ones that make your life better, not worse. Remember, good friends improve your life, while toxic friends harm it.
The User
This type of friend is sometimes called a fair-weather friend. The User seems to be there for you, and make plans with you—that is, until something better comes along. This friend is always looking for a way to improve their social position. They also do not want to be alone on the weekend. 【2】 You deserve (值得) a friend who is your friend through thick and thin.
The Leech
【3】 They expect you to drop everything when they call. While it is important to be a supportive friend, with this type of friend, you have to set boundaries (界限). If you do not, after a while, this type of friend will take up most of your time.
The Negative Nellie
This friend is never happy with anything they have. 【4】 Negative Nellies are also likely to have negative opinions about almost everything. Not only is this type of friend negative about their life, but they also direct that negativity toward you. They may judge everything from the clothes you wear to the people you talk to. They also struggle with envy at times and will never praise you. Look for friends that can be happy for you and supportive.
The Drama Queen
This friend’s life is like one long soap opera (肥皂剧). Every day there seem to be letdowns and sadness. With this friend, you become the problem-solver. But remember, they are probably not really interested in changing. 【5】 Drama Queens pay all attention to their life, and they never notice what you need.
A．This friend may put you in danger.
B．This type of friend always needs you.
C．They spend a lot of time complaining.
D．It is important to choose your friends wisely.
