21、Zhang Fan, 36, a movie visual effects designer who returned to Beijing from New Zealand for work last year, was surprised by the improvement to the city’s air quality. “I remember the smell in the air and the frequent smoggy days before I left in 2013, after getting a job offer from a film company in New Zealand, ” he said. Last year, a Chinese company offered Zhang a more promising position, so he returned, saying that he could find more opportunities in his line of work in Beijing than elsewhere. In addition to rapid economic development in the Chinese capital, he said the most impressive change is the local air quality. “People discussed air pollution a lot when I was in Beijing previously. Now, it seems that the topic has disappeared completely, as every day is good in terms of air quality,” Zhang said. “The sky in Beijing these days is so clear. ”
On Jan. 4, the municipal authorities in Beijing announced a comprehensive success in improving air quality, with the city’s annual average concentration of PM2. 5 in the air, falling to 33 micrograms per cubic meter, and ozone (臭氧) concentration dropping to 149 mcg per cu m last year.
Yu Jianhua, spokesman for the Beijing Municipal Ecology and Environment Bureau, said at a news conference, “This is a milestone for Beijing’s hard work in fighting air pollution and also means that the city has met its air quality target outlined in the 14th Five-Year Plan(2021-25) ahead of schedule. Beijing has demonstrated to the world over the past 20 years that a mega city with a rapidly increasing GDP, vehicle count, population and energy consumption can move forward to cut air pollution effectively. The PM2.5 reduction over the past few years has surpassed that of developed countries during the same period.
According to the Bureau, the city’s average concentration of PM2.5 dropped by 63 percent last year from 2013, an average annual reduction of about 8 percent. The city experienced 288 days of good air quality last year—up from 112 days in 2013—and just eight days of heavy air pollution. This achievement is clear to see and exciting, but it has not been easy work.
【1】Why did Zhang Fan retumed to Beijing?
A．He was tired of his life abroad.
B．He has a deep affection for the city.
C．The city’s air quality has improved.
D．A golden chance was offered to him.
【2】How do the municipal authorities show the improvement to the city’s air quality?
A．By using examples.
B．By using figures.
C．By offering experimental findings.
D．By citing personal experience.
【3】What does the underlined word “mega” in Paragraph 3 probably mean?
A．Huge.
B．Rich.
C．Civilized.
D．Noted.
【4】In which section of a newspaper may this text appear?
A．Business.

22、To make sure of greener development, China will combine efforts in environmental protection and ecological restoration according to the country’s newly approved guideline for environmental protection, part of the 13th FiveYear Plan (2016—2020).
China surpassed its goal in environmental protection for the 12th FiveYear Plan (2011—2015), with carbon intensity dropping by 20 percent (the intended target is 17 percent). It is a major contribution to worldwide efforts against climate change, officials said.
The new guideline stresses efforts to restore nature while reducing industrial damage to the environment. The goal is to achieve a more environmentally friendly way of living, considerable reduction in major pollutant emissions and a sounder ecological system by 2020. A good environment is a necessary part in improving people’s living standards, officials said.
Statistics of a report from several Chinese universities show that more than one third of the country’s industrial waste water flows directly into rivers and lakes. Water pollution within China has affected the environment, society and agriculture. It has resulted in huge economic losses. Air pollution is also one of the major problems in China. Heavy haze usually covers North and East China. Environmental issues are becoming a barrier to China’s development. Besides, heavy metal pollution in soil in China is so serious that it requires us to act immediately. 10 percent of the total farmland of China has heavymetalpolluted soil. The heavy metal in soil will enter into humans’ food chain through grain and agricultural products.
The rapid industrialization of agriculture, expansion of the chemical industry, and the need to produce cheap forms of energy have caused the continuous release of manmade organic chemicals into natural ecosystems. The guideline focuses on ecological restoration by controlling more types of pollutants than before.
【1】According to the passage, the guideline ________.
A．is part of the 12th FiveYear Plan of China
B．aims to improve Chinese people’s living standards
C．calls for worldwide efforts against climate change and pollution
D．focuses on environmental protection as well as ecological restoration
【2】The underlined word “surpassed” can be replaced by “________”.
A．beat
B．failed
C．set
D．realized
【3】What does Paragraph 4 mainly talk about?
A．The huge influence of serious pollution on China.
B．The current situation of environmental pollution in China.
C．China’s achievement in fighting pollution in recent years.
D．Measures the Chinese government takes to deal with pollution.
【4】What can we know from the passage?
A．Most cities in China suffer serious air pollution.
B．Water pollution is the biggest problem compared with other kinds of pollution.
C．More types of pollutants should be controlled to restore ecosystems.
D．Reducing carbon emissions is the chief goal of the 13th FiveYear Plan.
23、One step too far
Scientists have been trying to figure out how to alter the genes of humans for many years now, and it looks like they've finally cracked (破解) the code. But while this may seem like a great step forward in science, some also believe that it's one step back when it comes to ethics.
In August, a group of scientists from the US and South Korea worked together to successfully edit a human embryo and remove a genetic mutation (突变) that would have led to heart disease, reported The Guardian.
This was achieved with the help of CRISPR, a gene-editing tool that allows scientists to “cut and paste” human DNA.
Although this was the first example of an embryo's genes being changed successfully, the benefits of gene editing have already been tested in living patients.
In 2015, a five-month-old girl from the UK was saved after doctors used edited cells to fight off her cancer. As of today, she's alive and well.
And in the US last year, scientists managed to remove HIV cells from several patients by editing the genes inside their bodies.
Some people hope that in the future, diseases or birth detects could simply be “edited out”. However, others believe this could lead to so-called designer babies, giving parents the option to choose everything from eye color to intelligence.
“You could find wealthy parents buying the latest ‘upgrades’ for their children, leading to even greater inequality than we already live with,” Marcy Darnovsky, director of the San Francisco Center for Genetics, told BBC News.
In spite of these ethical concerns, experts say it’s not possible to create the “perfect” human being. Despite the progress scientists have made, we don’t understand human genes enough to give all unborn child great brainpower or amazing singing abilities.
“Right now, we know nothing about genetic enhancement,” Hank Greely, a director of sciences at Stanford University, US, told The New York Times. “We’re never going to be able to say, honestly, ‘This embryo looks like it would score high on the two-part SAT.’”
So it looks like if we want good exam results, or to impress people with our piano skills, we’ll have to stick with the old fashioned method of plain hard work — at least for now.
【1】The underlined word “alter” in Paragraph 1 probably means ______.
A．record
B．change
C．remove
D．increase
【2】Why do some people consider human gene editing a step backwards？ ______
A．They don't think it is an effective way to light diseases.
B．They are concerned that it could lead to genetic mutations.
C．They think it could lead to designer babies and increased inequality.
D．They worry that it could make parents abandon children with birth defects.
【3】What was the first successful example of human embryo gene editing？ ______
A．A genetic mutation related to heart disease was removed by scientists
B．A newborn baby with cancer was saved by edited cells.
C．HIV cells were removed from patients’ bodies.
D．Some birth defects were simply edited out.
【4】What can we conclude from the text？ ______
A．Gene editing is regarded as the perfect way to treat birth defects.
B．There is still a long way to go to fully understand human genes.
C．Gene editing could help enhance human intelligence in the near future.
D．Scientists are pessimistic about the future of gene editing.
24、How to Be Creative
Most of us think that creativity is a quality (品质) belonging only to artists, writers, or dancers, rather than ourselves. 【1】 The following tips are a great beginning for developing our creativity.
Get out of your comfort zone
We eagerly accept the familiar and fear the unknown. Break out of your usual patterns and welcome creativity into your life. As said earlier, the human brain was designed to recognize patterns. 【2】 In fact, our comfort zone is nothing more than a collection of patterns. As we become more efficient at recognizing and using patterns, we rely less on creativity to find new paths. We should force ourselves out of our comfort zones and open up new possibilities.
Try different things
If you always do what you’ve always done, you’ll always get what you’ve always got. We are creatures of habits and routines, and creativity hates routines (常规). If you usually drive to work, take the subway for a few days. 【3】 Break your routine, experiment and try something new. New things are often creative, but the same old thing never is.
【4】
Having a great idea is not enough, you must work to make it a reality. Have you ever seen a new product and realized that you thought of the same thing long ago? Yet someone else is making money with “your” idea. 【5】 The difference between a dreamer and a doer is action. Do whatever it takes to bring your ideas to life. If you can put them into practice, you are well on your way to improving your creativity in all areas of your life.
A．Take action
B．Seek several options
C．Think from the other person’s point of view.
D．If you normally eat in the office, have lunch under a tree.
E．We continue to create patterns for almost everything we do.
F．The truth is that we are all born with the ability to be creative.
G．We all have great ideas sometimes, but only a few people turn their ideas into realities.
