21、I was driving from Harrisburg to Lewisburg last night, a distance of about eighty miles. It was late. Several times I got stuck behind a slow-moving truck on a narrow road with a solid white line on my left, and I was clinching (紧握) my fists with impatience.
At one point along an open highway, I came to a crossroads with the traffic light. I was alone on the road by now, but as I approached the light, it turned red and I braked to stop. I looked left, right and behind me. Nothing. Not a car, no suggestion of headlights, but there I sat, waiting for' the light to change, the only human being for at least a mile in any direction.
I started wondering why I refused to run the light. I was not afraid of being arrested, because there were obviously no police around, and there certainly would have been no danger in going through it.
Much later that night, the question of why I'd stopped for that light came back to me. I think I stopped because it's part of an agreement we all have with each other. It's not only the law, but it's an agreement we have, and we trust each other to honor it: we don't go through red lights.
It's amazing that we ever trust each other to do the right thing, isn't it? And we do, too. Trust is our first tendency. We have to make a deliberate decision to mistrust someone or to be suspicious or skeptical. Those attitudes don't come naturally to us.
It's a very good thing too, because the whole structure of our society depends on mutual trust, not distrust. This whole thing around us would fall apart if we didn't trust each other most of the time. We do what we say we'll do; we show up when we say we'll show up; we deliver when we say we'll deliver; and we pay when we say we'll pay. We trust each other in these matters, and when we don't do what we've promised, it's far from the normal. It happens often that we don't act in good faith and in a trustworthy manner, but we still consider it unusual, and we're angry or disappointed with those badly-behaved people. Anyway I was so proud of myself for stopping for the red light that night.

22、 The moon may shine white above us most nights of the year, but how much do we know about Earth’s neighbor and what lies beneath its surface? Scientists are aiming to find out.
On Jan 3, 2019, China’s Chang’e 4 spacecraft landed on the far side of the moon – a first for humanity. It released a small probe (探测器), Yutu 2, or Jade Rabbit 2, which began to search beneath the moon’s surface using Lunar Penetrating Radar. These radio signals can reach 40 meters underground, three times the depth of the Chang’e 3 lunar probe launched in 2013 for the near side of the moon, China Daily reported.
In a study published in the journal Science Advances, researchers found that the lunar soil’s top layer on the far side of the moon was much thicker than expected – about 40 meters. Other scientists only expected about 6 millimeters of soil based on NASA observations during the Apollo moon landings, according to The New York Times.
“It’s a fine, dusty, sandy environment,” said one of the authors of the study, Elena Pettinelli, a physics and mathematics professor at Rome Tre University, Rome.
Yutu 2 is specifically exploring the Von Karman crater (大坑), a large hole that’s 180 kilometers wide and also the landing site of Chang’e 4. It’s part of an even larger, older crater spanning more than 1,770 kilometers.
“The subsurface at the Chang’e 4 landing site is very complex,” said Li Chunlai, a research professor and deputy director-general of National Astronomical Observatories of the Chinese Academy of Sciences. Observations suggest that the subsurface material is totally different than the previous landing site of Chang’e 3, she said.
Radar waves revealed various layers beneath the moon’s surface: grainy (颗粒状的) material, boulders (岩石), and further layers of fine and coarse (粗糙的) particles. This information is helping scientists to gain new understanding of the moon’s history and formation, as well as volcanic activity and lunar impacts.
Yutu 2 is the longest-working rover (巡视器) on the moon, but it won’t last forever. China plans to launch the Chang’e 5 probe later this year, Xinhua News Agency reported. The spacecraft is expected to bring pieces of the moon back to Earth for closer study.
【1】What can we learn about the Chang’e 4 probe?
A.It was the first to land on the moon’s near side.
B.It explored areas as wide as 1,770 kilometers.
C.It is three times as large as the Chang’e 3 lunar probe.
D.Its signals could reach 40 meters beneath the moon’s surface.
【2】What does the lunar soil’s top layer on the moon’s far side look like, according to the text?
A.It looks like a large hole.
B.It is about 6 millimeters thick.
C.It goes farther down than expected.
D.It is covered by boulders and fine and coarse particles.
【3】What is the Chang’e 5 probe expected to do?
A.Bring lunar samples back to the Earth B.Explore the Von Karman crater.
C.Replace Yutu 2 to explore the moon. D.Identify the moon’s various layers.
【4】What is the text mainly about?
A.A history of Chinese lunar missions.
B.A report on the Chang’e 4 probe’s findings.
C.A comparison of the Chang’e 3 and 4 probes.
D.How Yutu 2 explored beneath the moon’s surface.
23、When plumbing (水暖设备) makes funny noises, it’s not always a good sign. But John Kovac, a harpist (竖琴演奏者) from Virginia, likes the pipes to sing. He thinks plumbing pipes make good musical instruments.
Kovac has made standard harps out of wood for more than 20 years. He says he feels excited when he creates an instrument with his hands and uses it to make music come alive. But it takes years of training and special tools to make a traditional musical instrument. Kovac wanted to share the joy of making instruments with people who might not have the time or money to do it. So he decided to find an easier way.
Plumbing was the answer. Kovac found PVC pipes at a local store. PVC pipes are the white tubing that many plumbers use. You might find some in your house under a sink or in the basement. Kovac says that PVC pipes are great for making instruments because they are inexpensive, come in many shapes and sizes, and fit together perfectly.
Kovac makes harps, guitars, violins, and drums out of PVC pipes. He also makes uncommon instruments like the udu from Nigeria. His instruments may look as if they come from outer space, but they really work. He and some of his music students and friends even started a band called the East Coast PVC Band.
Sally Seabright is a violin teacher who plays the PVC violin with the band. At first, the rounded shape of the PVC violin made it difficult to hold between her chin and shoulder, but Kovac made a slight change by adding a piece that fits perfectly under her chin. That kind of adaptability is what Kovac admires about PVC. He says, “I know it’s not easy for the average person to make a musical instrument, but I hope to enable anyone who has ever dreamed of making a violin, harp, or guitar to fulfill his or her dreams.”
【1】What does the author intend to show in paragraph 2?
A．The great hardships of being a harpist.
B．The different instruments Kovac has created.
C．The process of making a musical instrument.
D．The reason Kovac came up with his creative idea.
【2】Why have PVC pipes won Kovac’s favor?
A．They are environmentally friendly.
B．They are highly available and adaptable.
C．They can make better sounds than wood.
D．They offer a selling point for his instruments.
【3】What can be learned about the PVC instruments from paragraph 4?
A．They are a bit difficult to hold for players.
B．They are very unusual in the way they look.
C．They are inspired by outer space elements.
D．They are designed to play traditional music.
【4】Why does the author mention Sally Seabright in the last paragraph?
A．To explain Kovac’s dream.
B．To show the strength of PVC.
C．To describe his passion for music.
D．To introduce the East Coast PVC Band.
24、 Born on July 1st, 1948, in the small Italian city of Palmi, Roberto Crea was a genius kid. He moved to the Netherlands and majored in Biological Chemistry in the University of Leiden. It was this university that directed his interest in the synthesis (合成) of nucleotides, the basic units that are required to build a DNA. At that time, not many researchers studied the combination of genes (基因)，but Roberto’s strong chemistry background made a historical invention possible.
In 1977, he joined the Genentech, Inc. and the gene synthesis team at City of Hope Medical School. The company funded Dr. Crea’s on-going research on gene synthesis. After working day and night, the brilliant individual finally invented a new procedure that improved the chemical synthesis of genes. Thanks to his rich knowledge and the joint efforts of the excellent Genentech team, he made use of this discovery to produce the human Insulin (胰岛素) genes, A and B. It was his invention that allowed Genentech to be labeled as the first producer of human protein. This benefited
hundreds of millions of people suffering from diabetes (糖尿病) all over the world.
Today Roberto is known as the father of synthetic insulin and had almost won the Nobel Prize. His efforts did not stop after discovering the synthetic insulin; in fact, he was more than driven and tried to make more contributions to the field of biotechnology. His team of experts discovered Ziconotide under his teachings and guidance. According to leading scientists and researchers, this drug is more powerful and effective than morphine (吗啡),and the best part of this is that it has zero side-effects.
Dr. Roberto Crea has a long list of creditable discoveries and researches that he has achieved in 65 years of his life. He is an inspiration for many individuals who aim to add value to humanity with the help of science..

25、Optimism and pessimism are both powerful forces. Each of us must choose which we want to ______ our future and our expectations. We can choose to laugh or cry, bless or ______. It’s our decision: from which perspective do we want to view life? Will we look up in ______or down in desperation?
I believe in the upward look. I choose to ______the positive and skip right over the negative.
An optimistic attitude is not a luxury(奢侈品); it’s a(n) ______. The way you look at life will determine how you feel, how you perform, and how well you will get along with other people. ______, negative thoughts, attitudes, and expectations ______themselves; they become a self-fulfilling prophecy(预言). Pessimism creates a dark place where no one wants to live.
Years ago, I drove into a service station to get some gas. It was a beautiful day, and I was feeling great. As I walked into the station to pay for the gas, the attendant said to me, “ How do you feel?” That seemed like a(n) ______question, but I felt fine and told him so. “You don’t look well,” he replied. This ______me completely by surprise. A little ______confidently, I told him that I had ______felt better. Without hesitation, he continued to tell me how bad I looked and that my skin appeared yellow.
By the time I left the service station, I was feeling a little ______. About a block away, I ______over to the side of the road to look at my face in the mirror. How did I feel? Was I affected with jaundice(黄疸)? Was every all right? By the time I got home, I was beginning to feel a little nauseous(恶心). Did I have a bad liver? Had I ______some rare disease?
On another beautiful day, when I went into that gas station, feeling ______again, I figured out what had happened.
