Why should most of us hate spiders when we know deeply how much good they do? Is it because they somehow seem so alien? After all, what other land creatures on earth have eight legs? What other creatures spin silk webs in which to catch and wrap their prey to preserve it for the future, much as we put food in the fridge to eat later? I do not personally suffer from arachnophobia, the name given to an abnormal fear of spiders, but I can't say that I like the little beasts. However, some people do, and they actually keep them as pets!
There is a wide variety of spiders in the world. In fact it has been estimated that there are some 35,000 species——from little "money spiders" that live in your back garden, to the "black widow spider", and the “tarantula” ，the spider that is now sometimes kept as a pet.
A tarantula can be any one of a large hairy spiders family and there are about 800 species of them. While experts can tell the difference between species at a glance, most are usually described in reference books as “rather slowly" with “a strong bite which may be poisonous”. They are covered with hairs which can cause a rash （皮疹）if they are handled.
No one has calculated the number of human deaths caused by a bite from a tarantula perhaps because it has never happened, or happened so rarely, and indeed a tarantula will do no harm to anyone if handled correctly. Their disgusting image cannot belie their gentle nature but experts tell us not to handle a tarantula without expert advice.
Tarantulas are popular as pets and it requires very little space to maintain them in excellent condition. They should be kept singly in a glass container, which need not be very large but should have a layer of stones in the bottom. They feed on insects, and while young tarantulas eat twice a week, adults will often eat no more than once every 10 days.
You might like the idea of keeping a tarantula, but personally I am content with just watching them at a distance.

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 Change 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（探测雷达）. 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 180kilometers 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.Its signals could reach 40 meters beneath the moon’s surface.
D.It is three times as large as the Change 3 lunar probe.
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.According to the passage, why is the Chang’e 4 probe exploration is important?
A.It observed material beneath the moon’s surface which is helping scientists to know the moon better.
B.It has offered us relevant information on the near side of the moon.
C.It told scientists the landing site is very complex.
D.It revealed the surface material on the moon which is helpful to know the moon’s activity and impact.
4.What is the Chang’e 5 probe expected to do?
A.Explore the Von Karman crater.
B.Replace Yutu 2 to explore the moon.
C.Identify the moon’s various layers.
D.Bring lunar samples back to the Earth.
5.What is the text mainly about?
A.A history of Chinese lunar missions.
B.How Yutu 2 explored beneath the moon’s surface.
C.report on the Chang’e 4 probe’s findings.
D.A comparison of the Change 3 and 4 probes.

When Should a Leader Apologize and When Not?
Why Difficult?
When we wrong someone we know, even not intentionally, we are generally expected to apologize so as to improve the situation. But when we’re acting as leaders, the circumstances are different. The act of apology is carried out not merely at the level of the individual but also at the level of the institution. It is a performance in which every expression matters and every word becomes part of the public record. Refusing to apologize can be smart, or it can be stupid. So, readiness to apologize can be seen as a sign of strong character or as a sign of weakness. A successful apology can turn hate into personal and organizational harmony—while an apology that is too little, too late, or too obviously strategic can bring on individual and institutional ruin. What, then, is to be done? How can leaders decide if and when to apologize publicly?
Why Now?
The question of whether leaders should apologize publicly has never been more urgent. During the last decade or so, the United States in particular has developed an apology culture—apologies of all kinds and for all sorts of wrongdoings are made far more frequently than before. More newspaper writers have written about the growing importance of public apologies. More articles, cartoons, advice columns, and radio and television programs have similarly dealt with the subject of private apologies.
Why Bother?
Why do we apologize? Why do we ever put ourselves in situations likely to be difficult, embarrassing, and even risky? Leaders who apologize publicly could be an easy target. They are expected to appear strong and capable. And whenever they make public statements of any kind, their individual and institutional reputations are in danger. Clearly, then, leaders should not apologize often or lightly. For a leader to express apology, there needs to be a good, strong reason. Leaders will publicly apologize if and when they think the costs of doing so are lower than the costs of not doing so.
Why Refuse?
Why is it that leaders so often refuse to apologize, even when a public apology seems to be in order? Their reasons can be individual or institutional. Because leaders are public figures, their apologies are likely to be personally uncomfortable and even professionally risky. Leaders may also be afraid that admission of a mistake will damage or destroy the organization for which they are responsible. There can be good reasons for hanging tough in tough situations, as we shall see, but it is a high-risk strategy.

Our sense of hearing is one of the most important means of knowing what is going on around us. We are warned of danger by sounds. The sounds of music please us. Sound has a waste product, too, in the form of noise. Noise has been called unwanted sound. Noise is growing and it may get much worse before it gets any better.
Scientists, for several years, have been studying how noise affects people and animals and are alarmed by what they have learned.
Peace and quiet are becoming harder to find. Noise pollution is no joke. It is a threat that should be looked at carefully.
Sound is measured in units called decibels （分贝）. At a level of 140 decibels people feel pain in their ears.
Trucks, buses, motorcycles, airplanes, boats, and factories all make noise. This noise bothers not only our ears, but our minds and bodies as well.
There is a saying about "it is so noisy that you can't hear yourself think". Doctors who study noise believe that we must be able to hear ourselves think most of the time. If we don't, we may have headaches, other aches and pains, or even mental problems. Noise adds even more tension to a society which already faces too much stress.
49．The sense of hearing _______.
A．makes people feel angry
B．makes people want to dance
C．helps people to know what is happening around them
D．is something harmful to people
50．When sound is turned into noise, _______.

Today we think of Abraham Lincoln as a great leader. What most of us don’t know is that he was a well-known humorist and storyteller in his day.
Lincoln learned to tell jokes and stories from his father. When Lincoln became a lawyer, he used his jokes and stories to gain the good will of the jury (陪审团), and more than once his opposing lawyer would complain to the judge that Lincoln’s stories were irrelevant and distracting (转移、分心) to the jury. The trouble for them was that Judge David Davis loved Lincoln’s jokes more than anyone else in the court room.
As a politician, Lincoln made excellent use of his humorous stories. His long time political opponent Stephen A. Douglas complained that “Nothing else — not any of his arguments or any of his replies to my questions — disturbs me. But when he begins to tell a story, I feel that I am to be overmatched.” More than once Douglas and other political opponents of Lincoln’s saw their well presented arguments forgotten by the audience after Lincoln followed up their speeches with a homely story.
As the responsibilities of the office of President became greater and heavier, Lincoln used humor to find relief. He wanted to reduce the stresses in himself and those around him. One of Lincoln’s neighbors told that one day, he saw Lincoln walking past with two young shouting boys. “What’s the matter, Mr. Lincoln?” the neighbor asked. “The same thing that’s the matter with the whole world,” Lincoln answered. “I have three walnuts, and each one of them wants two of them.”
One cannot truly appreciate Lincoln without understanding his humorous side. He used his jokes and stories both for the purpose of winning over his audience and relieving the pressure he experienced as President during the terrible Civil War.
1.When Lincoln was a lawyer, what was his purpose of telling jokes and stories?
A. He wanted to satisfy the judge’s desire for jokes.
B. He wanted to distract his opposing lawyer.
C. He wanted to relieve his pressure.
D. He wanted to impress the jury.
2.What might be Douglas’ attitude towards Lincoln’s humorous stories?
A. Appreciative. B. Annoyed.
C. Concerned. D. Surprised.
3.What’s the purpose of the text?
A. To educate. B. To inform.
C. To persuade. D. To entertain.
