Do you know Mirror Test? In short, the test is to put a mirror in front of an animal to see whether the animal has self-awareness (自我意识). It is done by watching the interaction (互动) between the animal and itself in the mirror. Cleaner fish can recognize themselves in a mirror when moving around. This means that they have self-awareness and passed the mirror test.
However, in a new study, cleaner fish were believed to tell their own face in still pictures. They can’t move. In the study, researchers showed 10 fish a photo of their own face first. And then they showed a photo of a cleaner fish which is strange to them. All the fish acted aggressively(攻击性地) toward the second one, but were not aggressive toward the photo of their own face.
Researchers explain why this would happen. They think that in the beginning, the fish possibly see the movement of the animal in the mirror, which matches their own movement. Then the fish form an image of their own face in their mind. In this way, they learn to know themselves.
1. What can we get through the test according to the first paragraph?| A．Cleaner fish feel very strange. |
| B．Cleaner fish is very afraid. |
| C．Cleaner fish have self-awareness. |
| D．Cleaner fish can’t recognize themselves in a mirror. |
| A．仍然的 | B．游动的 | C．好奇的 | D．静止的 |

【推荐1】Do stars only appear at night? The answer is no. Venus (金星) is the only star that can be seen in daytime. It shone at its brightest in the night sky on Feb 17 this year.
Venus is the second planet from the sun. It is the second brightest natural object, behind the earth’s moon, in the night sky. Why is it so bright?
First of all, Venus is the closest planet to the earth. It is also covered by highly reflective (反射的) clouds, which can reflect about 70 percent of the sunlight striking (照射) it, almost twice as much as the earth does. Some people call 2017 the year of Venus, because the planet is at its brightest twice this year. Venus gets brighter when it goes further away from the sun, and nearer to the earth. The brightest moment happened once in February, and will happen again, during daylight, on April 30.
If Venus is so bright and close to us, isn’t it a better choice for human exploration (探索) than Mars? It is closer to the earth than Mars and it’s closer to the earth in size. The closer distance to the sun means solar power (太阳能) would be easier to generate as well.
However, with a temperature of about 465℃ on the surface, Venus is the hottest planet in our solar system!
But scientists never give up. Recently, a team of NASA and Russian scientists created new computer equipment that can stand temperatures of 480℃. It can work under Venus-like conditions (环境) for almost 22 days.
The next step, according to the scientists, is to send a probe (探测器) to Venus by 2025.

【推荐2】To us, it seems so natural to put up an umbrella to keep the water off when it rains. But in fact the umbrella was not invented as protection against the rain. Its first use was as a shade (遮蔽) against the sun.
Nobody knows who first invented it, but the umbrella was used in very ancient times. Probably the first to use it were the Chinese, back in the eleventh century BC.
We know that the umbrella was used in ancient Egypt and Babylon as a sunshade. And there was a strange thing connected with its use: it became a symbol of honor and power. In the Far East in ancient times, the umbrella was allowed to be used only by those in high office or by royal people such as the kings or queens.
In Europe, the Greeks were the first to use the umbrella as a sunshade. The umbrella was in common use in ancient Greece, but it is believed that the first people in Europe to use the umbrella as protection against the rain were the ancient Romans. During the middle ages in Europe, the use of the umbrella almost disappeared. Then it appeared again in Italy in the late sixteenth century. And again it became a symbol of power.
Umbrellas have not changed much in style during all this time, though they have become much lighter in weight. It wasn’t until the twentieth century that the umbrellas for women began to be made in all kinds of colours.
1. According to the passage, the umbrella was probably first used in ancient _______.| A．Egypt | B．Babylon | C．Rome | D．China |
| A．The ancient Greeks used the umbrella in their daily life. |
| B．Europeans hardly used the umbrella during the middle ages. |
| C．The umbrellas for women were made colourful in ancient times. |
| D．The style of the umbrella hasn't changed a lot since it was invented. |
【推荐3】There are over 30,000 kinds of spiders in the world today. Many people may think spiders are part of the insect family, but it is not a fact. Spiders are different from insects in some ways. For example, spiders have eight legs, eight eyes, two body parts while most insects have six legs, two eyes and three body parts.
A lot of spiders spin webs (结网). But not all of them do. Spiders spin webs to catch insects. After an insect flies into the web, the spider eats it.
Here are some spiders that do not spin webs.
Trap-Door Spider
A trap-door spider digs a small hole in the ground. It covers the hole with a door. Then the spider waits for an insect to walk by. When one is near, it jumps out of the hole and catches the insect.
Jumping Spider and Wolf Spider
Jumping spiders and wolf spiders walk around on plants on the ground. When they find an insect, they jump on it, just as a cat catches a mouse.
Crab Spider
Crab spiders live on flowers. They wait for insects that come to the flowers to find food. Then the spiders catch the insects and eat them.
Water Spider
Water spiders live in the water and are good at swimming. They build a bubble (气泡) home themselves. They catch insects that live in the water. They carry the insects back to their home, where they eat them.

Very often, new-born babies are not beautiful. They are wrinkled(多皱的)or hairless, or they have an angry look on their faces. They seem to say, “Get away! I hate everybody.” But to a parent, that hairless, wrinkled, angry-faced baby is the most beautiful and perfect child in the world. When that proud father or mother asks you, “Well, what do you think of my baby? Isn’t she beautiful?” what are you going to say? Is the time for the true? Of course not!
You look that proud father in the eye and say, “Yes, she is! She’s really a beauty. She’s one in a million. She’s going to be a movie star! I can tell! She’s as beautiful as a picture.”
In English, this is a white lie. White lies don’t hurt people. They are not cruel(残忍的)or angry words. People use them to make a difficult thing a little easier. When people don’t want to meet someone, or eat something new that they really don’t like at a friend’s house, they tell a white lie. They are trying to be kind. They don’t want to hurt someone. It’s important to be honest, but many people feel that being kind is sometimes more important.

【推荐3】Nina is reading a book which described 37 endangered natural and cultural treasures in the world. The writers want the book to be a hopeful call to action. Let’s visit some of these places.
Venice
The ancient city of Venice, Italy has long been threatened (威胁) by rising sea levels because of the warm temperature. The situation is made worse by the fact that its ancient buildings, built on a body of water, are slowly sinking (下沉). When the city was founded about 1,600 years ago, the level of Adriatic Sea was almost 2 meters lower than it is today.
Mount Kilimanjaro
Mount Kilimanjaro in northeastern Tanzania, is the highest in Africa, almost 6,000 metres. The mountain supports 5 plant areas and many kinds of animals. The ice glaciers (冰川) on the mountain are disappearing very quickly. This will have a bad effect on the mountain’s ecosystems (生态系统) and on Tanzania’s travel industry. Also, a valuable record of thousands of years of weather history will also be lost if the ice melts.
Glacier National Park
In the United State, the icy blocks in Clacier National Park may soon completely disappear because of weather change. In 1850, there were about 150 glaciers. There are 26 glaciers remaining today. Scientists estimate that the glaciers will be gone by 2030. Warm temperatures are also threatening the many kinds of plants and animals that live in this mountain ecosystem.
Great Barrier Reef
The Great Barrier Reef in Australia is the largest coral reef (珊瑚礁) system in the world. Rising sea temperatures are greatly harming the reef. In some areas, healthy yellow, brown and green reefs have become white. The coral whitens when it is in warmer temperature. Sick or dying coral influences the whole ecosystem of this special underwater area. Water pollution and visits by careless swimmers and divers also threaten the reef.
1. What does the common harm to the four places above according to the text?| A．Sea levels. | B．Ice glaciers. | C．Warm temperature. | D．Water pollution. |
