Zhurong, China’s first Mars rover, sends back a photo of the planet’s surface.On May 15, China’s Tianwen 1 probe made a historical landing on Mars! People all over the world applauded the successful landing, as it was very hard to pull off.In July 2020, Tianwen 1 was launched from the Wenchang Space Launch Center. In February, the probe entered Mars’ orbit. Experts said the difficulty of sending the probe into orbit was equal to hitting a golf ball from Paris and landing it in a hole in Tokyo. But it still couldn’t match the difficulty of the final landing stage, which is also called the “nine minutes of terror(恐怖)”. How did Tianwen 1 do it? Let’s take a look.Nine minutes of terror:Within nine minutes, the probe had to slow its speed from 20,000 km per hour to zero, landing from 125 km above Mars. Since the probe was 320 million km away from Earth, there was a signal delay (延迟) of over 10 minutes if the research team tried to control it from Earth. So the probe had to carry out the landing by itself!The drag(空气阻力) created by the atmosphere slowed it down first. During this process, the surface of the craft heated up to 2,100°C, which could melt the craft! Fortunately, it had a heat shield(抗热涂层) to protect it.Next, a parachute(降落伞) opened to further reduce the craft’ s speed. This was also a dangerous process, as the parachute’ s ropes could break due to(由于) the craft’ s high speed. Researchers used special materials to make the ropes strong enough to stay in one piece.At 1.5 km above Mars, the craft fired its retrorockets(反向火箭) as another way to help it slow down. At 100 meters, the craft stayed in the air and used its sensors(传感器) to check the landing area. It had to move away from obstacles(障碍物) such as rocks before finally touching down.Following the US and Russia, China is now the third country in the world to successfully land a probe on Mars. It will give Chinese scientists their first opportunity to closely study the Red Planet, Tianwen 1 makes it to Mars.1. The underlined phrase “pull off” in paragraph 2 is closest in meaning to “____”.2. What does the underlined sentence in paragraph 3 probably mean?3. Why did China launch the Tianwen 1 probe?4. Which statement is NOT true according to the passage?5. This passage is most likely to appear in ______.

In a time when it’s so easy to feel isolated, all of us need to feel seen and heard. But these two neighbors could only hear each other first. Back in January, Giorgio posted a video on TikTok about his new neighbor. The post began a series of clips over the next month that showed that the two neighbors played out together in the form of two pianos separated by one wall. Giorgio started their friendship by writing a note to his neighbor, thinking highly of the stranger on his wonderful skill and asking him to perform a song: My Heart Will Go On. The next day, the song was heard through the wall, and Giorgio was both touched and overjoyed. Their note exchanges soon turned into piano duets through the wall.They continued doing their piano duets every weekend around 2 p.m., until Giorgio finally got the chance to meet his partner face-to-face. “Well, today I have met my neighbor and let me tell you it was better than expected,” Giorgio wrote. “His name is Emil. He is 78 years old, originally from Poland. He lost his wife last December due to COVID-19, and all he has left is the piano.”Giorgio went on to explain that Emil’s reason for playing every weekend at 2 p.m. was that his wife always loved it at that time. Emil was quick to thank Giorgio for giving him company, friendship, and the motivation to keep playing. That’s when Giorgio added, “I promised that I’ll play with him until he moves out.” And so he did!Though Emil’s time in this apartment was short before he left for some reason, the friendship became a memory to last a life time.1. What was the video Giorgio posted about?2. Why did Giorgio write a note to his neighbor?3. Giorgio’s neighbor loved to play the piano at 2 p.m. every weekend because ____.4. Which of the following can best describe this story?5. What is the best title for the passage?

Reading is the key to school success and, like any skill, it takes practice. A child learns to walk by practicing until he no longer has to think about how to put one foot in front of the other. A great athlete practices until he can play quickly, accurately(准确的), without thinking. Tennis players call that “being in the zone.” Educators call it “automaticity.”A child learns to read by sounding out the letters and decoding the words. With practice, he stumbles less and less, reading by the phrase. With automaticity, he does not have to think about decoding the words, so he can concentrate on the meaning of the text.It can begin as early as the first grade. In a recent study of children in some schools, Alan Rossman of Northwestern University found automatic readers in the first grade who were reading almost three times as fast as the other children and scoring twice as high on comprehension tests. At fifth grade, the automatic readers were reading twice as fast as the others, and still outscoring them on accuracy, comprehension and vocabulary.“It’s not I.Q. But the amount of time a child spends reading that is the key to automaticity.” According to Rossman, any child who spends at least 3.5 to 4 hours a week reading books, magazines or newspapers will in all likelihood reach automaticity. At home, where the average child spends 25 hours a week watching television, it can happen by turning off the set just one night in favor of reading.You can test your child by giving him a paragraph or two to read aloud something unfamiliar but appropriate to his age. If he reads aloud with expression, with a sense of the meaning of the sentences, he probably is an automatic reader. If here ads haltingly(断续的), one word at a time, without expression or meaning, he needs more practice.1. The first paragraph tells us____.2. When a child starts to read, how does he do this?3. A recent study in some schools reveals that the automatic reader’s high-speed____.4. A bright child____.5. The main idea of this paragraph is____.
