The sky is large place, and though it has been carefully examined for centuries, new features still turn up. Last March it was the rule of Uranus (天王星), and last week astronomers announced what may turn out to be a new planet, though a very small one, in the solar system.

    The object was first sighted last month by Charles Kowal, an astronomer at the Hale Observatories in Pasadena, Calif. Mr. Kowal observed a faint trail of light on photographic plates, indicating that something was moving in relation to the background of stars. Other observers have confirmed the discovery.

    The “mini-planet”, identified for the time being as “Object-Kowal”, appears to be about 1.5 billion miles away, between the orbit of Saturn and Uranus, and its diameter (直径) has been estimated at between 100 and 400 miles. Its orbit has not been determined yet, but if the orbit proves to be roughly circular, like that of the major planets, the new object would probably take 66 to 70 years to make a circuit of the sun.

    Some astronomers have speculated that Mr. Kowal's discovery may be the first indication of an asteroid (小行星) belt beyond Saturn.

    We walked in so quietly that the nurse at the desk didn't even lift her eyes from the book. Mum pointed at a big chair by the door and I knew she wanted me to sit down. While I watched, mouth open in surprise, Mum took off her hat and coat and gave them to me to hold. She walked quietly to the small room by the lift and took out a wet mop (拖把). She pushed the mop past the desk and as the nurse looked up, Mum nodded and said, "Very dirty floors."

    "Yes, I'm glad they've finally decided to clean them," the nurse answered. She looked at Mum strangely and said, "But aren't you working late?"

    Mum just pushed harder, each swipe of the mop taking her farther and farther down the hall. I watched until she was out of sight and the nurse had turned back to writing in the big book.

    After a long time Mum came back. Her eyes were shining. She quickly put the mop back and took my hand. As we turned to go out of the door, Mum nodded politely to the nurse and said, "Thank you."

    Outside, Mum told me, "Dagma is fine. No fever. "

    "You see her, Mum?"

    "Of course. I told her about the hospital rules, and she will not expect us until tomorrow. Dad will stop worrying as well. It's a fine hospital. But the floors! A mop is no good. You need a brush. "

    2.26-meter-tall Yao Ming made his NBA debut (初次登台) on October 23, 2002 and got 6 points for the Houston Rockets in the game. The next day, he got 13 points in another game.

    Most people think that Yao Ming is a born basketball player. But Yao said, "When you watch it on TV, it looks very easy. But when you are playing in the NBA, it is really not so easy." He said that joining the Houston Rockets was a new start and a new challenge. "I hope that through very hard work I can make everyone happy and help the Rockets win more games," he said. Yao Ming speaks some English. Both he and his teammates can understand each other. They don't think there is a language problem. While Yao Ming faces this new challenge, the people of Houston have shown great interest in him and they hope Yao Ming will bring new energy to the Rockets. The team has started having lessons to learn more about China, and many people who work for the Rockets have learned to speak some Chinese.

    Better known by his stage name Kun, Cai Xukun is, without a doubt, one of the most popular stars in China.

    On July 26, the 21-year-old dropped his new single Young. Within just 20 seconds, it reached 1 million views and in only 3 days topped the music charts of Tencent's QQ music.

    Cai wrote the song by himself to share his understanding of modern-day youth. The singer has mixed R&B with electronic music to make his new beat cheerful. One reviewer wrote on QQ Music: "When you listen to the song, you just seem to go back to youth again."

    August 2 is Cai's birthday, and the song was a gift to himself. The singer hopes that he can always have the courage to follow his love of music, ignoring what anyone says. "My works are like my children and I have put my best effort into them. I want every piece of my work to have my own spirit in it. I feel more enjoyment when I am performing my own work." He told the Global Times.

    To find new inspiration, Kun attends different kinds of musical performances－from festivals to opera houses. "I just like to do everything, all for my music, all for my art," he told i-D.

    With talent and dedication(专注) to music, Cai is expected by many to make his mark in the competitive Chinese music industry.

A storm hit Houston, Texas, on Tuesday. It brought heavy rains and rising flood-waters. By Tuesday night, some parts of the city had received 10 inches of rain. Police and firefighters helped people move to safe places. They also saved people from cars and buses that were stuck on roads.

Certain areas around Houston were hit really hard. In just four hours, more than seven inches of rain fell in Sugar Land in the southwest of Houston. Cars could not pass through any of the areas main roadways. On Twitter, Sugar Land city officials asked people to get to high ground.

Tuesday's rain hit parts of Texas that Hurricane Harvey had already damaged almost two years ago. Hurricane Harvey in August, 2017 was the second most costly hurricane in US history. It caused $125 billion worth of damage in Texas. In the Houston area, 36 people died and about 150, 000 homes were flooded.

A spokesman for the Harris County Office of Homeland Security and Emergency Management spoke with the Houston Chronicle. The spokesman said that this week's rain is "not in any way a Harvey-level event."

But the worst may not be over yet. People will have a break from the heavy rain on Wednesday. According to the National Weather Service, the Texas Gulf Coast will continue to experience heavy rain later in the week. "Today should be our quietest over the next few days for rainfall," said Don Oettinger, a National Weather Service meteorologist (气象学家).

Houston Fire Chief Samuel Peia warned, "As there is too much water on the ground, these are perfect conditions for flash floods, so we hope people are careful of what they're doing and encourage them to stay home. There's no sense in putting yourself, firefighters or anybody in danger needlessly."

Here are the Disney movies recommended by Brandon Dammit for this weekend. 

Fantasia 2000

Budget: $80 million

Score: 75%

I remember disliking Fantasia 2000 in theaters as a young child, but I have developed a much deeper appreciation for the fantastic music as an adult. Disney has employed advanced sound tools to produce a movie that was under-appreciated at its first appearance.

Pete's Dragon

Budget: $65 million

Score: 60%

I love Disney as much as the younger generation. But it's disappointing to see flavorless remakes like The Lion King and Beauty and the Beast harvest billions at the box office while more soulful remakes like Pete's Dragon is largely ignored. 

The Rescuers Down Under

Budget: $38 million

Score: 70%

I won't lie to you, kind reader. The Rescuers Down Under is the only movie that I've never seen here and my honor won't allow me to pretend otherwise. According to Disney, it's about the world's bravest mice, Bernard and Bianca, who race to Australia to save a boy and a rare golden eagle from a cruel hunter. So, you know, normal Disney stuff. 

The Great Mouse Detective

Budget: $14 million

Score: 72%

Picture this: a young mouse named Olivia is committed to discovering the truth of her father's disappearance in 1897 London, and she got the help from his friends, Dr. Dawson and Toby. It's basically Disney's Sherlock Holmes.
