Mrs. Walker sat down at her desk and sighed. “OK. Tell me, Winston, how your homework became part of the ecosystem.”
“Yesterday,” he began, “after I finished my math homework, I needed a(n) _________. So I took out my bubblegum tape(泡泡糖) to _________. Michael and I are having a contest.”
“Yes.” _______ Michael, “We are.”
“I thought the more gum, the bigger the bubble. I kept _______ gum and my bubble kept growing. Pretty soon I was blowing bubbles so big they _______ my face.”
“Wow!” one girl behind him exclaimed in whisper.
“Then it _______ . I blew a bubble as big as a beachball.” He _______ his arms over his head to show how big it was.”
Some kids murmured in disbelief. But Winston _______ them and went on.
“All of a sudden a gust of wind _______ the bubble right out of my mouth! The bubble ________ over my desk and out the window. As it sailed away, I noticed something yellow stuck to it. Like paper. Then I noticed my ________ was missing.”
“So?” Mrs. Walker asked.
“I ran after it into Mrs. Roosevelt’s garden—she lives next door. I saw her cat ________ the bubble. The bubble broke. All I saw then was the cat running madly away.
“Mrs. Roosevelt helped me search the ________. But my homework was nowhere to be seen.”
Mrs. Walker did not look ________ . Shaking her head, she said, “________ , Winston, why didn’t you just tell me that the homework was __________ and…”

With the development of technology and economy, social media is becoming one of the fastest-growing industries in today’s world. A study conducted by the US Pew Research Center showed that 92 percent of teenagers go online daily. 1.
Changing relationships
High school student Elly Cooper from Illinois said social media often reduces face-to-face communication. “It makes face-to-face relationships harder because of people s attention given to their phones instead of their friends,” Cooper said.
2. Beth Kaplan from Illinois met her long-distance friend through social media. He currently lives in Scotland, but they’re still able to frequently communicate with each other. “I can feel close to someone that I’m talking to via FaceTime,’’ Kaplan said.
Wanting to be “liked”
3. The 19-year-old Essena O’Neill announced on the social networking service Instagram that she was emitting social media because it made her unable to stop thinking about appearing perfect online. 4. Teenagers who get negative comments can’t help but feel hurt.
5.
However, Armin Korsos, a student from Illinois, takes advantage of the comments he receives over social media to improve his videos on the social networking site YouTube. “Social media can help people show themselves and their talents to the world in a way that has never been possible before,” Korsos said.
A. Opening new doors.
B. Teenagers’ attitude toward social media
C. However, the social media is beneficial to long-distance friends.
D. The rise of social media has changed the way teenagers see themselves.
E. Negative comments can also do great damage to a teenager’s self-respect.
F. The wide spread of social media has changed nearly all parts of teenagers’ lives.
G. Yet, some think with social media, it’s easier to start relationships with anyone from anywhere.
Since the sex of a sea turtle(海龟)is determined by the heat of sand hatching the eggs, scientists had suspected they might see slightly more females. Climate change, after all, has driven sea temperatures higher, which, in these creatures, favors female children. They found female sea turtles from Raine Island, the Pacific Ocean's largest and most important green sea turtle living area, now outnumber males by at least 116 to 1. "This is extreme," says turtle scientist Camryn Allen.
Biologist Michael Jensen wanted to know if climate change had already changed turtles' sexes. By using genetic(基因的) tests, he'd figured out that he could follow turtles of all ages. Still, his research data would lack an important detail: sex. Only after a turtle matures is it possible to tell its sex from the outside -- mature males have slightly longer tails. By then turtles can be decades old, so scientists often use Iaparoscopy(腹腔镜检查)，sending a thin tube into each animal, but that's not so practical if you're hoping to examine hundreds of creatures. Fortunately, at a turtle conference, he met Allen, and all she needed was a little blood.
They compared their results with temperature data for nesting beaches. What worries them is that Raine Island has been producing almost female turtles for at least 20 years. This is no small thing. More than 200,000 turtles come to nest there. During high season, 18,000 turtles may settle in at once. "But what happens in 20 years when there are no more males coming up as adults? Are there enough to maintain the population?" says Allen. They also found cooler beaches in the south are still producing males, but that in the north, it's almost entirely females hatching. These findings clearly point to the fact that climate change is changing many aspects of wildlife biology.
But how widespread is this phenomenon -- and what is the consequence?
1.How might the scientists feel if there were slightly more female turtles?
A. It's normal. B. It's unique. C. It's extreme. D. It's doubtful.
2.What is a scientist's conventional way to identify a turtle's sex?
A. Testing its blood. B. Doing genetic tests.
C. Using laparoscopy. D. Watching its tail.
3.Why do the findings worry Jensen and Allen?
A. Too many females gather near Raine Island. B. Sea turtles may end up dying out.
C. Turtle populations are in decline. D. Female turtles cause temperatures to rise.
4.What does the last paragraph imply?
A. People should stop the phenomenon.
B. People have to test the consequence.
C. Climate change has changed sea turtles' sexes.
D. More work needs doing about the phenomenon.
Since English biologist Charles Darwin published On the Origin of Species in 1859, scientists have vastly improved their knowledge of natural history. However, a lot of information is still of the speculation, and scientists can still only make educated guesses at certain things.
One subject that they guess about is why some 400 million years ago, animals in the sea developed limbs (肢) that allowed them to move onto and live on land.
Recently, an idea that occurred to the US paleontologist (古生物学家) Alfred Romer a century ago became a hot topic once again.
Romer thought that tidal (潮汐的) pools might have led to fish gaining limbs. Sea animals would have been forced into these pools by strong tides. Then, they would have been made either to adapt to their new environment close to land or die. The fittest among them grew to accomplish the transition (过渡) from sea to land.
Romer called these earliest four-footed animals “tetrapods”. Science has always thought that this was a credible theory, but only recently has there been strong enough evidence to support it.
Hannah Byrne is an oceanographer (海洋学家) at Uppsala University in Sweden. She announced at the 2018 Ocean Sciences Meeting in Oregon, US, that by using computer software, her team had managed to link Homer’s theory to places where fossil deposits (沉积物) of the earliest tetrapods were found.
According to the magazine Science, in 2014, Steven Balbus, a scientist at the University of Oxford in the UK, calculated that 400 million years ago, when the move from land to sea was achieved, tides were stronger than they are today. This is because the planet was 10 percent closer to the moon than it is now.
The creatures stranded in the pools would have been under the pressure of “survival of the fittest”, explained Mattias Green, an ocean scientist at the UK’s University of Bangor. As he told Science, “After a few days in these pools, you become food or you run out of food... the fish that had large limbs had an advantage because they could flip (翻转) themselves back in the water.”
As is often the case, however, there are others who find the theory less convincing. Cambridge University’s paleontologist Jennifer Clark, speaking to Nature magazine, seemed unconvinced. “It’s only one of many ideas for the origin of land-based tetrapods, any or all of which may have been a part of the answer,” she said.

A. Hannah Byrne. B. Charles Darwin. C. Steven Balbus. D. Alfred Romer.
2.Why were tides stronger 400 million years ago than they are today according to Steven Balbus?
A. There were larger oceans. B. Earth was under greater pressure.
C. Earth was closer to the moon. D. The moon gave off more energy.
3.The underlined word “stranded” in Paragraph 8 probably means “________”.
A. settled B. trapped C. abandoned D. found
4.What is the focus of the article?
A. The arguments over a scientific theory.
B. The proposal of a new scientific theory.
C. Some new evidence to support a previous theory.
D. A new discovery that questions a previous theory.
