In the middle of the Pacific Ocean lies the tiny island nation of Tuvalu，the fourth smallest country in the world. This group of four islands and five atolls (islands made from coral) is famous for its sandy beaches and turquoise (蓝绿色的) waters and has long been a popular tourist destination for nearby New Zealanders. However, the nation of Tuvalu is at risk of soon no longer existing; not because of war or political change, but because it will be covered by the rising ocean.
Tuvalu is experiencing the harmful effects of global warming. As global temperatures rise, so does the ocean temperature. Due to the scientific law of “thermal expansion,” when water heats it get bigger. 1. Most experts claim that the effects of climate change will make Tuvalu uninhabitable within the next 50 years. Problems are already emerging. As sea levels rise, ocean water containing high levels of salt is travelling further and further inland destroying the little amount of soil Tuvaluans have to grow crops.
Even before Tuvaluans began to suffer from the effects of climate change, lift on Tuvalu was tough. 2. Most of the land on an atoll is rock-hard arid any soil that exists on it is usually thin and poor for growing crops. The nation has always had to import food apart from fish.
More serious than Tuvalu’s lack of home-grown food has been its lack of drinking water.3. Therefore, Tuvaluans depend almost entirely on rainwater for their water needs. Unfortunately, due to a geographical phenomenon known as La Nina, Tuvalu often suffers from long periods of drought. In autumn 2010, after seven months of no rain, the Prime Minister had to declare a state of emergency riot only because of a lack of drinking water, but also because the water left was polluted with cholera (霍乱) 4.
Tuvalu’s problems have led some of its 11, 000 inhabitants to consider migrating to Australia or New Zealand.5. They know they’ll have to someday, but for as long as possible, they want to remain and make the world aware of what is happening to their homeland due to chimate change.
A. It was a desperate situation and, but for emergency shipments from New Zealand and Australia, many Tuvaluans would have died.
B.This is largely due to the geological makeup of atolls.
C. Unlike normal islands, atolls have no rivers or streams, which means that most of Tuvalu has no groundwater to use for drinking.
D. Tuvalu’s representatives demanded that nations should take a more responsible rote in reducing gas emissions.
E. Therefore, sea levels are rising and for low-lying Tuvalu, this spells disaster.
F. However, they ate not willing to abandon the land of their forefathers so easily.
G.And as a member of the United Nations, they are doing just that.
One step too far
Scientists have been trying to figure out how to alter the genes of humans for many years now, and it looks like they've finally cracked (破解) the code. But while this may seem like a great step forward in science, some also believe that it's one step back when it comes to ethics.
In August, a group of scientists from the US and South Korea worked together to successfully edit a human embryo and remove a genetic mutation (突变) that would have led to heart disease, reported The Guardian.
This was achieved with the help of CRISPR, a gene-editing tool that allows scientists to “cut and paste” human DNA.
Although this was the first example of an embryo's genes being changed successfully, the benefits of gene editing have already been tested in living patients.
In 2015, a five-month-old girl from the UK was saved after doctors used edited cells to fight off her cancer. As of today, she's alive and well.
And in the US last year, scientists managed to remove HIV cells from several patients by editing the genes inside their bodies.
Some people hope that in the future, diseases or birth detects could simply be “edited out”. However, others believe this could lead to so-called designer babies, giving parents the option to choose everything from eye color to intelligence.
“You could find wealthy parents buying the latest ‘upgrades’ for their children, leading to even greater inequality than we already live with,” Marcy Darnovsky, director of the San Francisco Center for Genetics, told BBC News.
In spite of these ethical concerns, experts say it’s not possible to create the “perfect” human being. Despite the progress scientists have made, we don’t understand human genes enough to give all unborn child great brainpower or amazing singing abilities.
“Right now, we know nothing about genetic enhancement,” Hank Greely, a director of sciences at Stanford University, US, told The New York Times. “We’re never going to be able to say, honestly, ‘This embryo looks like it would score high on the two-part SAT.’”
So it looks like if we want good exam results, or to impress people with our piano skills, we’ll have to stick with the old fashioned method of plain hard work — at least for now.

4.What can we conclude from the text？ ______
A.Gene editing is regarded as the perfect way to treat birth defects.
B.There is still a long way to go to fully understand human genes.
C.Gene editing could help enhance human intelligence in the near future.
D.Scientists are pessimistic about the future of gene editing.
Morgan Holmes had taken part in Boy Scouts of America activities for a few years, but she only became a full member recently.
This was because the Boy Scouts began accepting girls from fifth grade to 12th grade into a new program called Scouts BSA. It brings girls the opportunities boys have, including becoming Eagle Scouts, the highest rank of the Boy Scouts.
“I'm loving it,” Morgan, now 17, said. “I finally get to wear the uniform now.”
Six middle school girls have joined Morgan in Troop48 in Scouts BSA. Some were members of Girls Scouts, and some have brothers in the Boy Scouts.Now brothers and sisters can take part in activities.
Morgan knows Boy Scouts activities well. Starting when she was 14, Morgan went on high-adventure outings like hiking 100 miles and shooting guns. But she’d never been able to progress to become an Eagle Scout.
Now Morgan’s goal is to reach the top rank of Eagle Scout.
She regularly runs a mile to build up her body. Now, she’s planning on camping in the snow.
“The journey to get there is really exciting,” she said.
Since Boy Scout activities are led by the Scouts themselves, Morgan, as the oldest girl, will be organizing activities and teaching the girls to tie knots and other skills.
One of those girls in Troop48 is Nicolette Ulrich, who is also in the Girl Scouts.
Her mother, Sasha Ulrich, said she sees, the Boy Scouts as more leadership oriented and the Girl Scouts as more culturally oriented.This will be shown by all upcoming gathering where girls will learn about different food and cultures from around the world.
“Girl Scouts is a great group and she’ll continue to do that.” Sasha said. “But she also wanted the opportunities provided by the Boy Scouts.”
1.What did Morgan want to do after becoming a full member of Boy Scouts？ ______
A.She wanted to join in the activities with her brother.
B.She wanted to challenge herself to become all Eagle Scout.
C.She wanted to compete with boys in all activities.
D.She wanted to hike long distances and shoot guns with boys.
2.What is the best word to describe Morgan？ ______
A.Communicative
B.Helpful
C.Creative
D.Adventurous
3.What does Sasha Ulrich think of Boy Scouts？ ______
A.It is more culturally oriented.
B.It helps to build teamwork.
C.It helps to improve leadership.
D.It is more interesting than Girl Scouts.
People back in the United States are always asking me, “What's it like to live in China?” They hope to hear strange stories about weird food and cultural conflicts. Instead, I tell them that living in China is like being a baby.
Please don’t misunderstand me. I don’t think that Chinese people are babies. I am a baby. Or at least, I become one when I leave my house. That’s because babies can’t read, and when I leave my house in Beijing, I’m illiterate (不识字的).
This can be dangerous. If a sign says, “Watch out for big angry bears,” in Chinese, I will continue walking, completely ignorant of my peril (危险). Then a bear will eat me for breakfast.
I have started to recognize a few characters, but they seem impossible to ever learn without a lifetime of study. When I see a character I like. I give it a name. There is “The Square,”“The Octopus(章鱼) ,”“The-upside-down Octopus,” and my favorite, “Upside-down Octopus on an airplane.” However, I still don't know their sounds or meanings.They are just beautiful mysteries to my eyes.
Because I can’t read, city streets present an endless series of enigmas. If I see a business, I wonder, “Is that a restaurant? A dentist? A lawyer’s office?” Once, while hungry, I saw a big colorful sign. I walked in and asked a realtor (房屋中介) to see the drink menu.
Speaking of menus, eating at restaurant is a daily misadventure. Many places have photos of food, which is helpful. But if they have no photos, I walk from table to table and point at whatever looks delicious. I apologize if I’ve ever interrupted your dinner to point at your plate. I didn’t mean to be rude. I was just a hungry baby!

The Breakfast Club
Starred by John Hughes, 1985
Five high school students with nothing in common are forced to spend an entire Saturday together in detention (拘留). At seven a.m. they had nothing to say, but by four p.m, they had bared their souls to each other and became good friends — the Jock, the Brain, the Criminal, the Princess, and the Kook.They were finally able to talk about themselves while they were forced to stay together.
