2 . Many of us think of sharks as powerful, mysterious, and lonely as they move through the deep. And nowonder the fish have long been portrayed in popular media as lone predators, appearing out of nowhere to attack. But that image has come under inspection in recent years, as shark researchers around the world have discovered the fish gathering in large numbers and interacting with others of their own species in ways that are obviously friendly.

Yannis Papastamatiou, a marine scientist at Florida International University, and his team used acoustic transmitters to record the interactions over four years of about 40 reef sharks around Hawaii. Their study found that reef sharks return to the same communities year after year, forming clear preferences for sharks with some friendships that endured throughout the study. In his 2016 study, he found that individual sharks tagged with recording devices had thousands of interactions with their peers, with some pairs spending up to four straight days together. The study also found certain sharks were unmistakably companions. “These weren’t random associations,” he says.

Finding out why sharks socialize — and how much of their behavior is cooperative — is a challenge, but there are some clues, such as food availability and warmer waters. Great white sharks, are showing up in record numbers along southern California beaches as the population has doubled since 1994. While great white sharks typically maintain distances of about 30 feet from each other and don’t seem too close, they are clearly drawn together by a preference for the area. In some cases, there may not be an obvious purpose for shark’s friendship. At the Bimini Shark Lab, Smukall and his colleagues found that young lemon sharks sought out companionship of other sharks for no clear reason. There’s growing evidence that lemon sharks have their own personalities, which may influence whether they spend time with other sharks, he adds.

More would be known about the intimate lives of sharks if the field weren’t so new, due in part to a lack of funding and sharks’ negative reputation. “We’ve only had about 20 years to really start studying sharks,” says Smukall.

1. Why do the reef sharks return to the same groups every year?

A．To move to other places together.	B．To find a better place to lay eggs.
C．To change the food chain of the sea.	D．To search for the company of other fish.

2. Which of the following is NOT the reason why sharks socialize?

A．Global Warming.	B．Preference for an area.
C．Sharks’ personalities.	D．Food availability.

3. What can be found according to Yannis’s 2016 study?

A．Sharks usually spend four days with their peers.

B．The relationship between some sharks is steady.

C．All the sharks were attached to recording devices.

D．Sharks have thousands of interactions every day.

4. What can be inferred from the last paragraph?

A．Sharks always have a bad reputation.

B．Scientist will begin studying sharks in 20 years.

C．There will be a long way to go before knowing sharks completely.

D．It is unnecessary to put money into the research of the sharks.

3 . There are 156 known species of glass frogs living throughout the neotropics. Recent advancements in genetics are giving researchers a revealing look into the lives of these one-inch-long tree dwellers, some of which are the size of a paper clip.

Scientists have discovered, for example, that male glass frogs in some species are stellar parents — a rare trait among vertebrates (脊椎动物). Males of at least 24 species not only protect their eggs from predators but also actively care for them. While the embryos (胚胎) develop, males of some species, such as the sun glass frog sit atop their egg clutch "like a chicken," keeping the eggs hydrated until they hatch into tadpoles (蝌蚪).

New research is also discovering how the glass frog's transparent belly forms. It's suspected that young glass frogs physically rearrange the insides of their cells and tissues to become transparent adults. Fluid between the tissue cells may also contain a substance that allows light to travel through.

Another mechanism that may allow glass frogs to blend into the green leaves on which they doze during the day is called "a biological mirror", a kind of shield or covering of crystals in many of their tissues, which reflects up to 30 percent of the light that normally reaches them. Those crystals amplify the light signal, and the frog's green looks brighter.

Many scientists studying glass frogs arc motivated by the fact that some of their subjects are disappearing—and fast. Agriculture, cattle grazing, and mining projects in the Andes are taking over the frogs' already fractured forest homes.

"As soon as they are discovered, many species are declared endangered," Guayasamin, a biologist in Ecuador, says "yet there could be an advantage in conserving such isolated ponulanons." All could be inspired to work together to set aside frog-rich patches of land as reserves, ensuring that these delicate creatures have a solid chance at survival.

1. What can we know about glass frogs?

A．They are regarded dangerous.	B．They are small animals.
C．They are of different colors.	D．They live in the water.

2. What does the underlined word "stellar" in paragraph 2 probably mean?

A．Strange.	B．Ambitious.
C．Excellent.	D．Different.

3. How can glass frogs hide themselves in the green leaves?

A．They physically change their cells.	B．They contain transparent fluid.
C．Crystals in their tissues reflect light.	D．Light signal makes them greener.

4. What is Guayasamin's suggestion for endangered glass frogs?

A．Stopping cattle grazing.	B．Building frog reserves.
C．Improving frog popularity.	D．Planting more forest trees.

8 . Now is the time to act on climate change. We need to cut carbon emissions (排放), and knowing this, it is easy to be pessimistic. Strangely, I’m feeling the opposite. And that’s mostly because of one factor: Batteries. It isn’t obvious but over the last decade or so, just as we’ve watched our computers get faster and screens get thinner, batteries have greatly improved too.

According to the European Patent Office, the number of battery patents filed grew by an average of 14 percent every year between 2005 and 2018. Energy storage is getting better and better, as more companies are discovering new chemistry and processes to make them work more efficiently.

And the results of all of this work are astonishing. Energy density—the amount of power that can be stored in the same sized battery—has doubled in the last decade. And the costs of batteries have fallen a lot too.

Brilliantly, because electric batteries are improving so noticeably, we can already see the results. Last September, 15 percent of all new vehicle registrations were pure electric vehicles. So the change is starting to happen.

It’s conceivable that in the not-too-distant future, alongside other essentials in our homes like a boiler and a fusebox, we might also have an enormous battery in the garage. This would take power from the grid (电网) or maybe even solar panels on the roof, and power appliances and lights in our homes at the times when demand for electricity is high.

So, given how much technology has improved batteries over the last decade, I can’t help but be strangely optimistic about the future. Batteries may not be as flashy (显眼的) as phones, rockets or other new technologies, but when it comes to technology to fight climate change, they’re definitely leading the charge.

1. What is the author’s attitude towards cutting carbon emissions?

A．Doubtful.

B．Favorable.

C．Unclear.

D．Anxious.

2. What is the possible result of batteries’ great improvement?

A．It’ll make them more environment-friendly.

B．It’ll make people use electricity at will.

C．It will slow the development of pure electric vehicles.

D．It’ll cause the prices of batteries to rise.

3. What does the underlined word “conceivable” in paragraph 5 mean?

A．Unacceptable.

B．Astonishing.

C．Possible.

D．Unreliable.

4. Which of the following is a suitable title for the text?

A．Carbon Emissions Result in Climate Change

B．Now Is the Time to Act on Climate Change

C．How Battery Technology Can Save the Planet

D．How Much Technology Has Improved Batteries

One day my dad came back home in his truck and there was a cage in the back. Naturally I was curious, so I went towards the truck when I noticed that there was a small little goat that wasn’t even an adult yet.

I asked my dad and he said that he bought the goat from his friend and he was going to kill it twenty minutes after he brought it home so that we would have a big meal.

My sister was there too and she was strongly for my view. We found out we got really mad at my dad and told him not to kill it. After about 10 minutes of complaining we finally convinced my dad not to kill it because we told him that there was no reason for him to kill the goat himself when he could just buy goat meat at a store.

My parents know some friends that we visit sometimes and their family really likes animals so we decided to give it to them. For about a month, they had the goat as a pet and they also had the same problems as we had because the dad wanted to kill it and eat it but the rest of the family didn’t want it to die.They also were able to persuade him not to do so. They ended up sending the goat to a family member’s farm where it would grow up happily.

Another thing that has happened to influence my belief is that I have a neighbor that really likes hunting.   One day he hunted a deer and brought the body home, but he decided to leave it outside his house for everyone to see. He just left it there as if it were some kind of award that he just won. Sadly little kids started to make fun of the body and pretended to ride on it. They laughed at it and felt no problem with there being a dead deer just laying.

Paragraph 1：

I felt sick by what was happening and left because of what I had just witnessed._

Paragraph 2：

It amazes me how we have changed from hunting to survive to hunting for sport._
