During my lifetime, I’ve learnt something important: it’s good to learn new skills outside of your comfort zone. About seven years ago, I started learning how to paint as a ______. I was pretty terrible. Everything looked ________, and my colors were totally off. My friends and colleagues suggested that I stop ________ my time on something I wasn’t good at. “________ on your day job,” they said.

I kept at it — practicing, taking classes, finding the right ______ who could guide and challenge me. I am now ________ “good”. Today, the same friends say I was born with this _______.

The same thing __________ when I started piano and singing lessons a couple of years ago. Comments shifted from, “Stop wasting your time and focus on what you know,” to “You’ve got a musical gene.”

These _______ originate from long-held beliefs that growth is usually not possible for adults. Even when there is evidence of learning, it can be _______ to inborn talent. Most scientific studies on adulthood focus on cognitive (认知) decline, rather than _______, suggesting that even scientists may think that development is limited in adulthood.

A few recent studies suggest that ________ new skills, such as photography, for even three months may enhance the functioning of the brain in adults.

I would take these studies one step further to argue that a(n) ________ cause of cognitive decline is the fact that adults learn fewer new skills _______ to children. If we can _______ how to learn well as adults, then perhaps we can ________ cognitive decline.

Adults are often _______ to go outside of their comfort zones. We fear looking _________ for making mistakes; we fear failure could cost us our jobs. Perhaps a reason why we suffer from cognitive decline is that we do not engage in learning new skills for many years.

To better communicate with my German friends, I am starting to learn German. I’m ________ at the“listening and babbling (咿呀学语)” phase. Sure, some may laugh at an adult babbling, but I hope one day I can __________ German fluently, and inspire many other adults to learn like a baby.

高三英语完形填空中等难度题查看答案及解析

Nowadays, more people lose their jobs and the prices of goods and services steadily increase. 1.. But where do I start? Everything I’m paying for is necessity. There’s nothing I can cut down on.

But if you take a careful and objective look at your bills and all the “stuff” you’re paying for, you actually do not need a good majority of them. I’ve put together 5 tips that you can follow right now to reduce your costs.

1.Cut Back on Eating out.

Maybe you didn’t notice eating out is one of the things at your budget and you can save so much money just by reducing the number of times you eat out. 2.It’s so much cheaper preparing food at home and healthier too. This does not mean that you should never eat out. You can choose special days to eat out like birthdays or anniversaries.

2.Reduce Your Electricity Consumption

3.This will help reduce your electricity consumption. With CFLs(节能灯)you save so much on power. Also unplug appliances(家用电器)that you’re not using.

3.Cut Back on Magazine or Print Subscription(订阅费)

Magazines are great but sometimes they come with articles that you don’t really care about so you don’t bother reading them. 4.Review　 your　 magazine　 or　 print　 subscriptions　 to determine which ones to unsubscribe from. You can also draw out a list of topics or categories you like reading about and search for free online alternatives where you can read about the topic of your choice.

4.Cancel Your Gym Membership or Go for a Pay-Per-Use Plan.

Exercise is important to stay healthy. In fact, you save more money when you stay physically fit than if you are in poor health. But there are more affordable ways to keep fit, if you exercise for health’s sake and no as a body builder or something.

Exercise at home or jog around your neighborhood. If you can’t work out without an exercise trainer, try searching for exercise routines on You Tube. If you want to u se gym equipment, then you can convert your gym membership style to pay-per-use. 5.

Of course, you don’t need to practice all of these at once, but if you are really willing to cut down on those costs, then one of these will surely come in handy.

A.Start by turning off the lights you’re not using.

B.They’re so simple but the results are impressive

C.As an alternative, make more home-cooked meals

D.It’s time for you to take action and do something about your bills

E.That way you pay only when you come to the gym to use the equipment

F.Invest in gym equipment to cut down recurrent costs of gym membership

G.These days most of the information or news is available on the Internet for free.

For underwater photographer Brian Skerry, there are good days. The sun shines, the water's clear. But most days aren't like that. The whales don't show up, or there are particles (颗粒)in the water, or wind brings the waves, or the sun dips behind a cloud at the worst moment.

A National Geographic photography fellow and the 2017, Rolex National Geographic Explorer of the Year, Skerry free dives — which means no scuba tanks, no equipment except his fins, mask, and camera. Over the past two years he's spent nine weeks off the eastern Caribbean island of Dominica in a 30-Foot boat running after sperm whales around their warm-water habitat.

Sperm whales are intelligent, and mad, escaping to ocean depths when pursued. Still, their ranks have been thinned by whaling, overfishing, and other contact with humans, to the point that the world's conservationists assess them as either vulnerable or endangered. Skerry wants his photos to inform the scientific research and education efforts that will bring whales more attention and potentially some relief. “I feel a sense of responsibility and urgency to make people care about the marine giants,” he says. “I want to give them, for lack of a better word, some humanity.”

Scientists know sperm whales as the ocean's largest toothed animals that kills other animals. They have the biggest brains of any known animal, can weigh up to 45 tons, and have been observed displaying humanlike qualities, such as curiosity and playfulness. But despite their size and their expressiveness, sperm whales remain one of the ocean's biggest mysteries. Do they share complex ideas?

1.What is "free dives"?

A.Diving without charge. B.Diving without sponsors.

C.Diving with little equipment. D.Diving with few regulations.

2.What does the underlined word "vulnerable" probably mean?

A.Easily attacked. B.Strongly built.

C.Desperately driven. D.Distantly removed.

3.What can we learn about the sperm whales from the text?

A.Sperm whales are the largest fish in the sea.

B.Sperm whales are as clever as the human being.

C.Sperm whales enjoy being photographed by photographers.

D.Sperm whales' population has declined due to illegal fishing.

4.Where is the text probably taken from?

A.Technology magazine. B.Tourism advertisement.

C.National geography. D.Entertainment report.

Most people agree that honesty is a good thing. But does Mother Nature agree? Animals can't talk, but can they lie in other ways? Can they lie with their bodies and behavior? Animal experts may not call it lying, but they do agree that many animals, from birds to chimpanzees, behave dishonestly to fool other animals. Why? Dishonesty often helps them survive.

Many kinds of birds are very successful at fooling other animals. For example, a bird called the plover sometimes pretends to be hurt in order to protect its young. When a predator（猎食动物）gets close to its nest, the plover leads the predator away from the nest. How? It pretends to have a broken wing. The predator follows the "hurt" adult, leaving the baby birds safe in the nest.

Another kind of bird, the scrub jay, buries its food so it always has something to eat. Scrub jays are also thieves. They watch where others bury their food and steal it. But clever scrub jays seem to know when a thief is watching them. So they go back later, unbury the food, and bury it again somewhere else.

Birds called cuckoos have found a way to have babies without doing much work. How? They don't make nests. Instead, they get into other birds' nests secretly. Then they lay their eggs and fly away. When the baby birds come out, their adoptive parents feed them.

Chimpanzees, or chimps, can also be sneaky. After a fight, the losing chimp will give its hand to the other. When the winning chimp puts out its hand, too, the chimps are friendly again. But an animal expert once saw a losing chimp take the winner's hand and start fighting again.

Chimps are sneaky in other ways, too. When chimps find food that they love, such as bananas, it is natural for them to cry out. Then other chimps come running. But some clever chimps learn to cry very softly when they find food. That way, other chimps don't hear them, and they don't need to share their food.

As is mentioned above, animals behave dishonestly for survival. Is it OK to lie for us human?

1.The writer uses the three questions at the beginning of the passage to _________.

A. ask the readers to answer the questions

B. draw the readers’ attention to the topic

C. seek answers to the questions

B. A scrub jay dug out its buried food and reburied it somewhere else.

C. The adoptive parents feed their baby birds of cuckoos.

D. A losing chimp starts fighting again after taking the winner’s hand.

3.The underlined word “sneaky” in paragraph 5 most probably means______.

A. selfish　　　　 B. friendly

C. entertaining　 D. dishonest

4.What is the common reaction of most chimps when they find their favorite food?

A. They let out a loud cry

B. They cry in a very low voice

C. They hide their food immediately

D. They share their food with other chimps.
