2 . Challenges are part of life and something we can all expect to encounter at one point or another during our lifetime. We handle challenges differently;some of us choose to face them head-on, while others flee in uncertainty.     1    The following are simple methods and strategies we can all employ to overcome challenges more effectively.

    2     Nike couldn’t have said it any better with their slogan, "Just do it! "Some challenges require us to do just that. Grab the bull by its horns and have the courage to conquer it, no matter how unsure we might feel. Some challenges are urgent and require immediate attention, leaving us with no option but to go ahead full-steam.

Educate ourselves. The reason why some issues prove challenging for us is that we aren’t familiar with them.     3     The internet, books, forums, etc. , offer platforms where we can research and learn about our challenges to find strategies against them. Knowledge is definitely powerful and essential in conquering anything.

Be persistent. This is what is required to accomplish anything, especially when it comes to overcoming challenges. No matter how difficult our challenges might be, we must be willing to push through and try again and again until we achieve victory over them.     4    

Ask for help. There are times when we can’t go it alone and need others to help us conquer whatever challenges we face.     5     Networking with like-minded individuals who can offer us support, suggestions, and solutions is useful in helping us overcome challenges.

A．Meet them head-on.

B．Adapt a different strategy.

C．It is said that two heads are better than one.

D．If we give up, we allow the challenges to conquer us instead.

E．Therefore, our knowledge and ability to conquer them is limited.

F．Whatever our positions, we all wish to conquer them and move on.

G．Some challenges can be overwhelming, making us question our ability to overcome them.

4 . Selecting gifts for your beloved ones can be one of the most difficult parts. But don’t worry! We can help! Here are some gift ideas to suit all pockets.

Air purifier

Do you have a loved one who suffers from allergies (过敏) or other skin diseases? Why not gift him or her an air cleaner? Research has shown that air purifiers can help reduce allergy reactions, remove asthma (哮喘) causes such as dust by improving air quality in your home. Look for purifiers with more than one filter and, especially, a high efficiency air filter.

Electric toothbrush

One review of 56 studies has found that a powered toothbrush resulted in a 21 per cent reduction of plaque and an 11 per cent reduction in gingivitis (牙龈炎) after three months, compared with a manual toothbrush. It’s also a fun way for children to look after their dental hygiene.

Dark chocolate

Nothing screams a gift quite like chocolate. Good news is that dark chocolate is associated with several health benefits. Small amounts of this sweet treat may lower the risk of heart disease, improve brain function and give your immune system a boost, potentially reducing infection.

Your time

Quality time spent with your nearest and dearest is completely free, but is the most precious gift you could give them. If you’ve been too preoccupied of late, determine to put aside more hours to do fun things together, or if you have time to devote to others outside your immediate circle, consider volunteering with Age UK as a friend to an elderly person.

1. Which of the following is suitable for someone with a dental problem?

A．Air purifier.	B．Electric toothbrush.
C．Dark chocolate.	D．Your time.

2. What do the first three presents have in common?

A．They belong to tech presents.	B．They are non-physical objects.
C．They are intended for the elderly.	D．They help promote healthy living.

3. What is special about the last present?

A．It is priceless.	B．It is worthless.
C．It is physical.	D．It is rare.

5 . A working semiconductor (半导体) has been created from graphene(石墨烯), potentially laying the foundation for a new type of computer with greater speed and efficiency than today’s silicon chips(硅基芯片) allow.

Graphene, a material made from a single layer of carbon atoms, is a good electrical conductor resistant to heat and acids. But a working graphene semiconductor which can be controlled to conduct or separate electricity at will, has evaded scientists. Such semiconductors are key to creating the logic chips that power computers.

The problem has been the lack of what is known as a bandgap. Semiconductors have bands of higher and lower energies and a point—the bandgap—at which excited electrons can jump from one to the other. This effectively allows the flow of current to be switched on and off, so it is either conducting or not conducting, creating the binary system of zeroes and ones used in digital computers.

Now, Walter de Heer at the Georgia Institute of Technology and his colleagues have created graphene with a bandgap and demonstrated a working transistor, an on/off switch that either prevents or allows current to flow through it. De Heer said the electrical properties of a graphene semiconductor were far better than those of silicon chips. “It’s like driving on a rocky road versus driving on a freeway,” he said.

Silicon chips are cheap to make and backed by extensive production facilities, but we are reaching their limits. Moore’s law states the number of transistors in a circuit will double roughly every two years, but the rate of downsizing has slowed recently as engineers reach circuit concentration beyond which electrons can’t be reliably controlled.

“You can use all the technology the whole semiconductor industry is totally comfortable with to scale up this process,” says David Carey at the University of Surrey, UK. But he suspects the world will soon shift to graphene chips, because silicon has such a head start. “Most people working on silicon are bombed daily by new, wonderful materials that are about to replace it and none of it’s ever happened,” he says.

1. What does the underlined word “evaded” probably mean in paragraph 2?

A．Surprised.

B．Attracted.

C．Annoyed.

D．Puzzled.

2. Why is a bandgap crucial?

A．It excites the jump of electrons.	B．It creates the system of zero s and ones.
C．It balances the higher and lower energies.	D．It allows the on and off of the current flow.

3. What advantage might graphene semiconductor have over silicon chips?

A．Superior electrical characteristics.	B．Stronger production support.
C．Lower development cost.	D．Slower downsizing rate.

4. What may be David’s attitude to graphene chips’ application in the near future?

A．Uncaring.

B．Favorable.

C．Doubtful.

D．Disapproving.

6 . A new form of real estate(不动产)is appearing along the beaches of South Africa and on the dry islands off its coast-tiny white beach huts. With good ventilation and a sea view, they are just big enough to fit a family of African penguins. Their unique selling point: a safe and cool place for penguins to breed.

African penguins, unlike their relatives that live in snow and ice, live well in the cold currents of the South Atlantic Ocean. But when they come to land, their thick black coat absorbs the heat, and they desperately look for cover-both for themselves and their fragile eggs.

Historically, the penguins dug burrows in layers of guano-accumulated seabird and bat feces- that lined Africa’s penguin colonies, but in the 19th century, traders started selling guano(鸟粪)as fertilizer, leaving the penguins and their eggs increasingly exposed to predators and the baking sun. This, combined with other threats such as egg poaching, overfishing and climate change, has caused African penguin populations to plummet. In 2019, they were thought to be less than 20,000 breeding pairs, down from an estimated 1.5 to 3 million birds in 1900.For more than a decade, the species has been listed as endangered by the IUCN.

To date, the African Penguin Nest Project has installed more than 1,500 nests across five of South Africa’s penguin colonies, and plans to expand into Namibia next year, the only other country with breeding populations of the species.

“This is still just a drop in the bucket,” says Graham, who anticipates they will need to deploy at least 4,500 more ceramic homes to protect penguins currently nesting in exposed areas. “The goal is that every penguin that needs a nest will get one.”

1. What is the reason for building the beach huts?

A．To beautify the beach.	B．To conduct research.
C．To house the penguins.	D．To balance the ecology.

2. How many factors have affected the penguin populations according to the text?

A．Four.

B．Five.

C．Six.

D．Seven.

3. Which of the following can replace the underlined word “plummet” in Paragraph 4?

A．Innovate.

B．Increase.

C．Swing.

D．Decline.

4. Which column may the text appear in a newspaper?

A．Culture.

B．Environment.

C．Technology.

D．Art.

10 . Although many of us may accept in theory that failure is a necessary component of all learning and growth, in practice,     1    . We may know that we need a growth mindset in order to develop, but failure remains an experience that is often associated with shame.

There are various reasons why we may fear failure.     2    . When we fail at something, our self-image suffers. We may feel worthless, and we may criticize ourselves for our failure. If we fail publicly, our failure will be visible to others. We may fear other people’s judgment. We may fear that our failure will impact or end our career, or else that it will damage our fame.

How, then, can we overcome our fear of failure so that we can truly benefit from what failing has to teach us?

    3    . Reminding yourself that there is no growth without failure — no learning, no development, no new experiences — can help you see what you dislike in a new light. Be open to learning from failure for overall development.

    4    . Try to learn a new skill or hobby — a sport, cooking, dancing, drawing, playing an instrument — and be kind to yourself in the learning process. Mindfully allow yourself to fail, to try again, to fail again but better, and try again, until you get somewhere.

Keep a little diary in which you record what your failures have taught you. Instead of feeling sorry for yourself when you fail, ask yourself: What can I learn from this experience? And remember:     5    .

A．we can easily make the most of it

B．Look at your attitudes about failing

C．we often struggle greatly with failing

D．Build your failure muscle gently in a safe space

E．Fear may prevent you from seeking new experiences

F．While it is hard to fail, it is much worse never to have tried to succeed

G．Perhaps the most common is that our self-worth tends to be tied to success
