2 . The world has spent a long time living with the pandemic. But many people have become lazy about protecting their safety. Are you spending time indoors and unmasked with trusted friends? Or eating in restaurants or making more trips to the grocery store? New types of COVID-19 mean you should try to cut back on exposure. And where you can, double down on basic safety.     1    .     .

Wear masks

The N95 mask is the gold standard. It may cost too much or be hard to find. A cloth mask does a good job of filtering particles that cause infection.     2     — two cloth layers with a filter in the middle. Double masking is the best answer when you find yourself around strangers. The KF94 mask is a good bet.

    3    

If you go to the store two or three times a week, cut back to once a week. If you have been spending 30 to 45 minutes in the grocery store, cut down your time in the store.     4    . If you are waiting in line, be mindful of staying at least six feet apart from the people ahead and behind you. Try using delivery services or curbside pickup.

Spend less time indoors with people who are not from your household. If you must spend time with others, wear your best mask. Be sure any space is well ventilated (通风)(open windows and doors). Keep the visit as short as possible.     5    

The coronavirus vaccine may or may not be the solution. As of now, you are the best answer. Take care. Do not let your guard down!

A．Wash your hands frequently

B．Spend less time with others

C．The best mask has three layers

D．Don’t stay outdoors alone for a long time

E．If the market is crowded, come back later

F．It is still best to minimize your social activities

G．Here are two important ideas about how to stay safe

3 . As you walk around the UK in March, you might notice that some people are wearing a daffodil(水仙花) on their coats. The British wear these yellow flowers to show they support one of this country’s best-known charities: the Marie Curie Cancer Care.

The Marie Curie Cancer Care tries to ensure everyone diagnosed with cancer is cared for in the best possible way. It also helps fund research into possible cures through other organizations. Founded in 1948, it has been continuing with its goal ever since.

The charity was named after Marie Curie, a renowned scientist. She experimented with newly-discovered elements to create the theory of radioactivity. Unfortunately, over-exposure to the radioactive elements made her develop a disease and die in 1934. Marie Curie won the Nobel Prize in two different fields. Because of her pioneering work which led to chemotherapy (化学疗法), the charity shared the name of Marie Curie.

The daffodil is one of the first plants to flower during spring in the UK, which marks the return of flowering plants to the ecosystem after winter. Because of this, the charity uses the daffodil as a metaphor for bringing life to other people through charitable giving.

Everyone you see wearing a daffodil has donated money to the charity, but each daffodil is worth only what you want to pay for it. The charity does ask that you stick to a minimum amount of £1.

The charity encourages people to start wearing their daffodils at the start of March, when the “Great Daffodil Appeal” kicks off. But that doesn’t mean you can only wear them in March. People are sometimes seen walking around with daffodils on their clothes all year round.

5 . Sulphur-crested cockatoos (葵花凤头鹦鹉) are common in western Australia, where they normally live in wooded areas. But as forests have been cut down, cockatoos have gotten used to living near people. Scientists report that people in Sydney, Australia are in a battle with these birds.

Last year, scientists at the Max Planck Institute reported that the cockatoos had learned how to open the covers of trash bins. That’s not an easy job. The cockatoos must lift the heavy cover with their beaks (喙) and then walk along, pushing the cover up until it falls over.

When scientists first began studying the cockatoos in 2018, only three areas near Sydney had cover-opening cockatoos. A year and a half later, cockatoos in 44 different areas knew the trick. This time the scientists weren’t just studying cockatoos. They were also studying humans.

The scientists spent weeks studying more than 3,200 trash bins in four different areas of Sydney. They wanted to see how many bins were protected and what methods were used.

In one area, over half the bins were protected. The most common way of protecting the bins was to put a brick or some other heavy objects on the cover. Some people put things like rubber snakes on the top of their bins. The scientists discovered that the humans were teaching each other tricks, too. In most neighborhoods, many people used the same cockatoo-stopping methods as their neighbors.

The researchers say it’s like a race between humans and cockatoos to learn new ways of doing things. Now many cockatoos have learned how to push heavy items off the bins. As a result, humans have figured out ways to attach the items to the top of their bins. The scientists describe the situation as a “human-wildlife conflict”. They expect these conflicts will become more common as humans take over more areas that used to be wild.

3. What did the researchers find about cockatoos in their research?

A．They wanted their habitat back.

B．They intended to make humans angry.

C．They could adopt new ways to open bins.

D．They disliked looking for food themselves.

4. What is the best title for the text?

A．A battle over trash bins between cockatoos and humans

B．A human-wildlife conflict all over Australia

C．A problem caused by cockatoos to humans

6 . 阅读下面短文，在空白处填入1个适当的单词或括号内单词的正确形式。

Ever wonder    1    it would feel like to hide away in a dark cave without being connected to the outside world for 40 days? Fifteen people in France just did that. The group    2    (live) in a cave as part of the Deep Time project. The project was conducted by scientists from the Human Adaptation Institute, who wanted to see how they would react to and cope with being    3    (total) disconnected from the modern world. Since the volunteers    4    (cut) off from the outside world, they had to rely    5    their body clock to know when    6     (wake) up, go to sleep and eat. As expected, those in the cave lost their sense of time. “Time seemed to pass more slowly in the underground cave, where there were neither clocks    7    sunlight,” said Deep Time’s director Christian Clot.

The majority of the volunteers said they enjoyed the experience of total isolation. Two-thirds expressed a desire to remain underground a while    8    (long) in order to finish projects they had started. “The experience tested humans’ ability to adjust    9    (they) to the sudden huge changes in living conditions and environments,” said Clot. “We hope to better understand how our brains are capable of    10    (find) new solutions, whatever the situation.”

8 . Four ways to be admired

Gaining admiration requires honesty, hard work, perseverance and some other qualities.    1    

Lead, don’t follow.

People who are admired are unafraid to do something new or different.    2    You can be a leader even among those who have greater official authority than you by convincing others to follow a certain course or act in a certain way. Leadership requires more than speaking and acting in an inspirational and influential way. You must also be willing to take responsibility when something needs doing.

    3    

It means you will stand by the things you believe. Admirable individuals try to keep their personal integrity (诚信) by staying true to who they are even when it is unpopular or questioned. However, standing by your principles (原则) and acting with integrity doesn’t mean that you are unwilling to accept or consider other ideas.

Take a positive attitude.

A positive attitude doesn’t mean pretending that everything is great all the time. That is unrealistic.    4    Try to be positive about some negative situations, and maybe things will get better.

Work hard.

Whether you’re working for minimum wage or managing a large company, you should always take pride in your work. Doing so will show that you are capable of doing your part. Go above and beyond in your workplace by giving your all on the job. If you make pizzas, make the best pizza you can every time.    5    Take pride in your work and doing it will be a pleasure, not a hard job. Keep your office or workspace clean and well-organized.

A．Stick to your principles.

B．Show personal integrity.

C．If you clean the floors, make it perfectly.

D．No matter who you are, earning admiration requires many skills.

E．Being a leader doesn’t necessarily mean you are in a higher position.

F．It is important to push people in the workplace to make them feel relaxed.

G．Instead, recognize when things are bad but look for the good in every situation.
