How to Prepare for Guests

    Guests are people whom we welcome sincerely and we should make sure they feel comfortable like they are in their home. Sometimes we get enough time to make preparations for guests, but sometimes we don't. This article will be beneficial for both these kinds of people. {#blank#}1{#/blank#}

    Get a bedroom for your guests. It doesn't have to be complicated. Change bed covers, clean the bathroom and you can even add a nice scented(芬芳的) candle to spice things up. These are simple things you can do even if you are a very busy person. {#blank#}2{#/blank#}

    Know what your guests' favorite foods are so that you can make for them and serve. Don't forget to note down if they are allergic to any certain kind of food to save the embarrassment(难堪). If you are among one of those people who can hardly manage the time to cook for your guests then take them to the restaurants so that they can taste new foods or enjoy their favorite ones.

    Plan activities to have a good time with your guests. {#blank#}3{#/blank#} If they come over the weekends then plan for some indoor activities to have fun. It's also a good way to remove your tiredness from your boring life.

    {#blank#}4{#/blank#} It can happen that you may not be able to be with your guests for a certain amount of time while they are staying in your home. In that case you must declare it to them and may have someone else to accompany them while you are absent.

    When your guests say goodbye, give them something as a token(信物) of love to remember the days they stayed with you. {#blank#}5{#/blank#}

A. Declare your absence.

B. Allow them to come and go as they please.

C. Just bear in mind everything fresh and clean will do fine.

D. If they come during the vacation then you can plan for outdoor activities.

E. Here are some ways to help you to put away things well in a short amount of time.

F. Make your guests feel even more welcome by including them in activities such as outings, or movies.

G. It can be just a photo in a beautiful frame that will remind them of beautiful moments that they spent with you.

    Movies have documented America for more than one hundred years. Since Thomas Edison introduced the movie camera in 1893  amateur and professional movie-makers have used moving pictures to tell stories and explain the work of business and government. {#blank#}1{#/blank#} By preserving these movies, we will save a century of history.

    Unfortunately, movies are not made to last. {#blank#}2{#/blank#} Already the losses are high. Only 20% of US feature films from the 1910s to 1920s survive. Of the American features produced before 1950, about half exist. For independently produced works, we have no way of knowing how much has been lost.

    For many libraries and museums, the hardest step in preserving movie collections is getting started. The Movie Preservation Guide is designed for these organizations. {#blank#}3{#/blank#} These institutions have collections of moving pictures but lack information about how to take care of them. The guide contains basic facts for "beginners"—professionals trained in history but unschooled in this technical area.

    The guide grew from user workshops at Duke University. At the sessions, beginners talked with technical experts about what they needed to know to preserve and make available their movie collections. {#blank#}4{#/blank#}

    Following the advice, the guide describes methods for handling and storing moving pictures that are practical for research institutions with limited resources. {#blank#}5{#/blank#} The guide has been translated into Chinese, Japanese and Korean.

A. "Keep it simple!" was the advice of the discussions.

B. They'll be damaged within years if not properly stored.

C. These organizations are the first to save American movies.

D. It is organized in chapters and includes case studies and charts.

E. It introduces movie preservation to nonprofit and public institutions.

F. They show how generations of Americans have lived, worked and dreamed.

G. They store the original movies and new ones under cool-and-dry conditions.

    To someone stuck in a traffic jam, the ability to fly right over other cars seems like a dream. {#blank#}1{#/blank#} That may be changing. Nearly a dozen companies around the globe are competing to be the first to develop a flying car. One of the ideas being developed is a car with wings that unfold for flight. But, most aren't cars at all. They are more like helicopters and are operated by a battery-powered motor.

    {#blank#}2{#/blank#} Companies have to convince the government that the flying cars are safe. They will also need longer-lasting batteries. And, cities will have to figure out how to handle thousands of flying cars in the sky.

    Still, some companies are moving forward. {#blank#}3{#/blank#} Especially as cities grow more crowded and people spend more time stuck in traffic. These taxis would deliver passengers to the rooftops of office buildings during rush hours.

    "In as little as 10 years, products could be on the market that revolutionize urban travel for millions of people," said Zach Lovering. He is the leader of a project to develop a self-flying taxi for Airbus, a European company that makes airplanes. {#blank#}4{#/blank#} Although Uber doesn't have any plans to develop a flying car itself, the company is advising several companies that are developing them.

    {#blank#}5{#/blank#} Designers think that if enough people want to buy them, prices can be kept affordable.

A. Some flying cars are designed for human pilots.

B. It's still unclear how much flying cars will cost.

C. They see a need for "air taxis" and personally owned flying cars.

D. Companies will also have to get permission from the government.

E. The Uber ride-share company sees air taxis as the future of on-call transportation.

F. Inventors and business people tried to make flying cars, but have never been able to.

G. There are many challenges that could keep flying cars from becoming part of everyday life.

    Why do you run? Different people have different reasons. Whatever your reason, there's one thing we can be sure of: Running is much better injury-free. In his book, Dr. Jordan Metzl's Running Strong, Metzl has the perfect suggestions for enjoying your running without losing your well-being. Here are five must-follow rules for injury-free running:

    ⒈Train for your level of fitness and your goals.

    {#blank#}1{#/blank#} If you run for fitness and your goal is 30 minutes a day, that's cool. But if you are just starting out, you need to get there slowly.

    ⒉Wear the right shoes for your feet.

    You will hear lots of opinions about whether running shoes really help prevent injury and whether you should even wear them. {#blank#}2{#/blank#} And some of you may need a little added assistance from inserts (鞋垫).

    ⒊{#blank#}3{#/blank#}.

    Be honest about how much sleep you need and stick to it. The cool runner is the one who wins the race. Sleep will get you there.

    ⒋Fuel (给提供能量) your body right for running and recovery.

    {#blank#}4{#/blank#} And after workout or race, you need to deliver nutrients (营养物)to all the body rebuilders in your muscles, so they can do their job and get you back into perfect shape for your run tomorrow.

    ⒌Pay attention to pain.

    When pain changes the way you run, stop running. {#blank#}5{#/blank#} And use dynamic rest (动态休息)to stay in shape until you are back on your running feet.

A. Try to find out what's going on and treat it.

B. Get seven to eight hours of sleep every night.

C. Running should be seen as fun rather than pain.

D. Don't run more miles than your body can deal with.

E. A good pre-run meal plan is one that keeps you stepping strong.

F. It is because of the health benefits, including lowering your risk for disease.

G. The right running shoes can help correct foot-movement problems that lead to injury.

Critical thinking is the process of carefully and systematically analyzing problems to find ways to solve them. It involves identifying several possible solutions and then logically evaluating each one, comparing them to one another, and then selecting the one that you conclude is the most promising

{#blank#}1{#/blank#}Employers prefer job candidates who can demonstrate a history of using critical thinking skills. They want to have employees who can solve problems quickly.{#blank#}2{#/blank#}

You may think there isn't enough time to take a slow and measured approach to problem solving. After all, time is limited, and quick and easy answers are appealing.{#blank#}3{#/blank#}

Critical thinking is one of several life skills you should try to develop while still in school.{#blank#}4{#/blank#}Your assignments will require you to generate hypotheses (猜想) and then test them before coming to conclusions. Students taking art classes also use critical thinking. To complete projects, you will have to select media and techniques that will best allow you to achieve your artistic vision

Graduates aren't out of luck. Practice your critical thinking while performing everyday activities.{#blank#}5{#/blank#}When deciding where to have dinner, weigh your alternatives regarding the type of food, healthfulness, and cost. If making a purchase, do your research and read reviews of different brands.

A. Sign up for science classes, for example.

B. Choose a lesson that benefits your critical thinking.

C. The ability to think critically is a valuable soft skill in the job market.

D. But more importantly, they want ones who can solve them effectively.

E. We all need some critical thinking skills living in this challenging world.

F. For example, before going out, learn about each means of transportation.

G. However, rushing to make a decision is less productive than using critical thinking.

As the world struggles to deal with the climate crisis, some companies are working to remove polluting carbon dioxide from the air. {#blank#}1{#/blank#} But two US companies have recently made important progress. 

Scientists say large amounts of CO₂ must be removed from the CO₂ atmosphere and stored. {#blank#}2{#/blank#} But there's so much CO₂ in the atmosphere that just planting trees and protecting forests won't solve the problem. And, when plants and trees die, the carbon they've stored gets released again. 

That means humans need to come up with ways of removing carbon from the air and storing it. This is called Direct Air Capture (DAC). The science of removing carbon from the air is challenging, and it's still pretty new. {#blank#}3{#/blank#}So one puzzle for these companies is how to remove carbon without creating more pollution. 

A company called Heirloom has just opened the first DAC plant in the United States. The company heats up the limestone to separate out the CO₂, which is concrete. The process is extremely expensive. {#blank#}4{#/blank#}That's a tiny amount compared to how much carbon needs to be removed from the atmosphere, but the company says it hopes to remove a billion tons per year by 2035. 

 {#blank#}5{#/blank#} Some people worry that it will take too long for DAC technology to become powerful enough to make a difference. Others worry that focusing on removing carbon could take attention away from more important climate actions, like switching from fossil fuels to renewable energy. But experts say the decision isn't to do one or the other. The world needs to end fossil fuel use and pull carbon out of the air. 

A. Plants and trees do this naturally.
B. That's a huge and challenging goal.
C. Not everyone is excited about carbon removal.
D. Graphyte is another US company working on DAC.
E. The new plant can remove 1,000 tons of CO2 a year.
F. Most DAC processes require a large amount of energy.
G. As a matter of fact, CO₂ is just a small part of the gases that make up air.
