How to Design a Logo

A great logo is more than images and words,and a good logo tells a story about your company-who you are,what you do and what you stand for.1.And it is why it’s important that you take the time to do it right. Fortunately, you don’t have to do it alone.The steps below will help you design a good logo.

Determine the primary function of your logo.

Being clear on why you need a logo can guide your design.Having a strong logo can help consumers recognize your brand more readily. Consumers shop with their eyes and logos can be easier to remember than names,products and services2.

3.

It’s important to be clear on who your potential customers are and design the look of your logo to appeal to those who will be using your services.A logo for a flower shop could include a unusual character style and a bright color.

Decide whether to include your company’s name into the logo.

Of course,you want to build name recognition for your business,but making the name part of your logo design may not always be a good idea.Include the name if it is reasonably distinctive but not yet a household word.Do not include the name if it is too long,and doesn’t translate well globally or lacks personality.

Be inspired by but don’t copy successful logos.

While it might be easy to create something that looks like your favorite company’s logo,it will leave an impression on consumers that you’re lazy and uninspired. Look at logos of other companies.4.These examples give you ideas of what to do and what to avoid.

Keep it simple.

While it may be easy to try to give a lot of messages with your design,trying to do too much will ruin your logo.5.If there are too many messages in your logo, it will be difficult for the customer to process.

A.Think about your target market.

B.That’s a lot to ask of one piece of art.

C.Ask yourself what you like and don’t like about them.

D.Avoid too many colors, different characters and images.

E.A good logo that conveys your honesty can help put customers at ease.

F.Over time, a customer comes to associate your logo with your company.

G.Show your logo to those connected to you and listen to what they have to say.

    We already know that a lack of sleep will actually prevent your brain from being able to make new memories. You end up feeling as though you’re amnesiac.

A lack of sleep will lead to an increased development of a protein in the brain connected with Alzheimer’s disease because it is during deep sleep at night that a system within the brain starts to wash away this protein. So if you’re not getting enough sleep each and every night, more of that Alzheimer’s-related protein will build up. The more protein that builds up, the greater your risk of developing Alzheimer will be in later life.

What are the effects of the lack of sleep on the body? We know that a lack of sleep impacts your immune system(免疫系统).After just one night of four to five hours of sleep, there is a 70%reduction in immune cells called natural killer cells. And that’s the reason that short sleep predicts your risk for developing many forms of cancer.

In fact, the link between a lack of sleep and cancer is now so strong that recently the World Health Organization decided to classify any form of nighttime shift work as a probable cause of cancer. It is during deep sleep at night that your heart rate drops, your blood pressure goes down. If you’re not getting enough sleep, your blood pressure rises. If you’re getting six hours of sleep or less, you’ll have a 200%increased risk of having a deadly heart attack or stroke in your lifetime.

There is a global experiment that is performed on 1.6 billion people twice a year and it’s called daylight savings time. And we know that in the spring, when we lose one hour of sleep, we see a 24%increase in heart attacks the following day.

Another question, perhaps, is what is the recycle rate of a human being? How long can we actually last without sleep before we start to see worsening in your brain function? And the answer seems to be about 16 hours of wakefulness. Once you get past 16 hours of being awake, that’s when we start to see mental and physical damages in the body. We know that after you’ve been awake for 19 or 20 hours, your mental capacity(心智能力)is so damaged that you would be as slow as someone who was drunk. So if you were to ask me what is the recycle rate of a human being, it does seem to be about 16 hours and we need about eight hours of sleep to repair the damage of wakefulness.

1.The underlined word “amnesiac” in Paragraph 1 probably means

A.sleepy B.tolerant C.relieved D.forgetful

2.According to the article, we can infer that_

A.the more you sleep, the more protein there will be

B.you’re more likely to suffer heart attacks in the spring

C.deep sleep at night protects you from a harmful protein

D.you’ll develop many forms of cancer due to short sleep

3.When you’re awake over 16 hours,        .

A.your brain won’t function in a proper way B.your brain needs at least 8 hours to recover

C.you must have drunk large amounts of wine D.you walk as slowly as the physically disabled

4.What is the best title for the passage?

A.Sleeping sickness kills B.Enough sleep counts

C.Less sleep causes cancer D.Sleep is necessary for man

    An experiment which saw salad seeds sent into space has given hope for the future of growing food on another planet, according to a recently-published study.

The findings have appeared after two kilograms of seeds spent six months on board the International Space Station(ISS)with British European Space Agency(ESA)astronaut, Tim Peake, as part of his Principia mission.

There, the seeds could have absorbed up to 100 times more radiation(辐射)than on Earth while being influenced by the violent shaking from the stresses of space travel.

When the seeds returned to Earth in 2016,600,000 children from schools across Britain took part in an experiment, supported by the UK Space Agency, to plant them and monitor their growth, comparing it to that of seeds that had remained on Earth.

The results showed that, while the space seeds grew more slowly and were more sensitive to ageing, they were still able to survive.

Peake said, “When humans travel to Mars, they will need to find ways to feed themselves, and this research helps us understand some of the biology of seed storage and germination(发芽) which will be important for future space missions.”

The Royal Horticultural Society(RHS)tasked 8,600 schools and groups across Britain to take part in the controlled study, recording their results as a scientist would.

It was part of a project called Rocket Science, led by the RHS Campaign for School Gardening, in partnership with the UK Space Agency.

RHS manager Alana Cama said, “The Rocket Science experiment opened a window into space biology and allowed young people to be at the forefront of creative research.”

“This research project did more than just inspire; it furthered our understanding of the challenges around growing plants in unusual environments and the possibility of growing food on long-term space missions in the future. Inspiring a new generation of botanists and biologists will remain our goal to enrich everyone’s lives through plants.”

1.The findings of the experiment indicate that      

A.salad seeds sent into space turned out a failure

B.astronauts successfully grew salad seeds on Mars

C.the future of growing plants in space looks bright

D.the radiation makes it impossible for plants to survive

2.Unlike those on Earth, the seeds sent into space       

A.can grow 100 times larger in size B.provide enough food for astronauts

C.stop growing when returning to Earth D.are more likely to show signs of ageing

3.Which word can be filled in the blank to complete the research steps?

A.update B.observe C.protect D.improve

4.What can we learn from what Alana Cama said?

A.Growing plants in unusual environments is no longer a challenging task.

B.A new generation of botanists and biologists takes the lead in the research.

C.The project inspires the interests of the young generation in creative fields.

D.The exploration of growing food in space is the central mission in the future.

    I was diagnosed(诊断)with cancer last June. Finding out that I had breast cancer felt like I’d been locked up in a prison cell, but I later found something unexpected: freedom.

Tests and procedures followed. Once the daily treatments started, I was tired out. The tiredness that came with cancer was not like any kind of tiredness I’d known before.

Then the magic happened.

I started to realize that this life change had brought an unexpected gift. The usual pressures of life gave way to a different kind of stress, but it came with self-discovery. I do what I can and don’t care about the rest. With the disease, decisions come more easily, and things that I’d previously weighted more heavily no longer matter as much. I don’t need a perfect home. What does matter now is having family and friends and a husband who can shoulder this new responsibility with me.

The doctor says my situation is very good and there’s a 91 percent chance that I’ll still be alive in 10 years. I look forward to simple things like my garden this spring, and going back to work when I’m healthy again. I’m also imagining the joy of getting my quiet and modest life back. It’s inspiring and there are lots of people there with me. And the professionals are really good at what they do.

I used to wonder how it would feel to be told I had cancer. Sure, my first reaction was fear, panic, sorrow, and anger. Then I found my strength. The fear is still there, but to my amazement, I am handling it. “You got this,” people say encouragingly.

1.What does the underlined sentence in Paragraph 1 mean?

3.What is the author’s attitude towards her future life?

A.Positive. B.Hopeless. C.Doubtful. D.Concerned.

4.What is the main purpose of this article?

A.To help people learn to let go of stress in life. B.To remind people to take care of their bodies.

C.To encourage people to shoulder responsibilities. D.To inspire people to learn from her experiences.
