Directions Read．the following passage．Fill．in the numbered, blanks by using the information from the passage．
Write NO MORE THAN THREE WORDS for each answer．
Learning to improve your focus throughout the day can be a little difficult, only because we are talking about 18 to 24 hours, depending on the number of hours you sleep．However, if we break down your day into manageable time frames, it would make it much easier to learn to improve your focus．
Focus, or concentration, is a skill that can be taught, so there are some exercises you can do to improve your focus．
Start with easy exercises like staring at a picture on the wall for a few minutes without moving or talking to anyone．Once you learn how to block out your surroundings, your focus will improve．
Other mind exercises you can do are internalizing．This is when you picture yourself in a desired situation, and then you work around your picture．Actors do this a lot to block out laughter, noise, or other distractions．An example of this would be to imagine you in a potentially stressful situation, like a singer in a concert．Try to play out the scene in your mind what you would do if different scenarios were to happen．This can actually be a lot of fun．and you learn how to improve your focus by concentrating on one thing only．
If this sounds a little strange to you, you could try another strategy．Why not make lists? Make a list for the things you need to accomplish for the morning, another for the afternoon．and finally, another list for the evening．Study your lists carefully and see where you can move things around．
For instance, if you have a dinner to arrange that evening, don't bunch up everything in the afternoon, right before the guests arrive．Divide your chores and errands between morning and afternoon, and give yourself an hour or two to relax before the guests arrive．Planning helps you focus．It will also not stress you out．
Another way to improve your focus is to take breaks．If children have rest and lunch as their breaks, adults should also allow themselves the privilege of stopping for a drink or a 30 minute sitcom on TV．Of course, if you are working in an office, you are allowed coffee breaks．Use this time wisely．Don't spend it with your co-workers beside the coffee machine talking about problems in the office．Doing this would actually stress you and get you to lose focus on the things that need to be done．Your breaks should be as quiet as possible．Read a book．take a walk．or visit a daycare．Go and do anything that will give your brain a rest．
The reason why we lose focus so easily is because we have too much on our minds．Of course, it could also be because you are bored with nothing to do all day．A good balance between a too relaxed brain and an overly active brain is a desirable situation to be in．Find your capacity to work, and try not to veer away too far from it on a daily basis．Improving your focus also means knowing what you can do and being confident about doing it well．

Conclusion Keeping between extremely relaxed brain and too active brain．
Last October ,while tending her garden in Mora ,Sweden ,Lena Pahlsson pulled out a handful of small 56 (carrot) and was about to throw them away .But something made her look closer ,and she noticed a 57 (shine) object .Yes ,there beneath the leafy top of one tiny carrot was her long-lost wedding ring.
Pahlsson screamed 58 loudly that her daughter came running from the house ."she thought I had hurt 59 (I),"says Pahlsson Sixteen years 60 (early),Pahlsson had removed the diamond ring 61 (cook) a meal. When she
wanted to put the ring back on later, it was gone. She
supected that one of her three daughters-then ten. eight, and six- had picked it up, but the girls said they hadn't. Pahlsson and her husband 62 (seareh) the kitchen, checking every corner. but turned up nothing. "I gave up hope of finding my ring again," she says. She never replaced it.
Pahlsson and her husband now think the ring probably got 63 (sweep) into a pile of kitchen rubbish and was spread over the garden, 64 it remained until the carrot's leafy top accidentally sprouted (生长) through it. For Pahlsson, its return was 65 wonder.
Population Change
Why is the world's population growing? The answer is not what you might think. The reason for the explosion is not that people have been reproducing like rabbits, but that people have stopped dropping dead like flies. In 1900, people died at the average age of 30.By 2000 the average age was 65.But while increasing health was a typical feature of the 20 thcentury, declining birth rate could be a defining one of the 21 st.
Statistics show that the average number of births per woman has fallen from 4.9 in the early 1960s to 2.5 nowadays. Furthermore, around 50% of the world's population live in regions where the figure is now below the replacement level(i.e.2.1 births per woman)and almost all developed nations are experiencing sub-replacement birth rate. You might think that developing nations would make up the loss(especially since80% of the world's people now live in such nations), but you'd be wrong. Declining birth rate is a major problem in many developing regions too, which might cause catastrophic global shortages of work force within a few decades.
A great decline in young work force is likely to occur in China, for instance. What does it imply? First, China needs to undergo rapid economic development before a population decline hits the country. Second, if other factors such as technology remain constant, economic growth and material expectations will fall well below recent standards and this could invite trouble.
Russia is another country with population problems that could break its economic promise. Since 1992 the number of people dying has been bigger than that of those being born by a massive 50%,Indeed official figures suggest the country has shrunk by 5% since 1993 and people in Russia live a shorter life now than those in 1961.Why is this occurring? Nobody is quite sure, but poor diet an above all long-time alcoholism have much to do with it. If current trends don't bend. Russia's population will be about the size of Yemen's by the year 2050.
In the north of India, the population is booming due to high birth rates, but in the south, where most economic development is taking place, birth rate is falling rapidly. In a further twist, birth rate is highest in poorly educated rural areas and lowest in highly educated urban areas. In total, 25% of India's working-age population has no education. In 2030, a sixth of the country's potential work force could be totally uneducated.
One solution is obviously to import foreign workers via immigration. As for the USA, it is almost unique among developed nations in having a population that is expected to grow by 20% from 2010-2030. Moreover, the USA has a track record of successfully accepting immigrants. As a result it's likely to see a rise in the size of its working-age population and to witness strong economic growth over the longer term.
If you feel stressed by responsibilities at work, you should take a step back and identify (识别)those of 41 (great)and less importance. Then, handle the most important tasks first so you'll feel a real sense of 42(achieve). Leaving the less important things until tomorrow 43(be) often acceptable.
Most of us are more focused 44 our tasks in the morning than we are later in the day. So, get an early start and try to be as productive 45possible before lunch. This will give you the confidence you need to get you through the afternoon and go home feeling accomplished.
Recent 46 (study) show that we are far more productive at work if we take short breaks 47 (regular). Give your body and brain a rest by stepping outside for 48 while, exercising, or dong something you enjoy.
If you find something you love doing outside of the office, you'll be less likely 49 (bring) your work home. It could be anything-gardening, cooking, music, sports-but whatever it is, 50(make) sure it's a relief from daily stress rather than another thing to worry about.

Secret codes (密码)keep messages private。Banks, companies, and government agencies use secret codes in doing business, especially when information is sent by computer.
People have used secret codes for thousands of years. 36 Code breaking never lags(落后) far behind code making. The science of creating and reading coded messages is called cryptography.
There are three main types of cryptography. 37 For example, the first letters of "My elephant eats too many eels" Spell out the hidden message "Meet me."
38 You might represent each letter with a number, For example, Let's number the letters of the alphabet, in order, from 1 to 26. If we substitute a number for each letter, the message "Meet me" would read "13 5 20 13 5."
A code uses symbols to replace words, phrases, or sentences. To read the message of a real code, you must have a code book. 39 For example "bridge" might stand for "meet" and "out" might stand for "me." The message "bridge out" would actually mean "Meet me." 40 However, it is also hard to keep a code book secret for long. So codes must be changed frequently.
| A． |
It is very hard to break a code without the code book. |
| B． |
In any language, some letters are used more than others. |
| C． |
Only people who know the keyword can read the message. |
| D． |
As long as there have been codes, people have tried to break them. |
| E． |
You can hide a message by having the first letters of each word spell it out. |
| F． |
With a code book, you might write down words that would stand for other words. |
| G． |
Another way to hide a message is to use symbols to stand for specific letters of the alphabet. |
