As we know, everyone can make mistakes, but don't worry about it. The following is what we should do when we make mistakes.

    ● Just admit (承认）it. Don't think that our mistakes are caused by others. {#blank#}1{#/blank#} Don't blame other people, and don't cheat ourselves, either.

    ●{#blank#}2{#/blank#} In order to stop the problem from getting worse, we should act quickly to solve it. If we don't act and deal with the problem quickly, it'll only make us feel more stressed. Also it is necessary to make a plan of action and correct the mistake according to it. {#blank#}3{#/blank#}

    ●{#blank#}4{#/blank#} Those who have made the most mistakes can get an A, for they are the ones who have learned the most. The more we learn from our mistakes, the cleverer we are.

    ●{#blank#}5{#/blank#}What caused us to make the mistake? How can we avoid making the same mistake in the future? When we act with a method to get a good result, do it that way next time. If we don't, we should stop, think about it, change it and try again.

A. Don't be afraid of failure.

B. Realize that making mistakes is the best way to learn.

C. Solve it at once.

D. Be brave and face the fact that we have made the mistakes.

E. So be away from stress.

F. Think about what we can learn from our mistakes.

G. So decide quickly and act.

    {#blank#}1{#/blank#} When a starving man gets a meal, he begins to think about an overcoat; when a manager gets a new sports car, visions of country clubs dance into view.

    The many wants of mankind might be regarded as making up several levels. {#blank#}2{#/blank#}.

    The first and most basic level of wants is food. Once this want is satisfied, a second level of wants appears: clothing and some sort of shelter. By the end of World War II these wants were satisfied for a great majority of Americans. {#blank#}3{#/blank#} It included such items as cars and new houses.

    By 1957 or 1958 this third level of wants was fairly well satisfied. Then, in the late 1950s a fourth level of wants appeared: the “life-enriching” level. While the other levels mean physical satisfaction－the feeding, comfort, safety, and transportation of the human body－this level stresses mental needs for recognition, achievement and happiness. It includes a variety of goods and services, many of which could be called “luxury” items(奢侈品). Among them are vacation trips, the best medical care, and entertainment. {#blank#}4{#/blank#}

    On this level, a greater percentage of consumer spending goes to services, while on the first three levels more is spent on goods. Will consumers raise their sights to a fifth level of wants as their income increases, or will they continue to demand luxuries and personal services on the fourth level?

    A fifth level probably would be wants that can be achieved best by community action. Consumers may be spending more on taxes to pay for government action against disease, ignorance, crime and prejudice. {#blank#}5{#/blank#} In this way, we can enjoy more fully the good things on the first four levels.

 A．Then a third level appeared.

 B．Human wants seem endless.

 C．When there is money enough to satisfy one level of wants, another level appears.

 D．There are several levels of wants in one's life.

 E．At this stage, we now may seek to ensure the health, safety, and leisure.

 F．Also included here are fancy foods and the latest styles in clothing.

 G．Different people have different wants on each level 

    Many people think of guys as being carefree when it comes to their appearance . But in fact , a lot of guys spend plenty of time in front of the mirror . They care just as much as girls do about their body image.

    Body image is a person's opinions and feelings about his or her own body and physical appearance. {#blank#}1{#/blank#} You appreciate your body for its capabilities and accept its imperfections.

{#blank#}2{#/blank#} Here are some ideas:

    Recognize your strengths. Different body types are good for different things. What does your body do well? Maybe your speed, strength, or coordination makes you better than others at a certain sport. That may be basketball, table tennis, mountain biking , dancing , or even running . Or perhaps you have non-sports skills, like drawing, painting , singing , playing a musical instrument , writing , or acting . {#blank#}3{#/blank#}

    Exercise regularly. Exercise can help you look good and feel good about yourself. Good physiques（体形）don't just happen . {#blank#}4{#/blank#} A healthy habit can be as simple as exercising 20 minutes to 1 hour three days a week . Working out can also lift your spirits .

    Respect your body ! Practicing good habits – regular showering ; taking care of your teeth , hair , and skin ; wearing clean clothes , and so on – can help you build a positive body image .

    When it comes to benefits of volunteering, a lot of people think it's all about the warm feelings after helping someone. {#blank#}1{#/blank#} For example, volunteering...

1）Teaches you new skills

    From helping make websites to teaching kids languages, to arranging events for charity, volunteering can really be almost anything.{#blank#}2{#/blank#} And through overcoming these you learn and start to master completely new skills.

2）Can be relevant work experience

    Something that seems to stop many is that experience often seems to be a prerequisite (必备条件) for some jobs.{#blank#}3{#/blank#} There's many a journalist that gets his or her start through volunteering for a college or university paper, and that's not at all the only profession this applies to.

3）Can be therapeutic (治疗的)

    One of my close friends has completely transformed since she started working for disabled kids.{#blank#}4{#/blank#} It allows you to see the world and other people from a whole different point of view, which in turn can make you grateful for what you already have and see your own personal value.

4）Helps you expand your network

    One of the great things for volunteering is that you meet a wide variety of people.  {#blank#}5{#/blank#} Sometimes it's very convenient to have a broad network.

A. Volunteering helps you grow as a person.

B. As it turns out, that's far from the only benefit.

    For a bird, to fly hundreds or thousands of miles each spring and fall is a difficult and dangerous journey, one that not all birds can survive. {#blank#}1{#/blank#} There is more than one single reason for different birds to migrate(迁徙), but it all comes down to survival.

    Birds are migrating for a meal.

    For all birds, one of the main driving forces behind migration is food. If all birds were to stay in the same places year-round, food there would become not enough. {#blank#}2{#/blank#} But as the food supplies decrease in the fall, they return to the southern areas.

    {#blank#}3{#/blank#}

    Over millions of years, birds have developed different migration patterns, times and destinations. This helps birds take advantage of a wide variety of suitable conditions to raise their young, which increases the survival chances of the young birds.

    Birds are migrating because of climate changes.

    Changes in climate can affect migration. Many birds leave the Arctic for example, when temperatures begin to fall. They need warmer habitats. Similarly, the hottest regions can be an unpleasant environment for raising young birds. {#blank#}4{#/blank#}

    Birds are migrating because of predators.

    Habitats that have rich food sources also attract a greater number of predators who may kill birds. {#blank#}5{#/blank#} Many birds even migrate to specialized habitats that are nearly inaccessible to predators, such as coastal cliffs or rocky offshore islands.

A．So why do birds migrate?

B．Birds are migrating for their young.

C．So how do young birds migrate?

D．Birds are migrating because of diseases.

E. It is beneficial to lay eggs further north in cooler areas.

F. Birds that migrate to different habitats can avoid being eaten by predators.

G. As food sources are rich in the north each spring, millions of birds migrate from south to those areas.

    3D printing is becoming more and more popular. We are now able to print things such as clothing, musical instruments and so on.{#blank#}1{#/blank#} Some scientists are trying to revolutionize the dining experience by doing this. They hope that having a 3D printer in the kitchen will become as commonplace as the microwave or blender. Scientists say that they are easy to use: {#blank#}2{#/blank#} You can also modify the instructions to make the food exactly how you want it. This means that it would be very quick and easy to create tasty and nutritious meals.

    {#blank#}3{#/blank#}There would be less need for traditional growing, transporting and packaging processes as food production would be a lot more efficient.

    Printing food could also help people who suffer from dysphasia（言语困难）. They could program the printer to print softer versions of their favourite foods so that they would not have trouble swallowing them.

    However, some people think that a future of 3D-printed food would be a disaster. {#blank#}4{#/blank#}Imagine a world where there was no need for farming or growing crops and the same tastes and textures could be printed from a raw 'food ink'. Likewise, traditional cafes and restaurants might lose business.{#blank#}5{#/blank#} Is it really possible to get the nutrients we need from food-based inks and gels?

    What's more, cooking and eating together with family and friends will disappear. It is hard to imagine a world where the pastime of cooking is dead and meals can be created at the touch of a button.

A. It will create many jobs.

B. It could take away many jobs.

C. Also, there are concerns about the nutritional value of printed food.

D. You simply have to select a recipe and put the raw food 'inks' into the printer.

E. Using 3D printers to create your meals would also be saving the environment.

F. But can you imagine printing food?

G. Printing food is great for your health.
