With the summer holiday just around the corner, it seems like everybody is busy planning their vacations. Here are some tips that can helpyou enjoy your holiday without emptying your pocket:

Travel off-season

Go to your desired destination while the demand is low and takeadvantage of huge discounts. During the peak season, the hotel and flightprices increase quickly, and you'll likely spend more of your vacation timestanding in line due to the rush of tourists.{#blank#}1{#/blank#}

      Websites can help you find discount hotel rooms. Look for placesthat do not charge extra for children if they use the existing bedding. Staywith the locals. If you and your family are going to stay for a longer period,renting a small apartment is a good choice.

Eat like a local

      Why eat at big chain restaurants when you can experiencesomething new?{#blank#}3{#/blank#}

During your family trip, try new food where the locals eat. Thiswill not just save money, but also provide you with a new and differentexperience. For smaller meals and snacks, avoid restaurants and try street foodor other takeout.

      Instead, take buses, railways or subways, which are alwayscheaper. If you are planning to stay for a while, you can consider renting acar. Hiring a car is much easier than carrying your bags everywhere if you aremoving around a lot.

A. Save on hotels.

B. Surf the Internet while traveling.

C. Therefore, avoid buying anything there.

D. So it's best to find out when the off-season starts.

E. Planning your meals is another way to reduce your travelcosts.

F. For this reason, you shouldn't feel ashamed to ask forbargains.

    "If you want to see a thing well, reach out and touch it!"

That may seem a strange thing to say. But touching things can help you to see them better.

    Your eyes can tell you that a glass ball is round. But by holding it in your hands, you can feel how smooth and cool the ball is. You can feel how heavy the glass is. When you feel all these about the ball, you really see it. With your skin, you can feel better. For example, your fingers can tell (辨别) the difference between two coins in your pocket. You can feel a little drop of water on the back of your hand, too. You can even feel sounds against your skin. Have you ever wanted to know why some people like very loud music? They must like to feel the sounds of music.

    All children soon learn what "Don't touch!" means. They hear it often. Yet most of us keep on touching things as we grow up. In shops, we touch things we might buy: food, clothes. To see something well, we have to touch it. The bottoms of our feet can feel things, too. You know this when you walk on warm sand, cool grass or a hard floor. All feel different under your feet.

    There are ways of learning to see well by feeling. One way is to close your eyes and try to feel everything that is touching your skin. Feel the shoes on your feet, the clothes on your body, the air on your skin. At first, it is not easy to feel these things. You are too used to them!

    Most museums are just for looking. But today some museums have some things to touch. Their signs say, "Do touch!" There you can feel everything on show.

    If you want to see better, reach out and touch. Then you will really see!

    The discussion on renewable energy has been going on for at least a decade and people have relied on fossil fuels almost entirely for more than a century. However, the situation when fossil fuels were the most efficient and the cheapest source of energy has been left far in the past. Many countries such as Germany and Sweden have already made significant efforts to fix this situation, employing numerous power plants working on the renewable resources of energy. The most effective among these resources is geothermal（地热的）energy.

    Geothermal energy does not depend on the world's economic and political situation as strongly as fossil fuels do. Besides, extracting（提炼）fossil fuels adds to the price of energy produced from them. Therefore, geothermal energy is much cheaper than traditional ones, saving up to 80% of the costs over fossil fuels.

    Being a renewable resource, geothermal energy produces less waste and pollution than traditional energy sources. In geothermal systems, carbon dioxide makes up about 10% of air produced. Overall, in order to produce the electricity that can be used for one hour, the geothermal systems produce 0.1 pound of carbon dioxide and other harmful gases. For a comparison, a power plant producing from gas produces up to 2 pounds of carbon dioxide into the atmosphere, and those power plants that work on coal（煤）produce an astonishing 3.6 pounds of greenhouse gases.

    Low costs is another reason why using geothermal power plants should be the first choice for many countries. Geothermal heat systems require 25% to 50% less energy for work compared with the traditional systems for heating or cooling. Besides, geothermal equipment is less big: due to the very nature of geothermal energy, geothermal power plants have only a few moving parts, all of which can be easily sheltered inside a relatively small building. What's more, the life span of geothermal equipment is rather long. All these make geothermal power stations easy to build and keep.

    Social media is one of the fastest-growing industries in today's world. Your friends' lives may look more exciting than yours on Facebook, Twitter, and Instagram, but a new research shows it is because they are faking (伪造) it.

    A recent survey has found around two-thirds of people on social media post images to their personal information to make their lives seem more adventurous. And more than three quarters of those asked said they judged their peers based on what they saw on their Instagrm, Snapehat or Facebook pages.

    The British survey, by smart phone maker HTC, found that, in order to make our own pages and lives appear more exciting, six percent also said they had borrowed items to include in the images in order to pass them off as their own. More than half of those surveyed said they posted images of items and places purely to show off, causing jealousy among friends and family.

    Behavioral psychologist Hemmings said the trend was unsurprising due to the rise of social media. "We're living in a world instant communication." she said. "Fashion and style used to live and die in magazines; now people are in search of authentic, peer-to-peer recommendations as well, making social media an equal power house to magazines and newspaper."

    "With images being shared in an instant, we desire to know what our friends are wearing, or what super stars are buying, as soon as they have got them." Such is the influence of social media sites like Instagram, 76 percent of those asked also said seeing items on social influences them to buy them, with men more likely to take style advice and buy what they see.

    There has, in recent years, been an outpouring of information about the impact of buildings on the natural environment. Information which explains and promotes green and sustainable construction design, strives to convince others of its efficacy (功效) and warns of the dangers of ignoring the issue. Seldom do these documents offer any advice to practitioners, such as those designing mechanical and electrical systems for a building, on how to use this knowledge on a practical level.

    Although there are a good many advocates of "green" construction in the architectural industry, able to list enough reasons why buildings should be designed in a sustainable way, not to mention plenty of architectural firms with experience in green design, this is not enough to make green construction come into being. The driving force behind whether a building is constructed with minimal environmental impact lies with the owner of the building; that is, the person financing the project. If the owner considers green design unimportant, or of secondary importance, then more than likely, it will not be factored into the design.

    The commissioning (委任) process plays a key role in ensuring the owner gets the building he wants, in terms of design, costs and risk. At the predesign stage, the owner's objectives and expectations are discussed and documented. This gives a design team a solid foundation on which they can build their ideas. Owners who skip the commissioning process, or fail to take "green" issues into account when doing so, often come a cropper once their building is up and running. Materials and equipment are installed as planned, and, at first glance, appear to fulfil their purpose adequately. However, in time, the owner realizes that operational and maintenance costs are higher than necessary, and that the occupants are dissatisfied with the results. These factors in turn lead to higher ownership costs as well as increased environmental impact.

    In some cases, an owner may be aware of the latest trends in sustainable building design. However, firms should not take it as read that the client already has an idea of how green he intends the structure to be. Indeed, this initial interaction between owner and firm is the ideal time for a designer to outline and promote the ways that green design can meet the client's objectives, thus turning a project originally not destined for green design into a potential candidate.

    Typically, when considering whether or not to adopt a green approach, an owner will ask about additional costs or return for investment. In a typical project, landscape architects, mechanical and electrical engineers do not become involved until a much later stage. However, in green design, they must be involved from the outset, since green design demands interaction between these disciplines. This increased cooperation clearly requires additional cost. However, there may be financial advantage for the client in choosing a greener design. There are examples of green designs which have demonstrated lower costs for long-term operation, ownership and even construction.

Do you have plastic bottles at home？Did you throw empty plastic bottles into the trash，just because you didn't know how to use them？However，there are many interesting things you can do with empty plastic bottles! {#blank#}1{#/blank#}
