    Even if you’re not a hard-core Greenie, there are small acts you can take every day to save both the earth and your 1 . Going DIY with cleaning products is a good way to start. You can use 2 at home that won’t cost you any extra money–and that work just as well as the store-bought stuff. Vinegar cuts grease on stove tops and oven doors, and can even whiten your 3 and remove stains from clothes. In the kitchen, going green can save you money and keep you 4 . Cooking at home can cut down the cost of eating out, as well as the takeout containers you bring home. Buying produce and other raw foods cuts down on 5 that ends up in landfills. You can also look for products that use 6 or biodegradable packaging. You can even use some of the items you 7 in the trash to upcycle. Plastic grocery bags can be used for all kinds of craft projects. It’s easy to ignore, but a great amount of energy gets wasted around the house. You can 8 large appliances and other devices that aren’t being used. Changing out your light bulbs is another way to save money. CFL light bulbs are more 9 at first, but they use much less energy than incandescent light bulbs, and last at least eight times longer than regular bulbs. 10 on natural light is another way to make your light bulbs last longer – so open your blinds and enjoy the sunlight!

    中国大学MOOC: A well-written Introduction usually follows a clear logic. It often begins with the general background, followed by gaps in the research, specific questions addressed in the paper, and new approaches adopted, and ends with the research objectives of the study. Reorganize the different parts of the following Introduction. (请按照你的排序,直接输入大写字母,字母之间没有空格或标点符号)A. Growing interest in WPCs has been established by increasing numbers of publications including research papers, text books, review articles and patents. The competitiveness, performance and appropriateness of wood fibers employed as reinforcements in WPCs have been explored by considering the roles of surface modifications and fiber properties on the mechanical, thermal, and physical properties of WPCs. B. However, a review of the available literature indicates that an insightful understanding of how the properties of wood fibres, surface modification, polymer matrix and compounding technique influence the interface and functional properties of WPCs has not been gained. C. Finally, the implications of the findings of this study for the development of design and materials selection criteria for fabricating WPC parts are discussed in an attempt to ensure an efficient sustainable materials and process management practice. D. Research on wood polymer composites (WPCs) is attracting wider attention because stringent government environmental regulations are compelling industries employing inorganic fillers as reinforcements in polymer composites to search for less expensive, renewable and biodegradable alternative materials. E. In an attempt to increase the competitiveness of WPCs for industrial applications, the present work identifies and elucidates various factors influencing their functional performance by analyzing the associated interfacial bonding mechanisms and the functional properties.(请按照你的排序,直接输入大写字母,字母之间没有空格或标点符号,如:ABCE)
