17．In my free time，I really like （66）surfing （surf） the Internet．When I get home from work，I turn on my computer，wait until it boots up（啟動(dòng)）（67）completely （ complete），and then I go online．I usually check my email first and then write a few（68）messages（ message） to family and friends．I sometimes scan the local news headlines at my favorite news Website and read up on the（69）latest （late） local and international news．This Website often provides video news clips（片段） （70）that\wich you can view online．I sometimes order products or service online to save money and time instead （71）of going to a store and（72）buying（buy） what I'm looking for．For example，I （73）ordered  （order）a digital camera online the other day and saved about $50．Whatever I do，I realize that there are problems with using the Internet including scams（詐騙），identify theft，and viruses，so I'm very careful not to give out my （74）personal （person） information．Furthermore，I don't download or open files I don't recognize．Using the Internet can be fun and a convenient way of shopping and finding out new information，（75）but you just need to be careful．

分析 我空余時(shí)間喜歡上網(wǎng)，收發(fā)郵件，瀏覽國(guó)內(nèi)外的新聞，還可以購(gòu)物．但網(wǎng)絡(luò)上也有一些詐騙和病毒，因此對(duì)個(gè)人信息一定要注意．

解答 答案：66．surfing；考查動(dòng)詞搭配．like doing sth喜歡做某事． 
67．completely；考查副詞．句中complete修飾動(dòng)詞boot up，要用副詞形式． 
68．messages；考查名詞．句中有a few修飾，開始名詞要用復(fù)數(shù)形式． 
69．latest；考查比較級(jí)．句意表達(dá)的是最新的消息，要用最高級(jí)形式．
70．that\wich；考查連詞．句中you can view online修飾名詞clips，是一個(gè)定語(yǔ)從句；從句缺少賓語(yǔ)，且先行詞clips指物，要用that或which來引導(dǎo)． 
71．of；考查短語(yǔ)搭配．instead of代替，常用短語(yǔ)． 
72．buying；考查動(dòng)名詞．句中buy作介詞of的賓語(yǔ)，要用動(dòng)名詞形式．
73．ordered；考查時(shí)態(tài)．句意表達(dá)的是過去的動(dòng)作，要用一般過去時(shí)態(tài)． 
74．personal；考查形容詞．句中person修飾名詞information，要用形容詞形式；personal information個(gè)人信息． 
75．but；考查連詞．句意表達(dá)的是轉(zhuǎn)折，要用but來連接．

點(diǎn)評(píng) 語(yǔ)法填空題是考查學(xué)生的語(yǔ)言運(yùn)用能力．解題時(shí)，要在理解文章的基礎(chǔ)上，靈活運(yùn)用語(yǔ)法知識(shí)，如詞性，時(shí)態(tài)，名詞單復(fù)數(shù)，連接詞，代詞，冠詞等判斷空白處應(yīng)填寫的內(nèi)容．答完后，還要通讀全文，核對(duì)所填單詞形式是否正確，是否符合語(yǔ)境．

12．In its first ever National Building Competition，the U．S．Environmental Protection Agency （EPA） challenged the teams from across the nation to cut wasteful energy use in buildings where they live and work．Family and commercial ladings together consume 40 percent of U．S．energy and the Obama Administration is eager to show how that load can be reduced．
In recent remarks at a university．President Barack Obama promoted a plan that could help commercial buildings achieve greater energy efficiency （效率）．
"Making our buildings more energy-efficient is one of the fastest，easiest and cheapest ways to save money，fight against pollution and create jobs right here in the United States of America，"he said．He also inspected the research labs where scientists are working on new technologies designed to cut energy waste in commercial buildings．
Stores like the Sears department store in Maryland，which took second prize in the contest，are already using some of those technologies．As part of the store's bid to cut its energy use，every one of the building's 24 rooftop AC （交流電） units was checked and repaired．Every light bulb-all 15，000 of them-was replaced with a more efficient one．And sensors were installed （安裝）to shut lights off in offices and storerooms when no one is around．Taken together these changes helped the Sears store reduce its building energy consumption by more than one-third and cut electric bills by $ 46，000．
Office buildings can also achieve impressive energy savings．The tenants of a 12-story building in Virginia managed to cut the building's energy consumption by 28 percent as part of the EPA competition．
