16．Internet has become part of young people's life．（46）Areport shows that 38% of students often use the internet．Most of them get  （47）useful （use） information on the internet   （48）and use the internet to help in their studies．But many students don't use it （49）in a good way．Some play games too much，some visit websites （50）that they shouldn't look at．So bad things may happen （51）if students spend too much time on the internet．
（52）It  is important for students to use the internet （53）properly （proper）．Now we have a textbook，which uses many examples to teach students some good ways to use the internet．It gives useful （54）advice （advise）．Some students also make friends on the internet．But if you want to have a face-to-face （55）meeting （meet） with your online friends，let your parents know and meet in a proper place．

分析 互聯(lián)網(wǎng)已經(jīng)成為年輕人生活的一部分．一份報告顯示，38%的學(xué)生經(jīng)常使用互聯(lián)網(wǎng)．他們中的大多數(shù)人在互聯(lián)網(wǎng)上獲得有用信息，并利用互聯(lián)網(wǎng)來幫助他們學(xué)習(xí)．但許多學(xué)生不以一種好的方式使用它．有的經(jīng)常玩游戲，有的訪問一些不該訪問的網(wǎng)站．如果學(xué)生在互聯(lián)網(wǎng)上花費太多時間，那么這類糟糕的事情可能發(fā)生．其實，重要的是讓學(xué)生正確使用互聯(lián)網(wǎng)．現(xiàn)在，我們有一本教科書，它使用了許多例子，教給學(xué)生使用互聯(lián)網(wǎng)的一些好辦法．它提供了寶貴的意見．還有些學(xué)生在互聯(lián)網(wǎng)上結(jié)交朋友．但如果你想與您的網(wǎng)上朋友有一個面對面的交流，就可以讓你的父母知道，并在適當(dāng)?shù)牡胤揭娒妫?/p>

解答 46．答案：A．考查冠詞：句意：一份報告顯示，38%的學(xué)生經(jīng)常使用互聯(lián)網(wǎng)．前文還沒有出現(xiàn)，無須特指．泛指"一份報告"，report輔音音素開頭，因此填a
47．答案：useful．考查形容詞：句意：大部分人在網(wǎng)上得到有用的信息，修飾information用形容詞useful．
48．答案：and．考查連詞：句意：大多數(shù)人從網(wǎng)絡(luò)上得到信息并且用網(wǎng)絡(luò)來幫助學(xué)習(xí)，從這個句子要表達(dá)的意思來看get 和 use是并列的謂語動詞．填and．
49．答案：in．考查介詞短語：句意"但許多學(xué)生不以一種好的方式使用它"in a good way以一種好的方式．答案是in．
50．答案：that．考查從句：句意"有的訪問一些不該訪問的網(wǎng)站"．這是一個that或which引導(dǎo)的定語從句，答案可以是that．
51．答案：if．考查連詞：句意：如果在網(wǎng)上待太多時間，壞事情就會發(fā)生．從上一句話承接下來的一個結(jié)果，但用了情態(tài)動詞may，此空應(yīng)該填連詞來引導(dǎo)一個條件狀語從句．填if．
52．答案：It．考查代詞：句意"重要的是讓學(xué)生____使用互聯(lián)網(wǎng)"．It是形式主語，代替不定式to use the Internet…
53．答案：properly．考查副詞：句意"重要的是讓學(xué)生正確地使用互聯(lián)網(wǎng)．"根據(jù)所給單詞proper正確的，可知，應(yīng)該用副詞修飾動詞use．答案是properly．
54．答案：advice．考查名詞：句意"它提供了寶貴的意見．"．a(chǎn)dvise動詞，useful形容詞，應(yīng)該修飾名詞．答案是advice．
55．答案：meeting．考查詞組：句意"但如果你想與您的網(wǎng)上朋友有一個面對面的交流"，have a face-to-face meeting和…面對面交流，提示詞meet雖有名詞詞性，但have a meeting是習(xí)慣搭配．答案是meeting．

點評 本題要根據(jù)上下文的句子串聯(lián)來選擇合適的詞，特別要注意詞性以及詞形的匹配，大小寫，單復(fù)數(shù)等具體形式．

4．Different Kind of Spring Break
For many American university students，the weeklong spring break holiday means an endless party on a sunny beach．In Panama City Beach，F(xiàn)lorida more than half a million university students arrive during the month of March to play and party，making it the number one spring break place in the United States．
A weeklong party is not for everyone，however，and a growing number of American university students have found a way to make spring break matter．For them，joining or leading a group of volunteers to help solve problems such as homelessness or environmental damage makes spring break a special learning experience that university students can feel good about．
During one spring break week，students from James Madison University in Virginia took part in 15"spring break"trips to nearby states，three others to more distant parts of the United States，and five international trips．One group of JMU students traveled to Bogalusa，Louisiana，to help rebuild homes damaged by Hurricane （颶風(fēng)） Katrina．Another group traveled to Mississippi to organize creative activities for children living in a homeless shelter．One group of students did go to Florida，but not to lie on the sand．They did some work to help protect the native Florida plants．
Students who take part in spring break projects find them very rewarding （值得的）．While most university students have to get their degrees before they can start helping people，student volunteers are able to help people right now without degrees．On the other hand，the buildings or rooms they live or stay are far from attractive．Students often sleep on the floor of a school or church．But they only pay around $250 for meals and transportation，which is much less than some of their friends spend traveling to more traditional spring break hot spots．
Spring break projects appear to be growing in popularity at universities across the United States．Some students take the opportunity to meet new friends．Others want to exercise their beliefs to make the world a better place．Whatever their reasons，these students have discovered something that give them rich rewards along with a break from school work．

61．What‟s the number one spring break place in the United States？Panama City Beach，F(xiàn)lorida．
62．What is the way to make spring break matter for some students？Joining or leading a group of volunteers to help solve problems．
63．How did the students help in Bogalusa，Louisiana？By rebuilding homes damaged by Hurricane Katrina．
64．Where do the student volunteers often sleep？On the floor of a school or church．
65．What makes the spring break projects more rewarding？Student volunteers can help people right now without degrees，spend less money，meet new friends and exercise their beliefs．．

This winter holiday，I took part in a public welfare activity about audism with my classmates from Feb 17to 18．The moment we stepped into the autism center，I was shocked by what I saw．With their heads hanging down，most children stayed silent，paying no attention to what was going on．When we introduced ourselves，they didn't look up at us until their parents had reminded them to do so again and again．At that time，I knew that they would need a great deal of attention．

During our two days of activities，we not only played with these autistic children，but also made every effort to help them．Our group members found as much information as possible on the Internet and discussed every possible way in which we could enter their hearts．In addition，in order to improve their living conditions，we made an online donation．I felt the seed （種子） of loveblooming in me when I received money from others．
