2．Here in Vancouver，you're in Canada's warmest part．People say it is Canada's most beautiful city，（73）surrounded by mountains and the Pacific Ocean．（74）Skiing in the Rocky Mountains and sailing in the （75）harbour make Vancouver one of Canada's most popular cities to live in．Its population is（76）increasing rapidly．The coast （77）north of Vancouver has some of the oldest and most beautiful （78）forests in the world．It is so wet there that the trees are （79）extremely tall，some（80）measuring over 90metres．

分析 本文主要介紹了加拿大美麗的港口城市溫哥華的一些情況；其中包括溫哥華的氣候，地理位置，人口狀況及其成為最受歡迎的居住城市之一的原因等．

解答 答案：
73．surrounded    考查句意理解以及過去分詞     本句的意思是：人們說它（溫哥華）是加拿大最美麗的城市，被群山以及太平洋環(huán)繞著；此處意為：環(huán)繞，圍繞；在句中作后置定語(yǔ)，修飾名詞 city，由于動(dòng)詞surround與該名詞構(gòu)成被動(dòng)關(guān)系，故用過去分詞surrounded．
74．Skiing    考查句意理解以及動(dòng)名詞     此處指的是：在落基山脈滑雪，由于此處與sailing in the （75）一起在句中作并列主語(yǔ)，故二者在形式上應(yīng)保持一致，故用動(dòng)名詞Skiing．
75．harbour    考查句意理解以及名詞    本句的意思是：在落基山脈滑雪與在港灣航行使得溫哥華成了最受歡迎的居住城市之一；此處指的是溫哥華港灣，故名詞harbour．   
76．increasing     考查上下文句意理解以及時(shí)態(tài)   根據(jù)上一句提到：溫哥華成了最受歡迎的居住城市之一，可知此處的意思應(yīng)是：現(xiàn)在它的人口在迅速增長(zhǎng)，所以這里應(yīng)使用現(xiàn)在進(jìn)行時(shí)"is/am/are+doing"，故填現(xiàn)在分詞increasing．
77．north    考查句意理解以及名詞     本句的意思是：溫哥華北部海岸有一些世界上最古老和最美麗的森林；故填名詞north．
78．forests    考查句意理解以及名詞    承接上一句可知，此處指的是：一些世界上最古老和最美麗的森林；故用復(fù)數(shù)名詞forests．
79．extremely    考查句意理解以及副詞   本句的意思是：那里很潮濕，樹木長(zhǎng)得非常高；此處用來(lái)修飾形容詞tall，指的是：樹木長(zhǎng)得非常高；故用副詞extremely．
80．measuring    考查現(xiàn)在分詞在獨(dú)立主格結(jié)構(gòu)中的用法     這里的意思是：樹木長(zhǎng)得非常高，有些高達(dá)90米；此處為獨(dú)立主格結(jié)構(gòu)在句中作狀語(yǔ)；其中some與measure構(gòu)成邏輯上的主謂關(guān)系，故用現(xiàn)在分詞measuring．

點(diǎn)評(píng) 本題主要考查了各種語(yǔ)法在短文中的具體運(yùn)用．做本題時(shí)，需要在正確理解短文的前提下，逐句分析句意以及所考查到的語(yǔ)法現(xiàn)象；因此在平時(shí)的學(xué)習(xí)中，應(yīng)熟練掌握各種語(yǔ)法知識(shí)，其中包括詞法，句法，各種時(shí)態(tài)語(yǔ)態(tài)以及虛擬語(yǔ)氣等．

7．One should be moderate in all things．Moderation is always the safest way to do things，and a virtue we should have．Let's take the student life for example．There are some students who study too hard and play too little，while there are others who play too much and study too little．On the one hand，it is harmful to his health if he has too few physical exercises，and on the other hand，it is harmful to his mind if he plays too much．
    In the matter of eating，one also should be moderate．Do not eat too much or too little．Eating too much will make you sick，while eating too little will make you week．
The man of progress is he who neither has too high opinion of himself nor thinks too poorly of himself．If he thinks too highly of himself，he is surely to become very proud，but if he has too poor an opinion of himself，he will have no courage to make an advance．Both conditions above will make you lose your aim in life．A broadminded man is he who always moves within the orbit of reasonableness．In any activities in one's life，moderation is one of the best ways to enjoy real happiness

14．Trees are useful to man in three important ways：they give him wood and other useful things，they give him cool places，and they help to stop drought and flood．
  Unluckily，in many parts of the world，man has not found that the third of these points is the most important．Man wants to make money from trees，so he has cut them down in large numbers，only to find that without them he has lost the best friends he had．And also，he is usually too careless to plant and look after new trees．So the forests slowly disappear．
  This does not only mean that man will have fewer trees．The results are even worse：for where there are trees，their roots break up soil---make the rain in---and also bind the soil，thus stopping it from being washed away easily； but where there are no trees，the rain falls on hard ground and flows away，causing floods and carrying away the rich top-soil．When all the top-soil is gone，nothing is left but useless desert．
21．The most important points of trees to man isB．
A．they help him to make money
B．they help him to stop drought and floods
C．they give him wood and other things
D．they give him cool
22．In many places forests slowly disappear becauseC．
A．many trees have been cut down by man
B．new trees are not well looked after

B．there are too many rainfalls

11．Security-for the information on your smart phone，as well as for the phone itself-is a hot topic these days．The truth is that you're packing a lot of sensitive information on your phone，and you should keep it safe．
When it comes to physical security，iPhone users would do well to download Find My iPhone，a free app from Apple that allows you to visit a website and see your （lost，stolen or misplaced） phone on the map．You can then sound an alarm，send a message that will pop up on its screen，lock the phone or erase all your data．
Android does not have an exact equivalent（等價(jià)物），but there are plenty of alternatives．A free app called Lookout offers the findmyphone feature．The paid version allows you to wipe the data from your phone remotely．
Then there is your coffee shop's WiFi network．Anyone with minimal technical expert skill can snoop on（窺視） people using shared wireless networks，harvesting passwords and other personal data．Lookout will caution you when you've logged on to an insecure network，but cannot protect you once you're there．
In order to protect yourself on such networks，you can use a virtual private network，or VPN．This turns all your activity into nonsense to anyone trying to read along with you from across Starbucks．It also keeps websites from tracking you and，if you're travelling，allows you to get access to sites that may be blocked in other countries．
If you have an iPhone，the simplest VPN app is probably Hotspot Shield，whose distinguishing feature is said to be that it automatically kicks in each time you start browsing （瀏覽），as opposed to other VPN apps that require you to start them up manually（手動(dòng)地）．This matters，because even if you decide you want a VPN app，you want to spend approximately zero time thinking about it．For the most part，that was true of Hotspot Shield，though occasionally it took a while to connect or temporarily lost connection without warning．I found myself having to turn the app on and off sometimes，which involved setting my phone constantly．
If even reading about the settings on your phone drive you crazy，then it is probably best to stay away from a VPN app．But if you're the type who can't resist checking your bank balance from your corner bar，the hassle（麻煩） may be preferable to the risk．
24．Which of the following can warn you against the insecure network？C
A．Android．
B．VPN．
C．Lookout．
D．Find My iPhone．
25．By using VPN，users canD．
A．find their lost phones on the Internet
B．remove all the data from the phone remotely
C．check the bank balance now and then
D．save their browsing from being tracked
26．The underlined word"that"in Para.6refers to the fact thatA．
A．a(chǎn) VPN app kicks in automatically
B．the users start VPN apps manually
C．the app takes a while to connect
D．users spend no time thinking about it．
