13．If your child has mobile internet access，it will be more difficult to monitor（監(jiān)督） and control his or her internet use．Kids are turning to the internet for everything from hanging out with friends to shopping，which makes it harder for parents to keep track of their online activities．Fortunately，there are many choices for controlling what your kids see on their computers，laptops，and mobile devices．
Content blockers and filters are great tools to use for younger kids．They allow you more control over where they go and what they do online．A content blocker can block some unhealthy websites or limit a child's search to the kind of sites．A content filter can scan sites and pictures and block those sites that contain certain words，key phrases，or content．
Consider tracking software for older teenagers．This software enables you to see which sites your children have visited，tracking their path online．This tool gives young people more freedom to explore the Internet，but it also allows you to check that they are using the internet responsibly．Let your teenagers know that you trust them，but that you will be regularly checking that they are visiting appropriate sites online．
Even if you use content blockers，filters，and trackers，you know that a lot of kids figure out ways to get around these，so it's important to remain alert（警惕的）．Remember that not all adult sites can be identified by blocker，filter，or tracker software．That's why it's important to talk to your kids about what to do when something inappropriate or scary comes up．Nothing can replace involvement and supervision（監(jiān)督） by adults．Keep monitoring how your kids use the internet on a regular basis without getting into the role of internet traffic police．

解答 BCABD
71．B．主旨大意題題．通過閱讀整篇文章可知本文主要講了監(jiān)控和控制孩子網(wǎng)絡(luò)使用的一些選擇和注意事項等內(nèi)容，故選B．
72．C．細節(jié)理解題．根據(jù)Content blockers and filters are great tools to use for younger kids，使用網(wǎng)絡(luò)內(nèi)容的阻擋和過濾是一個不錯的工具；故選C．

1．The USA is a land of immigrants．Between 1815and 1914，the world witnessed the greatest peaceful migration in its history：35million people，mostly Europeans，left their homelands to start new lives in America．Why did these people risk everything by leaving their homes and families？
First，what forced emigrants to make the decision to leave？One major cause for European farmers to leave was the rise in population which in turn led to land hunger．Another was politics．There was an increased taxation（稅收） and the growth of armies，and many young men fled eastern Europe to avoid being forced to join the army．
Physical hunger provided another pressing reason．Following the collapse （衰退）of the economy of southern Italy in the 1860s，hundreds of thousands decided to start a new life in America．Religion also encouraged millions to leave the Old World．
In short，people chose to leave their homes for social，economic and religious reasons．As a result，by 1890among a total population of 63million，there were more than nine million foreign-born Americans．
But what were the attractions？First of all，there was the promise of land which was so scarce in Europe．Next，factories were calling for workers，and pay conditions were much better than back home．Men were needed to open up the West and build the long railroads，and new towns needed settlers to live in and to develop business．There was the space for religious people to practice their faith in peace．
This immigration meant that by around the 1850s Americans of non-English had started to be more than those of English．As we know，there were losers．To start with，there were those unwilling immigrants，the slaves who had been used as a source of cheap labour．Nor should we forget the equally unlucky American Indians．By 1860there were 27million free whites，four million slaves and a mere 488，000free blacks．
Nowadays，the USA is still seen by millions as the Promised Land．As always，it remains an attractive place to those who think it will offer them a second chance．

31．What is not the cause for people to leave their homeland？B
A．The search for religious freedom．
B．The search for adventure．
C．Unwillingness to join the army．
D．Economics．
32．Why was life of the 19th Century European farmers difficult？D
A．There was no land．
B．There was no peace．
C．The population had gone down．
D．There were too many of them．
33．Which of the following was not an attraction of the USA？B
A．Employment            B．A healthy life
C．freedom of religion   D．Business opportunities
34．What is the topic of this passage？B
A．The USA is still seen by millions as the Promised Land．
B．The USA is a land of immigrants．
C．Religion encouraged millions to leave the Old World．
D．About one-eighth of non-native born Americans live in the USA in 1890．
35．The American IndiansD．
A．were as fortunate as the slaves
B．were more unfortunate than the slaves
C．were the most unfortunate
D．were as unfortunate as the slaves．

8．"There is nothing either good or bad，but thinking makes it so．"-William Shakespeare，Hamlet．One of the greatest sources of unhappiness，in my experience，is the difficulty we have in accepting things as they are．
　　When we see something we don't like，we wish it could be different-we cry out for something better．That may be human nature，or perhaps it's something that's ingrained in our culture．
An example：in my recent article，A Beautiful Method to Find Peace of Mind，quite a few people thought my view was too negative because I said you should expect people to mess up，expect things to go differently than you planned，and that you should accept that willingly．
It's too negative to expect things to go wrong，they said．However，it's only negative if you see it as negative，if you judge it as bad．Instead，you could accept it as the way the world works-as the way things actually are．And try to understand why that is，and embrace it as it is．Accept these things as they are，and try to understand why they're that way．
Does it mean you can never change things and make this world a better place？Not at all．But not because the world is full of misery，but because that's the path you choose to take，because you enjoy that path and the process of change．
　　Try a different approach：accept，and understand．It might lead to some interesting results．
63．What does the underlined word"ingrained"in the second paragraph mean？C
A．celebrated       B．followed         C．rooted       D．liked
64．What does the author mean by saying the underlined sentence in the third paragraph？A
A．People should take the world as the way it actually works．
B．The world is negative if people see and judge it as negative．
C．In current society we can expect nothing but mess-up people and go-wrong things．
D．We must try to understand what is nature of the world．
65．According to the article，people change the world becauseB．
A．the world is full of misery              B．they enjoy the process of change
C．they can't understand the world         D．they are kind people
66．Which of the following titles best sums up the whole passage？D
A．Change the world
B．Heal the world
C．Cherish the world
D．Accept the world．

5．A"talking kitchen"teaches students how to cook French food and speak French at the same time．Researchers at New Castle University in the United Kingdom have developed the French Digital Kitchen．Professor Paul Seed House and Patrick Olivier led the project．Professor House tells us that it works like a satellite navigation（導(dǎo)航） system in a car，which direct us how to get to your destination．
The kitchen equipment and tools use motion sensor（動作傳感器） technology．The sensors help a computer guide the students through instructions in French．
This is how the system works．The system can tell whether you've done what you were asked to do or not．For example，the system tells you to take some butter and cut it with a knife．There's a sensor on the package containing the butter so it can tell where the butter's being moved．The sensor in the knife not only knows that the knife is moving，but it also knows what motion the knife is making．So it can know whether the knife is cutting or not．And it doesn't go on to the next step of the program unless you've done what it sense you've done．
Students can ask the computer to repeat the instructions or translate them into English．There are vocabulary lessons before and after the cooking．
Professor House says the French Digital Kitchen turns the process of learning language into a real-life experience．"Here you're taking itout of the classroom and you're actually using the language to produce something that you can eat at the end of it．It's very enjoyable．"
The system could be available for sale by the end of 2013．Adding the technology to a new kitchen could add about ten to twenty percent to the building costs．The researchers have also been given money to develop programs in six other languages，including English，Italian and Spanish．
56．The"talking kitchen"developed by New Castle University is mainly aimed atC．
A．helping students who love French food
B．helping house owners prepare their meals
C．helping learners who study French as a foreign language
D．helping housewives who want to learn cooking French food．
57．The third paragraph mainly tells usD．
A．what the system is                       
B．how the system was invented
C．what a motion sensor is

A．French food                              
B．The process of cooking and learning
C．The process of listening and translating         
D．French culture
