TrackR even comes with a double-sided glue so you can stick it to your laptop or under your bike seat.Track down and punish the thieves who steal your expensive things!
?  How much does it cost?

3.My mother sat in silence,shocked by my guided tour of websites of adventurous families,who bike around the world for charity,sail the globe in search of their roots or see the world through children's eyes.We found many people on boats,bikes and foot,showing that adventure doesn't have to die when a new life is created.As one of my friends says,‘This is your one and only chance to explore the world with your children as they are now.'
‘Mum,'I began awkwardly.‘We're going to travel across New Zealand.Two bikes,two trailers(拖车),two toddlers(学步的孩子) and 2,000 miles.'
‘Two thousand nappies(纸尿裤)more like.'
My mother wasn't the only one to raise objections.While friends and family were impressed by our bravery,they were horrified at what it would involve.‘No nursery,no babysitters,no bath time,no peace,no escape…'And that was before we mentioned the real difficulty:pulling 50kg of trailer,toddler and baggage.And of course the nappies.
‘Is there anything I can say to put you off?'my mother asked.
‘No,Mum,'I replied firmly.
‘Well,we'll see about that.'
The challenge of dealing with my mother's phone call about potential disasters is as great as anything we may have to face on the road.Meanwhile,we rush to toilet-train both children to avoid the nappy carrying.Among the voices of doubt and disapproval,I still sometimes wonder if we are mad,but know we aren't mad alone.We have now been in communication with many of the families I showed my mother on the web.And we can feel our own voice getting stronger and more confident with their encouragement,advice and support.
Now we know there are so many families out there adventuring,we're already developing ideas for a world tour to meet some of these families and talk with them about their experiences and spread the word about the possibilities for independent family adventure.As a friend of ours said,‘The only limit is the parents'imagination.'We intend to let ours run wild.

28.What made the author's mother surprised?B
A.There're so many things to view on the Internet.
B.So many parents travel with their small children.
C.There're so many different ways to see the world.
D.The author made so many friends on the Internet.
29.When the author's friends knew her travel plan,they feltC.
A.delighted   
B.curious         
C.worried
D.excited
30.When the author is travelling,her mother phones her toC.
A.offer her advice on training children
B.help her get in touch with friends
C.persuade her to stop travelling
D.make sure she isn't mad
31.According to the last paragraph,the authorD.
A.is planning a reunion party with her family
B.has already made a detailed plan for a world tour
C.is concerned that her imagination may cause problems

18.In modern society there is a great deal of argument about competition.Some value it highly,believing that it is responsible for social progress and prosperity (繁荣).Others say that competition is bad; that it sets one person against another; that it leads to unfriendly relationship between people.
I have taught many children who held the belief that their self-worth relied on how well they performed at tennis and other skills.For them,playing well and winning are often life-and-death affairs.In their single-minded pursuit(追求)of success,the development of many other human qualities is sadly forgotten.
However,while some seem to be lost in the desire to succeed,others take an opposite attitude.In a culture In modern society there is a great deal of argument which only values the winner and pays no attention to the ordinary players,they strongly blame competition.Among themost vocal are youngsters who have suffer under competitive pressures from their parents or society.Teaching these young people,I often observe in them a desire to fail.They seem to seek failure by not trying to win or achieve success.By not trying,they always have an excuse:"I may have lost,but it doesn't matter because I really didn't try."What is not usually admitted by them is the belief that if they had really tried and lost,that would mean a lot.Such a loss would be a measure of their worth.Clearly,this belief is the same as that of true competitors who try to prove themselves.Both are based on the mistaken belief that one's self-respect relies on how well one performs in comparison with others.Both are afraid of not being valued.Only when this basic and often troublesome fear begins to disappear(缓解) can we discover a new meaning in competition.

32.What does this passage mainly talk about?B
A.Competition helps to set up self-respect.
B.Opinion about competition are different among people.
C.Competition is harmful to personal quality development.
D.Failures are necessary experiences in competition.
33.The underlined phrase"the most vocal"in Paragraph 3 meansC.
A.those who try their best to win.
B.those who value competition most highly.
C.those who are against competition most strongly.
D.those who rely on others most for success.
34.What is the similar belief of the true competition and those with a"desire to fail"?A
A.One's worth lies in his performance compared with others.
B.One's success in competition needs great efforts.
C.One's achievement is determined by his particular skills.
D.One's success is based on how hard he has tried.
35.Which point of the view may the author agree to?D
A.Every effort should be paid back.
B.Competition should be encouraged.
C.Winning should be a life-and-death matter.
D.Fear of failure should be removed in competition.

Another is a clean water rule to protect small waterways and wetlands from development by the Environmental Protection Agency.
Trump has said he wants to cancel and replace a third policy,the national health care law,known as"Obamacare."
The Trump administration has promised other major changes.In education,for example,there are plans to give parents more choices in selecting schools for their children,including private,religious schools.
