7．A team of scientists from University of Freiburg in Germany are developing a shoe with a sensor to automatically tie its laces（鞋带）that could be taken off when users click their heels together．
It's been 26years since we saw them magically tightening Marty McFly's Nike boots in the film Back to The Future．
Now，self-tying shoelaces could actually become a reality this year，proving right one of the film's fantastical predictions for what 2015would be like．
Engineers have designed a shoe that can automatically lace up，adjusting itself to the shape of your foot．
Simply slip the controller on and pressure sensors will tell the‘smart shoe'when your foot is in position，triggering（触发）a tiny motor in the heel that pulls the laces tight．
When you want to take off the shoes，you click your heels together twice and the motor will release a spring（弹簧）in the shoe's tongue，which loosens the laces enough for you to slip them off．
And the invention doesn't even need to be plugged in to charge or have its battery replaced because it runs on power generated by the swing of your foot as you walk•
Engineer K1evis Ylli，of the Institute for Micromachining and Information Technology in southern Gemany，said the shoes could help a variety of different people．
"One focus is that it could be used in shoes for elderly people who have mobility problems，"he said．"But it could also work for children，or as a lifestyle product．"．
The design，which is still in a prototype（雏形）stage，cleverly gets the energy of the foot's swing when opposing magnets in each shoe move past each other．It then uses that power to charge a battery．An hour of walking is enough to tighten the laces once，and it requires no energy to undo the shoes because that relies on the spring alone．

29．Which of the following can be the best title of the textC？
A．A fantastical prediction
B．A great invention in Germany
C．A shoe with self-tying laces
D．A popular lifestyle product
30．What can we learn about the shoesB？
A．They can automatically take off．
B．They can adjust themselves to your foot．
C．They need to be charged once．
D．They have been in design for 26years．
31．From the last paragraph we can knowD．
A．the shoes have been put into use
B．the shoes need power to take off
C．the shoes promise to be popular
D．how the shoes work to produce energy．

4．Ask helpful Hannah
Dear helpful Hannah，
I've got a problem with my husband，Sam．He bought a smart phone a couple of months ago and he took it on our recent ski vacation to Colorado，it was a great trip except for one problem．He has a constant urge （33）to check for next messages； he checks his phone every five minutes!He's so addicted to it that he just can't stand the idea （34）that there may be an important text．He can't help checking even at inappropriate times like when we are eating in a restaurant and I am talking to him!He behaves（35）as if any small amount of boredom can make him feel the need to check his phone even when he know he shouldn't．The temptation to see（36）who is connecting him is just too great．When I ask him to put down the phone and stop（37）ignoring （ignore） me，he say，"In a minute．"but still checks to see if（38）someone has posted something new on the Internet．Our life（39）is interrupted（interrupt）．If we go somewhere and I ask him to have the phone at home，he suffers from withdrawal symptom．May this dependency on his smart phone has become more than an everyday problem．
I recently read an article about"nomophobia，"（40）which is a real illness people can't suffer from the fear of being without your phone!I am worried that Sam maybe suffering from this illness because he feels anxious if he doesn't have his phone with him，even for a short time．
Who would have thought that little devices like these could have brought so much trouble!
Sick and Tired Sadie．
