【題目】A team of scientists from University of Freiburg in Germany are developing a shoe with a sensor to automatically tie its laces(鞋帶)that could be taken off when users click their heels together．

It’s been 26 years 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 2015 would 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(觸發(fā))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(彈簧)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(雛形)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.

【1】Which of the following can be the best title of the text?

A．A fantastical prediction

B．A great invention in Germany

C．A shoe with self-tying laces

D．A popular lifestyle product

【2】What can we learn about the shoes?

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 26 years．

【3】From the last paragraph we can know ____________．

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

【題目】C

Would you like to discover all the corners of the UK, or travel abroad? Maybe you have never tried the motorhome (旅宿車) lifestyle before. Well, read this article and you will know why a motorhome is a good choice.

Nothing is better than a motorhome. It has so many uses that it is considered the most versatile vehicle(交通工具)and it is also very comfortable. If you are thinking about hiring a motorhome this summer, then the best advice is to book it early, especially if you are considering the school holidays. The motorhome hire service is very seasonal and motorhome hire companies will never have extra vehicles available in the summer months.

There are a lot of companies throughout the UK, and some of the big ones have motorhomes spread all over the country. At present, the largest network for motorhome hire is provided by Motorhome which is based in Cambridge. If you are in the UK , you may phone 0800-612-8719 for details of its motorhome hire information. Motorhome has a network of over 500 vehicles all over England, Scotland and Wales.

Most people wishing to hire a motorhome are families that are looking for an alternative(替代品)to a European package holiday, especially as flying now has become more expensive, and is considered to be environmentally unfriendly. There is no doubt that the idea of no-fly holidays is going to become more popular as fewer people think it is safe to fly. This explains why more and more people are choosing to hire a motorhome for their holidays.

【1】This passage is written to explain why it is a good idea to_______

A. take an adventure B. travel to England

C. try a new lifestyle D. hire a motorhome

【2】What does the underlined word“versatile”in paragraph 2 probably mean?

A. Large and comfortable. B. Fast and exciting

C. Having a lot of uses. D. Having a lot of fun.

【改編】【3】Why should you book a motohome early if you want to book one for this summer?

A. Because booking early is much cheaper than before

B. Because summer is usually a very busy season.

C. Because you can arrange your time better.

D. Because students usually book them to earn much money.

【題目】 Dogs are social animals and without proper training, they will behave like wild animals. They will soil your house, destroy your belongings, bark excessively, fight other dogs and even bite you. Nearly all behavior problems are perfectly normal dog activities that occur at the wrong time or place or are directed at the wrong thing. The key to preventing or treating behavior problems is learning to teach the dog to redirect its normal behavior to an outlet that is acceptable in the domestic (馴養(yǎng)的) setting.

One of the best things you can do for your dog and yourself is to train its obedience. Obedience training doesn’t solve all behavior problems, but it is the foundation for solving just about any problem. Training pens up a line of communication between you and your dog. Effective communication is necessary to instruct your dog about what you want it to do.

Training is also an easy way to establish the social rank order. When your dog obeys a simple request of “come here, sit,” it is showing obedience and respect for you. It is not necessary to establish yourself as top dog or leader of the pack (群) by using extreme measure. You can teach your dog its subordinate (從屬的) role by teaching it to show submission to you. Most dogs love performing tricks for you to pleasantly accept that you are in charge.

Training should be fun and rewarding for you and your dog. It can enrich your relationship and make living together more enjoyable. A well-trained dog is more confident and can more safely be allowed a greater amount of freedom than an untrained animal.

【1】Behavior problems of dogs are believed to _________.

A. occur when they go wild

B. be just part of their nature

C. get worse in modern society

D. become a threat to the community

【2】The key to solving dogs’ behavior problems is to _________.

A. teach the dog to perform clever tricks

B. make the dog aware of its owner’s authority

C. enable the dog to regain its normal behavior

D. provide the dog with a pattern accepted by its owner

【3】Why do pet dogs love performing tricks for their masters?

A. To avoid being punished.

B. To show their affection for their masters.

C. To win leadership of the dog pack.

D. To show their willingness to obey.

【4】When a dog has received effective obedience training, its owner _________.

A. can give the dog more freedom

B. will enjoy a better family life

C. can give the dog more rewards

D. will have more confidence in himself

【題目】Steve Sparks was a young successful lawyer when a bruise （挫傷） on one of the legs of his 3-year-old daughter changed his life. The bruise led to a doctor’s visit. The doctor said his daughter was suffering from leukemia (白血病).

Steve said that in a moment his life changed from what restaurant he was going to take his clients (客戶) to lunch to whether his daughter Katie was ever going to see her fourth birthday.

For three years Katie received a lot of treatment at the Nemours Hospital for Children in Wilmington, Delaware and with the help of wonderful doctors, kind nurses, whom Steve and his wife Michelle called heroes, Katie’s leukemia was cured (治愈).

Steve is glad to have made such a choice.
