How to make your bicycle safe?

A number of crimes are against bicycles. About 150,000 bicycles are stolen every year and most are never found. You can prevent this from happening by following a few careful steps.

Basic Security

Never leave your bicycle in out-of-the-way places. Always lock your bicycle when you leave. Secure it to lampposts or trees. Take off smaller parts and carry them with you, for example lights and saddles (车座).

Locks

There are various types of locks. Buy one that has been tested against attack. Ask for a recommendation from a bike shop owner.

Marking

Security marking your bike can act as an obstruction to thieves, which can also help the police find your bicycle. Your postcode and your house or flat number should be included and clearly recorded. This will provide a simple way to identify your bicycle.

Registration

There are many companies that will security mark your bicycle. They will then store your registration number and personal details in their computer database. If your bicycle is found, it will be easy to contact you.

Attention

Keep a record of the bicycle by yourself: its production, model and registration number. You can even take a photograph of it. This will prove the bicycle belongs to you.

【题目】Some inventions are so useful, but seem so simple, that we wonder why no one thought of them long ago.

Post-it Notes were invented about twenty years ago by Art Fry, a scientist at 3M Company. The idea for the product came from an awful experience he often had while singing in his church choir. Fry used pieces of paper as bookmarks to mark the places in his book of songs, but these bookmarks were always falling out. Around that time, Fry heard about a new adhesive (粘合剂) that a colleague, Dr. Spence Silver, had created. This adhesive was special because it was strong enough to hold papers together, but not strong enough to tear the paper when it was removed.

A short time later, Fry realized that his new invention had even more uses than being a great bookmark. He came to this realization when he wrote a note on one of his new bookmarks and attached it to a report he was going to give to a colleague. Soon, co-workers were asking Fry for more of his invention so that they could use the new type of notes themselves.

Fry and some other people at 3M believed so much in the new product that they asked the company to give away thousands of the sticky pieces of paper for trial use. When some salespeople at 3M went to offices and showed workers just how helpful the new type of notes could be, they immediately received many orders. As more and more people discovered how useful Post-it Notes could be, the product took off.

【题目】Tea production in Sri Lanka has thrived for decades. The tea gardens in Hatton, Sri Lanka are actually large tea estates. The best tea usually comes from plants grown on high grounds, the cool hilltops with rows and rows of tea plants. The plants are about one meter apart. The plant is often pruned so that it remains only 60 to 90 centimeters high. Pruning is important because it encourages the growth of tender shoots, or young leaves. It is from these shoots that the best tea is got.

Practically all the tea pickers are women. The estates prefer to employ women pickers because they are more careful. Their thin fingers can easily remove the twin leaves and new shoots from the plant, which are the parts used for processing tea. The pickers carry large baskets into which they throw their pickings. A skilled worker can harvest between 9 to 14 kilograms of tea leaves a day. Usually new shoots can be picked from the plants about every ten or fifteen days.

Processing tea shoots into our familiar dry tea leaves requires great care and skill. There are various methods of processing depending on the type of tea required. For black tea, the young green leaves are first spread out shelves to dry. This process removes much of its water and the leaves become soft. After this, the leaves are passed through heavy rollers. This operation will press the leaves for juices which give the tea both its color and taste. Then the leaves are spread out on floors and left to ferment(发酵)under wet conditions. Fermentation develops the rich taste of black tea. The fermented leaves are then dried with a hot-air blower until they become rolled-up black leaves. The final step is to sort and grade them before the black tea is ready for sale to countries all over the world.

【1The underlined word pruning means .

A. reasonable use of chemicals

B. regular cutting of the plants

C. frequent watering

D. loosening the soil

【2How many processing steps are mentioned in the last paragraph?

A. Six B. Five C. Four D. Three

【3What does the author imply in the passage?

A. Fermentation is a must to enrich the flavour of black tea.

B. Women pickers are welcomed because they can easily find the twin leaves.

C. Tea production has long been prosperous in Sri Lanka.

D. Tea pickings can be done biweekly.
