How far would you be willing to go to satisfy your need to know? Far enough to find out your possibility of dying from a terrible disease? These days that’s more than an academic question, as Tracy Smith reports in our Cover Story.
There are now more than a thousand genetic(基因的)tests, for everything from baldness to breast cancer, and the list is growing. Question is, do you really want to know what might eventually kill you? For instance, Nobel Prize-winning scientist James Watson, one of the first people to map their entire genetic makeup, is said to have asked not to be told if he were at a higher risk for Alzheimer’(老年痴呆症).
“If I tell you that you have an increased risk of getting a terrible disease, that could weigh on your mind and make you anxious, through which you see the rest of your life as you wait for that disease to hit you. It could really mess you up.” Said Dr. Robert Green, a Harvard geneticist.
“Every ache and pain,” Smith suggested, could be understood as “the beginning of the end.”“That ’s right. If you ever worried you were at risk for Alzheimer’s disease, then every time you can’t find your car in the parking lot, you think the disease has started.”
Dr. Green has been thinking about this issue for years. He led a study of people who wanted to know if they were at a higher genetic risk for Alzheimer’s. It was thought that people who got bad news would, for lack of a better medical term, freak out. But Green and his team found that there was“no significant difference”between how people handled good news and possibly the worst news of their lives. In fact, most people think they can handle it. People who ask for the information usually can handle the information, good or bad, said Green.

The tea gardens in Sri Lanka are actually large estates(种植园). 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 metre apart. The plant is often pruned so that it remains only 60 to 90 centimetres 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(加工) tea. The pickers carry large baskets into which they throw their pickings. A skilled worker can harvest between 9 to 14 kilogrammes of tea leaves a day. Usually new shoots can be picked from the plants about every ten or fifteen days.
Processing tea shoots into the 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 o 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 colour 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.
68.In the first paragraph ,the word “pruning” means .
A.regular cutting of the plants
B.frequent watering
C.regular use of chemicals
D.growing the plants high in the mountain
69.One of the reasons why women are employed to do the picking is that .
A.they work harder than men do in the picking
B.they can throw their pickings more easily into the baskets
C.their fingers fit them better for the job.
D.they can more easily find the twin leaves.
70.How many processing steps are mentioned in the last paragraph?
A.Three. B.Four. C.Five. D.Six.
71.What is the writer’s purpose in writing the passage?
A.To introduce various methods of tea processing.
B.To persuade readers to buy tea from Sri Lanka.
C.To tell a story that had happened in the tea gardens.
D.To inform readers of tea growing ,picking and processing.
