      Learners report two main difficulties in reading, which may be linked. There are too many unknown

words and as a result reading is simply not a pleasure. For some students, even reading in their own

language is a chore.   

     Having a wide vocabulary is essential to making sense of written language. Of course, this is a circular

argument, because the more you read the more vocabulary you learn and the more words you know the

more easily you can read. Don't make the mistake of reading with your dictionary beside you, looking up

every single new or doubtful word. This is laborious and prevents you from practicing the skill of prediction.   

     Sometimes in reading you find a word you know but the sense doesn't seem to fit in. This is not

surprising because words have so many meanings and degrees of meaning. What is more, part of their

meaning is shaped by the words around them. Keep looking at the surrounding words and asking yourself

"what sort of meaning would make sense here?"   

     The more that people study the reading process, the better they can pass on to language learners a range

of advice to choose from. People have learned to read in all kinds of ways. Here is some information that

could help you plan to be a better reader in the foreign language you are studying.   

     1) Work out the general meaning first   

     When people read in a new language they often feel they must take a detailed approach, focusing in every

word, particularly those they don't know. They read as if they were using a microscope, looking carefully

at each of the small pieces (the individual words), but not necessarily seeing the whole picture at first. This is

called the "bottom-up" approach. Other readers try to look first at the big picture(the "top-down" approach),

attending to individual bricks only as necessary, a process that involves some intelligent guesswork. Generally

this second approach is recommended by successful learners.   

     2) Interactive reading   

     Another way of thinking about reading is to describe it as an interactive process, where the text brings

something to you and you bring something to the text. Readers bring together all their knowledge of the

world with what they see on the page in front of them. That is why, when reading in our own language,

we don't need to read every word. We add meaning which is not actually stated.   

     3) From supported reading to independent reading   

     Language learners start by needing considerable support as they read. Textbooks supply this support

in the form of introductions that summaries the contents, glossaries, pictures, explanations of new

grammar points. In your reading you need to move gradually from this support to reading more the text itself.

B. keep looking at the surrounding words

C. look it up in the dictionary each time

D. make sense of it with the help of dictionary

单项选择题

Large parts of the world have not enjoyed the remarkable global progress in health conditions that have taken place over the past century. Indeed, millions of deaths in impoverished nations are avoidable with prevention and treatment options that the rich world already uses. This year, 10 million children will die in low and middle income countries. If child death rates were the same as those in developed countries this figure would be lower than 1 million. Conversely, if child death rates were those of rich countries just 100 years ago, the figure would be 30 million. Today’s tools for improving health are so powerful and inexpensive that health conditions could be reasonably good even in poor countries if policy makers spent even relatively little in the right places.

Recent research for the Copenhagen Consensus identifies several highly cost-effective options that would tackle some of the planet’s most urgent health problems. The most promising investment is in tuberculosis treatment. Some 90 percent of the 1.6 million tuberculosis deaths in 2003 occurred in low-and middle-income countries. Because tuberculosis affects working-age people, it can be a trigger of household poverty. The cornerstone of control is prompt treatment using first-line drugs, which doesn’t require a sophisticated health system. Spending $1 billion on tuberculosis treatment in a year would save 1 million lives. Because good health accompanies higher levels of national economic welfare in the long run, the economic benefits are worth $ 30 billion.

The second most cost-effective investment is tackling heart disease. Heart disease might not seem like a pressing issue for poor nations, but it represents more than a quarter of their death toll. Measures to reduce risk factors other than smoking — high intake or saturated animal fat, obesity, binge drinking of. alcohol, physical inactivity, and low fruit and vegetable consumption — have had little success. Treating acute heart attacks with inexpensive drugs is, however, cost-effective. Spending $ 200 million could avert several hundred thousand deaths, yielding benefits that are 25 times higher than costs.

The third option is prevention and treatment of malaria. A billion dollars would expand the provision of insecticide-treated bed-nets and facilitate provision of highly effective treatment. This would save more than a million child deaths and produce economic benefits worth $ 20 billion.

The fourth alternative for policymakers is to focus on child health initiatives. The best measures are familiar ones expanding immunization coverage, promoting breastfeeding, increasing the use of simple and cheap treatments for diarrhea and childhood pneumonia, and so on.

Even if the costs of all these initiatives were two or three times higher than we estimate, these efforts would still provide amazing opportunities to reduce health inequality and do good in the world.

According to the author, if $1 billion were invested in the prevention and treatment of heart discase, which of the following economic benefits would be produced?()

A.$ 20 billion.

B.$ 25 billion.

C.$ 30 billion.

D.$ 35 billion.
