[单项选择]

Most people who develop Lyme disease, a tick-born infection that’s endemic in parts of the Northeast and Midwest, are easily cured by taking an antibiotic like doxycycline for a couple of weeks. But for years a debate has raged over what to do about patients whose symptoms (fatigue, mental confusion, joint pain) never seem to clear up. One small but vocal group of doctors and patient advocates believes that Lyme’s corkscrew-shaped spirochetes have tunneled deep into their victims’ bodies and can be eradicated only with intensive antibiotic treatment over many months. Another group believes, just as adamantly, that the bacteria are long gone, making further treatment with powerful antibiotics-- which can lead to potentially fatal infections or blood clots--positively dangerous.
Now comes word of two studies in the New England Journal of Medicine that show that long-term antibiotic treatment is no better than a placebo for folks with chronic Lyme disease.
A. even the patients doubt the antibiotic treatment
B. doxycyeline has been regarded as the most effective
C. doctors disagree as to the effect of strong antibiotics
D. moderate antibiotics are better than intensive ones

Directions:
Read the following text carefully and then translate the underlined segments into Chinese. Your translation should be written clearly on ANSWER SHEET 2.
Being a good parent is harder now that it has ever been before. In pressurized modern lives, demands to be a fulfilled individual, and a good partner and a good worker, take no account of being a good parent. (46)We haven’t left space for the nurturing parents to care for their children and provide the kind of care that their children need, resulting in the fact that many families in the western world just don’t work.
Most of us have a bit of yearning for a table full of children descending neatly in size, the older ones helping the younger ones. Let’s control our nostalgia: that" traditional family" had many faults, not least in the roles it imposed on females. (47) The problem is that in the last generation or so we’ve come to assume that wom

Agitated Sunspot Cause

If the lights in your house keep flickering, blame frequent sunspots.
A sunspot is actually charged particles flying at the speed of 3 million kilometers an hour out of the surface of the sun to form sun storms.
Every 11 years, the sun, as its energy accumulates inside up to a certain point, will send out streams of charged particles. (46) .
One is that the magnetic field of the earth is much disturbed because of the sun’s interference in the ionosphere, which is 80 to 500 kilometers above the earth. Wireless short-wave communication, which depends on the wave’s reflection against this layer of atmosphere, is likely to be jammed. (47) .
Scientists also say that the active movement of the charged sun storm also has earthquakes. According to a research conducted by the Russian scientists from 1957 to 1960, the frequency of earthquakes can be linked to the movement of t
