[单项选择]People from large families have an increased risk of stomach cancer, suggests a study that followed more than 7,000 Japanese-American men for 28 years.
The study concluded that family size had a major influence on the development of stomach cancer linked to the bacterium Helicobacter pylori (幽门螺杆菌), and that younger siblings (兄弟，姐妹，同胞，同属) from large families were especially prone to the most common form of stomach cancer.
H. pylori lives in the mucous (黏液的) layer of the stomach and is associated with peptic ulcers (消化器官溃疡) and stomach cancer. It’s estimated that half of the world’s population carries H. pylori in the stomach. It can be transmitted orally from person to person or through contact with human feces (粪便).
The study found that men who carried certain strains of H. pylori in their stomachs and had seven or more siblings had more than twice the risk of developing stomach cancer, compared to men with the same H. pylori strains who had one to three siblings.
A. Family size may determine stomach-cancer risk.
B. Family size may move stomach-cancer risk.
C. The study may follow more than 7,000 Japanese-American men for 28 years.
D. People from small families have an increased risk of stomach cancer.

[单项选择]Avoid the rush-hour’ must be the slogan of large cities the world over. If it is, it’s a slogan no one takes the least notice of. Twice a day, with predictable regularity, the pot boils over. Wherever you look it’s people, people, people. The trains which leave or arrive every few minutes are packed: an endless procession of human sardine tins. The streets are so crowded, there is hardly room to move on the pavements. The queues for buses reach staggering proportions. It takes ages for a bus to get to you because the traffic on the roads has virtually come to a standstill. Even when a bus does at last arrive, it’s so full, it can’t take any more passengers. This whole crazy system of commuting stretches man’s resources to the utmost. The smallest unforeseen event can bring about conditions of utter chaos. A power-cut, for instance, an exceptionally heavy snowfall or a minor derailment must always make city-dwellers realise how precarious the balance is. The extraordinary thing is not t

B. remove into the country
C. avoid rush hours and other disadvantages

Assuming that the engineering problems could be overcome, the production of a time machine could open up a Pandora’s box of causal paradoxes. Consider, for example, the time traveler who visits the past and murders his mother when she was a young girl. How do we make sense of this If the girl dies, she cannot become the time traveler’s mother. But if the time traveler was never born, he could not go back and murder his mother.
Paradoxes of this kind arise when the time traveler tries to change the past, which is obviously impossible. But that does not prevent someone from being a part of the past.
Suppose the time traveler goes back and rescues a young girl from murder, and this girls grows up to become his mother. The causal loop is now self-consistent and no longer paradoxical. Causal consistency might impose restrictions on what a time traveler is able to do, but it does not rule out time travel per second.
Even if time travel isn’t st
A. the time machine in the future would be feasible
B. the time machine in the future is just like the Pandora’s ox
C. the time machine in the future is still doubtful
D. the time machine in the future might cause murder
