阅读理解。阅读下列短文, 从给的四个选项 (A、B、C和D) 中, 选出最佳选项。 【2014·江西高安中学模拟】

Mouth bacteria grow fast in airless conditions.Oxygen rich saliva (唾液) keeps their numbers down.When we sleep，for example，the saliva stream slows，and sulfur (硫) producing bacteria gains the upper hand，producing classic “morning breath”．

Alcohol drinking，too much talking，breathing through the mouth during exercise，anything that dries the mouth produces bad breath.So can stress，though it’s not understood why.Some people’s breath turns sour every time they go on a job interview.

Saliva flow gradually slows with age，which explains why the elderly have more bad breath trouble than younger people do.Babies.however，who make plenty of saliva and whose mouths contain relatively few bacteria have characteristically sweet breath.

For most of us，the simple，dry mouth variety of bad breath is easily cured.Eating or drinking starts saliva and sweeps away many of the bacteria.Breakfast often stops morning breath.

Those with constant dry mouth find that it helps to keep gum，hard candy，or a bottle of water or juice around.Brushing the teeth wipes out dry mouth bad breath because it clears away many of the offending bacteria.

Surprisingly，one thing that rarely works is mouthwash.The liquid can mask bad breath smell with its own smell，but the effect lasts no more than an hour.Some mouthwashes claim to kill the bacteria responsible for bad breath.The trouble is，they don’t necessarily reach all offending germs.Most bacteria are well protected from mouthwash under thick layers of mucus (粘液)．If the mouthwash contains alcohol—as most do—it can worsen the problem by drying our mouth.

1．Which of the following is right?

A．Saliva flow gradually increases with age. B．Alcohol drinking does good to bad breath. C．Mouthwash is not an effective way to bad breath. D．Mouth bacteria can’t grow fast in airless conditions.

3．According to the passage，alcohol has something to do with bad breath mainly because________. A．it keeps offending bacteria from reproducing B．its smell adds to bad breath C．it kills some helpful bacteria

4．Mouthwashes are not an effective cure for bad breath mainly because________. A．they can’t mask the bad odor long enough B．they can’t get to all the offending bacteria

C．their strong smell mixes with bad breath and makes it worse D．they can’t cover the thick layers of mucus 5．We can infer from this passage that________. A．offensive breath can’t easily be cured B．elderly people are less offended by bad breath C．heavy drinkers are less affected by bad breath D．offensive breath is less affected by alcohol

Human remains of ancient settlements will be reburied and lost to science under a law that threatens research into the history of humans in Britain, a group of leading archaeologists (考古学家) says. In a letter addressed to the justice secretary, Ken Clarke, 40 archaeologists write of their “deep and widespread concern” about the issue. It centres on the law introduced by the Ministry of Justice in 2008 which requires all human remains unearthed in England and Wales to be reburied within two years, regardless of their age. The decision means scientists have too little time to study bones and other human remains of national and cultural significance.

“Your current requirement that all archaeologically unearthed human remains should be reburied, whether after a standard period of two years of further special extension, is contrary to basic principles of archaeological and scientific research and of museum practice,” they write.

The law applies to any pieces of bone uncovered at around 400 dig sites, including the remains of 60 or so bodies found at Stonehenge in 2008 that date back to 3, 000 BC. Archaeologists have been granted a temporary extension to give them more time, but eventually the bones will have to be returned to the ground.

The arrangements may result in the waste of future discoveries at sites such as Happisburgh in Norfolk, where digging is continuing after the discovery of stone tools made by early humans 950, 000 years ago. If human remains were found at Happisburgh, they would be the oldest in northern Europe and the first indication of what this species was. Under the current practice of the law those remains would have to be reburied and effectively destroyed.

Before 2008, guidelines allowed for the proper preservation and study of bones of sufficient age
