    Something in chocolate could be used to stop coughs and lead to more effective medicines,say UK researchers.

    Their study found that theobromine,found in cocoa,was nearly a third more effective in stopping coughs than codeine,which was considered the best cough medicine at present.

    The Imperial College London researchers who published their results online said the discovery could lead to more effective cough treatments.“While coughing is not necessarily harmful(有害的) it can have a major effect on the quality of life,and this discovery could be a huge step forward in treating this problem,”said Professor Peter Barnes.

    Ten healthy volunteers(志愿者) were given theobromine,codeine or a placebo,a pill that contains no medicine,during the experiment.Neither the volunteers nor the researchers knew who received which pill.The researchers then measured levels of capsaicin,which is used in research to cause coughing and as a sign of how well the medicines are stopping coughs.

    The team found that,when the volunteers were given theobromine,the capsaicin needed to produce a cough was around a third higher than in the placebo group.When they were given codeine they needed only slightly higher levels of capsaicin to cause a cough compared with the placebo.

    The researchers said that theobromine worked by keeping down a nerve activity(神经活动),which causes coughing.They also found that unlike some standard cough treatments,theobromine caused no side effects such as sleepiness.

    53.According to Professor Barnes,theobromine         .

    A.cannot be as effective as codeine

    B.can be harmful to people’s health

    C.cannot be separated from chocolate

    D.can be a more effective cure for coughs

    54.What was used in the experiment to cause coughing?

    A.Theobromine.              B.Codeine.                 C.Capsaicin.              D.Placebo.

    55.We learn from the text that volunteers in the experiment         .

    A.were patients with bad coughs

    B.were divided into three groups

    C.received standard treatments

    D.suffered little side effects

    56.Which of the following would be the best title for the text?

    A.Codeine:A New Medicine

    B.Chocolate May Cure Coughs

    C.Cough Treatment:A Hard Case

    D.Theobromine Can Cause Coughs

    答案  53.D  54.C  55.B  56.B

    The Queen’s English is now sounding less upper-class,a scientific study of the Queen’s Christmas broadcasts has found.Researchers have studied each of her messages to the Commonwealth countries since 1952 to find out the change in her pronunciation from the noble Upper Received to the Standard Received.

    Jonathan Harrington,a professor at Germany’s University of Munich,wanted to discover whether accent(口音) changes recorded over the past half century would take place within one person.“As far as I know,there just is nobody else for whom there is this sort of broadcast records,”he said.

    He said the noble way of pronouncing vowels(元音) had gradually lost ground as the noble upper-class accent over the past years.“Her accent sounds slightly less noble than it did 50 years ago.But these are very,very small and slow changes that we don’t notice from year to year.”

    “We may be able to relate it to changes in the social classes,”he told The Daily Telegraph,a British  newspaper.“In 1952 she would have been heard saying ‘thet men in the bleck het’.Now it would be ‘that man in the black hat’.Similarly,she would have spoken of ‘the citay’ and’dutay’,rather than ‘citee’and‘dutee’,and‘hame’rather than‘home’.In the 1950s she would have been ‘lorst’,but by the 1970s ‘lost’.”

    The Queen’s broadcast is a personal message to the Commonwealth countries.Each Christmas,the 10-minute broadcast is put on TV at 3 pm in Britain as many families are recovering from their traditional turkey lunch(传统火鸡午餐).

    The results were published(发表) in the Journal of Phonetics.

    45.The Queen’s broadcasts were chosen for the study mainly because         .

    A.she has been Queen for many years

    B.she has a less upper-class accent now

    C.her speeches are familiar to many people

    D.her speeches have been recorded for 50 years

    46.Which of the following is an example of a less noble accent in English?

    A.“Dutay”.          B.“Citee”.          C.“Hame”.         D.“Lorst”.

    47.We may infer from the text that the Journal of Phonetics is a magazine on         .

    A.speech sounds                                         B.Christmas customs

    C.TV broadcasting                               D.personal messages

    48.What is the text mainly about?

    A.The relationship between accents and social classes.

    B.The Queen’s Christmas speeches on TV.

    C.The changes in a person’s accent.

    D.The recent development of the English language.
