This was especially true for vacuum cleaners in the UK, because the popularity of carpets means sweeping is not an easy or effective means of carpet cleaning. In 1952, Hoover made the Constellation available to the public for the first time. Hoover designed it so that people could place the vacuum cleaner in the centre of the room and then work around it. After about 20 years of selling these vacuum cleaners in the UK, Hoover stopped the Constellation in 1975. Advances to upright and cylinder(氣缸） vacuum cleaners in the UK continued, enabling vacuum cleaners to bee more efficient and effective. The 1990s saw the introduction of the first bagless domestic vacuum cleaners in the UK. Despite many industry fears consumers would not be prepared to pay the high price, bagless vacuum cleaners became a big success in the UK. As for the future, vacuum cleaners in the UK are expected to bee even more energyefficient. can be inferred from the first paragraph? entered the UK vacuum cleaner market before the 1900s. ?s vacuum cleaners were more advanced than booth?s. ?s vacuum cleaners were very popular in the UK market. cleaners were invented later in the UK than in America. was the cloth bag on the earliest domestic vacuum cleaners used for? the vacuum cleaners. the vacuum cleaners more efficient. the vacuum cleaners. dust. was the most remarkable characteristic of the Constellation? was only used by the upper class. design allowed the user to work around it. was upright and it had a cylinder added to it. price was extremely high at the time. can learn form the passage that bagless vacuum cleaners . so popular that they could fulfill all UK customers? demands the most energyefficient vacuum cleaners. not accepted by UK customers expensive when they made their first public appearance in the UK D Cancer patients could increase their chance of survival and help stop their cancer spreading by survival and help stop their cancer spreading by taking aspiring, new research suggests. A daily pill was found to increase the chance of surviving cancer by 20 percent. Scientists at Cardiff University made the discovery after analysing a wealth of available date from studies of some cancers. They found that patients who took lowdose aspirin in addition to their usual treatment reduced their likelihood of dying, or the cancer spreading, by one fifth over five years. “There is a growing body of evidence that taking aspirin is of significant benefit in reducing some cancers,” said Professor Peter Elwood, from the University of Cardiff, who led the research. “while we know a low dose of aspirin has been shown to reduce the possibility of catching cancer, its role in the treatment of cancer remains uncertain. As a result, we set out to conduct a search of all the scientific literature.” The team collected date from five trials and 42 studies. Although a known risk associated with taking aspirin regularly is bleeding in the gut(腸子 ), the researchers found no evidence of this being serious or lifethreatening. Researchers say the study highlights the need for trials to show if aspirin should be remended alongside current cancer treatments. Professor Elwood added: “ While there is a desperate need for more detailed research to prove our review and to obtain evidence on less mon cancers,we?d urge patients diagnosed with cancer to speak to their doctor about our findings so they can make an informed decision as to whether or not they should take a low dose of aspirin as part of their cancer treatment.” Baroness Delyth Man, Chief Executive at Breast Cancer Now, said: “This study adds significant weight to the idea that a drug as simple and cheap as aspirin could help treat breast and other cancers. “ Clinical trials are going on to confirm whether aspirin could be added to routine treatments for breast cancer. Further research is needed to understand exactly which patients would benefi
