But it is all of those Londons, an accrual of different descriptions and eras.It is a city made for description-reread the first passages of "Bleak House, " also on the subject of fog, for a moody introduction-and one that sorespects its authors that it buried a number of the best ones in style, in Westminster Abbey.     There are plenty of organized literarythemed tours around the city, easily found on the Internet.Or youcan wander characteristically on your own, which is more fun.If you take the Tube or the bus, make sure to carry a book.1．What can we infer from the first paragraph?A．Most people of London like visiting museums.B．No Londoners go to cinemas to see the films.C．A majority of Londoners are book lovers.D．All the Londoners like to walk in the rain.2．What information can you get from Pepy's diaries?A．Great Fire of 1666 caused by an accident in a bakery.B．Sherlock Holmes once lived in Baker Street.C．London Bridge is next to Baker Street.D．"Our Mutual Friend" is one of Dickens's works.3．Who is Sherlock Holmes?A．A book lover.B．A character of Dickens's novel: "Our Mutual Friend"．C．A detective.D．A person who set the Great Fire of 1666.4．In which book can't you find the description about the fog in London?A．"The Tiger in the Smoke"     B．"Sense and Sensibility"C．"Money"                  D．"Our Mutual Friend" 5．Which of the following statements is NOT true according to the passage?A．Most kinds of tours around London may be found on the Internet.B．You must be shown around London by a guide.C．There are many kinds of literarythemed activities including tours.D．You'd better take a book when you travel in London.
