The reason is simple．During the pioneering days, wet rice was laid out to dry along this road． 　　A few roads in Singapore are named by their shapes．There is “Circular Road” for one．Other roads may have part of their names to describe their shapes, like “Paya Lebar Crescent”．This road is called a crescent(月牙)because it begins on the main road, makes a crescent and comes back to join the main road again． (1) We learn from Paragraph 1 that ________． [　　] A． the government is usually the first to name a place B． many places tend to have more than one name C． a ceremony will be held when a place is named D． people prefer the place names given by the government (2) What does the underlined phrase “die hard” in Paragraph 1 probably mean?

[　　] A． Raffles Place． B． Selector Airbase． C． Piccadilly Circus． D． Paya Lebar Crescent． (4) Bras Basah Road is named ________． [　　] A． after a person B． after a place C． after an activity D． by its shape (5) What can be inferred from the passage? [　　] A． Some place names in Singapore are the same as in Britain． B． Some places in Singapore are named for military purposes． C． The way Singaporeans name their places is unique． D． Young Singaporeans have forgotten the pioneers．
