Question

The bicycle is one of the simplest yet most useful inventions(發(fā)明)in the world．What is most surprising is that it was not invented earlier, although the great inventor Leonardo da Vinci had drawn pictures for bicycles and also for flying machines and some other things．Those things were not produced(生產(chǎn))until long after he died． 　　A person riding a bicycle uses little energy(能量)to make the bicycle move, and there is no pollution(污染)at all when you are riding．Even so, in developed countries, most people don’t travel to work by bicycle．It is not because the bicycles are expensive or people feel tired if they ride to work．It’s because the number of cars on the roads becomes larger．It certainly becomes more dangerous to ride a bicycle．As a result, more people put their bicycles away and go to work in their cars and, in this way, the situation(情形)is made more serious．Perhaps the best way to make riding safer and more popular is to create paths(開設(shè)通道)only for bicycles, and to make it so difficult and expensive for drivers to take their cars into the city that they will go back to using their bicycles． (1) Bicycles was invented ________． [　　] A． by Leonardo da Vinci B． long before Leonardo da Vinci died C． soon after Leonardo da Vinci died D． long after Leonardo da Vinci died (2) If you want to make the bicycle move, you need ________． [　　] A． ride as hard as you can B． no energy at all C． little energy D． quite a lot of energy (3) In developed countries, ________． [　　] A． not many people would like to ride bikes to work B． most people travel to work by bike C． bicycles are expensive D． people feel tired to ride to work (4) More people go to work by car because ________． [　　] A． their cars become larger B． the bike is dangerous C． they can’t afford to buy bicycles D． riding on the road is dangerous (5) Which of the following sentences is not right about how to make riding more popular?
