Wide，smooth，straight roads must be built now in place of the old and narrow roads. These roads must not pass through towns and cities. They must not be crossed by other roads.

Today such roads are being built in many countries in the world. These roads have at least two lanes，one for slow-moving traffic and the other for fast-moving traffic.

These roads do not pass through towns and cities；horses and bikes are not allowed on them. Accidents do not usually happen. Cars can travel hundreds of miles without having to stop.

But these modern roads often cannot be built in towns and cities. Before a road in a town can be made wide，many buildings have to be pulled down.

Some people feel that more car-parks should be built outside a city. Then the drivers should leave their cars and catch a bus or take a taxi to their offices.

 For years scientists have been arguing about whether nature or nurture (后天) decides what people will be like. Is it nature— what people are (41) with— that decides what they will be like? (42) is it nurture —what(43) to people when they are born —that decides what they will be like?

    Scientists have been studying twins to (44) if they can find the answer, because twins start out with the (45) DNA. Sometimes twins don’t live together at birth and grow up in different (46) and different places— so the nature is the same for both, but the nurture is different.

    When scientists (47) these twins in their later life, they some times find some surprising (48).

    Jim Springer and Jim Lewis were adopted（收养）by two different families at birth. They first met each other again thirty-nine years (49) and discovered they had a lot in (50). Both had been (51) twice. Their first wives were both named Linda and their second wives were both named Betty!

    Each twin had a son — one called his son James Alan and the (52) called his son James Alan, too. Their children each had a dog called “Toy”. They even arrived at their first (53) in the same color of car.

    So far twin (54) seem to show that both nature and nurture are important. What we have from birth, and how and where we live help to build (55) we are.
