汽车防冻液

汽车在行驶时,发动机的温度会升得很高.为了确保安全,可用水循环进行冷却.实际上,水中往往还要

加入不易挥发的防冻液(原液),加入防冻液后的混合液冬天不容易凝固,长时间开车也不容易沸腾.

有关资料表明,防冻液与水按不同的比例混合,混合液的凝固点、沸点不同,具体数值参见下表(表中防冻液含量是指防冻液在混合液中所占体积的百分比):

在给汽车水箱中加防冻液时,宜使混合液的凝固点比本地常年最低气温低 10~15℃.考虑到混合液比热容的减小会影响散热效果,因此,混合液中防冻液的含量不宜过高.

(1)在混合液中,如果防冻液含量由30%逐渐增大到90%,则混合液凝固点的变化情况是            .(2分)

A.逐渐升高     B.逐渐降低

C.先升高后降低   D.先降低后升高

(2)若某地常年最低气温为-15℃,对该地区汽车来说,在下列不同防冻液含量的混合液中,宜选               .(3分)

A.30%       B.40%       C.60%      D.90%

(3)长时间使用后,汽车水箱中的混合液会减少.与原来相比,混合液的沸点      (2分,选填“升高”、“降低”或“不变”),其原因是                    .(3分)

BUILDING up a close bond (关系) with friends is important in all cultures. But different cultures have different ways of socializing.

The Chinese love going to restaurants. Family, friends and colleagues all go out to eat as a way of relaxing. So Chinese restaurants are much louder and noisier places compared with those in the Western world.

Although British people do socialize by going out for dinner, most people meet in pubs. They go there in the evening and sometimes during the day. Most people order wine or beer.

Going for a drink with colleagues after work is a particularly important British tradition. A recent survey of office workers found three-quarters of people regard the after-work drink as the key to building positive relationships with colleagues.

But for the French, the preferred place to socialize is in cafés. They are a central part of daily life in France and its culture. People will go to cafes at all times during the day.

In the morning, people may go there to buy a newspaper and a cup of coffee. At lunch they may go there for something to eat. Then when it's evening they may return to enjoy a glass of wine.

While the meeting place is different from culture to culture, "Essentially (本质上) they serve the same purpose, which is that humans need a place to come together to meet," said Aidan Saunders, a professor of social history at the University College London. "We are sociable animals."

People from different parts of the world have different values, and sometimes these values are quite against each other. However, if we can understand them better, a multicultural environment will offer a wonderful chance for us to learn from each other.
