听力原文： In our lab today, we'll be testing the hypothesis that babies can count as early as five months of age. The six babies here are all less than six months old. You'll be watching them on closed-circuit TV and measuring their responses.

The experiment is based on the well-established observation that babies stare longer if they don't see what they expect to see. First, we're going to let two dolls move slowly in front of the babies. The babies will see the two dolls disappear behind a screen. Your job is to record, in seconds, how long the babies stare at the dolls when the screen is removed.

In the next stage, two dolls will again move in front of the babies and disappear. But then a third doll will follow. When the screen is removed, the babies will only see two dolls. If we're right, the babies will now stare longer because they expect three dolls but only see two.

It seems remarkable to think that such young children can count. My own research has convinced me that they have this ability from birth. But whether they do or not, perhaps we should raise another question -- should we take advantage of this ability by teaching children mathematics at such a young age? They have great untapped potential, but is it good for parents to pressure young children?

What's the experiment designed to demonstrate?

A．That babies understand language before they can speak.

B．That babies have simple mathematical skills.

C．Babies' preferences for different kinds of toys.

D．The influence of television on babies.

It's interesting that the arrival of snow has the effect on people in different countries. For some countries it is an important happening to celebrate each year, while for oth-ers a catastrophe (灾害) or even a wonder.

But there are countries between these two kinds that normally expect snow some time over the winter months, but never receive snow regularly or in the same quantities every year. Britain is one of them, for which the arrival of snow quite simply creates problems. Within hours of the first snowfalls, however light, roads are blocked; trains and buses have to stop in the middle of the way. Normal communications are affected as well: tele-phone calls become difficult and the post immediately takes more time than usual. And al-most within hours there are also certain shortages-bread, vegetables and other things-not because all these things can no longer be produced or sent to shops, but mainly be-cause people are frightened and go out and store up with food and so on… just for fear that something bad should happen.

But why does snow have this effect? After all, the Swiss, the Austrians and the Cana-dians don't have such problems. It is simply because there is not enough planning and preparation. We need money to buy equipment to deal with snow and ice. To keep the roads clear, for example, requires snow-ploughs (扫雪机) and machines to spread salt. The reason why a country like Britain does not buy snow-ploughs is that they are only used for a few days in any one year, and the money could be more useful in other things such as hospitals, education, helping the old, and so on.

According to the writer, Britain is a country ______.

A．which has regular snow

B．which is not well prepared for snow

C．for which snow is a catastrophe

D．for which snow is a wonder
