核心考点

举一反三
What are the limits (极限) of human body? The BBC"s Focus magazine has some answers.
How cold can you stand?
Normal body temperature is around 37℃. At 35℃ you"re unable to write your name. Even walking is very
difficult. At 33℃ you may find it difficult to think, understand and form (形成) opinions properly. By the time
you have cooled to 20℃, your heart would have stopped beating. Limit: 0℃. Ice would form in your tissues
(纤维组织), killing all the cells.
How spicy can you eat?
There is capsaicin (辣椒素) in many foods. The more capsaicin, the hotter the dishes are. If you"re healthy
enough, you can survive (存活) eating a teaspoon of pure capsaicin. But you would find it impossible to eat
anything else for a few hours. Limit: 5g capsaicin.
How fast can you run?
The fastest man in the world is Asafa Powell. The runner finished the 100m in 9. 74 seconds in 2007. This
gives an average (平均的) speed of 36. 96km/h. Top runners are at their fastest around 80 metres, so a runner"s
greatest speed may reach 43.06km/h. Limit: 43.06km/h.
How loud is too loud?
The loudest sound you can hear is 168 dB (分贝). Sound louder than that may do harm to your ears. The
loudest sound ever recorded was the eruption of Krakatoa (卡拉卡托火山爆发) in 1883. It was 180 dB, 160km
away.
Limit: 168 dB

a garden, and on the table is a piece of blue cardboard (硬纸版) with a drop of syrup (糖浆) on it. After a short
time, bees come to the syrup. The bees then fly to their hive (蜂房) and give the syrup to other bees in the
hive. Then they return to the feeding-place which they have found. After a while, the blue cardboard with the
syrup on it is taken away. Instead of this card, a blue card is now put on the left side of the first feeding-place
and a red card to its right. These new cards have no syrup on them. Very soon bees arrive again, and fly straight
to the blue card. None go to the red card.

of the world. The satellites take pictures of the atmosphere (大气), because this is where the weather forms
(形成). They send these pictures to the weather stations. So meteorologists (气象学家) can see the
weather of any part of the world. From the pictures, the scientists can often say how the weather will change.
Today, nearly five hundred weather stations in sixty countries receive satellite pictures. When they receive
new pictures, the meteorologists compare (比较) them with earlier ones. Perhaps they may find that the clouds
have changed during the last few hours. This may mean that the weather on the ground may soon change, too.
In their next weather forecast, the meteorologists can say this.
So the weather satellites are a great help to the meteorologists. Before satellites were invented, the scientists
could forecast the weather for about 24 or 48 hours. Now they can make good forecasts for three or five days.
Soon, perhaps, they may be able to forecast the weather for a week or more ahead (提前).

D. above space

C. the weather forms there
D. the pictures can forecast the weather
B. after they have compared new satellite pictures with earlier ones
C. before they received satellite pictures
D. during they study satellite pictures
B. two days
C. five days
D. seven days or even longer

heavy. The snow on the bottom pressed (挤压) together, it became ice.
The ice was very wide and thick. It began to move down the mountain. It was like a river of ice. It was a
glacier (冰河).
Sometimes the glacier moved only a few inches (英寸) each day. As it moved, it took rocks and dirt with it.
It changed the land. In some places, it left hills. In some places, when the glacier melted, it made rivers and
lakes.
A million years ago, there were many big glaciers. Glaciers covered many parts of the world. The glaciers
changed the land.
Glaciers are still at work today. A glacier in the north of Canada is cutting a new path (路) down the side of
a mountain. This glacier will change the land, too.
B. melted
C. became ice
D. turned to rain
