Not long age, experiments showed that birds rely on the sun to guide them during daylight hours. But what about birds that fly by night？ Tests with artificial stars have proved that certain night - flying birds are able to follow the stars in their long - distance flights.
A dove (鸽子) had spent its lifetime in a cage and had never flown under a natural sky. Yet it showed an inborn ability to use the stars for guidance. The bird's cage was placed under an artificial star - filled sky. (76) The bird tried to fly in the same direction as that taken by his outdoor cousins. Any change in the position of the artificial stars caused a change in the direction of his flight.
(77) But the stars are apparently their principal means of navigation (航行) only. When the stars are hidden by clouds, they seemingly find their way by such landmarks as mountain ranges, coast lines, and river courses. But when it's too dark to see these, the doves circle helplessly, unable to find their way.
The reason why birds don't get lost on long flights ______.
A．have been known to scientists for many years
B．have only recently been discovered
C．are known by us
D．will probably remain a mystery

Before we left,I 33 Mr. Schwartz a 'present, a briefcase with his name on the front. I didn't want to forget him. 34 I didn't want him to forget me.

根据以下内容回答题：
A volcanic eruption in Iceland has sent ash across northern Europe．Airlines have stopped or changed the flights across the Atlantic Ocean，leaving hundreds of passengers stuck in air-ports．
Grimsvoto is oDe of the largest and most active volcanoes in Europe．What makes Grimsvoto different is that it lies under a huge glacier(冰川)of ice up to 12 meters thick．The hot volcano heats up the ice above it，which then forms a layer of water between the glacier and the volcano．This layer of water puts pressure on the volcano，keeping it stable．As the water flows out from under the glacier，the pressure lifts．The lava(岩浆)from the volcano then comes up to the surface．This is exactly what happened today．
Now．airlines have to make changes to their flights SO as not to fly through the clouds of volcanic as．h．According to．KLM，one of Europe’s biggest airlines，airplanes cannot go under the cloud or over it．Going through the cloud can result in ash getting stuck in the airplane’s engines，causing damage to the plane．
The eruption has also caused problems for animals in Iceland．The volcano left ash and sharp，glass-like rocks all over the countryside．Farmers are keeping their animals inside to stop them from eating ash—covered grass or the sharp objects．
What makes Grimsvoto different from other volcanoes？ 查看材料
A.It is below-ice．
B.It lies under the sea．
C.It is the largest volcano．
D.Its lava affects the airlines．
