テスト勉強に必要な英語の訳がわかりません。
長文で量が多いですが、ご協力お願いします。
*plastic
Plastics are produced from a variety of raw materials: wood, coal, petroleum, plants,vegetable juices, and proteins.
In some respects, they are superior to comparable natural products because they are produced under scientifically controlled conditions and can be given specific properties not found in nature.
*telescope
The telescope had two major effects on astronomical observations: First, it allowed astronomers to see celestial objects with greater magnification. Second, it improved light-gathering power so that astronomers could see faint objects. In other word, astronomers using a telescope could see objects that are too small to be seen with the naked eye.
*refrigerator
In a refrigerator, the refrigerant, which is under low pressure, is evaporated in the evaporator. The latter is a coiled pipe mounted in the freezer compartment. The evaporation leads to a drop in temperature in the freezer compartment. A small compressor draws away the vapor, compresses it, and passes it to a condenser, where heat is given off.
*black hole
Any light emitted from the surface of the star is dragged back by the star's gravitational attraction before it can get very far. Many stars cannot be seen because the light from them does not reach us, and such objects are what we now call black holes.
*airline
Many airline routes have stages of less than one thousand, five hundred kilometers and smaller jet airliners have been designed
specifically for such "short-haul" operations. These aircraft are nearly as fast as the larger jet airliners, but carry only about eighty passengers. The engines are sometimes located beneath a high tail plane. This reduces noise in the passenger cabin. Short-haul airliners should be able to take off from relatively short runways and to permit rapid turn around(i.e. servicing, refueling and exchange of passengers between flights.)
