第4题：
Have you ever served the auxiliary engine to combustion heavy oil? What should be borne in mind when transferring oil; from heavy oil to light oil?
正确答案：I have ever served the auxiliary engine to combustion a combination of A and C oil. When transferring oil from heavy oil to light oil, the changing of temperature should not be rapid. 1℃ to 2℃ per minute is the best. Meanwhile the viscosity changing is invariably observed. The oil temperature to be heated varies in quality of fuel oil. In general, 180 CST needs to be heated to 95-105℃; 380 CST needs to be heated to 130-135℃. The viscosity is under the control of approximately 2 Englers.

第8题：
单选题Advertisement: The most flavorful olives in the world are kalamata olives. The more kalamata olives used to make a bottle of olive oil, the more flavorful the oil, and no company buys more kalamata olives than Zorba’s Olive Oil. Therefore, when you buy Zorba’s Olive Oil, you’re buying the most flavorful olive oil available today. The reasoning presented in the advertisement is flawed because it overlooks the possibility that:ANot all of Zorba’s competitors use kalamata olives in their oil.
BZorba’s sells more olive oil than any other company.
CThe most flavorful olive oil is not necessarily the best olive oil.
DBecause of bulk discounts, Zorba’s pays less per kilogram of kalamata olives than does its competitors.
EThe number of kalamata olives harvested every year is far less than the number of Spanish olives harvested every year.

第13题：
（B）
The surprising experiment I am about to describe proves that air is all around you and that it proves down upon you. Air pressure is a wonderful force. When you swim underwater, you can feel water push down your body. The air all around you does the same. However, your body is so used to it that you do not notice this. The pressure is caused by a layer of air called the atmosphere. This layer surrounds the Earth, extending to about five kilometers above the Earth’s surface.
The following experiment is an easy one that you can do at home. But make sure that you are supervised, because you will need to use matches. Now foe the experiment！
What you need
?A hard-boiled egg without the shell
?A bottle with a neck slightly smaller than the egg
?A piece of paper
?A match
Metheod
1） Check that the paper will sit firmly on the neck of the bottle.
2） Tear the paper into strips and put the strips into the bottle.
3） Light the paper by dropping a burning match into the bottle.
4） Quickly sit the egg on the neck of the bottle.
Result
Astonishingly, the egg will be sucked into the bottle. Your friends will be amazed when you show them the experiment. But be careful when you handle matches.
Why it happened
As the paper burns, it needs oxygen and uses up the oxygen （air） in the bottle. The egg acts as a seal in the neck of the bottle, so no more air can get inside. This reduces the air pressure inside the bottle. The air pressure must equalize, so more air from outside must enter the bottle. The outside air pressure against the egg and then the egg is pushed into the bottle! The proves that air is all around and that it is pressing down on it.
60. Why is there the need to take care when you are doing the experiment?
A. The bottle could break.
B. You need to light the paper with a match.
C. The egg needs to be shelled.
D. The egg has to be perfectly placed on the neck of the bottle.
