8．We all know that certain oils are healthier than others．but your oil health goes beyond just the type．The health of your oil can be related to how you use it too．
Each type of oil has what is called a"smoke point．"The smoke point is the specific temperature at which the oil starts to break down，or in more technical terms，its molecular structure begins to change．These molecular changes result in； changes in flavor，as well as changes in nutritional value，specifically，the nutritional value of the oil starts to reduce；changing what once may have been considered an especially healthy oil，like Olive，into one that is unhealthy．
The higher an oil's smoke point is，the higher the temperature of the oil can be．As a result，each type of oil should be used for the cooking method that is most appropriate to its individual smoke point and heat tolerance．Here is a quick guide for the next time you reach for your favorite oil．

Heat During Cooking	Oil	Best Use
Low to Moderate	Coconut	Baking （low heat ） Light Sauteing Pressure Cooking Salads
	Corn
	Olive
	Peanut
	Sesame
	Walnut
Medium Heat	Macadamia Nut	Baking Sauteing Stir-Frying
	Safflower
High Heat	Grape-seed	Deep Browning Deep-Frying
	Sunflower
	Soybean/Soy

Note that the above table represents oils that are refined（精炼的）．Most oils we buy are refined．Refined oils tend to have much higher smoke points than when they are unrefined．They also differ in nutrition and flavor．Unrefined oils are more nutritious and they tend to be much richer in flavor．
When it comes to extremely high heat cooking，always choose oils which are refined．

62．What determines whether an oil is healthy or not？D
A．Whether it's refined or not．
B．Its smoke point．
C．Its molecular．
D．How you use it．
63．Which of the following might be a better choice to make a healthy salad？C
A．Refined walnut oil．    B．Safflower oil．
C．Unrefined olive oil．   D．Sunflower oil．
64．Healthy oil can become unhealthy if．Baccording to the passage．
A．you keep it for too long
B．it is heated well beyond its smoke point
C．it is refined
D．its flavor is changed
65．The author wants to tell readers thatC．
A．oils are related to health
B．oils'value depends on their smoke points
C．"certain oils are healthier"is relative
D．oils'flavor and nutrition are connected．

5．See a cellphone cover that you like on Taobao？Forget about placing an order，paying the bill online and waiting for days for it to be delivered to you．In the near future，you'll be able to get it in minutes just by hitting"print"on your computer．You might find it hard to believe that you could actually"print"an object like you would a picture．But it is not that hard to understand how it would work．Just as a traditional printer sprays ink onto paper line by line，modern 3D printers spread material onto a surface layer by layer，from the bottom to the top，gradually building up a shape．Instead of ink，the materials the 3D printer uses are mainly plastic，resin and certain metals．The thinner each layer is-from a millimetre to less than the width of a hair-the smoother and finer the object will be．This may sound like a completely new technology，but the truth is that 3D printing has been around since the late 1980s．Back then，it was barely affordable for most people，so few knew about it．Last year，though，saw a big change in the 3D printing industry-printers became much cheaper．For example，10years ago a desktop 3D printer might have cost￡20，000，while now they cost only about￡1，000，according to the BBC．Taken out of the factory and introduced to more diverse and common uses，3D printing can create just about anything you can think of-flutes，bikinis，jewelry，aircraft parts and even human organs．In fact，scientists from Cornell University in New York have just made an artificial ear using a 3D printer，according to Science Daily．The fake ear looks and acts exactly like a natural one．However，as 3D printing becomes more common，it may bring about certain problems-such as piracy．"Once you can download a coffee maker，or print out a new set of kitchen utensils on your personal 3D printer，who will visit a retail store again？"an expert in 3D printing told Forbes News．Even more frightening，what if anyone in the world could use a 3D printer to print out a fully functioning gun？
8．According to the article，in the future，the 3D printing technology willB．
A．enable people to make better purchases online　
B．change the way we make many products　
C．be applied as widely in our daily life as computers　
D．shorten the time it takes for people to get what they buy online
9．What happened in the 3D printing industry last year？D
A．The 3D printing technology was taken out of the factory．
B．The 3D printing technology began to be used in various fields．
C．The 3D printer was used for medical treatment for the first time．
D．The 3D printer became more affordable for consumers．
10．How is the last paragraph developed？A
A．By giving examples．B．By making comparisons．
C．By analyzing the cause and effect．D．By presenting research findings．
11．What is the best title of the passage？D
A．Great Demand for 3D Printers　　
B．Technology in the Future
C．Online Shopping Disappearing　　
D．Printing out Everything．
