Tips for Cooking on a Tight Schedule
From my experience，there are three main reasons why people don't cook more often：ability，money，and time．1. Money is a topic I'll discuss another day．So today I want to give you some wisdom about how to make the most of the time you spend in the kitchen．Here are three tips for great cooking on a tight schedule：
1．Think ahead．The moments when I think cooking is a pain are when I'm already hungry and there's nothing ready to eat．So think ahead of the coming week．When will you have time to cook？Do you have the right materials already？2.
2．Make your time worth it．When you do find time to cook a meal，make the most of it and save yourself time later on．Are you making one loaf of bread？3. It takes around the same amount of time to make more of something．So save yourself the effort for a future meal．
3．4. This may surprise you，but one of the best tools for making cooking is to try new things．It gives you the chance to hit upon new ideas and recipes that can work well with your appetite and schedule．The more you learn and the more you try，the more ability you have to take control of your food and your schedule．
Hopefully that gives you a good start．5. And don't let a busy schedule discourage you from making some great changes in the way you eat and live!
A．Try new things．
B．Ability is easily improved．
C．Make three or four instead．
D．Understand your food better．
E．Cooking is a burden for many people．
F．Let cooking and living simply be a joy rather than a burden．
G．A little time planning ahead can save a lot of work later on．
Would it surprise you to learn that, like animals, trees communicate with each other and pass on their wealth to the next generation?
UBC Professor Simard explains how trees are much more complex than most of us ever imagined. Although Charles Darwin thought that trees are competing for survival of the fittest, Simard shows just how wrong he was. In fact, the opposite is true: trees survive through their co-operation and support, passing around necessary nutrition (营养) “depending on who needs it”.
Nitrogen (氮) and carbon are shared through miles of underground fungi (真菌) networks, making sure that all trees in the forest ecological system give and receive just the right amount to keep them all healthy. This hidden system works in a very similar way to the networks of neurons (神经元) in our brains, and when one tree is destroyed, it affects all.
Simard talks about “mother trees”, usually the largest and oldest plants on which all other trees depend. She explains how dying trees pass on the wealth to the next generation, transporting important minerals to young trees so they may continue to grow. When humans cut down “mother trees” with no awareness of these highly complex “tree societies” or the networks on which they feed, we are reducing the chances of survival for the whole forest.
“We didn't take any notice of it.” Simard says sadly. “Dying trees move nutrition into the young trees before dying, but we never give them chance.” If we could put across the message to the forestry industry, we could make a huge difference towards our environmental protection efforts for the future.
1.The underlined sentence “the opposite is true” in Paragraph 2 probably means ________.
A. trees compete for survival B. trees protect their own wealth
C. trees depend on each other D. trees provide support for dying trees
2.“Mother trees” are extremely important because they ________.
A. look the largest in size in the forest
B. pass on nutrition to young trees
C. seem more likely to be cut down by humans
D. know more about the complex“tree societies”
3.The underlined word “it” in the last paragraph refers to ________.
A. how “tree societies” work B. how trees grow old
C. how forestry industry develops D. how young trees survive
4.What would be the best title for the passage?
A. Old Trees Communicate Like Humans. B. Young Trees Are In Need Of Protection.
C. Trees Are More Complex Than You Think. D. Trees Contribute To Our Society.
We're surrounded by chemistry in everyday life. Sometimes it is easy to see, like when your science teacher conducts a big experiment in class. At other times, it can be extremely hard to see everyday chemistry at work, but nearly everything you touch or use has some element of chemistry in it.
Something as simple as toothpaste contains at least three chemicals, if not more. It is the mixture of them and its chemical reaction that keeps your teeth clean. Other things you use every day are created by chemistry, such as hair products, shampoo and soap. Adding detergent (洗涤剂) to water involves chemistry. Without chemistry, we would never have realized that we need soap to get the oil out of clothes or skin.
Chemistry not only helps us make products for use, but it also helps us understand the world around us. Chemistry helps us understand what the ozone layer (臭氧层) is and how it protects us. Chemistry also gives us sunscreen to protect us from the sun. Thanks to chemistry, we know bleach (漂白剂) can't be mixed with vinegar, because it can produce poisonous gas. Without chemistry, we wouldn't have had fireworks displays on important days like the Spring Festival.
Chemistry plays a big role in food preparation. Cooking food causes it to go through a chemical change. That is why cooked food often tastes different from raw (生的) food. Baking is a great example of chemistry. Too much or too little of any ingredient makes a difference to the result of baking, for example, the dough (面团) won't rise or the cake will be flat.
Chemistry isn't something that just lives in a lab; it's something that you come across hundreds of times every day. If you know how chemistry works, you will get a greater comprehension of the science behind some of the simplestlooking things.
1.What's the main idea of Paragraph 1?
A. Chemistry is easy to see around us.
B. Sometimes chemistry is hard to see around us.

D. Few things in everyday life contain chemistry.
2.The following actions are about chemistry EXCEPT ________.
A. cleaning teeth with toothpaste B. washing hair with hair products
C. using soap to remove the oil from clothes D. washing your face with water
3.The underlined word “poisonous” in Paragraph 3 means ________.
A. harmful B. healthy C. fresh D. pleasant
4.Which one is TRUE according to Paragraph 4?
A. One can't find chemistry when cooking food.
B. Chemistry plays an important part in food making.
C. That dough rises is nothing to do with chemistry.
D. A flat cake is the result of too many ingredients.
