Believe it or not, have you ever noticed that you feel happier and more relaxed after you eat bread, pasta or fruit? Do you find that you are more energetic and awake after eating yogurt or beans? These things are not accidents. Food affect 1. we feel more than we think. Scientists researching 2. (it) effect on our moods are beginning to understand that we can influence our feelings with what we eat.
Although our moods relates 3. having various foods, it is not quite as simple as choosing the foods for the right occasions. If that 4. (be) the case, athletes would not eat a lot of carbohydrates before a race.
Another chemical 5. (connect) with our mood is caffeine, which 6. (find) in coffee, chocolate and many types of tea, is perhaps 7. worst thing you can have when you are feeling stressed.
Of course, 8. (enjoy) a nice meal with friends, whatever we eat, can also impact our spirits. Being with friends and family plays a big part in experiencing happiness.
Most 9. (important), though, remember the following old rule: try to eat different food, 10. not too much.

A good training partner can be a great asset(有用的人)to your training but if you get stuck with a bad one，it could lead you down the road to frustration. 1.Here are a few things to look out for： Dependable. Choose someone who you are sure will show up for every scheduled workout or who will call you if they can't make it. It is a drain(消耗) on your valuable energy especially before training to have to constantly remind your partner.
Attitude. Get a partner with a positive attitude. This is very important. If they constantly say that something impossible or that they can't or you can't do something，you may end up believing them. 2.
Open mind. Get a partner with an open mind. Someone who has to do things his or her way all the time，will not listen to you and will not change his or her mind isn't a good partner. 3.The leader should take into account the needs and feelings of the other partner not totally ignoring them.
Spotting. Get someone you feel comfortable with spotting you. One of the main roles of a training partner is spotting and if you don't trust them，there's not much point in having them around to help.
4.If you are a beginner，try to find someone who knows what they are doing. You will get more out of your training than if you train with another beginner.
While there are a number of advantages of having training partner，there are also advantages of working alone. 5.
A.Training level.
B.Similar strength levels.
C.Be selective when choosing a training partner.
D.Find someone with a similar training goal as you.
E.In every partnership，one person will tend to be the leader.
F.Do not train with someone who is satisfied with no improvement.
G.In the end，it is really up to you whether or not you need a training partner.
Over a hundred years ago in 1911, something strange was found in the glaciers of Antarctica. Grilffith Taylor—an Australian geologist, had discovered a blood red steam pouring out of the ice cascades（瀑布）of Talor Glacier! Popularly known as the Blood Falls, scientists had not been able to find the reason behind the blood red liquid flowing through the ice---until recently. The mystery of the Blood Falls had finally been solved.
When these falls were first discovered, scientists had believed that the red colour came from a large amount of red algae（海藻）concentrated in the water. Red algae contain a pigment（色素）which reflects red light, making the algae appear red.
This theory made sense, until it was later found that algae do not play a part in the red color of the flowing liquid at all. What really causes Talor Glacier’s waters appear blood red, is the presence of iron oxide in the liquid. The waters of the blood falls are rich in salt and iron content, and when this water comes in contact with the air, it turns red—just like rust! The water in these falls is often referred to as “brine” by scientists because of the high salt content in the water.
This reasoning behind the red colors of the falls was found back in 2003. However, the entire mystery had not yet been solved. How is it then, that the Blood Falls are not frozen?
Researchers at the University of Colorado and University of Alaska found that inside the glacier, there was a network of channels and reservoirs that move the water around. Salt water has a lower freezing temperature. In addition, when any substance undergoes a change in state, it gives off heat. Therefore, the brine actually warm itself up while it’s freezing! How this works, is that when the brine is flowing through the Talor Glacier, some of it does freeze. As a result of changing state from liquid to ice, the brine gives off heat. This heat is enough to keep the rest of the rest of the brine in liquid form, which is why it flows out of the glacier.

Bees play a vital role in the world. Unfortunately, bees are dying by the second.
The main purpose of bees is to make honey. Honey, shockingly, does not exist for human consumption, it is essential to the insects. Honeybees store honey in their hives (蜂巢) in order for the bees to have energy for their flight muscles and for heating the hive during the winter period. They collect pollen (花粉) which supplies protein for young bees to grow.
According to Honey, com, the increased production and quality of agricultural crops as a result of honey bee pollination is valued more than $14.6 billion per year. These insects are responsible for over 70 of the fruits and vegetables we eat today, including apples, grapes, coffee, beans, and broccoli.
So if they are so valuable to agriculture, why do they keep dying off? A key suspect seems to be pesticides (农药). Honeybees who are exposed to pesticides result in the damage to their neurological (神经的) functions, specifically memory or behavior. And that’s why the majority of worker bees disappear and leave behind a queen, plenty of food and a few nurse bees to care for the remaining immature bees and the queen. There are several other causes to the decline of bees, including the destruction of natural habitat, like woodlands, forests, and other habitats for bees. Climate change is also a factor in the decline of the wild bee population.
Actually, there are a variety of methods to help the bee population grow. One way is to start your own organic garden by planting bee-friendly plants. Pesticides are used in both industrial practices and even in your home, so it is best to find organic seeds and weed killers.
1.Why do honeybees store honey in their hives?
A.To provide enough honey for human to consume.
B.To draw protein out of honey for young bees.
C.To help attract other insects and make hives stronger.
D.To strengthen bee muscles and heat hives in winter.
2.Apples and beans are mentioned in the third paragraph to show that ________.
A.bees supply human beings with basic food
B.bees mainly live on these agricultural crops
C.bees are of great importance to fruits and vegetables
D.bees can bring in more money for famers every year
3.What is most likely to cause the worker bees to leave their hives behind?
A.The lack of food.
B.The abuse of pesticides.
C.The fighting among bees.
D.The destruction of the habitats.
4.What would the author probably discuss in the paragraph that follows?
A.Another way to save bees.
B.Other tips for choosing seeds.
C.More methods to plant green organic fruits.
D.Causes of the decline in the wild bee population.
For the last eight years, Jo Meade rode her bike each Sunday on a 16-mile round trip to her job washing dishes. It took more than an hour each way. Other days of the week she would spend two hours on three buses from her apartment to get to the other work, for a four-hour round trip.
That was the “before” part of her life. The “after” part of her life was started by the community Police Officer Trevor Arnold, who delivered a used car to her with the help of a car dealer and other donors.
Arnold, who spotted Meade, red and sweaty, riding her bike in the worst heat this summer, decided he would get her a car. He intended to quietly buy her a used car out of his own pocket so he turned to his friend Kody Slaght, a car salesman, to ask about a car priced $ 1,000. That wasn’t enough for a reliable ride, Slaght said, but the dealership said they would find a good car for her at a good price. Soon others were donating. Slaght and Arnold wouldn’t say how much the car cost, but the value is about $ 4,000.
Arnold said he was motivated by Meade’s work ethic (职业道德) to help. “I see a lot of hardworking people but that’s when they are at work. Can you imagine spending four hours of your day getting to and from work?” he said.
Meade’s boss said she was awesome and really reliable when she worked and she got along with others. “She’s willing to ride the three buses to get in here on her day off if we need her to.”
Meade said she was planning to buy a car, “but I haven’t been able to afford it,” she said. “Trevor, he is a very good guy. I did not expect this.”
1.What can we learn about Jo Meade’s work?
A.It’s free but low-paid. B.It’s time-consuming on the road.
C.It’s competitive and high-paid. D.It’s not worth her devotion.
2.Why did Slaght disagree to Arnold’s buying a car priced $ 1,000?
A.The car was not in good condition of driving.
B.The car was too expensive for Meade.
C.The car was beyond Arnold’s affordability.
D.The car had been donated to another person.
3.What inspired Arnold to buy a car for Meade?
A.Her devotion to work. B.His duty as a policeman.
C.His sympathy for Meade. D.Her desire for a better life.
4.What’s Meade’s feeling for the donated car?
A.Normal. B.Embarrassed.
C.Disappointed. D.Surprised.
