Expressions about water are almost as common as water itself. But many of the expressions using water have unpleasant meanings.
The expression “to be in hot water” is one of them. It is a very old expression. “Hot water” was used 500 years ago to mean being in trouble. One story says it got that meaning from the custom of throwing extremely hot water down on enemies attacking a castle．
That no longer happens. But we still get in “hot water”. When we are in “hot water”, we are in trouble. It can be any kind of trouble---serious or not so serious. A person who breaks a law can be in hot water with the police. A young boy can be in hot water with his mother if he walks in the house with dirty shoes．
Being in “deep water” is almost the same as being in hot water. When you are in deep water, you are in a difficult position. Imagine a person who cannot swim being thrown in water over his head. You are in deep water when you are facing a problem that you do not have the ability to solve. You can be in deep water, for example, if you invest in stocks without knowing anything about the stock market.
“To keep your head above water” is a colorful expression that means staying out of debt. A company seeks to keep its head above water during economic hard times. A man who loses his job tries to keep his head above water until he finds a new job．
“Water over the dam” is another expression about a past event. It is something that is finished. It cannot be changed. The expression comes from the idea that water that has flowed over a dam cannot be brought back again．
Another common expression, “to hold water”, is about the strength or weakness of an idea or opinion that you may be arguing about. It probably comes from a way of testing the condition of a container. If it can hold water, it is strong and has no holes in it. If your argument can hold water, it is strong and does not have any holes. If it does not hold water, then it is weak and not worth debating.
“Throwing cold water” also is an expression that deals with ideas or proposals. It means that one doesn’t like an idea. For example, you want to buy a new car because the old one has some problems. But your wife throws cold water on the idea because she says a new car costs too much.

Goldie's Secret
She turned up at the doorstep of my house in Cornwall. No way could I have sent her away. No way, not me anyway. Maybe someone had kicked her out of their car the night before. "We're moving house.'; "No space for her any more with the baby coming." "We never really wanted her, but what could we have done? She was a present." People find all sorts of excuses for abandoning an animal. And she was one of the most beautiful dogs I had ever seen.
I called her Goldie. If I had known what was going to happen I would have given her a more creative name. She was so unsettled during those first few days. She hardly ate anything and had such an air(样子) of sadness about her. There was nothing I could do to make her happy, it seemed. Heaven knows what had happened to her at her previous(以前的) owner's. But eventually at the end of the first week she calmed down. Always by my side, whether we were out on one of our long walks or sitting by the fire.
That's why it was such a shock when she pulled away from me one day when we were out for a walk. We were a long way from home, when she started barking and getting very restless（焦躁不安的）. Eventually I couldn't hold her any longer and she raced off down the road towards a farmhouse in the distance as fast as she could.
By the time I reached the farm I was very tired and upset with Goldie. But when I saw her licking (舔) the four puppies (幼犬) I started to feel sympathy towards them. "We didn't know what had happened to her," said the woman at the door. "I took her for a walk one day, soon after the puppies were born, and she just disappeared." "She must have tried to come back to them and got lost," added a boy from behind her. '
I must admit I do miss Goldie, but I've got Nugget now, and she looks just like her mother. And I've learnt a good lesson: not to judge people. How did the author feel about Goldie when Goldie came to the house?
| A．Shocked. | B．Sympathetic. |
| C．Annoyed. | D．Upset. |

Who hasn't found themselves reaching for the closest food available when they're tired and stressed? More and more research is proving that this isn't all in our mind. Some foods really do lead to a change in our moods (心情)．
Carbohydrate (碳水化合物) for calm
This is how some people medicate(治疗) themselves with food — by reaching for cookies or pasta(意大利面食) whenever they're upset. Unfortunately, it doesn't always work. You must eat a meal consisting of 100% carbohydrate, on an empty stomach, to obtain the serotonin (血清素) increase so that you have a good mood.
To get the wishedfor effect, you must not eat anything for four hours and then eat at least 30 grams of straight carbohydrate. Dry cereal (谷类食品), a piece of bread with jam, or a potato should do_the_trick.
Protein (蛋白质) for power
Of course, sometimes we don't need to be calm and sleepy.Sometimes we need a great deal of mental concentration, so this is when it's important to mix protein and carbohydrate. The protein will prevent the tryptophan (色氨酸) from flooding your brain，and the rise in serotonin(血清素) won't occur.
Why dessert makes us happy
Fat and sugar cause the brain to let go endorphins (内啡肽), which send pleasure signals throughout the body. This would be fine, except humans are not particularly good at stopping at one cookie or cake.
You can also satisfy your sweet tooth by choosing fruit for dessert.
Timing your meals for energy
Blood sugar drops after four hours of going without food, causing a decrease(减少) in energy. Eating usually fixes this within 20 to 30 minutes, but don't suppose that eating more will cause a faster increase in energy.
When you eat has as much of an effect on your mood as what you eat. If you regularly go for a long period of time between meals, rethink your schedule and plan ahead.The underlined phrase“ do_the_trick” in the third paragraph means ________.
| A．be extremely smart |
| B．intend to cheat someone |
| C．bring about the desired result |
| D．do something to amuse people |
The function of protein is ________.
| A．to help you keep calm and sleepy |
| B．to make you feel energetic |
| C．to lead you to slowness |
| D．to increase serotonin in your brain |
We can infer from the last two parts that ________.
| A．fat and sugar can greatly help people feel happy |
| B．we humans tend to eat lots of cookies and cakes |
| C．the more we eat, the faster we will gain energy |
| D．what we eat is more important than when we eat |
The main idea of the passage is ________.
| A．eating for a better mood |
| B．eating to make you calm |
| C．eating for more protein |
| D．eating to make us strong |
American researchers have discovered that human brains and sleep patterns are confused by devices(装置) that give out bright lights. Electronics, such as laptops, mislead our minds into thinking that it is still daytime, preventing sleep and increasing the risk of insomnia.
Sleep experts say human's natural body clock begins to rest and relax from the day between 9 and 10 pm but the use of computers confuses it.
A person's brain biologically becomes awake when the sun is out because bright light after dark causes the brain to stop producing the hormone (荷尔蒙) called melatonin that makes us sleepy.
Researchers say blue light from devices such as iPads, which is expected to become a popular reading tool when it comes out later this month, is particularly disruptive (干扰的)during the night when the brain thinks it should be dark.
Experts say a good book is a far better way of resting the brain and ensuring a good night's sleep because the bedside lamp(灯) light doesn't affect the brain as it does not look straight into a person's eyes.
“Potentially, yes, if you're using an iPad or a laptop close to bedtime... that light can be stimulating (刺激) to the brain to make it more awake and delay your ability to sleep，” Phyllis Zee, a professor at Northwestern University and director of the school's Centre for Sleep & Circadian Biology, told CNN.
“And I think more importantly, it could also be enough to affect your circadian (昼夜节律的) rhythm. This is the clock in your brain that determines when you sleep and when you wake up. ”
Alon Avidan, associate director of the Sleep Disorders Center at the University of California Los Angeles, added, “I wish people would just take a boring book — an oldfashioned book — and read by a lamp.”The underlined word “insomnia” in the first paragraph probably means “________”．
| A．being unable to eat properly |
| B．brain injury |
| C．being unable to fall sleep |
| D．lack of energy |
Melatonin is the hormone that ________.
| A．makes us sleepy |
| B．helps us relaxed |
| C．prevents us from waking up |
| D．makes us excited |
The bedside lamp light doesn't affect the brain because ________.
| A．it doesn't give out blue light |
| B．it's not as bright as your laptop |
| C．it doesn't enter your eyes directly |
| D．it is adjustable |
We can conclude from the passage that ________.
| A．one who uses his laptop often before bedtime can have his body clock disturbed |
| B．using a laptop before bedtime is more harmful than using an iPad |
| C．we'd better not do anything before going to bed |
| D．the best time to go to bed is before 9 pm |
Camping wild is a wonderful way to experience the natural world and, at its best, it makes little environmental influence. But with increasing numbers of people wanting to escape into the wilderness, it is becoming more and more important to camp unobtrusively (不引人注目地) and leave no mark.
Wild camping is not permitted in many places, particularly in crowded lowland Britain. Wherever you are, find out about organizations responsible for managing wild spaces, and contact them to find out their policy on camping and shelter building. For example, it is fine to camp wild in remote parts of Scotland, but in England you must ask the landowner’s permission, except in national parks.
Camping is about having relaxation, sleeping outdoors, experiencing bad weather, and making do without modern conveniences. A busy, fully equipped campsite(野营地) seems to go against this, so seek out smaller, more remote places with easy access to open spaces and perhaps beaches. Better still, find a campsite with no road access：walking in makes a real adventure.
Finding the right spot to camp is the first step to guaranteeing a good night’s sleep. Choose a campsite with privacy(隐秘) and minimum（最小的） influence on others and the environment. Try to use an area where people have obviously camped before rather than creating a new spot.
When camping in woodland, avoid standing dead trees, which may fall on a windy night. Avoid animal runs and caves, and possible homes of biting insects. Make sure you have most protection on the windward(迎风的) side. If you make a fire, do so downwind of your shelter. Always consider what influence you might have on the natural world. Avoid damaging plants. A good campsite found, not made—changing it should be unnecessary. You needn’t ask for permission when camping in________.
| A．national parks in England | B．most parts of Scotland |
| C．crowded lowland Britain | D．most parts of England |
The author thinks that a good campsite is one________.
| A．with easy access | B．used previously（以前） |
| C．with modern conveniences | D．far away from beaches |
The last paragraph mainly deals with________.
| A．protecting animals |
| B．building a campfire |
| C．camping in woodland |
| D．finding a campsite with privacy |
The passage is mainly about________.
| A．the protection of campsites |
| B．the importance of wild camping |
| C．the human influence on campsites |
| D．the dos and don’ts of wild camping |
It’s well known that our human memory can fail us. People can be forgetful, and they can sometimes also “remember” things incorrectly, with damaging consequences in the classroom, courtroom, and other areas of life. Now, researchers show for the first time that bumblebees(大黄蜂) can be unreliable witnesses too.
Bumblebees are rather clever animals, which explains why Chittka has been studying learning and memory in the insects for the last 20 years.
Most times when people have studied memory in animals, errors in performance have been taken to mean that the animals failed to learn the task or perhaps learned it and then forgot. But what if animals can experience a more interesting type of memory failure?
To find out, Chittka first trained bumblebees to expect a reward when visiting a yellow artificial flower followed by one with black-and-white rings. During subsequent tests, bees were given a choice between three types of flowers. Two were the types they’d seen in the training before. The third had yellow-and-white rings, representing a mixed-up version of the other two. Minutes after the training, the bees showed a clear preference for the flower that recently rewarded them.
One or three days later, however, something very different happened when the bumblebees’ memory was put to the test. At first, the bees showed the same preference displayed in the earlier tests, but as the time went on, they began selecting the flower with yellow rings, even though they’d never actually seen that one in training before.
Chittka says that insects make similar errors in the conjunction (结合) of long-term memories as humans do. The ability to extract (提取) common features between different events in the environment might come at the expense of remembering every detail correctly. In bees, with their limited brain capacity (容量), the pressure to store main features of several objects rather than each individual object might be much greater, compared with humans.Which of the following might be the best title of the passage?
| A．Human memory can fail sometimes. |
| B．Bumblebees make false memories too. |
| C．Humans are not as clever as bumblebees. |
| D．Bumblebees have extraordinary memory. |
Which of the following is the closest in meaning to the underlined word “subsequent”?
| A．scientific | B．accurate |
| C．following | D．exceptional |
According to the passage, which of the following statements is NOT true?
| A．Memory failure influences students’ study effects. |
| B．Bumblebees’ memory is complicated and worth studying. |
| C．The bees couldn’t make out which flower had rewarded them days later. |
| D．Bumblebees are stupid insects with limited brain capacity. |
What does the test mentioned in Paragraph 4 tell us?
| A．Short-term memories serve the bees well. |
| B．The yellow artificial flower appeals to the bees. |
| C．Bumblebees like the flowers with yellow-and-white rings. |
| D．Bees have remarkable abilities to distinguish colors. |
We can infer from the passage that ______.
| A．Chittka thinks that bumblebees failed to remember the color of the flowers |
| B．Researchers have learned that bumblebees are unreliable animals |
| C．There exist no similarities between the memory errors in humans and bees. |
| D．It is less challenging for humans than bees to store main features of several objects. |
