Tears are nature's way of making us feel more...

Tears are nature's way of making us feel more comfortable. When our eyes is made uncomfortable by some small pieces of pollution, or when we are cutting onions, or when we are exhausted and “red –eyes” from over work and late hours, tears form in our eyes to clean and re-flesh them.

Tears are also a sign of strong emotion. We cry when we are sad and we cry when we are happy.

And tears seem to be uniquely（唯独）human. We know that animals also experience emotion—fear, pleasure, loneliness — but they do not shed （流） tears. From this, we can conclude that tears are closely related to the emotional and biological make up of the human species.

Biologically speaking, tears are actually drops of saline fluid, which is a little bit salty, produced by a gland（腺）in the body. Because salt is an important component, tears may actually constitute the most conclusive evidence that the human animal is the end product of a long evolutionary process that began in the sea.

And it is clear that, in addition to（除了） the emotional benefits（好处）, the shedding of tears has a specific biological function as well. Through tears, we can eliminate from our body certain chemicals which build up in response to stress and create a chemical imbalance in the body. Crying actually makes us feel better by correcting that imbalance and making us feel good again. And thus the emotional and the biological functions of tears merge（合并）into one and make us even more "human" than we would otherwise be.

68．According to the passage, human beings may have originated（起源于）in________.

A．the sea             B．the salt        C．chemicals      D．animals

69．Which of the following is NOT a function of tears?

A．Biological       B．Emotional    C．Political   D．Chemical

70．According to the article, which of the following is unique to humans?

A．The feeling of loneliness.         B．The state of feeling good.

C．The ability to shed tears          D．The feeling of fear

71．The underlined word “eliminate” probably means_______.

A．add            B．produce       C．replace        D．remove

Some people make you feel comfortable when they are around. You spend an hour with them and feel as if you have known them half your life. 1..

Here are several skills that good talkers have. If you follow the skills, they’ll help you put people at their ease, and make friends with them quickly.

First of all, good talkers ask questions. 2.　 . One well-known businesswoman says, “At business lunches, I always ask people what they did that morning. It’s a common question，but it will get things going.” From there you can move on to other matters—sometimes to really personal questions. 3.. Second, once good talkers have asked questions, they listen to the answers .This point seems clear, but it isn’t. Your questions should have a point and help to tell what sort of person you are talking to. And to find out, you really have to listen carefully and attentively.

4.　 . If someone sticks to one topic, you can take it as a fact that he’s really interested in it. Real listening also means not just listening to words, but to tones of voice. If the voice sounds dull, then, it’s time for you to change the subject.

Finally, good talkers know well how to deal with the occasion of parting. If you’re saying goodbye, you may give him a firm handshake and say, “I’ve really enjoyed meeting you.” 5.. Let people know what you feel, and they may walk away feeling as if they’ve known you half their life.

A. Real listening at least means some things.

B. You can become a popular person.

C. Almost anyone, no matter how shy he is, will answer a question.

D. And how he answers will let you know how far you can go.

E. If you want to see that person again, don’t keep it a secret.

F. It’s polite to listen to others with a smile.

G. These people have something in common.

Suppose you want to bring home a new cat and are looking for a way to really make it feel at home. Actually, all you need to do is buy some nice cat furniture and have it in place by the time you bring it into your home.

The first thing that you should prepare is a cat house. Two to three feet off the ground is the best height. If you don’t have enough room for a cat house, a cat bed is also a nice choice.

Once you have a nice spot where your cat can go to feel safe, then it’s time to get cat furniture that offers your pet a nice place to play. One nice choice is cat trees. Scratching posts (猫抓板) are another great idea if you are short in space, but still want to give your cat a nice place where it can claw (抓) at instead of your own furniture.

If you’re looking for a great way to shop for cat furniture, simply turn on your computer and do some online shopping. In no time will you be able to skim all the offerings from many online stores. What’s great is that you can easily compare products and their prices, so you can get what you want at the best possible price. And, probably the nicest thing about online shopping is that your purchases may be shipped right to you, so you don’t have to waste time making a trip to the store.

So, if you have brought a new cat into your home, make sure that home is an inviting one by buying some new cat furniture. Without it, your cat might feel lost and unsafe, which you definitely do not want to happen.

1.What should you do first before you bring a cat home?

2. According to the author, the first concern for a cat house is __________.

3.What is the best choice for your cat to play with if you have little room?

4.What is the author’s advice on shopping for cat furniture?

Many of us love July because it’s the month when nature’s berries and stone fruits are in abundance. These colourful and sweet jewels form British Columbia’s fields are little powerhouses of nutritional protection.

Of the common berries, strawberries are highest in vitamin C, although, because of their seeds, raspberries contain a little more protein (蛋白质), iron and zinc (not that fruits have much protein). Blueberries are particularly high in antioxidants (抗氧化物质). The yellow and orange stone fruits such as peaches are high in the carotenoids we turn into vitamin A and which are antioxidants. As for cherries (樱桃), they are so delicious who cares? However, they are rich in vitamin C.

When combined with berries of slices of other fruits, frozen bananas make an excellent base for thick, cooling fruit shakes and low fat “ice cream”. For this purpose, select ripe bananas for freezing as they are much sweeter. Remove the skin and place them in plastic bags or containers and freeze. If you like, a squeeze of fresh lemon juice on the bananas will prevent them turning brown. Frozen bananas will last several weeks, depending on their ripeness and the temperature of the freezer.

If you have a juicer, you can simply feed in frozen bananas and some berries or sliced fruit. Out comes a “soft-serve” creamy dessert, to be eaten right away. This makes a fun activity for a children’s party; they love feeding the fruit and frozen bananas into the top of the machine and watching the ice cream come out below.

1.Why is fresh lemon juice used in freezing bananas?

A. To make them smell better.　　 B. To keep their colour.

C. To speed up their ripening.　　 D. To improve their nutrition.

2.What is “a juicer” in the last paragraph?

A. A dessert.　　 B. A drink.

C. A container.　　 D. A machine.

3.From which is the text probably taken?

A. A biology textbook.　　 B. A health magazine.

C. A research paper.　　 D. A travel brochure.

4.What does the author seem to like about cherries?

A. They contain protein.　　 B. They are high in vitamin A.

C. They have a pleasant taste.　　 D. They are rich in antioxidants.

Free energy is everywhere around us. There are many ways to make and collect energy from various sources like sun, wind and water. People also realize that everyday stuff can be a source of energy too. For example, riding a bike, running or just walking, etc. We simply have to change our way of thinking if we want to change the world.

So comes the idea of solar roadways. Are they the road of future? Why use roads just for driving and collecting tolls (过路费)? Why don’t we use them for collecting energy?

The US Department of Transportation recently awarded $100,000 to Solar Roadways to build the first ever Solar Road Panel. So how do these future roads work?

The Solar Road Panels will contain embedded (嵌入的) LEDs which “paint” the road lines from beneath to provide safer nighttime driving as well as to give drivers instant instructions such as detour (绕行) ahead. The road will be able to sense wildlife on the road and can warn drivers to “slow down”. There will also be embedded heating elements in the surface to prevent snow and ice buildup, providing safer winter driving.

Replacing asphalt (沥青) roads and parking lots with Solar Roadway Panels will be a major step toward stopping climate change. Fully electric vehicles will be able to recharge along the roadway and in parking lots, finally making electric cars practical for long trips.

We just can’t wait to see more of these roads all over the world in the near future.

1.The first paragraph serves as a(n)______.

A. argument      B. comment       C. explanation      D. background

2.Which of the following is NOT true of LEDs?

A. They color the road lines.

B. They are embedded in the Solar Road Panels.

C. They are beneficial for nighttime driving.

D. They can provide instant instructions.

3. When some animals are on the solar road, what will the road do?

A. Guide them to a safer place.           B. Remind drivers to drive slowly.

C. Frighten them away from the road.      D. Advise drivers to choose another way.

4. From the text, we can know that the Solar Road Panels can______.

A. provide heat for drivers in winter

B. guide drivers who get lost on the highway

C. melt snow and ice soon in winter

D. help drivers see the road clearly in the sun
