2. I love online shopping, but for years I did all my shopping offline since I wasn’t sure if it is really safe to buy online. In the last few years I started buying almost everything online after I understood that buying online can be safer than buying offline as long as you follow a few safety rules.

★ Check for delivery times—If you need your product on a certain time—you’ll have to make sure if the site you are referring to is committed to your schedule.

★ Compare prices before you buy—There are many comparison sites and tools (such as Price Gong) that compare prices—this can save you a lot of money.

★ Don’t leave the computer unsupervised while shopping online—You don’t want that someone else will touch anything by mistake and will make the purchase.

★ Make sure you can contact the store if something goes wrong—You want to make sure that you will have someone to talk with if something goes wrong.

★ Always print out your order details and confirmation—Just in case that you’d need to contact the site, it is always better to give them detailed information about your order.

★ Make sure you buy from a well-known merchant—or check how others rated this merchant, there are some rubbish sites and you don’t want to buy from them.

★ If you use PriceGong—use the merchant ratings, product ratings and product description to know that you are buying the right product at the right store.

3. Going for walks with my two-year-old son, I meet many nice people who ask what my job is. When I say that I teach at Swarthmore College, their faces light up, and the next question is, “What do you teach?” As they hear my answer “linguistics (the scientific study of language)”, they look confused. The smile on their faces tells me that they don't know what to make of my answer. If they are brave enough, they will ask, “So, what kinds of classes do you teach then?” Good question.

I have long been teaching pragmatics (语用学), a branch of linguistics. It is primarily concerned with how the context (上下文) in which a sentence is said influences its meaning. What “I'd love a glass of water” means largely depends on where and when it is said. In a

restaurant, it will probably be understood as a request directed toward the waiter. Somewhere out in a desert, however, the same sentence is more likely to be interpreted as an impossible wish.

Thus, although the literal (照字面本义的) meanings of two sentences could be exactly the same, their communicative meanings could be very different.

Interestingly, in pragmatics you will discover a message can be well communicated though not literally expressed. This takes place when the speaker and the listener share common ground. If you see a car stopped on the side of the road, and you have the following exchange with the driver, you both know you've said enough to get your points across: Driver: Hi. I ran out of gas.

You: There's a Shell just down the road.

Obviously, the driver is really asking something like, “Could you tell me what to do?” Your reply implies that there is a place nearby where the driver can get gas. No further explanation is needed because Shell, the name of a gas station, is part of their common ground. 1.What do we know about the people in Paragraph 1? A.They are familiar with the author. B.They work at Swarth more College. C.They know little about linguistics. D.They hope to attend the author's class.

2.Why does the author say the underlined sentence has different communicative meanings? A.Because their speakers are different.

B.Because their literal meanings are different. C.Because their wishes are different. D.Because their contexts are different.

3.Why did the car mentioned in the text stop? A.To buy some gas. B.To ask for help.

C.To wait for someone. D.To take a short rest.

4.How does the author mainly explain pragmatics? A.By analyzing major causes. B.By making comparisons. C.By using examples.

D.By presenting research findings.

4. Patients in the early stages of Alzheimer’s disease often struggle to remember recently learned information, meaning they forget things like important appointments or where they left their keys. But it seems that these memories are not lost. They are still filed away in the brain somewhere; they just can’t be easily accessed.

Now, researchers at MIT have developed a means of getting back memories in mice suffering from Alzheimer’s. The method relies on a technique that uses light to control genetically modified neurons (转基因神经元). Currently it is too early to be used in human trials as it involves inserting light emitting (发光) equipment into the subjects’ brains, but the same principles still apply, the researchers said.

“The important point is that this is evidence of the concept. That is, even if a memory seems to be gone, it is still there. It’s a matter of how to get it back,” said the senior researcher Susumu Tonegawa.

The team took two groups of mice, one genetically engineered to develop Alzheimer’s and one healthy. They then placed them into a room and gave them a mild electric shock. All of the mice showed fear when put back in an hour later. When placed in the room a third time several days later, the Alzheimer’s mice acted normally. They had forgotten the shock.

The researchers were then able to bring back the memory of the shock by activating (激活) the cells in which the memories were stored. Even when the mice were put into an unfamiliar room, they showed fear when the cells associated with the shock were activated.

“Short­term memories seem to be normal in order of hours. But for long­term memories, these early­Alzheimer’s mice seem to be damaged,” said the lead researcher

Dheeraj Roy. “Directly activating the cells that we believe are holding the memory helps them get it back. This suggests that it is indeed an access problem to the information, not that they are unable to learn or store this memory.”

1.What can we learn about the researchers at MIT?

A.They can get back memories in mice with Alzheimer’s. B.They can cure Alzheimer’s using the new method. C.They are the pioneers of brain research. D.They have used the method in human trials.

2.Why did the Alzheimer’s mice behave normally the third time? A.They were accustomed to the situation. B.They managed to overcome the fear.

C.They failed to remember the electric shock. D.They activated the association automatically.

3.For long-term memories, the early-Alzheimer’s mice ________. A.can’t learn new tricks well B.can transform their brain cells C.can’t access the information stored D.can easily get back their memories 4.What’s the main purpose of the text? A.To introduce a method of a research.

B.To explain how a brain stores information. C.To give advice on how to improve memories. D.To report the latest discovery about a disease. 二、七选五

5. Here are some easy steps to create better habits that will surely improve your mental health. Get enough sleep. Keeping a consistent sleep schedule will ensure that your body and mind will function properly. Experts recommend that each person should sleep for at least 6.5 to 8 hours a night. ①__________When you restart, it refreshes everything and helps your machine function faster and better.

Do some exercise. You should know that regular exercise is necessary for a healthy body and soul. Some workout motivation tips from experts are that you should determine what exercises interest you and work your way up from there. Still no idea how to start?②__________

Mind what you eat. ③ __________You know your body and you also know potato chips have done nothing except make you feel sluggish and guilty. Do your heart and waistline a favor by feeding your body healthy things like lean protein, whole grains and fiber.

④__________Use journaling as a way to release tension you may be holding in. You can also use it as a way to organize your thoughts, transfer the chaos from head to paper. You don’t necessarily have to write for an audience. In fact, writing for yourself can be regarded as self-treatment and help you become more aware of yourself and your own thoughts.

Explore the world. You don’t need your passport for this one.⑤ __________No matter how old you are, there are many things in this life that you have yet to experience. Get out of your

comfort zone and see what the world has to offer you. You may actually be pleasantly surprised to try things you have never done before and how enjoyable they are. A. Start writing. B. Balance yourself.

C. Put down the hamburger and accept whole grains! D. Hire a personal trainer to help you get off your sofa.

E. Think of your body as a computer that needs some rebooting (重启). F. Go out to new restaurants or hiking trails to expand your experiences. G. Even if you have to work out slow at first, it’s better to start than not at all

6.根据短文内容,从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项.

As we all know, different countries have different cultures. The cultures of the East and the West really distinguish each other a lot. ①__________

The origin of the eastern cultures is mainly from two countries: China and India. Both of the two cultures are fostered by rivers—the Yellow River in China and the Hindu River in India. ②__________

Then in Tang Dynasty of China, the Chinese culture gradually went overseas to Japan, mixed into the Japanese society and shaped the Japanese culture nowadays. Though a bit different from the Chinese one, it belongs to the same system.

When the two mother rivers gave birth to the Eastern culture, another famous culture was

brought up on the Mesopotamian Plain—the Mesopotamian Civilization. This civilization later on developed into the cultures of Ancient Greece and Ancient Rome. ③__________Like the Chinese culture, the European one also crossed waters. When the British settled down in America, their culture went with them over the Atlantic Ocean. So the American culture doesn’t distinguish from the European one a lot.

④__________Take the language system for example. In the East, most languages belong to the pictographic language while the Western languages are mostly based on the Latin system. Other causes like human race difference counts as well. But what’s more, due to the far distance and the steep areas between the East and West, the two cultures seldom communicate until recent centuries. So they grew up totally in their own ways with almost no interference (干扰) from the other.

The differences are everywhere. ⑤__________But different cultures make the world of 21st century more colorful. The cultural gap should not be the obstacle (障碍) to the civilization of human being. It ought to be the motivation of our going farther. A. Let us work together to keep a variety of culture.

B. And these two are well-known as the base of the European culture. C. One important thing is to learn about other cultures.

D. They helped the two cultures develop for centuries and form their own styles.
