1 . Soldiers and other military people wear uniforms with various other symbols to indicate their status. But in the business world everyone wears more or less similar suits, and you cannot tell at a glance who ranks higher or lower than another. So how do people in the business world show their superiority?

An attempt to study this was made by two researchers using a series of silent films. They had two actors play the parts of an executive and a visitor, and switch roles each time. The scene had one man at his desk playing the part of an executive, while the other, playing the part of a visitor, knocks at the door, opens it and approaches the desk to discuss some business matter.

The audience watching the films was asked to rate the executive and the visitor in terms of status. A certain set of rules about status began to emerge from the ratings. The visitor showed the least amount of status when he stopped just inside the door to talk across the room to the seated man. He was considered to have more status when he walked halfway up to the desk, and he had the most status when he walked directly up to the desk and stood right in front of the seated executive.

Another thing that affected the status of the visitor in the eyes of the observers was the time between knocking and entering. For the seated executive, his status was also affected by the time between hearing the knock and answering. The quicker the visitor entered the room, the more status he had. The longer the executive took to answer, the more status he had.

1. The experiment designed by the two researchers aimed at finding out ________.

A．how business is conducted by all executive and a visitor

B．how businessmen indicate status

C．how to tell businessmen at a glance

D．how to tell the differences between an executive and a visitor

3. Having entered the room, the closer the visitor approaches the executive, ________.

A．the less it affected his status	B．the lower his status
C．the more it affected his status	D．the higher his status

4. The longer the seated man was in answering the knock, ________.

A．the higher his status was	B．the less it affected his status
C．the lower his status was	D．the more it affected his status

2 . Our brain is a wonderful and complicated organ.     1    

In recent years, scientists have discovered new ways to study the brain. They can now watch the activities of different parts of our brain while it is at work. We can think of these techniques as new windows on our minds.

    2     It can take pictures of your brain in much the same way as an X-ray machine can take pictures of your bones. This method makes use of the fact that whenever a part of your brain becomes more active, it uses more oxygen.

If someone were to use this technique to study your brain, your head would be surrounded by a machine that includes a big magnet (磁铁).     3     With the help of a computer, it turns these signals into pictures. By taking pictures every few seconds, scientists can tell which parts of your brain become active when you think of something, such as multiplying ten three times.

    4     Without stored memories, we would not be able to remember words we have learned or find our way home.

Everything we learn must be stored as memories in our brain.     5     Once a change is made, it must remain, even after the effort to learn has stopped.

A．One new research method is called FMRI.

B．This device can discover tiny signals coming from oxygen.

C．Most of our memories are stored away out of our awareness.

D．Storing memories is one of the most important jobs our brain does.

E．Keeping that information in our brain means our brain changes.

F．When we need them, they can be “copied” and placed for immediate use.

G．Scientists have been working for centuries to understand how it works.

4 . China has been planting seaweed for about 1,700 years . Coastal populations harvested a variety of algae first as a source of food and animal feed, but later for industrial and nutritional purposes as the practice became more widespread- Today, China remains the world’s biggest producer of farmed seaweed, but many other countries start to realize the potential of planting seaweed.

Certain red seaweed varieties contain up to 25% protein, but others are also rich in iron and other minerals. Seaweed planting becomes hot aquaculture which is now shooting up. In Alaska, where the largest seaweed farm in North America is located, farmers produced over 112,000 pounds of seaweed in 2019 — a 200% increase from Alaska’s first commercial harvest in 2017. Occupying just a few acres, seaweed planting is economical, relatively simple and comes with a lot of environmental benefits.

Research shows that seaweed could play a key role beyond serving as a source of nutrients and food, but also in the fight against some of the worst problems: climate change and ocean pollution. Seaweed doesn’t need to be fed or fertilized, as the crop gets everything it needs from sunlight and the natural nutrients already found in the ocean water. There are, of course, some disadvantages to seaweed farming. For example, overproducing seaweed could influence the amount of natural light available to other ocean species. In addition, technology for transporting, drying, and turning seaweed into biofuel and food can take up resources and give off CO₂. It’s also possible that these crops could remove too many nutrients from the wild ecosystem.

However, as research continues to search into sustainable seaweed farming methods, we may discover that advantages win over disadvantages.

The economic value of dealing with nutrient pollution, for example, may reduce costs for wastewater treatment; the same goes for turning seaweed into biofuel, fertilizer, or fuel depending on water quality. The balance will come down to a combination of policy and scientific research .

1. Why does the author mention seaweed farming in Alaska?

A．To show seaweed planting is growing fast.

B．To announce seaweed planting is eco-friendly.

C．To state seaweed is easy to plant across the world.

D．To prove seaweed planting has large economic benefits .

2. Which is the disadvantage of seaweed planting?

A．Removing other ocean species.	B．Consuming too many nutrients.

C．By using classifications.	D．By analyzing the background.

4. What can we infer about seaweed farming in the last paragraph?

A．There are arguments over it.	B．Turning seaweed into fuel is necessary.
C．It needs joint efforts to improve.	D．Dealing with nutrient pollution costs a lot.

5 . Ten years after introducing “Google Glass”, Alphabet Inc. has created a new kind of smart eyeglasses. The company says the wearable computer device can translate different languages in real time.

A working model of the yet-unnamed device was presented to the public this week during the yearly Google I/O developer conference. Google did not say when the glasses might go on sale to the public.

The first Google Glass device included a wearable camera that could film what the wearers saw. That caused widespread privacy concerns. The camera element also gave Google Glass a kind of science-fiction look. The latest device looks more similar to traditional glasses.

A brief demonstration of the new eyeglasses described its translation ability, but did not provide additional details. The company also did not say whether the new device would be equipped with a camera. A demonstration explained that a person, wearing the glasses and talking with someone who speaks a different language, can see the spoken words in their own language. The description showed translations involving English, Mandarin, Spanish and American Sign Language.

The new device is one of several products shared at the conference that are currently in development. The company says the products aim to better connect Google services with activities happening in the real world. This includes company offerings for searching and viewing maps, as well as other services using the latest developments in artificial intelligence.

Eddie Chung, a director of product management at Google, spoke to developers about the new eyeglasses. “What we’re working on is technology that enables us to break down language barriers, taking years of research in Google Translate and bringing that to glasses,” he said.
