Have you ever heard of spring fever? When we have spring fever, are we really sick? Originally, yes. 1. But now people used it to mean a sudden increase of romantic feelings.

These days, we use “spring fever” to describe a restless feeling after the long, cold days of winter. 2. It is also a verb that means something happening or appearing quickly.

Imagine that you are resting in the chair when suddenly you see a mouse run across the floor. You spring into action! You jump from the chair and run after the mouse! 3. And it works! But when you tell your roommate that you caught a mouse in a trap, tears spring from her eyes. You feel badly, but she really should have told you about her pet mouse Charlie!

4. You say to her, “You can’t just spring that on me! I’ll need time to find another roommate!” But then you think that maybe it’s for the best. Every time you see her you feel guilty about Charlie. 5. She always expects you to buy her things: she wants you to spring for lunch, spring for movie tickets, and sometimes even spring for groceries.

So, when you spring for something, you pay for someone else.

A. Many people suffer a lot from it.

B. You roommate turns her back on you.

C. But the word “spring” is not just a season.

D. Spring fever used to refer to an actual illness.

E. Then your roommate is moving out tomorrow.

F. That night you spring a trap with some cheese in it.

G. And anyway, she does something that really annoys you.

We all know cameras. But have you heard of Google’s new camera? It is a small, smart device, called Clips. It comes with a case that has a clip (夹子), but it’s not designed to be worn on your clothing. Most interestingly, it uses artificial intelligence to take photography out of your hands so it can capture moments on its own.

This roughly 2-inch by 2-inch camera, with a three-hour battery life and Gorilla Glass for toughness, is intended for candid moments, like when a child does something cute that may happen too quickly for you to pull out your smart phone.

Onboard the Clips device, it uses machine learning algorithms (计算程序) to help capture scenes. Those algorithms include face recognition. “Once it learns that there’s a face you see frequently, it’ll try to get nice photos of those faces,” said Juston Payne, the device’s product manager. And they also want it to recognize facial expressions, which involved “training it to know what happiness looks like”. The Google team also trained it to recognize what not to shoot—like when a child’s hand is over the lens, or if it is tossed in a dark purse.

The only way to see the images is by connecting the camera with your phone, as it has no screen for viewing or editing.

Did people think it was strange? Yes, Payne admitted. But they said they addressed that by making it obvious what it is. A green light on the front signals that the device is on. Besides, unlike a camera meant to monitor your home, it is not connected to the Internet.

“This product is only possible because of the way that technology has advanced,” Payne said. It was only in the past year or so that they could squeeze the technology down into a device this size. Going forward, we’re likely to get more assistance from the artificial intelligence packed into our apps and gadgets.

1.What is the most outstanding feature of Clips?

A. It is equipped with tough glass.

B. It enables easy Internet access.

C. It allows of hands-free photography.

D. It can be worn on your clothing.

2.What does the underlined word “candid” in Paragraph 2 probably mean?

A. Brief.　　 B. Touching.

C. Unforgettable.　　 D. Embarrassing.

3.What makes Clips a reality according to Juston Payne?

A. The popularity of the Internet.

B. The advance in technology.

C. The rise of the smart phone industry.

D. The reduction in the price of lens.

4.What is the best title for the text?

A. An Alternative Way to Photograph

B. New Gadgets in the Age of Apps

C. Artificial Intelligence in Everyday Life

D. A New Digital Camera from Google

You may have heard the expression “buying into the dip”. We usually think of this in terms of nesting (投资) --- for example, recessions (经济萧条) offer an opportunity to take advantage of buying cheap stocks that were once expensive.

But to me, “buying into the dip” is a term which covers a lot more than that. There are a few reasons that I was able to “buying into the dip” and start a business during the Great Recession: ChopDawg.com had zero upstart costs, with no need for any credit to get started. No loans, just $10 for the domain name. I picked a service that only required my own time and labor and that’s basically it, Not needing credit was a big deal for me, and I didn’t even think about this at the time.

I was also selling a service that was priced at just the right rock-bottom level to fill a need local small business badly needed more sales, since so many had cut their spending due to the recession. A website could give these businesses a new way to reach their customers, new and old.

From an economic standpoint, the Great Recession was an opportunity to start if you were selling the right thing at the right cost. During recessions, the pool gets way less crowded. Potential competitors become much more unwilling to risk, but for those who have an in-demand service, and the means to provide it, you are in business.

Back in 2009, website design had not yet become a commercial service, Offering web design as a service for small businesses was a novel idea, and many mom-and-pop shops didn’t know they needed it yet, which brings me to this: if you can solve a fresh-out-of-the-recession pain point at the right price, you have a chance of buying into the dip and helping a lot of people at the same.

1.What is “buying into the dip” to the author?

A.Selling things at low costs.

B.Buying cheap stocks in time.

C.Offering help to small businesses.

D.Starting a business with the least investment.

2.What does the underlined word “novel” in Paragraph 5 mean?

A.Familiar. B.Simple.

C.Clear. D.New.

3.What can be a suitable title for the passage?

A.Start small--very small.

B.Keep an eye on what you may need.

C.Serve right--quite right.

D.Adapt to changes in the Internet service.

Have you ever heard that we humans use only ten percent of our brains? This opinion holds a certain appeal because if it were true, then we could instantly become ten times more intelligent just by firing up that sleepy majority of the brain!

The idea that we use only a small part of the brain dates back to animal experiments in the 19th century. When scientists stimulated (刺激) a specific part of the brain,　 the animal moved its leg or tail. If a tiny part of the brain could do something so great, what was the use of the rest of the brain? Some scientists assumed that large parts of the brain were simply useless.

Then, in the early 20th century, scientists observed that stimulating certain parts of the brain had no physical effects. They named these seemingly useless parts of the brain the “silent cortex.” Today we know that in humans, much of the “silent cortex” is actually devoted to complex activities like language, learning, and imagining.

Brain scans have shown that different parts of the brain become much more active as we shift (切换) our attention and focus, but even as we sleep, many areas of the brain are extremely active. Would you be smarter if your entire brain constantly worked to maximum capacity (能力)? Interestingly enough, the opposite is probably true. The less brain activity you need to perform a given task, the more the brain as a whole is able to do.

1.Why does the opinion mentioned in paragraph l seem appealing?

A. People wish to become much smarter.

B. People believe it is scientific.

C. People know nothing about the brain.

D. People want to make little use of their brain.

2.What did scientists discover in their experiment in the 20th century?

A. The majority of the brain is sleeping.

B. Animals’ legs and tails have some connection with their brain.

C. Stimulation on some parts of the brain causes no physical reaction.

D. Certain parts of the brain are devoted to language and learning activities.

3.“Silent cortex” has proved to be______.

A. sensitive to stimulation

B. useful in complex activities

C. responsible for physical reaction

D. more active than the other parts of the brain

4.If you need less brain activity to perform a task, _______.

A. you will feel sleepy

B. you must shift your focus

C. you can use your brain to the fullest

D. you will be more productive
