1 . My cat wasn’t just my best friend, but she thought she was my protector. I once lounged under a tree, reading a book, while my cat sat across the lawn. When a small dog happened by, staring me in the face, my cat thought I was in danger. She raced across the lawn, all puffed up, meowing furiously to make the dog leave. ________________

A．My cat watched over me in the same way that I took care of her.

B．A feline (猫科动物) is a marvel of grace and ferocity (残忍) in the same lovely package.

2 . Two four-kilometer road tunnels are being built below the central area of the city, one for traffic to the north and the other for the traffic to the south. The two tunnels are about 20 meters below the surface and are 12 meters wide, providing for two lanes of traffic in each direction.

In the upper part of the tunnel, two air conditioning pipes remove the waste gas of trucks and cars and keep the quality of air inside the tunnel. The lighting is at the top of the tunnel, practically at its highest point. There will also be electric signs at frequent intervals. They show traffic conditions ahead and can be seen clearly by drivers. The wall is made up of four main elements, which include a waterproof covering and, on the inside of the tunnel, a concrete lining. Other systems in the tunnel will include emergency phones.

What is the main idea of the passage?

A．The construction of two lanes.	B．The function of a road.
C．The solution to cars’ pollution.	D．The design of two tunnels.

3 . Too often, we measure our worth not by the results we achieve, but by how much of our time we spend. We live crazy lives, at least in part, because it makes us feel good about ourselves.
What does the passage mainly concerned with?

A．The measurement of wealth in the current society.

B．The evolution of people’s attitude towards busyness.

C．The hidden reasons and effects of people’s busyness.

D．The solution to prioritizing the crucial tasks in busyness.

4 . Given its role in helping restore physiological peace, it appears that regardless of whether someone has BPD or not, it can be beneficial to learn to label your emotions. When you’re starting down the pathway of experiencing a negative emotion, you can benefit by applying an accurate label to that emotion as opposed to holding it back or calling it something else. This can potentially prevent engagement in destructive behaviors that may function to downregulate emotion such as self-harm.

To sum up, this new information about BPD can offer hope that at least one key element of the emotion regulation process appears to function effectively. Building on this strength could very well provide a new and unexplored pathway for their satisfaction.

What is the passage mainly about?

A．A new pathway of regulating emotions.

B．A method of consciously labeling emotions.

C．An unexpected strength of people with BPD.

D．An involuntary reaction to people with BPD.

5 . Search engines have changed the way we use the Internet, putting vast sources of information just a few clicks away. But Harvard professor of psychology Line Daniel Wegner’s recent research proves that websites and the Internet are changing much more than technology itself. They are changing the way our memories function.

Wegner’s latest study shows that when people have access to search engines, they remember fewer facts and less information because they know they can rely on “search” as a readily available shortcut.

Which of the following statements can be the best idea of the passage?

A．Relying on technology has weakened our critical thinking.

B．People heavily depend on computer for storing information.

C．Human’s capacity for memory is much weaker than it was before.

D．Computers and technology are reshaping the functions of our brain.

6 . People with a rare genetic disorder known as Prader-Willi syndrome never feel full, and this excess hunger can lead to life-threatening obesity (肥胖症). Scientists studying the problem have now found that the fist-shaped structure known as the cerebellum (小脑) — which had not previously been linked to hunger — is key to regulating satiation (饱食) in those with this condition.
What does the passage mainly talk about?

A．How our brain controls overeating.

B．How the aDCN works up our appetite.

C．How Prader-Willi syndrome can be prevented.

D．How lowering food intake benefits our overall health.

7 . In an effort to stop poaching (偷猎) and protect endangered species, people are using technology previously created to discover stars. Claire Burke, who led the project, says the application of the star­hunting tech has so far paid off big for conservation. “Since animals and humans in thermal imagery (热成像) ‘glow’ in the same way as stars in space, we have been able to combine the technical expertise of astronomers with the conservation knowledge of ecologists to develop a system to find the animals or poachers automatically,” she said in a statement.

In addition to species identification, the software can also provide an overview of health. Burke said that diseased or injured animals give off a different thermal imagery than the healthy ones. “The real advantage this gives you is that if you know how many animals you have and where they are and what kind of health they are in, then you can work out a good conservation strategy for looking after them,” she said.

The following is a post written by Burke on Twitter: More animals for the thermal imagery library. Thanks to Chester Zoo Science @ScienceatCZ for letting us observe their fantastic creatures. Images are giraffes, Indian elephants, and fruit bats.— Claire Burke (@CBurkeSci) October 27, 2017.

To train the software on a wide variety of heat signatures from different species, the team of researchers spent time collecting thermal imagery of animals. Their first field trial to detect Riverine rabbits, one of the most endangered mammals in the world (with only 500 living adults left in the wild), was a complete success. “The rabbits are very small, so we flew the drone (无人机) quite low to the ground at a height of 20 meters (65 feet). Although this limited the area we could cover with the drone, we managed to see the rabbit five times,” said Burke. “Given that there have only been about 1,000 times people have seen Riverine rabbits, it was a real success.”

What is the text mainly about?

A．Technology has helped a lot in helping the endangered animals.

B．Scientists use stargazing tools to protect endangered species.

C．What we should do to protect the endangered animals.

D．Scientists are working hard to protect the environment.

8 . Joshua Bingham studied 4 years at the University of Paris and decided to leave his graduation. He transferred to the University of Berlin and graduated with honors. Harvard Law School and, later, Boston College provided him with an excellent legal background. He is presently a corporation lawyer in Miami, Florida.

What is the main idea of the passage?

A．How Joshua Bingham became a lawyer.

B．Bingham is a diligent student.

C．Joshua Bingham received an excellent education.

D．A good lawyer needs good education.

9 . In the United States, old people who no longer have an income or who suffer from a loss of physical abilities are often forced to give up living alone. They must leave their homes and depend on someone else to give them a place to live and to take care of their physical needs: they must either live with relatives or live in homes for the aged. This loss of independence is a major problem for the aged.

Which of the following best expresses the main idea?

A．Old people in the United States who are poor or sick cannot live alone.

B．Being unable to live alone is a serious problem for old people in the United States.

C．Old people who are poor or sick should live with their relatives, not in homes for the aged.

D．In the United States, old people who are poor or sick are forced to live in homes for the aged.

10 . But actually, hacking is just an activity. What separates any activity from a crime is, very often. permission. People are free to drive, but they do not have permission to drive 150 miles per hour, which is a criminal offense. Since a driver is just a driver. why must a hacker be a criminal? Someone who engages in the illegal use of hacking should not be called a ‘bad hacker’ but a ‘cybercriminal’. Contrary to popular belief, most hackers like Mike’s father undoubtedly play an important role in keeping companies and people safe.

What message does the author really want to convey in the text?

A．Hacking mostly counts.

B．Hacking is actually a crime.

C．Hacking is popular with people.

D．Hacking needs licenses.
