Research on the human brain has been attracting more and more scientists in recent years, just like the booming hi-tech industry. One of the latest research topics is how to change the human brain or combine the computer and the human brain, i.e. to transplant a chip into a human brain. This idea may make everyone’s dream come true. If we compare a human brain to a hard disc, what the scientists are doing is to enlarge the capacity of the hard disc. For the time being, there are some difficulties in such transplant experiments, but scientists never give up.

Experiments have started on animals. In 1996, a transplant experiment performed at the Defense and Military Physiology Research Institute in the U.S. turned a bear into a dolphin.

The dolphin was named Ted, and the bear was named Tallin. Using the most advanced technology available, deep and detailed images were made of the memory area in Ted’s brain containing information about swimming by the scientists. They obtained a series of useful information, the signals transferred by the nervous system. Such information was saved into a button-sized chip, which was then transplanted into the action memory area in Tallin’s brain. The information saved on the chip was released by means of electric power.

Recently, another comprehensive memory transplant was performed at the Motor Nerve Research Institute of the University of California. The comprehensive memory transplanted in the experiment included actions, moods, logic, words, images, etc. The experiment involved an entire transplant of the memory area. This was the largest such experiment done so far.

The transplant was performed making a transfer from a dog named “Genius” to a dog named “Idiot”. “Genius” could understand and follow up to 100 gestures and orders made by its master. It was a real genius in memorizing. “Idiot” was the younger brother of “Genius”. It had no contact with people at all since its birth. It became an animal with nothing in its brain, without any memory.

The operation was a complete success. When the two dogs woke up, “Idiot” had grasped all the abilities “Genius” possessed; it was good at memorizing and sensible. It could follow every gesture and any command given by its master. But “Genius” gave no response to its master, and in fact did not recognize him at all.

1.The purpose of the experiment is ________.

A. to combine the computer and the human brain

B. to make bear swim

C. to make some stupid dog turn clever

D. to enlarge the capacity of human brain

2.Which of the following statements is TRUE?

A. The scientists transferred a button-sized chip with useful information in Tallin’s brain.

B. The first comprehensive memory transplant was performed at the Motor Nerve Research University.

C. The second experiment wasn’t an entire transplant of the memory area.

D. The Idiot was an animal with memory before brain experiment

3.What does the underlined word “success” refer to?

A. The two dogs woke up.

B. They were both good at memorizing.

C. The Idiot grasped all the abilities of Genius.

D. The Genius grasped all the abilities of Idiot.

4.According to the text, we can infer ________.

A. a person can know more after the experiment

B. a bear can swim after being transferred a chip with related useful information

C. a dog can become clever after entire transplant of the memory area

D. it is really good for animals to have been involved in the transplant experiment

The COVID-19 pandemic has spread far and wide. Because of this, countries around the world have carried out containment measures to help stop the virus in its tracks. As more and more people stay inside to stay safe, the outside world seems to have become much quieter. In fact, scientists have seen this change in their research, too.

Seismologists—scientists who study earthquakes—have heard a lot less seismic (地震的) noise recently. Seismic noise is made from vibrations (震动) in the ground that are caused by things like ocean waves and human activity, such as construction work and traffic.

Thomas Lecocq, a scientist at the Royal Observatory of Belgium, located in Brussels, was the first to notice this phenomenon. According to Lecocq, the amount of seismic noise in Brussels has been reduced by about 30 to 50 percent since mid-March. Interestingly enough, this is around the same time Belgium started its containment measures.

Because of this reduction in background noise, scientists like Lecocq have been able to pick up on smaller earthquakes that some seismic stations—like the one in Brussels—wouldn’t have been able to before.

This phenomenon isn’t unique to Brussels, though. Once Lecocq shared his findings online, seismologists from all over the world echoed similar findings. Celeste Labedz, a graduate student at the California Institute of Technology, mentioned in a tweet that Los Angeles also experienced less background noise. “The drop is seriously wild,” she wrote. Researchers from the UK, France and New Zealand also noted a decrease in background noise since containment measures were put in place.

These global efforts to contain the COVID-19 virus have helped to shed light on seismic activity that may have gone unnoticed. It also shows that people are listening to health officials and following lockdown guidelines.

1.What did seismologists find out recently?

A.More smaller earthquakes are likely to happen.

B.Less seismic activity has been detected recently.

C.Reduced seismic vibration makes Earth quieter.

D.Seismic noise is caused by vibrations underground.

2.What can we learn from the text?

A.More seismic noise is being picked up.

B.More data on smaller earthquakes is being collected.

C.Scientists will shift their focus to smaller earthquakes.

D.Future big earthquakes can be more accurately predicted.

3.What does the underlined word “echoed” in paragraph 5 mean?

A.Questioned. B.Demanded.

C.Explored. D.Repeated.

4.What can we conclude from the last two paragraphs?

A.The drop in seismic noise is unique to Europe.

B.Seismic noise is mainly caused by human activity.

C.Many seismologists wanted tighter restrictions for their research.

D.The phenomenon proved that people are practicing social distancing.
