Many years later, when people recall the 2018 Russia World Cup, they will remember many things. With the tragic ending of the defending champion Germany, Mexico has triumphantly and suddenly lost three goals in the face of Sweden. But people will never forget the back of a lonely person . That is Lionel Messi.

31-year-old Messi took off the green armband of his left arm and suddenly fell out. In the recent match, he and his team lost the game against France. The 19-year-old striker Mbappé relentlessly ripped apart the Argentine defense line and scored twice, which made a great contribution to the victory of France.

On this planet, anyone who knows a little about football knows the name Lionel Messi and his golden years from 2007 to 2017.

In 2007, 19-year-old Messi tied Real Madrid three times with a hat-trick, and began his legendary career.

In the past ten years, Mr. Football, the Golden Globe Award and the Golden Boot Award have been taken over by him.

He led Argentina and Barcelona to make a name for themselves in the world, and has a brilliant record in the Champions League, America's Cup and World Cup.

Eleven years later, Messi stood on the Kazan Stadium. After four World Cups, he knew that this might be the last time he led Argentina to the World Cup.

Since 1986, Argentina has never won a championship again. As a captain, he has a great responsibility, even stating that he would withdraw from the national team if he did not win the championship this year.

This is a prophecy.

Messi, who eventually failed to save the game, did not receive any interview after standing up on the lawn; leave behind only a legendary image for the world.

1.The underlined word “relentlessly” in paragraph 2 is closest in meaning to __________?

A. mercilessly    B. bravely

In cooperation with German experts, Several scientists from the University of Bradford believe that they finally solved a mystery that has been confusing millions of people: why our hair turns gray with age.

The researchers came up with their results by examining native hair and cells from human hair follicles(毛囊). They say the secret turns out to be hidden in catalase(过氧化氢酶), which is causing hair to turn gray.

Catalase production goes down with age and stress, allowing hydrogen peroxide(过氧化氢) in the hair to do its favorite job—making hair gray, and then white, by blocking the normal production of melanin(黑色素). Melanin is our hair's natural pigment that is responsible for the color of hair. It also determines the color of our eyes and skin.

Dr. Gerald Weizmann, an editor of a journal, says," All of our hair cells make a tiny bit of hydrogen peroxide, but as we get older, this little bit becomes quite a lot, and our hair turns gray and then white."

The new study brings hope for millions of people who have to color their hair: to finally obtain some shampoo that will decrease levels of hydrogen peroxide and therefore restore gray or white hair to its natural color or even prevent it from turning gray.

The researchers are already conducting an experiment with such a drug on a few volunteers with gray hair and expect to get the results in the next two to three months. If everything works out, millions of people will choose between this drug and other previously used expensive dyes. However, even if the drug works, it will take at least several years before it can be brought to the market.

1.What is the passage mainly about?

A. The effect that gray hair has on people.

B. The chemical elements of people's hair.

C. The reason why people's hair turns gray.

D. New drugs to prevent people's hair from turning gray.

2.According to the passage, people's hair turns gray because of______.

A. a decrease in catalase    B. the death of hair cells

C. the production of melanin    D. a decrease in hydrogen peroxide

3.Which of the following statements is TRUE according to the passage?

A. The new study shows it's harmful to color our hair with dyes.

B. Dr. Gerald Weizmann is in charge of the new drug experiment.

C. Our hair cells make lots of hydrogen peroxide when we are young.

D. We may restore our gray or white hair to its natural color with shampoo.

4.What can we learn from the last paragraph?

A. Only a small number of people can use the new drug.

B. Most of the volunteers in the experiment are old people.

C. The drug cannot be brought to the market soon even if it works.

D. The researchers have already known the results of the experiment.

Our family loves the snow and cheers at the first good storm of the season. While others may think of Florida, we dream of a cabin vacation in New York’s Allegany State Park.

One particular trip, I recall, was just a bit more memorable than the rest. What we now refer to as the snow pants incident began accidentally enough. My husband, Bernie, and our 2-year-old daughter, Faith, were building a snow fort while I sledded down a nearby slope.

On the way back up from one trip, I saw a small stone tumbling down the track I had just made. I was puzzled, since all the other rocks were buried under several feet of snow, as I stood and wondered about the stone---it jumped! This was no stone. This was a mouse.

Now, I love nature, but that doesn’t include mice. I loudly protested the invader, and Bernie, coming to my rescue, assured me that this was not a mouse but a mole, as if that mattered. A mouse or a mole I still didn’t like it.

Bernie and I stood for a few minutes watching the creature disappear from the path into the furry white and come back out again. But soon it disappeared and I headed up the hill again.

Shortly after I left, my husband screamed out, saying that the mole had gone up the leg of his snow pants. You have to understand Bernie can be quite a joker, and I smelled a rat. Not wanting to be a sucker and fall for another one of his jokes, I laughed it off. When he started running for the cabin, though, I stopped laughing and decided maybe this was for real.

“Don’t you dare take that thing into the house!” I yelled. But like a flash, Bernie was already dashing through the cabin’s front door, with his snow pants, the mole and all. If it were me, I’d have been down to my long underwear right there in the snow without a second thought.

A few minutes later Bernie appeared. We relished the rest of our winter vacation, drinking lots of hot chocolate, sitting beside the fireplace and admiring nature---from a safe distance.

1.Why did the author’s husband come to her rescue?

A. Because the “mouse” frightened her

B. Because she hardly controlled the sled

C. Because the snow fort she built was damaged

D. Because she stepped on the stone and fell down

2.When her husband said that the mole had gone up the leg of his snow pants, the author was ___.

A. curious    B. puzzled

C. excited    D. doubtful

3.What can be inferred from the last paragraph?

A. They enjoyed the rest of their holiday

B. They were fond of hot chocolate

C. Her husband had freedom at last

D. Nature can be dangerous at times

4.What could be the best title of the text?

A. A Memorable Experience with a Joker

B. The Painful Incident in Allegany State Park

C. Family’s Funny Vacation in the Snow

D. My Strong Love for Nature
