Since it first opened after four years of construction in 1937 at a cost of $27 million，the Golden Gate Bridge has made its appearance in films and poetry.
CNN Travel spent a day climbing into and ground the bridge，learning these secrets from the people who know and love it best.
Why is it called the Golden Gate Bridge It’s not golden.
“The Golden Gate Bridge gets its name because it spans what is called the Golden Gate Strait，”said Paolo Cosulich-Schwartz，spokesman for the Golden Gate Bridge，Highway and Transportation District，which operates the bridge. It’s a three-mile-long and one-mile-wide body of water that connects the Pacific Ocean to the San Francisco Bay.
What color is the bridge It looks red.
“It’s not red，although you’re not crazy to think so. Visitors all call it red，”said Russell. “Back in the day，the US Navy，then part of the War Department，oversaw the waterways and wanted to paint this bridge black and yellow for high visibility，”said fellow painter Jarrod Bauer. “They ended up mixing paint to create the color International Orange，which is similar to the color of red lead，”he said.
Does the bridge get entirely painted every year
No，and it doesn’t need to be. It’s true that the top coat has been fully repainted over time with new and environmentally-improved International Orange top coats.
Who performs bridge rescues
McVeigh and his fellow ironworkers，the so—called “Cowboys of the Sky”，have that responsibility. McVeigh has lost count of how many troubled souls he’s been called to rescue over the past 17 years.
In September in 2018，the bridge started constructing a suicide(自杀)prevention system，also known as the safety net，to keep people from jumping off the Golden Gate Bridge. It’s expected to be completed in 2021.
1．What’s the true color of the Golden Gate Bridge
A．Red. B．Red lead.
C．Black and yellow. D．International Orange.
2．Who can probably be called a hero on the Golden Gate Bridge
A．McVeigh. B．Jarrod Bauer.
C．Russell. D．Paolo.
3．What can we know about the Golden Gate Bridge
A．It is safer now because of the safety net.
B．It got its name because of its color.
C．It took much time and money to be built.
D．It needs to be repainted once a year.
B
The first “mobile phone sidewalk in China” has appeared at a scenic spot in Chongqing. The sidewalk， 3 meters wide and 50 meters long, was built in the Yangrenjie Scenic Spot. It separates pedestrians along two path ways. One is for cell phone users to walk on; the other is for those without cell phones.
A warning sign shows: Cell phones walk in this lane at your own risk. “In my mind, these sidewalks help a lot in minimizing security risks for mobile phone addicts,” said Wang Li, a local resident who doesn't use a mobile phone often. Cases of mobile phone users being injured while using their phones and ignoring their surroundings have been reported by the media. Tourists who were attracted to the sidewalk took photos of it. But many did not comply with the regulation, and someone even parked a car on the sidewalk.
Li Zhijiang, a 20-year-old college student from Guizhou, regarded the sidewalk as great progress. “I knew there were such sidewalks in Washington central business district, which are very necessary for the addicts, especially in the busy streets,” Li said. Anthony Edwards. a 28-year-old actor from England, was enthusiastic, saying it was an improvement over his home country. However, his Chinese colleague, Xing Xing, thought the sidewalk was “pointless, but added an acknowledgement.”Setting up special sidewalks could be a solution to reducing security problems in particular situations. But this kind of sidewalk is not a fundamental solution and could be negative for mobile phone addicts in the long run in my mind and this could even lead to more problems in the future.
With the increasing popularity of smart phones, more young people in China are addicted to them, a problem that worries many experts. It is estimated that the number of smart phone users in China will be more than 500 million this year.
4．What is the purpose of the mobile phone sidewalk
A．To avoid being crowded. B．To reduce the security risks.
C．To control the people's behavior. D．To make it convenient to walk in the street.
5．What can be used to replace the underlined phrase “comply with” in paragraph 2

B．The necessity of building the mobile phone sidewalk
C．The problems of the mobile phone sidewalk in the future.
D．The safety measures to protect the mobile phone sidewalk.
7．What do many experts worry about

C．More young people being addicted to cell phones.
D．The mobile phone sidewalk being ruined in the future.

My first year living in Los Angeles, I was a birthday-party clown. I struggled a lot with my identity because, I viewed myself as an artist while others viewed me as ridiculous. To make matters more confusing, being a clown is itself an identity-masking job.
One night, I was asked to play as Batman. At the time I had a giant mustache. But I didn’t want to change my physical appearance, because that would have been me admitting I was more of a clown than an artist. So I chose not to shave.
The next day, I went to the party. Once I got close enough for the kids to make out the features of my face, the entire party burst into laughter. I was so embarrassed. But then came loud applause. Feeling kind of warm, I was thinking, “Is this what encouragement feels like It’s so new.” I was still about 20 yards away from the party when I started running. They all started cheering louder, and at that moment, I was Batman.
“You see, son. I told you Batman has a mustache.” said father of the birthday boy. I saw a huge Birthday cake with a frosting Batman drawn on it, and the Batman had a mustache. I stared at it in disbelief. That’s why everyone was laughing so hard when I first arrived, because when they brought the cake out, all the kids laughed, “Batman doesn’t have a mustache.” Instead of admitting the cake was messed up, the parents tried to save face and said, “No, Batman always has a mustache. He just shaves it for his movies.”
Naturally, the children were doubtful. But they were at the perfect age where they still believed in miracles. My mustache became the detail that confirmed what the parents had said and convinced the kids that I was actually Batman.
That year, I struggled a lot with my identity: was I an artist, or was I a clown But that day, at least, there was no doubt in my mind what I was.
8．How did the author feel about his work as a clown at the beginning
A．He was enthusiastic about his job. B．He had to depend on it to feed himself.
C．It made him confused about his identity. D．Being a clown is the first step to an artist.
9．Why did the author refuse to shave his moustache
A．Because the real Batman had a moustache.
B．Because he wanted to give the birthday boy a surprise.
C．Because the birthday boy’s father asked him not to shave.
D．Because he regarded himself as an artist rather than a clown.
10．How did the kids react when seeing Batman with a moustache
A．They applauded but lost interest soon.
B．They believed Batman had a moustache at once.
C．They ignored his moustache and played as normal.
D．They laughed loudly because of his ridiculous moustache.
11．What can we learn from the story
A．Every effort you make will pay off in the end.
B．Never give up struggling with the unfair world.
C．We can find our own identity even in an ordinary job.
D．Every child is an angel that believes in all good things.

The benefits of regular exercise are well documented but there's a new bonus to add to the ever-growing list. New research found that middle-aged women who were physically fit could be nearly 90 percent less likely to develop dementia (失智症) in later life- and if they did, it came on a decade later than less sporty women.
Lead researcher Dr Helena H rder, of the University of Gothenburg in Sweden, said: “These findings are exciting because it’s possible that improving people’s cardiovascular (心血管的) fitness in middle age could delay or even prevent them from developing dementia.”
For the study, 191 women with an average age of 50 took a bicycle exercise test until they were tired out to measure their peak (最大值的) cardiovascular capacity. The average peak workload was measured at 103 watts.
A total of 40 women met the criteria for a high fitness level with a capacity of 120 watts or higher,while 92 women were in the medium fitness category. A total of 59 were of low fitness level, with a peak workload of 80 watts or less, or having their tests stopped because of health problems.
These women were then tested for dementia six times over the following four decades. During that time, 44 of the women developed dementia. Five percent of the highly fit women developed dementia, compared to 25 percent of the women with medium fitness and 32 percent of the women with low fitness.
“However, this study does not show cause and effect between cardiovascular fitness and dementia, it only shows an association.” said H rder. “More research is needed to see if improved fitness could have a positive effect on the risk of dementia and also to look at when during a lifetime a high fitness level is most important.” She also admitted that a relatively small number of women were studied, all of whom were from Sweden, so the results might not be applicable to other groups.
12．What is on the ever-growing list mentioned in the first paragraph
A．Positive effects of doing exercise.
B．Exercises suitable for the middle-aged.
C．Experimental studies on dementia.
D．Advantages of sporty women over men.
13．Why did the researchers ask the women to do bicycle exercise
A．To predict their maximum heart rate.
B．To assess their cardiovascular capacity.
C．To change their habit of working out.
D．To detect their potential health problems.
14．What do we know about Dr H rder’s study
A．It aimed to find a cure for dementia.
B．The results were far from satisfactory.
C．Some participants withdrew from it.
D．Data collection was a lengthy process.
15．Which of the following is the best title for the text
A．More Women Are Exercising to Prevent Dementia
B．Middle-Aged Women Need to Do More Exercise
C．Fit Women Are Less Likely to Develop Dementia
D．Biking Improves Women’s Cardiovascular Fitness

You can control your weight better. More than half of the Americans are overweight or obese, and obesity contributes to 1 in 5 American deaths. Simple healthy choices such as replacing soda with water, choosing vegetables instead of chips, and ordering a side salad in place of French fries will not only help you lose weight, it also can help you save money. 19
A relatively longer life is expected. The same diseases that make you feel bad and cost a lot of money may also decrease your life expectancy. Many studies show a healthier diet relatively leads to a longer life.

Caught in “the Web”!
Dave and Kelly loved their computer. Their parents got it for them a couple of months ago, and they had taught their kids how to use it. They bought some computer games for the kids to play and connected the computer to the Internet. The kids loved going on the Internet and visiting websites. They got to do research for their homework, play games, print colouring pages and read stories. They also got to email their friends and even chat with other kids, after getting their parents’ permission.
Because the kids liked the Internet so much, they would finish their homework, and then go to surf the Internet. Very often, they didn’t feel the passage of time and found themselves almost falling asleep in front of the computer screen.
One day they stayed up late surfing the Internet after they were done with their homework. They watched a video about a science fiction story, which described two alien species hunting human information, because aliens had a wicked intention to conquer the Earth. The species coming from a distance tried to collect every aspect of data about humans, but in vain. They were detected and driven away by watchful humans. After a while they started getting tired and they were almost falling asleep. While they were in the twilight between being asleep and being awake, they felt a strong suction coming from the computer screen. It felt like a huge vacuum cleaner!
By now, they were fully awake, but when they looked around, they did not see their living room anymore. Instead, they were drawn into the computer itself by that mysterious power. They were surrounded by a complex system of tubes and small boxes and columns. They were all in different shapes, such as being tall, short, wide, narrow, round, square, etc. More strangely, they all felt a little warm and some even were shining with real, blue or orange light. They saw themselves floating in a long tube with speeding chunks of alphabets, numbers, images and sounds. They were INSIDE the computer!
注意:续写词数应为150左右。
Their dream came true and they decided to let loose and drift along the long tubes and have some fun.

46．Dear Tom,
How are things going with you Hearing that you are also having online classes at home, I’d like to share with you my opinion about it. Since the outbreak of the COVID -19, we have experienced a long period of online classes, which have benefited us a lot. First, without teachers’ guidance in person, it is an opportunity to improve our ability of self-control, encouraging us to keep focused on what we are learning. Additionally, we can communicate more with teachers online whenever we have questions. However, for online classes, there is a lack of classroom learning atmosphere. It could be more effective if we are provided with more interactions when taking the lessons.
I am looking forward to hearing from you.
Yours,
Li Hua

47． Their dream came true and they decided to let loose and drift along the long tubes and have some fun. They travelled all over the world and they found themselves even in the White House; they found it was fun to spy on people that couldn’t see them. They travelled through the long tubes to see things and people that they had always wanted to see. They got to watch the president who stayed up and they were the first ones to know about his new decisions. They had a blast.
But after a few days they started missing something and that was the feel of love. Life wasn’t all that fun without a hug from their mama and daddy; they wanted to come home but how could they There was only one way and that was through the heart. They had to want to come back so badly that it even meant they had to listen to the rules that Mum and Dad made and do research for schoolwork instead of playing computer games so much. They finally opened their eyes as their mother said it was time to get up for school.
