If I had to pick just one site to help with restaurant recommendations around the US, it would be .

2.
basically helps you figure out where you can fly within your budget. It’s sort of like the “explore” page of , but focuses mainly on Europe, and on very, very cheap flights.

Then go through their listings of top attractions, museums, shopping, restaurants and something else, clicking on whatever appeals to you.

The US film industry may have generated profits somewhere in the region of $40 billion last year, but it seems Hollywood still has plenty of work to do if wants to compete with the most popular American institution: the public library.
Yes, according to a recent Gallup poll (民意调查), which was the first such survey since 2001, visiting the local library remains by far the most common cultural activity American join in. As reported earlier today by Justin McCarthy:
“Visiting the library remains the most common cultural activity American join in, by far. The average 10.5 trips to the library US adults report taking in 2019 exceeds their participation in eight other common leisure activities. Americans attend live music or theatrical events and visit national or historic parks roughly four times a year on average and visit museums and gambling casinos (赌场) 2.5 times annually. Trips to amusement or theme parks (1.5) and zoos (0.9) are the least common on activities among this list.”
The results of the Gallup poll have been broken down in a range of different ways, all of which you can peruse (研读) at your leisure, but two of the more interesting, though unsurprising, findings are that women report visiting the library nearly twice as frequently as men do, and that libraries are visited most by adults in low-income households and least by adults in high-income households.
Congratulations to all you librarians out there; keep fighting the good fight. Pour one out for the zookeepers, though; it appears the zookeepers may be jealous and feel it not worth staying at the zoo.

A．An adult man from a rich family. B．An adult man from a poor family. C．An adult woman from a rich family. D．An adult woman from a poor family. 11．What is the tone (语气) of the author in the last paragraph?
A．Serious. B．Optimistic (乐观的). C．Humorous. D．Inspiring.
Role models (榜样) are important for inspiring (鼓舞) scientists, but new research suggests that scientists who are known for their hard work are more motivating (激励人的) than scientists who are viewed as naturally brilliant.
In a series of studies, researchers found that young people were more motivated by scientists whose success was connected with effort than those whose success was because of born intelligence, even if that scientist was Albert Einstein.
Danfei Hu, a doctoral student at Penn State, and Janet N. Ann, an assistant professor of psychology at William Paterson University, said the findings — recently published in Basic and Applied Social Psychology — will help deal with certain secret about what it takes to succeed in science.
According to the researchers, there is concern in the science community with the number of students who run after careers in science during school only to drop out from those career paths once they graduate from college. To help solve the problem, Hu and Ahn wanted to research role modeling (行为榜样), which gives the students specific goals, behaviors or strategies (策略) they can follow.
The researchers performed studies with 176, and 162 participants (参与者) in each, respectively. In the first study, all participants read the same story about common struggles a scientist met in their science career. However, half were told the story was about Einstein, while half were told it was about Thomas Edison. Although the stories are the same, participants were
more likely to believe natural brilliance (才华) was the reason for Einstein’s success. In addition, the participants who believed the story was about Edison were more motivated to complete a series of math problems.
“This proved that people generally seem to view Einstein as a genius, with his success commonly linked to extraordinary talent,” Hu said. “Edison, on the other hand, is known for failing more than 1,000 times when trying to create the light bulb, and his success is usually linked to his effort.” Hu added, “Knowing that something great can be achieved through hard work and effort, more students will step into science confidently. “
12．What kind of scientists are more motivating?
A．Those who are famous around the world.
B．Those who are famous for their hard work.
C．Those who are viewed as naturally brilliant.
D．Those who are viewed as great in ventors.
13．What is the concern in the science community?
A．Fewer students will work on science.
B．The students will drop out of school soon.
C．There are fewer role models for students to follow.
D．Some scientists can not give students specific goals.
14．Why were some participants motivated to complete a series of math problems? A．They knew the problems were given by Edison.
B．They believed they were as intelligent as Einstein.
C．They believed they could solve the problems by working hard.
D．They knew they were to work together with Einstein and Edison.
15．What is the best title for the text?
A．Einstein’s Success Story
B．Edison’s Achievements Are Greater
C．How to Be a Great Scientist
D．Einstein Is Less Encouraging Than Edison

We should consider AI not as something competing with us, but as something that can
strengthen our abilities. 16．And it might help keep us safe in the 21st century.

A．Record the locations smartly.
B．Keep the balance of power supplies
C．Thus, the farmers can have a good harvest.

推理判断题。

根据第一段The US film industry may have generated profits somewhere in the region of $40 billion last year, but it seems Hollywood still has plenty of work to do if wants to compete with the most popular American institution: the public library.美国电影业去年创造的利润可能在400亿美元左右，但好莱坞要想与美国最受欢迎的机构——公共图书馆竞争，似乎还有很多工作要做。

9．
词义猜测题。

根据文章第二段第一句Visiting the library remains the most common cultural activity American join in, by far. 到目前为止，访问图书馆仍然是美国人参与的最普遍的文化活动。

根据文章第四段findings are that women report visiting the library nearly twice as frequently as men do, and that libraries are visited most by adults in low-income households and least by adults in high-income households. 可知女性去图书馆的频率几乎是男性的两倍，低收入家庭的成年人去图书馆最为频繁，而高收入家庭中的成年人去图书馆频次最少，综合内容得知，低收入家庭中女性最可能去图书馆。

推断隐含意义，即要求根据文章的某个句子、段落或全文所提供的事实进行逻辑推理，推断出作者没有提到、没有明说或者可能发生的事实。

题干中常含infer（推断），suggest（暗示），imply（暗示），indicate（暗示），conclude（推断，得出结论）等词语。

解此类题，首先找到相关信息，然后细读、理解相关信息的字面意义，最后结合语境和常识，在字面意义的基础上进行符合逻辑的推断，从而理解作者的言外之意。

如小题4，根据文章最后一段第二句Pour one out for the zookeepers, though; it appears the zookeepers may be jealous and feel it not worth staying at the zoo. 可知作者说大家也应该匀出一点热情给动物
园的管理员，或许人家会感到在动物园工作都不值得了，由此判断出这是一种幽默的语气，故选为C。

故选A
14．
细节理解题。

根据第五段关键句“In addition, the participants who believed the story was about Edison were more motivated to complete a series of math problems.”可知参与者完成数学题是受到爱迪生的鼓舞。

再根据最后一段关键句“Edison, on the other hand, is known for failing more than 1,000 times when trying to create the light bulb, and his success is usually linked to his effort.”可知，爱迪生在尝试制造灯泡时失败了1000多次，他的成功通常与他的努力有关。

综合上述句子可以得知这些相信爱迪生故事的参与者们相信通过努力工作可以解决问题，所以才有动力去完成一系列数学题。

故选C项。

15．
主旨大意题。

根据文章内容及文章第一段关键句“scientists who are known for their hard work are more motivating (激励人的) than scientists who are viewed as naturally brilliant”可知，文章主要阐述的是那些以努力工作而闻名的科学家比那些天生才华横溢的科学家更能激励人心。

D项“Einstein Is Less Encouraging Than Edison”中的Einstein代指天生才华横溢的科学家，Edison代指以努力工作而闻名的科学家，意为“天生才华横溢的科学家没有以努力工作而闻名的科学家鼓舞人心”，能够表达文章主旨。

根据文章第一段关键句“scientists who are known for their hard work are more motivating (激励人的) than scientists who are viewed as naturally brilliant”可知，文章主要阐述的是那些以努力工作而闻名的科学家比那些天生才华横溢的科学家更能激励人心。

而文章中又分别列举了Einstein和Edison两位科学家的例子，根据文章内容可知，Einstein代指天生才华横溢的科学家，Edison 代指以努力工作而闻名的科学家，故可推断出D项“Einstein Is Less Encouraging Than Edison”能够表达文章主旨。
