It’s usual to hear of Chinese parents hiring a tutor（家教）if their children are doing poorly on tests. Did you know that teenagers can be tutors themselves? Amir Davis,16, from New York, US, is a tutor. Together with six other teens runs a special tutoring pro-gram for other kids in his community. The program mainly helps middle schoolers who have difficulties in their classes or who are preparing for a test called the Specialized High School Admissions Test （SHSAT）. It is an admissions test（入学考试）for eight STEM-Orien-ted（注重STEM教育的）public high schools in New York.

As an African-American student at one of these schools, Davis was sad to realize that black and Latino（拉丁裔的）students had low admission rates（录取率）every year. These groups hold only 10.4 percent of the students admitted these schools.

One of the reasons for the low admission rate is that a number of black and Latino students don’t take the SHSAT, with many families not realizing that they can take the test. So Davis tries to help kids in his area prepare for the test while also helping them with other schoolwork.

Davis and his team recently turned a building that his father bought into a tutoring center. During their tutoring, they first address what the students are doing in their classrooms. If they are having trouble with any specific topic, Davis or other tutors will walk them through it. With this help, the students can try to improve their knowledge of difficult sub-jects and do better in the classroom.

4. Davis runs a tutoring program to help ________.

A．students choose a good tutor

B．black and Latino students find better jobs

C．students with good grades become tutors

D．middle school students prepare for the SHST

5. Black and Latino students have low admission rates in STEM-oriented schools because ________.

A．most of them don’t work hard

B．they need tutors to help them with their school work

C．many schools don’t accept black and Latino students

D．many of them don’t realize that they can take a test to get in

6. What does the underlined phrase “walk them through it” mean?

A．take them away quickly	B．help them out easily
C．talk about the problem together	D．celebrate the success happily

7. What do we know from the story?

A．Davis’s parents support his program.

B．Davis is finding it hard to run the program.

C．Davis’s tutoring center makes a lot of money.

D．Kids don’t get much help from Davis’s tutoring.

Astronauts on board the International Space Station (ISS) once made history by taking bites of red romaine lettuce (长叶莴苣). They became the first humans to eat food that was grown in space. The lettuce was planted on the ISS in a small greenhouse called “Veggie”, which uses LED lights to help plants grow in space.

First, the astronauts cleaned the lettuce with special sanitizing wipes (消毒纸巾) and then ate it with some salad dressing.

“It was one small bite for man, one great step for ... our journey to Mars,” one astronaut, Scott Kelly, later, posted on social media.

Space vegetables are a part of the NASA, experiment called “Veg-01”, a study on how plants grow without the effects of Earth’s gravity (重力). It will allow astronauts to grow and eat their own food during long space explorations.

“If we’re ever going to go to Mars someday, we’re going to need a spacecraft that is much more self-sustainable (自给自足的) in its food supply.” said Kelly.

“Growing fresh plants on a spacecraft may also provide oxygen and help keep astronauts alive.” NASA said.

Veg-01 started in May 2014. The first part of vegetables, took 33 days to grow in space before they were taken back to Earth for a safety check. After making sure they were safe to eat, astronauts planted a second part on July 8. They let the plant grow for another 33 days and were then able to eat it. Astronauts usually only get vegetables when a supply ship comes to the ISS. Now with vegetables grown in space, they can eat them whenever they want.

8. Astronauts made history by ________.

A．working on the ISS	B．eating space-grown lettuce
C．cooking real food in space	D．building a small greenhouse

9. What is Veg-01?

A．It is a NASA project for exploring Mars.

B．It is the name of the greenhouse on the ISS.

C．It is a NASA experiment on how to grow plants in space.

D．It is a NASA experiment on eating vegetables safely in space.

10. According to Kelly, why is growing fresh plants in space important?

A．Because it provides people with healthier food.

B．Because it provides astronauts with enough oxygen.

C．Because it reduces the cost of sending food to the ISS.

D．Because it can help astronauts with their journey to Mars.

11. What’s the main idea of the passage?

A．What food astronauts eat in space.

B．How astronauts get food in space.

C．Astronauts’ work and life on the ISS.

D．The success of growing vegetables in space.

According to CNN，“Women still experience pay inequality（不平等）everywhere, whether you’re Hollywood’s top talent or you work in a store.”

Gender equality has improved in some areas like education. However, when females enter the workplace,     12    . Of the 145 countries and regions surveyed in a WEF （世界经济论坛）report, 97 have more female students than male students in universities. But only four of those countries and regions have a majority（多数）of female leaders in the workplace. “Women may only be viewed on the basis of their performance,     13    ,” The Washington Post wrote.

Old thinking about men and women is still influencing women’s careers, according to Saadia Zahidi, a WEF official. For example, many people believe boys are better at science, technology, engineering and math(STEM). And even today,     14    . Girls and women need to master the skills and training that are needed for the jobs of tomorrow, especially in the STEM fields, said Zahidi.

The gender gap（性别差距） in the workplace is not just about less pay for women. It’s also about women making sure their pay shows their value.

Actress Sandra Bullock once said, “Once we start changing how we think about women,     15    .”

To prevent the spread of the novel coronavirus, governments at every level in China have been using many different control measures.

In heavily-affected areas, the government has chosen to lock down cities. The decision proved effective（有效的）in stopping the virus’ spread at its root.

In some villages, people put up red banners（条幅）or used loudspeakers to educate people about the virus. Many communities also set up checkpoints to check people's temperatures， keep records of their travel history, keep non-residents（非住户）out of the community, and make sure that people quarantine（隔离）themselves after returning from high -risk areas. Some community workers also help those who are quarantined at home by bringing in food or drugs, taking out the garbage, and offering psychological（心理的）advice. The community workers have built the first line of defense（防御）_________ the virus across China. There are millions of community workers in 650,000 urban and rural communities across the country. Many people from all walks of life have volunteered to do this job.

“In the face of an unexpected outbreak, it’s amazing to see that China could mobilize（动员）people on such a large scale（规模），” Li Baoping from the Ningxia Academy of Social Sciences told Xinhua. “Great governance capacity（治理能力）at all levels gives us confidence in winning the battle.”
