【題目】 Personal growth would be a good way to sum up Tarik Black. Indeed, at this very moment, the man himself is sporting a ski cap with the words “Be More" on it, which he takes to heart.

While many other former NBA players would be busy padding their own pockets, he has taken the opposite approach: creating a charity to help underprivileged youth in the U. S. The Tarik Black Foundation aims to inspire kids and prepare them to become successful adults. The organization is based in Memphis , where Tarik Black grew up and play ed college basketball.

They organized an art show in Los Angeles where the teenagers got dressed formally and learned how to

socialize with others. In Houston, they partnered with the National Tennis Association for a charity event.

“My mother would drive me around Memphis and show me people who are growing up in circumstances that don't have opportunities. She would always tell me, 'If you ever get a chance to give back to these people , then you must," he says, leaning back into the chair.

The family moved to Israel in the summer of 2018 , when Black signed with Maccabi Tel Aviv, Israel's best basketball powerhouse. And the Maccabi Tel Aviv season will end just in time for him to return to Memphis to . conduct his summer camps in July, 2019.

It's still up in the air if Black will be coming back for a second season in Tel Aviv. But he's not worried.“Honestly, the doors are open for us to seek after anything we want if you keep a big picture in mind.”

【題目】 When “Rise of the Planet of the Apes” was first shown to the public last month, a group of excited animal activists gathered on Hollywood Boulevard. But they weren’t there to throw red paint on fur-coat-wearing film stars. Instead, one activist, dressed in a full-body monkey suit, had arrived with a sign praising the filmmakers: “Thanks for not using real apes (猿)!”

The creative team behind “Apes” used motion-capture (動(dòng)作捕捉) technology to create digitalized animals, spending tens of millions of dollars on technology that records an actor’s performance and later processes it with computer graphics to create a final image (圖像). In this case, one of a realistic-looking ape.

Yet “Apes” is more exception than the rule. In fact, Hollywood has been hot on live animals lately. One nonprofit organization, which monitors the treatment of animals in filmed entertainment, is keeping tabs on more than 2,000 productions this year. Already, a number of films, including “Water for Elephants,” “The Hangover Part Ⅱ” and “Zookeeper,” have drawn the anger of activists who say the creatures acting in them haven’t been treated properly.

In some cases, it’s not so much the treatment of the animals on set in the studio that has activists worried; it’s the off-set training and living conditions that are raising concerns. And there are questions about the films made outside the States, which sometimes are not monitored as closely as productions filmed in the States.

【1】Why did the animal activists gather on Hollywood Boulevard?

A.To see famous film stars.

B.To oppose wearing fur coats.

C.To raise money for animal protection.

D.To express thanks to some filmmakers.

【2】What does paragraph 2 mainly talk about?

A.The cost of making “Apes.”

B.The creation of digitalized apes.

C.The publicity about “Apes.”

D.The performance of real apes.

【3】What does the underlined phrase “keeping tabs on” in paragraph 3 probably mean?

A.Listing completely.

B.Directing professionally.

C.Promoting successfully.

D.Watching carefully.

【4】What can we infer from the last paragraph about animal actors?

A.They may be badly treated.

B.They should take further training.

C.They could be traded illegally

D.They would lose popularity.

科目：高中英語(yǔ) 來(lái)源： 題型：

【題目】 With an improved economy，many travelers have been buying first or business class seats，leaving fewer for upgrades（升級(jí)）.Here are some strategies for getting a free upgrade.

1. Fly a lot.

This is the most common way to earn a free upgrade. Most airlines reserve some spaces for travelers who fly at least 5，000 miles per year. Five years ago，this meant half or more of domestic（國(guó)內(nèi)的）first class travelers sat up front for free. But now，airlines are selling more high-price seats，so on popular routes it is not unusual for more than 20 travelers to compete for one or two upgrades. But on routes with fewer business class travelers，free upgrades remain more plentiful.

2. Use miles.

If you're not a frequent traveler but still have some miles to fly，you may be able to use them for an upgrade. Be careful，though，as many airlines now ask not just for miles but also a cash co-pay. One example: on flights to Europe，American Airlines charges 5，000 miles，plus $110，for a one-way upgrade from discounted economy class to business class. For most domestic upgrades，American Airlines wants 15，000 miles plus $ 75.

3. Get lucky.

Sometimes airlines overbook coach（經(jīng)濟(jì)艙），and a few travelers get no seats. Agents try to ensure the airline's most loyal travelers get the nod（被選中）. Agents usually have some flexibility to make sure the plane is full and takes off on time. So it's the easiest way for them to do it-they might upgrade someone else out of order.

4. Save a life.

Flight attendants don't usually upgrade passengers, even when empty seats remain. Doctors and nurses who answer an emergency call are sometimes an exception. If they comfort a passenger, flight attendants might allow them to sit in business or first class for the rest of the flight.

【1】What might be the main topic of the passage?

A. The ways to get upgraded on a plane.

B. How to get on the flight safely and on time.

C. The best ways to get free flight tickets.

D. How to save a life on a plane quickly.

【2】Who can have the chance to get a free upgrade?

A. The person who always obeys the rules on the flight.

B. The person who doesn't have to look after a patient.

C. The person who is a friend of the flight attendants.

D. The person who flies a lot and has a long flying distance.

【3】Why might medical personnel be allowed to sit in business or first class sometimes?

A. Because they would like to talk with flight attendants kindly.

B. Because they want to have a better rest after a long journey.

C. Because they need to treat a passenger who is in emergent condition.

D. Because they are tired of staying with common passengers.

【4】Where can we find the passage?

A. A life guide.B. A travel guide.

C. A shopping guide.D. A pilot guide.

Last Friday our school hold a sports meeting successfully. As a sports lover, I took a active part in it. Of so many kinds of events, I signed up for the 800-meters running race. I took it for granted that I would win the race, because I thought it was my strong point. Beside, I had spent much time making preparations for it. However, much to my surprise, I was just on the point of arriving the finishing line while a boy went ahead of me. The boy, that was running so fast, finally got the first prize. At that moment, I couldn’t help feel a little disappointed. But under the help of my teachers and classmates, I cheered up soon. Although I missed the chance to get the first prize, but I benefited a lot from the experience.

【題目】 The great thing about libraries is that they house all types of books—from mysteries to biographies to dramas—all in one location. The bad thing about libraries is that they house all types of books in one location, and if it’s a location you can’t get to, you’re out of luck. Now, mobile library solutions are appearing quickly around the country to bring books to people who need them.

A few years ago, when the Little Free Libraries Movement launched, more people of all ages could have access to books. Now, more than 15,000 free book stands can be found around the world, bringing books to unexpected places. But many folks simply can’t get to the places where the books are. Bookmobile buses are a good solution, but they can be expensive to fund and to operate.

Books on bikes programs are popping up（出現(xiàn)）in areas where there is a strong bike culture, such as Seattle, or a strong need to bring books to the masses, such as in San Francisco.

The Seattle Public Library’s Books on Bikes program is made up of three bike/trailer combos（復(fù)合）that librarians bring to community events. The trailers are even Wi-Fi enabled so that visitors can sign up for a library card and browse（瀏覽）the library’s card catalog on the spot.

“Seattle has a really strong bike culture so we want to tap into that and provide full service library programs but do it in a way that is quick and smart.” librarian Jared Mills said in an interview.

San Francisco’s program, called Bibliobicicleta, was launched in 2013 by librarian Alicia Tapia. Her trailer can hold about 100 books and attracts readers of all ages and income levels. It’s an independent, donation—based library—ike a Little Free Library, but on wheels.

When asked why she would launch a free library on a bike, Tapia answers, “Why not? Bikes are cool, and can go anywhere.”

【1】According to the writer, the traditional libraries .

A.are popular among the readers

B.are large enough to hold any book

C.are not very convenient to the readers

D.can bring books to people who need them

【2】Which of the following may be the disadvantage of the bookmobile buses?

A.They are full of many travelers.

B.They cost a large amount of money.

C.They hold the limited number of books.

D.They bring books to unexpected places.

【3】The writer mentions Seattle to tell us that .

A.bikes are popular in it

B.visitors can use free Wi-Fi in it

C.it is the same as the city of San Francisco

D.the library card is useful to the visitors

【4】Tapia’s answer suggests that she .

A.enjoys showing off by bike

B.shows impatience to the readers

C.is eager to make the readers happy

D.thinks libraries on bikes are practical
