Growing up，I wanted to be just like my mom.She was kind.People always seemed to feel comfortable in her presence.For years，she was a volunteer in our community.I loved going to the local nursing home with her where she taught a ceramic class.

On one summer day，Mama told me to get changed and meet her at the car.

I had planned to spend the day at the lake with friends.Why did she have to ruin everything？I

imagined the cool lake water.Irritated，I climbed into the car and slammed the door shut.We sat in silence.I was too upset to make a conversation.

“Tasha，would you like to know where we are going？” Mama asked calmly.

“No，” I said.

“We are going to volunteer at a children’s shelter today.I have been there before and I think it would benefit you，” she explained.

When we reached the shelter，Mama rang the doorbell.Moments later，we were greeted by a woman.She led us to the front room where all of the children were playing.I noticed a baby whose body was scarred with i ron marks.I was told it was because she wouldn’t stop crying.The majority of the children had noticeable physical scars.Others hid their emotional wounds.

As I took in my surroundings，I felt a gentle tug on my shirt.I looked down to see a little girl looki ng up at me.“Hi.You want to play dolls with me？” she asked.I looked over at Mama for reinforcement.She smiled and nodded.I turned back and said，“Sure.” Her tiny hand reached up and held mine，as if to comfort me.

My mom taught me a valuable lesson that summer.I returned to the shelter with her several times.During those visits，some of the children shared their troubled pasts with me and I learned to be grateful for what I had.Today as I strive to instill(逐渐灌输) these values in my own child，I reflect back to that experience.It was a time that I will never forget.

When I was in the seventh grade，I was a candy striper(义工) at a local hospital in my town.I volunteered(自愿做) about 30 to 40 hours a week during the summer.

Most of the time I spent there was with Mr.Gillespie.He never had any visitors，and nobody seemed to care about his condition.I spent many days there holding his hand and talking to him，helping with anything that needed to be done.He became a close friend of mine，even though he responded with only an occasional squeeze(紧握) of my hand.Mr.Gillespie was in a coma(昏迷).

I left for a week for a vacation with my parents，and when I came back，Mr.Gillespie was gone.I didn’t have the courage to ask any of the nurses where he was，for fear they might tell me he had died.So with many questions unanswered，I continued to volunteer there through my eighth-grade year.

Several years later，when I was a junior in high school，I was at the gas station when I noticed a familiar face.When I realized who it was，my eyes filled with tears.He was alive！I got up the nerve to ask him if he was Mr.Gillespie，and if he had been in a hospital about five years ago.With an uncertain look on his face，he replied yes.I explained how I knew him，and that I had spent many hours talking to him in the hospital.His eyes welled up with tears，and he gave me the warmest hug I had ever received.

He began to tell me how，as he lay there comatose(昏睡的)，he could hear me talking to him and could feel me holding his hand the whole time.He thought it was an angel(天使)，who was there with him.Mr.Gillespie firmly believed that it was my voice and touch that had kept him alive.Then

he told me about his life.We exchanged a hug，said our good-byes and went our separate ways.

Although I haven’t seen him since，he fills my heart with joy every day.I know that I made a difference between his life and his death.As importantly，he has made a great difference in my life.I will never forget him and what he did for me：He made me an angel.

Animals are a favorite subject of many photographers.Cats，dogs，and other pets top the list，followed by zoo animals.However，because it’s hard to get them to sit still and “perform on

command”，some professional photographers refuse to photograph pets.

One way to get a nice picture of a cat or a dog is to hold some delicious food above the camera.The animal’s longing look toward the food will be captured(捕捉) by the camera，but the food won’t appear in the picture because it’s out of the camera’s range.When you show the picture to your friends afterwards，they’ll be impressed by your pet’s loving expression.

If you are using fast film，you can take some good，quick shots of a pet by simply snapping(抓拍) a picture right after calling its name.You’ll get a different expression from your pet using this technique.Depending on your pet’s moo d，the picture will capture an interested，curious expression or possibly a look of annoyance，especially if you’ve awakened it from a nap.

Taking pictures of zoo animals requires a little more patience.After all，you can’t wake up a lion！You may have to wait for a while until the animal does something interesting or moves into a position for you to get a good shot.When photographing zoo animals，don’t get too close to the cages，and never tap on the glass or throw things between the bars of a cage；concentrate on shooting some good pictures，and always respect the animals you are photographing.

12.Why do some professional photographers refuse to take pictures of pets?

A.Pets may not follow orders.

B.Pets don’t want to be bothered.

C.Pets may not like photographers.

D.Pets seldom change their expressions.

13.What is the use of food in taking pictures of a pet?

A.To capture a nice look.

B.To create a special atmosphere.

C.To prevent the animal from getting hungry.

D.To keep the pet from looking at the camera.

14.The unde rlined word “annoyance” in Paragraph 3 is closest in meaning to “”.

A.joy

B.pain

C.anger

D.interest

15.In what way is photographing zoo animals different from photographing pets?

A.You need to have fast film.

B.You need special equipment.

C.You need to stay close to the animals.

D.You need more time to watch and wait.

Respect them more and cherish these moments.You can use these moments to learn from them，preparing yourself for when you’re off on your own.It’s OK to get angry but angry actions don’t help you or your parents.Act calmly，cool off，write down your feelings，or talk to a friend. 17 Obey their requests.It will make your attitude better and earn you more respect from them.It may seem like you are going through hell(地狱) when you don’t get what you want or you have to clean.However，you had better remember they keep a roof over your head when it’s cold，raining，snowing，or too hot.Understand that parents are human beings and make mistakes. 18 Since you can forgive your friends，why not forgive your parents?

Keep company with them.Do things with your parents like watching TV，or go somewhere with them. 19 Listen to their old stories and learn from them.You will find they are your teachers in this way or another.

Some people simply may not be able to love their parents. 20 Seek help if you are being abused(虐待) in any way.Parents do not have a right to harm you.

A.Forgiveness is the key.

B.Tell them you love them every morning.

C.Parents will in turn express their love to you.

A．filming B．being filmed C．to be filmed D．having been filmed 答案 D 解析句意为：在七年前就拍摄完成的电影《无问西东》于2018年1月12日上映。分析句子结构可知，空处应填非谓语动词；又因为The new movie Fore v er Young与动词film之间为被动关系，且根据句中的时间状语“seven years ago”可知，非谓语动词所表示的动作发生在谓语动词released所表示的动作之前，故空处应用having been filmed。 2．We took a taxi to the airport.Otherwise we late for our flight this morning. A．were B．had been C．would be D．would have been 答案 D 解析句意为：我们乘坐出租车去的机场，否则我们就赶不上今天上午的飞机了。根据句意尤其是句中的“Otherwise”一词可知，空处表示与过去事实相反的假设，故谓语动词应用would have done结构。 3．It is reported that house prices are always higher famous schools lie than other places.

B When I was a boy, our extended immigrant family would sometimes gather at m y aunt’s tiny house over the summer. Relatives from all over the country would come in to visit. The adults would crowd together in the living room to talk and catch up on each other’s lives. And the kids would be sent out into the front yard to play when dinner was slowly cooked for all of us. Those were the days before video games, smart phones, and motorized toys, so we often ended up playing an old game. I remember one of those moments especially. As I was the youngest and smallest of all the kids there, I got caught first and couldn’t catch anyone else. My brothers and cousins were all too fast for me, and I grew more and more frustrated. I finally fell my face first into the dirt. I got up with tears forming in my eyes. Then I saw one of my female cousins Susan standing there. She started to run but was going much slower than before. I easily caught up and seized her. Then she turned to me, smiled, and said, I’m it! You’d better run! Iran off laughing with glee while she turned and started to chase others. Now I see how her act of kindness that day saved me from sadness and returned me to joy. It didn’t matter that we hardly ever saw each other. I know we are family and she
