Donating books for poor children
A voluntary activity is now being held in our school, aimed at collecting books for children in poor areas in China.
The activity “For the Children”was advocated by a retired teacher, Mr. Sun, who is now teaching in a small middle school in a remote village in Yu’nan. According to him, students there are eager to learn, but are so poor that they can’t afford books. Mr Sun said we can donate books to help build a library for them.
So at lunchtime this week, students in our school gather at the school hall to donate their books which are then sorted, packed and delivered to Yu’nan by mail. Children’s books, novels, science fictions and comic strips are quite popular. I gave away dozens of my favorite books and hoped students there would like them.
It is amazing to help build a library for people in need! Children there will have plenty of books to read as well as a better learning environment. A little more effort, and we can make a big difference! (163 words)

One possible version:
Recently my class took part in the social practice organized by our school, in which we conducted a survey among kids aged 5-14 about their extra-curriculum activities. The results are as follows.
As is illustrated in the chart, both boys and girls have a strong preference for watching TV or videos with the percentage ranking first at 100%. More boys than girls enjoy skateboarding or rollerblading, bike riding and electronic or computer games as leisure activities, each accounting for nearly 40% , 70% and 80%. However, girls outnumber boys by almost 20% when it comes to art and craft.
We can draw a conclusion from this survey that according to the data, passive pursuits are far more popular nowadays than active ones and that those who opt for creative pastimes are in the minority.
In my opinion, since the addiction to watching TV or videos or playing computer games is likely to do harm to children’s health, parents should be responsible for limiting the children’s time spent on passive leisure activities. In addition, more emphasis should be attached to activities that can encourage children to develop their creativity and build up physical health. (165 words)

The over exploitation of World Heritage sites has raised public concern. As is shown in the cartoon, the World Heritage sites are overcrowded with large groups of tourists pushing, taking photos, or even spitting, smoking and scribbling everywhere, which has caused great damage to these historic buildings.
One of the contributing factors of this phenomenon is that the local government is pushing too hard for the development of tourism, ignoring damage prevention and educational function of the sites. Moreover, some self-centered tourists are uncivilized in public places, ignorant of the historical and cultural value of the sites.
From my point of view, the original purpose of setting up World Heritage sites is to help preserve history so that people will be able to enjoy it for generations to come. I suggest both the government and the public should be aware that the best form of conservation is the prevention of damage and committees should be established to undertake important educational work.

河南省顶级名校2015届5月热身模拟英语试卷（2） （本试卷共120分，考试时间100分钟） 第一卷 第一部分听力部分（略） 第二部分阅读理解(共两节，满分40分) 第一节（共15小题；每小题2分，满分30分） 阅读下列短文，从每题所给的四个选项(A, B, C和D)中，选出最佳选项.并且在答题卷上将该项涂黑。 A My grandparents were married for over half a century, and played their own special game the time they had met each other. The goal of their game was to write the word “shmily” in a surprise place for the other to find. They took turns leaving “shmily” around the ho use, and as soon as one of them discovered it, it was their turn to hide it once more. They dragged “shmily” with their fingers through the sugar and flour containers to await whoever was preparing the next meal. “Shmily” was written in the steam left on t he mirror after a hot shower, where it would reappear bath after bath. There was no end to the places where “shmily” would pop up. Little notes with “shmily” were found on car seats, or taped to steering wheels. The notes were put inside shoes and left und er pillows. “Shmily” was written in the dust upon the mantel（壁炉架）and traced in the ashes of the fireplace. This mysterious word was as much a part of my grandparents’ house as the furniture. It took me a long time before I was able to fully appreciate my grandparents’ game. Skepticism has kept me from believing in true love—one that is pure and enduring (持久的). However, I never doubted my grandparents’ relationship. It was based on passionate affection which not everyone is lucky enough to experience. But there was a dark cloud in my grandparents’ life: my grandmoth er had breast cancer. The disease had first appeared ten years earlier. As always, Grandpa was with her every step of the way. He comforted her in their yellow room, painted that way so that she could always be surrounded by sunshine, even when she was too sick to go outside. But my grandmother grew steadily weaker until, finally, she could not leave the house any more. Then one day, what we all dreaded finally happened. Grandma was gone. “Shmily.” It was written in yellow on the pink ribbons of my grandmother’s funeral bouquet (花束). As the crowd thinned and the last mourners turned to leave, Grandpa stepped up to my grandmother’s coffin and, taking a shaky breath, he began to sing to her. Through his tears and grief, the song came: S-h-m-i-l-y: See How Much I Love You. 21. The first paragraph is mainly about ________. A.what the word “shmily” means B.how the author’s grandparents played their special game C.how the author appreciated her grandparents’ game D.how the author’s grandparents cared for each other 22. The underlined phrase “pop up” in Paragraph 1 means ________. A. appear B. change C. survive D. work
