Read the following article and select the best answer. Article: Indoor Plants As with any house guests,indoor plants require a certain amount of basic,regular attention if they are going to feel at home. The first consideration when purchasing plants is to make reasonably sure that they are suitable for the condition in which they are going to be housed. A general rule for most plans being brought indoors for the first time is to ensure that they have reasonable temperature of not less than 60 degrees Fahrenheit,a position out of cold air,safe from pets and not exposed to strong sunlight. Plants love company. When plants are growing together,they create an atmosphere of damp around themselves which is far more beneficial than hot dry conditions. A group of plants will also present a more pleasing picture and provide an opportunity for a creative arrangement. There is no secret to this. Just rely on your natural feeling for harmony. Watering and feeding plants are probably the two areas of care that are the least well understood,but,again,if you follow a few simple rules,your plants should do well. Cold Slightly warm water is therefore the answer. It is usually better to pour water on to the soil on the surface of the pot rather than put the water into the pot holder at the bottom. Avoid giving small amount of water at regular intervals- it is much better to wet the soil right through the pot in one go and then to allow it to dry noticeably before giving it a further watering. The majority of indoor plants will be in active growth from March until October,and during this time,the established ones will benefit from regular feeding. This may mean feeding with a weak liquid fertilizer at each watering or at intervals of a week or ten days with fertilizer at a standard strength. It is important,however,to ensure that plants are not fed when growth is inactive,when the soil in the pot is dry,or too soon after the plants has been potted up. Question: What's the benefit of plants growing together? - It provides owners good company. - It helps the air around them slightly wet. - It makes it convenient to look after them. - It allows owners to draw a pleasant picture.
(Answer)
It helps the air around them slightly wet.

Read the following article and select the best answer. Article: The day before yesterday, when Peter's family were having dinner, Father raised an interesting question, "Was there anything in our past that we feel ashamed of, guilty about, or regretted? Maybe we can find ways to say sorry, or take some action to right any wrong doing." This seemed like a very private matter, but Peter thought about it carefully the whole night. Peter remembered an incident from middle school. In his school, there was a worker, Neil Stone, who none of the kids liked. One night, Peter and two of his classmates decided to play a trick on him. They found a can of red paint, and wrote on the school main road in bright red: Neil Stone is a fool! The next day, the whole school saw these words. Within two hours, Neil had Peter and his two classmates in his office. His classmates said that they had done it but Peter lied, denying the truth. No one ever talked about it. This morning, Peter went back to his middle school. Neil Stone is still working there. "Sorry, Neil. Do you still remember what happened ten years ago? I want you to know that I did it." "I knew it!' Neil laughed. They had a good laugh and a lively discussion. Neil's closing words were: "Peter, I always felt bad for you because your classmates got it off their mind, and I knew you were carrying it around all these years. I want to thank you for visiting me... for your sake." Peter knows that no matter how difficult the situation is, it is never too late to clear up the past and make a fresh start. Question: What color were the words "Neil Stone is a fool!"? - Dark blue - Light green. - Pure white. - Bright red.

Read the following article and select the best answer. Article: He is not just a classical music superstar. He is a global superstar. Only 27 years old, the Chinese pianist Lang Lang has become an inspiration to tens of millions around the world. Among his dazzling long list of titles, Lang considered UNICEF goodwill ambassador the most special one. "Being a UNICEF goodwill ambassador is the best decision I have made and will definitely be the best experience in my life," Lang said in a recent interview with Xinhua at the UN headquarters in New York. "I love children very much, and playing piano for them is my favorite," Lang said, beaming with delight. Named this year by Time magazine as one of the 100 World's Most Influential People, the pianist said he hoped music could "bring children happiness and enlighten their life." Three months after his nomination , Lang went to Tanzania with the UNICEF team to visit children threatened by malaria and AIDS. Although the southeastern African country's underdevelopment and harsh living conditions surprised Lang who landed the continent for the first time, he was touched by local children's passion for music. "Most of the kids had never seen a piano before," Lang said. "When I played Chopin's nocturne or waltz to them, those who were too shy to talk to me suddenly became active and began to share with me about their dreams. How amazing it is!" "Music can bring hopes to the kids and open their mind," he said. Following his visit to Africa, Lang began to organize fundraising concerts for children. Now it has become his routine to do 15 to 20 fundraising concerts every year. Except for his efforts on fundraising, Lang also established his own international music foundation last year to assist young talents to play piano. So far Lang has chosen five children from the United States and Germany, providing them with scholarships and opportunities to perform at world-class music halls, he said. In December, he will start the selection in China where he would like to "focus more on physically challenged kids, like blind kids."
