Once there were two brothers. They were very good to each other. They were half brothers because the elder brother's mother was dead, and then his father married again. The stepmother was not kind to the elder brother, but the younger brother loved him and often helped him. One day, the mother gave each of the brothers a box of seeds and enough food for a few days. She said to them, "Take them. Go and plant them. One of you must plant them on the east hill, and the other on the west hill. Don't come back if the seeds don't come out. " The mother gave very bad seeds to the elder brother, but the two brothers didn't know this, and set out the next morning. When they came to a bridge, they sat down to rest. After that, they got up to say good-bye to each other, but they took the wrong boxes of seeds! Ten days later, the elder brother's seeds began to grow and he came back. But the younger brother did not return home because his seeds didn't grow. At last, he died on the hill. ,. (10) In fact the mother wanted _ A) the two brothers to plant trees B) the two brothers to work hard C) the elder brother to die D) the younger brother to die

The colour systems used by scientists and artists are completely different. An artist will mix blue and yellow paint to get a shade of green; a scientist will mix green and red light to create yellow. The printed page in a magazine is yet another system. Scientists recognize the light primaries are red, green and blue. When mixed, red and green light rays produce yellow, blue and green produce cyan, red and blue produce magenta. Red, green and blue mix to create white (light). This colour model is used in computer monitors, television sets and theatre. Most artists recognize red, yellow and blue as the three basic primary colours. These primaries are the pure colours which cannot be created by mixing any other colours. In the print industry, cyan, magenta, yellow and black are used as the primary colours. When you mix all the colours, the result is gray. Which of the following is NOT true? A) Red, green and blue are used in television sets. B) If scientists want to get white, they will mix red, yellow and blue. C) Most artists think red, yellow and blue are the pure colours. D) In the print industry, if you mix all the colours, you will get gray.

Q: It is easy for us to tell who our family members are, but do plants recognize their own family? Some do, scientists say, according to a report by Science News in early 2010. Guillermo P. Murphy and Susan Dudley are two plant scientists from McMaster University in Hamilton, Canada. They did a few experiments with Jewelweeds, a kind of flower that grows in wet, shady spots. They found that the flowers seem to know their own flower family. In their experiments, Murphy and Dudley planted jewelweeds in pots with either _ or strangers. When jewelweeds were planted in pots with strangers, the plants started to grow more leaves than if they had been planted alone. This response suggests that plants are competing with strangers for sunlight, since a plant with more leaves can receive more light and make more food. Jewelweeds usually grow in the shade, where sunlight is not enough. When jewelweed seedlings were planted with siblings, they grew a few more branches than they usually would if they were alone - but they did not start growing lots of extra leaves. This behavior suggests the plants are more likely to share resources, rather than compete. According to the Science News report, Jewelweeds are not the first plants that plant scientists have studied for family recognition. In 2007, Dudley and her team studied the Great Lakes sea rocket, a plant that grows on the beach - where it may be hard to get fresh water. In that experiment, the scientists found that when sea rockets were planted with siblings, they tolerated each other. But when they were planted with strangers, the sea rockets reacted by working extra hard to grow lots of roots. Dudley says this just because sea rockets, on the beach, get plenty of sun but struggle for water - so when they're threatened, they compete for water. Jewelweeds have plenty of water but have to compete for sunshine, so they grow more leaves. In the text, the writer mentioned the experiments of Jewelweeds to _ . A) make a comparison B) introduce a topic C) describe a pretty flower D) build a new theory

Question: The landmark success of Tu Youyou, the first Chinese woman to win a Nobel prize in science, has aroused great national pride and hopes on the future of traditional Chinese medicine (TCM). Tu, born in 1930, shared the 2015 Nobel Prize for Physiology or Medicine with Irish-born William Campbell and Japan's Satoshi Omura for her discoveries against malaria . She discovered Artemisinin , a drug that has greatly reduced the death number for patients suffering from malaria. "Artemisinin is a gift for the world people from the traditional Chinese medicine. It is of great importance for curing malaria and other diseases and for protecting the health of the world people," Tu said in Beijing. " The discovery of Artemisinin is a successful example of collective research on traditional Chinese medicine. The prize winning is an honor for China's science cause and traditional Chinese medicine." "Tu's winning the Nobel Prize shows China's great progress in science and technology. It also shows China's growing strength and rising international standing," Premier Li Keqiang said in a letter Monday evening. What is the best title of the passage? A) Cheers, hopes as Chinese pharmacologist wins Nobel prize. B) William Campbell, Satoshi Omura and Youyou Tu win Nobel prize C) The discovery of Artemisinin is a very successful example of research. D) The breaking news makes at least tens of thousands of people excited.
