Now they are important helpers in real life. Zhongshan Hospital is the only hospital in China to have introduced a robotic system from abroad to assist with heart surgery. More than 30 heart disease patients have had operations with robotic assistance. All have reported good results. The technology, developed by the United States, has only been in use since the late 1990s. Zhongshan Hospital bought it in 2000. During surgery, a robotic arm holds the endoscope under the direction of the surgeon, who controls the surgical tools. The surgery team can be reduced from four to two people. "Because it is a machine, the robotic arm is more exact and can improve safety,"said Zhao Qiang, a surgeon at Zhong-shan Hospital. "It won’t shake or make a big move that hurts the patient. It also remembers the important spots and quickly goes exactly where I want it to."As the system is still in its infancy, doctors are only using it on selected patients, generally those who are younger and stronger. The system still needs to be improved. Experts believe that robotic assistance in surgery is the future of medicine, since most operations only need small cuts. Doctors only need to make three small cuts in the chest, allowing for the entrance of the endoscope and two surgical tools.After that, they can do the operation freely. Scientists in the US have now developed a more advanced robotic system. It has three arms and takes the lead surgeon’s place. The s urgeon doesn’t need to use a knife to do the operation himself. Instead, he can look at the screen and give orders to control the robot. The hospital plans to buy one within three years.Notes:1. surgery n.外科手术2. endoscope n.内窥镜3. surgeon n.外科医生词数144 处理时间2' 24''1.

A fruit that can be found in countries all over the world. A fruit that everyone must have in summer, that makes us feel more comfortable and cools us down. A fruit that tastes great. That is my favorite fruit, the watermelon.A watermelon normally has a round shape with hard green rind and sweet juicy pulp. Every time I start eating one, I want to have more. It tastes sweet. It smells fresh. Inside the watermelon, the flesh is normally red or yellow with a sweet smell that attracts me to eat it. Watermelon is very healthy for people to eat, because watermelon is an excellent source of vitamin C and vitamin A. Therefore my parents love to buy watermelons for me. In summer, I can eat a huge one every day, but there’s a very bad disadvantage —I can’t stop going to the toilet! Watermelon is 92 percent water by weight, the highest percentage of any fruit! That’s why it causes me to go to the toilet so often.To eat a watermelon, I will first use a knife and cut it in half. After that I will take a big spoon and start digging into it. It’s quite fun!No matter how often I eat watermelon, no matter how common it appears on earth, I always find it the most delicious fruit. That is my favorite fruit: watermelon, the best fruit in the world.Notes:1. rind /raInd/ n.(某些水果的)厚皮,外壳2. juicy /5dVu:si/ adj.多汁的3. pulp /pQlp/ n.果肉。
