Passage 1
According to experts, the advantage of modified food is that it helps in preventing the occurrence of allergies and also has a long shelf life. However, a major portion of the population is against the consumption of genetically modified food and is concerned about its disadvantages. I£ you are also confused about the consumption of genetically modified food, read through the pros and cons given below and decide for yourself.
Advantages of Genetically Modified Foods
, One of the most prominent advantages of genetically modified food is that it helps in controlling the occurrence of certain diseases. Certain foods cause allergy to people. Their genetic modification alters the DNA system of these foods» thereby making them non-allergic.
•Another major advantage of such type of foods is that they grow faster than their traditionally grown counterparts. As a result, there is greater productivity and more food.
•A person need not bother about any additional costs, such as buying chemicals and pesticides, when it comes to genetically engineered food. The food is naturally pest-resistant.
•Farming these foods can be a great way to fight world hunger. Since these crops grow faster or more effectively, increased production would help countries wherein crops may not normally prosper because of less than desirable environmental conditions.
•The increased shelf life of these food products helps in reducing the quantity of rotten food.
Disadvantages of Genetically Modified Foods
, The biggest disadvantage of genetically modified food is that they have harmful effects on the human body. The consumption of these genetically engineered foods can lead to development of diseases that are immune to antibiotics.
•Chances of developing cancer are high in people who regularly consume engineered food.
•Since it is an unnatural way of producing foods, there is an increased health hazard such as allergens, transfer of antibiotic resistance markers and unknown effects.
•Since the production of engineered food involves infusing animal genes in the crops and tampering with nature, it might not be good for consumption in the long run.
21.How does genetically modified food control the occurrence of certain diseases?
A.By cross-pollinating.
B.By conventional crossbreeding.
C.By altering the DNA system of these foods.
22.Do farmers need to buy any chemicals and pesticides if they plant genetically modified food?
A.Yes, they need to. Because the food is not resist to pests.
B.No, they don’t need to. Because the food is naturally pest-resistant.
C.No, they don’t need to. Because the chemicals and pesticides are provided by the government.
23.Which statement is not the advantage of genetically modified food?
A.It may have harmful effects on human body.
B.Genetically modified food grows faster than their traditionally grown counterparts.
C.Farming genetically modified food can help fight world hunger.
24.What would happen to a person if he regularly consume genetically modified food?
A.He would get cold.
B.He would lose some weight.
C.He would have cancer.
25.Which of the following would be the best title for this passage?
A.Can Genetically Modified Foods Combat World Hunger?
B.Genetically Modified Mood： Our Answer Is No.
C.Genetically Modified Foods： Pros And Cons
26—30题:请根据短文内容判断给出的语句是否正确，正确的写“T”,错误的写“F”，并将答案 写在答题纸上。
Passage 2
Engineers who build and program robots have fascinating jobs. These researchers tinker （修补）with machines in the lab and write computer software to control these devices. “They’re the best toys out there,” says Howie Choset at Carnegie Mellon University in Pittsburgh. Choset is a roboticist, a person who designs, builds or programs robots.
When Choset was a kid, he was interested in anything that moved-cars, trains, animals. He put motors on Tinkertoy cars to make them move. Later, in high school? he built mobile robots similar to small cars.
Hoping to continue working on robots, he studied computer science in college. But when he got to graduate school at the California Institute of Technology in Pasadena, Choset? s labmates were working on something even cooler than remotely controlled cars： robotic snakes. Some robots can move only forward, backward, left and right. But snakes can twist （扭曲）in many directions and travel over a lot of different types of terrain （地形）.Snakes are far more interesting than the cars,” Choset concluded.
After he started working at Carnegie Mellon, Choset and his colleagues there began developing their own snake robots. Choset? s team programmed robots to perform the same movements as real snakes, such as sliding and inching forward. The robots also moved in ways that snakes usually don’t, such as rolling.
Choset?s snake robots could crawl （爬行）through the grass, swim in a pond and even climb a flagpole.
But Choset wondered if his snakes might be useful for medicine as well. For some heart surgeries, the doctor has to open a patient ?s chest, cutting through the breastbone. Recovering from these surgeries can be very painful. What if the doctor could perform the operation by instead making a small hole in the body and sending in a thin robotic snake?
Choset teamed up with Marco Zenati, a heart surgeon now at Harvard Medical School? to investigate the idea. Zenati practiced using the robot on a plastic model of the chest and they tested the robot in pigs.
A company called Medrobotics in Boston is now adapting the technology to surgeries on people.
Even after 15 years of working with his team’s creations? “I still don’t get bored of watching the motion of my robots,Choset says.
26.Choset began to build robots in high school.
27.Snake robots could move in only four directions.
28.Choset didn’t begin developing his own snake robots until he started working at
Carnegie Mellon. ‘
29.Zenati tested the robot on people after using it in pigs.
30.The robotic technology for surgeries on people has brought a handsome profit to Medrobotics.

The chart below illustrates reading preference based on a survey of 200 college students in 2016 in China. Write a survey report based on the given information. Your report should include：
(1)The subjects and respondents of the investigation.
(2)Analysis of investigation result.
(3)Your opinion or suggestions about college students^ reading.
Recently we have conducted a survey among 200 college students to find out their reading preference. As can be seen in the pie chart, 27 % o£ the surveyed said they spent most of their time reading magazines and books for entertainment. What ranks the’ second are books of literature and applied technology) and they each account for 25 %・ The percentage decreases to 15 % as to students who prefer to read books relevant to their majors, while only 8 % tend to read popular science books during their spare time.
It should be noted that books of literature, applied technology, and entertaining books like magazines are main interests of college students. That ‘ s because these kinds of books are fun and easy to read; what ‘ s more? they bring students some cutting-edge information regarding books of applied technology. The percentage of students who like to read professional books is relatively lower may be due to the reason, that these books are hard to understand and time-consuming.
To sum up, the data reveals a serious problem that college students ‘ reading preference stays at a relatively shallow level since the percentage of reading magazines exceeds that of literature and professional books. We thus suggest that colorful reading activities like recommending great books be carried out to help students develop capabilities of appreciation and criticism.
