The Grinch (2000)This is a
2、 Christmas mustwatch and one of Jim Carreys best performances. It was also originally a nursery tale book written by Dr Seuss. Its the story of a green monster who wants to ruin Christmas but in the end discovers the power of love and generosity. I promise its a great film with plenty of laughs alon
3、g the way.Love Actually (2003)While this is not a personal favourite of mine, people in the UK absolutely love this film. It has many featuring actors and actresses. It might be a little difficult to follow as there are complex plots, so I recommend watching a translated version. However, the heartw
4、arming elements of the film make it worth watching.Home Alone (1990)This amusing masterwork is one of my favourite films of all time. It tells the story of a boy, Kevin, who is left alone in his house when his large family forgets to take him on vacation with them. While other family members are awa

9、Rawat teaches AI at the University of Southern Californias(USC) Clinical Science Center in Los Angeles. He is part of a team of scientists who are researching how AI and machine learning can more easily recognize cancerous growths in the breast.Rawat provides information about cancerous cells to a c
10、omputer. He says this data helps the machine learn. He says, “You can put the data into them and they will learn the patterns and the pattern recognition thats important for making decisions.”David Agus, another USC researcher, believes that machines are not going to take the place of doctors. He sa
11、ys, “Computers will not treat patients, but they will help make certain decisions and look for things that the human brain cant recognize.”Once a confirmed cancerous growth is removed, doctors still have to treat the patient to reduce the risk of cancer returning. The form of treatment depends on th
12、e kind of cancer. Currently, researchers take a thin piece of tissue, put it on a small piece of glass and add color to it to better see the cells.That process could take days or even longer. Scientists say artificial intelligence can do something better than just count cells. Through machine learni
13、ng, it can recognize complex patterns, or structures, and learn how the cells are organized. The hope is that machines will soon be able to make a quick identification of cancer that is free of human mistakes.Agus says that with the computing power the process could be done for almost no cost. He ad
14、ds that having a large amount of information about patients is important for a machine to effectively do its job in medicine.USC researchers are now only studying breast cancer. But doctors predict artificial intelligence will one day make a difference in all forms of cancer.4What are Rawat and his

18、st Cancer Will Be Found Soon CArtificial Intelligence May Make Better DoctorsDScientists Are Doing Some Research on Breast Cancer CThe first hamburger created by scientists in a lab has been recently presented in London. The burger, which cost over 300,000 dollars to grow, comes from stem cells(干细胞)
19、 that were taken out of the shoulder of a cow.It took food scientists three months to raise 20,000 tiny pieces of meat to create one single hamburger. Stem cells were reproduced and, over a period of time, created their own muscles. Mark Post，who is a scientist at a Dutch university and responsible
20、for the project, has been researching this method for a long time. He says that the job was a difficult one because it was important to keep the cells healthy and not let any pollution get into them during the whole process.Food experts who tasted the new hamburger said that it felt like meat but it
21、 was without fat, which normally changes the taste. Biting into it felt like a real burger, but it wasnt as tasty because salt and pepper were missing.The experiment showed that creating food in a lab is a possible solution (解决办法) for the worlds food problems. Large quantities of meat could one day
22、be made without raising millions of animals around the world. Those who welcome such a method say that we cannot produce enough meat in the future and such a new method could be an alternative. But it will be a long time before consumers get to taste such a new hamburger at McDonalds or elsewhere. I
23、t would have to be made much cheaper and the time it takes to grow such a hamburger would have to be greatly reduced. Scientists are hoping to get food companies to spend money on this new technology. But many question marks remain. Taste, which was put aside in the first prototype(原型), must be impr
24、oved to give a consumer the taste of real meat.Meat grown by people could be a way of producing enough food for our growing population without killing animals. In addition, reducing livestock (家畜) reduces greenhouse gases. Animals produce about double the amount that we humans create. By the middle
25、of the century the human population is expected to rise to 9 billion and the demand for food, especially meat, will rise.8The first hamburger comes from stem cells that were taken out of _.Athe leg of a cow Bthe shoulder of a cowCthe neck of a cow Dthe tail of a cow9Which of the following didnt make
26、 the food experts satisfied about the hamburger?AIts taste.BIts color.CIts shape.DIts nutrition.10What used to trouble Mark Post most in the lab was that _.Ait was very difficult to reproduce stem cells from a cowBthe stem cells must be kept clean and healthy all the timeCit would take him a long ti
27、me to collect enough stem cellsDthe meat in the hamburger didnt have any fat in it11According to the passage, what will happen if Marks method is widely used?AThere will be fewer diseases among animals.BAnimals can grow much faster and bigger than ever.CPeople will be able to eat meat with different
28、 tastes.DGreenhouse gases from animals will be greatly reduced. DWeve been covering standing desks for a long time now because experts agree that sitting all day is killing us. We want to be productive while also keeping our bodies healthy. Over the years, there have been several solutions to this f
29、rom fixed standing desks to adjustable ones, portable desks to ones that change into shelves.However, the most hightech and elegant solution has to be this new smart desk called the Stir Kinetic Desk. The desk learns your daily behavior and moves between a sitting and standing height regularly throu
30、ghout the day to keep you moving without interrupting your work flow.You can program specific sitting and standing intervals or let the desk set the schedule. If you tend to sit while returning emails in the morning, but always want to stand during that afternoon conference call, the desk will learn
31、 those regular habits and adjust the schedule to fit them. Of course, the desk can always be manually lowered or raised by using the touch screen on the lower left corner of the desk.When switching positions, the desk gently dips and rises to let you know that a change is coming up. If youre not rea
32、dy to switch positions at that time, you can tap the touch screen to stay sitting or standing for a while longer.The builtin touch screen also keeps track of your daily sitting and standing times and tells you how many calories youve burned. You can even set goals for how long or how often you want
33、to stand. The desk also works with fitness devices like the Fitbit to track your movements.All of that smart technology doesnt come cheap though. The M1 desk, which is the everyday model, runs a steep $2,990, while the more executive model with added features, the F1, goes for $4,190.While expensive
34、, its worth that thinking of how much time we spend at our desks. Much like a good mattress (床垫), a good desk that works with you is worth the investment. Hopefully in a few years these smart, integrated desks will be more common and less expensive.12The Stir Kinetic Desk has been designed to _.Ahel
35、p users with their workBkeep users moving all the timeCget users to exercise while workingDremind users of their working schedule13Which is the feature of the touch screen of the desk?AIt can tell users when to change positions.BIt can track users changes of positions.CIt can keep users in a fixed p

37、a desk is rewarding.BWe should get such a desk as soon as possible.CIt wont be long before the desk is widely used.DDesks play a very important role in our daily life.第二节（共5小题；每小题2分，满分10分）根据短文内容。从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余项。It was the 2015 “super storm” in New South Wales that restored my faith
