2.3 Nomination Structures are widely used. Compare the following two sentences Archimedes first discovered the principle that water is displaced by solid bodies. Archimedes first discovered the principle of displacement(阿基米德最 先发现固体排水的原理. ) 第二句中of displacement of water by solid bodies 系名词化结构,一方面 简化了同位语从句,另一方面强调displacement 这一事实. 2.4 Widely use of Long and Complexity sentences E.g Anyone can watch an apple fall and ruminate about a force of gravity. It took the genius of Newton to leap from there to the idea that it was the same force that causedthe moon to drop from its natural motion in a straight line , to calculate at once the amount by which it dropped and from that to infer the inverse - square law ; in short , to leap fromterrestrial gravity to a simple and universal law of gravitation.

• Although I love movies, I’ve found that there are drawbacks to moviegoing. One problem is just the inconvenience of it all. To get to the theater, I have to drive for at least fifteen minutes, or more if traffic is bad. It can take forever to find a parking spot, and then I have to walk across a huge parking lot to the theater. There I encounter long lines, sold-out to the floor because of other people’s spilled snacks. Another problem is my lack of self-control at the theater. I often stuff myself with unhealthy calorie-laden snacks. My choice might include a bucket of popcorn, a box of Milk Duds, a giant soda, or all three. The worst problem is some of the other moviegoers. Kids run up and down the aisle. Teenagers laugh and cough and burp, and talk to one another. All in all, I could rather stay home and wait to see the latest movie hits on cable TV in the comfort of my own living room.

关于科技进步的英语_ppt演讲
I need a more advanced world. My major reason is because when you have advanced technologies, life is much easier as robots and machines would take over your daily life chores(零星工作 ) . For example, daily life chores might be serving your breakfast, cutting your grass, or cleaning your room. With robots and machines doing one’s chores ，one has time to relax. Another reason is because unlike humans, robots and machines do not make mistakes when programmed correctly. They always finish tasks perfectly so you won’t have to worry about making a mistake and getting trouble.
Today, we can’t imagine ourselves without technological advances such as cars, microwaves, cell phones, computers, and televisions. However, technology won’t stop here, but develop further. A few advantages of upgraded technology are that one can save time and money and life will be made easier as a result of not having to do all the hard labor.
