试题解析

伸长

动物胚胎形态形成运动的一种方式。例如两栖类神经胚期以后,其体躯之所以按头尾方向变得细长,主要是因为躯干尾端,尤其背侧各胚层作头尾方向延长的缘故。此外,两栖类原肠胚原口唇之缩小是带区延长的结果。集中和伸长往往是作为同一过程的两个面而出现的,这在一切脊椎动物头尾轴(前后轴)的形成上起着根本的作用。

Directions:In this part, you will have 5 minutes to go over the passage quickly and answer the questions on the Answer Sheet. For questions 1 - 5, mark  Y ( for YES ) if the statement agrees with the information given in the passage;  N ( for NO ) if the statement contradicts the information given in the passage;  NG ( for NOT GIVEN ) if the information is not given in the passage.  Questions 56 to 60 are based on the following passage.  Do you know how to use a camera properly? First, slide the power switch to the “on” position. The second step is to check that the battery is charged. Check the battery light: if it is red, change the battery. When you are sure the battery is working, you can load the camcorder(便携式摄像放像一体机). Press the eject button to open the compartment and put in a cassette. Do not force the door open. Then, play the test section and watch it in the viewfinder(探视镜) to make sure that the colour, the sound and the focus are correct. The auto exposure adjusts to the light automatically. Next, shoot a test section. Finally, rewind the cassette to the beginning and press the play and the record buttons at the same time to start filming. However, making a film isn’t just about turning your video on and pointing it at something. For professional results, you need to learn some “moviespeak”, the language of film makers. Maybe you can’t make a Hollywood movie but you can at least speak the same language!  Pan  Turn the camera horizontally to take in a scene. Keep your camera slow and steady and don’t turn it more than 90 degrees.  Tilt  Same as pan but moving the camera vertically (i.e. up and down). Same rules apply.  Track  A tracking shot is when you move the camera to follow the action (i.e. when you’re filming someone running).  Zoom  Use the camera lens to change from a close-up shot to a medium shot to a long-distance shot or vice versa. Use it when you want to show an important detail.  Frames  These are the different “photos” that make up a film. There are many kinds. For example, two shot, high angle and low angle.  Statements:  1.It is necessary to check the quality of the battery: if it is broken, change it.  2.Before you start filming, remember first to press the play button, and then to press the record button.  3.The word “moviespeak” refers to the language of movie producers.  4.When you pan, you are required to keep your camera slow and steady and turn it less than 90 degrees.  5.You can take shot up close or a long way away by adjusting the lens.
