Toy Story: the first all-CGI film
When we think of modern films, we often think of CGI—computer-generated imagery. CGI uses computers to create images that appear on screen. In its early days, CGI struggled to show details like skin and hair, so it was hard to make real-looking human characters. However, CGI was much better at showing hard surfaces such as wood, plastic and metal—things like toys. So, it is no surprise that the world’s first fully CGI feature-length film was *Toy Story* (1995).
Before *Toy Story*, animated films were made using plastic sheets. One minute of animation could require 1,440 of these sheets, and many of them had to be painted by hand. This was so slow that even one minute of a simple film could take days to finish. *Toy Story* changed all of this. The film with over 77 minutes of pure CGI was made on 117 computers and took over 800,000 machine hours. Pixar was only able to make about 30 seconds of the film a day. But this was still much faster than making the film by hand.
Toy Story* was a huge success, earning over $375 million worldwide at the box office. But its biggest achievement was not the money it made. The quality of the animation was so high that the toys felt real and full of life. *Toy Story* showed that good CGI could bring films to life, and the film industry has never been the same since.1 What do film-makers use CGI to create?a Sounds.b Pictures.c Plots.2 Why were toys chosen as the subject of the first all-CGI film?a Because toys were popular with children.b Because toys do not have skin and hair.c Because CGI was good at showing things made from wood, plastic and metal.3 How many plastic sheets are needed to make 30 seconds of an animated film in the old way?a 117.b 720.c 1,440.4 From the passage, why might film-makers want to use CGI instead of traditional animation?a It is quicker.b It is cheaper.c It is more artistic.5 Why has *Toy Story* had such a great influence?a Because it was made more quickly than other animated films.b Because it earned over $375 million.
c Because it showed that CGI could bring a film to life.
答案：1. b 2. c 3. b 4. a 5. c
解析：
1. 定位原文第一段"CGI uses computers to create images that appear on screen."，其中images意为图像、画面，对应选项b的Pictures，a声音、c剧情均不符合原文表述。
2. 定位原文第一段"However, CGI was much better at showing hard surfaces such as wood, plastic and metal—things like toys."，可知早期CGI更擅长呈现木头、塑料、金属这类材质的物体，玩具正好符合这个特点，因此选c，a的玩具受孩子欢迎、b的玩具没有皮肤头发都不是原文给出的原因。
3. 定位原文第二段"One minute of animation could require 1,440 of these sheets"，传统制作方式下1分钟（60秒）动画需要1440张塑料板，那么30秒对应的数量就是1440÷2=720张，选b。
4. 定位原文第二段"But this was still much faster than making the film by hand."，可知和传统手工绘制动画相比，CGI制作的速度更快，这是电影制作者选择CGI的原因，选a，文中没有提到CGI更便宜、更有艺术性的相关表述。
5. 定位原文最后一段"Toy Story showed that good CGI could bring films to life, and the film industry has never been the same since."，可知《玩具总动员》带来的巨大影响是它证明了优质CGI可以赋予电影生命力，彻底改变了电影行业，选c。
