4. Do you think that modern scientific inventions have really improved our lives?

现代科技已经渗透到我们生活的各个方面。这道题目问考生是否认为科技发明真正改善了我们的生活。答案是肯定的。需要斟酌的是从哪几个方面回答这个问题。其实，这道题目的回答采取举例说明的方式最具说服力。

Candidate 1: With the rapid development of modern technology, the scientific inventions have made a deeper effect on human beings' lives and do improve our lives.

Since you open your eyes and start a new day, you have already been interconnected with the scientific inventions. You use wash fountain to wash face so that you look more spirited. You turn on the bread-maker to cook the fresh bread or breakfast. You drive the car or take a bus to work, and on your way to school, you can turn on the radio and listen to the wouderful music. You sit in the chair, and listen to the teachers' explanations with the help of the computer. When you finish your work and come back, switch on the TV to watch and interesting movie, and at the same time you open the fridge, drink an ice-cold coke, which would be the coolest thing to relax yourself! After supper, you go to bed and read a book under the table lamp, which will accompany you till the midnight.

Just see how the scientific inventions have improved our lives in every common day. Try to imagine, can we live so comfortably and conveniently without them?

Candidate 2: Apparently, I do agree with the view that modern scientific inventions have really improved our lives.

21st century is the century of technology. Nowadays, technology exists everywhere and plays a vital role in our daily life. The development of technology has a significant effect on our society. Several technologies that we usually use include the computer, camera, and cell phone. These technologies make our life much easier and better.

For instance, the development of computer changes our life. Decades ago, people needed to do quantities of complex calculations by hand because they did not have computers, and more obviously, they did not have softwave for calculation. As a consequence, people spent hours on the equations which a computer can solve within a minute. With the development of computer, people are able to take advantage of it to compute many a complex function and mathematical calculation, which makes computer become one of the most useful inventions, as well as an assistant of human beings.

To sum up, I believe that modern scientific inventions have a profound impact on our life. It is very helpful and I suppose there will be more inventions in the future which can make our life more colorful.

Candidate 3: Our lives have been improved.

I do think modern scientific inventions have made a big difference to our lives. Food, drink, transportation and even culture, which just surround us, have been greatly changed.

For example, with Freeze Technology, food and drink can be transported from one place to another as far as you need. Retain Freshness Technology help to keep fish, meat or eggs fresh. Also, the new means of transportations, such as cars, subways, trains and airplanes has brought in new ideas to our lives. We will not be worried about the distance and go whereever we want.

Therefore, I do believe that modern scientific inventions have really improved our lives.

Candidate 1在开头就指出科技的确给我们的生活带来了巨大的变化，它改善了我们的生活。接着描述了我们从早上睁开眼开始，这一天的行动都与科技密切相关，语言流畅，列举的都是生活中的实例，却非常有说服力；Candidate 2也在一开头点明主题，然后重点列举了电脑给我们的生活带来了变化；Candidate 3的回答相对比较简单，开头回答了问题，在第三段列举了几个实例。
