備考英語四級的時候，大部分的學生都是會用到四級考試試題的，掌握了考試試題，并多加練習，相信對四級考試的提升有幫助。今天我們為大家整理了英語四級考試的試題與答案，一起來看一下吧。

Design of all the new tools and implements is based on careful experiments with electronic instruments. First, a human “guinea pig” is tested using a regular tool. Measurements are taken of the amount of work done, and the buildup of heat in the body. Twisted joints and stretched muscles can not perform as well, it has been found, as joints and muscles in their normal positions. The same person is then tested again, using a tool designed according to the suggestions made by Dr. Tichauer. All these tests have shown the great improvement of the new designs over the old.

One of the electronic instruments used by Dr. Tichauer, the myograph (肌動記器), makes visible through electrical signals the work done by human muscle.

Another machine measures any dangerous features of tools, thus proving information upon which to base a new design. One conclusion of tests made with this machine is that a tripod stepladder is more stable and safer to use than one with four legs.

This work has attracted the attention of efficiency experts and time-and-motion-study engineer, but its value goes far beyond that. Dr. Tichauer’s first thought is for the health of the tool user. With the repeated use of the same tool all day long on production lines and in other jobs, even light manual work can put a heavy stress on one small area of the body. In time, such stress can cause a disabling disease. Furthermore, muscle fatigue is a serious safety hazard.

Efficiency is the by-product of comfort, Dr. Tichauer believes, and his new designs for traditional tools have proved his point.

21. What are involved in the design of a new tool according to the passage?

A) Electronic instruments and a regular tool.

B) A human “guinea pig” and a regular tool.

C) Electronic instruments and a human “guinea pig”.

D) Electronic instruments, a human “guinea pig” and a regular tool.

22. From the passage we know that joints and muscles perform best when __________________.

A) they are twisted and stretched

B) they are in their normal positions

C) they are tested with a human “guinea pig”

D) they are tested with electronic instruments

23. A “myograph” (Para. 2, Line 1) is an electronic instrument that ________________.

A) is able to design new tools

B) measures the amount of energy used

C) enable people to see the muscular movements

D) visualizes electrical signals

24. It can be inferred from the passage that ________________.

A) a stepladder used to have four legs.

B) it is dangerous to use tools

C) a tripod is safer in a tool design

D) workers are safer on production lines

25. Dr. Tichauer started his experiments initially to _________________.

A) improve efficiency

B) increase production

C) reduce work load

D) improve comfort

參考答案：

21. D) 由第一段的前兩句綜合所有的細節。

22. B) 見第一段的第四句。

23. C) 本題考察利用上下文理解生詞的能力。單詞myograph所在的第二段說，這種儀器make visible through electrical signals the work done by human muscle，與C)基本是同樣的’意思。

24. A) 由第三段的第一句中的“…a new design”可知，第二句中提到的a tripod ladder是a new design，相比之下，四條腿的梯子就是an old design了，也就是說，過去的stepladder是四條腿的。

25. D) 本題考察尋找細節。線索位于倒數第二段的第二句話。句子中的“Dr. Tichauer’s first thought”對應于題干中的initially，后面的句子都是說明為了舒適;本題的另一線索是最后一段的第一句，Efficiency is the by-product of comfort，由此可知，Dr. Tichauer最初關心的是comfort。

以上就是為大家整理的英語四級考試的試題與答案，希望能夠對大家有所幫助。考試的試題以及真題有很多，備考的過程中一定要仔細認真的閱讀，這樣才能夠得到真正的提升。
