1. You are well familiar with both the construction and the pronouns.

They asked us to help them.

The science adviser told me to repeat the experiment.

If you are not sure of the pronouns remember these sentences.

2. The Infinitive should be used in the Complex Object construction:

1. with to (to V)

after such verbs as:

want, ask, beg, expect, help, enable, allow, think, believe, etc.

2. without to (V)

after such verbs as:

let, make

see, watch, hear, feel, etc.

General

1. Find seven cases of the Complex Object in the passage below.

Technologies such as distributed computing, voice and visual recognition, and wireless broadband connectivity will open the door to a new generation of autonomous devices that enable computers to perform tasks in the physical world on our behalf. One reason for this gap is that it has been much harder than expected to enable computers and robots to sense their surrounding environment and to react quickly and accurately. The access to cheap computing power has permitted scientists to work on many of the hard problems that are fundamental to making robots practical.

Another barrier to the development of robots has been the high cost of hardware, such as sensors that enable a robot to determine the distance to an object as well as motors and servos that allow the robot to manipulate an object with both strength and delicacy. The resulting enhancement of capabilities, combined with expanded processing power and storage, allows today’s robots to do things such as vacuum a room or help to defuse a roadside bomb we provided the common foundation that enabled programs developed for one set of hardware to run on another.

2. Translate into English.

1. Полученные результаты позволили исследователям прийти к другому (different) выводу.

2. Этот прибор дал ученым возможность исследовать новое явление.

3. Новые данные позволяют нам приблизиться к пониманию этого процесса.

4. Время не позволяет (does not allow) нам рассмотреть все особенности данного процесса.

Make vs. cause, force

1. Translate the sentences.

1. I have harnessed the computer and made it do actual, practical work.

2. There are no business models yet for how utilities can make that happen, even though several companies are already experimenting with new ways to make money.

3. If this energy is positive, it causes spacetime to expand at an exponentially accelerating rate.

4. This often causes designers to spend time figuring out why rules are not firing concurrently.

5. The glaciers, particularly in the Himalayas, may disappear and cause some of the major rivers to become much more variable.

6. Himalayas, may disappear and cause some of the major rivers to become much more variable.

7. The key was finding a thickness-substrate combination that caused the film to form with the right mixture of tetragonal- and rhombohedral-shaped crystals.

8. That makes it seem as though men and women have moved closer in body shape.

9. There are no business models yet for how utilities can make that happen.

10. The company is forcing me as a designer to think of this as a relationship between the player and a piece of technology.

Note:

Being formal, the verb cause is often used in scientific literature

In colloquial speech the verb make is more common.
