Part 1. The Earth/ Part 2. The Life on Earth/ Part 3. In Space

Study the information in the table below:

Future Perfect Active – служит для выражения будущего действия, которое закончится к определённому моменту или к началу другого действия в будущем. Time Markers – by … (by next year, by 5pm tomorrow, by next day, …) already, before, when
Positive	Negative	Interrogative
□ shall/will have Ved/V3 ■. People will have measured the size of the neighbouring galaxy by the next century. □ – People will have Ved – will have measured ■ – the size of the neighbouring galaxy T.M. – by the next century	□ shan’t/won’t have Ved/V3 ■. The scientists won’t have finished experiment by the end of the week. □ – The scientists □ won’t have Ved – won’t have finished ■ – experiment T.M. – by the end of the week	1. Optional: Shall/Will □ have Ved/V3 ■? Will the scientists have discovered new phenomena on the moon surface? – Yes, we had./ No, we hadn’t. 2. Special: Q.w. shall/will □ have Ved/V3 ■? When will the observer have found the necessary point of his research? – When the experiment is over.

Exercise 1. Read the situations and write sentences with the verbs in brackets in future perfect:

1. I worked very hard today. I’m very tired now. I need a good rest. When the sun (rise) will have risen tomorrow I am still sleeping.

2. The rain … (stop) by that time.

3. This plant … (blossom) by the end of June.

4. While you are trying to catch a butterfly it … (fly) away.

5. The moon has just started its new turn around the earth. It … (complete) the orbit around the earth in 27 1/3 days.

6. If we do not care about the earth today it … (disintegrate) one day.

Study the information in the table below:

Future Simple	Future Continuous	Future Perfect
□ shall/will V1 ■. Pluto will start its new turn around the sun tomorrow.	□ shall/will be Ving ■. Pluto will be moving around the sun about 2473/4 earth years.	□ shall/will have Ved/V3 ■. Pluto will have completed its orbit by that time.

Exercise 2. Read the following text and decide true or false are the statements below:

Scientists are working at the new project. They have already finished the old one by spring. They were studying the movement of planets in the solar system. Last century they found that: there are 9 planets and 61 satellites altogether in the solar system; Mercury, with a diameter of 3,112 miles, is the planet nearest to the sun; Pluto, the most distant planet, takes about 247 3/4 earth years to orbit around the sun; when comets approach the sun, their tails begin to glow from friction with the solar wind; and the sun, an average-sized star, makes up about 99 percent of the mass of the solar system. In their new project they are going to send 50 artificial satellites to look for some new information about space. Next three years they are going to build 20 new satellites. It will take three more years to taste them. On the 7^th year the scientists will have sent these machines into space. The scientists will be working out other 30 machines during next 10 years. It will take three more years to taste the rest of the 30 satellites. Only when all 50 satellites will be working in space the project is over.

Statements:

1. The scientists will have discovered the 61^st satellite by next spring. – false

2. It will take Pluto about 247 3/4 earth years to orbit around the sun.

3. The scientists will have discovered some new phenomena in space with a help of the modern equipment.

4. First 20 satellites will be working in space for ten years when the scientists have worked out other 30 machines.

5. It will take 30 years to start the first twenty satellites.

6. It will take 13 years to send other 30 machines into space.

7. The scientists will be working at the project during 30 years.

8. According to the project 50 satellites will be working in space in 23 years.
