- New farming methods Topic: In recent years, farming practice has changed to include methods such as genetic modification and the use of technology to improve crops. Some people believe these developments are necessary, while others regard them as dangerous and advocate a return to traditional farming methods. Discuss both points of view and give your own opinion. Relatively new part of biotechnology is genetic engineering. It is set of methods to insert some genes from one to another organism for obtain improved crops. I think this is really profitable technology but it requires careful use. Unfortunately, genetic manipulations can lead to making dangerous produce. Genetic engineering is young sphere. Opening of the structure of DNA was done about a half century ago. Since then genetic technology is developed by scientists but it is too little to be certain in experement outcomes. Therefore, GM food, mayby dangerous without accurate during creation. GM organisms often include genes of poison guard against pests, so it is necessary to safety control new crops for people. Inspit of dangerous benefits of new method is clealy. It is increase crop yeilds because some genetic manipulation decrease life cycle therefore people gain more crops from the same field for a season. GM crops unexpensive because thay as a rule include resistance to insects, virus and fingal pests so spraying by chemicals unnecessery. In my opinion using new technology can lead to escape from food problem. As mantiond above new methods in agriculture is controversial but they have the prospect of high profit. Youth of experimental base and innovation technique require screening by scientists.
May 31, 201540 - Apes' language (part 2) Gorilla Coco was educated by F.Patterson american scientist. Coco exspressed not only simple necessities but also complex sensations and emotions, using 375 sign-words. She understood abstract concepts such as "boredom", "imagination", past and futur. Ape Lana studied nearly 60 leksigramm. Lana could make phases with requesting to start the movie or play music. Some apes sing together to enjoy.

Я обещала себе вернуться «к воде». По крайней мере два раза в неделю буду ходить в бассейн.
Сегодня начинаю...
Я сижу в метро и считаю, сколько минут смогу плавать, чтобы успеть добраться на работу без стресса. 50 минут! Я очень довольна. И сразу думаю о том, как надену очки для плавания и буду плавать брассом и обратно на спине. Я надеюсь, что так рано утром в спортивном центре никого не будет, и весь бассейн будет только для меня.
P.S.: Действительно, в бассейне плавал только мой коллега по работе и я. Мы не разговаривали, а плавали потихоньку. Но по дороге на работу мы уже смеялись и поделились друг с другом, сколько воды из бассейна мы выпили.Очень хорошо!

But an ape teached to speak human language can not speak, because it's the voice system differ from human system, including the control voice center into the brain. Though apes with teaching can communicate in sign language, like chimpanzee Washoe. Washoe was educated Allen and Beatris Gardner. They are american zoopsychologists. After a few month Washoe had used a few tens sign-words and then near 300 words. She creatively used her vocabular. For example, if she needed to open the fridge, she showed 'the open coldbox - eat - drink'. Washoe made up phrases such as "give me tikle". If she saw an unpleasant somebody, she show "dirty". Washoe preferred to call duck "water-bird" instead of the special sign. The first Washoe's cub was died soon after birth. She sat beside her cub and showed "baby", "baby", waiting the answer.
