, we must be able to read the language, and fourthly, we must be able to write it. We must be able to make sentences that are grammatically correct.
There is no easy way to success language learning.
good memory is a great help, but it is not enough only
(memorize)rules from a grammar book. It is not much use learning by heart long lists of words and their
(mean), studying the dictionary and so on. We must learn by using the language.
we are satisfied with only a few rules we have memorized, we are not really learning the language. Learn through use is a good piece of

The discovery (make) by a team
(consist) of scientists from the Massachusetts Institute of Technology (MIT) and high school students
were seeking a natural water filter—one that would help communities in developing countries that do not have
(accessible) to modern water filter systems.
The(research), led by Professor Rohit Karnik, decided to turn to trees for help because they could allow liquid to flow through, while blocking out air bubbles.
They began by cutting 1.5-inch-wide sections of tree bark from the branches of a white pine tree. The people related then tested the wood’s filtering ability by pouring water containing red dye particles of different sizes through.their amazement, they found that it was effective in trapping all the articles.
(encourage), the team conducted
experiment, this time with water that contained bacteria. Sure enough, the sapwood held back 99% of the bacteria, allowing only 1% to flow through.
