>>14 Thank you for your reply. :-) Recently, I have tried to expand my impression making use of the site, gogakuru. The gogakuru is known as for learners of NHK learning programs. It is good for me to use it because it has many many English phrases. The phrases are on the basis of NHK's programs and good qualities. In particular, the phrases in bijinesu eigo nyu-mon, terebide ryuugaku, topu intabyu-ni manabu jibun wo kataru hyougenjutu are useful for speaking. For example, the expression, "let me" generates as following: Let me talk about the issue. Let me clarify my opinion on the issue. ttp://gogakuru.com/english/phrase/program/115_%E5%85%A5%E9%96%80%E3%83%93%E3%82%B8%E3%83%8D%E3%82%B9%E8%8B%B1%E8%AA%9E%E3%80%90%E5%89%8D%E6%9C%9F%E3%80%91.html
