Hello

    I just joined "English Kids". Feeling bad that I could have found this earlier. Now my son is 4 years old.

    He can understand but not started speaking English. What should I do?

Hi

    Thanks for your post. It's never too late to start practicing English with your son! It's great that he ready understands some English, and in his own time he will start to speak. This is certainly a go time to start practicing English with him and I hope that the advice in the article will help.

    Don't expect too much too quickly. Children often need a lot of time to take in the language before they begin speaking themselves. The main thing is to be patient, give your son lots of encouragement and to show him that you enjoy speaking English, If you are enthusiastic, he will be too!

    I hope that help.

Best wishes.

已知函数f（x）=$\sqrt{3}$sin（ωx+φ）（ω＞0，﹣$\frac{\mathrm{\pi }}{2}$≤φ＜$\frac{\mathrm{\pi }}{2}$）的图象关于直线x=$\frac{\mathrm{\pi }}{3}$对称，且图象上相邻两个最高点的距离为π．

求ω和φ的值.
