This is the text (if you need help).
The UN will begin work to take action against North Korea. The UN believes North Korea tested a hydrogen bomb. It is the fourth time that North Korea tested a nuclear bomb. A hydrogen bomb is a lot more powerful than the atomic bombs dropped during World War II. The UN said the test is a "clear threat to international peace and security". The UN has not said what action it will take against North Korea, nor when they will take that action.
Not all countries agree on North Korea. The USA does not think the test was a hydrogen bomb. Both the USA and South Korea said the test was dangerous. Japan wants the UN to act quickly. It said the UN must act to keep its strong image. China had strong words. It said North Korea must keep its promises to stop nuclear testing. It also said North Korea must stop doing anything to make the situation worse.
Back to the North Korea lesson.
