    There are many dangerous sea creatures in the world. The following are some examples.

    The needlefish are commonly seen living near the surface of tropical (热带的) waters. But they can also break cover the water，and once in the air they can become dangerous flying swords. Though it is rare，people have been seriously hurt and even killed by the fish．Night fishermen in small boats are at particular risk because their lights may attract the fish.

    Saltwater crocodiles are the world's largest crocodiles，sometimes reaching 23 feet in length and topping 2，200 pounds. Yet these crocodiles hunt quietly，lying in wait below shoreline waters to attack turtles and thirsty animals that have come to drink. Saltwater crocodiles kill a number of people each year.

    There is no doubt that the great white shark sits atop the ocean food chain. The world's largest fish can weigh at over 5，000 pounds and reach lengths of more than 20 feet. Great white sharks have about 3，000 teeth，which they typically sink into sea lions，seals，and sea turtles. These sharks are responsible for a third to a half of the 100 shark attacks on humans every year.

    The sea anemone (海葵) may look like the beautiful flower for which it's named，but fish that swim too close may regret it. The sea anemone，which lives on the sea floor，uses its poisonous tentacles (触须) to stab passing creatures with a kind of poison—making them helpless and fit to be eaten.

    The surgeonfish (刺尾鱼) is an attractive reef fish that is poisonous. Scientists believe that the world's seas hold some 1, 200 different surgeonfish species and think that they injure about

    50，000 people per year. But the surgeonfish poison can also bring great benefit—they are useful in the development of new drugs.

    Do you ever feel like you are studying a mad rush of one subject after another? When things happen at such a 1pace, it is easy to lose sight of what you are learning. It is important to 2 every now and then to think about what you've been learning.

    Self-reflection means stopping the mad rush and3 yourself so your brain can evaluate what it has already4. Some people prefer to do their self reflections5, while others keep a journal. Either method can work, depending on what your own personal 6 is.

    School textbooks are often divided into units. This can make it7 for someone to begin the process of self-reflection. Watch for the times when you complete a unit of study. Sometimes you are reminded that the unit is 8 because there is some kind of test or quiz. Use these natural 9 as opportunities to stop and reflect.

    You should find a 10 place—anywhere without noise is OK. This can even be sitting at your desk at school when you finish something 11and the other students are still working. If you are going to take notes, take out your journal. Write down some notes on things that you 12 learned in this unit. Let your mind think about the notes you have written and make some 13.

    Sometimes just pausing to think deeply allows your brain to make connections14new information can quickly appear when you 15 it again. Next, think about things that you still wonder about. 16 maybe you learned about a certain body system, but you don't 17 how it works with the other body systems. Maybe you learned a new way to solve a math problem, but you're not sure when to use it. Writing down your18 will help you remember to continue seeking answers the next time you19 the same topic.

    Self reflection is an essential skill for a 20 student. If you have never taken the time to reflect, try it now.
