18. Useful expressions That ’ s correct. It ’ s clear that … I doubt that … That ’ s true …. It ’ s hard to say … Well, maybe, but.. There is no doubt that … What ’ s your idea? Have you thought about …

19. Biology We can learn how to fight disease, How to protect the environment, How to grow plants for food. Essential to protecting the ecological balance and environment; people can’t live without living things and medicine.

20. Chemistry Is the key to the progress of human being; We can understand how the human body works and make medicines to cure disease. Chemistry also tell us what plants are made of and how we can make them grow faster and faster. Without it, we can ’ t know what caused pollution.

21. Physics Widely used in many fields, such as medicine, industry and agriculture. Without physics, we wouldn ’ t understand know how to build cars And we wouldn ’ t understand things like electricity. Physics is by far the most practical branch of science.

22. Maths You can ’ t learn physics or chemistry well without a good knowledge of maths. It is a tool in science and engineering.

23. Computer science It is now an indispensable tool in many fields. It can settle all kinds of problems at a high speed and can help people work easily.
