阅读下列短文,从短文后各题所给的A、B、C、D四个选项中,选出最佳选项。

Every living thing on Earth is either a plant or an animal, right? Wrong! Many organisms(有机体)in our world are neither. Some of them float through the air, and some lie hidden in the ground. They do not need sunlight to survive, and if the weather becomes too cold, they can become inactive until conditions improve.

What are these? They are called fungi(菌类), and you see them almost every day. Many kinds of fungi seem disgusting, such as the green black things that appear on the food which are left too long in the refrigerator. But other kinds are not so bad. For example, the yeast that is used to make bread and mushrooms (蘑菇) are both fungi.

What makes fungi different from plants and animals? An animal can move around by itself. Fungi get around too, but they don't have feet, wings, or tails. They have to wait for wind or some other outside force to move them. Plants are different from fungi because they have chlorophyll(叶绿素). It helps them make food from the energy in sunlight. Fungi do not have chlorophyll.

Some fungi are bad, while others are not. Some fungi cause diseases, such as athlete’s foot, which makes feet uncomfortable. Other kinds of fungi can be used to make medicines, which have saved many lives.

Fungi clean up more than wounds, though. They are the world’s first recyclers. Without fungi, our world would be a mess. Since fungi cannot make their own food as plants do, they must get their food elsewhere. Many fungi get their food from dead plants. They break them down and turn them into soil. The fungi get a meal, and the world gets a housecleaning.

Each summer,you hear news that some sports players are sent to hospitals because it is too hot. Our bodies can't be outside in the sun for a long time. So in hot summers,be careful about playing sports outside.

Firstly,to play sports safely in hot weather,you must drink water. Sports drinks are great for athletes,but they have so much sugar that they'll dehydrate(使脱水)you more. However,drinking a few bottles of sports drinks will be good for you.

Secondly,be sure to take enough breaks to let your body rest. If your coach doesn't let you take enough breaks in the heat,don't wait until you feel uncomfortable. Just be honest with your coach when you need breaks.

Thirdly,when you have a break,don't sit in the sun. With the sun beating down on you,you'll only heat up and sweat(冒汗)more. Take a seat under a tree,or even better,go indoors for a little while. Cooling yourself down can help you stay active longer.

Fourthly,remember that the earlier in the day you start your exercise,the cooler it will be. If you can start practice before the sun comes up,you have a few good hours to practise in the cool hours of the morning. Also,the earlier you practise,the earlier you can finish the exercise. If you need more practice time,come back to the field later in the evening,when the sun is setting.

Last but not least,you should watch what you eat. Eat food which is high in water,starch(淀粉)and carbonhydrate(糖类),but be sure to get a good balance in your diet.

As long as you pay attention to the above,playing sports safely in the heat isn't a difficult thing.

B.You need to tell your coach when you feel tired.

C.Sitting under a tree is better than staying indoors.

D.Eating lots of sugar is necessary for sports safely.
