题目内容
There __________ some children in the painting room. They are studying painting.
A.is B.are C.am D.was
B
【解析】
试题分析: There be结构在英语中表示“某处(时)有某物(人)”。句型构成:引导词There+连系动词be+主语(人/物)+地点(介词短语或副词)。 There be结构的主谓一致:适用于就近一致——当主语是可数名词单数或不可数名词时,其谓语必须用单数;当主语是可数名词复数时,其谓语必须用复数。因some children是复数形式故be要选择are,故选B。
考点:there be结构的基本构成。
点评:there be结构的现在时态还有一个非常重要的考点,就是当be的后面出现若干个名词,有单数也有复数,有可数名词也有不可数名词,此时be的形式就要遵循就近原则,谁离他最近谁决定be的形式,这是中考中考查的重点内容,还有there be结构的将来时的基本构成也是重点。
There ________some juice and some cakes on the table.
A.is | B.are | C.am | D.be |
Germs(细菌) are everywhere. You can’t see them, but they are on your desk, on your computer, and even in the air!
Like people, germs move around the world. They fly with us on planes. When food, clothes, and other things travel around the world, germs travel, too. Some germs are safe, but some are dangerous. Germs cause illnesses like colds and the flu.
Warmer Weather Brings Germs
The world’s weather is changing. Cooler countries are getting warmer, so insects from hot countries can move there. Some of these insects, like mosquitoes, carry dangerous germs. These germs cause headaches, fever, and can even kill people.
Under Your Skin
Your skin protects you from germs. It stops some germs, but not all. They can enter your body when you eat, or when you have a cut. Germs are on your hands, too. They enter your body when you touch your eyes, nose, or mouth.
Fighting Germs
Your immune system(免疫系统) protects you, too. When germs get inside your body, your immune system finds and kills them. Special cells(细胞) move around your body and fight germs. They help you stay healthy. Other cells make antibodies. Antibodies help your body find and stop germs.
What can you do to fight germs? You should wash your hands with soap and water. Soap kills many germs, and water washes them away.
