A 试题分析:没有新闻就是最好的新闻。News是抽象名词,不可数,故谓语动词用单数,选A。 考点:主谓一致 点评:be动词往往根据句子的主语而有所不同,其应用原则可以结合如下歌谣来记忆;我用am,你用are;is用在他、她、它。单数名词用is,复数名词全用are。注意当主语是不可数名词时,谓语动词用单数。
To find out whether bees can see colours, the following experiment is made. A table is put in a garden, and on the table is a blue card with some sugar on it. As soon as one bee finds the sugar, many more come to it one after another in a short time. It seems that one bee is able to tell the news of food to the other bees in their “ home”. After a moment, the blue card with sugar on it is taken away. Instead of this card, another blue card is now put on the left side of the first feeding place and a red card to its right. Nothing can be seen on the two cards. Very soon bees arrive again, and fly towards the blue card. No bees go to the red card.
