【題目】句型轉換。請根據(jù)括號內的要求改寫下列句子。

【1】This is an eraser.（改為否定句）_______an eraser.

【2】This is my friend.（改為復數(shù)句子）________my _________.

【3】She is my friend.（變一般疑問句）__________she _______friend？

【4】This is my brother.（就畫線部分提問）________________？

【5】Are these your friends？（作否定回答）_________ ，___________ .

【答案】

【1】 This isn’t

【2】 These are friends

【3】 Is your

【4】 Who is this？

【5】 No they aren’t

【解析】

【1】句意：這是一塊橡皮。原句中有be動詞is，變否定句需要在be動詞is后加not，is not=isn’t，故填This isn’t。

【2】句意：這是我的朋友。改復數(shù)句時原句能變復數(shù)的都要變化，this是“這個”，變成復數(shù)“這些”these，對應的be動詞也使用復數(shù)形式are，名詞friend變成復數(shù)形式friends，故填These are和friends。

【3】句意：她是我的朋友。原句中有be動詞is，所以在變一般疑問句的時候be動詞is提前即可，原句中的“my”是“我的”，一般疑問句變成your（你的），故填Is和your。

【4】句意：這是我的哥哥。劃線部分是“我的哥哥”，所以提問就是在問身份，用who，后加一般疑問句并刪掉劃線部分即可，故填Who is this？

【5】句意：這些是你的朋友嗎？原句是一般疑問句，be動詞開頭，所以回答的時候仍要使用be動詞，否定回答要用no，原句中的指示代詞these意為“這些”，在回答的時候要用they來代指，故填No, they aren’t。

【題目】任務型閱讀
閱讀下列短文，根據(jù)短文中的信息完成文后表格。在答題卡標有題號的橫線上，寫出空缺處所填單詞的正確形式。（每空一詞）
To make our digestive (消化的) system work well, we should avoid doing some things after having a meal, for example, drinking water. It is true that a person should drink 8 glasses of water every day to stay healthy. However, drinking water right after eating or even during a meal may disrupt (擾亂) digestion. It might influence the natural levels of acid and bile (酸和膽汁) that are necessary for proper digestion. What's more, drinking cold water after eating might slow down （減慢）digestion. So try to avoid drinking water at least an hour after a meal, and avoid drinking it while eating.
Though walking after eating is healthy, doing it at once after a meal is not. Doing so will make it difficult for the digestive system to take in nutrients (營養(yǎng)) from the food. Besides, the blood will flow towards other parts of the body, like legs, hands, etc. That will make the digestive tract(消化道) not have enough blood flow for proper digestion. So we should wait for at least 2 hours after eating, and then begin exercising.
Sleeping should also be avoided right after eating. This is because going to bed right after a meal will lead to improper digestion. What's more, such a habit will also make you put on a lot of weight. Therefore, wait for an hour or two, and then go to sleep.
Many of us have the habit of drinking tea just after lunch or dinner, which is really unhealthy. The tea leaves are rich in acid which prevents the protein（蛋白質）in the food from digesting. The best time to drink tea is at least one hour after eating.
Eating fruits right after a meal may fill the stomach with air and we'll feel uncomfortable. They will also take time to reach the digestive tract, disturbing the whole process of digestion. To protect your stomach from digestive problems, eat fruits before or after 1-2 hours of a meal.
In a word, if you avoid doing all the above things after eating, you will surely make your digestion easy, and you will be less likely to have digestive problems.
