Hi, everyone! My name is Lin Tao. I'm in Changsha, Hunan.
Now I 1. (eat) lunch in a very special restaurant with my friend. Do you want 2. (know) how special it is? The restaurant is in the 3. (centre) place. In this restaurant, there are only two 4. (wait). But every day, there are over 800 people waiting for their 5. (order). That's because this restaurant 6. (have) three robot cooks. The robots can cook very 7. (quick). And people can get food in only five 8. (minute). Then they can enjoy their food 9. (slow) there.
Li Zhiming is the inventor(发明者) of the robot cooks. He says, "In my city, such a big restaurant needs eight to ten cooks and waiters. But my restaurant is different."
I'm looking forward to 10. (enjoy) food made by robot cooks. How about you?

1. am eating
2. to know
3. central
4. waiters
5. orders
6. has
7. quickly
8. minutes
9. slowly
10. enjoying

1. 句中时间标志词Now表示动作正在发生，要用现在进行时，结构为am/is/are+现在分词，主语是I，be动词用am，eat的现在分词是eating，故填am eating。
2. 固定搭配want to do sth. 意为“想要做某事”，此处填动词不定式to know。
3. 空后是名词place，需要用形容词修饰名词，名词centre的形容词形式是central，意为“中心的”，故填central。
4. 空前有数词two，后面要接可数名词复数，动词wait对应的表示“服务员”的名词是waiter，复数形式为waiters。
5. 形容词性物主代词their后接名词，此处表示“他们的订单”，不止一份订单，order要用复数形式orders。
6. 主语this restaurant是第三人称单数，句子为一般现在时，谓语动词have要变为第三人称单数形式has。
7. 空格处修饰动词cook，要用副词，形容词quick的副词形式是quickly。
8. 空前有数词five，后面接可数名词复数，minute的复数形式是minutes。
9. 空格处修饰动词enjoy，要用副词，形容词slow的副词形式是slowly。
10. 固定搭配look forward to doing sth. 意为“期待做某事”，此处to是介词，后面接动名词，enjoy的动名词形式是enjoying。

二、阅读理解。
If you fly across several time zones, you may have jet lag(时差反应). You arrive in a new time zone, but your body is still living on the time in the old time zone. You may be ready for dinner at midnight, and you may want to sleep all day.
People have jet lag because all living things have a biological clock(生物钟). For example, plants begin to work at sunrise. When winter comes, birds fly to warm places. Some insects like bees also seem to set their alarm clocks to look for food.
Some scientists did an experiment(实验) with bees in Paris. They put out sugar water at 4:00 p. m. every day, and the bees came to drink the water at exactly the right time. Then the scientists put bees in a dark room. The bees still came out at the same time. Later the scientists took the bees to New York. The bees came for the food at the right time again, when it was only 10:00 a. m. in New York. Their bodies were still on Paris time.
Humans have a biological clock, too. It tells us when to sleep and eat. Our bodies are controlled by a biological clock, but we can learn to adjust(调整) it to different time.
()1. How many examples of the biological clock does the writer show in Paragraph 2?
A. Two. B. Three. C. Four.
()2. When did bees come out for food in New York?
A. At 10:00 a. m. (Paris time).
B. At 4:00 p. m. (Paris time).
C. At 4:00 a. m. (New York time).
()3. What is the purpose(目的) of showing the experiment with bees?
A. To explain how bees set their alarm clocks.
B. To tell us that bees look for sugar water to live.
C. To prove(证实) that living things have a biological clock.
()4. What can we learn from the passage?
A. Humans can adjust their biological clock.
B. The biological clock isn't useful at all.
C. Bees couldn't tell the time in the dark room.

1.B 2.B 3.C 4.A

1. 第1题：定位文章第2段，文中一共列举了3个生物钟的例子：植物日出时开始活动、冬天候鸟飞往温暖的地方、蜜蜂设定闹钟觅食，因此答案选B。
2. 第2题：定位文章第3段，科学家在巴黎时每天下午4点放置糖水，蜜蜂习惯了这个时间，被带到纽约后它们的身体仍然遵循巴黎时间，在巴黎时间下午4点出来觅食，此时纽约当地时间是上午10点，因此答案选B。
3. 第3题：文章第2段先提出“所有生物都有生物钟”的观点，后续展示蜜蜂的实验，就是为了证实生物确实存在生物钟，因此答案选C。
4. 第4题：根据文章最后一段“Our bodies are controlled by a biological clock, but we can learn to adjust(调整) it to different time.”可知人类可以调整自己的生物钟；B选项表述错误，生物钟可以提醒我们作息进食，十分有用；C选项表述错误，蜜蜂在暗房里依然能准点出来觅食，说明它们可以判断时间。因此答案选A。
