科學(xué)的進(jìn)步讓曾經(jīng)被認(rèn)為不可能的事情變成了現(xiàn)實(shí)，以色列科學(xué)家訓(xùn)練的金魚(yú)竟能控制車輛的運(yùn)動(dòng)方向！

1 Israeli researchers said they had successfully taught a goldfish to drive a small robotic car. The team said the fish showed its ability to navigate toward a target in order to receive a food reward.

2 For the experiment， the researchers built what they called a Fish Operated Vehicle （FOV）. The main part of the vehicle was a fish tank attached to a moving machine with four motorized wheels. Attached to the top was a system used to follow all movements of the fish and vehicle. The system was operated by lidar （激光雷達(dá)）.

3 When the system observed that the fish was up against the side of the glass while facing forward， it would move the vehicle forward in that direction. The researchers said that over time， the fish learned that putting itself in these positions would move the FOV in those directions. In this way， the fish was able to drive the vehicle.

4 Researcher Shachar Givon said it was surprising how quickly the fish learned to drive the vehicle. “They re confused at first—they don t know what s going on，” he said. “But they re very quick to realize that there is a correlation between their movement and the movement of the machine that they re in.”

5 The team used six different goldfish in the study. They said the fish were able to navigate to the target even if something happened to temporarily take them off the path. And， they said， the fish were not fooled by false targets placed by the team.

6 Researcher Ronen Segev said some of the fish proved to be“excellent” drivers. Others， he said， showed that while they could control the vehicle， they were not very good at driving it.

7 He also said， “We humans think of ourselves as very special. And many think of fish as primitive， but this is not correct.” He added that there are many other“very important and very smart creatures”.

Ⅰ. Analyze the difficult sentence in the text

When the system observed that the fish was up against the side of the glass while facing forward， it would move the vehicle forward in that direction. 當(dāng)系統(tǒng)觀察到魚(yú)面朝前，靠在玻璃的一側(cè)時(shí)，它會(huì)將車輛朝那個(gè)方向向前移動(dòng)。

【點(diǎn)石成金】本句是一個(gè)主從復(fù)合句。句中，When引導(dǎo)時(shí)間狀語(yǔ)從句;that the fish was up against the side of the glass是賓語(yǔ)從句，作動(dòng)詞observed的賓語(yǔ);while facing

forward是省略了主語(yǔ)與系動(dòng)詞的時(shí)間狀語(yǔ)從句。
