Recently the unmanned aircraft which are called drones (無人駕駛飛機(jī)) have come into use for a number of business purposes.
Basically, a drone is a flying robot. The aircraft (飛行器) may be remotely controlled or can fly a through flight programs in their systems. The little planes used to be very costly. In the past, they were mostly used in the military (軍事). But as they have din price more people have begun to use them. Rescue workers and fanners are among the new users.

A company in France is using drones to help farmers examine their crops and limit the amount of fertilizer (肥料) they use. The fast development of computer technology, image sensing devices (圖像感應(yīng)設(shè)備), satellite navigation (衛(wèi)星導(dǎo)航) and cell phones has led to lower-priced drones. Researchers and developers have learned how to build smaller and less-costly drones.
Moviemakers are using drones to film from the sky. Historians (歷史學(xué)家) use them when they explore a. buildings. Rescue workers use them to look for people. And now farmers are using them to m their crops.
Romain Faroux is a French businessman who starts companies. His father was a farmer. He believed drones could help fanners. He helped create a company that developed a small drone that could be controlled by people on the g. They called it “Agridrone (農(nóng)業(yè)無人機(jī)).” It uses a special “optical sensor (光學(xué)感應(yīng)器)” to examine crops.
The technology used is similar to that used by smartphones except it has wings. A computer program directs the drone to fly over the crops. The sensor on the drone records four different-colored “bands” of sunlight (太陽光帶) that are reflected off (反射) the crops.
Jean-Baptiste Bruggeman is a farmer. He says the drone flies over his crops at different time of the season. He says this provides a lot of information about his crops. The drone pictures show him the exact amount of fertilizer the crops need. It also shows exactly where the fertilizer is needed.
Romain Faroux says farmers use information g by the Agridrone to place fertilizer only in areas where it was needed. This saves money and reduces pollution. Before they used the drones, farmers would put the same amount of fertilizer everywhere. Drones also save time because farmers can examine u to three hectares (公頃) in about a minute.

【答案】automatically;dropped;ancient;monitor;ground;gathered/got;up
【解析】這篇短文主要講了關(guān)于無人飛機(jī)的情況。

(1)上下文暗示題。首先可判斷詞性為副詞。另上下文提到由于無人駕駛飛機(jī)通過輸入的程序即可飛行,故無人飛機(jī)可以自動(dòng)地飛行。根據(jù)語境及開頭首字母此空應(yīng)填automatically。

(2)上下文邏輯題。首先可判斷此處是一個(gè)現(xiàn)在完成時(shí),故應(yīng)填一個(gè)動(dòng)詞的過去分詞。另由于上文說到之前無人駕駛飛機(jī)花費(fèi)高昂,故在轉(zhuǎn)折詞后應(yīng)填一個(gè)表示價(jià)格下跌的動(dòng)詞。根據(jù)首字母此題應(yīng)填dropped。

(3)歷史學(xué)家使用無人駕駛飛機(jī)一般是需要探索古代的.古老的建筑。根據(jù)分析及所給首字母此題應(yīng)填ancient。

(4)根據(jù)語境農(nóng)民可以用無人機(jī)監(jiān)控他們的莊稼。所以此題應(yīng)填monitor。

(5)固定搭配題。on the ground在地上。此處指的是人們可以在地面上操控?zé)o人駕駛飛機(jī)。所以填ground。

(6)信息是被“搜集”或“得到”的,故根據(jù)首字母能想到gather,又因?yàn)榇颂幨潜粍?dòng)語態(tài),需變形為過去分詞。所以填gathered/got。

(7)根據(jù)語境及固定搭配up to(多達(dá))可知此題應(yīng)填up。

【題目】閱讀下列短文,從每小題所給的A、B、C、D四個(gè)選項(xiàng)中選出一個(gè)最佳選項(xiàng)。

To us, it seems so natural to put up an umbrella to keep the water off when it rains. But in fact the umbrella was not invented as protection against the rain. Its first use was as a shade (遮蔽) against the sun.
Nobody knows who first invented it, but the umbrella was used in very ancient times. Probably the first to use it were the Chinese, back in the 11th century BC.
We know that the umbrella was used in ancient Egypt and Babylon as a sunshade. And there was a strange thing connected with its use: it became a symbol of honor and power. In the Far East in ancient times, the umbrella was allowed to be used only by those in high office or by royal people such as the kings or queens.
In Europe, the Greeks were the first to use the umbrella as a sunshade. The umbrella was in common use in ancient Greece, but it is believed that the first people in Europe to use the umbrella as protection against the rain were the ancient Romans. During the middle ages in Europe, the use of the umbrella almost disappeared. Then it appeared again in Italy in the late sixteenth century. And again it became a symbol of power. Umbrellas have not changed much in style during all this time, though they have become much lighter in weight. It wasn't until the twentieth century that the umbrellas for women began to be made in all kinds of colors.

【題目】閱讀理解

You probably know many of the things that you can do with the hundreds of different muscles in your body. But have you ever thought about how the muscles in an animal's body are different from yours? An animal's muscles are made to do the things that are most important for its life.
Lions are hunters. They depend on their ability to catch other animals. Lions must be fast in order to catch their prey(獵物). The powerful muscles in their back legs allow them to run at speeds of more than 30 miles per hour. They can also jump a distance of more than 35 feet. The strong muscles in their front legs help them catch their prey.
Snakes also use their muscles for hunting prey and for movement, but their muscles work in very different ways than lions' do. Because snakes do not have any legs, they use their muscles to push against the ground or other objects to move themselves forward. Their muscles also allow them to eat things that seem much too large. For example, a snake may eat an egg that is larger than the width of its body. How does this happen? The snake's strong neck muscles work together to push the egg down the mouth.
The elephant's long nose has a lot of muscles. Scientists believe that the nose alone has more than 100,000 muscles! This is because the elephant uses its nose much in the same way that people use their hands and fingers. Even though the nose is large, it can perform surprisingly tasks. For example, an elephant can pick up a small leaf from the ground. The nose can also be a powerful tool. An elephant can use its nose to pick up a tree by its roots or even to lift a baby elephant.
The great muscles of these animals seem pretty unbelievable. But the muscles in your body work exactly the way you need them to. After all, it might be fun to be able to jump a distance of 30 feet, but as a human being, there is just not much need for it.
(1)The underlined word “hunters” in Paragraph 2 means persons or animals that.
A.keep animals for fun
B.raise animals for meat
C.catch animals for food
D.run after animals for exercise
(2)All the following are talked about in the passage EXCEPT.
A.An elephant's nose is strong enough to pick up a tree by its roots.
B.The strong muscles in the back legs help lions catch their prey.
C.Snakes can't move themselves forward without their muscles.
D.Muscles in an animal's body are different from a human's.
(3)According to the passage, what makes the muscles in your body different from an animal's?
A.The exercise.
B.Your parents.
C.The environment.
D.Your needs.
(4)Which of the following shows the structure (結(jié)構(gòu)) of the passage? (P = Paragraph)
A.
B.
C.
D.
