問題詳情：

 Every year, over 7.72 trillion kilograms of plastic is washed into the oceans. There are five huge areas in the world’s oceans that are a “soup” of floating rubbish. One of these areas, the Great Pacific Garbage Patch (GPGP), is three times as large as France.

Over a year ago, a group called Ocean Cleanup began using a huge floating screen to try to clean up plastic pollution in the ocean. After several failures, the group is now collecting plastic in the Great Pacific Garbage Patch. But the plastic is spreading out over a large area, so it's impossible to collect it piece by piece. So, the Ocean Cleanup had a plan. They got a long floating U-shaped tube with a screen hanging below it. As the tube and screen are pushed by the water and the winds, the U is meant to collect plastic rubbish, making it easy for a ship to collect and remove the plastic. The system uses the power of the wind and ocean, so it doesn’t need fuel.

The group began testing the first version, called “System 001”, last September. But it soon became clear that the screen was just moving with the plastic, not collecting it. Sometimes plastic would wash over the top of the tube. Even worse, System 001 got broken by surging seas and had to be towed to Hawaii for repairs.

But Mr. Slat, who got the idea for the Ocean Cleanup system, sees the project as an experiment, which means a failure is a chance to learn. The team collected and studied lots of information about what worked well and what didn’t. Then they changed the design. In June, an improved version, called “System001/B” was towed back to the GPGP.

The new version has a parachute (降落傘) attached to it. This makes the system move slightly slower than the plastic, allowing the plastic to be collected inside, as planned. But this success is still just the beginning of the work of the Ocean Cleanup. They want a better and larger system.

B．To create a ship to collect waste in the oceans.

C．To collect the floating plastic waste piece by piece.

D．To gather up the floating plastic waste in the oceans.

26．What can we know about the “System001”?

A．It was a failure.                                         B．It was a great success.

C．It worked with a parachute.                         D．It needed to be fueled regularly.

27．What does the underlined word mean in Paragraph 3?

A．vast                       B．rough                     C．calm                      D．peaceful

【分析】

這是一篇説明文。文章講述每年有大量塑料垃圾被衝入海洋並漂浮在海面上，一個叫做Ocean Cleanup的團隊研製出了收集塑料垃圾的工具並不斷地進行完善。

24．推理判斷題。根據第一段Every year, over 7.72 trillion kilograms of plastic is washed into the oceans. There are five huge areas in the world’s oceans that are a “soup” of floating rubbish. One of these areas, the Great Pacific Garbage Patch (GPGP), is three times as large as France.可知每年有超過7.72萬億公斤的塑料被衝進海洋。世界上有五個巨大的海洋區域是漂浮垃圾的“湯”。其中的大太平洋垃圾帶（GPGP）的面積是法國的三倍。由此可推知，在第一段中，作者通過列數字的方式是想表達海洋中的塑料污染已經成為一個嚴重的問題。故選C。

25．細節理解題。根據第二段中Over a year ago, a group called Ocean Cleanup began using a huge floating screen to try to clean up plastic pollution in the ocean. After several failures, the group is now collecting plastic in the Great Pacific Garbage Patch.可知一年多前，一個名為海洋清理的組織開始使用一個巨大的浮動篩來清理海洋中的塑料污染。經過幾次失敗後，該組織現在正在大太平洋垃圾帶收集塑料。由此可知，這個團體的計劃是收集海洋中漂浮的塑料垃圾。故選D。

26．細節理解題。根據第三段中But it soon became clear that the screen was just moving with the plastic, not collecting it. Sometimes plastic would wash over the top of the tube. Even worse, System 001 got broken by surging seas and had to be towed to Hawaii for repairs.但很快就發現，這塊篩只是隨着塑料的移動而移動，而不能收集垃圾。有時塑料會從管子的頂部沖洗出來。更糟糕的是，System 001被洶湧的海浪打破，不得不被拖到夏威夷進行維修。以及第四段第一句But Mr. Slat, who got the idea for the Ocean Cleanup system, sees the project as an experiment, which means a failure is a chance to learn.可知但產生海洋清理系統想法的Slat認為，這個項目是一個實驗，也就是説，失敗是一個學習的機會。由此可知，System001失敗了。故選A。

27．詞義猜測題。根據上文Even worse, System 001 got broken可知有更糟糕的是，系統001被洶湧的海浪打破，不得不被拖到夏威夷進行維修。由此可知，劃線單詞意思為“洶湧的，猛烈的”。故選B。
