Before you start imagining a humanlike robot walking around the classroom, Will is just an avatar that appears on the student39。根據(jù)最后一段中的“At a meeting in Versailles, France, on November 16th, 2018, the world39。 （3）考查細(xì)節(jié)理解。s measurement bodies achieve at the meeting held in Versailles? will e up with seven new SI units. will set May 20th as a new international festival. will redefine four SI units including the kilogram. will decide on a new measure used in the laboratory.【答案】 （1）B（2）D（3）A（4）C 【解析】【分析】本文是一篇說明文，法國凡爾賽宮舉辦的國際計(jì)量大會，將對目前使用的國際單位制中的四個(gè)基本單位進(jìn)行重新定義，其中包括對千克的重新定義。 Although John Wilkins, an Englishman, first put forward a decimal system (十進(jìn)制) of measurement in 1668, it was the French who in 1799 made it law. The Syst232。然而，它們也會釋放出有害 的故選C。millipedevulturebeing plain in taste at the discovery of a predatorB. While faking and fierce looks are among animals great defenses, many species know that everyone runs from a big stink (臭氣) too. （4）考查推理判斷。People should take a positive attitude to new technology.【答案】 （1）C（2）C（3）A（4）B 【解析】【分析】本文是一篇說明文，介紹一種水上無人機(jī)可以用于清理浮在水面上的垃圾。Swallow it.Avoid crashing into it.It can frighten sharks away.B. Our drones are designed to move through a water system, whether it39。 A shark moving around the coastline is normally a worrying sight，but this waterborne drone (無人機(jī)) threatens floating rubbish instead of people.s attitudes towards littering.（1）What do we know about the WasteShark? A.The importance of ocean protection.（3）What will the WasteShark do with an approaching object? A.C.The production cost of WasteSharks should be reduced.D.根據(jù)第五段中的Fitted with a collisionavoidance system, the drone uses laser imaging detection and ranging technology to detect an object in its path and stop or back up if the object approaches.可知，配備防碰撞系統(tǒng)，無人機(jī)使用激光來探測物體，用測距技術(shù)來探測前方是否有物體，如果探測到物體，無人機(jī)就會停下來或者后退，故選A。s eyes and face.t move any more than a human statue until the threat has passed. Sea Hare (海兔)t know how appealing it is.（1）The sea hare defends itself from predators by ________. A.The gas released by millipede was basically harmless.（3）The species that enjoys more than one defense mechanism is ________. A.C.Sea Hare (海兔)部分中的“The sea hare gives out a slimy, purple ink, the substance which makes food less palatable to predators.”可知，海兔身上散發(fā)出黏糊糊的紫色墨水，這種物質(zhì)使得捕食者對食物不那么感興趣，從而保護(hù)自己免受捕食者的傷害。根據(jù)Millipedes (千足蟲)部分中的“Their major defense is to curl up into a ball. They, though, also release a harm eyes, and leave a horrible smell on their attackers.”可知，千足蟲主要防守是蜷成一團(tuán)。s measurement bodies are almost certain to approve a decision that will mean four out of the seven base SI units, including the kilogram, will follow the other three, including the metre, in being redefined in terms of the values of physical constants (物理常數(shù)).Each of the chosen constants has been measured incredibly precisely, which would mean that from May 20th 2019 the constants will themselves be fixed at their current values for ever. Any laboratory in the world will then be able to measure, for example, the mass of an object as precisely as the accuracy of their equipment will allow.（1）What does Paragraph 1 mainly tell us? went before libra in measurement. things used to be adopted as measures. were accepted as measures by the Romans. measurement systems were gradually formed.（2）How does the author develop the second paragraph? time order. analysis. space order. parison.（3）Which of the following countries used SI as an official measurement? ....（4）What will the world39。故選D。 （4）考查細(xì)節(jié)理解。 While the start of a new school year is always exciting, this year was even more so for some elementary school students in Auckland, New Zealand.

A.This technology is far from mature.（4）From the last paragraph, we can draw a conclusion that____.

To measure these ancient temperatures, researchers look to ice cores (冰核) and lake deposits. Since ice and lake deposits form by a gradual buildup on annual layers of snow or mud, these cores contain history of the past. By looking through the layers, researchers can obtain climate clues from centuries ago.（1）Why are the remains of flies mentioned in the first two paragraphs? serve as evidence that there is still life in the Northwest Greenland. were one of the many ancient lives that were left in the Greenland mud. are indicators that Greenland was much warmer than previously thought. help the researchers realize that there was once a warm period in the Arctic.（2）The new information about Greenland is important because______________. have no idea how to measure Greenland39?？芍?，在前兩段中提到蒼蠅的殘骸是為了證明格陵蘭島的溫度比之前認(rèn)為的要高得多?？芍?，格陵蘭島覆蓋了這個(gè)北極國家的80%，擁有相當(dāng)于全球海平面20英尺的冰。7．閱讀理解 Jill Spisiak Jedlicka is his greatgrandniece.
