Question

【題目】 Both globes and maps help you find where the places are．Both show you the size and shape of the places， too． But maps are flat pictures． Often， they show just a part of the earth． Globes are round like balls． They are models of the earth． They show the whole planet． Maps are light and easy to carry． Globes are heavier and harder to manage． They usually stay in one place． Maps and globes both show directions and distance.

Mercury and Venus are closer to the sun than the earth． However， Mercury is 36 million miles away from the sun． Venus is 67 million miles away． It takes Mercury 88 days to orbit（沿軌道運行）the sun． Venus spends about 230 days orbiting once around the sun．Venus is about the same size as the earth． Mercury is much smaller． Both Mercury and Venus get very hot．Scientists do not think there is life on either planet．

As dolphins and porpoises（鼠海豚）are very similar， people often cannot tell the differences between them． Both dolphins and porpoises are mammals like lions and whales． They can be seen in the oceans， seas and rivers．They are so intelligent that they have the ability to think， understand， and learn things quickly and well． They have large，complex brains．They make sound waves to help them know things well and find their ways in the water．Dolphins and porpoises feed on fish． The main difference is that dolphins like talking a lot and love to communicate with people as they are together．They make whistling sounds through their blowholes to communicate with one another． Porpoises are usually timid and shy．

【5】D

【解析】

短文大意：本文是科普文，第一段介紹了地球儀和地圖的區(qū)別和作用，第二段介紹了水星和金星的差別，第三段介紹了海豚和鼠海豚的相似之處和主要區(qū)別。

【1】題意：地球儀和地圖有什么相似之處?考查細節(jié)理解題，根據(jù)" Both show you the size and shape of the places"兩者都能告訴你這些地方的大小和形狀，可推斷地球儀和地圖都能展示一個地方的大小和形狀，故選B．

【2】題意：根據(jù)短文，哪幅圖是正確的?考查內(nèi)容判斷題．根據(jù)" Mercury and Venus are closer to the sun than the earth． However， Mercury is 36 million miles away from the sun． Venus is 67 million miles away"水星和金星比地球離太陽近．然而，水星距離太陽3600萬英里．金星在6700萬英里之外，可推斷水星和金星比地球離太陽近，且水星比金星離得更近，故選B．

【3】題意：在文章中帶下劃線的單詞“afraid”是什么意思?考查詞義理解題．根據(jù)"The main difference is that dolphins like talking a lot and love to communicate with people as they are together"主要的區(qū)別是海豚喜歡說很多話，喜歡和人交流，可知言外之意是指鼠海豚的性格和海豚不同，應該更內(nèi)向一點．A項“膽小的”與后面的“害羞的”相對應．故選A．

【4】題意：海豚和鼠海豚有何不同?考查細節(jié)理解題．A. Dolphins live in the water海豚生活在水里。B. Porpoises feed on fish海豚吃魚。C. Dolphins are friendlier海豚是友好的。D. Porpoises have large brains海豚擁有大的大腦。根據(jù)"The main difference is that dolphins like talking a lot and love to communicate with people as they are together."主要的區(qū)別是海豚喜歡說很多話，喜歡和人交流，可知海豚更友好，ABD三項是相同的．故選C．

【5】題意：根據(jù)短文，下列哪個選項是正確的?考查細節(jié)理解題．A. Globes show just a part of the earth地球儀顯示地球的一部分。B. Scientists think there is life on Mercury and Venus科學家認為水星和金星上的生活。C. It takes Mercury more time than Venus to orbit once around the sun水星繞太陽一周的時間比金星繞太陽一周的時間要長。D. Dolphins and porpoises make sound waves to help find their ways海豚和鼠海豚使聲波來幫助找到自己的方式。根據(jù)" They make sound waves to help them know things well and find their ways in the water"他們制造聲波來幫助他們了解事物和找到他們在水中的路，可知海豚和鼠海豚都通過制造聲波來幫助他們找到路，D項說法正確，故選D．
