30、“allow”, we know “which” guides non-restrictive attributive clause, referring to “spacesuits”.)5) Splendid as the view of the earth is, spacewalking is not as exciting as you might think. Its probably the most dangerous work, with potential risks such as electric shocks. Thats why every spacewalk is

31、 carefully planned. 5) “It” refers to “spacewalking”. “That” refers to the main content of the preceding text. 6) Its luxury to eat fresh food, because fresh produce such as fruit and vegetables can only be delivered to the space station from the Earth every couple of months. 6. to eat fresh food (“
