Grammar Practice

Write down all the infinitives with the function of purpose from the text. Compose 2 sentences with the Infinitive in this function.

2. Form nouns from the following words:

to detect, to produce, to help, to utilize, to fit, to miniature, serious, human.

Choose the necessary suffixes from the “word-flower” and add them to the words. Translate nouns into Ukrainian.

3. Match the modal verbs and their equivalents in the appropriate tense form:

a) can	1) have to
b) could	2) is able to
c) may	3) was permitted to
d) might	4) is allowed to
e) must	5) was able to

4. Find the sentences in the text where the - ed form of the verb is a part of the passive construction and make them interrogative.

20. Step Forward For Nanotechnology: Controlled Movement Of Molecules

an advance	просування	self-healing	самозагоювання

Scientists in the United Kingdom are reporting an advance toward overcoming one of the key challenges in nanotechnology: getting molecules to move quickly in a desired direction without help from outside forces. Their achievement has broad implications, the scientists say, raising the possibility of coaxing cells to move and grow in specific directions to treat diseases. It also could speed development of some long-awaited nanotech innovations. They include self-healing structures that naturally repair tears in their surface and devices that deliver medication to diseased while sparing healthy tissue. Mark Geoghegan and colleagues note long-standing efforts to produce directed, controlled movement of individual molecules in the nano world, where objects are about 1/50,000^th the width of a human hair. The main solutions so far have involved using expensive, complex machines to move the molecules and they have been only partially successful, the scientists say.
